Superconductor without limits 10.03.2023

Scientists have developed a material that exhibits superconducting properties at normal temperature and relatively low pressure. Engineers from the University of Rochester have unveiled a new material, nitrogen-doped lutetium hydride. It exhibits superconducting properties at a temperature of 20,5 °C and a pressure of 10 kbar. The development opens up a wide range of practical applications for such materials, from loss reduction in power plants to maglev and efficient electronics. In most cases, superconductivity, a property in which a material has zero resistance, requires temperatures close to absolute zero and extremely high pressures to occur. Researchers have already used hydrides, created by combining rare earth metals with hydrogen, as high-temperature superconductors. But they also require a pressure of several Mbar to work, which makes the practical application of materials difficult. Rare earth hydrides form framework structures in which and ... >>

The moon gradually increases the length of the day on Earth 09.03.2023

Billions of years ago, a day on Earth lasted less than 13 hours. And it continues to grow constantly. The reason for this is the connection between the Moon and the oceans. Throughout human history, the Moon has been a ghostly presence above the Earth. Its gravity sets the rhythm of the tides, and its pale glow illuminates the night. Entire civilizations set calendars on it, and some animals, like dung beetles, navigate in space with the help of sunlight reflected from the surface of the moon. According to some theories, perhaps it was thanks to the Moon that life appeared on Earth. The eccentric orbit around our planet is also thought to play a role in some important climate systems. But the moon is also gradually moving away from us. Performing his perfectly balanced astroballet around the Earth - the Moon rotates, but never completely, we always see only one side of it - it is gradually moving away from our planet. Scientists call this process "lunar recession". mediation ... >>

AirPods already have options that partially allow you to use the device as a hearing aid, reminds Gurman. For example, amplifying the sound during a conversation. However, they are not certified as medical devices. And Apple, apparently, wants to enter the healthcare market. Another reputable insider, Ming-Chi Kuo, previously reported that the Cupertino company has already received several patents related to the use of headphones as a medical device. Among them are sensors hidden in the headset that collect data on the pulse, body temperature and perspiration level. ... >>

Whole-grain diet reduces the risk of cardiovascular disease 08.03.2023

A new Harvard study found that women who ate two to three servings of whole grains a day were 30% less likely to develop heart disease compared to those who ate less than one serving of grains per week. Similar indicators are in men - participants in the experiment. Thus, old-fashioned oats and other foods rich in beta-glucan and fiber, which is responsible for removing cholesterol from the bloodstream, can claim the title of the most beneficial food for the heart. Whole grains provide our body with more than just fiber - they are a source of B vitamins, iron, magnesium and other beneficial substances. They also provide protein that helps muscles and cells function properly. The fiber in whole grains contributes to the feeling of fullness, which helps prevent overeating, which leads to obesity and, consequently, the risk of cardiovascular disease. Nutritionists have proven that people who eat a lot of whole ... >>

Viscous liquid of electrons flowing in graphene 06.03.2023

For the first time, scientists have directly measured the "liquid flow" of electrons in graphene at nanometer resolution. Physicists at the University of Wisconsin-Madison have observed how a stream of electrons turns into an analogue of a viscous liquid when it encounters interference inside a conductor. Graphene is a two-dimensional atom-thick carbon material arranged in a honeycomb pattern. It is a pure electrical conductor in which electrons practically do not feel resistance. For the experiment, the researchers added obstacles at controlled distances to the graphene and then applied an electric current through it. "In the study, we show how charge flows around an impurity, and actually see how this impurity blocks current and causes resistance, which has not been done before to distinguish between gaseous and liquid electron flows," says Zak Krebs, a graduate student in the Wisconsin Physics Department. University of Wisconsin-Madison and co-author of the study The study found that when ... >>

Very early classes have a negative impact on student achievement 06.03.2023

Scientists have done extensive research to show how getting up early affects student learning. It turned out that morning classes in colleges or universities reduce the performance of students. The researchers were able to estimate class attendance by examining university Wi-Fi login data from more than 20 students. They separately collected data from over 180 students over a 6 week period. The experts learned that class attendance at 8 am is 10 percent less than class attendance at the end of the day. Students did not wake up on time in almost a third of classes that started at 8 am. The team then investigated the impact of morning classes on student sleep by studying the online intensity of nearly 40 students. The scientists say the students went to bed around the same time but woke up earlier to attend morning classes. So, the duration of the night's sleep was shorter only than those nights that preceded the morning classes. Considering sleep and attendance disruption, the study ... >>

The benefits of a four-day work week have been proven 04.03.2023

In the UK, an experiment has come to an end in which more than 60 companies reduced the working hours of their employees by 20% - for six months they worked only four days a week. And because of this, their well-being and health improved. The study was conducted by a team of scientists from the University of Cambridge, Boston College and the British think tank Autonomy. The experiment involved about 2 employees from industries ranging from IT and financial services to healthcare. As early as three months after the start of the experiment, when company executives summed up intermediate results, the positive effects of a four-day work week were observed. They confirmed the results of similar but smaller projects in the US and Ireland. And six months later, the results were generally excellent. 900% of employees said they had reduced work fatigue, and 71% experienced less stress in the workplace. The four-day week also had a positive effect ... >>

Earth's deepest region discovered 04.03.2023

New scientific evidence shows that the Earth's innermost core is starkly different from the rest of the planet's center. To understand planetary origin and evolution, scientists have been exploring the center of the Earth for a very long time, and recently they made a huge discovery related to the inner core of the planet Earth. Until recently, it was believed that the crust, mantle, outer core and inner core make up the structure of the Earth. But a new study by Australian scientists confirms that there is, in fact, a fifth layer. Scientists have made previously unheard-of observations of a mysterious metal ball at the deep core of the Earth, revealing a structure that has long been a subject of conjecture but has never been seen in such detail, according to a new study. The researchers said that intensive study of the Earth's interior, based on the behavior of seismic waves from strong earthquakes, confirmed the existence of a distinct structure inside the inner core of our planet - through ... >>

Artificial intelligence received copyright 02.03.2023

The United States Copyright Office (USCO) has made a decision on a comic created using the Midjourney neural network. Representatives of the department said that the copyright of the artist Kris Kashtanova on the comic "Dawn of the Dawn" (Zarya of the Dawn) applies only to the part of the book that the writer wrote and designed herself. The images generated by Midjourney are owned by AI. The Copyright Office intends to reissue the book registration, where it excludes images that are not the product of human authorship. The agency accepted that Kashtanova "is the author of the text of the work, as well as the selection, coordination and organization of textual and visual elements." However, not all images presented in the comic "are the product of human authorship." In September, photographer Chris Kashtanova announced that she had received the copyright for the Dawn of Dawn comic book, which she wrote with the help of Midjourney. However, a few months later, USCO withdrew its decision, emphasizing that earlier work ... >>

Girls' brains develop faster 01.03.2023

American scientists have found significant differences in the structure of the brain of boys and girls during their growing up. To conduct the study, a sample of 8,9 thousand children aged 9-10 years was compiled. Their parents were asked to periodically bring their children for brain scans using an MRI machine. Scientists were interested in changes in the structure of gray and white matter in the brain, as well as gender differences in these changes. As a result, it was possible to confirm the long-standing hypothesis that the ways of development of the male and female brain are significantly different. In particular, significant differences were recorded in the structure and pace of development of the network of the passive mode of the brain, which plays an important role in the functioning of the brain during inactivity. As a rule, girls were characterized by a higher density of connections between neurons in this network, as well as an increased density of white matter in the regions of the brain associated with it. According to scientists, this reflects the fact that the brains of girls and girls ... >>

The internet can help you lose weight 01.03.2023

Today, you will not surprise anyone with fitness gadgets and smartphones, but there are very, very few rigorous studies on the topic of helping devices to lose weight. Researchers from the University of Tsukuba have shown that the use of gadgets and web applications can help in the fight against excess weight. It is unlikely that someone needs to explain the harm of excess weight to health and life expectancy. Every extra kilogram turns into a risk of type XNUMX diabetes, cardiovascular disease, hypertension and many other troubles. Experts have created many working methods to combat obesity. In recent years, there has been a surge of activity in the field of solutions using web applications and gadgets. However, the degree of their impact has not been strictly analyzed, which does not allow us to identify the most effective tools for solving the problems of gaining excess weight. Therefore, Japanese scientists decided to create a base for such research. Experts evaluated the effectiveness of using web applications for incentives ... >>

The shortest electronic explosion is generated 27.02.2023

Have you ever wondered why your computer and other electronic devices are sometimes fast and sometimes slow? It all comes down to the speed at which electrons, the smallest particles of our microcosm, flow out of tiny wires inside the transistors of electronic circuits and create pulses. Developing ways to increase this speed is critical to unlocking the greatest performance potential of electronics and its software. But what is the shortest time for electrons to flow out of tiny lead metal in an electronic circuit? Using extremely short laser flashes, a team of researchers led by Prof. Eleftherios Gulielmakis, head of the Extreme Photonics Group at the Institute of Physics at the University of Rostock, and staff at the Max Planck Institute for Solid State Research in Stuttgart used the state of the art today. While it has long been known that light can release electrons from metals (Einstein was ... >>

Ice cream that doesn't melt in the sun 26.02.2023

Everyone has faced the problem when ice cream in the hot sun turns into a white mess very quickly. To avoid this, Ben & Jerry's and Magnum treats are undergoing a new revolution. And while the British consumer giant hasn't revealed exactly how the new ice cream will be made, experts say the answer likely lies in either using more starch or removing some of the sugar. conditions, which is part of the drive to save energy and reduce carbon emissions. However, the difficulty of the latter lies in the fact that minor changes in the ice cream formula can affect the delicate balance between texture and taste. The reason ice cream stays soft and easy to savor is because sugar lowers the freezing point of the water it's in, explained an expert from the University of Guelph in Canada. According to scientists, the number ... >>

Hot air balloon tours in the stratosphere 25.02.2023

The Japanese company Iwaya Giken has begun accepting applications for high-altitude balloon tours. The double capsule will ensure the delivery of the pilot with one tourist to a height of 25 km. It will be possible to feel like a quarter of an astronaut for a relatively modest amount of about $180. As the project develops, prices promise to fall significantly, which will make "flights into space" accessible to a wide range of citizens. The tourist capsule looks like a barrel with a diameter of 1,5 m with transparent walls, ceiling and floor. A helium balloon will lift the capsule into the sky. The system, as you might guess, is reusable. In the future, the developers promise flights at intervals of a week, or maybe even more often, but everything will depend on the weather. Flights to the ISS under space tourism programs cost several tens of millions of US dollars per person. Rising on reusable shuttles into the stratosphere to the edge of space by Virgin Galactic and Blue Origin is also not a cheap pleasure. Ideally ... >>

Tree fungus - an ecological alternative to plastic 25.02.2023

Scientists have discovered that the tinder fungus (Fomes fomentarius), which grows on trees, has several surprising properties. Researchers believe it could become a natural biodegradable alternative to certain plastics and other materials in the future. This wood-eating fungus has historically been used to start fires, but also in clothing and medicine. Now it can have a whole new level of utility as a biodegradable alternative to plastic. The mycelium, composed of thin filaments known as hyphae, forms root-like networks that spread through soil or rotten material. A team of scientists from research institutions in Finland, the Netherlands and Germany say this network can be divided into three separate layers. Mycelium is the main component in all layers. However, in each layer, the mycelium exhibits a very distinct microstructure with a unique preferred orientation, aspect ratio, density, and branch length. The researchers studied the ... >>

Mozart's music may help reduce epilepsy attacks 24.02.2023

According to research by scientists at Dartmouth College (USA), listening to Wolfgang Amadeus Mozart's "Sonata for Two Pianos in D Major K.448" for 30 seconds reduces bursts of neuronal activity. They are responsible for epileptic seizures in patients who do not respond to conventional therapies. A high number of neuronal peaks is associated with memory loss or cognitive decline and even a higher incidence of epileptic seizures. Treatments that can reduce these peaks will help people with epilepsy. Scientists conducted an experiment involving 16 volunteers who did not respond to traditional treatment for epileptic seizures. They were given to listen to Mozart's music for 15 seconds. Other different musical genres were also tested, among which modern works were presented. But it was Mozart's music that had the desired effect on the patients. Experts explain this by the fact that the sonata has a beneficial effect on brain activity. ... >>

Larks are descendants of Neanderthals 24.02.2023

A new study suggests that we owe our ability to wake up at the first rays of the sun to Neanderthals. It is known that our circadian rhythms or biological clock works as a built-in regulator of sleep and wake cycles. This built-in timing system is influenced by many different environmental factors, but circadian genes also play a role - all together they affect whether we are early birds or night owls. In the new study, scientists have focused on studying how our genes influence how our body clock works and to whom we owe it. The scientists used sequence-based machine learning techniques to identify archaic variants in the human genome that affect circadian rhythms. The results of the study suggest that every time we manage to wake up early and get to work, meeting or school on time, we should be thanking our old cousins ​​- Neanderthals for this. explored ... >>

Superbread for weight loss 23.02.2023

Experts from the Institute of Biological Sciences, King's College London and the Norwich Food and Health Research Center (UK) have used chickpea cell flour instead of wheat flour. Many dieters avoid bread due to its high carbohydrate content. However, nutritionists have managed to develop a unique bread recipe using chickpea cell flour. Such bread tastes better than wheat bread. It induces a feeling of satiety and helps to lose weight. During the traditional grinding of chickpeas, lentils and legumes, their fibrous structure is destroyed. But a new method of grinding chickpeas helps preserve it. Thanks to this, products based on such flour receive additional nutritional properties. The experts decided to find out how bread regulates the feeling of fullness, and also affects the level of insulin and blood sugar. To do this, they baked three types of buns: one made from wheat flour, and in the other two, wheat flour was replaced with chickpea flour by 30% and 60%, respectively. ... >>

Microbes stop water from blooming 22.02.2023

Excessive growth of algae is harmful to aquatic ecosystems. However, it can stop as suddenly as it started. Bacteria, which previously coexisted peacefully with plankton, begin to attack it and quickly destroy it. Scientists were able to identify the substance that triggers such an attack. Perhaps it can be used to control the flowering of reservoirs. Single-celled algae Emiliania huxleyi live in a close community with a variety of bacteria. Usually, their relationship can be called friendly: photosynthetic algae share some of the nutrients with microbes, and at the same time supply compounds that are useful to them. For example, rhodobacteria provide vitamin B, which planktonic algae are unable to produce on their own. But in adverse circumstances, microbes easily betray their partners: as soon as there is not enough food, rhodobacteria destroy E. huxleyi. Such fragile relationships are not uncommon in nature, they also exist in our intestines. And for aquatic ecosystems ... >>

Scientists brought together identically charged particles 21.02.2023

It is likely that the charged particles are reluctant to react with each other because they are repelled electrostatically. However, scientists have discovered how to bring them closer. The new method can speed up the reaction by up to 5 million times, according to the Institute of Physical Chemistry of the Polish Academy of Sciences. Thanks to the research of an international group with the participation of Poles, the rate of chemical reactions in aqueous solutions can be controlled in a new way. It is enough to add particles of opposite charge to the solution, which will force the previously disgusting reagents to approach each other. The use of molecules with a high charge density can speed up the reaction up to 5 million times. The synthesis of new compounds or the production of materials is extremely complex at the molecular level. Two molecules with the same charge repel each other, so they rarely react with each other. This reaction may take days, weeks, or even longer. However, this time can be significantly reduced by using ... >>

The formula for the happiest songs has been discovered 21.02.2023

The researchers found that these tracks have the usual structure, but spiced up with unpredictable elements. Music is what makes us feel better when we are down. Scientists have long found out that funny songs can bring a smile back to our face even on the most cloudy day. However, what makes these songs so fun? University of Sheffield music psychologist Dr Michael Bonshor has discovered the formula for the happiest songs in the world and believes that The Beach Boys' Good Vibrations is the best fit. A music psychologist has found that inspirational tracks have a certain tempo and a regular structure - as a rule, their tempo is 137 beats per minute (bpm), and the structure is very trivial: verse-chorus. However, these tracks also have their own "zest" - for the most part they are seasoned with unpredictable elements. For example, a key configuration or an additional note. According to Bonchor, we probably like seventh chords, because about ... >>

Wood will trap carbon dioxide 20.02.2023

The modern world is focused on the fight against climate change, and in the scientific aspect, this fight reaches, at first glance, unexpected areas, such as the creation of building materials that absorb carbon dioxide emissions. Now scientists have invented a new way to produce wood that makes it stronger and captures CO2 from the air when used in construction. Carbon dioxide is recognized as the main driver of climate change. Limiting carbon dioxide emissions associated with the production of structural materials such as steel, metal and cement is a way to address climate change indirectly. A direct approach is to reduce atmospheric carbon dioxide emissions by capturing it in structural materials. Scientists at Rice University in Texas have used the natural properties of wood to increase its ability to capture carbon dioxide. The process involves the incorporation of highly porous metal-organic framework (MOF) microparticles into other ... >>

Marriage affects blood sugar 20.02.2023

An international team of scientists conducted a study in which scientists measured average blood sugar levels in older people. It turned out that life in marriage allows you to maintain a normal level of glucose in the blood. The study examined the relationship between marital status, marital quality, and average blood glucose levels in older people. The participants were 3335 people aged 50 - 89 years, not suffering from diabetes. For ten years, they asked if they were in a relationship and how their marital status had changed. They were also asked questions that would help to understand how warm and supportive the relationship between the subjects and their partners is. According to the data obtained, when entering into marriage or partnership in the blood test, there was an improvement in such an indicator as glycated hemoglobin. It allows you to understand what was the level of glucose in the blood over the past few months. So, life in a couple led to a decrease in this indicator. And it's great, sweat ... >>

Hydrodynamic analogue of radiation from oil 17.02.2023

American and French scientists obtained in a vibrating vessel with oil a hydrodynamic analogue of radiation - an effect from quantum optics. Due to vibrations, waves formed on the surface of the oil, provoking the appearance of drops, just as ensembles of atoms are able to emit light through a collective interaction with each other. The experiment of physicists highlighted the features of the quantum effect, and will also find application in the calculations of hydrodynamic systems. When the atoms in an ensemble are very close to each other, less than a wavelength apart, they interact with each other through an electromagnetic field, which allows them to collectively emit photons, and at a greater intensity than any individual atom. This phenomenon is called superradiance and is not only of theoretical interest to scientists, but also of practical interest, because it can be used in a variety of fields related to optics: from lasers to quantum information technologies. IN ... >>

Fairy robot for plant pollination 15.02.2023

A team of researchers from the University of Tampere, Finland, has created an almost invisible work of 5 millimeters. The FAIRY fairy robot, which looks like dandelion seeds, uses the energy of light and wind to propel itself. It will help pollinate plants in season. The device is so light that the wind can carry it from flower to flower. All processes will continue under the supervision of specialists. They will encourage the artificial pollinator to work and guide with visible light. In dark and calm weather, the "fairy" stands motionless. When there is enough light, the structure automatically opens and flies in the wind. The new device is powered by a light source such as an LED. The fairy robot will help solve the problem of insufficient pollination of plants and trees on which food security and biodiversity depend. The challenge for scientists is to increase the sensitivity of the robot's material so that it can work in any light and carry biochemical compounds. ... >>

Liquid laser that does not evaporate in air 14.02.2023

Scientists have created a cheap and easy to manage and use liquid laser. Physicists at the University of Tsukuba in Japan have developed a tunable laser based on liquid droplets. Unlike previously created drop lasers, the new device does not require special conditions. The technology will help create cheap and flexible devices for optical communication. For their development, the researchers used the "lotus effect". These plants are known for their ability to clear dust. Through microscopic tubercles on the surface of the leaf, water drops do not escape, but form almost perfect spheres that roll down, capturing dust particles with them. Scientists have used a similar approach to create liquid droplets that can act like lasers while remaining stable until the moon. They used 1-ethyl-3-methylimidazolium tetrafluoroborate ionic liquid and mixed it with a dye. Researchers coated quartz substrate for "liquid laser" with fluorine nanoparticles ... >>

Solar panels from lunar soil 14.02.2023

For decades, researchers have been talking about using lunar regolith as a material from which to create solar panels, because it contains all the necessary substances: silicon, iron, aluminum, etc. Since the Apollo mission brought lunar soil to Earth, there have been hundreds of thematic research papers and relatively modest engineering developments. Blue Origin said that as part of its own two-year Blue Alchemist program, it learned how to make solar panels and electrical wires from a material that mimics the composition of moon dust. Engineers at the space company Jeff Bezos used a process called "molten regolith electrolysis," where a material that mimics the composition of lunar regolith was supplied with a constant electric current at a temperature of 1600°C. Thanks to this, iron, silicon and aluminum were separated from the material. Blue Origin says it has produced silicon with a purity of over 99,999%. By-products from the reaction ... >>

Smart windows based on the octopus organism 13.02.2023

People came up with the idea of ​​building houses and buildings to be less dependent on the weather and the environment. However, maintaining comfortable conditions inside requires continuous expenditures for lighting, heating or cooling. According to 2021 data, they account for 30 percent of the world's energy consumption, generating about a quarter of all greenhouse gas emissions. And the ongoing global warming only increases these figures. The main channels through which buildings heat up in the heat and cool in the cold are windows. They let rays of different wavelengths pass through, and together with the light, heat inevitably penetrates inside - or is lost in vain, leaving for the street. Therefore, scientists and engineers are trying to create more technological glass that would not interfere with natural light, but at the same time would block other types of radiation. For example, they can automatically dim in bright light. However, such solutions are not flexible enough, and ideally, the window should be able to change bandwidth flexibly. So ... >>

Analog quantum simulators 13.02.2023

Classical computers are not suitable for solving new fundamental problems in the field of physics and beyond. In the future, universal and error-tolerant quantum computers can help scientists with this, but such will not appear soon. However, if the problem cannot be calculated, then why not do experiments? An analog quantum simulator can become a constructor of the quantum world, which will help to reveal the most mysterious physics beyond theory. Researchers from Stanford University in the United States and University College Dublin (UCD) in Ireland published a paper in the journal Nature Physics in which they talked about creating a new type of highly specialized analog computer (more precisely, a simulator). Scientists have presented one element of such a "computer" - two specially connected nano-sized metal-semiconductor components built into an electronic circuit. The proposed solution imitates the interaction of two elementary particles, in this case, atoms and electro ... >>

Stars that form gold are discovered 12.02.2023

Astronomers using a telescope at the Inter-American Observatory of Cerro Tololo, Chile, have discovered for the first time a binary star system that, when it explodes, produces gold, platinum and uranium. It is noted that this is a very rare phenomenon, since when stars explode, their entire outer shell flies into space, and the core shrinks to a minimum size, forming a neutron star. In rare cases, the explosion is not too strong. This is what happened to the neutron star SGR 0755-2933. It, along with the ordinary star CPD-29 2176, is located at a distance of 11 light-years from Earth. "The fact is that the star SGR 400-0755 turned into a neutron star as a result of a "silent" supernova explosion about 2933 million years ago, but after another 1 million years its companion will also turn into a neutron star in the same way. After which both stars will approach each other and they will collide. As a result, there will be a powerful explosion - a kilonova," say astronomers. According to them, the explosion of the kilonova leads to ... >>

An efficient way to extract hydrogen from sea water 11.02.2023

The electrolysis process to extract green hydrogen typically requires large amounts of clean water - up to 9 liters for every kilogram of hydrogen. However, an international group of researchers from Australia, China and the USA proposed in their article a more economical method using sea water - without any pre-treatment, but with an acid coating on the catalyst (water was split with almost 100% efficiency). "In this work, we demonstrate the direct electrolysis of seawater that has not been pre-treated, but only filtered to remove particulate matter and micro-organisms," the scientists said. The team says a typical electrolyser catalyst can be made with cobalt oxide and chromium oxide on the surface. Normally, sea water destroys catalysts due to severe erosion caused by chloride ions; also accumulated insoluble deposits of magnesium and calcium block the electrodes - however, scientists have solved this problem, just add ... >>

Light travels forward and backward in time at the same time 11.02.2023

By separating a photon using a special optical crystal, two independent teams of physicists have achieved what they call a quantum time flip, in which the photon exists in both a forward and backward time state. The effect arises from the convergence of two strange principles of quantum mechanics that contradict certain rules. The first principle, quantum superposition, allows tiny particles to exist in different states or different versions of themselves at the same time, as long as they are not observed. The second principle, the symmetry of charge, parity, and time reversal (CPT), states that any system containing particles will obey the same physical laws, even if the particle charges, spatial coordinates, and motions in time are reversed, as in a mirror. By combining these two principles, physicists created a photon that seemed to simultaneously move along and across the arrow of time. "The concept of the arrow of time gives word to the apparent unidirectionality of time, which ... >>

Adults and children perceive time differently. 10.02.2023

It is well known that the perception of time changes with age, and now Hungarian researchers have been able to figure out why this happens. The perception of time in children and adults is noticeably different: a forty-minute seminar is more likely to seem short to an adult, and for many first-graders, sitting out so much time in a lesson is a difficult test. Of course, the perception of time is influenced by many factors, from a person’s temperament to saturation with emotionally charged events, but researchers from the Etvos Loran University (Hungary) decided to study the influence of one of the main factors: the age of the subject. The experiment involved 138 people divided into three groups: "preschoolers" (4-5 years old), "schoolchildren" (9-10 years old) and "adults" (18 years old and older). All participants were asked to watch a couple of videos lasting one minute: these were excerpts from a popular animated series, balanced in visual and acoustic richness, but differing in events. One video presented ... >>

Electric cars help reduce asthma risk 09.02.2023

Scientists from the US have found that the widespread use of electric vehicles will not only reduce air pollution, but also have a positive impact on the risk of developing asthma in people. This is the first study using concrete data on the impact of electric vehicles on the environment and humans. It was held in California, where most people get around in electric vehicles. The study found that every 20 electric vehicles contributed to a 3,2% reduction in medical attention requests due to asthma. Asthma is most often associated with nitrogen dioxide (NO2), which is released into the atmosphere with exhaust gases and contributes to the development of not only asthma, but also other respiratory diseases, as well as problems with the brain and heart. In the past decade, there has been a sharp boom in electric vehicles in California, and their number has increased 10 times. In areas dominated by electric vehicles, the air was cleaner and people complained less about health problems. ... >>

12 new satellites discovered around Jupiter 09.02.2023

The list of Jupiter's satellites has been replenished with 12 more, which increased the total number of satellites of the giant planet to 92. They were discovered in the past two years with the help of ground-based observatories. In addition to being the largest planet in the solar system, Jupiter also has the largest number of satellites, which continues to grow. Of the 92 already known, the largest are the so-called Galilean satellites - Io, Europa, Ganymede and Callisto, and the closest are Metis, Adrastea, Amalthea, Theba. Orbital data for 12 more were discovered and confirmed from 2021 to 2022. The dimensions of all new satellites are between 1 and 3 kilometers, so not even all of them will receive official names, according to the rules of the International Astronomical Union. The found satellites need from 550 to more than 700 days to complete an orbit around Jupiter - 9 of 12 are among the 71 most distant satellites of the planet, said Carnegie Institution of Science astronomer Scott Sheppard. ... >>

Seamless 3D skin grafts 08.02.2023

Researchers at Columbia University have printed perfectly fitting seamless 3D skin grafts for burn patients. The main disadvantage of the grafts that are printed on bioprinters today is that they can only be produced as flat sheets with open edges. This method, according to a team of researchers from Columbia University, ignores the completely enclosed geometry of human skin. Scientists have developed a new way to produce skin in almost any complex 3D shape, from ears and elbows to entire arms. The project was named "Creation of seamless human skin with improved biomechanical properties". The scientists explained that they designed the skin as a completely enclosed 3D tissue that can be molded to the shape of a body part and easily transplanted. In addition, these homogeneous grafts perform better (both mechanically and functionally) than alternatives. The manufacturing process looks like this: the place of transpla ... >>

A new form of amorphous ice has been obtained 07.02.2023

A team of British chemists has ground ordinary ice in a ball mill at a temperature of 77 kelvins and obtained a new form of amorphous ice. This is the name of ice, which, unlike crystalline ice, Ih does not have an ordered molecular structure. The open form was stable at atmospheric pressure up to 1,1 gigapascals. Scientists gave it the name amorphous ice of medium density. The phase diagram of water reveals about 20 of its crystalline forms, as well as two amorphous phases, characterized by a lack of order in the arrangement of molecules. The latter are divided into two types: amorphous ice of high and low density. At atmospheric pressure and a temperature of 77 kelvins, the first has a density of 1,13 g per cubic centimeter, and the second - 0,94 g per cubic centimeter. At the same time, they have been known since the last century, and no amorphous forms of ice have been found during this time in the density interval between them. However, the curiosity of scientists does not weaken, because it is amorphous ice, as you think ... >>

liquid metal robot 03.02.2023

Scientists in China have created a shape-shifting work that could resemble one of the characters in the cult film Terminator 2: Judgment Day. The machine has the unique ability to break out of prison on its own. And this is without additional equipment. How is this possible? A group of scientists led by Chenfeng Pan from the Chinese University of Hong Kong presented their new achievement in a short one-minute video. It features a miniature model of a prison and a small shape-shifting robot behind bars. The device looks like a Lego figure. The robot is controlled by magnets. At some point, he "opens up" and pours between the bars, getting out of the mini-prison. Finally, it returns to its original state, that is, the solid state. The behavior of the work may be reminiscent of a scene from the movie "Terminator 2: Judgment Day", in which one of the characters "flows" through the bars of the hospital to hunt his victim. The robot is made of gallium, a low temperature metal ... >>

Time may not exist 02.02.2023

The researchers found that causality, not time, is the main characteristic of our universe. Australian Catholic University expert Sam Baron believes that physics is in crisis. For the past century, scientists have been explaining the universe in terms of two extremely successful theories: general relativity and quantum mechanics. According to him, quantum mechanics successfully justifies working in the incredibly tiny world of particles and their interactions. At the same time, the general theory of relativity describes the general picture of gravity and the movement of objects. These theories largely contradict each other. Therefore, scientists believe that they should be replaced by one common. In particular, we are talking about the theory of "quantum gravity", which should explain how gravity works on the smallest scale. At the same time, scientists note that creating a new theory of quantum gravity is an extremely difficult task. One such attempt was string theory. She replaced the particles with strings, in ... >>

A touch from a distance 02.02.2023

Japanese researchers have unveiled a system that allows users to transfer physical sensations and tactile information between devices. Japanese mobile network operator NTT Docomo, together with Keio University's Embodied Media Project and Nagoya Institute of Technology's Haptics Lab, have developed the Feel Tech platform, which "makes it possible to share experiences that are usually difficult to convey through images, sound, text or words." The inventors plan to use the technology in a variety of use cases, including healthcare, sports, education, and e-commerce. In particular, they plan to focus on medicine and art. In addition, they suggest using the platform to "experience the subtle feel of clothing fabric, among other rich experiences that are not possible with other advanced technologies such as 3D or augmented reality." The system determines the sensory state of a person and helps ... >>

Graphene on platinum surfaces defies Coulomb's law 01.02.2023

Researchers from Basel and Tel Aviv have found that friction changes with speed in specific graphene structures on platinum surfaces, violating Coulomb's law, which states that friction is independent of velocity in the macrocosm. Materials made from individual atomic layers are highly valued for their low friction properties, useful for reducing friction on hard drives or moving parts of satellites or space telescopes. Composed of a single layer of carbon atoms arranged like a honeycomb, graphene is a prime example and is being tested for its potential as a lubricating layer. Earlier research has shown that graphene tape can slide across a gold surface with almost no friction. If graphene is applied to a platinum surface, this has a significant effect on the measured friction forces. Now physicists from the Universities of Basel and Tel Aviv have figured out that in this case the friction depends on the speed at which the tip of the atomic force microscope moves across the surface. ... >>

Hydrogen train from CRRC and Chengdu Rail Transit 01.02.2023

The world's largest rail vehicle manufacturer has released a zero-emission train that uses a combination of hydrogen fuel and a supercapacitor as a power source. The train consists of 4 cars, has a range of 600 km and can reach speeds of up to 160 km/h, making it the fastest hydrogen rail vehicle in operation today. The development belongs to the state-owned industrial enterprise CRRC and Chengdu Rail Transit. The train operates 5G, as well as automatic start, stop and return to depot modes. Hydrogen is considered a clean energy source because water vapor is the only by-product that is released when it is burned. It does not produce harmful substances, pollutants or greenhouse gases. In addition, hydrogen can be produced from a variety of sources, including renewable resources such as wind, solar and hydropower, further increasing its potential as a ... >>

Coffee with milk acts as an anti-inflammatory 31.01.2023

Coffee with milk has an anti-inflammatory effect on the body, scientists from the University of Copenhagen found. Whenever bacteria, viruses, and other foreign substances enter the body, the immune system reacts by using white blood cells and various chemicals to defend itself, and this causes inflammation. In addition, inflammation can be caused by oxidative stress - damage to cells as a result of oxidation by oxygen. Polyphenols are known to be beneficial to humans as they help reduce oxidative stress. "When a polyphenol reacts with an amino acid, its inhibitory effect on inflammation in immune cells is enhanced. We tested immune cells treated with a combination of polyphenols and amino acids. They were found to be twice as effective at fighting inflammation than cells to which only polyphenols were added. ", the researchers noted. Coffee beans are high in polyphenols and milk is rich in proteins. therefore ... >>

Cabin for communication with a hologram of the interlocutor 31.01.2023

The developers of the PC accessories manufacturer Logitech presented a prototype of the Project Ghost video chat booth - inside it you can communicate with a realistic projection of the interlocutor. Starline is based on a set of sensors and cameras to create a hologram-like projection, while Project Ghost is based on video conferencing technology from Logitech. Once in the cockpit of Project Ghost, the user will be able to communicate with the interlocutor through a device resembling a box with a display, camera, microphone and speakers. The entire cockpit comes as part of the Rally system, which is certified for video conferencing platforms such as Zoom, Microsoft Teams and Google Meet. To create a human projection, Logitech developers placed a special type of glass at an angle behind the display. A similar technique was used on one of the Disneyland rides. Logitech promised to showcase the new product at the Integrated Systems Europe (ISE) conference this week in Barcelona. Logitech representatives will collect ... >>

Generation of electricity from moving trains 30.01.2023

Researchers at the Virginia Tech Center for Vehicle Systems and Safety, along with colleagues from the Railroad Technology Laboratory, are going to collect and use the energy generated by moving trains. They want to use the resulting energy for sensor systems and other security and monitoring systems. The fact is that more than 75% of US railroads are located in rural areas, and it is difficult and costly to connect electricity to them. Solar panels do not always save, because they can be damaged by bad weather or simply stolen by intruders. Therefore, scientists propose to use something like a hybrid of a conductive subway line and generators. The passing train will put pressure on special beams, for its part, generators will rotate, which will transmit the generated electricity through the cable. In other words, ancient as the world system of a dynamo and a bicycle wheel in a modern high-tech design. Scientists suggest using ... >>

Titanium Dioxide Increases the Emission Intensity of Laser LEDs 30.01.2023

Titanium oxides significantly increase the efficiency and photoluminescence of LEDs. The dominance of white LEDs as the main source of light may soon end with the emergence of a new alternative. The photonic crystal or nanoantenna, a two-dimensional structure with a periodic arrangement of nanosized particles, is being developed as an advanced optical control technology. Exposure of light to a combination of a nanoantenna with a phosphor plate produces a harmonious combination of blue and yellow light. White LEDs have already received an improvement in the form of white laser diodes (LD), which consist of yellow phosphors and blue laser diodes. Blue LDs are highly directional, while yellow phosphors radiate in all directions, resulting in unwanted color mixing. To solve this problem, the researchers developed phosphor plates in combination with nanoantennas using aluminum metal, which allows increasing photoluminescence. Aluminum nanoparticles effectively scatter light ... >>

Transmission of radio signals with almost no energy consumption 29.01.2023

According to the second law of thermodynamics, any process of energy transfer (including radio waves) is associated with its costs. That is, in fact, it is impossible to create a "perpetual motion machine", because without the expenditure of energy it cannot produce it. But scientists from Stanford managed to create a data transmission technology that uses almost no energy at the receiver. They found that in the case of receiving a radio wave transmission, the energy does not have to come from the transmitter. In many cases, such as when transmitters need to be small and portable, their consumption can be reduced or eliminated by backscattering technology. In this case, the only power needed for the transmitter is used for the transistor. Because the transmitter uses very little power (enough to switch a transistor), it doesn't need bulky batteries. The idea is that the signal source has a higher temperature than the antenna, so that when the circuit is closed, it will start ... >>

Rolls-Royce hydrogen generators 29.01.2023

Rolls-Royce is preparing to present environmentally friendly electric generators running on pure hydrogen. According to DataCenter Dynamics, from 2024 it is planned to supply 1 MW models based on methane generators already produced under the mtu brand. Rolls-Royce is also developing fuel cells for data centers. In the future, it is planned to use only "green" hydrogen, obtained by electrolysis from water using the energy of solar cells and wind farms. It is known that so far we are talking about an artificial product - two generators will be delivered in January 2024 to Germany. This is a refinement of an existing model that runs on methane - mtu Series 4000 L64. The new version is designed for use with pure hydrogen. It is important that methane and hydrogen have a large difference in physical and chemical properties, so Rolls-Royce had to work hard to create a truly reliable hydrogen generator. ... >>

Edible packaging for fish 28.01.2023

The SeaFilm food packaging project, funded by the European Marine and Fisheries Fund, has created a biodegradable food film. This was done by researchers from the Polytechnic University of Leiria in Portugal. The quality and shelf life of any product depends on the packaging. Therefore, in Israel, they created a plastic film that will keep the products fresh, and then it is easy to dispose of. Now, according to Thefishsite, the package of frozen fish can be eaten. The international project SeaFilm has developed a replacement for single-use plastic film. The film is made from bioactive seaweed extracts. Once the fish is thawed, the biodegradable film can either be thrown away or eaten with the fish. The edible film may include seasonings to create delicious, convenient, and easy-to-prepare meals. Studies have shown that this can extend the shelf life of seafood and salmon once thawed and inhibit microbial growth. ... >>

Its main difference is a screen with Full HD resolution and a diagonal of 13,3 ″ or 15,6 ″, as well as only two speakers for sound reproduction. Past Galaxy Books were considered among the best ultraports ... >>

Use of film costumes for disease research 27.01.2023

The technology of fixing the movements of actors, which James Cameron used in his cult film "Avatar", was adapted by scientists to track the progression of diseases of the musculoskeletal system. With the help of the latest technology, scientists will be able to track the development of diseases that prevent movement. These include any diseases associated with the brain and nervous system, heart, lungs, muscles, bones, and a number of mental disorders. In tests using motion-capture suits, a new system that uses artificial intelligence for analysis, British experts measured the severity of two genetic disorders twice as fast as top doctors. In the long run, this will help patients get the right support and treatment faster. In addition, it could halve the time and significantly reduce the costs required to develop a new drug in clinical trials. Dr. Ricotti, who was part of the research team at Imperial College and Univer ... >>

Nuclear mining center 27.01.2023

Cumulus Data has completed the construction of the first building of a mining center in Pennsylvania (USA), which will use exclusively nuclear energy. Bitcoin mining is scheduled to start in the first quarter of 2023. The mining complex will cover an area of ​​1200 acres (486 ha) and will be the first center of its kind in the United States. In addition to bitcoin mining, he will also be involved in cloud computing. The new center will be powered by the Susquehanna Nuclear Power Plant, located nearby in this area in northeastern Pennsylvania. The power of this energy source is 2,5 GW, which should fully ensure the operation of the center. Nuclear power has significant potential in the context of mining, as it is considered an environmentally friendly way to mine bitcoins (there is no "carbon footprint"). The stable operation and significant power of such centers is key to ensuring the stability of the entire Bitcoin ecosystem. In many cases, nuclear power plants cannot use ... >>

High Speed ​​Travel to Mars 26.01.2023

NASA has selected several new space projects for possible implementation in the future. Among them is the project of American scientists, which consists in using a new type of nuclear engine in a space rocket so that it can fly to Mars in 45 days. NASA now has very far-reaching plans for space exploration, and therefore actively attracts scientists to develop new technological projects that can be implemented in space. Focus has already written about some of them, which concern, for example, the creation of an oxygen pipeline on the Moon and a new aircraft for flights on Titan. At this stage, NASA has selected 14 projects that initially received funding for further development. That is, this is only the first phase of the study, and only a few projects will go to the third phase. NASA is going to blow up astronauts to the moon in a few years, and then at the end of the decade to begin construction of the first lunar base. The next step in space exploration will be landing ... >>

Beam of cold atoms without laser cooling 26.01.2023

American physicists managed to obtain lithium atoms with a temperature of 10 millikelvins by cooling them in a stream of helium gas and trapping them in a magnetic trap. In terms of efficiency, their method turned out to be no worse than laser cooling, but it can be used with a large number of types of atoms and expand the area of ​​application of cold atomic beams. It is much easier for experimental physicists to work with atoms, ions and molecules in a chilled state. Cooling down to temperatures below one kelvin minimizes the kinetic energy of the particles, making them more controllable. So they can be sharpened into traps, used for high-precision measurement experiments, such as atomic interferometry, as well as studying quantum phenomena and exotic forms of matter. In their new experiment, physicists at the University of Texas at Austin have proposed a new way to produce continuous beams of cooled atoms. The most used method of cooling atoms is laser cooling. ... >>

Photosynthesis battery 25.01.2023

Plants are often considered sources of food, oxygen, and decoration, but not a source of electricity. However, scientists have found that by using the natural transport of electrons in plant cells, it is possible to produce electricity as part of a biological ecological solar cell. Scientists have used a succulent plant for the first time to create a living "bio-solar battery" powered by photosynthesis. Electrons are naturally transported as part of biological processes in all living cells, from microbes and fungi to plants and animals. Through the introduction of electrodes, the cells can be used to generate electricity that can be used outside. Previous research has created fuel cells using bacteria, but they need a constant supply of food. This new approach uses photosynthesis, the process by which plants convert light energy into chemical energy, to generate electricity. During this process, the light starts ... >>

Light pollution makes it difficult to see the stars 25.01.2023

Being able to observe cosmic events and view the full breadth of the stars of the universe from the comfort of your backyard is one of the oldest joys that skywatchers must contain. However, a new study suggests that the glow of the sky is becoming too bright, and light pollution obscures the stars. Although scientists have found the best place on Earth to watch the stars, we don't have to move there just to see the sky in all its beauty. The night sky is getting seven to ten times brighter every year as man-made light emission from the Earth continues to grow. In 2006, a project was launched to observe this growing sky glow, with researchers from Germany and the United States taking part. The project is known as Globe at Night. This project is a public science project and recently a team of researchers analyzed over 50 observations made with the naked eye between 000 and 2011. For this 2022 ... >>

The secret of chewing chocolate 24.01.2023

A team of scientists from the University of Leeds focused not on the taste of chocolate, but on the tactile sensations associated with eating it. The analysis was performed using a premium brand of dark chocolate on a 3D artificial tongue-like surface. The scientists applied the analytical methods of tribology, one of the branches of engineering that studies the interaction of surfaces and liquids, the level of friction between them and the role of lubrication: in this case, saliva or fat from chocolate. "Tribology provides a mechanistic understanding of how food feels in the mouth. This knowledge can be used to develop products that taste better, have better texture or are healthier," explains Anvesha Sarkar, professor at the School of Food Science and Dietetics in Leeds. When chocolate hits the tongue, it releases a fatty film that coats the tongue and other surfaces in the mouth. It is through it that we feel chocolate as something smooth and pleasant. After that, cocoa solids are released, which become more important. ... >>

Abandoned mines to save energy 24.01.2023

Researchers at the International Institute for Applied Systems Analysis (IIASA) have proposed using a new technology to create a so-called gravitational energy storage through decommissioned mines. The method is called Underground Gravitational Energy Storage (UGES). Its essence is to store energy by transporting sand to decommissioned underground mines. UGES generates electricity by lowering sand into an underground mine and converting the potential energy of the sand into electricity through regenerative braking. Then, by lifting the sand from the mine to the upper reservoir using electric motors to store energy when electricity is cheap. The main components of UGES are the shaft, engine/generator, upper and lower storage areas and mining equipment. The deeper and wider the shaft, the more electricity can be extracted from the plant, and the larger the shaft, the greater the capacity of the energy storage. Thanks to the sand ... >>

Controlling lightning with a laser beam 23.01.2023

Lightning is one of nature's most energetic phenomena, releasing millions of volts in a fraction of a second, which can be devastating - power outages, fires, injury and even death. For a long time, the best way to protect yourself from lightning was considered a lightning rod - a huge metal stick attached to the tallest building. This simple design essentially draws electricity and guides it safely into the ground. However, one of the problems is that such lightning rods have a limited range - for example, a 10-meter lightning rod can only protect an area with a radius of 10 meters around it. That is, to protect a large building or airport, a giant lightning rod would actually be required. But it looks like scientists have found a way. Physicist Aurélien Houart of the Applied Optics Laboratory of the French National Center for Scientific Research in Paris and his colleagues withstood many hours of thunderstorm activity to test whether a laser could retract ... >>

Leisure time has a detrimental effect on a person 23.01.2023

The best option is to do nothing - no more than two hours a day. American researchers from the University of California and Pennsylvania found that excess free time negatively affects a person. In particular, the feeling of his well-being. Scientists analyzed data from two surveys of more than 35 Americans. In which the participants talked in detail about what they did during the previous day and how it affected them. It turned out that the state of health improved with the increase in free time, but it was no more than two hours. But after five hours of free time, the state of health, on the contrary, worsened. Two online experiments were also conducted, in which more than six thousand people took part. For six months, each participant received from 15 minutes to seven hours of free time. The experiment showed that people with the minimum and maximum time felt worse. ... >>

Robots have been taught to smell 22.01.2023

The developers of Tel Aviv University taught the works to smell with the help of a biological sensor. The sensor sends electrical signals in response to the presence of an odor nearby, which the robot can detect and interpret. This biological and technological breakthrough was made by doctoral student Nata Shvil from the Sagol School of Neurology at Tel Aviv University, Dr. Ben Maoz from the Fleishman Department of Engineering and the Sagol School of Neurology, and Prof. Yossi Yovel and Prof. Amir Ayali from the Sagol School of Zoology and the School of Neuroscience. The developers have created a platform in which biological sensors and electronics are integrated. It allows you to use the biological nose in a certain place using an electronic device. Locust antennae are used as a biological sensor. Scientists have made an autonomous chassis with artificial intelligence and sensors. The algorithm learned to recognize eight "pure" smells, including geranium, lemon and marzipan, plus two mixtures of different smells. In t ... >>

Appearance can affect longevity 22.01.2023

Specialists of the School of Medicine of the University of Washington (USA) believe that some features of physiognomy contribute to a long and happy life. Can a young appearance mean a longer life? Yes, scientists believe. In 2009, they conducted a study on the relationship between appearance and longevity. It turned out that people who look young or even childish cause others to care. Previously, experts suggested this. They were based on the reaction of adults to photographs of babies. This time, they found that seeing children activates the nucleus accumbens, a key structure in the brain's mesolimbic system. It is responsible for pleasure, reward and motivation in nulliparous women. The involvement of this system is a neurophysiological mechanism that entails the motivation to leave, regardless of the degree of relationship. Simply put, the more childlike a person looks, the more willingly the environment takes care of him. This, in turn, affects the duration ... >>

Tense thriller helps you fall asleep soundly 21.01.2023

Researchers at the University of Friborg in Switzerland found in an experiment that revisiting tense thrillers has little effect on sleep quality and can help you fall asleep. The researchers recruited 50 young people who watched three television episodes before going to bed in a specially designed laboratory. Half of the participants watched disturbing thrillers. The other half received a documentary showing communities off the coast of continental Europe dealing with energy problems. In the experiment, the researchers tracked their stress levels by monitoring their heart rate and cortisol levels, and asked volunteers how stressed they were at different times. The results showed that although stress was increased by watching tense movies, participants' sleep quality remained unchanged, with neither total sleep time nor number of awakenings significantly different between the groups. Despite high pre-sleep arousal, participants fell asleep faster after ... >>

The temperature of the world's oceans has been rising for four years in a row 21.01.2023

In 2022, the world's oceans reached their highest temperature on record for the fourth year in a row, according to new research. This is clear evidence of human-caused climate change. Sea surface temperatures have a major impact on the world's weather, with warmer oceans associated with more extreme hurricanes, heatwaves, droughts and heavy rainfall. Since 1970, the oceans have absorbed about 90% of the excess heat from greenhouse gas emissions. Ocean temperatures are less susceptible to short-term weather changes than air temperatures, making the oceans a good indicator of the effects of climate change. A warmer ocean also means more water, rising sea levels and flooding. The oceans are rising, and more and more, the rise is accelerating. The scientific work also studied the salinity of the ocean, which determines the density of water and affects the circulation of the ocean. Scientists have found that the difference between the average salinity in ... >>

Hyperloop analogue tested in China 20.01.2023

The China Aerospace Science and Industry Corporation (CASIC) has conducted the first successful launches of a transportation system similar to Elon Musk's Hyperloop. The test was carried out using a full-sized passenger capsule. CASIC engineers conducted a series of three trial runs of a maglev capsule (superconducting magnets or electrodynamic suspension, EDS) in Datong, Shanxi province. The speed of the capsule reached 50 km/h. Next-generation capsules are planned to carry passengers and cargo at 1000 kilometers per hour or even faster in an "almost" vacuum tube. If all goes according to plan, this type of transport network will become the fastest land transport system in the world. Fast high-speed trains can run at speeds up to 350 km/h. They could move even faster, but then the drift of the rails and energy consumption will increase significantly. And the magnetic levitation technology on which Hyperloop is based, among other things, eliminates friction that wears out the rails, ... >>

Tea is good for the brain 19.01.2023

It has been proven that drinking tea has a positive effect on brain function and allows you to better cope with creative tasks. Researchers at Peking University conducted a series of experiments to see if tea could improve brain intelligence and so-called convergent thinking. It is the kind of thinking we use to solve problems. The findings show that regular consumption of tea benefits the intellect, as well as many other health benefits, to which you can add an increase in life expectancy. The results of the experiments showed that tea is especially good at helping to cope with complex tasks. Moreover, tea lovers are particularly resilient in the sense of solving these problems, and at the same time they do not get tired. The experiments involved 100 people who went through tests for vocabulary associations or other linguistic tasks of varying complexity. Each participant was given the opportunity to drink a cup during ... >>

paper battery 19.01.2023

Scientists from Singapore have learned how to make batteries from household waste that are twice as good as those used by modern smartphones. Nanyang Technological University has developed a new method to process disposable paper packages, bags and cartons into electrodes for rechargeable batteries. The researchers used a laser to cut paper waste into thin sheets with gratings of various shapes, then they were heated to 1200 degrees Celsius in a special furnace without a flame. As a result, paper turned into pure carbon, water vapor and oils. The scientists turned the extracted carbon into electrodes, and the resulting cells showed superior durability, flexibility, and electrochemical properties associated with the structure of paper fibers. Laboratory tests have shown that a battery with such an anode can withstand up to 1200 charge and discharge cycles - twice as much as modern smartphone batteries. In addition, they are five times better withstanding ... >>

Bee vaccine 18.01.2023

The USDA has approved the world's first honey bee vaccine. This should help in the fight against American foulbrood, a disease that usually devastates bee colonies. The drug is a weakened bacterium. Once in the body of the queen bee, it triggers the production of specific immunity for the larvae that she will give birth to. The vaccine will initially be available to commercial beekeepers. "Our vaccine is a breakthrough in protecting honey bees. We are ready to change the way we care for insects, which in turn will affect food production globally," said Annette Kleiser, chief executive of vaccine developer Dalan Animal Health. ... >>

Synthesized a new form of carbon 18.01.2023

Carbon can take on a wide variety of forms. The most famous of them are diamond and graphite. Scientists are able to synthesize other types, for example, two-dimensional graphene and fullerene. Now another one has been added to the list. Specialists from South Korea and China have created a new kind of carbon by heating fullerene with lithium nitride. The new type of carbon is similar to Schwarzite, but still different. The so-called "schwarzite" or sp2-hybrid carbon with negative curvature was theoretically envisaged as early as the 60th century. He, as the study says, was and remains the dream of scientists in the field of carbon materials, but there were problems with obtaining it. Although this kind of carbon can be synthesized in the pores of zeolites, the crystalline forms of silicon dioxide, this method is not ideal because some of the pores are simply too small. The new material is based on CXNUMX fullerene powder mixed with lithium nitride and then heated to moderate temperatures under pressure in one ... >>

The influence of a child's nutrition on his future character 17.01.2023

Scientists from the Institute of Military Epidemiology in Oslo found that the nutrition of a mother during pregnancy and a child under the age of seven years can be associated with the character and mental health of the child. A total of 40 pairs of mothers and children were included in the study. Mothers filled out questionnaires when the child was six months old, 566 months old, three years old, seven years old and eight years old. The analysis found that a healthy maternal diet was associated with higher scores on conscientiousness, extraversion, agreeableness, and imagination, and lower scores on neuroticism in children. Healthy eating for mothers during pregnancy and for children between the ages of six months and seven years was associated with lower depression scores in children at age eight, but there was no significant association between diet and anxiety. At the same time, nutrition at the age of seven years had a stronger effect on the risk of developing depression than nutrition in infancy. The authors noted that all participating mothers were non-smokers and p ... >>

Discovered a fundamentally new way of cooling 17.01.2023

Standard refrigeration systems operate with refrigerated gas as it expands. This method is extremely efficient, but the gases used in it are extremely harmful to the environment. In a new study, a team of scientists from Lawrence National Laboratory and the University of California at Berkeley focused on inventing a revolutionary way of cooling that was not only efficient and cost effective, but also environmentally friendly. The new method the researchers have developed is called ionocalloric cooling, which takes advantage of the storage and release of energy when the phase of a material changes, such as when water changes from solid to liquid. According to mechanical engineer Drew Lilly, one way to make ice melt without heating is to add a few charged particles or ions. The most common example of this in action is the salting of ice in winter - essentially the ionocaloric t cycle. ... >>

Artificial organic neurons 16.01.2023

Researchers at Linköping University (LiU), Sweden, have created an artificial organic neuron that closely mimics the characteristics of biological nerve cells. This artificial neuron can stimulate natural nerves, making it a promising technology for various medical procedures in the future. At the LOE Organic Electronics Laboratory, work continues to develop increasingly functional artificial nerve cells. In 2022, a team of scientists led by assistant professor Simona Fabiano demonstrated how an artificial organic neuron can be integrated into a living carnivorous plant to control the opening and closing of its mouth. This synthetic nerve cell matched 2 of 20 characteristics that distinguish it from a biological nerve cell. Researchers at LiU have developed a new artificial nerve cell called conduction-based organic electrochemical neuron, or c-OECN, that accurately mimics 15 of the neurons. 20 neural about ... >>

Super Yielding Rice 16.01.2023

An international team of scientists has developed a hybrid high-yielding rice that will help avoid starvation in poor countries. Hybrids of the first generation of cultivated plants show greater productivity than their parental strains. Breeders call this hybrid activity. But this phenomenon does not persist if the hybrids are bred together in the second generation. Therefore, when farmers want to use highly productive hybrid varieties of plants, they are forced to buy new seeds every season. Rice is the staple crop of half of the world's population. At the same time, it is expensive to breed it as a hybrid to increase yields even by 10%. Scientists believe that the reproduction of hybrids in the form of clones that do not change from generation to generation can solve this problem. The new method is expected to produce hybrid seeds quickly. It will also provide farmers with seeds they can store and replant. This method can be applied to other food products. ... >>

Early retirement negatively affects the brain 15.01.2023

Scientists at Binghamton University have found that early retirement can negatively impact the brain and accelerate cognitive decline. The researchers analyzed an array of data on the health status of retirees in China. Scientists believe that the negative impact of early retirement on the brain may be due to a decrease in social activity. The new study focused on government health data from a pension scheme introduced in China in 2009. Due to rising poverty among older people in some rural areas of the country, the program offered people a stable income if they retired within a few years of reaching age 60. By collecting decades of data, the researchers were able to compare the health and cognitive outcomes of those participating in the early retirement program with a matching group of people who are still working in their 60s.

Water battery for electric vehicles 14.01.2023

Electric vehicles flooded with salt water during hurricanes and other natural disasters are at risk of fire because they can corrode the battery and cause a short circuit. But scientists at the University of Central Florida have developed technology that can prevent electric vehicles from catching fire and cut battery charging time to three minutes. Currently, electric cars are predominantly equipped with lithium-ion batteries with an organic electrolyte in their composition. However, such electrolytes are too volatile and can easily flare up due to overcharging, overheating, and water corroding the battery case. Scientists have created a so-called "water" battery - replacing the organic electrolyte with salt water to create a safer and more efficient battery. This is not the first attempt at using salt water as an electrolyte, but previous concepts have suffered from low energy output, slow charge times, poor stability and corrosion. The Californians succeeded ... >>

Silence after snowfall 14.01.2023

Snowy winters are beautiful in their own right, but many of us may have noticed that after a snowfall, something magical happens on the street - an unusual silence sets in, which we would hardly be able to observe on any other day. A peculiar silence is partly due to the less active person who involuntarily comes after a snowfall, but not only. This effect is also partly related to the acoustic damping effect of snow. Today scientists decided to shed light on this "magic effect". Going outside after a snowfall may well seem "magic", because the effect of snowy landscapes is significantly emphasized by the change in the soundscape - it seems that everything on the street suddenly subsides. This interesting effect of all-consuming silence is partly due to a decrease in human activity - there are fewer people on the street, less traffic on the roads. In addition, construction sites are shut down, road repairs are delayed, and other sources of anthropogenic noise are silenced. Even singing ... >>

Diagnosing a cold before symptoms appear 13.01.2023

Researchers from the University of Michigan have found that the process of reduced immunity followed by SARS is preceded by a temporary but noticeable decrease in cognitive abilities. Scientists conducted a study in which 18 participants tested their attention, reaction time and ability to switch between numbers and symbols three times a day. On the fourth day of the study, the group was purposefully exposed to the human rhinovirus (HRV), commonly responsible for the common cold. Throughout the days, participants lavaged their noses to measure the presence and volume of viral cells shed. Volunteers were also asked to rate their well-being based on eight symptoms, including fever, cough, headache, nasal congestion, runny nose, sneezing, sore throat and fatigue. After all, those who shed the most virus and had severe symptoms tended to show fluctuating cognitive performance in the days leading up to their illness. The authors of the study ... >>

A new way to cool air 12.01.2023

The technique, proposed by scientists from the University of California at Berkeley, is to add charged particles and electricity to the environment. With their help, you can make the ice melt without heating, cooling the air around. The new method was called ionocaloric cooling. Strictly speaking, something similar has been used for a long time - for example, when treating icy roads with salt. In this case, the ions on the surface are associated with water molecules in the semi-liquid layer. With different molecular orientations, this causes water molecules to separate from the surface layer and increase its temperature-determined thickness, so most of the ice block melts when it joins the surface layer. The California scientists' discovery was to add electricity to this cycle. The researchers simulated the ionocaloric cycle by running a current through it. The latter, passing through the system, moved the ions, shifting the melting point of the material and changing the temperature. So they managed to change t ... >>

Ancient Roman concrete can be restored 12.01.2023

A group of researchers from the Massachusetts Institute of Technology, Harvard University and laboratories in Italy and Switzerland have been able to recover a long-standing concrete technology. Engineers believe that this material has withstood a millennium thanks to "hot mixing". During the hot mixing process, the lime fragments form a brittle nanoparticle architecture, creating an easily brittle and reactive source of calcium that ensures the concrete's ability to recover. Tiny cracks that form in concrete pass through lime chips with a large surface area. When reacted with water, this material forms a calcium-saturated solution, which turns into calcium carbonate and quickly fills the crack. In their work, the engineers drew attention to the fact that ancient concrete samples contain small, characteristic, bright white millimeter-scale mineral elements. These formations are formed from lime, one of the key components of the ancient concrete mix. Previously, scientists believed that ... >>

Ventilator to help you breathe 11.01.2023

Experts from the Massachusetts Institute of Technology have developed a soft, robotic and implanted ventilator. The device, based on two soft tubes, works like artificial muscles and enhances the movements of the diaphragm. As a result, the patient with the implant can "breathe deeply". The base of the device is soft tubes resembling balloons. They are implanted under the diaphragm - a dome-shaped muscle located in the chest cavity, the movements of which ensure normal breathing. The tubes are placed across the diaphragm and attached to the chest on either side of this muscle. When inflated with an external pump, the tubes act like artificial muscles, pushing against the diaphragm and helping the lungs expand. In this case, the tubes can be inflated at a frequency corresponding to the natural rhythm of the diaphragm. Scientists note that such a system is more in line with natural breathing than traditional ventilators. They create a positive pressure at which air pushes through ... >>

Secret passages found in the Great Wall of China 11.01.2023

In the Great Wall of China, 130 secret passages were discovered using continuous shooting with a resolution close to a centimeter. Based on further photo analysis and fieldwork, the team penetrated each of the hidden doors designed specifically for the local topography. Historically, some of these secret passages were intended for the passage of scouts. Still others were built as channels of communication between the two sides of the Great Wall or for trade in antiquity. According to some official documents dating back to the Ming Dynasty (1368-1644), some nomadic tribes were allowed to use such secret gates for grazing between Qinghai and Hutao in northwest China, a region with abundant water and grass resources. The practice is also evidenced by some large secret doors through which two horses could pass in both directions, said Zhang Yukun, a professor at Tianjin University and leader of the research team. ... >>

plasma mirror 10.01.2023

For the first time in the history of science, physicists from the LOA laboratory (Laboratoire d'Optique Appliquee), France, have created a so-called relativistic plasma mirror, a region induced by laser light, inside which free plasma electrons move almost at the speed of light. And the most remarkable thing in this case is that this plasma mirror is "updated" at a fairly high rate - about a thousand times per second. When an intense pulse of laser light ionizes the surface of a material target, it creates a cloud of plasma so dense that the whole thing becomes opaque to light, even if the target was previously completely transparent. Laser light is simply reflected from such a plasma mirror. But, during such a reflection, a process called surface higher harmonic generation (SHHG) occurs, which "compacts" the laser light pulses, making them even shorter and more intense, which is of interest to some areas of science and technology. However, "crampy ... >>

Coworking spaces can negatively impact creativity 09.01.2023

Collaborative workspaces may not be as efficient as previously thought. In recent years, coworking spaces have become increasingly popular. But while the idea is that they could promote collaboration and creative innovation through shared ideas between start-ups, a recent study shows that over long periods of such collaboration, the opposite can happen—creativity declines. The IESEG School of Management explored the growing collaboration in co-working spaces in one of the largest dedicated hubs in Europe. Through interviews, archival material, and observations, the researchers created a case study around seven fintech start-ups using coworking spaces. In their article, the scholars noted: Despite the emergence of coworking spaces as new work practices, little is known about the formation of collaboration and, in particular, the emergence of collaborative practices, given these open and flexible workspaces for meetings and networking. ... >>

New refrigeration method for refrigerators 09.01.2023

Scientists at the Lawrence Berkeley National Laboratory have created a cooler using the principle of ionocaloric cooling. A phase transition in a material is associated with energy flows. When a solid body melts, it absorbs energy from the environment, and when it solidifies, it releases it. This remains true even when the phase change is caused by chemical or mechanical changes rather than by heating or freezing the body. The new refrigerant works on the ionocalloric principle. Salt is at the base of the device. The current passing through the system moves the ions, raising the melting point of the material. When melted, the material absorbs heat from the environment, and when the ions are removed and hardens, it gives off heat back. The first experiment was able to cool the material by 25 degrees Celsius using a voltage of less than one volt. This is much more efficient than using similar technologies. The authors of the development are trying to balance three things: ecologist ... >>

The evolution of sleep 08.01.2023

Humans sleep less than other primates. But why does this happen and how much time per day should a person actually spend in a dream? It turns out that people spend less time sleeping than all the great apes that scientists have already studied. For example, chimpanzees need 9,5 hours of sleep per day, oedipal tamarins about 13 hours, and three-banded duruculas 17 hours. At the same time, if you make a model that takes into account all the features of the human body, it will show that a person needs to sleep about 9,5 hours a day. Why is everything different? Scientific research has found the answer. In fact, human sleep is different from primate sleep. People spend less time sleeping and are more in the rapid eye movement phase. Most likely, this is due to the peculiarities of human evolution. Many years ago, human ancestors most likely lived and slept in trees. Today, primates continue to do so. After some time, people began to sleep already on the ground. Because they no longer ... >>

Transmission of optical communication without wires over long distances 07.01.2023

For many years, the idea of ​​6G was considered unthinkable, but associate professor Josep Jornet from Northeastern University in the United States was able to achieve the impossible, writes Techexplore. The basis of communication of the new generation is the terahertz frequency. Thanks to the help of NASA, the US Air Force and Amazon, scientists were able to prove that data transmission at a frequency of more than 100 gigahertz is quite real. Previously, everything was played in 5G and its frequency is 71 gigahertz. But the main problem remained - it was not possible to transmit data over a long distance, because the higher the frequency, the shorter the distance signals can be transmitted. It turned out that even under laboratory conditions it was possible to transmit a signal at arm's length, and this technology had no practical application. But Jornet and his team did not give up. Through a variety of experiments and working with special signal mixers, they injected information directly into the signal source itself. But at the other end they received "information mess", because the signal was very distorted. Then the scientists found elegan ... >>

793 Electric Mining Truck 05.01.2023

Caterpillar has demonstrated the 793 Electric prototype at its Tucson Proving Grounds in Green Valley, Arizona. This proving ground allows potential Caterpillar customers to test trucks over a seven-kilometer distance in scenarios similar to real operations. During the demonstration, the 793 Electric was loaded with material from a quarry to be transported to a nearby train, just like any other heavy truck during normal operations. A fully loaded truck reached a top speed of 60 km/h. The car also had to travel one kilometer up 10% at a speed of 12 km/h, then go down to regenerate energy. After completing the entire run, the truck maintained sufficient battery charge to provide additional cycles, although it was not clear when it would need to be recharged. Caterpillar is rapidly expanding its operations to embrace sustainable energy production using hydrogen and solar power as ... >>

Unmanned spaceship-factory 04.01.2023

Thales Alenia Space will create the first reusable spacecraft factory for the REV Foundation. It is known for funding research in zero gravity and orbital manufacturing. The REV1 should be ready to fly by the end of 2025. The ship is planned to be made completely unmanned, arguing that space stations have strict security measures aimed at protecting human life and health. These are not the most efficient conditions for production, according to the founders of Space Cargo Unlimited, the company that will own the future REV1 spacecraft. “If we talk about large-scale production, then we do not believe in multifunctional ships with people on board. In fact, we believe that production in space should prioritize the cargo, not the ship,” said Nicolas Gaum, the head of the company. On board the ship, the company intends to engage in the production of new materials, biotechnologies and pharmaceuticals, to engage in agricultural ... >>

Equipping the moon with solar panels 04.01.2023

Israeli scientist Jeffrey Gordon from the Department of Solar Energy and Environmental Physics at Ben-Gurion University has developed a conceptual plan for equipping the moon with solar panels. It is estimated that to produce the same amount of electricity would require six times less mass than the best nuclear option. This development will ensure uninterrupted power supply to oxygen plants 100% of the time, with enough panels always in the sun. Gordon's research began when he was approached a couple of years ago by Israeli startup The Helios Project, which is developing a lunar oxygen-producing reactor with the technology. A joint funding approach by the Israel Innovation Authority did not work and the partnership was terminated, but before that, Gordon created his conceptual plan for a solar array belt on the Moon. As part of the experiment, the professor considered three options, one of ... >>

Virus-eating bacteria discovered 03.01.2023

Scientists from the University of Nebraska-Lincoln have discovered a bacterium that feeds on viruses. Researcher John DeLong notes that viruses are quite nutritious, suggesting that there are micro-organisms that deliberately select them for food. They are made of really good materials: nucleic acids, lots of nitrogen and phosphorus. For this, American experts collected water samples from the pond, and also identified a number of microbes. To them, a team of American scientists added chlorovirus, a microorganism that infects algae. For several days, the team tracked the population size of viruses and other microbes to see if the latter were eating the former. Experts have discovered such a microbe - an infusoria known as Halteria. In those water samples in which these bacteria were added, their number increased fifteen times in two days, and the virus itself decreased a hundred times. The second experiment confirmed the assumptions of scientists: experts noticed the DNA of the virus ... >>

Technology for measuring time with an accuracy of up to zeptoseconds 02.01.2023

How fast do electrons move between atoms within the same molecule? Most often, they require only a few attoseconds (10^-18 seconds or a millionth of a billionth of a second). Keeping track of such fast processes is challenging, and a team of Australian scientists recently developed a new interference technology capable of measuring time delays with zeptosecond (10^-21 seconds, or trillionth of a billionth of a second) resolution. As a test, this technology was used to measure the delay between two pulses of light emitted by different hydrogen isotopes, normal hydrogen (H2) and deuterium (D2), which were simultaneously exposed to a single pulse of laser light. The measured delay was less than three attoseconds, and its cause is the difference in the dynamics of motion of lighter and heavier nuclei of hydrogen isotope atoms. Light was emitted by hydrogen atoms through a process called high-energy generation. ... >>

Christmas decorations make us happier 01.01.2023

According to psychologists, Christmas decorations in the house increase the level of dopamine, the feel-good hormone. What makes us happier? First of all, due to the bright lights and colors of New Year's garlands. Chromotherapy, or color therapy, increases energy levels and improves mood. After conducting a series of studies, scientists were able to prove that different colors have their own individual characteristics that favorably affect the nervous system, the internal functioning of the body and the human psyche. The nostalgia factor is also important. For many of us, the New Year is a family holiday filled with home comfort and a magical atmosphere, this is the time when many wishes can come true. Preparing for the celebration, we are immersed in warm memories, which undoubtedly improves our mood. However, if you didn’t have warm moments in the past associated with the New Year, psychologists recommend starting new traditions for yourself - whether it’s going out of town, watching themed films with family and friends ... >>

Sleep patterns change significantly with age 31.12.2022

British scientists managed to collect data on the sleep patterns of 730 people from 187 countries in an unusual way: using the mobile game Sea Hero Quest. The game itself was designed to study Alzheimer's disease and assess differences in the spatial abilities of people from different parts of the world, but at the same time, players also answered other questions about themselves, including reporting age and daily sleep time. It turned out that players sleep an average of 63 hours a day, while women sleep an average of 7,01 minutes longer than men. Eastern European countries such as Albania, Slovakia, Romania and the Czech Republic slept the most, half an hour longer than the global average, while Southeast Asian countries including the Philippines, Malaysia and Indonesia slept the least. Despite the difference in different parts of the world, scientists have identified a general dynamics of sleep duration, which does not depend on gender, place of residence, or level of education: the youngest participants slept the longest. ... >>

Older trees are more drought tolerant 30.12.2022

Protecting older trees is critical in the face of climate change as older trees are more drought tolerant. This was shown by a new large-scale study. Scientists from the University of Michigan (USA) studied the condition of more than 20 thousand trees on five continents and saw that in drought conditions, old trees grow better than young ones. Scientists have concluded that old trees can more effectively cope with current climate changes. Given this find, the scientists emphasized that special attention should be paid to the protection of old forest complexes, calling them "a stronghold of biodiversity." The experts analyzed tree data from the International Tree-Ring Data Bank. We took into account 119 species and their development during and after the drought, focusing on trees whose crowns develop in the uppermost layer of the forest. Trees of each species were divided into young, middle and age. During the study, it was found ... >>

3D printing of tiny details 29.12.2022

Engineers at the California Institute of Technology (Caltech) have developed a new method of 40D printing with pure metals or alloys, which allows for a resolution of 3 microns, which in some cases exceeds the capabilities of other similar technologies by an order of magnitude. The process, which is something of a symbiosis of chemistry and 3D printing, will make it possible to manufacture parts for tiny MEMS (microelectronic mechanical systems) devices that are widely used in space, transportation, biomedical equipment and many other things. The traditional 3D printing process consists of laying down material layer by layer. This, in turn, allows the creation of forms that cannot be obtained by traditional machining methods. Industrial metal 10D printing processes use a laser to melt metal powder at a precise point, and the best of these methods can now achieve resolutions of XNUMX ... >>

The influence of cartoons on the psyche of children 29.12.2022

A study by American scientists showed what changes in the behavior of children after the revision of Disney cartoons. Nowadays, almost every family has a TV, computer or tablet. Children begin to fall under the influence of gadgets from about two years old. Some parents forbid their children to watch TV, considering it very harmful. Others are convinced that watching TV, on the contrary, develops the child and is better able to keep the baby busy for a while. When watching cartoons, the child often identifies with the characters and begins to repeat after them. You may notice that children who do not leave the TV often become nervous and aggressive, impatient and rebellious, and even indifferent to the pain of other people. Thirty-one girls, aged between three and five, were observed during various games. On the playground, the girls behaved like boys, but as soon as it came to dressing up, the girls, dressing up as Disney princesses, changed their behavior dramatically. Scholars of persuasion ... >>

Global warming will increase ocean thermal energy conversion resources 28.12.2022

A Chinese research team has found that the potential capacity of global ocean thermal energy conversion (OTEC) could increase by 46% by the end of this century under a high-carbon scenario. "This is the first study to quantify the state of global OTEC resources in the face of future climate change and provides important scientific guidance for the development and use of OTEC resources in the future," said Jing Zhao, an oceanographic physicist at the Ocean University of China. "OTEC harnesses the large temperature difference between the surface of the sea and the depths of the ocean to generate electricity, providing a renewable solution to fuel our future." In the new study, the scientists estimated the change in global OTEC resources under a high-carbon scenario and analyzed its underlying dynamics based on unprecedented, high-resolution, long-term climate modeling. The results show that warmer ... >>

Cells responsible for alcohol cravings discovered 28.12.2022

Scientists from Sweden have discovered the cells responsible for cravings for alcohol. Studies have shown that nerve cells in the brain are responsible for alcoholism, by turning off which you can get rid of addiction. Alcoholism is one of the most serious problems that some have been struggling with for years. An unhealthy craving for alcoholic beverages spoils the life of not only those who want to drink, but also those around them. However, recently scientists have discovered why this happens and have found a way to stop addiction, learn to say "no". Nerve cells that are located in the brain are responsible for making a decision to drink, with often not very unpleasant and even disastrous consequences. This was found in their study by Swedish scientists from the Linköping University, led by Markus Hailing. New work has revealed in some rodents a tendency to compulsive drinking. That is, to the pathological, not amenable to volitional control, the desire to take alcohol. In order to get a little ... >>

Sturdy plastic that decomposes in a few days 27.12.2022

German chemists at the University of Konstanz have developed a durable and biodegradable plastic. The re-engineered polyester is resilient and stable and resembles HDPE (high density polyethylene) plastic in properties, but contains special “break points” for quick disposal. The new plastic polyester-2,18 consists of two main modules: a short diol unit with two carbon atoms and a dicarboxylic acid unit with 18 carbon atoms. Due to its crystalline structure, it exhibits both mechanical resistance and thermal stability. Plastics are made up of long chains of one or more basic chemical modules (monomers), the scientists explain. Most of the plastics used are characterized by high crystallinity and water repellency. It is these features that make plastic so in demand in industry and everyday life, but they also complicate the natural decomposition. To overcome this incompatibility between stability and biodegradability of plastic ... >>

Wind farms could work on Mars 27.12.2022

NASA scientists have found that there may be enough wind on Mars to use wind turbines as energy sources. In order to simulate conditions on the Red Planet, the researchers adapted a climate model originally developed to study the climate on Earth. Factors such as the amount of solar radiation, dust content in the atmosphere and geographical relief were taken into account, which made it possible to determine the wind speed in different parts of the planet's surface. It turned out that in many regions of Mars strong enough winds blow to contribute to the generation of wind energy, and in some regions the wind strength is sufficient to be the only source of energy. These include crater rims and volcanic highlands, as well as places with ice formations where wind can generate more electricity than solar panels. As the authors write, wind energy compensates for the daily and seasonal decline in solar energy, especially in scientific ... >>

Highly absorbent patch 26.12.2022

Scientists have been able to turn the hydrogel into a patch that can be folded like regular tissue and torn like paper. Usually it is not a big problem for us to wipe the meadow with a rag or kitchen paper. But if you spilled a lot of water on the table, then cleaning can sometimes be annoying. Scientists from the University of Maryland in the USA came to the rescue under the leadership of Srinivasa Raghavan. They developed a hydrogel fabric that absorbs three times more water or other water-based liquids than conventional fabric. A hydrogel is a material consisting of polymer molecules that absorbs water well, but is not as macroscopically porous as cloth or paper. The essence of the achievement of Raghavan and his colleagues is that they were able to turn the hydrogel into a patch that can be folded like a regular fabric and torn like paper. To obtain the result, the researchers first soaked the hydrogel in acid, alkali, and other substances. Just like a mix ... >>

"At DNV, we are forecasting 2 TW of offshore installations. ... >>

All the chemical ingredients of life found on Enceladus 25.12.2022

Phosphorus, a key component of DNA and RNA molecules, has been discovered in the ocean of Saturn's moon. It is now known that Enceladus has all the basic elements that make up biomolecules - everything necessary for the emergence of life. Enceladus is one of the major moons of Saturn. Its surface is covered with a thick layer of ice, from the faults of which geysers are knocked out from time to time, indicating that there, at a depth, there is a fairly large ocean of liquid water. This makes Enceladus one of the most promising places to look for extraterrestrial life. This possibility is also indicated by the analysis of its water. Both methane and more complex organic molecules appear in it. Over the years of research, compounds of hydrogen and oxygen, carbon, nitrogen and sulfur have been found in the geysers of Enceladus - almost all the ingredients that make up biomolecules. And recently, the last element was added to this list, phosphorus, which serves as a key component of nucleic acids. This was announced by Yasuhito Sekine, who spoke last week ... >>

Smart watch with a living organism inside 25.12.2022

Scientists at the University of Chicago have come up with an unusual solution to the problem of changing gadgets too often and creating electronic garbage profusely - they have created a smart watch, which is provided by mucous - the easiest organism to feed and care for, almost like a Tamagotchi. The solution even allows you to establish an emotional connection with the smart watch. The use of a conductive protozoan organism - the plasmoid slime Physarum polycephalum - made it possible to create a smart watch that works only if the body in the body is healthy and supplied with food. In fact, the watch is a kind of simple cyborg with interconnected living and inanimate parts. It is expected that the presence of a living organism in electronics will prevent people from mindlessly changing gadgets at will. Irresponsible consumption leads to an increase in the volume of electronic waste on the planet - 40 million tons are added annually. The study of how a living device affects the behavior of l ... >>

hypoallergenic poplar 24.12.2022

The researchers have edited the genes of the trees so that in the spring they produce only "hairless" seeds that do not cause allergies. Selective breeding of plants is very broad and is aimed at giving them new useful traits or enhancing certain qualities. For example, scientists change the size, appearance, nutritional value, yield, resistance to pests, heat, cold, salinity or drought. As a rule, such work is carried out by selecting and crossing individual plants that have the necessary properties. However, the work is laborious and usually requires a certain amount of waiting time for the plants to mature. If the reproductive cycle of vegetable plants is only a few months, then for trees this period can include several years - this is a very long cycle, which significantly slows down the work of scientists. But it seems that in a new study, scientists from the University of Georgia solved two main problems at once - firstly, they reduced the reproductive cycle of topo ... >>

Iron Man Boots 24.12.2022

Scientists have invented Iron Man boots. They provide additional opportunities for walking. Engineers at the Biomechatronics Lab at Stanford University have created an automated exoskeleton that gives people a boost when they walk. Robotics expert Patrick Slade said: "Essentially, these are motorized shoes. By replacing the calf function with a motor, we can actually speed up the pace and help people walk easier and faster." The new exo-boot is worn over regular shoes, and the sensors are attached to the calf muscle using a brace and carbon fiber cables. When a person walks, a motor placed behind the shin pulls on a cable connected to the shoe, which allows the person to effortlessly (or with significantly less effort) lift the foot off the ground. However, these futuristic walking devices are far from universal - they first need to properly study the owner. The boots are equipped with an artificial intelligence unit that collects and analyzes data to understand ... >>

Sunswift 7 high-speed electric car 23.12.2022

A team of engineers from Australia are claiming a new world record for their Sunswift 7 electric vehicle. The solar-powered vehicle has been tested to cover 1000 km on a single charge in less than 12 hours. The Sunswift 7 electric car weighs only 500 kg. That's about a quarter of the weight of a typical Tesla car. To invest in such a small weight limit, engineers had to abandon the air conditioning system, ABS brakes, airbags, wipers and other features familiar to production cars. Instead, engineers focused on aerodynamic efficiency and rolling resistance. If the Tesla Model S has a drag coefficient of 0,208, then the Sunswift 7 has a drag coefficient of only 0,095. The team spent two years building the Sunswift 7 with the goal of setting a Guinness World Record and demonstrating the fastest solar-powered electric vehicle capable of driving ... >>

Created a battery that can last up to 400 years 23.12.2022

Mia Le Tay, a doctoral student at the University of California, Irvine, coated gold nanowires with manganese dioxide and an electrolyte gel similar to Plexiglas. She did it without any far-reaching plans - but the result was incredible. The student worked as a member of a group of researchers who studied the design of nanowires in batteries. She knew that the wires tend to break after a certain number of charge cycles. Typically, laptop battery nanowires last about 300-500 cycles. However, covering the sample with a hastily invented composition, she was surprised to find a dense film. The future scientist spent 10 thousand charge cycles - and did not notice signs of wear on the device. It looked promising, so Tai invited senior colleagues to evaluate the result. The group carried out 200 charge cycles within two months, and only after that it was stated that the coating, invented quite by accident, began to lose its properties. Scientists count ... >>

Deciphering the illegible handwriting of doctors 22.12.2022

Google is working with pharmacists to develop an artificial intelligence model for Google Lens that can decipher illegible handwriting, such as notes and prescriptions written by doctors. The company showcased the feature during its annual conference in India on Monday. Users need to either take a photo of the recipe or download it from the media library. Once the image is processed, the application will detect and highlight the medicines mentioned in the prescription. Google Lens is a multi-purpose artificial intelligence-based object recognition tool that can be used to identify products, plant or animal species, and translate. The Google Lens app could already be used to digitally transcribe handwritten notes, though the feature is still very dependent on how legible the handwriting is. To use the feature, you need to have the latest version of Google Chrome, as well as the standalone Google Lens app on An ... >>

Improved window insulation 21.12.2022

Physicists from the Polish Academy of Sciences have developed a method of thermal insulation coating for windows - stopping infrared radiation. Their idea allows to reduce the scale of heat loss through windows in winter. Savings on heating can reach several tens of percent, the developers of the solution calculated. Windows are often the weakest link in a building's thermal insulation. Even 10-50 percent of energy is lost because of them from heating apartments, - says Bartomie Witkowski, professor at the Institute of Physics of the Polish Academy of Sciences. How to make glass thin, transparent, strong, inexpensive - and save energy? The Polish team's method is to apply a permanent infrared filter to the glass. Professor Witkowska's team has developed a recipe for just such coatings, consisting of nano-doped zinc oxide. Window manufacturers can apply such infrared filters directly to the glass surface. But you can also make a transparent film, which by pasting ... >>

Mosquitoes are dangerous not only for their bites. 20.12.2022

Scientists from the University of North Carolina have discovered that mosquitoes can carry infections not only because of their bites. Pathogenic bacteria can also accumulate on their quotes. Scientists collected 79 adult female Anopheles coluzzii mosquitoes in Côte d'Ivoire. They were sent to the US to analyze the microbiome and the external surfaces of the body. As a result, fructobacyl was found on insect quotes. This means that insects visit flowers and beehives. A large number of staphylococci and two variants of rickettsia (Rickettsia bellii and Rickettsia typhi) that are dangerous to humans were also found. So far, no cases of infection have been documented. ... >>

Jeans sewing robots 19.12.2022

According to experts, in the foreseeable future, many manufacturing operations will be subjected to automation, which implies monotonous manual labor, but the big problem for the creators of robots is still their inability to handle flexible materials of arbitrary shape. Siemens engineers have found a way to train robots to sew jeans by treating the fabric with a special compound. Since 2018, relevant experiments have been carried out by Siemens and Levi's. The problem of automation in this industry escalated in the midst of a pandemic, when interruptions in logistics deprived American consumers of the opportunity to receive clothes in sufficient quantities from countries where core production has traditionally been concentrated in recent years. Robotic arms are difficult to process fabrics that can have different thicknesses and textures, as well as constantly changing shape in the process. Siemens began its experiments in this area with the creation of robots that can process everything ... >>

Wind turbine without blades 17.12.2022

Spanish startup Vortex Bladeless has developed a wind turbine that generates energy using vibration. Unlike analogues that use the energy of rotating blades to run a generator, the Vortex Bladeless windmill generates vibrations of the air hitting the structure. A three-meter pole, and this is exactly what the generator looks like, swings, as it were, on two large magnets located at the base of the structure. If the wind "pushes" the turbine in a certain direction, one of the magnets pulls it back. So the generator converts mechanical energy into electrical energy. By increasing the frequency of movements, the device converts energy into electricity. Therefore, from the outside, the white pillar may even seem alive. The wind generator is easy to maintain. Its base is made of pultruded carbon fiber; there are no rotating mechanisms and bearings in the design. The wear life of the material is 25 years. Among the advantages of Vortex Bladeless, developers highlight the easy adaptation of the turbine ... >>

Invented a way to prevent fogging glasses 16.12.2022

Scientists from the Swiss Higher School in Zurich used nanotechnology to stop the process of liquid condensation on glass. The innovative technology consists in creating a special film consisting of two layers of gold and a layer of titanium oxide between them. A thin (about 10 nm) coating on the glass provides a temperature increase of up to +8 °C. This helps prevent the condensation process from starting. Heating is carried out both at the expense of gold and titanium, but the latter also gives the structure additional strength. The photo-induced heating effect provides consistent and superior anti-fogging compared to uncoated samples, as well as impressive overall indoor and outdoor performance even in cloudy conditions. The extreme thinness of the coating, obtained using standard, easily scalable manufacturing processes, allows it to be integrated with other coatings, making it durable even on highly compliant substrates. Authors t ... >>

Coffee can improve the performance of semiconductors 15.12.2022

An ingredient found naturally in coffee can make semiconductors work faster, according to a study by the Institute of Advanced Industrial Science and Technology (AIST) in Japan. The researchers formed a thin layer of caffeic acid on a gold electrode inside an organic semiconductor through a process known as vacuum deposition. This reportedly made it possible to increase the current in the semiconductor by up to 100 times, which was measured using a process called the Kelvin probe method. According to the study, after applying a thin layer of caffeic acid to the electrode surface, the caffeic acid molecules spontaneously lined up on the electrode surface, allowing the current to flow faster. While this doesn't mean you can spill coffee on a mobile workstation to speed up render times, Japanese scientists believe this breakthrough could have some practical applications. Among them is the development of fully sustainable organic ... >>

Mining installations will heat greenhouses with tulips 14.12.2022

In a gigantic greenhouse near Amsterdam, gardeners have decided to channel their energy from cryptocurrency mining to heat tulip greenhouses. The startup involves six bitcoin miners. This reduces the dependence of farmers on the price of gas or electricity for heating. The servers of the mining rigs are powered by solar energy from panels located on the roof of the greenhouses, which significantly reduces energy costs. “We believe that this way of heating our greenhouse and also earning bitcoins is a win-win situation,” said Danielle Conning, owner of a huge flower garden. De Groot, 35, who mines cryptocurrencies in a flower garden, sees the Bitcoin-tulips collaboration as the perfect solution. It is a zero-carbon green operation. We are really improving the environment," the miner notes. He also sells tulips online through BTC, a startup called Bitcoinbloem. The Netherlands is a member of the EU. In the eurozone, ... >>

The sleep of babies 14.12.2022

Consultant neurologist Topun Austin of the University of Cambridge has found out why babies sleep a lot in a new study. The researchers took a new approach for experiments - they created a special hat, where they built in light sources and sensors. This helped to measure the blood circulation in the children's brains on the principle of a pulse oximeter attached to a finger. This method had been used before, but it required a cap with electrodes attached to it. As part of the new study, the experts used 12 tiles placed in a hat and connected to a computer with a single cable. In the end, they got a brain image 10 times better than the fiber-optic cable system they had used before. It turned out that infants are characterized by a cyclical passage of two phases of sleep: active, when the children are mobile, and calm, when the child remains motionless. Scientists recorded the work of the brain of newborns, and also monitored their behavior, using ... >>

Found a link between fear and alcohol addiction 13.12.2022

Studying the features of remembering terrible events, scientists from Linkoping University have identified an enzyme that affects anxiety and addiction to alcohol. Certain areas of the brain are especially important for processing fear-related memories. For example, the amygdala, which is activated in case of danger and cooperates with the prefrontal cortex. All of them start the process of regulating emotions. "We know that the network of nerve cells connecting the frontal lobes to the amygdala is involved in fear responses. The connections between these brain structures change in people with post-traumatic stress disorder and other anxiety disorders," said Estelle Barbier, study leader and associate professor at the Center for Social and Affective Neuroscience (CSAN) and the Department of Biomedical and Clinical Sciences (BKV) at the University of Linköping. However, the molecular mechanisms involved remained unknown for a long time. In a new study, scientists have found and analyzed the protein PRD ... >>

Electricity generation during wood drying 13.12.2022

By working with the fine details inside a tree, Swedish engineers have come up with an interesting new way to harvest electricity. This technology takes advantage of the natural processes that already occur when wood is dried, but overloads it to provide enough electricity for LEDs and other small devices. The study, led by nanoengineers at the KTH Royal Institute of Technology, focuses on the sequence of events that occur when wood becomes wet and then dries out. This is called transpiration and occurs in all plants as water passes through them and then escapes, actually producing a small amount of bioelectricity. Previous attempts to capture and use this electricity have been made difficult by low power, but the authors believe they have solved this problem by redesigning the walls of wooden cells. With a new treatment using sodium hydroxide, the team was able to create highly porous versions with pain ... >>

Algae will help extract gold from hot springs 12.12.2022

Researchers at Japan's Water and Earth Science and Technology Agency of Japan (JAMSTEC) and major engineering company IHI said they have found a way to isolate gold from hot spring water. Molten gold is found in magma at great depths below the Earth's surface. It is believed that this precious metal seeps into superheated hydrothermal water, slowly rises to the surface and hardens to form veins in the rock. Researchers believe that hot spring water may contain gold. They noted that cyanobacteria, also called blue-green algae, can be used to isolate the metal. According to them, algae absorb gold, separating it from chlorine and other elements. The group processed the seaweed into sheets, which they then soaked for seven months in a hot spring in Akita Prefecture in northern Japan. According to members of the group, up to 30 g of gold can be obtained from one ton of such sheets. On the largest ... >>

Discovered a new way to preserve vitamins in food 12.12.2022

Boiling, freezing, drying foods and many other factors destroy vitamins. Therefore, such food becomes less useful. Scientists from the Massachusetts Institute of Technology have developed a new way to fortify food with vitamin A. This will help improve the health of millions of people around the world. In a new study, they showed that encapsulating vitamin A in a protective polymer prevents the nutrient from being destroyed during food preparation or storage. Scientists plan to include such vitamins in flour or bouillon cubes. "We wanted to check whether vitamin A can retain its effect during cooking, and whether it will be destroyed under the influence of various factors," said Anna Jaklenek, the author of the study. To protect the vitamin from degradation, the scientists mixed it with a polymer to form particles 100 to 200 microns in diameter. They also coated them with starch to prevent sticking. Scientists have included these encapsulated particles in flour and broth. ... >>

Pheromones against crop pests 11.12.2022

The main harm to agriculture is caused by a butterfly called cotton scoop. It devours about 1/5 of all crops grown, but scientists from Lund University have figured out how to deal with it. Insect females can attract mates in complete darkness without any sound signal and at a distance of hundreds of meters using sex pheromones. Males track the smell of these chemical signals and mate with females, who then lay eggs. After that, hungry larvae hatch, destroying crops. "We can use artificial pheromone compounds in the field that will spread all over the air and override the original signal from a real female," explained Hong-Lei Wang, a researcher on the pheromone group at Lund University in Sweden. This sheer sheath of sexual odor makes it harder for males to find females and mate, and so the insect population is declining, meaning there are fewer pests in the area that can wreak havoc. ... >>

Moving objects with sound 10.12.2022

University of Minnesota researchers have discovered a new method for moving objects using ultrasonic waves. The research opens up opportunities for using touchless manipulation in industries such as manufacturing and robotics, where devices do not need an on-board power source to move devices. Although it has been previously demonstrated that light and sound waves can manipulate objects, the latter have always been smaller than the wavelength of sound or light, no more than a millimeter or even a few nanometers. A team at the University of Minnesota has developed a method to move larger objects using the principles of metamaterial physics. Metamaterials are materials that are artificially made to interact with waves such as light and sound. By placing a pattern of metamaterials on the surface of an object, the scientists were able to direct the sound in a certain direction without physically affecting it. "We have known for a long time that waves, light and sound, can manipulate ... >>

Smallest mobile life form created 10.12.2022

In a groundbreaking study, Japanese researchers at Osaka Capital University have created the world's smallest mobile life form. They introduced seven bacterial proteins into a synthetic bacterium. Eventually, she was able to move on her own. As the biologists explain, the study provides a better understanding of evolution and the origin of organisms' mobility. For the experiment, scientists used a synthetic bacterium syn-3. A completely artificial life form was created 12 years ago when scientists created a microorganism from a synthetic chromosome consisting of four chemicals. Then other researchers added the syn3 genome to the organism, which allowed it to grow and divide. However, he remained motionless. As part of a new study, scientists have introduced seven genes encoding proteins and "responsible" for the swimming functions of the Spiroplasma bacterium. This is a small natural organism in the form of a long spiral. As a result, syn3 also changed its usual round shape and became similar to Spiroplasma. Also ... >>

Fitness bracelets for cows 09.12.2022

The use of smart technologies to monitor the health, reproduction, location and environmental conditions of cattle can contribute to food safety and supply chain efficiency, but this monitoring increases energy costs for an already high industry. To combat this, scientists have developed a wearable sentient device for cows that captures the kinetic energy generated by even their slightest movements and uses it to power smart ranch technology. “On a ranch, monitoring information about the environment and health of cattle can help prevent disease and improve efficiency in breeding and pasture management. This information can include oxygen concentration, air temperature and humidity, amount of exercise, reproductive cycles, diseases, and milk production. "explained co-author Zutao Zhang, an energy researcher from the Southwestern Wu ... >>

Mars helicopter Ingenuity sets altitude record 09.12.2022

The Mars helicopter Ingenuity, which has been on a mission to Mars for more than a year, recently set a record for the highest flight altitude on the red planet. He managed to climb 14 meters. The helicopter was able to climb to a height of 14 meters and beat its own record of 12 meters. The helicopter was able to reach this level three times during the mission to Mars. Prior to this, Ingenuity had undergone a major upgrade that allowed it to avoid hazards during landing and use digital maps to navigate. With a height of about 48 centimeters and a rotor span of about 1,2 meters, Ingenuity arrived on Mars in mid-February 2021 with the Perseverance rover. In the summer of 2021, Ingenuity made its longest flight, lasting over a kilometer. This was the tenth drone launch. And the recent high-flying record-breaker was the thirty-fifth successful helicopter launch. ... >>

Cultivation of GM tomatoes approved for cancer, diabetes and dementia 07.12.2022

Tomatoes of an unusual purple color were developed in the UK. They owe their shade to snapdragon - and he also gave the fruits a large amount of anthocyanins that are healthy for health. Work on the creation of an unusual vegetable lasted for 14 years. The task of scientists Cathy Martin and Eugenio Boutelli from the John Innes Center in Norfolk, England, was to obtain tomatoes with high levels of anthocyanins. Anthocyanins occur naturally in many fruits and vegetables with red, purple, or blue flesh and skin, such as blueberries, strawberries, eggplant, and red cabbage. However, in their work, British breeders preferred to use garden flowers called snapdragons. By incorporating their genes into the DNA of tomatoes, scientists have obtained fruits with unusual properties. Due to the high level of anthocyanins, purple tomatoes have twice the shelf life of red varieties. Also, the miracle of selection is less susceptible to fungi. Anthocyanins may also have health benefits. Issle ... >>

Laser satellite communications 07.12.2022

With the help of a new satellite, developed by engineers from the Massachusetts Institute of Technology (MIT), a new record for data transmission between satellites and the Earth has been set. The TeraByte InfraRed Delivery (TBIRD) terabit infrared transmission system used lasers to transfer huge amounts of data at speeds up to 100 gigabits per second (Gbps). This data rate is much faster than most sky-to-ground connections. For example, SpaceX's Starlink satellite internet offers premium customers speeds of up to 500 Mbps. And the data transfer rate between the Earth and the International Space Station reaches around 600 Mbps. This makes the TBIRD system 200 times faster. The main difference of the new system is the method of data transmission. While most satellites communicate with ground stations using radio waves, the TBIRD system uses laser light. It can transfer 1000 times more data in one session. ... >>

Empathy and synchronous oscillations of neurons 06.12.2022

Biologists from the South Korean Institute of Basic Sciences have discovered a basic neural mechanism that allows you to feel empathy. A study in mice showed that synchronous neural oscillations in the right hemisphere of the brain help the animals perceive and share each other's fear. Scientists believe that people have similar reactions. Empathy is not unique to humans; many mammals exhibit similar behavior. A classic experiment in which empathy is shown in animals is called "fear of the observer." During the experiment, one of the mice is subjected to electric shocks, the second - watching this through a transparent screen. Previous studies have shown that the observer shares a sense of fear with the victim. This is manifested in the fading of the animal in place. In the new work, the researchers combined this classic experiment with optogenetic studies. The study showed that when the "observer" experiences fear in the front waist ... >>

Triatomic ultracold gas 06.12.2022

A group of Chinese scientists from the University of Science and Technology has created the world's first dense ultracold gas from triple atomic molecules, opening up numerous research opportunities for quantum chemistry. The researchers managed to create an ultracold gas from a mixture of sodium-potassium molecules and potassium atoms. Its temperature was extremely close to absolute zero, equal to -273,15 degrees Celsius. Chemistry is a process that can, in fact, be defined by quantum mechanics, but the quantum effects themselves are technically difficult to observe because the temperatures of chemical reactions are relatively high. Therefore, scientists have tried to slow down and cool these particles in order to clearly see the rules behind our universe at the micro level. According to the researchers, the next experimental challenge is the preparation and control of ultracold gases from triatomic molecules with a greater degree of freedom. These results may find applications in the future in quantum information processing and quantum measurement. ... >>

Night light can lead to excess weight 05.12.2022

Turning on the lights at night can affect your meal schedule and add a few inches to your waistline. According to Ohio State University researcher Laura Fonken, mice that were exposed to low light at night gained 50 percent more weight over an eight-week period than mice that spent their nights in total darkness. "In many ways, our society is now running on a 24-hour schedule," Fonken said. These results suggest that such a schedule may affect metabolic function, leading to weight gain. Hormones that help metabolism affect people exposed to light at night, Fonken said. Night light could reduce the amount of these hormones in mice, and together with a malfunction in the internal clock of mice, could cause them to gain weight. Mice are nocturnal, so they usually eat at night. But mice living in dim conditions ate 55 percent of their food during the day, compared to mice in standard conditions. ... >>

Airplanes will allow the use of mobile devices 05.12.2022

In its updated digital strategy, the European Commission has proposed defining 5G frequencies that will enable the use of phones and other connected devices during flights. In practice, the solution will allow airlines to allow customers to make and receive phone calls and text messages, as well as use data in the same way they do on the ground. The service will be provided using special network equipment called pico-cell, which connects the aircraft's on-board system to the ground via satellite. "The sky is no longer the limit when it comes to the opportunities offered by ultra-fast, high-bandwidth communications," Thierry Breton, European Commissioner for the Internal Market, said in a statement following the announcement of the European Commission's proposal. The decision of the European Commission does not mean that the use of phones on the plane will be free. Cells and airlines will most likely charge a special rate since the connection is ... >>

Computer games for dogs 04.12.2022

If your dog is tired of playing catch-up and tug-of-war, he might be more interested in video games! Hong Kong-based startup Joipaw has developed a series of touchscreen games designed to keep our furry friends' minds active. The founders of the company hope that video games will bring many benefits to dogs and help prevent a type of dementia known as cognitive dysfunction syndrome (CDS) in dogs. Dersim Avdar was inspired to create video games for dogs by his own dog, which he adopted in May 2021. The active dog quickly lost interest in puzzles and toys filled with treats and became restless, tearing up furniture and shoes of his owners and going to the bathroom on the floor of the apartment. The man and his wife quickly realized that these were all symptoms of separation anxiety, and that Kavet (dog's name) needed extra stimulation when the owners left the house. Then Avdar read a study from the University of Veterinary Medicine in Vienna, in ... >>

Zero Yield Aviation Fuel Production 04.12.2022

An interdisciplinary team of researchers at Worcester Polytechnic Institute (WPI) has developed a potential breakthrough in sustainable aviation: a zero-fuel recipe for aircraft that extracts carbon dioxide (CO2) from the air. Led by Jagan Jayachandran, Associate Professor, Department of Aerospace Engineering, and Adam Powell, Associate Professor, Department of Mechanical and Materials Engineering, the work is helping to address the urgent challenge of climate change. According to the International Council for Clean Transportation (ICCT), aviation is responsible for approximately 2,5% of all global greenhouse gas emissions and this figure is expected to rise. "As aviation grows, so will industrial emissions," says Powell. "We need to think outside the box and look at sustainable materials that will contribute to a long-term solution to reduce the transport sector's carbon footprint." Through modeling and computational analysis, Jayachandran and Powell developed a formula for a fuel consisting of ... >>

Positioning system without satellites 03.12.2022

Scientists from the Delft University of Technology in the Netherlands have created a new positioning system powered by cellular networks. Traditional GPS technology has many limitations and errors, such as a deviation in position determination of tens of centimeters and a long search for a location. Considering all the disadvantages of the modern system, scientists proposed to make a more accurate and faster navigation service that will use mobile communication stations. “The technology can become part of the next generation cellular network,” the authors of the project noted. “Global positioning systems such as GPS, Glonass and Galileo are widely used for applications such as navigation, but they do not always work well in densely populated urban environments due to buildings interfering with the direct line of sight of the satellite. As in the case of using satellite systems, the development of scientists is based on an accurate measurement of the time of arrival of radio signals. But the novelty uses the signal of the times ... >>

USB type-C will become mandatory for a number of devices such as mobile phones, tablets and e-readers, digital cameras and game consoles, headphones and speakers, wireless mice and keyboards and portable navigation systems. The rules will apply 24 months after they go into effect, likely in the fall of 2024. For laptops, there is a longer transition period of 40 months, which means that a common single device for laptops will appear in early 2026. "Having a charger that fits multiple devices will save money and time and help us reduce e-waste," said Czech Industry Minister Józef Sikella. ... >>

Relativistic contraction of the electric field 02.12.2022

Scientists at Osaka University's Institute of Laser Engineering have used ultra-fast electro-optical measurements for the first time to visualize the contraction of the electric field surrounding an electron beam traveling at near-light speed and demonstrated the generation process. According to the theory of relativity, to accurately describe the movement of objects flying past the observer at a speed close to the speed of light, it is necessary to use the "Lorentz transformation", which combines spatial and temporal coordinates. The Dutch physicist was able to explain how these transformations lead to self-consistent equations for electric and magnetic fields. Although the various effects of relativity have been proven many times with a very high degree of experimental accuracy, there are still parts of the general theory of relativity (including special relativity) that have yet to be revealed in experiments. Oddly enough, electric field compression is one of them: the modern pony ... >>

Reusable rocket engine 01.12.2022

China has made a breakthrough in its quest to develop reusable launch vehicles like SpaceX's Falcon 9. Engineers conducted the first hot test of a 130 ton engine. The test involved shutting down and re-igniting the engine, a process necessary to control how and where the rocket stages return to the ground. The engine was tested by the Aerospace Engine Academy in Xi'an, a subsidiary of the China Aerospace Science and Technology Corporation (CASC), the country's top space contractor and manufacturer of the Long March rocket family.

Charging gadgets with vibration from walking 30.11.2022

Japanese scientists from Osaka Capital University announced the creation of a high-performance and compact vibration energy collector capable of charging gadgets worn by people while walking. The size of the energy collector created by scientists is only 2 cm in diameter, the press service of the university reports. It is noted that this development, called MEMS (microelectromechanical system with piezoelectric vibrational energy), is approximately 90 times more efficient than other similar developments. The secret to this is the use of a U-shaped metal component called a dynamic magnifier that amplifies the vibrations that the MEMS converts into electricity. The dynamic magnifier made it possible to improve the generation of electricity without increasing the size of the device. MEMS is based on the use of the piezoelectric effect, a phenomenon in which certain types of materials produce an electrical charge or voltage in response to applied pressure. ... >>

Bread with invisible fibers will improve well-being 30.11.2022

Researchers at Australia's RMIT University have teamed up with technology company Microtec Engineering Group, which supplies starch processing equipment, to develop a fiber-digesting product.

Electricity from the snow 29.11.2022

The authorities of the Japanese city of Aomori intend to conduct a technical experiment to generate electricity using snow. Specialists will transport the snow collected during the cleaning of the streets to a pool located in one of the city's closed schools. Refrigerant pipes will also be placed inside. It is assumed that due to the temperature difference, a convection flow of refrigerant will be created, which will be able to rotate a turbine that produces electricity. Professor of the Tokyo University of Electrical Communications Koji Enoki emphasized that the efficiency of this method can be noticeably higher than using solar panels. At the same time, the use of snow is a more environmentally friendly way to generate electricity. ... >>

A new method for determining the age of complex deposits 29.11.2022

Researchers from Lanzhou University and the Qinghai Salt Lake Institute of the Chinese Academy of Sciences have made a new breakthrough in the field of luminescence dating. The method proposed by them is designed to determine the age of complex deposits in arid regions, which often causes difficulties for geologists. Optically stimulated luminescence (OSL) is one of the luminescence dating methods for determining how long ago mineral grains were last exposed to sunlight or heated. The OSL method has found wide application, however, it is not always suitable for determining the age of complex deposits. According to Li Guoqiang, a professor at the Institute of Resources and the Environment at Lanzhou University, a team of scientists spent seven years developing the innovative method, and its effectiveness has been verified. Alternately applying the new OSL method and radiocarbon dating, the researchers determined the age of proluvial deposits in the territory ... >>

Purifying water with eggs 28.11.2022

Found an unusual way to purify water from microplastics. This will help to get rid of the main environmental problem - the lack of drinking water. You can purify water at home. If suddenly it was not in the tap, and you got it somewhere on the street. Probably, the problem of acute shortage of drinking water on a planetary scale will soon be solved. And chicken eggs will help in this. The idea arose by chance. American chemist Craig Arnold was sitting at a dinner meeting of colleagues at Princeton University and began to examine the bread in his sandwich. Then he thought that the structure of this bread could be used in an airgel to filter water. Arnold and his assistants then began experimenting with bread recipes with extra carbon. The first samples of airgels did not have the necessary durability. Then the experiments continued with individual ingredients. And finally, there was an unexpected discovery: egg white with a little added carbon showed the necessary results. Test for now ... >>

Artificial retina developed 27.11.2022

Researchers at University College London have tested cells from young people with Usher syndrome, a rare genetic disorder. Cells have been reprogrammed to form stem cells that can recreate any human cell. In this way, scientists forced seven types of cells to fold the pattern, in fact, creating a mini-retina capable of capturing light. It turned out that Mueller cells, which cross the retina and provide energy to the eyes, play an important role in this process. According to Jane Sowden, a professor of developmental biology and genetics at the Institute of Child Health at the University of California, growing a "mini-retina" in the laboratory is indeed a breakthrough in the field. Scientists have recreated a mini-retina from stem cells for three children suffering from Usher's syndrome. The scientists realized that Muller cells were the main problem - they were damaged and literally "died" due to a genetic error. In total, it was analyzed ... >>

New unit of measure - kettabyte 27.11.2022

The world has come close to the largest existing unit of measure for the amount of data. Therefore, new prefixes have recently been added to the International System of Units of Measurement. They say that they will last for several more decades. For the first time in over 30 years, new terms have been officially added to the International System of Units (SI). Four new prefixes - ronna, quetta, ronto and quecto - now signify the largest and smallest numbers. The SI system uses prefixes to conveniently indicate the number of zeros in a measured unit. For example, a value of 649 million bytes with this prefix becomes a convenient 649 megabytes. Today, the amount of data created and consumed around the world is measured in zettabytes (add 21 zeros). After that there is another big one yottabyte, or 24 zeros after the digit. By the 2030s, the world is expected to generate one yottabyte of data per year. This amount of data, recorded on DVD, will last all the way to Mars. At the General Conference on Weights and Measures ( ... >>

Invisible car speakers 24.11.2022

Korean LG Display showed a new development for cars, a very thin Thin Actuator Sound Solution speaker, which the company called "invisible". Due to their modest size and low weight, such speakers can be placed in the most unexpected and previously inaccessible places, hiding from the eyes as much as possible. Although compact, the Thin Actuator Sound Solution vibrates to deliver rich, three-dimensional sound. LG managed to reduce the size and weight by removing the voice coil, magnet and other components of traditional speakers. The Actuator Sound Solution uses a so-called film exciter: thanks to it, the device is able to transmit vibration to surrounding materials. Speaker dimensions - 150 millimeters high and 90 millimeters wide, which is slightly larger than the size of a regular passport. The thickness is only 2,5 millimeters, and the weight is 40 grams. This will allow manufacturers to embed an innovative speaker that does not need to be played in almost any part of the cabin. For example ... >>

Fertilizer from the waste of lactic acid bacteria 24.11.2022

Researchers from the University of Cattolica in Piacenza (Italy) have developed a new fertilizer from the waste products of the production of lactic acid bacteria. Lactic acid bacteria are a group of microorganisms capable of fermenting various substrates. In this way, they create numerous products of interest to the agricultural and industrial sectors. Lactic acid bacteria are widely used in foods and nutraceuticals. Usually, for this they are cleaned by special installations, after which several thousand tons of waste are generated in Italy alone. Researchers have used this waste in the production of fertilizers and biostimulants in agriculture. Trials focused on greenhouse cultivation of tomatoes and lettuce. The results showed that thanks to the waste from lactic acid bacteria, it is possible to reduce the amount of chemical nitrogen fertilizers by 30%, without reducing production. Also, new preparations have improved some physiological properties of plants. Scientists also ... >>

The cause of the magnetization of the Universe is found out 23.11.2022

The "cosmic strings" left over from the Big Bang may be responsible for the universe's magnetic fields. Astronomers aren't entirely sure how galaxies and clusters get their magnetic fields. In the early stages of the development of the Universe, before the appearance of the first stars and galaxies, the cosmos was electrically neutral. Neutral gas cannot generate magnetic fields on its own, so the universe somehow had to create a magnetic field. Once the universe had this initial germinal magnetic field, it could amplify it as the evolution of the universe turned the neutral gas into an electrically charged plasma. But the source of the first magnetic field remained a mystery to astronomy for decades. Scientists offer perhaps the most exotic explanation for the source of the universe's original magnetic field: cosmic strings. Cosmic strings are theoretical objects that many astronomers believe formed in the very early universe. When our space was less than seconds ... >>

A useful variety of corn for popcorn has been developed 23.11.2022

Scientists at the University of Nebraska-Lincoln have developed a high-protein popcorn variety. It has a good effect on bowel function and improves health. Experiments began thirty years ago when researchers successfully inserted a variant of the opaque-2 gene into the maize genome. This made it possible to obtain a variety rich in lysine. Lysine is used in countries where people are suffering from hunger. But this gene changed the structure of corn grains so much that it was impossible to extract popcorn from it. Now everything has changed. Scientists have discovered fragments of the corn genome responsible for the characteristic popcorn texture. Over the course of several generations of maize, they crossed carriers of these genes with other varieties. The new varieties outperform today's most popular varieties in terms of nutritional value and taste. They have a beneficial effect on the human microbiome. When the popcorn from this corn is digested, the microbiome greatly increases the production of butyrate, a fatty acid. This acid improves health. ... >>

These competing companies will compete for a contract with the UK to launch an expedition to clean up the Earth's orbit from space debris as early as 2026. ... >>

Revolutionary water desalination method 22.11.2022

A team led by the King Abdullah University of Science and Technology (KAUST) has developed ultra-thin polymer-based membranes that remove salt from seawater more efficiently than anything else. Yu Han, a researcher at KAUST and one of the authors of the technology, explained that existing desalination techniques have many shortcomings. For example, the latest graphene-coated carbon nanotube membranes, which were supposed to be resistant to salt and powerful water flow, still turned out to be impractical due to difficulties in installation and use. Khan and his colleagues introduced an alternative to the world - membranes coated with triethynylbenzene monomer. This made it possible to form a surface with sub-nanometer-sized cells that let water through and retain salt. The membranes have already shown excellent performance in both direct and reverse osmosis. The team is currently working on improving mechanical strength and chemical resistance. ... >>

Super low sounds make people dance 21.11.2022

Rhythmic sounds at frequencies beyond the range of human hearing affect listeners. Experiments with the Canadian band Orphx showed that extremely low basses stimulate the audience to dance, although they are not perceived by consciousness. "Music is a biological mystery: it's not needed for reproduction, nutrition or survival, but why do people love it so much and love to move to it so much"? asks Daniel Cameron. Together with colleagues from the Canadian McMaster University, he explores the effect of music on our nervous system. In their new work, scientists have found that even ultra-low frequencies lying on the verge of hearing imperceptibly affect listeners, stimulating them to dance and move more actively. The impact of music on a person is unexpected and varied. Many of its aspects are related to personal experience and familiar culture, but others are universal. It is not for nothing that representatives of any peoples perceive the same melodic phrases all the same - let's say, as sad or invocative, triumphant. There are also for ... >>

Electricity behaves like water 20.11.2022

Researchers at the Massachusetts Institute of Technology have observed "electronic whirlpools" for the first time. Strange behavior occurs when electricity flows as a liquid, which can make electronics more efficient. Like water, electricity is made up of discrete particles, so you would expect them both to flow in the same way. But while water molecules are large enough to push each other and flow together, electrons are much smaller, meaning they are more affected by their environment than each other. However, it was envisaged that under ideal conditions—at temperatures close to absolute zero and in pure, defect-free materials—quantum effects should take control of their movement and allow them to flow as an e-liquid with the viscosity of honey. If scientists could use this, it could create more efficient electronic devices where electricity flows with less resistance. In a new study, a team at the Massachusetts Institute of Technology ... >>

Sweet makes ants more fun 20.11.2022

A team of zoologists from Austria found that ants show excitement after eating dessert. In this they are like us. Understanding the emotional states of animals is the key to the formation of ethical norms, but the study of the inner world of insects has always received too little attention. Austrian biologists decided to fix it. They conducted an experiment with ants, during which it turned out that these animals can experience something like an optimistic mood. First, the researchers trained ants to associate two scents with positive or negative reinforcers. They then mixed the two scents to gauge the reaction of the insects. It turned out that ants tend to associate a mixed smell with positive reinforcement, demonstrating optimistic behavior. If before that the subjects received sweet food, then their optimism increased. Moreover, even if there was more negative odor in the mixture or the ants were physically affected, they were still more ... >>

Giant star with magnetic clouds discovered 19.11.2022

Scientists at the Xinjiang Astronomical Observatory (China) studied the light from the extreme magnetic star HD 345439, determining its properties. One of its features is magnetized plasma clouds that periodically darken the light from the star, reducing its brilliance. HD 345439 is a helium-rich, massive magnetic star with very strong magnetic fields. It is about seven times larger and almost nine times more massive than the Sun. HD 345439 has longitudinal magnetic fields exhibiting periodic variability with an amplitude of about 2-3 kilogauss (kG), and the polar magnetic strength of this star reaches 10 kG. Such powerful magnetic fields can contribute to the accumulation of circumstellar material and form a dense disk. To explain the variability of magnetic stars, scientists have developed a model of a rigidly rotating magnetosphere (Eng. Rigidly Rotating Magnetosphere, RRM). It assumes that the plasma moving along the lines of force is subject to gravitational influence, which causes it to fall ... >>

Mushroom Skin Electronic Chip 19.11.2022

Researchers from the Johannes Kepler University analyzed the composition of the tinder fungus and concluded that it would be an excellent replacement for plastic polymers. According to scientists, the use of mushroom skins to make the basis of computer chips and batteries would facilitate their processing. All electronic circuits made of conductive metals must be contained in an insulating and cooling base called a substrate. In almost every computing chip, this substrate is made from non-recyclable plastic polymers, which are often thrown away at the end of the chip's life. Martin Kaltenbrunner and his team tried using mushrooms to create this base. For a long time they did not succeed, but then they started testing the skin of the mushroom Ganoderma lucidum (varnished tinder), and its properties turned out to be quite suitable for replacing polymers. The fungus, which usually grows on decaying wood, forms a skin to protect its mi ... >>

Fiber throughput record set 18.11.2022

Japanese scientists were able to set a new world record for the throughput of a single optical fiber. The record was set by scientists from the Japanese National Institute of Information and Communication Technology. They achieved a throughput of about 1,53 petabits per second (1 petabits is 1000 terabits). The achievement was made possible by encoding information at 55 different light frequencies (a technique known as multiplexing). This bandwidth is enough to carry all of the world's Internet traffic over a single fiber optic cable. ... >>

Efficient artificial photosynthesis 18.11.2022

A team of chemists has developed an artificial photosynthesis system many times more efficient than any current solution. It can produce ethanol, methane or other fuel. Through this process, we may soon be fueling cars. In nature, photosynthesis is carried out by several complex complexes and systems that are difficult to direct to perform other tasks. They take in water and carbon dioxide, break down molecules, and redistribute atoms to make carbohydrates. Over the production of methane instead of them, chemists have been fighting for decades. A group of scientists from the University of Chicago decided to add to the reaction something that is not found in natural photosynthesis - amino acids. It is based on metal-organic framework structures (MOFs), a class of materials made of metal ions bound by organic molecules. Then a layer was created from it, which became a surface for chemical reactions, and it was immersed in a solution with cobalt. Finally, amino acids were added. The result showed that thus ... >>

Short daylight hours affect mental ability 17.11.2022

Scientists have found that dim winter lighting aggravates cognition by reducing the connectivity of neurons in the brain. These conclusions were reached by scientists from the University of Michigan in the course of experiments with grass mice. They, like humans, are awake during the day and sleep at night. This allows a much more accurate comparison of these animals and humans compared to conventional non-diurnal laboratory mice. Professor Lily Yang and her team of researchers studied grass mice to understand how light modulates brain function and behavior. Two groups of rodents were kept under different conditions for a month. The first lived under dim light - 50 lux, as in a room. The rest - for 1000 lux, like in a supermarket. This model simulated seasonal changes in lighting in winter and summer. Then the mice had to go through the maze. The first group coped with the task worse. In rodents, the ligaments of neurons in the hippocampus of the brain have decreased by almost a third - it is responsible for memory. Also they were in the worst mood ... >>

Turning sand into fertile soil 15.11.2022

A Norwegian startup has invented a method by which, after spraying sand with liquid nanoclay, it turns into water-retaining soil. Every year, 12 million hectares of fertile land are lost due to desertification. The Desert Control solution turns sand into soil for plants in just 7 hours. Liquid nanoclay was invented in the early 2000s by Norwegian scientist Christian Olesen. It was she who was used by a Norwegian startup. When sprayed, it penetrates the sand, turning it into water-retaining soil where plants can sprout. "Our vision is to make the earth green again by stopping and reversing desertification and soil degradation. With our unique product, we want to turn degraded land and sand into fertile soil and at the same time reduce water consumption for green ecosystems by up to 50 percent," - note the inventors. Desert Control plans to primarily sell its nanoclay to the UAE, where deserts make up most of the ... >>

After the publication of the relevant report, Amazon was visited by representatives of the Federal Occupational Safety and Health Administration with a set of ... >>

Food is like a drug 14.11.2022

Donuts, pizza, cereals, sodas - all these foods are very tasty and also dangerous for our health. In a new study, scientists came to the conclusion that ultra-processed foods can be safely put on a par with drugs and cigarettes - they harm the body and cause addiction. A team of researchers led by University of Michigan psychology professor Ashley Giergardt, PhD, concluded that ultra-processed foods, which include chips, baked goods, candies, cereals, donuts, sodas and more, contain a huge amount of artificial flavors, canned food. All this makes them very tasty, but also high in calories, fat, sugar or salt, which increases the risk of obesity or the development of other diseases. As a result, scientists came to the conclusion that all this makes the "flavors" more like drugs, because they, in fact, are far from natural in texture and taste. According to Health Behavior Research Professor ... >>

Robospiders for sewers 13.11.2022

The Japanese company TMSUK has unveiled small spider-like robots that it believes will be useful in the study of sewer systems. They will crawl into narrow pipes and inspect them with a 360-degree camera. Moreover, TMSUK is even considering scenarios in which the works can even carry out repair work. Japanese engineers showed a prototype system for exploring hard-to-reach locations, or just a few six-legged robo-spiders measuring 21 by 25 by 28 centimeters and weighing about 3,5 kilograms each. Works are managed by an operator who can view video from cameras in real time, taking into account 360 degrees. The "eyes" of the robot spider, of which there are four, have LEDs and sensors so that the robot can assess what is happening around. It is noted that sending several robots into the sewer can provide not only an overview of communications, but also the ability to fix something: for example, one robot will lead others, the second will assess the area, and the third - something ... >>

information engine 12.11.2022

The highlight of the year was the development of the so-called information engine, fueled by information. The prototype engine did the job solely by calculation, without spending any energy on it. Unfortunately, this discovery works only in the microcosm. We all know about such a phenomenon as thermal noise. In the normal state, thermal fluctuations are random in nature and cannot do useful work. You can correct the situation with the help of feedback - information that could cut off the "braking" oscillations and fix the "working" ones. Then each time the engine would do only useful work, without spending energy on it in the form of fuel. The role of fuel in such a system would be played by information - this is a system for determining the perfect work and feedback that controls the engine. A group of physicists from the Simon Fraser University in Burnab (British Columbia) and the Institute for Fundamental Questions (FQXi) conducted an experiment in which a glass bead ... >>

Test tube beef steak 11.11.2022

Scientists have grown a juicy steak from a cow's cage in order to cook it later Scientists from Newcastle University's subsidiary 3D Bio-Tissues (3DBT) have been working on creating a steak from a test tube. In the course of the study, scientists were able to grow three small prototype steaks that are in no way inferior to natural ones in appearance and smell, without using vegetable substitutes and without exterminating cows. According to 3DBT Executive Director Che Connon, he and his team are very pleased with the results - the pieces of the grown fillet not only match the outwardly good juicy steak, but also have the necessary smell and characteristic crust during the preparation of meat. To create their innovative development, scientists used the cells of living cows - the biomaterial is taken using a painless biopsy. As a result, scientists consider the fact that not a single cow was harmed during the study to be another achievement of theirs. The cells are then placed in a special bioreactor. ... >>

Pregnancy changes the mother's bones 10.11.2022

Scientists at New York University found that pregnancy can change the mother's skeleton. A new study shows that even before fertility stops, the skeleton responds dynamically to changes in reproductive status. In addition, these results confirm the significant impact of pregnancy on the woman's body. During pregnancy, the mother's body can extract calcium from the bones, which reduces the mass, structure and density of the woman's skeleton. During the study, scientists studied the skeleton of seven macaques, four of which were females. As it turned out, the femurs of females are different from the femurs of males, and this can be explained by lactation and pregnancy. The bone composition of macaques that have been pregnant is affected by bone resorption during reproduction, but more research is needed to confirm this. ... >>

Seafood packaging material 09.11.2022

Scientists from the University of Siena (Italy) have come up with a way to make packaging material from shrimp shells and other marine animals. Such material will not be functionally different from plastic, and after use it can be used as a fertilizer. Researchers have found that chitin, found in the shells of marine animals, is a natural polymer. In combination with wood products (eg lignin) it obtains antimicrobial, antioxidant and photoprotective properties. Thus, by combining these materials, it will be possible to create a multifunctional and fully biodegradable packaging (for example, for products). According to scientists, their development is not only an environmental alternative to plastic, but will also help fisheries reduce waste. Currently, scientists are working on the creation of the first prototype. ... >>

When the maximum power mode is activated, the engine will operate at this indicator ... >>

Super strong rayon 08.11.2022

Chinese researchers have found a new way to create ultra-strong mulberry rayon, which shows significantly higher strength than the strongest natural silk. Silkworm silk is also widely used in biomedicine as a surgical material and in tests for tissue creation. Silk is a protein-based biopolymer with a unique combination of different physical properties. Silkworm silk has less strength than the strongest natural silk - spider web dragline silk, which makes up the main frame of the web. Scientists have tried to inject spider DNA into silkworms to increase the tensile strength of their silk. Researchers at China's Tianjin University selected common silkworms, which are more affordable and manageable, to produce rayon. Natural mulberry silk fiber consists of a main fiber coated with silk glue, ... >>

Firefly Shine Synchronization 07.11.2022

Scientists have figured out how the glow of fireflies synchronizes. According to a study by an international group of mathematicians, the synchronization of the glow of insects is based on the distance separating them from each other. Experts already knew that males of these insects use light signals to search for mating partners, while insects of the species Photiunus Carolinus turned out to be prone to encoding luminescence in their swarms. Therefore, the researchers had to experimentally decipher the model of their behavior. The scientists simulated the blinking of one individual, then expanded it to a pair, so they could compare the difference in blinking frequency. So, in a large swarm, changing the distance at which the fireflies could react to each other changed the order of the glow. By changing the distance between insects, the researchers were able to obtain different patterns of their blinking, among which were ripples or, for example, a spiral. ... >>

Canon EOS R6 Mk II Full Frame Camera 07.11.2022

quantum stopwatch 06.11.2022

Scientists at Uppsala University in Sweden have developed a new way of measuring time that doesn't require a specific starting point. This method is based on an experiment with Rydberg atoms - particles of hydrogen and alkali metals with electrons in a highly excited state. This state is achieved by exposing the substance to a laser beam, after which the electrons are greatly removed from the nucleus and the size of the atom increases significantly. It is the change in the position of the electron that can be used for the most accurate measurement of time. Therefore, scientists used the transfer of atoms to the Rydberg mill as a new "time scale". Experts measured the results of excitation of helium atoms by a laser, comparing the obtained data according to theoretical indications. "If you use a counter, you must define zero, and only from that moment do you start counting. The advantage of our method is that you do not need to start the clock - you just look at the interference string ... >>

EnCodec music format 06.11.2022

Meta, which owns Facebook, Instagram and WhatsApp, has unveiled a new AI-based audio compression method called EnCodec. It can compress audio 10 times better than MP3 format. The new method can be applied to real-time audio streaming, which can greatly improve voice quality over low-bandwidth connections, such as phone calls in areas with unstable connectivity. The method also works for music, so someday we will get really small music audio files with it. nCodec can compress audio 10 times more than the mp3 format at 64 kilobits per second without quality loss. Thanks to this, the file will take up 10 times less space on your hard drive with the same sound characteristics. The developers note that the neural network performs its task very well, and the human ear will not be able to catch the difference between the original and the recoded source. ... >>

Hearing restoration with butterflies 05.11.2022

A team of Australian researchers from Melbourne and Perth has developed an innovative device to repair the eardrums in patients with hearing impairments. Scientists have added silk to a ClearDrum middle ear implant that can grow a patient's cells. The implant looks like a contact lens from the outside. Silk, which easily changes shape, is ideal for the device, experts said. The researchers removed sericin, a protein found in silk, also known as silk glue. Then the protein was heated to a liquid state and used to create a device. The device must be surgically placed under the damaged eardrum. Subsequently, it becomes a platform for the growth of new tissue. If the damage is small, the device will dissolve some time after repair. With serious damage, it remains in the ear forever. ... >>

Hybrid offshore power plant 05.11.2022

One of China's four largest energy companies, State Power Investment Corporation (SPIC), has for the first time put into operation a hybrid offshore power plant - simultaneously powered by wind and solar energy. If the tests go well and the station has to weather storms and typhoons, the project will continue to grow with the prospect of deploying up to 42 GW of offshore hybrid capacity in the region. The peak power of the first two rafts with solar panels is only 500 kW. The solar energy generated on the rafts is fed to a transformer installed in the wind turbine tower. From the power substation of the wind generator, electricity is sent to the mainland by an underwater cable to consumers. The project of a hybrid offshore renewable power plant was developed by the Norwegian company Ocean Sun. This is the world's first practical implementation of the development. The Norwegians came up with the design of rafts and anchors so that they could withstand the impact of the elements without the consequences of the equipment. Next year the project plans ... >>

The Danger of Dirty Windows 04.11.2022

Scientists from the University of Birmingham called for washing dirty windows. They argue that windows can contain toxic contaminants and hide potentially harmful contaminants behind a film of fatty acids from food preparations that can be stored for long periods of time. Fatty acids present in cooking emissions are very stable and difficult to break down in the atmosphere. And when they hit a hard surface like a window, they create a thin, self-organizing and slowly accumulating film, and can only be gradually broken down by other chemicals in the atmosphere. Thus, the film will become rougher and draw out more water due to air humidity. In addition, harmful contaminants can enter the resilient crust, where they are then protected from degradation in the atmosphere. The fatty acids in these films are not particularly harmful on their own, but because they are not broken down, they effectively protect any other contaminants. ... >>

Sunny instead of Wi-Fi 04.11.2022

A team of scientists from Saudi Arabia has developed a solution that can use sunlight instead of traditional Wi-Fi. The smart glass system, being developed by scientists at the King Abdullah University of Science and Technology (KAUST), can modulate sunlight passing through it, encoding data into light waves that can be received and decoded by devices placed in the room. Using sunlight to transmit data allows you to create a more environmentally friendly type of connection when compared to conventional Wi-Fi or cellular communications. The system can be installed in glass windows of large buildings, such as offices. The solar-based communication system developed by KAUST specialists consists of two parts. A light modulator that can be built into the glass surface and a receiver placed in the room. A matrix made up of liquid crystal shutters can function as a filter for encoding signals in ... >>

Sleep learning secret revealed 03.11.2022

It is well known that in order to consolidate new information received during the day, you need to "sleep" with it. During the night, all knowledge and impressions will subside and be deposited in memory. A similar process is even reflected in folk proverbs and sayings. However, until now, scientists have remained a mystery of what exactly happens in the brain and how to explain this phenomenon. To unravel this mystery, researchers at the Pennsylvania State University (USA) conducted a series of experiments in which volunteers slept in the laboratory, and scientists recorded changes in their brain activity. As a result, based on these data, a computer model of the activation of neural networks during sleep was built. Scientists have found that as the brain goes through slow-wave sleep and rapid eye movement (REM) sleep, which happens about five times a night, one region of the brain, the hippocampus, "teaches" another region of the brain, the neocortex, with the information received during wakefulness. knowledge. Through this process, the new ephemeral and ... >>

Food sensors based on paper and graphene 03.11.2022

Korean scientists have developed new food freshness and temperature sensors. They are based on laser-induced graphene on environmentally friendly, biodegradable paper. Last year, about 78 percent of the plastic entering the environment is food packaging. Thus, the development of biodegradable bags, boxes and glasses for our food is the primary concern of people who are not indifferent to the problem of plastic pollution of the planet. Although several large companies have already released their lines of biodegradable packaging, including utensils and drinking straws, there is still the problem of monitoring the quality of food in such packages, that is, tracking the temperature and freshness of food. Most of today's food condition sensors are not biosoluble, so even when attached to eco-friendly packaging, they eventually become part of the plastic that pollutes the planet. However, now experts from Seoul ... >>

Insects can generate electricity 02.11.2022

An international team of scientists has found that swarms of insects can produce atmospheric electrical charges. Measurements showed that they give out as much charge as a thundercloud. It is noted that bees sense changes in electric fields in order to navigate to flowers. Static charges help pollen stick to them. And in this way, these insects can receive an electric charge when they fly through the air. "We have always looked at how physics affects biology, but at some point we realized that biology can also affect physics. We are interested in how various organisms use static electric fields, which are almost everywhere in the environment," the author said. a new study by Ellard Hunting of the University of Bristol and the University of Reading. The researchers placed an electric field monitor near the research hives and measured the changes as swarming began. It turned out that swarms of honey bees increased atmospheric electricity by ... >>

Numerous studies have linked video games to behavioral deterioration and mental health problems. The same study suggests that ... >>

Scientists have learned to erase memories 27.10.2022

Controlled sleep deletion of unwanted memories can help many people clear traumatic memories. Some information stored in our brain is not needed by a person, but it is impossible to forget it. Scientists were able to achieve a targeted removal of unnecessary memories. Scientists have been working for a long time to unravel the secrets of the complex system of the human brain. Recent research has brought them a little closer to this goal. The memory erasure theory was studied by a group of scientists from the University of York. They began by studying sounds that, during sleep, can enhance or, conversely, minimize the significance of memories. This approach can help many people living with traumatic memories. Scientists observed 29 people who participated in the experiment. For them, different pairs of words were shown on the monitor, with the first word always being an object, and the second showing some place or person.

Drone warns of tsunami 25.10.2022

In the northern Japanese city of Sendai in Miyagi Prefecture, an alert system has been introduced that uses drones to warn beachgoers of a tsunami threat. In the event of a tsunami warning, two drones that are in metal boxes near the beach will take off and issue "High Tsunami Chance" alerts. The devices are programmed to fly along the coast and call for beachgoers to evacuate. The local authorities started such a system after several officials died in the devastating 2011 tsunami while helping local residents evacuate after a tsunami warning was announced. Drones can also reach coastal areas where notifications from stationary centralized systems are not heard. Officials control drones thanks to a special network that can work even during natural disasters. Drones can be mobilized faster than helicopters and alert people at lower altitudes. ... >>

Women remember words better than men 25.10.2022

Norwegian researchers conducted a meta-analysis involving more than 350 people. He touched upon numerous scientific studies, dissertations and other works published in scientific journals. All of them concerned the differences between male and female memory in a number of ways. It turned out that women are better than men at remembering words and extracting them from their memory. True, this advantage was not too significant, but stable. Almost all scientific works have shown that women throughout their lives are better at memory for words than men. And if it weakens in old age, then the male memory weakens even more. What was interesting here was that the level of this advantage depended on the gender of the researchers. So, if the experiments were carried out by female scientists, then their female memory turned out to be stronger, and if by men, then less strong. The researchers note that until now, scientists have been mainly interested in men's ability to remember information, but ... >>

Edible sensor for food freezing control 23.10.2022

The new development of scientists will help sellers and buyers find out how many times the product has been defrosted and frozen. When we buy products, it is not always possible to say how strictly the conditions for their storage and transportation were observed. It is possible that they were repeatedly frozen before being sold, and this has a big impact not only on the texture, but also on the taste. Therefore, the sensor will soon be actively used, it will show the number of defrosts and freezes. The sensor is safe as it is made from edible materials such as table salt, red cabbage and beeswax. The device changes color when heated above a predetermined temperature from minus 50 to zero degrees. It is a galvanic nest filled with an electrolyte solution. This role can be played, for example, by a solution of table salt, grape or apple juice and other edible liquids saturated with salts. Depending on their set, the temperature sensitivity of the system changes. This g ... >>

Children learn to lie in order to live up to adults' expectations. 23.10.2022

"A good child always tells the truth" - that's what parents try to instill in their children in words, but in reality their actions sometimes contradict these moral principles. As a result, the child learns to be not an "honest simpleton", but a "polite liar", who is able, if necessary, to hide an unpleasant truth - after all, this way his chances will be praised more. "Truth is good" is too simple an attitude for a complex human society, and as it develops, the child begins to increasingly face the fact that he suffers more for the truth than for a lie. "I don't want this dress, it's ugly" - words that, being completely honest, can lead to severe punishment than polite gratitude, after which you can put the clothes you don't like in the closet. It is not surprising that children learn to lie from an early age, although we still know little about how this skill is formed and developed. Undoubtedly, it arises due to the inconsistency of the surrounding social environment, when in words parents assure ... >>

Plants on the desktop reduce stress 22.10.2022

Japanese scientists from Awaji University found that plants on the desktop help to calm down and reduce stress. In this case, the effect was observed from all species - cacti to dwarf trees. As part of the experiment, for 4 weeks, 60 office workers worked with plants on the table - bonsai, indoor palm, everia, kokedama and cactus. Their anxiety levels and heart rate were compared before and after the study. It turned out that the participants in the experiment experienced less stress. "Not everyone understands and uses the benefits of plants in the workplace. Therefore, we decided to test and provide scientific evidence for the recovery of the body in this case," explained study author Masahiro Toyoda. Levels of cortisol, the stress hormone, dropped an average of 10% when workers looked at plants. For the best effect, scientists note, it is necessary to carry out therapy by contemplating flowers for about 20-30 minutes a day. ... >>

Recorded the most powerful burst of energy in space in the time of observation 22.10.2022

The burst was named GRB 221009A and was first detected by the Fermi Gamma Ray Space Telescope, a joint project between NASA and the US Department of Energy, as well as the space agencies of France, Italy, Japan and Sweden. Gamma-ray bursts are large-scale cosmic bursts of gamma rays in the electromagnetic spectrum that can result from various phenomena, such as the death of large stars. Such events are the brightest electromagnetic events in the Universe. The recent gamma-ray burst recorded on October 9 was reported by NASA scientists working with the Fermi Gamma Ray Telescope and the Neil Gerels Swift Space Observatory. Astronomer Phil Evans of the University of Leicester said the latest gamma-ray burst "is clearly the brightest GRB we've seen in X-rays." ... >>

Climate change could cause permanent allergies 21.10.2022

Experts from the Italian Society of Allergology, Asthma and Clinical Immunology (SIAAIC) warn that global warming may lead to the progression of hay fever, which now lasts one to two months. According to experts, climate change will lead to a 200% increase in pollen produced by plants within a few decades. This causes severe and prolonged allergy symptoms. The increase in temperature, allergists explain, determines the distribution of pollen of different types, which usually bloom in spring and summer, even in autumn. According to a study published in the journal Nature Communications, the critical season for allergies will start up to 40 days earlier in the spring and will be extended by three weeks in the fall. “Already now we are not only registering complaints of allergy sufferers in the spring. And the warming will lead to the fact that many of them will suffer from pollinosis almost all year round,” said SIAAIC President, Professor of Respiratory Diseases at Univers ... >>

Ultra-precise clock synchronized at record distance 20.10.2022

Chinese physicists have managed to perfectly synchronize the work of two clocks at a record distance of 113 kilometers. Potentially, this will allow for incredibly accurate physical research - and not only. Since 1967, one second is officially equal to 9192631770 periods of electromagnetic radiation, which causes the electrons in the cesium-133 atom to change their state. Today, optical clocks use even more precise "ticking" of chemical elements such as strontium, rubidium, calcium and ytterbium. The main requirement is that the atoms be insensitive to magnetic, electric and electromagnetic fields, that is, not subjected to any external influence. Last year, two independent teams of physicists from the University of Colorado and the University of Tokyo created a new high-precision optical lattice clock. For their work, they shared a $3 million prize from the Breakthrough Prize jury. This made it possible to create atomic clocks that would desynchronize by ... >>

Ecological way to recycle old solar panels 20.10.2022

One of the problems of renewable energy energy is the processing of elements of systems that have served their time. In particular, this applies to solar panels used around the world. By 2023, about 1,5 million tons of photovoltaic waste is expected to be generated annually in China, 1 million tons in the US and 145 tons in Australia. A study by scientists from the University of New South Wales (Australia) proposes a cost-effective and environmentally friendly way to recycle solar panels, which should help cope with the growing volume of photovoltaic cells. The process includes dismantling the solar panels, removing the aluminum frame, shredding the light receiving cells, and using electrostatic separation to collect valuable materials such as silver and copper. Dr. Pablo Diaz, one of the authors of the work, said that the study showed the possibility of launching a small enterprise capable of processing up to 1000 tons of spent solar cells per year. ... >>

Raising a dog is like raising a child. 18.10.2022

Most of the previous research has focused on the influence of past experience or home environment on the formation of the character and habits of the pet, while little attention has been paid to the personality of the owner and his approach to raising the dog. Now, researchers are increasingly trying to find a way to capture the relationship between the behavior of the dog owner and the behavior of his pet in order to evaluate our contribution to the formation of the character of the animal. Surprisingly, research on the relationship between humans and dogs is in many ways similar to work in the field of human psychology. Just as the behavior of parents has a huge impact on the development and behavior of the child (including parameters such as social activity, psychological stability and even labor productivity), the behavior of the owner turned out to be an equally significant parameter in the development and formation of the dog's personality. Scientists conducted a survey of 48 dog owners, asking them the details of raising a pet. Using the data obtained from the interviewed distribution ... >>

Caterpillar saliva against plastic 17.10.2022

Today, the world is literally suffocating under mountains of plastic: river banks are littered with perennial rubbish, and entire garbage "islands" float in the oceans. Existing waste recycling methods cannot cope with the amount of plastic produced, so scientists are constantly looking for new ways to dispose of it, including in the saliva of moth caterpillars. People produce about 400 tons of plastic a year, and despite all efforts to reduce its use and recycle, a huge amount of undecomposed garbage ends up in landfills. About a third of it is polyethylene, a tough plastic that takes five to 15 years to completely decompose without human intervention. Previously, experts conducted studies on the effect on polyethylene of various microorganisms that can accelerate its decomposition. However, in all cases it was about months of processing. But now scientists have discovered an animal that can literally digest a plastic bag in just a few hours. "The Devourer ... >>

Found a hormone that restores heart tissue 14.10.2022

Scientists at Michigan State University were able to prove in a study that the neurotransmitter oxytocin can help heal damaged tissue in the heart after a heart attack. The recovery mechanism is based on the fact that the cells of the epicardium, the outer transparent membrane of the heart, can migrate inside the heart muscle. There they turn into cardiomyocytes, that is, muscle cells responsible for the contraction of the heart, which the body cannot easily replace in case of damage. In the epicardium, there are special cells that can transform into a kind of stem cells that can form heart muscle tissue. However, under normal conditions, this effect in humans cannot compensate for the massive death of cardiomyocytes that occurs during a heart attack. This is what zebrafish are capable of, which can completely regenerate various organs, including the heart, which restores three-quarters of its lost cells. ... >>

Potato bacterium antibiotic 13.10.2022

British scientists have managed to obtain a broad-spectrum antibiotic from a potato bacterium. We are talking about a microorganism called Dickeya solani, first discovered 15 years ago. It is he who is responsible for the so-called wet rot on potatoes, which everyone has seen. This disease harms agriculture, but helped scientists from the University of Cambridge (UK) discover a new broad-spectrum antibiotic. Previously, microbiologists have already found that the bacterium D. solani has the ability to secrete an antibiotic, but another one is oocidin A. It has a high activity against many fungal infections in plants. It turned out that the bacterium can secrete another antibiotic - solanimicin. Scientists got it when they inhibited the genes responsible for the production of oocin A. Despite this inhibition, D. solani continued to retain antifungal activity. The researchers asked why this was so and learned about the bacterium's "backup" defense. In addition to isolating the antibiotic itself ... >>

Improved efficiency of flexible CIGS solar cell 13.10.2022

Researchers at the Swiss Federal Laboratory for Materials Science and Technology (EMPA) have achieved a world record efficiency of 22,2% for a flexible copper indium gallium selenium (CIGS) solar cell on polyimide plastic film. The German Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) confirmed the results. As of September 2021, the cell efficiency was 21,4%. The device was fabricated by low-temperature compatible evaporation to grow a light-absorbing CIGS semiconductor thin film. "The current improvement in efficiency is due to doping the light-absorbing semiconductor layer to improve its electronic properties," the research team said. The solar cell has been developed by a research group over the past 23 years. Their "record path" began in 1999 with an efficiency of 12,8%, which then increased to 14,1% (2005), 17,6% (2010), 18,7% (2011) and 20,4% (2013) and finally reached 20,8% (2019 ... >>

Speed ​​of the fastest network - 46 Mbps 12.10.2022

The fast internet network in the US just got faster. The ESnet network has been upgraded to ESnet6 and has now increased throughput to 46 terabits per second (Tbps). Now it works only for scientists. ESnet (Energy Sciences Network) is a high-speed computer network serving US Department of Energy scientists and their staff around the world. It is run by members of the Lawrence Berkeley National Laboratory. The very first version of ESnet was created in 1986 to connect scientists from various Department of Energy laboratories throughout the United States. The network allowed them to quickly exchange vast amounts of raw data. Over the past decades, ESnet has been updated many times to keep up with technological advances and to be able to send a huge amount of data obtained from scientific experiments. In 2021, the network transmitted 1,1 exabytes of data. ESnet6 consists of 24 km of dedicated fiber optic cables spanning ... >>

Automatic transcription of video conferences 12.10.2022

Google has offered users of the video conferencing service Meet the function of automatically transcribing video sessions. Initially, the service was positioned as a corporate one, and the new feature may be in demand by any users who would not like to miss something important. Until now, the ability to translate speech to text had to be implemented using various third-party services, but now it is an integral part of Meet. So far, the decryption works only in English, and in 2023 the developer promised to implement support for French, German, Spanish and Portuguese. Microsoft Teams, one of Meet's competitors, introduced call transcription last year, and it's somewhat surprising that it took Google so long to implement the feature. On the other hand, the function is now extremely simple - at the end of the video conference, the transcript of the communication session appears on the Google Docs platform. In the future, the company will ... >>

Rescuing teenagers from sleep deprivation 11.10.2022

At the beginning of the school year, teenagers can have a hard time getting used to the new schedule. As a result, they will experience a tired day, disrupted rest, mood swings, and trouble concentrating. Many teenagers, according to representatives of the National Sleep Foundation and the American Academy of Sleep Medicine, sleep less than eight hours. Although the recommended rate for them is eight to nine hours a day. But recently, scientists have discovered how to improve this situation. A teenager has two important factors. The first is the need to go to bed earlier through the school schedule, the second is the biological changes that occur with the body of a teenager. Rush Medical University experts tried to resolve this conflict with a single intervention. This experiment continued for two weeks. In order to help teenagers get rid of sleep deprivation, scientists used bright light therapy. Influenced the participants in this way twice in the morning on weekends. It just went on ... >>

The robot performed before the British House of Lords 11.10.2022

In its first address to the UK House of Lords, the realistically human-looking robot said artificial intelligence could be "both a threat and an opportunity" for artists. The Ai-Da robot got its name from mathematician Ada Lovelace. Back in the 19th century, the scientist made a description of an early version of the analytical engine (prototype of a computer) and compiled the world's first program for this machine. Ai-Da took part in a meeting of the House of Lords Communications and Digital Committee as part of a study on the future of the art, design, fashion and music industries. Officials were interested in how artificial intelligence could affect the creative industry in the future. "I create my images thanks to the cameras in my eyes. I can draw with my robotic hand thanks to the artificial intelligence algorithm. I create my own poetry by analyzing a lot of text, studying its structure and shape in order to create my poems. I differ from people in that I have no consciousness ... >>

Oil and gas flares are more dangerous than thought 10.10.2022

Experts from the USA studied the impact of oil and gas flares on the environment. The methane produced as a result of the operation of installations greatly harms the environment around the world. According to oil and gas companies, flares burn 98% of the natural gas emitted. But observations of three US oil and gas fields show that the efficiency is only about 91%. The natural gas leak is mostly methane. This greenhouse gas lingers in the atmosphere for only nine to 80 years, but its warming potential is 98 times that of carbon dioxide. So oil and gas companies are lighting flares by burning methane to produce less potent carbon dioxide and water. Industry and the US government assumed that these flares operated at XNUMX% efficiency. Previous research has shown that this may be overly optimistic. Genevieve Plante, an atmospheric scientist at the University of Michigan in Ann Arbor, and her colleagues sent ... >>

Plastic that can be endlessly recycled 10.10.2022

American scientists have developed a plastic that does not degrade when repeatedly recycled. This was reported by the press service of the University of Colorado in Boulder. Plastic waste poses a huge danger to the environment due to the fact that it practically does not decompose and serves as a source of microplastics that poison people and animals. Almost all types of plastics, including PET, are recyclable, but unlike metals, only a few times. In addition, the quality of the product decreases with each cycle. Zhang Wei came up with a plastic that practically does not degrade during recycling. The formation and decomposition of the polymers of which it is composed occur almost equally easily. The created polymer belongs to the class of polycyanurates, they have high strength, but are difficult to decompose. American chemists have found that this property of polycyanurates can be eliminated by replacing some of the carbon atoms with nitrogen and forcing the remaining carbon atoms with ... >>

Dogs smell human stress 09.10.2022

Dog owners often notice that during difficult periods, pets behave unusually. It turned out that this is not a game of imagination: dogs can really experience the negative experiences of others and react to them. Biologists from Queen's University in Belfast (Northern Ireland) found that dogs of different breeds can determine the stressful conditions of people with an accuracy of more than 90%. Thanks to the acute sense of smell, the four-legged "friends of man" experience the slightest deviations in the human biochemical trace. The bodies of many animals, including humans, constantly emit VOCs into the environment. This is a manifestation of an evolutionary mechanism: smells create a whole system of biochemical signals through which animals interact with each other. Because of a rather crude sense of smell, a person perceives only the strongest odors, but animals like dogs are able to capture even the weakest and most subtle aromas. Considering that humans have begun to domesticate some ten dog ... >>

Bionic pancreas 09.10.2022

A bionic pancreas with automatic insulin delivery technology has proven to be more effective at maintaining blood glucose levels in people with type 1 diabetes than standard insulin injections. This conclusion was made by US scientists. Automated insulin delivery systems, also called feedback control systems, monitor a person's blood glucose using a continuous glucose monitor and automatically deliver the hormone insulin when needed using an insulin pump. These systems replace fingerstick glucose measurement, continuous glucose monitoring with insulin delivery via multiple daily injections, or a non-automated pump. The 13-week trial, conducted at Nemours Children's Health and 15 other clinical centers in the US, included 326 participants aged 6 to 79 who had type 1 diabetes and used insulin for at least one year. Participants were randomly assigned ... >>

Greening cities will protect against global warming 08.10.2022

Scientists from Yale University have figured out how to reduce the negative effects of global warming. The more green spaces and street trees and rain gardens in cities, the more they manage to mitigate the effects of the climate crisis and global warming. Scientists from China and the United States came to this conclusion after analyzing satellite data from 2000 cities. They also found significant differences in temperature between cities and rural areas nearby, which was associated with heating systems. The analysis period was from 2002 to 2021. The study found that cities warmed by an average of 0,56°C per decade during the day and 0,43°C at night. By comparison, rural areas warm on average 0,4°C per decade during the day and 0,37°C per decade at night. This means that urban areas are warming 29% faster than rural areas. In order to level this difference, cities need to be more actively greened. Tree planting, in which exposed concrete and asphalt surfaces are replaced ... >>

Pills instead of sports 08.10.2022

Experts say that there are diseases in which any serious physical activity is simply contraindicated. Physical activity is an important part of everyone's life because it promotes health and relieves stress. But not everyone has the opportunity to play sports, for example, it is problematic for the elderly or those who have medical contraindications. Scientists have come up with a way that will allow them to solve such a problem. Experts have created a pill that can replace sports. In one 2017 study, they proved in mice that fitness can be improved with GW501516 and GW1516. It is sold illegally on the black market to improve performance. After taking the drug for 8 weeks, mice could run on a treadmill for 70% longer than the control group - more than 100 minutes. Later, the Tokyo Medical and Dental University held a similar ... >>

Cricket and carrot food print 07.10.2022

3D printing will help consumers overcome immediately in the consumption of insects. This conclusion was made by researchers at the University of Singapore Technology and Design (SUTD). An aging population will increase the demand for protein-rich foods. Insects and algae can become a powerful source of protein. The production of these products has less impact on the climate and does not require as many additional resources, the researchers say. But feeding the planet with insects is not an easy task. Naturally, people get disgusted as soon as they see a beetle on their plates, or even mentally imagine such food. "The look and taste of these alternative proteins is confusing to many," says SUTD professor Chua Chi Kai. Professor Chua is the co-author of a new study "Systems engineering approach to optimize multi-component alternative food inks for protein-enriched 3D printing. He believes that 3D printing may prove to be a viable solution to help increase the attractiveness of ... >>

Banana skin flour 07.10.2022

American researchers made flour from a banana skin and added it to the dough. The biscuits they made turned out to be healthier than biscuits made from wheat flour. To make flour from banana skins, the researchers dried and ground the skins of ripe bananas into a fine powder. By mixing flour with butter, milk powder, powdered sugar, vegetable oil and wheat flour, they baked a batch of cookies. Scientists have found fiber, magnesium, potassium, antioxidants and other important nutrients in banana peel flour. In addition, biscuits made with banana peel flour were healthier, lower in fat and protein, higher in phenols, and better in antioxidant activity than regular biscuits. ... >>

Mandatory disposal of satellites 06.10.2022

The US Federal Communications Commission (FCC) has approved new rules that require companies launching satellites into low Earth orbit to dispose of them within five years of completing missions. Under the old rules, companies had to dispose of satellites within 25 years of the completion of a mission. Thus, the regulator intends to minimize the negative consequences of space debris in orbit. FCC chief Jessica Rosenworcel said 25 years is too long. “There is no longer any reason to wait so long, especially in low Earth orbit. The second space age has arrived. To continue to develop, we need to do more cleaning up after ourselves,” she stressed. Rosenworsel noted that about 1957 satellites weighing a thousand tons have been launched since 10, and more than half of them are no longer in use. According to her, the new rule of "five years" will "mean more responsibility and less ... >>

Green hydrogen scooter 06.10.2022

The French company Mob-Ion has invented a model of a green hydrogen scooter. To refuel such a scooter, you only need to replace the discharged cartridge with a charged one. The volume of hydrogen in each cartridge is enough for 15 kilometers. In total, the scooter can contain 3-4 of these hydrogen cartridges, which will allow you to drive up to 60 kilometers on it without recharging. Today, EU countries are actively developing technologies that allow transport to increasingly use green hydrogen instead of environmentally polluting fossil fuels. At the end of last year, for example, French designers developed an autonomous hydrogen engine for aircraft. ... >>

rubber computer 05.10.2022

A soft computer made of rubber blocks veined with a silver-rubber compound can perform simple calculations after being compressed. Ryan Garn of Pennsylvania State University and a colleague developed a cube-shaped soft computer that responds to compression. The new computers were built by combining rows of rubber blocks through which veins of a silver-rubber compound run. The different block configurations act as different circuits that, when combined and connected to electricity, allow the device to perform mathematical calculations. “Although it is unlikely that these computer models will be able to replace traditional devices or be faster in computing, Garn’s team expects the new technology to be used in robotics, where soft works can make decisions based on what they touch in their environment. ", the article says. To advance the new technology, Garn and his colleagues are working on a tone ... >>

Kombucha nanofiber to replace leather and plastic 05.10.2022

Texas-based Bucha Bio has raised $1,1 million to make bacterial nanocellulose from kombucha kombucha. The newest material can be used instead of leather and plastic. The first (already this year) the world will see Hikari. It has a translucent aesthetic and unique processing options to allow it to function as an alternative to animal skin, synthetic leather, or other types of synthetic materials. "Next-generation biomaterials are a game-changer in the marketplace. The way they are produced is absolutely in line with my personal vision for a more sustainable future," said Eric Rubenstein, founding managing partner of New Climate Ventures and one of the startup's investors. The demand for sustainable materials in all industries is now growing unspeakably. More than $2015 billion has been invested in the biomaterials sector since 2,3, according to the Material Innovation Initiative. ... >>

Efficient installation for energy storage in compressed air 04.10.2022

Compressed air energy storage systems are nothing new. The problem was their relatively low energy efficiency, which Chinese scientists successfully solved. Based on the development in Hebei Province, the world's most advanced 100 MW air-compression energy storage system has been created, tested and will be put into commercial operation by the end of the year. The world's first CAES (compressed air energy storage system) project on a utility scale was implemented in Germany in 1978. The plant is still in operation today, providing an output power of 290 MW. CAES equipment pumps atmospheric air into voids in the ground, compressing the air to a pressure of about 140 atmospheres. The efficiency of the German installation is 40%, which is significantly lower than pumped storage power plants with energy reserves in the process of pumping water masses to a great height (efficiency up to 75%) and battery storage, the efficiency of which reaches 90%, but is realized in the course of the most serious financial injections. In pr ... >>

Robot tablet 04.10.2022

A range of antibiotics, insulin, and a variety of other drugs must be given by injection. This is difficult and rather painful, but the milder oral route - for example, in the form of tablets - does not always allow the drug to be delivered to the blood. Once in the gastrointestinal tract, the drug meets with a number of tests, which not everyone is able to overcome. The thick intestinal mucosa acts as a sticky trap, trapping particles and preventing them from penetrating further into the tissues. Shriya Srinivasan and her colleagues at the Massachusetts Institute of Technology (MIT) took on this challenge. Scientists have developed a miniature robotic device RoboCap. No larger than conventional medicinal capsules, at one end it carries a reservoir (about 342 millimeters cubic) where the desired drug is placed, and at the other - a propulsion system that allows the robot to actively deliver the drug to the target, protecting it from stomach acid and overcoming mucus ... >>

Lonely and unhappy people age faster than smokers 03.10.2022

According to a new study by Deep Longevity, mental health affects the rate of aging more than smoking and certain diseases. Especially vulnerable to premature aging were lonely and unhappy people who do not sleep well. With age, various molecular damage accumulates in our cells, contributing to the overall aging of the body and the development of various diseases. In some people, these molecular processes are more intense than in others. This condition is commonly referred to as accelerated aging. Fortunately, the increase in the rate of aging can be detected even before the first consequences appear. Deep Longevity is developing models that predict the rate of aging based on epigenetic changes, end-of-chromosome changes (telomeres), gene expression, and concentrations of various metabolites. These models can be used to develop anti-aging therapies. However, now a team of American and Chinese ... >>

A new data rate record in a coherent optical network 03.10.2022

Nokia Bell Labs has demonstrated the ability to transmit optical signals over 100 km over standard single-mode fiber (SSMF) at a record high speed of 260 Gbaud (2,08 Tbps). During a demonstration at the European Optical Communications Conference (ECOC) 2022 in Basel, Switzerland, a provisional speed record of 220 Gbaud was broken. This result marks the first milestone for scaling long distance data transmission systems at rates greater than 2 Tbps per wavelength. The issue of improving the energy efficiency of transponders is a constant challenge for the industry," said Haik Mardoyan, senior researcher at Nokia Bell Labs. The specialist has collaborated with Keysight Technologies to develop dual polarization quadrature phase-shift keying (DP-QPSK) coherent transmission technology over 100 km single-mode fiber. New Keysight's M8199B Arbitrary Waveform Generator (AWG) provides bandwidth ... >>

Clothes splattered from the spray 02.10.2022

Scientists have learned how to create clothes from a spray. It is simply sawn through the body and turned into clothes. The demonstration took place at Paris Fashion Week. At the end of Coperni's Spring/Summer 2023 show, a team of scientists applied a special liquid to the model's body, which eventually turned into a white dress with a slit from the thigh. The composition of the liquid includes cotton fibers in polymer impregnation, which, upon contact with the skin, turn into a fabric. The innovative technology of cotton fibers was invented by the Spanish designer Manel Torres. With the help of a spray gun, cotton fibers are sprayed over the human body. Clothing can be given almost any shape. After the mixture hardens, all the applied cotton fibers turn into real elastic clothing. The created item of clothing does not stick and can be easily removed and put on. Moreover, it can be turned into a spray again and dispersed again if you want to reshape your clothes. ... >>

Soil batteries for storing solar energy underground 02.10.2022

British scientists have proposed an interesting concept for storing solar energy underground. The idea is to create batteries for storing and transmitting "green" energy based on microbes living in the soil, namely: to stimulate certain microorganisms in the soil, using recessed electrodes to generate electricity from solar panels. According to Dr. Michael Harbottle from Cardiff University, the project could be massive. The scientist believes that it is simply necessary to use a rich natural resource, the soil, to solve the problem of renewable energy storage. The process of transferring energy in soil is somewhat similar to photosynthesis, when plants take in CO2 and turn it into oxygen. Some photosynthesis processes take place underground. Underground living organisms, according to the researcher, will be able to use the energy received to reduce carbon dioxide and create a more complex chemical - acetate. Harbottle says that acetate can keep ... >>

Iron mining on Mars 01.10.2022

Australian researchers at Swinburne University of Technology have developed a process to produce iron on Mars. They propose using concentrated sunlight as an energy source, and extracting iron from regolith using carbothermal reduction. Experiments on the Perseverance rover have shown the possibility of extracting oxygen on the Red Planet using the electrolysis of carbon dioxide (CO2). During this process, a large amount of carbon monoxide (CO) is released as a by-product. The researchers propose to combine an oxygen plant with iron production to use by-products. In their calculations, the scientists showed that the hot gas produced by the electrolysis of carbon dioxide would be rich in CO (91%). It can be used to preheat regolith. In addition, by condensing the monoxide, pure carbon can be obtained. The researchers analyzed the composition of the Martian re ... >>

Walking in nature is good for the brain 01.10.2022

Cities represent a radical new kind of environment that, despite its many benefits, often aggravates a person's mental health. Research has linked urban environments to an increased risk of anxiety, depression, and other mental health problems, including schizophrenia. The solution to this problem has long been known: visiting the wild. Even short walks in the wild are associated with a range of mental and physical health benefits, including lower blood pressure, reduced anxiety and depression, improved mood, better concentration, better sleep, better memory, and faster injury recovery. Numerous scientific studies point to this correlation, but scientists still cannot exactly explain what processes in the body affect the fact that people feel better in nature. A good place to look for clues is the amygdala, a small structure in the center of the brain that is involved in stress processing, uh ... >>

Microscope for examining the brain without opening the skull 30.09.2022

Korean scientists have invented a very unusual microscope. With it, you can create high-resolution 80D images of a neural network without trepanation. A new type of holographic microscope has been developed by a research team led by Choi Wonshik, deputy director of the Center for Molecular Spectroscopy and Dynamics of the Institute of Basic Sciences, Professor Kim Moonseok from the Catholic University of Korea and Professor Choi Myunghwan from Seoul National University. The novelty is based on holographic technology. Researchers have developed a way to better select singly scattered waves, using the fact that they have similar reflection shapes even when light hits from different angles. At the same time, in their project, the specialists used a rather complicated algorithm, as well as a numerical operation that analyzes distortion and interference between different waves of light. As a result, they got a microscope that fixes more than XNUMX times more light energy on not ... >>

Charger for electric car 1 km per second 30.09.2022

Geely has introduced a 600 kilowatt charger. It is ready for mass production, but only one electric car can charge at that speed. According to preliminary calculations, such a charge will be able to replenish about 300 km of charge in 5 minutes. Currently, this "supercharger" outperforms most modern chargers by two or even three times. True, only one electric car manufactured by the Geely sub-brand Zeekr can be charged with such charging. The electric car called 001 has a Qilin battery from Contemporary Amperex Technology Co. Limited. Previously, these batteries will be put into mass production in 2023. ... >>

Curcumin Prevents Vision Loss 29.09.2022

Researchers at Imperial and University College London have developed a new way to deliver curcumin that scientists believe will help diagnose and treat glaucoma more effectively at an early stage. Glaucoma is a group of eye diseases characterized by increased intraocular pressure. The patient may develop various visual defects up to blindness. The pigment contained in turmeric protects the nerve cells of the retina from damage. Previously, researchers believed that curcumin could only be delivered orally, but this method could not be effective because the component is poorly soluble in the blood. In order to get the right dose of the substance, a person would have to take up to 24 tablets per day, which is fraught with digestive problems. Scientists have solved this problem by developing a special "nanocarrier" in which curcumin is contained inside a surfactant that is safe for health and is used in eye drops. Specialists ... >>

It will be impossible to control superintelligent AI 29.09.2022

The idea of ​​overthrowing humanity with artificial intelligence has been discussed for decades, and in 2021 scientists delivered their verdict on whether high-level computer superintelligence can be controlled. The catch is that in order to control a superintelligence that is far beyond human understanding, it will be necessary to simulate this superintelligence, which can be analyzed and controlled. But if people are not able to understand this, then it is impossible to create such a simulation. Rules like "don't hurt people" can't be set if people don't understand what scenarios AI has to offer. Once a computer system is running at a level beyond the capabilities of our programmers, then no more limits can be set. The superintelligence presents a fundamentally different problem than those usually studied under the slogan of "robot ethics". This is due to the fact that the superintelligence is multifaceted and, therefore, has the potential to ... >>

Yeast transplanted with human genes 28.09.2022

Dutch biotechnologists transplanted human genes responsible for muscle metabolism into yeast. In this way, it will be possible to study cellular processes, the understanding of which will help in the search for a cure for cancer. Yeast DNA has been modified before, but this is the first time scientists have been able to include such a large and important piece of the human genome. Humanized yeast is easier to grow than human cells and tissues. It is also easier to study them - the model turns out to be clean, there are no extraneous interactions in it. Using genetically engineered yeast, researchers will study the process of breaking down sugar to capture energy and create cell blocks inside muscle cells. "This seems strange because yeast are simple single-celled organisms and humans are very complex systems, but the cells in both cases act very similarly," said lead author Pascal Daran-Lapouhade. ... >>

Cooling without electricity 28.09.2022

It often happens that in those countries in need of advanced cooling systems, there is no infrastructure to power such installations. A new development by scientists at MIT can solve this problem. The thing is that they have created a system that combines evaporative cooling, radiative cooling and thermal insulation. The new development is capable of cooling down to 10,5 C compared to ambient temperature. Because the system is in the form of a three-layer panel, it can be safely placed over or around the item to be cooled. The researchers cite the fact that it does not require electricity and that some of the materials used in the system are "easily available and relatively inexpensive" as a plus for their development. ... >>

Created antimalarial mosquitoes 27.09.2022

About half of the world's population lives in areas where malarial mosquitoes are found, and every year millions of people get sick and thousands die from malaria. To create yet another way to fight this devastating disease, an international team of scientists has tampered with the genes of the malaria mosquito so that it becomes the malaria killer itself. Malaria mosquitoes and the parasites they carry are becoming resistant to insecticides and drugs. The disease is transmitted from person to person through mosquito bites: the causative agent of the disease, the malarial Plasmodium, must develop in the intestines of the mosquito and penetrate into its salivary glands in order for the insect to become dangerous to humans. However, only one in ten mosquitoes will live long enough for Plasmodium to reach its salivary glands - and in their new work, the team of researchers tried to further reduce their number. By editing the genome of the malaria mosquito Anopheles gambiae (this species predominantly carries malaria in Africa) ... >>

Brewing coffee with a laser 27.09.2022

German scientists came up with a laser for making coffee. The device not only prepares a drink 300 times faster, but also reveals its taste and aroma properties better. One of the popular ways of brewing coffee - cold-brew - involves cold extraction of the drink. Ground coffee beans are poured with water and left to infuse. It takes about 24 hours to brew a cold drink, but modern equipment reduces the time to 12 hours. There is a way to speed up the process. The method is based on laser synthesis and processing of colloids (LSPC). It is usually used to create solutions of suspended nanoparticles. The researchers took a neodymium-doped yttrium-aluminum garnet (Nd:YAG) laser tuned to 532 nanometers and created 125 picojoule pulses lasting just 10 picoseconds. After that, the laser passed through the coffee solution. They passed it through a solution of ground coffee mixed with water for about 8 ... >>

A new method for searching for axions is proposed 26.09.2022

An international group of physicists has proposed a new laboratory method for detecting particle interactions. The search for axions, a hypothetical form of dark matter, has reached a new level, writes Alternative Science. Physicists tested a new spin amplifier, by indirect indicators of which they determined the mass of the axion within the allowable "axion window" - from 0,01 to 1 meV. This bridged the gap between previous laboratory searches and astrophysical observations. The new method for finding axions uses the following prediction about their behavior: when fermions (particles with half-integer spin) exchange axions, they should produce an exotic dipole-dipole interaction that could in principle be detected in the laboratory. In the latest study, a team led by Xinhua Peng from the University of Science and Technology of China, together with the team of Dmitry Budker from the Helmholtz Institute, combined a large ensemble of polarized rubidium-87 (87Rb) atoms (a source of electrical ... >>

Growing meat from mushrooms 25.09.2022

Singapore scientists have used button mushrooms to create an alternative meat. The researchers grew mushrooms on food waste, which allowed them to saturate them with important ingredients and make them more nutritious. I must say that earlier legumes, wheat gluten, soy and even brewer's yeast were used for vegetable analogues of meat. Scientists assure that their new meat will taste almost the same as the usual one. This is due to the higher content of amino acids, as well as aspartic and glutamic acids. The latter are usually found in animals and give the meat the necessary flavor. Another new method will allow the reuse of common food waste from agricultural production - wheat stalks, brewer's grains or soybean husks. These wastes, according to experts, are emitted annually 39 and 14 million tons, respectively. The lead author of the project, William Chen, believes that the use of these products for growing mushrooms allows us to offer a healthier alternative to meat. Official ... >>

Living synthetic cells created 24.09.2022

Researchers at the University of Bristol in the UK have taken a big step forward in the field of synthetic biology. Scientists have developed a system that performs several key functions of a living cell, including energy generation and gene expression. Scientists have previously focused on getting artificial cells to perform a single function, such as gene expression, enzyme catalysis, or ribozyme activity. If scientists unlock the secret to individually creating and programming artificial cells that can more closely mimic life, it could open up a myriad of possibilities in everything from manufacturing to medicine. While some engineers are focusing on redesigning the cells themselves, others are looking for ways to cut existing cells down to fragments that can then be redesigned into something relatively new. To accomplish this latest bottom-up bioengineering feat, the researchers used two bacterial colonies - Escherich ... >>

MSI SPATIUM M570 PCIe 5.0 SSD 24.09.2022

MSI has unveiled its new SPATIUM M570 SSD. The main feature of the device is simply incredible data transfer speed thanks to the latest PCIe 5.0 interface. Due to this, the manufacturer was able to demonstrate more than 12 MB / s when reading and more than 000 MB / s when writing data. This is about twenty times faster than SATA10 SSDs, so the difference in system performance will be quite noticeable. Previously, drives running on the PCIe 000 interface provided a maximum speed of 3 MB / s, which is also quite a decent indicator compared to 4.0-7 MB / s for SATA000 drives. But with the gradual transition to PCIe 500, the situation should have changed dramatically - and that is exactly what happened. 600 GB/s when writing data is an incredible performance for a mass-produced SSD, while the manufacturer also provides the SPATIUM M3 model in fairly decent amounts of memory.

Found the closest black hole to us 23.09.2022

An international team of scientists studied 168065 stars and found that one of them orbits a black hole. Now it is the closest black hole to the solar system. In addition, the researchers suggest that there are other dormant black holes lurking nearby that we have not yet discovered. An international team of astrophysicists in search of black holes studied the trajectory of the stars in the Milky Way. Using data from the European Space Agency's Gaia Observatory, scientists studied all 168 stars they thought had companions. The star Gaia DR065 3 (abbreviated as Gaia BH4373465352415301632) especially attracted their attention. After studying its movement, scientists found that the star revolves around a small black hole, the mass of which is 1 times the mass of the Sun (almost the minimum possible mass of a black hole). To confirm the find, scientists analyzed the motion of Gaia BH10 using other telescopes, studying how the gravity of other bodies affects the star. ... >>

Virtual reality as soothing during surgery 23.09.2022

American doctors from the Beth Israel Diaconis Medical Center performed a surgical intervention in which virtual reality was used, which allowed the use of less sedative drugs. During the study, surgeons performed an operation to treat carpal tunnel syndrome. Usually during the procedure, patients are given the drug propofol, as well as local anesthesia. As a result, patients are under a strong sedative effect of the drug, which makes them sleepy and calm. However, this method can lead to a drop in blood pressure and narrowing of the upper airways, which increases the risk of stroke, heart attack, or respiratory failure. For the experiment, the researchers divided 34 subjects into two groups: the first was immersed in virtual reality and used traditional drugs, and the second was given only propofol. In VR glasses, participants could independently choose their surroundings: meadow, forest or mountains. As a result, patients from the first group, on average, need ... >>

REM sleep warms up the brain and saves from hypothermia 22.09.2022

Researchers at the University of California, Los Angeles have published a paper in The Lancet providing a new explanation for the role of REM sleep in warm-blooded creatures. The authors of the work believe that it was formed in order to warm up the body and maintain its performance in case of danger. Scientists have noticed that in nature, warm-blooded creatures with lower body temperatures tend to have longer periods of REM sleep. And in humans and other animals with a higher body temperature, the duration of this phase is usually shorter. Researchers believe that this ratio is not accidental. During the REM phase, the brain becomes very active, resulting in an increased heart rate and fever. Since REM sleep comes after slow sleep, in which all processes slow down, it is needed to avoid hypothermia, scientists say. REM sleep can be thought of as a thermostatically controlled brain heating mechanism triggered by falling ... >>

Created diffraction gratings for the world's most powerful laser 20.09.2022

Livermore National Laboratory researchers Lawrence (LLNL) and colleagues have designed and built new diffraction gratings for compressing high-energy laser pulses in the world's most powerful laser system. The new design will make it possible to transmit 10 PW of energy (1016 W) in one pulse. This is about ten times the total capacity of the US power grid, which is necessary for many areas of science. Four HELD diffraction gratings (high energy low dispersion gratings) with dimensions of 85? 70 cm each will be installed in the ELI-Beamlines L4-ATON laser system in the Czech Republic. Such meter-sized HELD gratings could potentially contribute to the creation of future ultrafast laser systems with a power of 20 to 50 PW. In a laser system, diffraction gratings are used to expand and then compress broadband laser pulses. The method of amplifying chirped pulses (eng. Chirped pulse amplification, CPA) in 1985 before ... >>

Tourism helps treat dementia 20.09.2022

Scientists from China and Australia have found that tourism helps fight dementia. Their findings are published in the journal Tourism Management. The researchers argue that travel can be used as a way to combat age-related amazement along with medication. Trips allow you to get new emotional experience (hedonic tourism, conscious tourism), cognitive experience (acquaintance with new information, comparison of past and current travels), creative experience (family tourism, group tours) and sensory experience (contemplation of landscapes, leisure on the beach). All these factors contribute to the improvement of dementia, the scientists report. ... >>

Microplastics found in plant leaves 19.09.2022

In the studied samples of plant leaves, scientists for the first time found traces of microplastics. The discovery was made at the University of Presov in Slovakia. Plants of the genus Dipsacus have characteristic paired leaves. They form a kind of receptacles that collect water and attract insects to it. Fragments and fibers of multi-colored microplastics up to 2,4 mm long were found there. No extraneous sources of pollution around the area were recorded, so the plastic got into the flowers from the polluted atmosphere, the scientists concluded. The appearance of plastic in plants is an indicator of possible current and environmental pollution by microplastics. However, as noted, further research is needed to obtain accurate information and test the methodology for a possible assessment of the local load of microplastics on the environment. ... >>

Plastic film that kills viruses 18.09.2022

A team of scientists from Queen's University Belfast has developed a plastic film that can destroy viruses that fall on its surface under room lighting. The created film has a self-sterilizing effect, which is achieved due to a thin layer of particles that absorb ultraviolet light and produce reactive oxygen species. They help to kill viruses, including SARS-CoV-2. During the experiments, experts tested it on two strains of the influenza A virus, picornavirus EMCV and coronavirus. The film showed effectiveness not only when exposed to UV lighting, but also under normal room light with a fluorescent lamp. In addition, unlike existing disposable plastic films, it is much more environmentally friendly. The authors propose to use the development in medical institutions, public places and food production. ... >>

Solved the main problem of growing plants in space 18.09.2022

The main obstacle to space farming is the lack of sufficient sunlight. But scientists have found a solution to this problem - the good old electricity and chemistry will help the farmers of the future. In the absence of the required amount of sunlight, the process of photosynthesis is impossible. And with it, the absorption of carbon dioxide, which is part of the air. Until recently, this has called into question crop production on the Moon or on Mars. But now scientists have developed a new method of growing plants in the absence of natural light. It consists of the use of electricity and chemical fertilizer to power the process of photosynthesis. Feng Jiao, an electrochemist at the University of Delaware, USA, conducted a series of tests with mushrooms, algae, yeast and lettuce. At first, the test plants did not grow in conditions of complete absence of sunlight, but the scientist decided to feed them with acetates and everything was successful. The researcher found that plants can absorb acetate, turning it into ... >>

Found the oldest artificial cosmetics 17.09.2022

In China, archaeologists from the Chinese Academy of Sciences and the Shaanxi Academy of Archaeology have uncovered the remains of the world's earliest known cosmetics while excavating in the northwest province of Shaanxi.

More solar panels in Tokyo 16.09.2022

The Tokyo Metropolitan Region Government has announced a new policy that mandates the installation of solar panels on some of its new homes as part of a move to promote the use of solar energy. The initiative is scheduled to start in 2025 and will be the first of its kind in Japan, according to The Japan News. About 50 developers building buildings with a total area of ​​at least 20 m2 per year will fall under the new rules requiring the installation of solar panels. However, the proportion of solar panels required for installation will differ from area to area, taking into account the degree of insolation in a particular place. For example, if in the districts of Chioda and Chuo, where many tall buildings are located, 30% of the roofs should be covered with panels, then in low-rise areas - up to 85%. Since the life cycle of panels is about 20-30 years, the county government will also set up a system to promote their recycling with an eye to prepare for the mass replacement of panels in the future. ... >>

Production of hydrogen fuel from air 12.09.2022

Hydrogen has huge potential as a clean fuel: it is plentiful (mainly in compounds like water), produces no harmful emissions, and can be used to store energy from solar, wind and tidal sources. However, there are problems with producing enough material in a practical and affordable way. Separating hydrogen from water can require complex technology, as well as clean fresh water, which is not available everywhere in abundance. An international team of scientists has developed a new prototype device that can harvest water from moist air before splitting it into hydrogen and oxygen. What's more, it can work in places where humidity - the concentration of water vapor in the air - is as low as 4%. The device assembled by the researchers is a prototype electrolyzer powered by electricity from renewable energy sources to decompose water into its elements, hydrogen and oxygen. ... >>

A new kind of space balloon for space travel 12.09.2022

Space Perspective is one of the few companies looking to cut space tourism costs. Space Perspective will charge $125 for a ticket to fly to the edge of space aboard its zero-emission space balloon. The company has unveiled the final design for its "Neptune" balloon spacecraft, a pressurized capsule that will take passengers to the edge of space, although they won't technically reach space.

A new record for the duration of thermonuclear fusion 12.09.2022

An international group of researchers managed to keep thermonuclear fusion at a temperature of 100 million kelvins for 20 s. This is a new record. Previously, scientists have been able to either reach such a high temperature, or keep the plasma for a long time. For several decades, scientists have been trying to create stable thermonuclear reactions for electricity. Although these studies have made some progress, the main goal of creating a sustainable process still remains far off. The smallest deviations lead to instability that prevents the reaction from proceeding, the scientists explain. The biggest problem is related to the release of heat, which is measured in millions of degrees. No materials can hold such a hot plasma, so it levitates in a magnetic field. Two approaches are used to control plasma: edge and internal transport barrier. In the first case, the external magnetic field prevents the plasma from escaping, and in the second case, the high-pressure region in the center ... >>

Atomic clock entanglement experiment 11.09.2022

Physicists for the first time "confused" two optical atomic clocks. This breakthrough could be a way to go beyond even the most advanced current timekeeping limitations, as well as being a fantastic tool in the exciting field of quantum computing: quantum cryptography. Atomic clocks are used as timers, measuring the resonant frequencies of atoms as their electrons switch between energy levels. Traditionally this has been done using cesium atoms and microwaves, but since 2000 new atoms have been used using visible light. This is an optical atomic clock that uses elements such as ytterbium, mercury and strontium. Optical atomic clocks have recently been used to make impressive strides in accurate timekeeping. They are 100 times more accurate than traditional cesium atomic clocks. So precise that they could soon be used to redefine the second . But they also have their limitations. Especially when several ... >>

Created a unique cold matter 10.09.2022

A team of scientists at Kyoto University has created the coldest matter in the universe. It is three billion times colder than interstellar space. For the experiment, scientists used fermions, which physicists call any particles in the composition of matter. They cooled the ytterbium atoms to about a billionth of a degree above absolute zero, the hypothetical temperature at which atomic motion would cease. Lasers were used for cooling. The conducted experiment simulates the model of quantum physics, first proposed in 1963 by theoretical physicist John Hubbard. It allows atoms to exhibit such unusual quantum properties as superconductivity. It is noted that interstellar space is never so cold, as it is evenly filled with cosmic microwave background radiation. According to scientists, the created matter is even colder than the Boomerang Nebula, which is the coldest known region of space. The temperature is only one degree above absolute zero. ... >>

Hearing aid that reads lips even through a mask 09.09.2022

Engineers from the University of Glasgow have created a hearing aid that lip-reads words even through a mask on the interlocutor's face. The device uses artificial intelligence - the radar scans the movements of the lips and determines what sound they are typical for. For open faces, the accuracy is 95%, for closed faces, 83%. The new hearing aid will also use traditional sound amplification technology. The scanner will help people hear well both in normal conditions and in noisy environments. Prior to this, the effect of a cocktail party for the hearing impaired was provided by devices that read lips with the help of a camera. But the video recording of the interlocutors could violate their privacy. "Approximately 5% of people in the world have a hearing impairment - that's 430 million people. Hearing aids have changed the lives of many of them," said Kammer Abbasi, co-author of the development. ... >>

Powder coating of electrodes will improve battery parameters 09.09.2022

In recent years, scientists have been actively developing new types of rechargeable batteries, the performance of which should in all respects exceed that of lithium-ion batteries. Lithium metal batteries are considered one of the most promising types, but they have one drawback - the rapid growth of dendrites, tree-like conductive metal formations, which first reduce the battery capacity and then lead to its complete failure. Researchers at Rice University have found a promising solution to the problem of dendritic growth. To prevent this, a coating of a special powder is applied to the surface of the electrodes, which allows you to keep the battery in good condition for a long time. In lithium metal batteries, the graphite electrode used as an anode in lithium ion batteries has been replaced with a pure lithium metal electrode. This allows for a significant increase in energy storage density, a reduction in charging time, and an order of magnitude higher ... >>

Artificial intelligence plays football 08.09.2022

Google's DeepMind artificial intelligence division taught SHI humanoids how to work as a team, after which they played football. The researchers trained simulated AI to play two-on-two football as part of an experiment that aimed to improve coordination between AI systems and discover new ways to create human-like “general-purpose artificial intelligence.” "Our agents have acquired skills including agile movement, passing, and work sharing, as demonstrated by a range of statistics," the DeepMind researchers wrote in a blog post. "Players demonstrate both high-frequency motor control and long-term decision making, including predicting the behavior of teammates, resulting in coordinated team play." The players learned how to fight for the ball, perform through passes to a teammate, and also make tricks. In separate simulations, humanoids were taught to perform with ... >>

Crab and Shrimp Batteries 07.09.2022

Scientists from the American universities of Houston and Maryland have found a way to create batteries from recycled crab shells. Now the most common type of batteries are lithium - they have a high energy storage density in a fairly compact size, but are very expensive to manufacture and can catch fire. In addition, they cause significant damage to the environment, for example, polypropylene and polycarbonate separators that are part of such batteries decompose for hundreds or thousands of years. The team led by Liangbing Hu saw the promise in zinc batteries - this material is much more abundant in the earth's crust, and its extraction is cheaper. Scientists have already managed to create prototypes with high power density, and the technology turned out to be no more expensive than lead-acid batteries. The main disadvantage of such batteries is a rather short service life, but scientists managed to solve this problem by making the device rechargeable and more reliable using natural ... >>

Smartphone use improves memory 07.09.2022

Scientists from University College London (UK) believe that the use of gadgets allows you to remember even unsaved information on them Previously, neuroscientists expressed concern that excessive use of gadgets could damage brain function. However, scientists deny this. British experts conducted a study involving 158 volunteers aged 18 to 71 years. They were shown up to 12 numbered circles on the screen of smartphones: some of them had to be moved to the left, and others to the right. The movement of the circle to one side was estimated at ten times more than to the other. Participants completed the task 16 times. As it turned out, they used digital devices to store parts of expensive chains. This, according to scientists, improved their memory by 18%. Completing the task with moving low-value circles also improved memory by 27%, even in people who never set any reminders for it. As it turned out, the volunteers remember ... >>

Assembling furniture without tools 06.09.2022

A graduate student at the Hebrew University of Jerusalem presented his work at a meeting of the American Chemical Society. He suggests using a 3D printer and high-tech ink, which, when applied to certain areas of the workpiece, will deform it, giving it the desired shape. Kam's concept is based on the tendency of wood to warp under the influence of heat, pH and humidity changes. According to him, the furniture of the future can be produced without wood processing tools and complex assembly. "This idea challenges the way we've approached design for centuries," Kam says. - Until recently, the goal was to create structures that will not change over time. What we got as a result is a little different ... it's about making sensitive structures that change the concept of engineering. "Developing adaptive materials is not a new idea. In parallel with the Israeli scientist, Tiffany Cheng from the University of Stuttgart is working on it. Cheng plan ... >>

Rapid pulse speeds up time 06.09.2022

When the activity of the sympathetic nervous system increases, that is, the heartbeat accelerates, people feel that time flies faster. These conclusions were made by scientists from the University of Liverpool. During the experiment, volunteers wore heart rate sensors and changes in the electrical conductivity of the skin - it is affected by the activity of the sweat glands. People went about their normal business and each hour wrote down how fast or slow they thought the last 60 minutes had gone. It turned out that when the sympathetic nervous system was more active, it seemed to the volunteers that time was running 10% faster. It's relatively small. "Studies in general show that boredom, social isolation and stress are associated with a slowdown in the passage of time, and social satisfaction and low stress levels are associated with a faster one," the scientists said. ... >>

A man's character does not depend on his brothers and sisters 05.09.2022

A sister will not make a younger brother more feminine, and a brother will not affect the masculinity of a sister. This conclusion was made by scientists from the United States. The authors of the study focused on the relationship between children and their closest older or younger siblings. A unique data set was collected, combining 12 large representative surveys from 9 countries. It covered 85 thousand people. The study also assessed more personality traits than previous studies on the topic. Finally, an index was created that describes the degree of possession of a characteristically female character. This made it possible to comprehensively check whether growing up with a sister leads to the formation of more or less gendered personality stereotypes in brothers. It has been established that the gender of a brother or sister does not affect the personality of the child. For all 9 personality traits and the total index, it has been proven that people with older sisters generally demonstrate the same character traits as people with older brothers. No differences in character were found between l ... >>

Application for communication under water 04.09.2022

The University of Washington has developed the first underwater messenger AquaApp. The application works with the help of acoustic signals, which, compared to Bluetooth or Wi-Fi, transmit information more efficiently underwater. To do this, you need a smartphone or smart watch, as well as a waterproof case designed for immersion depth. The AquaApp interface allows users to select from a list of 240 preset messages that respond to hand signals commonly used by professional divers. The authors of the project noted that the quality of gestural communication under water is strongly affected by poor visibility at depth. This problem, according to them, can be solved by communication using smartphones. ... >>

Muscle strength affects brain health 04.09.2022

Canadian scientists have found a link between low muscle mass and cognitive decline. The experts analyzed the results of the Canadian Longitudinal Study of Aging (CLSA), conducted over a period of three years, and revealed how muscle mass affects the development of cognitive functions. The researchers were interested in whether muscle weakness was associated with a risk of dementia. To do this, they studied questionnaires from 8 participants aged 279 and over on how low muscle mass affects further cognitive decline in three areas - memory, executive function and psychomotor speed. "We found that a decrease in muscle mass over three years was accompanied by a deterioration in cognitive function," said Stephanie Chevalier, lead author of the study at the McGill University Health Center. Executive functions are important in daily activities and behavior as they help maintain attention, think clearly, and make decisions. Decreased muscle strength negatively affects ... >>

USB4 version 2.0 03.09.2022

USB Promoter Group has announced USB4 version 2.0. Although the name hints that this is only a second generation USB4 upgrade, it supports double the data transfer speed of its predecessor, up to 80Gbps. The new standard will be backward compatible with USB4 version 1.0, SB 3.2, USB 2.0 and Thunderbolt 3, but not with USB 1.0 and Thunderbolt 4. USB4 2.0 specifications will be updated for USB Type-C and USB Power Delivery (USB PD). Due to licensing issues, USB and Thunderbolt were updated side by side. Intel laptops have a Thunderbolt port, while AMD Ryzen laptops have USB4 branding. However, even after Intel's upgrade to Thunderbolt 4, data transfer speeds were roughly equivalent to those of Thunderbolt 3 and USB4 1.0. With version 5, Ryzen-based laptops may have an edge, at least until Intel announces Thunderbolt 4. Brad Saunders, head of the USB Promoter Group, said: "Striving again in USB tradition, this updated USBXNUMX specification doubles the performance of ... >>

A flight to Mars will change the human body 03.09.2022

Space medicine experts from the Australian National University have developed a mathematical model to identify the difficulties that the human body will face during a flight to Mars. The algorithm made it possible to calculate the key changes in the cardiovascular system that can occur during a long flight of six to seven months. As a result of the study, scientists found that the main harm to the body will cause a long stay in microgravity. During a six-month flight, the structure of blood vessels and the cardiac system run the risk of significantly reorganizing under the new conditions of artificial gravity. In such an environment, blood is not attracted to the limbs, as it is with Earth's gravity. An astronaut's heart slows down because it doesn't have to pump as much blood as it does on Earth. But the rest of the body does not expect this, and the brain thinks that too much water has accumulated in the body, because the fluid is retained in the upper body. Defense mechanisms come into play ... >>

Found the relationship between musical taste and personality type 02.09.2022

Experts from the University of Cambridge conducted a large-scale study and found out that there is a relationship between preferred genres of music and personality type. More than 71 thousand people from 34 countries of the world took part in the experiment, who had to watch music videos and pass a personality test. As it turns out, extroverted people generally prefer contemporary dance music. But fans of the Nirvana group showed a tendency to neuroticism, that is, a condition characterized by emotional instability, anxiety and excitement. ... >>

Found an important difference between the human brain and other primates 01.09.2022

Scientists from Yale American University compared the activity of genes in the cells of the cerebral cortex in humans and other primate species. This made it possible to reveal a lot in common between them - and several important differences that can be key for the formation and operation of the human brain. Among these differences are microglial cells, which use the FOXP2 gene, which is important for language. Biologists led by Nenad Sestan investigated the structures of the dorsolateral anterior cortex (dlPFC) - an area closely associated with the work of language and emotions, short-term memory, decision making and other higher cognitive functions of the brain. dlPFC tissues from four primate species, humans, chimpanzees, macaques, and marmosets, were used. For each of them, scientists have identified a transcript - a complete set of RNA synthesized from active genes, showing which ones work in each particular cell. Thus, the authors received more than 600 thousand transcriptomes ... >>

Fast Charger for Smartphones 01.09.2022

The faster the smartphone charges, the faster you can start using it fully. Although the battery life of electronics has practically not changed in 20 years, since it has not yet been possible to increase the battery capacity by several times while maintaining the same size, however, experts have learned how to create chargers that can be charged by mobile devices in a matter of minutes. The record holder in this regard was Xiaomi, which has already invested several billion dollars in total in the development of new chargers that can charge smartphones at the highest possible speed. By 2030, the brand plans to teach its phones to charge in 1 minute to 100%, so that recharging the phone no longer takes at least some time.

The news is capable of delivering 20 watts at a current of 10,5 A, thanks to which a compatible smartphone will charge up to 100% in just 8 minutes. ... >>

Climate change causes bees to deform 31.08.2022

A team of scientists said that analysis of bee samples from across the UK showed that they all react negatively when the weather gets hotter and wetter. It turns out that bee wings become more jagged and asymmetrical when the bees are stressed. As one of the most important insects on the planet, they are under special threat, and therefore the food of people too. 75% of the world's 115 major food crops dependent on pollination are at serious risk. "Because hot and humid conditions are predicted to place more stress on bumblebees, the fact that these conditions will become more frequent due to climate change means that bumblebees may have a tough time in the 21st century," explained senior co-author Richard Gill. from Imperial College London. In doing so, scientists are trying to figure out how bees respond to specific climatic conditions and take action to help keep these insects healthy. "We hope to be able to predict ... >>

Atomic television 30.08.2022

NIST scientists demonstrate the use of Rydberg-state rubidium atoms as receivers that can receive live video and even play video games. A stable radio signal is applied to a glass container filled with atoms in the Rydberg state. The modulated output is then fed to a TV, where an analog-to-digital converter converts the signal into a video graphics array format for display. This work is part of the NIST on a Chip program. Researchers at the National Institute of Standards and Technology (NIST) have adapted their atomic radio to detect and display color television and video games. Atom-based communication systems are of practical interest because they can be physically smaller and more tolerant of noisy environments than conventional electronics. The addition of video can improve radio systems, for example in remote locations or in emergencies. The NIST receiver uses atoms prepared in high-energy ... >>

Users of online stores browse products more often than they buy them 30.08.2022

The share of visits to online stores that ended with the purchase of any goods is in the range of 1-2%, and in some states it is even lower. A new study has shown that online shopping is most often not shopping in the strict sense of the word. The fact is that in 33 out of 57 countries studied by experiments, the number of visits to online stores, during which users purchased any product, does not exceed 2%. In dozens of countries, this figure is even lower. In India, as well as in the countries of South America, the number of visits to online stores that ended in purchases of goods does not exceed 1%. The highest rates were recorded in the Netherlands (3%), the UK (2,9%) and Switzerland (2,6%). Despite this, the study clearly demonstrates that in most cases, Internet users are limited to browsing products on online platforms. ... >>

Larva meat substitute 29.08.2022

South Korean scientists have created a meat substitute from the proteins contained in the body of flour beetle larvae and sugar. These insects are usually used for laboratory experiments or as food for small animals. According to Professor of Wonkwan University in Iksan (South Korea) Cho Inhee, the increase in meat prices, as well as the problem of global warming, is forcing the modern world to seriously consider the possibility of eating various insects. "We hope that the method of processing flour beetle larvae developed by us will lead to the emergence of artificial analogues of meat and "meat sauces" based on these insects," the scientist expressed hope. ... >>

A new method for quantum entanglement of photons 28.08.2022

Physicists at the Max Planck Institute have developed a new method for quantum photon entanglement and demonstrated it by entangling a record number of light particles. This method can become a technological solution for creating quantum computers, writes Alternative Science. Quantum entanglement is a phenomenon that seems impossible to the everyday observer. In fact, the particles can be so intertwined with each other that they can no longer be described separately, and a change in photons and their properties instantly causes a response from the "partners", no matter how far apart they may be. The consequences of such a phenomenon worried even Einstein, who called it "spooky action at a distance." As counterintuitive as it may sound, quantum entanglement has been experimentally demonstrated for decades. This phenomenon even underlies new commercial technologies such as quantum computers, where entangled particles can be used to ... >>

Solar panels over water channels 27.08.2022

Last year, American scientists published a feasibility study on the benefits of building solar panels over water channels. Now it has become known that a Nexus pilot project is being implemented in California, in which solar panels will be placed over two spans of canals in the Turlock irrigation district to collect energy. California authorities have allocated $ 20 million for the implementation of the Nexus project. The construction of new power facilities above the canals is scheduled to begin in October this year. Solar panels will appear over the 150-meter span of the canal in Hickman. Similarly, the panels will be placed over a 1,6-kilometer canal span in another part of the state. "If it works for the first two miles of the Nexus project that we're implementing now, it could potentially spread to many places," said Josh Weimer, manager of Turlock Water & Power. The length of the California channels is about 6,5 thousand km. If they are all ... >>

Dogs also cry for joy 25.08.2022

For a long time it was believed that tears of joy or sadness are peculiar only to people and that animals do not cry. But now Japanese researchers have conducted a series of experiments involving man's best friend and found that dogs can also cry for joy. When reunited with their owners after a day's absence, dogs don't just whine with joy, they also cry with excitement, scientists say. Among 18 dogs, the researchers found a 10% increase in tear volume (compared to normal wetness) when the dogs greeted their owners. Tear drops were measured by placing an absorbent piece of paper over the dog's eye for 60 seconds and recording how far the moisture penetrated. It is positive emotions that cause additional tears in dogs. When a solution containing the "love hormone" oxytocin (also associated with feelings like trust, empathy and relationship building) was added directly to the eyes of 22 dogs in another experiment, the researchers found that ... >>

Fruit picking drones 24.08.2022

Fruit that rots on trees or on the ground costs farmers about $30 billion in sales a year. Fruit harvested even two weeks late loses 80% of its value. Now the main cause of lost production, sometimes in the form of fruit rotting right on the trees, is the global shortage of fruit pickers, which is estimated to grow to five million workers by 2050. Even today, more than 10% of all fruit in the world cannot be harvested - equivalent to the total annual fruit consumption in the entire European Union. Israeli startup Tevel Aerobotics Technologies has developed autonomous flying robots that fly from a base station, pluck only ripe fruits from a tree, and carefully lower them to be harvested. Because they are not human, Tevel assemblers can work XNUMX/XNUMX during the harvest. They never get tired, they never need to go out for coffee or the toilet, and they don't plan vacations. Works run on gas and electricity. Each FAR is equipped with an artificial ... >>

Sweet sodas make people dumb 24.08.2022

The consumption of soft drinks has increased significantly over the past decades, mostly cola-based soft drinks. Excessive consumption of cola-based soft drinks has been linked to a number of diseases and cognitive decline, especially memory impairment, according to a study by an international team of scientists. In addition, diets high in sugar can contribute to insulin resistance, metabolic syndrome, and dyslipidemia. So, in experimental rats, which were given cola-cola, memory and the ability to pass mazes worsened. Abnormalities in the frontal cortex and hippocampus of the brain associated with cognitive functions have been identified. Thus, the results show that long-term consumption of soft drinks leads to memory impairment and oxidative stress. Younger children may be more receptive to changes in soft drink behavior, the study suggests, but ... >>

Yamaha SR-C30A soundbar with compact wireless subwoofer 23.08.2022

Yamaha has announced the minimalist SR-C30A soundbar. The device is cheaper than the Sonos Ray analogue, which is considered the "measurement of quality" in the segment of low-budget soundbars.

People love naughty cats 23.08.2022

In a recent study, experts found that, in fact, the relationship between a cat and a person has a positive effect on people. One ironic reason is that some cat owners enjoy it when their pets misbehave. Cats can be little monsters, but some people love them for that. In a new study, experts looked at the psychopathic traits of domestic cats, including arrogance, meanness and disinhibition. This behavior can be annoying if a person behaves like this, but not a domestic cat. In total, the experts conducted 3 experiments and found that owners liked it when their cats showed disinhibition, such as jumping around carelessly, and also, oddly enough, unfriendly towards other pets. "In fact, these behaviors tend to encourage more frequent interactions between the cat owner and their emotional intimacy. That unfriendly behavior towards pets ... >>

Artificial cartilage is superior to real 22.08.2022

Scientists from Duke University (USA) have created the first gel-based cartilage substitute that is even stronger and more durable than real cartilage. The hydrogel is made from water-absorbing polymers. It can be squeezed and pulled with more force than natural cartilage and is three times more resistant to wear and tear. To make this material, the team filled thin sheets of cellulose fibers with polyvinyl alcohol - a polymer made up of thread-like chains of repeating molecules - to form a gel. Cellulose fibers act like the collagen fibers in natural cartilage: they provide tensile strength to the gel. Polyvinyl alcohol also helps him return to his original form. The result is a jelly-like material consisting of 60% water. It is flexible yet surprisingly durable. This material is attached to a titanium base, which is installed in place of damaged cartilage. Lab cartilage was 26% stronger than natural cartilage ... >>

Tired of thoughts 21.08.2022

You can get tired not only from physical work, but also from thoughts - not from some specific heavy thoughts, but from mental stress. Many people know that in the evening you think worse than in the morning, that in the evening it can be difficult to remember what you ate for breakfast today, not to mention planning the next day. Someone explains this by saying that the brain expends energy - and it really expends energy - and more energy is spent on complex mental tasks than on simple ones. Cognitive fatigue is a sign of brain exhaustion, and you can get rid of it by supplying the brain with food, such as glucose. But the energy hypothesis, despite its obviousness, was not experimentally confirmed. The brain consumes energy, but mental fatigue does not arise from this. Researchers from the Brain Institute in Paris, the Pitiers-Salpêtrière Hospital and the Sorbonne University write in Current Biology that the neurotransmitter glutamate may be the cause. Glutamate (glutamic acid) use the most p ... >>

Ultrasound makes the band-aid more sticky 21.08.2022

Researchers have found that they can control the stickiness of medical adhesives using ultrasonic waves and bubbles. The development will allow the patch to be applied, for example, to wet skin, according to McGill University (Canada). To make the adhesive stickier, the team experimented with the intensity of the ultrasound to create microbubbles in the adhesive. Ultrasound induces many microbubbles that push the adhesive against the skin for a stronger bioadhesion momentarily. With this method, scientists can, for example, precisely control the stickiness of medical patches or adhesive dressings on many tissues.

Researchers at the Georg August University of Göttingen in Germany have come up with a new way to preserve biodiversity using vanilla. According to the researchers, vanilla plantations established on fallow lands in Madagascar do not differ in yield from plantations established in the forest. In addition, cultivation on fallow lands also increases biodiversity in these areas. Growing vanilla in the forest rather than on fallow land resulted in a 23% loss of all species, and a 47% reduction in endemic species, the scientists say. The discovery of scientists will help restore the biodiversity of Madagascar. ... >>

Helping your child with homework is not helpful 19.08.2022

For decades, the scientific community has encouraged parental help and control over homework. Allegedly, the joint performance of school work has a positive effect not only on discipline, but also on the grades of children. Alas, American scientists in a new study dispelled this myth. US scientists used two datasets covering students in grades 1-5 in public and private schools. When analyzing the results, the socioeconomic status and education of parents were also taken into account. The results were very surprising - no relationship was found between parents' help with homework and the child's success in math or reading. Scientists have found that no matter how smart an adult or child is, whatever their socioeconomic status, and how much time is spent on textbooks, this is unlikely to have any significant impact on a child's academic results. In earlier studies, scientists have already asked what kind of help parents should provide in ... >>

The most powerful stable magnetic field 19.08.2022

Scientists from the Chinese Academy of Sciences at their High Magnetic Field Laboratory were able to break the world record by achieving a stable magnetic field strength of 45,22 Tesla. This is 45 thousand times more powerful than the magnetic field of a conventional refrigerator magnet. Chinese scientists managed to break the previous record for the strongest stable magnetic field, which was achieved by American scientists from the National High Magnetic Field Laboratory, USA in 1999. Then scientists with the help of their hybrid magnet achieved a magnetic field power of 45 Tesla. Both American and Chinese physicists continue their work to improve hybrid magnets to create powerful stable magnetic fields. The hybrid magnet uses two different ways to create a magnetic field: with an outer superconducting ring and with an inner Bitter magnet. Using these two technologies, you can create the strongest stable magnetic fields. Back in 2016, Chinese physicists approached the American ... >>

Improving the energy efficiency of existing wind farms 16.08.2022

Modeling and testing have shown that almost any wind farm can increase its energy efficiency if each individual turbine is operated as an integral part of the entire array, and not as a separate object. The technology was proposed by scientists at the Massachusetts Institute of Technology and is ready to broadcast it for any current and future wind farm projects. Today, wind turbines produce about 5% of electrical energy in the world. The vast majority of them are part of large wind farms with dozens or even hundreds of turbines whose air turbulences can influence each other. Obviously, if the mutual influence of turbines is taken into account, then the cumulative work of the entire field of wind generators can be optimized, which was studied by MIT specialists together with colleagues from other institutes. Looking ahead, we note that optimization by the totality of the influence of wind turbines on the generation of wind turbines ... >>

Found an effective way to cheer up 16.08.2022

Researchers from the University of Iowa conducted an experiment during which they found out a way to help quickly cheer up. Many people often experience depression, sadness and other negative emotions. But as it turned out, you can reduce this feeling and quickly cheer yourself up using a simple method. American psychologists conducted an experiment in which almost 500 students took part. They were divided into three groups and each was given one of the psychological exercises to test: Mercy, Connectivity, and Top-Down Social Comparison. The first psychological technique was that a person would mentally wish happiness to everyone he met. The second was to feel a connection with others, for example, imagine what feelings you might have in common with people you meet. And the third method suggested that participants look at passers-by with a sense of superiority over him. The experiment lasted 12 minutes, after which the students returned to their ... >>

Removing scratches from a car with sunlight 15.08.2022

The appearance of scratches on the car is inevitable. They spoil the overall look and you have to turn to specialists to eliminate them. However, thanks to the development of Korean scientists, everything will soon be possible to do independently and without much difficulty. Specialists have created an innovative tool that needs to be applied to a scratch and put the car in the sun. After half an hour, the scratch will disappear. According to the inventors, this material contains a polymer network based on acrylic polyol. Under the influence of infrared rays, a chemical reaction occurs, restoring minor damage at the site of application of the product. The regeneration process can be accelerated.

Shrimp shells will strengthen concrete 14.08.2022

Shrimp shell nanoparticles significantly improved the quality of cement. The technology will reduce fishing waste and carbon emissions. Researchers at Washington State University and Pacific Northwest National Laboratory have created tiny crystals and fibers of chitin from seafood waste. Nanoparticles increase the strength of cement by almost 1,5 times. Scientists have studied the behavior of chitin nanoparticles. Unlike cellulose, also used to increase the strength of cement, this material has an extra set of atoms at the molecular level. Thanks to this, scientists can control the charge on the surface of the molecules and, therefore, their behavior in the cement slurry. The study showed that adding processed chitin nanocrystals to cement improves its properties, including its consistency, setting time, strength and durability. They saw a 40% increase in concrete's flexural strength and an improvement in its ability to compress ... >>

Fish scale screens 14.08.2022

Scientists from the Nagoya Technological University in Japan have proposed a new way to create carbon nanoonions (CNO) - nanoscale carbon structures formed by nested carbon spheres. They were offered to be produced taking into account fish scales. The main substance that is necessary for nano-onions produced from scales is collagen. It can absorb the required amount of microwave radiation to rapidly increase the temperature, which, when heated, leads to thermal decomposition, which promotes the synthesis of CNO. Due to the excellent electrical and thermal conductivity of nanobulbs, they are used in biomedicine, bioimaging - a visualization method for real-time monitoring of the processes occurring in the body. Nanobulbs are also used in the production of panels for televisions and other electronics. The approach proposed by Japanese specialists does not require complex catalysts, harsh conditions, or long waiting times - the process takes ... >>

New waste disposal technology on the International Space Station 13.08.2022

NASA has successfully piloted a new waste disposal technology aboard the International Space Station (ISS) developed by Nanoracks, a Texas-based space equipment company. Typically, ISS astronauts spend months collecting garbage and storing it at the station, waiting for the Cygnus cargo ship to arrive. Cygnus is a spacecraft designed to transport supplies to the space station. After delivering supplies, the astronauts load bags of garbage onto the ship. When a spacecraft deorbits, it burns up completely upon re-entry into the Earth's atmosphere. The new concept developed by Nanoracks uses a specially designed waste container contained in the ISS commercial airlock module, the Bishop Airlock. Station crew members can fill it with approximately 270 kg of waste. After that, the container is separated from the module and, like Cygnus, completely burns out during entry into the Earth's atmosphere. This method is better because the astronauts should not expect to arrive. ... >>

Urbanista Phoenix TWS earbuds with built-in solar battery 13.08.2022

Following the release last year of Los Angeles on-ear headphones with integrated solar panels, the Swedish company Urbanista has prepared Phoenix wireless (TWS) headphones, which use similar Powerfoyle elements, which are also used in the previous version. However, in earplugs, the solar panels are not placed on the body of the earbuds themselves, but on the charging case. The Powerfoyle elements produced by Exeger are designed to extend the life of the headphones without recharging - Phoenix users will not be able to completely do without sockets. The TWS headphones themselves do not have integrated solar cells, they are built into the Phoenix case. Given the small size of the headphones, the decision is quite logical. But, if in the previous model of full-size headphones, the strip of solar cells placed on the bow is almost always directed towards the sun, then in Phoenix you need to make sure that the case is under the sun's rays. Phoenix provides up to 8 hours of operation due to its own ... >>

Growing wood without a tree 12.08.2022

American scientists from the Massachusetts Institute of Technology have invented a method for laboratory growing wood. To do this, the researchers first isolated cells from the leaves of young Zinnia elegans plants. The cells are cultured in a liquid medium for two days, then transferred to a gel-based medium that contains nutrients and two different hormones. Adjusting hormone levels at this point in the process allows researchers to fine-tune the physical and mechanical properties of the plant cells that grow in this nutrient-rich broth. The cell culture solution is then extruded into a specific shape using a 3D printer and left in the dark to incubate for three months. At the end, the material is dehydrated and sent for research. "The idea is that you can grow plant materials in exactly the form you want, without the need for any kind of mechanical processing that consumes energy and produces ... >>

Trap of eternal desires 10.08.2022

Research shows that people are constantly trying to get more and more things, such as a new smartphone, or clothes and shoes, although this does not always bring them happiness. American scientists have found out what explains such a desire for a large number of new material goods. "People constantly strive to be happy and often this happiness lies in material things. A person constantly needs more and more. But many people cannot achieve happiness in their imagination and this causes depression. Therefore, people fall into the trap of "eternal desires" when for to find happiness, they need more and more things. But as studies show, this does not always lead to the desired result and people become, on the contrary, unhappy. Our study explains why we continue this eternal struggle, although it negatively affects us, "says Rahit Dubey from Princeton University, USA. Scientists believe that our brains are programmed to have more and more ... >>

The earth is moving further and further away from the sun 09.08.2022

Scientists have found that the Earth is gradually moving away from the Sun. This will affect the fact that the amount of sunlight will gradually decrease. Due to the oval orbit of our planet, the distance of the Earth from the Sun can vary from 147,1 million to 152,1 million kilometers. Astronomer Brian DiGiorgio of the University of California at Santa Cruz believes that the distance between the Earth and the Sun is slowly increasing over time. There are two main reasons for this increase in distance. One of them is that the Sun is losing mass. The other has to do with the same forces that cause the ebb and flow of the tides on Earth. “Our Sun is predicted to have about 5 billion years left to live, but there will come a time when our star begins to slowly die, and before that, the Sun will lose about 0,1% of its mass. Although this does not seem much, but this figure is comparable to the mass of Jupiter, which is 318 times heavier than the Earth," the scientist said. Also, according to DiGiorgio, the Sun loses mass, when it ... >>

Iron mining on Mars 09.08.2022

Australian researchers at Swinburne University of Technology have developed a process to produce iron on Mars. They propose using concentrated sunlight as an energy source, and extracting iron from regolith using carbothermal reduction. Experiments on the Perseverance rover demonstrated the possibility of extracting oxygen on the Red Planet through the electrolysis of carbon dioxide (CO2). During this process, a large amount of carbon monoxide (CO) is released as a by-product. The researchers propose to combine the oxygen plant with the production of iron to use by-products. In their calculations, the scientists showed that the hot gas produced by the electrolysis of carbon dioxide would be rich in CO (91%). It can be used to preheat regolith. In addition, by condensing the monoxide, pure carbon can be obtained. The researchers analyzed the composition of ma ... >>

Photon nose for monitoring crops 08.08.2022

Experts from two British universities are embarking on a new project to develop a photonic 'nose' to monitor crops for pests and plant diseases. Aston University Birmingham is collaborating with Harper Adams University to research and develop technology to use light to monitor plant health. They will test the new technology on strawberries. After all, its berries are vulnerable to potato aphids, which can destroy the annual crop. In general, with increasing pressure to find alternatives to pesticides due to environmental and human health concerns, one method is to use Integrated Pest Management (IPM) to establish an early warning system. The point is to constantly make sure that insects and diseases do not accumulate on the plants, instead of spraying the plants with chemicals. However, there are doubts about the cost and reliability of this method. The new project uses ... >>

Mattress for fast falling asleep 06.08.2022

Engineers from the University of Texas at Austin have created a mattress with a set of electronic components that analyzes a person's condition and makes the temperature as comfortable and relaxing as possible for a person. Due to temperature fluctuations, the mattress quickly causes a feeling of drowsiness, and also immerses the user in a deep sleep. The level of alertness and sleepiness of a person is partly determined by the biological clock. This process is accompanied by changes in temperature in different parts of the body. Scientists decided to use this fact to create a system that tells the body when it's time to fall asleep. The mattress is a kind of manipulation, when the body believes that the temperature of the surrounding space is higher than it is. The mattress consists of several heated layers not evenly. The neck, arms and legs of users are heated slightly to increase blood flow to dissipate heat, while the torso is cooled for an additional relaxing effect. During the series of expert ... >>

Artificial vision system based on the body of a fiddler crab 04.08.2022

Current artificial vision systems have some limitations: they are not suitable for imaging both terrestrial and underwater environments and are limited to a hemispherical (180°) field of view. To solve these problems, a team of researchers from Korea and the United States, including Prof. Yang Min-song from the Gwangju Institute of Science and Technology in Korea, has developed a new artificial vision system. It is equipped with an omnidirectional imaging capability that can operate in both aquatic and terrestrial environments. The system was inspired by the fiddler crab (Uca arcuata), a species of semi-terrestrial crabs with a 360° field of view. It is possible due to the ellipsoidal stem of the compound eyes of the crab, which makes it possible to obtain panoramic images of amphibians. In turn, flat corneas with a graduated refractive index profile enable the crab to view images of amphibians. Accordingly, the researchers developed a vision system that consists of an array of flat microlenses with graduations. ... >>

Foods and drinks have become sweeter 03.08.2022

Using market sales data from around the world, Deakin University researchers analyzed the amount of added sugar and sweeteners in foods and beverages from 2007 to 2019. The study showed that the amount of sugar in drinks increased by 36% in all global markets, and in products - by 9%. "Men are recommended to consume less than nine teaspoons of sugar per day, while women are less than six. However, since sugar is added to many foods and drinks, more than half of Australians exceed the recommendations, eating an average of 14 teaspoons per day," the study says. Such a large amount of sugar and sweeteners consumed can lead to type II diabetes and increase the risk of cardiovascular disease. In addition, such a diet can disrupt the gut microbiome. Since foods and drinks are now sugary, their consumption is addictive. This is of particular concern for children who are still developing VC. ... >>

Dogs can see with their nose 02.08.2022

A new link between smell and vision has been discovered in the brains of these animals. Scientists believe it is this connection that gives dogs a keen sense of direction and awareness. Even when they can't see well, animals can fetch balls and sticks precisely because of the sense of smell that guides them. Dogs' strong sense of smell helps them detect and distinguish between objects and obstacles, even if they are completely blind. A new study provides the first evidence that dogs' sense of smell is intertwined with their vision and other parts of the brain. "We have never seen such a relationship between the nose and the occipital lobe, the functional visual cortex in dogs, in any species," said study author Pip Johnson, assistant professor of clinical science at Cornell University in Ithaca, USA. “When we enter a room, we primarily rely on our eyesight to determine where the door is, who is in the room, where the table is. Our study shows that dogs’ sense of smell helps them learn about their environment. ... >>

Power plant Bluetti AC500 & B300S 02.08.2022

The Bluetti brand announced the creation of a power plant with a capacity of 18 Wh. The name of the system presented the day before is AC432 & B500S. To launch a serial assembly, the developer decided to raise funds through crowdfunding. Users who invest in the novelty will receive the product at a promotional price.

For charging portable devices and at home ... >>

The influence of temperature on physical processes 01.08.2022

Biologists led by José Ignacio Arroyo, a postdoctoral fellow at the Santa Fe Institute, have presented a diagram that demonstrates how temperature affects living organisms. "The theory is fundamental," says SFI professor Pablo Marche, an ecologist at the Pontifical Catholic University, Santiago. "It can be applied to almost any process that is affected by temperature." Previous attempts to generalize the effects of temperature on biology lacked the "big" implications of the new model, Marquet says. Biologists and environmentalists often use the Arrhenius equation, for example, to describe the effect of temperature on the rate of chemical reactions. This approach explains a number of biological processes, but it does not take into account metabolism and growth rate. Initially, Arroyo wanted to develop a general mathematical model to predict the behavior of an initial variable in a conventional biological system. However, he quickly realized that temperature is a kind of universal predictor and can ... >>

Serotonin does not affect the development of depression 01.08.2022

Low levels of serotonin, also called the “feel good hormone,” are thought to cause depression. However, British scientists consider this approach too simplistic. And question the use of antidepressants. "Thousands of people are suffering from the side effects of antidepressants. But the number of prescriptions continues to grow," said study leader Joanna Moncrieff, professor of psychiatry at University College London. Scientists analyzed data from tens of thousands of patients, including both healthy and depressed patients. Experts compared the levels of serotonin and its breakdown products in the blood and brain fluids. It turned out that there was no difference in their levels between healthy and sick people. Research on the serotonin receptor and transporter has been very controversial. High levels of serotonin were observed in patients with depression. Experts attribute this to the fact that they are taking antidepressants that cause such an effect. As it turned out, change ... >>

Liquid Cooled TeamGroup M.2 SSD 31.07.2022

TeamGroup has officially unveiled its latest N74V-M80 series solid state drive, the main feature of which is a one-of-a-kind cooling system. This is the first M.2 drive in this area with evaporative chamber cooling, which will significantly increase the potential of the memory controller and in general. The mechanism of operation of the evaporation chamber is extremely simple - there is a liquid inside the case, which, when heated from a heat source (in this case, the memory controller of a solid state drive), releases steam, and it, in turn, gradually cools, releasing condensate on the walls of the evaporation chamber. This condensate is mixed back into the liquid flow, thereby starting a continuous evaporation process inside the element with heat dissipation. This is a more efficient cooling mode than conventional heatpipe designs that transfer heat to a heatsink. TeamGroup N74V-M80 developers went even further by combining two ... >>

Muscle building gene found 31.07.2022

Researchers from the Universities of Melbourne and Copenhagen have studied molecular responses in muscles before, during and after various types of exercise. The found gene will help discover alternative treatments even without exercise. To determine how genes and proteins are activated during and after exercise, the authors analyzed human skeletal muscle during exercise, said Dr. Benjamin Parker, lead author of the study. The team analyzed how the signaling responses in the muscles changed after different types of exercise, as well as how consistent these changes were in different people. Based on this, they identified a previously unrecorded C18ORF25 gene. He activated most of the time. To test it out, the team engineered mice without the gene. As a result, they had a deficiency of muscle fibers. This led to muscle weakness and reduced physical performance. Conversely, when they increased gene activity, the muscles were alive. ... >>

Wearable biosensors from old CDs 30.07.2022

As online music listening services become more popular, CDs are falling into disuse. However, some of them can still be used, since the gold foil contained in them can be used in the production of wearable biosensors. Although CDs are made primarily from polycarbonate, they contain a thin layer of foil. Most CDs have this aluminum foil, although some use gold. Because thin layers of gold are also used in flexible skin-attached biosensors, researchers at Binghamton University in New York asked if gold from discs could be used for this purpose. Under the guidance of graduate student Matthew Brown and Associate Professor Ahyon Koch, a method was developed in which gold CDs were first soaked in acetone for 90 seconds, which destroyed the polycarbonate, weakening the bond between it and the foil, then a sheet of polyimide adhesive tape was applied to the foil. which both foil and gold peeled off ... >>

Neurocomputer interface implanted in human 30.07.2022

The brain-computer interface has become a reality in the United States (albeit limited so far). Synchron says it has become the first company in the country to successfully implant a brain-machine interface into a human. Doctors at New York's Mount Sinai West Medical Center implanted a Stentrode device into the motor cortex of a patient who agreed to take part in the COMMAND experiment sponsored by Synchron. Its purpose is to evaluate the usefulness and safety of brain-computer interfaces in enabling people suffering from severe paralysis to control the device without using their hands. Ideally, Stentrode's technology should enable these people to self-send emails, text messages, and perform other digital tasks that healthy people take for granted. Surgeons installed the implant through an endovascular procedure, avoiding a major operation ... >>

Germany and the UK will be connected by a high-voltage cable 1,4 GW 29.07.2022

Another step has been taken towards the construction of a 1,4 GW high-voltage cable connecting Germany with the UK. A consortium of 20 lenders, led by the European Investment Bank (EIB), has agreed to provide €400m ($406,5m) for the NeuConnect interconnector project, a €2,8bn high-voltage DC link connecting Germany to the UK. "The investor consortium is led by French investor Meridiam, Allianz Capital Partners and Japan's Kansai Electric Power," the EIB said in a statement. There are other banks besides the EIB, notably the UK Infrastructure Bank and the Japan Bank for International Cooperation (JBIC). Construction on the project should begin before the end of this year, and completion is scheduled for 2028. The predominantly submarine cable will be 725 km long, with a power of 1,4 GW and a DC voltage of 525 kV. It will connect a Tennet-operated conversion station near ... >>

Collective intelligence in insects 29.07.2022

Scientists from Rockefeller University have found that ant colonies behave in the same way as neural networks during decision making. This was done using a new method of analysis, writes sciencedaily.com. Two researchers, Daniel Kronauer and Asaf Gal, set up an experimental setup to analyze decision making in ant colonies. They tested how the insects would behave in an extreme temperature increase for them. When each individual ant in the group feels hot underneath, it holds on as usual until the entire colony suddenly changes course. "They run out as one," the scientists say. "It's almost as if they had a large collective mind." The data obtained during the experiment indicate that the ants combine sensory information with the parameters of their entire group. So they make one decision at all. This process is similar to neural computing, leading to decision making in the same way. "For the first time we examined the moore ... >>

Blueberry crop improvement robot 28.07.2022

La Libertad is one of the regions producing and exporting more blueberries to Peru. However, the producers of this highly valued sour fruit in the world face a big problem: to determine the exact moment when the mass harvest of blueberries should begin. Errors in forecasts inflict many economic losses on the agro-industrial complex. With this in mind, the Labinm Robotics research team at the private university Antenor Orrego (UPAO) is developing a prototype robot that allows you to sample a bunch of blueberries and use algorithms and artificial intelligence to know when the fruit should be ready. “Agro-industrialists have their own harvest forecasts and therefore hire a lot of people for this period, but when the calculations do not work, you have to wait, and the cost of personnel and equipment still has to be assumed, which is why we decided to develop this prototype to give a solution,” said Sixto. Prado Garini, principal investigator at Labinm Robotics. The specialist stated that ... >>

Global Fresh Water Survey 28.07.2022

The Surface Water and Ocean Topography (SWOT) mission will survey more than 95% of the Earth's lakes, rivers and reservoirs. Researchers are able to measure water levels in only a few thousand lakes on the planet and have little to no data on the planet's important river systems. But this problem has been solved thanks to a collaboration between the French space agency Center National d'Etudes Spatial (CNES), involving the Canadian Space Agency and the United Kingdom Space Agency, according to NASA, which is also involved in the collaboration. The SWOT satellite is scheduled to launch this November from Vandenberg Space Force Base in California. Engineers and technicians are currently finalizing SWOT at Thales Alenia Space in Cannes, France. This will help to better understand the Earth's water cycle and contribute to better management of water resources, as well as increase knowledge about how climate change affects lakes, rivers and reservoirs. ... >>

Solid state optical nanodrive 27.07.2022

Engines of various types are a fairly common thing in our daily lives, they are present in cars, washing machines, computers and many other things. There are also tiny nanomotors that are used to power nanobots, microelectromechanical systems, and other devices that can only be seen under a microscope. However, most of the previously created flooders, especially those driven by light, are capable of operating only in a liquid medium, which significantly narrows the scope of their practical application. Researchers at the University of Texas at Austin have demonstrated a first-of-its-kind solid-state optical nanodrive that can be built into any device, even an electronic chip chip. This new tiny engine is less than 100 nanometers wide. It is a substrate made of a special energy-intensive material that changes its phase state (from solid to gas-liquid) under the influence of ... >>

Hydrogen production system from tap water without electrolysis 27.07.2022

Spanish scientist Jose Antonio G.I. developed a system capable of producing and storing hydrogen on site from tap water without costly electrolysis. The prototype consists of a water tank, initially filled with water, and two more chemical elements that the researcher does not want to reveal. Hydrogen production begins when a 20W compressor pumps compressed air into the bottom of the tank. "It is the air that causes the reaction between various chemical components and produces hydrogen," the scientist explained. "Then the resulting hydrogen exits through the top of the tank and enters a tank with the same pressure. The water in this second tank collects possible impurities, and the hydrogen exits through the top of the tank." After cleaning, the hydrogen flows through the upper pipeline to another tank equipped with closed contacts, a safety valve and an outlet pipe with a solenoid valve. "Now we are developing a model with a 220-liter tank ... >>

The influence of music on the state of memory 26.07.2022

Regular listening to music by older people has a positive effect on brain function and improves memory. This conclusion was reached by a group of therapists, neurologists and geriatricians led by Psyche Louis, director of the Music Visualization and Neural Dynamics Laboratory. During the study, volunteers aged 54 to 89 were asked to listen to a music playlist daily for an hour, tailored to their preferences. Participants of the experiment kept diaries describing their state of health and impressions. Scientists measured the parameters of brain activity for each musical session. Listening to music has been found to improve communication between the auditory sensory system and the brain structures associated with the reward system. Music sessions affected brain activity by touching the medial prefrontal cortex. It is known that a reduction in the volume of this zone leads to a violation of the perception of events, the development of depression, and in old age - to functional disorders inherent in ... >>

quantum flute 26.07.2022

American scientists have created a "quantum flute" that can make photons move in sync and interact with each other, something they almost never do in nature. The device could help improve future quantum computer designs. Like the musical instrument of the same name, the team's "quantum flute" is a piece of metal with a long cavity in the middle, accessed by a series of holes from the surface. But this device is designed not for sound waves, but for light. "Just like with a musical instrument, you can send one or more wavelengths of photons through it all, and each wavelength creates a 'note' that can be used to encode quantum information," said David Schuster, lead author of the study. In their experiments with the device, the researchers were able to control the interaction of up to five notes, or qubits, at the same time, using a superconducting electrical circuit as the master qubit. It shows, ... >>

Neural network sommelier 25.07.2022

Scientists at NIST have developed a new type of artificial intelligence (AI) hardware that can use less power and run faster - and it can already taste wines virtually. As with traditional computer systems, AI has physical hardware circuits and software. In hardware, there are usually a large number of conventional silicon chips that consume a lot of energy: for example, it takes about 190 megawatt-hours (MWh) of electricity to train one modern commercial processor. A less energy intensive approach is to use other kinds of hardware to create neural networks. One promising device is the magnetic tunnel junction (MTJ). Devices on MTJ consume several times less energy than their traditional counterparts. MTJs are faster because they store data in the same place where calculations are performed. The new neural network, like ordinary tasters, should train their taste. coman ... >>

Heart for biorobots 25.07.2022

American scientists have invented a rubber deformable pump that mimics animal biology and can serve as a "heart" for robots made of soft materials. Researchers at Cornell and the US Army Laboratories have developed a "circulatory system" center similar to the heart of biological creatures, designed to increase the mobility and independence of robots. The resulting "heart" is an elastomeric pump that works due to hydrodynamic and magnetic forces. Previously, similar pumps were already built into biorobots, but they were located outside, looked very bulky and allowed energy to be lost. The engineers managed to hide the new design inside, since it consists only of a soft silicone tube and coils of wire - solenoids, which are located around the device at a small distance from each other and allow the pipe to stretch and bend. In the tube, as conceived by the developers, a solid core of the magnet is also hidden, which operates according to the principle ... >>

Super glue that can withstand record temperatures 24.07.2022

Chemists at Tsinghua University in Beijing have developed a promising mixture for combining different items at extreme temperatures. The new adhesive withstands from -196 to 200 degrees Celsius and can be reused. The new adhesive will be useful in heavy industry and aerospace applications such as rockets that face temperature fluctuations. The new substance belongs to the class of supramolecular adhesives. The parts of the mix are specially designed to self-adhere into strong bonds during the curing process. The authors reported that one of the components is a ring-shaped molecule known as a crown ether, while the other is a small protein produced by bacteria. When the described components come into contact and the mixture is heated, the crown ether rotates the protein and securely fastens any surface. In a series of tests, the scientists glued two steel plates together and found that they could withstand up to 22 megapascals of force. At the same time, the glue worked not only at room temperature. ... >>

The sun makes men hungry 24.07.2022

To maintain a figure, men should be less in the sun. This was found out by the staff of Tel Aviv University. Analyzing the statistics of a large medical project that collected various data on three thousand people aged 25 to 65, the researchers found that during the warm season, men consume 17% more calories than women. The most obvious explanation here is that the sun somehow stimulates appetite, and only in men. Experiments with volunteers confirmed this: if men and women are specially brought out into the sun, and then asked how much they want to eat, it turns out that men feel more hungry after the sun. But women will not feel the difference - the sun does not excite additional hunger in them. Appetite and the feeling of hunger depend on many physiological signals, including the hormone ghrelin, which is called the hunger hormone. (In general, there are several hunger hormones, but ghrelin - ... >>

Electric tractors 23.07.2022

Indian startup Cellestial E-Mobility, a subsidiary of Tube Investments of India (TII) and Murugappa Group ventures, has officially unveiled India's first electric tractors. The startup developed three models of tractors with power from 27 hp at once. up to 55 hp The sale of electric tractors is planned within the next three months.

At the same time, the units have a PTO, hydraulics and all-wheel drive," the manufacturer said in a statement. Charging the battery of the electric tractor is carried out using a basic household charger from a conventional single-phase socket for 1 ... >>

Invisible solar cell suitable for window glass 23.07.2022

A team of scientists from Tohoka University (Japan) has created an almost invisible solar cell using indium tin oxide (ITO) as a transparent electrode and tungsten disulfide (WS2) as a photoactive layer. They published the results of the study in the scientific journal nature. It is noteworthy that the transparency of the solar battery reaches 79%. This will allow in the future to use these devices to equip "smart" homes, inserting them into windows instead of glass, to cover the screens of various gadgets like a smartphone and a fitness bracelet. The transparent solar panel will power wearable and mobile devices, saving people from having to carry a charger and depend on a power outlet. WS2 (tungsten disulfide) is a thin monolayer semiconductor composed of a transition metal and a chalcogen. According to scientists, this material is ideal for creating virtually "invisible" solar panels. Compound of indium tin oxide and tungsten disulfide (ITO-W ... >>

Air line for drones 22.07.2022

In the next two years, Skyway, the world's largest automated superhighway for drones and drones, will appear in the UK. The Skyway will be 263 kilometers long; the highway will unite Reading, Oxford, Milton Keynes, Cambridge, Coventry and Rugby. The cost of the project is 12 million pounds, and it is planned to complete it by mid-2024, writes the BBC. The technology will use ground sensors that are installed along the highway. They will be able to track the location of the drones in real time. This data is analyzed by an automatic traffic control system that will guide the aircraft and prevent them from colliding in the air. Chris Forster, COO of aviation technology company Altitude Angel, explains that such a highway could have many potential applications: ... >>

Plant pollination robot 21.07.2022

A group of researchers from Australia and Israel have been able to create a robot that pollinates plants. So, new technology can replace bees, as they may completely disappear from the face of the Earth by the end of the century due to global warming. The device is called "Polly". It is equipped with artificial intelligence that can detect ripe flowers and pollinate them by simulating air pulses. The installation already has a name - "Polly". The researchers note that over the past ten years, AI has significantly "smartered" as a result of improved deep learning from photographs. Now scientists are trying to figure out how to improve the efficiency of the robot so that it works in the conditions of South Africa and Australia. ... >>

Smart clothes that track posture and movement 21.07.2022

Clothing made of "smart" textiles, developed by researchers from the Massachusetts Institute of Technology, is able to reproduce the postures and movements of a person. To create models, scientists used a digital knitting machine. They wove a fabric from several rows of conventional and multifunctional piezoresistive yarns, which changes the resistance when compressed. The multilayer material, called 3DKnITS, was equipped with numerous motion sensors. Thanks to thermoforming technology, their accuracy has been significantly improved. Scientists noted that when moving, the layers of tissue are shifted and this distorts the performance of the sensors. To solve this problem, the researchers added thermoplastic threads to the material that begin to melt at temperatures above 70 degrees Celsius. Experiments have shown that such threads effectively fuse multilayer knitwear into one layer. The new technology makes it possible to produce products with complex shapes. Socks, e.g., exactly matched to the size of the user's feet ... >>

Computer vision for electric scooter 20.07.2022

Electric bike and scooter manufacturer and rental company Lime has announced plans to introduce Advanced Rider Assistance Systems. For this, a proprietary computer vision platform was created to detect sidewalk driving. In such cases, the user will be notified of the violation by an audible signal or by forcibly reducing the speed of movement. Lime will begin testing the new system on 400 scooters in San Francisco by mid-August. By the end of the year, it is planned to expand the pilot project to six cities, including Paris, where the company demonstrated the new technology for the first time. It is noted that in recent times, many large micromobility services have tried to implement some form of ARAS for scooters. Bird, Superpedestrian, and Neuron rely on location-based systems to track where users drive and park. Vo ... >>

Brain response to insults and compliments 20.07.2022

Words play a big role in human interactions. They can cause serious discomfort and pain, jeopardize reputation and pride. However, we still know little about exactly how the brain perceives hurtful words. Scientists from the Universities of Utrecht and Leiden (Netherlands) decided to look into this connection between emotions and language. The authors hypothesized that verbal abuse triggers a cascade of rapidly successive or overlapping information processing effects, and that repetition may affect different parts of this cascade differently. For example, some of them are able to quickly disappear with repetition, while others remain pronounced for a long time. The study involved 79 women. During the experiment, they read a series of repeated statements of three types: insults (eg, "Linda is terrible"), compliments ("Linda is impressive"), and neutral, factually correct descriptive statements ("Linda is Dutch"). To prove ... >>

Headphones that completely absorb background noise 19.07.2022

Researchers at the University of Washington (UW) have developed a prototype headphone that can provide the highest possible noise cancellation. Enthusiasts have created the ClearBuds headphones, which are equipped with active noise-cancellation features provided by artificial intelligence. According to experts, the machine learning system they have developed can eliminate extraneous sounds in headphones by almost 100 percent. The inventors showed how their headset allows you to almost completely eliminate extraneous sounds - the voices of people and the noise of a working vacuum cleaner. ClearBuds use dual microphones to capture external sounds, but the way they process signals is very different from other wireless headphones. According to inventor Maruchi Kim, during operation, each earbud creates two synchronized high-quality audio streams containing data about the direction of each enthusiastic sound. This method allows the AI ​​to create a spatial audio profile of the environment and ... >>

Diamond magnetic field sensor 19.07.2022

A team of researchers led by the Fraunhofer Institute for Applied Solid State Physics has developed a laser-based diamond sensor. The technology uses quantum defects in diamond (NV centers) to detect the magnetic field. The NV center or nitrogen-substituted vacancy is one of the many point defects in diamond. It is formed when the structure of the crystal lattice of the mineral is disturbed. When a carbon atom is removed from a lattice site, the resulting vacancy in this place is associated with a nitrogen atom. The researchers explain that the amount of light coming from the NV center varies depending on the strength of the magnetic field. This effect is already used by scientists, but in existing installations, most of this radiation is lost. “Our breakthrough was the creation of a defect laser. By collecting all the light, not just a small amount of it, we can detect the magnetic field 10 times more accurately with our sensor compared to current best practice,” says Andrew Greentr ... >>

Electric car Hyundai IONIQ 6 18.07.2022

The model is a sedan with the most aerodynamic "sloping" silhouette, its overall dimensions are 4855 x 1880 x 1495 mm (wheelbase - 2950 mm). Just like other brothers in the IONIQ line, the novelty is based on the proprietary Electric-Global Modular Platform (E-GMP) platform with support for 400/800V charging architecture. Buyers will be offered a single-engine rear-wheel drive RWD version or a twin-engine all-wheel drive AWD version. In the latter case, the Hyundai IONIQ 6 electric car will receive a power of 239 kW and a torque of 605 Nm, which allows it to accelerate to 100 km/h in just 5,1 seconds. It will also be possible to choose two battery options - 53 kWh or 77,4 kWh, a more capacious option will provide a range of 610 km on the WLTP measuring cycle. From a powerful 350 kW high-speed charge, it takes only 10 minutes to charge from 80 to 18% of the battery capacity. So ... >>

Gamers make decisions faster and more accurately 18.07.2022

American neuroscientists from the University of Georgia gathered a group of 47 young people, 28 of whom often played video games, and the remaining 19 rarely or never. Participants were placed in an MRI machine with a mirror inside that reflected a screen with moving dots. Volunteers had to press the button with the right or left hand, corresponding to the movement of the dot. Sometimes the point stopped - in which case the participant did not have to press the button at all. The scientists found that video game enthusiasts performed the task faster and more accurately than others. What's more, subsequent analysis of brain scans showed clear differences associated with increased activity in certain areas of the brains of gamers. There was no difference between the speed and accuracy of the response. Gamers were better at both. According to the researchers, in the future, computer games can be used as a tool for cognitive decision-making training based on visual perception. ... >>

GDDR6 memory chips 17.07.2022

Samsung announced the release of the industry's first GDDR6 memory chips with a data transfer rate of 24 Gb / s per pin. Such chips will be used in next-generation AMD and NVIDIA graphics cards, laptops, game consoles, and AI accelerators in data centers. The new memory chips will provide a 30% increase in data transfer speed compared to the previous version (18 Gb / s). Thus, a fully equipped graphics card will be able to provide memory bandwidth up to 1,1 Tbps. This is equivalent to transferring 275 1080p movies in one second. Unlike GDDR6X memory developed by Micron in collaboration with NVIDIA, Samsung's new GDDR6 memory is fully compliant with JEDEC specifications. The chips are also expected to be less power hungry due to the use of high-k metal gate technology. In addition, the new memory will run cooler than GDDR6X, provide better performance, and be cheaper to manufacture. ... >>

Perovskite solar cells 17.07.2022

Perovskite is an extremely promising mineral for the construction of solar panels. However, the main problem of such products is their short service life. Researchers from Princeton University in the US have finally tested in the laboratory a sample that can work without replacement for up to 30 years in real conditions. Although silicon has been the main material for solar panels for decades, perovskite has been actively gaining ground over the past 15 years. Perovskite is as efficient as silicon, but allows for less expensive, lighter and more flexible panels. However, perovskites are not very stable and are rather short-lived in real-world use. In the new study, the Princeton scientists added a special intermediate layer just a few atoms thick between the light-absorbing perovskite and charge-carrying layers to stabilize the structure. The intermediate layer is made of carbon disulphide, lead, iodine and chlorine and ... >>

Sensitive dark matter detector 16.07.2022

The world's most sensitive dark matter detector has begun scientific work after passing tests for 60 days. The facility is located at a depth of 1,5 km at the Sanford Underground Research Center in Lead, South Dakota. The sensitivity of the instrument is estimated to be 50 times higher than that of the previous setup. The device will collect event data for at least 1000 days without any guarantee of a result. When searching for dark matter, even a negative result is a step forward. The search in a certain range of masses and energies forces us to correct the physical model of this hypothetical particle, which has set the very foundation of our Universe. It is the particles, therefore, it is correct to change the tracing paper from the English "dark matter" in Russian to "dark matter". Matter can also be a field, this is a broader concept, and a particle, nevertheless, is a substance. The new LUX-ZEPLIN (LZ) experiment builds on the previous two, LUX and ZEPLIN, but is presented on a larger scale. Yes, if ... >>

A new way to obtain alternative fuel 16.07.2022

Scientists from the US Department of Energy's Berkeley National Laboratory, together with colleagues from the Danish Technical University, have developed a new method for obtaining alternative fuels. This substance is similar to biological diesel, which is created as a result of the metabolism of soil bacteria. While chewing food, bacteria synthesize molecules that reproduce a large amount of energy. In chemistry, anything that requires energy to produce releases energy when it breaks down. This makes it possible to release a large amount of energy, as when burning oil. True, like hot fuels, molecules have explosive properties. If you learn how to enrich the fuel at low temperatures, then rockets and airplanes will be able to fly on it. ... >>

The effect of light on mood disorders 15.07.2022

A new study from Brown University has shown how light affects a person's mood. The study was funded by the National Institutes of Health and the Alcon Research Institute Award, the Department of Biology and Medicine at Brown University, the Israel National Institute of Psychobiology, and the Canada Banting Fellowship. The team sought to determine if humans had a mood-regulating neural pathway that connects light-sensitive retinal ganglion cells in the eyes to the brain's prefrontal cortex (PFC). The study was conducted jointly with scientists from the Hebrew University in Jerusalem. Using functional magnetic resonance imaging (fMRI), the researchers were able to conclude that there is a functional relationship between light exposure and brain activity mediated by the prefrontal cortex. "The results of our study show a functional relationship between light exposure and cognitive and affective responses, based on ... >>

Growing plants in total darkness 15.07.2022

Biologists from the University of California have figured out how to completely eliminate sunlight and still accelerate the growth of plants. Using acetate as a carbon source, scientists have successfully grown several crops and food microbes in absolute darkness. The new approach turned out to be even more effective than the natural one - for example, the production of yeast without light accelerated by a record 18 times. The prospects for the technology are enormous, the authors argue - artificial photosynthesis will simplify farming in cloudy regions, it will also feed astronauts and colonizers of other planets. Despite the fact that photosynthesis has been the main process that stimulates plant growth for millions of years, sunlight has never been an ideal source of energy. On average, crops absorb only 3% to 6% of sunlight. By studying various salts and esters, scientists have concluded that acetate - the main component of regular vinegar - may work as a more effective ... >>

AI for fast drug discovery 14.07.2022

MIT researchers have developed the EquiBind deep learning model, which is 1200 times faster than peers to bind molecules to proteins to create drugs. Before developing a drug, researchers must first find molecules that can "dock" with specific target proteins. However, this process requires significant financial and computational resources. Moreover, it takes decades to develop and test a new drug, and 90% of discoveries fail, scientists said. According to the lead author of the study, Hannes Stark, existing methods of binding a ligand to a protein are like "trying to insert a key into a lock with a lot of keyholes." "Typical models are time consuming and evaluate each match before picking the best one. In contrast, EquiBind directly predicts the exact location of a key in one step without prior knowledge of the target protein pocket, known as "blind matching". ... >>

Current behaves like a liquid 14.07.2022

Researchers at the Massachusetts Institute of Technology have been able to experimentally confirm the quantum effect previously predicted by theoretical physics. It turns the electric current into the movement of waves, not particles. The experiment is based on the study of the properties of a material called tungsten ditelluride, which is characterized by high purity. Wave motion is characteristic of a liquid, where large molecules push each other and can create different eddies regardless of the direction of the main flow. However, the electrons are too small and therefore more affected by the environment than each other. In theory, an electric current can only be like a liquid under ideal conditions, such as absolute zero temperatures and materials of absolute purity. This is a very attractive target for engineers, since it opens up a new path to the creation of superconductors. A research group at the Massachusetts Institute of Technology was able to build a simplified model on which ... >>

The device is called Myoshirt, which works like a shirt - you just have to put it on. The technology is designed for people with disabilities. It increases strength and endurance by 60 percent. The shirt works like this: sensors located in the fabric send data to an intelligent algorithm. The algorithm recognizes exactly what movement the owner wants to make and what effort is needed for this. The developers assure that the user always keeps the situation under control. The support is dictated by his own movements. The shirt "turns off" easily, you can do it at any time. ... >>

It's raining in the bowels of the earth 13.07.2022

A few hundred kilometers from the earth's crust there is another ocean - magmatic. And its size, most likely, exceeds the area of ​​the rest, terrestrial. This hot ocean is made up of water molecules mixed with molten rocks. Previously, it was believed that the water from the underground reservoir does not come into contact with moisture from the Pacific, Atlantic, Indian and Arctic oceans. Denis Andrault and Nathalie Bolfan-Casanova, geologists at the University of Clermont in France, have come up with a new concept that suggests that water does indeed seep through the mantle into the world's oceans. Geologists called this phenomenon mantle rain. "Under the earth's crust there is a layer 410 kilometers thick, which contains many water molecules," explains Denis Andrault. Forty years ago, scientists believed that water molecules do not rise through the mantle and the earth's crust to the ocean, but only make their way back to the bowels of the Earth. If this were the case, then the oceans on the planet would slowly decrease, constantly ... >>

Crime Prediction Algorithm 12.07.2022

Sociologists at the University of Chicago have developed a new algorithm that can predict crime up to a week ahead. Thus, the algorithm studies patterns during the commission of crimes and their location based on open data on violent and property crimes. The model is assumed to predict crime with a 90 percent probability. In addition, researchers in the study found that police made more arrests in wealthy areas than in poor areas. The algorithm has already been tested in Chicago. The model divided the city into sectors and predicted the level of crime in each of them. ... >>

Construction of the largest enterprise for the direct removal of carbon dioxide from the air 12.07.2022

The Swiss company Climeworks has begun construction of the world's largest facility to remove carbon dioxide from the air. In September last year, Climeworks in Iceland launched the first Orca (Orca) plant with a capacity of 4 thousand tons of CO2 per year. The new Mammoth plant will be able to annually remove 36 thousand tons of carbon dioxide from the atmosphere, and it will start working in 18-24 months. The company recognizes that millions of tons of carbon dioxide must be removed from the air each year to offset CO2 emissions from human activities. Hundreds of thousands of Kosatka and Mammoth installations will be required to achieve the goal. This is what Climeworks aims to achieve by 2050, expecting a long and difficult road to solving the problem of climate neutrality. Carbon dioxide extracted from the air is mixed with water and pumped into cavities in the earth - mines and natural reservoirs. This is being done by the contractor represented by CarbFix. Usually mineralization (binding) of carbon dioxide in nature ... >>

Found a way to increase the efficiency of solar power plants 11.07.2022

Scientists from Stanford University in the USA have developed a cheap lens for solar panels that can collect up to 90% of the light and increase its brightness by 3 times. Passive Axially Graded Index Lenses (AGILE) solar technology can help reduce the footprint of solar power plants. Solar energy will play an important role in meeting sustainable future energy needs. The technology could help install solar panels in small areas where it was not possible before. AGILE does not require solar tracking and respects the maximum limit of the cosine projection by concentrating light falling on it from all angles. With AGILE, pointless concentration systems (i.e. without having to follow the Sun) can be used, which reduces the amount of photovoltaic material as well as efficiently absorbing stray light. After all, the scattering of light due to cloud cover and the atmosphere can reach 20% even on a sunny day. AGILE M Concept ... >>

Consciousness exists separately from the brain 11.07.2022

A new study shows that consciousness can function even when the brain is damaged. Scientists have proven that under extreme conditions, the human mind functions separately from the brain, even if it is damaged. University of Vienna professor Alexander Battiani, who studies consciousness, has done a great job of studying about a thousand cases, which are often called near-death experiences. The most revealing Battiani considers those cases where the injury was more severe. The fact is that these people could see more than those who did not receive serious injuries. More than half of the people who survived clinical death saw much more than the rest. In another study, 74% of the subjects were more aware of what was happening. ... >>

Biodegradable implant cools nerves and relieves pain 10.07.2022

American researchers have presented a biodegradable implant in the form of a nerve tape, which blocks the transmission of pain signals due to the cold. Tests on rats have shown that the implant successfully cools the nerve to 10 degrees Celsius, reducing sensitivity to mechanical irritation and gradually dissolves safely in the body. The application of ice or other cold to the damaged area has long been known and used to reduce pain. It works, in part, by reducing the speed and magnitude of the nerve impulse, that is, preventing the transmission of pain signals from the peripheral nerves to the brain. This usually occurs at temperatures below 15 degrees Celsius, but prolonged local exposure to cold can cause tissue damage. In an effort to maximize the effect of a pain relief method with a minimum of adverse reactions, Northwestern University scientists and colleagues have developed a cooling nerve implant that blocks the transmission of pain. ... >>

Drought-resistant rice genes found 07.07.2022

Chinese scientists have discovered two genes in rice that could make China's mainstream crop more heat-tolerant, providing a new way to breed highly heat-tolerant crops. Researchers from the Shanghai Institute of Plant Physiology and Ecology of the Chinese Academy of Sciences and Shanghai Jiao Tong University have uncovered the mechanism by which the rice cell membrane senses external heat stress signals before binding to chloroplasts. This is the organ where photosynthesis takes place to provide resistance to heat. Too high a temperature can damage the plant's chloroplasts. When the temperature exceeds the normal tolerance of a crop, its yield tends to decrease. Specialists identified a locus with two genes: Thermo-tolerance 3.1 (TT3.1) and Thermo-tolerance 3.2 (TT3.2). They interact with each other to increase the heat tolerance of rice and reduce grain yield losses caused by heat stress. Scientists have found that the accumulation of TT3.2 causes ... >>

World's largest bacterium discovered 06.07.2022

The world's largest bacterium has been discovered in Caribbean mangrove swamps - so big it can be seen with the naked eye. The thin white filament, about the size of a human eyelash, is "by far the largest bacterium known to date," said Jean-Marie Folland, a marine biologist at Lawrence Berkeley National Laboratory and co-author of the paper. Olivier Gros, co-author and biologist at University of the French West Indies and Guiana, discovered the first specimen of this bacterium, named Thiomargarita magnifica, or "magnificent sulfur pearl", clinging to sunken mangrove leaves in the Guadeloupe archipelago in 2009. But he did not immediately realize that it was a bacterium due to its surprisingly large - these bacteria average a third of an inch (0,9 centimeter) in length. Only later genetic analysis showed that the organism is a single bacterial cell. "This is an amazing discovery," said Petra Levin, a microbiologist from Washington ... >>

Earth's lakes are evaporating faster than thought 06.07.2022

Scientists from the University of Texas said that the Earth's lakes are evaporating much faster than thought. And this evaporation plays a much larger role in the hydrological cycle than expected and has a significant impact on climate and weather modeling. Natural and artificial lakes occupy approximately five million square kilometers of the Earth's area. They contain about 90% of fresh water and are home to an amazing variety of organisms. But the increase in temperature and solar radiation associated with changes in cloud cover adversely affects the lakes. Decreasing ice cover also means that large areas of water are exposed to sunlight. All this together leads to an acceleration of the water cycle, from accumulation on land to dispersion in the atmosphere. Previous estimates of this process have been based on evaporation rates, but these estimates alone are not sufficient to reflect the net loss of lake water due to other factors, ... >>

Yeast can filter lead 05.07.2022

Inactive yeast may be a cheap and effective way to remove lead contamination from drinking water sources, according to a new analysis by scientists at the Massachusetts Institute of Technology (MIT). Research shows that this approach can be effective and cost effective, as just one gram of yeast can remove up to 12mg of lead in less than five minutes! A team of experts calculated that the yeast discarded from one brewery in Boston was enough to clean up the city's entire water supply. Lead and other heavy metals in water are a major global problem that continues to grow due to e-waste and emissions from mining. Unlike organic pollutants, most of which can eventually be broken down, heavy metals do not biodegrade but are stored in water indefinitely and accumulated by living organisms. In addition, they are either impossible ... >>

Facial similarity increases trust between people of the same sex 05.07.2022

A new study has found that people are more likely to trust their money to people with similar facial features. Scientists at Osaka University used a neural network trained in face recognition to find a relationship between physical similarity and trust. The results of the study showed that among same-sex interlocutors, people trust more those who are similar to them. When interacting with representatives of the opposite sex, such a connection was not found. For their experiment, the scientists formed a sample of 200 faces of students. All participants were photographed in full face with a neutral expression without glasses and accessories. The researchers also assembled a group of 30 volunteer evaluators who did not know anyone from the original base. The evaluators were shown randomly all the photos from the set for 0,5 s. They had to rate how much they would trust money to that person on a scale of -3 to +3. The researchers used the pre-trained ArcFace AI system to determine ... >>

Device for fighting pornography 04.07.2022

A group of Chinese scientists have unveiled a device designed to combat pornography banned in the country. It analyzes the impulses of the human brain. They make it possible to determine when a user is viewing porn. The innovative gadget was tested on 15 male volunteers. During the experiment, they were shown various content. As it turned out, the human brain reacts to pornography in a special way. Scientists have recorded the impulses provoked by pornographic content. The device they created gives a signal when the human brain begins to generate the same impulses. Pornography in China is prohibited at the legislative level. Sites on the global network are monitored by censors. The developers claim that the device they have created can significantly facilitate the work of censors. If, during work, due to fatigue, they miss prohibited content, the device will immediately let them know about it. ... >>

PET plastic from biomass waste 03.07.2022

Scientists at the Federal Polytechnic School of Lausanne (EPFL, Switzerland) have successfully developed a biomass-derived plastic similar to PET that can replace it and is more environmentally friendly. "Essentially, we're just 'cooking' wood or other non-edible plant material, such as agricultural waste, in low-cost chemicals to make a plastic precursor in one step," says Professor Jeremy Lutherbacher, who led the study. "By preserving the structure of the sugar in the molecular structure of the plastic, the chemistry is much simpler than existing alternatives." According to the new method the team used, adding an aldehyde can stabilize certain fractions of plant material and prevent them from breaking down during extraction. With it, the researchers were able to recreate a new beneficial bio-based chemical as a precursor to plastic.Using glyoxylic acid instead of formaldehyde, ... >>

Airbus helicopter on green fuel 03.07.2022

Airbus became the first aircraft manufacturer to fly a helicopter powered by both engines on 100% sustainable aviation fuel (SAF), typically derived from bio-materials, including used grease, vegetable oil and other degradable waste. The H225 was powered by Safran Makila 2 engines. The recent flight is in line with Airbus's commitment to certification of commercial airliners and helicopters running on green sustainable fuels by 2030 and is on track to achieve a 50% reduction in carbon emissions without compromising flight quality. In November, the company was already testing a similar helicopter, but at that time only one engine was running on the SAF. In addition, in March 2022, she tested the A380 Jumbo Jet airliner, one of whose engines also ran on eco-fuel. The main goal is not only to prove the ability of engines to use such fuel without design modifications, but also to evaluate ... >>

artificial photosynthesis 02.07.2022

Scientists are developing artificial photosynthesis to make food production more energy efficient on Earth, and perhaps one day on Mars. Researchers at the University of California at Riverside (USA) used a two-step electrocatalytic process to convert carbon dioxide, electricity and water into acetate, the form of the main ingredient in vinegar. Food-producing organisms consume acetate in the dark to grow. "Through our approach, we sought to define a new way of producing food that could overcome the limitations of biological photosynthesis," said author Robert Ginkerson, assistant professor of chemical and environmental engineering at the University of California, Riverside. To bring all the components of the system together, the scientists optimized the power of the electrolyser to support the growth of food organisms. Electrolyzers are devices that use electricity to convert raw materials ... >>

Benefits of Brewing 01.07.2022

It turned out that beer is not only a revered drink and a way to express one's political position, but also a potential support for the environment, namely, an inexpensive way to remove lead from water. This conclusion was made by specialists from the Center for Bits and Atoms at the Massachusetts Institute of Technology (MIT). In particular, scientists have found that inactive yeast can be an effective and inexpensive way to remove lead from drinking water sources. Studies have shown that 1 gram of this yeast can remove up to 12 milligrams of lead in less than 5 minutes. What's more, because the yeast cells used in this process are inactive and dry, they don't require much care, unlike living biomass, which requires nutrients and sunlight to keep the materials active. Scientists have calculated that the spent yeast thrown away from one brewery, for example, in Boston (USA), is enough to clean the entire water supply of the city. ... >>

quantum integrated circuit 30.06.2022

Australian developers reported significant progress in the development of quantum computers. Based on almost 20 years of scientific work by Australian teams, a young company from Australia - Silicon Quantum Computing (SQC) - was able to create the world's first quantum integrated circuit. The chip is able to simulate the behavior of just one molecule - polyacetylene, but it does it much better than classical computers. Designed and manufactured in Sydney, SQC's Quantum Processor is an analog solution for simulating the quantum states of molecules. The company still only dreams of a real quantum processor with the ability to correct errors. But even the molecular simulator promises a breakthrough for the field once such chips are commercially produced. A quantum chemical compound simulator will help you discover unusual materials and substances for pharmaceuticals and industry. Now we cannot even imagine what properties ... >>

A new way of skin rejuvenation 30.06.2022

Scientists at the Haifa Institute claim to have found a way to make the skin of an elderly person young again - with the help of laboratory rodents. The research was carried out by Dr. Aviad Keren, Dr. Yaniv Keren, Prof. Yehuda Ulman and Prof. Amos Gilhar of the Haifa Institute. By transplanting old skin into young mice, they proved that it was possible to make the skin and other organs look young again by changing the molecular structure in all layers of the skin. The team had previously transplanted aged human skin into young SCID mice, but they didn't know if the skin rejuvenation they observed extended below the epidermis. To determine this, they used vascular endothelial growth factor A (VEGF-A) to stimulate the rejuvenation of human organs in laboratory animals. When old human skin was transplanted into young SCID mice, aging was reversed, confirming that all layers of human skin can become young again. Cro ... >>

AI will help Meta achieve realistic sound in virtual worlds 29.06.2022

Meta Company spoke about the work on realistic sound technologies for virtual worlds - the project is being implemented with the assistance of scientists from the University of Texas at Austin. As part of the project, three artificial intelligence models were developed that are available to third-party developers. As Kristen Garuman, professor of computer science at the University of Texas and director of research at Meta AI, explained, augmented and virtual reality cannot be reduced to only visual component - sound plays an important role in bringing the world to life. Its quality is influenced by various factors: the geometry of the room, the objects placed in it, as well as the distance to the source. Therefore, the idea was born to use artificial intelligence algorithms for sound processing. The first algorithm is called AviTAR, a "Visual-Acoustic Matching Model" that transforms sound according to the environment. To explain how the algorithm works, the authors of the project gave an example. mother poset ... >>

Coffee reduces the risk of liver disease 29.06.2022

An international team of scientists has brought good news about coffee, with a recent study showing how the beloved beverage is associated with impressive health benefits, such as a reduced risk of liver disease. Researchers often find that coffee consumption is associated with lower blood sugar levels, improved cognition, protection from age-related dementia, and even longer life. All these relationships are correlational, not causal, but it is absolutely certain that coffee can at least improve our mood from 8 am to noon. A new study has focused on why our bodies feel so good from coffee (and tea, which also contains caffeine). In most scientific papers on the effect of coffee and tea on human health, it is the correlation that is indicated. It would not be superfluous to find out the details, scientists from the Netherlands, Great Britain, Germany, France and the USA decided. They looked at epigenetic changes, i.e. influence on the genes of external factors (in this ... >>

Sensor for biometric breath authentication 28.06.2022

Today, a person can be identified by a fingerprint, iris or face, but progress does not stand still, and Japanese scientists offer a new method of authentication. They developed a biometrics system based on a sensor that recognizes people by the composition of the exhaled air. Combined with machine learning technology, this "artificial nose" is nearly 98% accurate. In the age of digital information, biometrics is an important way to protect valuable data. In addition to the already familiar fingerprints and palms, voices and faces, there are also less common options: through the veins on the fingers or electrical brain waves. “All of these methods are based on the physical uniqueness of each individual, but they are not completely reliable. Physical characteristics can be copied or even broken by trauma,” explained Chayanut Jirayupat of Kyushu University, one of the researchers. “Recently, a new class of biometric authentication has emerged that uses a unique chemical composition for personal identification ... >>

Eternal laser 28.06.2022

Scientists have created an atomic laser that can last forever, unlocking the potential of next-generation technology for commercial use. Unlike conventional optical lasers, atomic lasers are made from something known as a Bose-Einstein condensate (BEC) of atoms that emit beams of matter. They require a lot of energy to hold and maintain their supercooled state, meaning that until now they could only be fired for a short time. "In previous experiments, the gradual cooling of atoms was performed in one place," said Prof. Florian Schreck, who led the study. - "In our setup, we decided to distribute the stages of cooling not in time, but in space: we make the atoms move while they go through successive stages of cooling. In the end, ultracold atoms get to the center of the experiment, where they can be used to form coherent waves of matter in BEC, but for now these atoms are used, but ... >>

200MP Samsung ISOCELL HP3 sensor 27.06.2022

Samsung has announced a new 200-megapixel image sensor called ISOCELL HP3, which has record-breaking small pixels of just 0,56 microns, which is 12% smaller than its predecessor. The Samsung ISOCELL HP3 will offer faster autofocus and better HDR thanks to a new image overlay algorithm. The new sensor comes nine months after the ISOCELL HP1, which is technically the first 200-megapixel sensor for smartphones, although there are no smartphones with it on the market yet. Since then, Samsung has been able to reduce the pixel size from 0,64 microns to 0,56 microns, and the optical format is now 1/1,4 inches, about 20% smaller than its predecessor. The technology of combining information from four neighboring pixels allows you to take high-quality 50-megapixel photos. For photos at night, there is support for 16:1 binning and 12,5 megapixel photos. Samsung also showed off its new autofocus solution ... >>

After a hard day at work, people speak faster and louder. 27.06.2022

At the end of a busy day at work, people start talking faster and louder due to the way stress affects breathing. These conclusions were reached by German scientists in the course of a study involving 111 people aged 19-59. Volunteers during the week assessed how difficult the working day was, and recorded their evening conversations on a dictaphone. Analysis of audio recordings showed that tired people after stressful situations in the evening begin to pronounce words faster. This is because stress activates the sympathetic nervous system. Because of this, bronchodilation occurs - the airways open and the person begins to breathe more often. This increases the speed of speech and the volume of the voice. ... >>

Special electrodes for battery operation in cold weather 26.06.2022

It is known that temperatures below the freezing point of water have a very detrimental effect on the basic parameters of lithium-ion batteries. In the context of electric cars and other vehicles, this means shorter travel distances, longer charging times, problems with regenerative braking systems, and more. Therefore, engineers and scientists involved in the development of new batteries pay great attention not only to increasing their capacity, but also to ensuring uninterrupted operation in extreme temperatures. Some automakers, notably Ford, equip their car batteries with temperature sensors and heaters that keep the battery temperature within acceptable limits. At the same time, part of the battery energy is spent on heating them, which reduces the travel range of an electric car.

The pollution of the planet with plastic waste is an increasing problem, so humanity is trying to get rid of oil-based packaging, replacing it with something biodegradable. Scientists from the USA offer a replacement for cling film. The promising technology belongs to scientists from Rutgers University. They have developed a plant-based, biodegradable coating that can be sprayed onto food. The resulting film will protect against pathogens and damage during transportation. This packaging is reported to extend the shelf life of tested avocados by 50 percent. The new packaging technology uses fibers based on biopolymers and polysaccharides. Like a web, the fibrous material can be spun with a hair dryer-like device and wrapped around products of various shapes and sizes. The resulting material is strong enough to protect against the ingress of foreign liquids and solids, and also contains ... >>

Monkeys love music more than movies 25.06.2022

Scientists in Scotland and Finland have developed "animal versions" of Spotify and Netflix and have given monkeys the ability to turn on multimedia on their own. It turned out that the primates would rather listen to Arctic Monkeys than watch Planet of the Apes - they liked the music more than the movies. The experiment took place at the Helsinki Zoo. It was attended by three pale saki - monkeys living in Brazil, Guyana, Suriname and Venezuela. In three interactive zones of a special enclosure, scientists have placed infrared sensors. In this room, the primates could turn on a video or sound track on the screen. They were reproduced until the pale saki themselves turned them off. It turned out that the monkeys included audio files twice as often as visual ones. That is, they preferred to listen to music rather than watch movies. Among video files, primates more often chose scenes with the underwater world - they were competed with videos with worms and abstractions. Among the audio tracks, the most popular was human-written music, not noise ... >>

Insects found to eat Styrofoam 25.06.2022

The intestinal microflora of zofobus can decompose inert polystyrene foam. Insects can only eat this material, it will not affect their growth and development in any way. Scientists from Australia have found that zophobus larvae can foam. By itself, this material decomposes very slowly, and therefore pollutes the environment. Polyfoam is widely used in construction as a heater. However, its waste is highly toxic. As one of the authors of the study, Christian Rinke, said, during the experiment, scientists studied the condition of the zophobus larvae for three weeks. One group was fed on bran, and the second group was fed on Styrofoam. There was also a third group that was not fed at all. It turned out that the insects that consumed the foam behaved and looked completely normal. Some of them even gained weight. This suggests that the larvae can absorb organic matter from the foam. ... >>

A window that produces electricity and heat energy 24.06.2022

Scientists at the Hong Kong University of Science and Technology have developed a dual-band selective solar energy harvesting (SSH) window based on transparent photovoltaic cells (TPV) and transparent solar absorbers (TSA). TSAs are used to convert ultraviolet (UV) or near infrared (NIR) light into thermal energy. The collected thermal energy is extracted by ventilated air to provide space heating in the cold season or to reduce the load on the cooling of the premises in the heat. The SSH window has an apparent transmittance of 42%, a solar conversion efficiency of 0,75%, and a solar conversion efficiency of 24% with a 10°C increase in ventilated air temperature. The research team used a luminescent solar concentrator (TPV) based on copper, indium and zinc sulfide (CuInS2/ZnS) quantum dots (QDs) as the outer window. It is able to collect ultraviolet ... >>

Coffee hurts shopping 22.06.2022

People spend a lot of money while shopping, not only because they do it on an empty stomach and do not make a list, but also because they use caffeine. If you're trying to cut down on impulse buying, a new study by experts has found that you should definitely refrain from drinking coffee. A study by the University of South Florida found that caffeine affects not only what you buy, but also how much money you spend when shopping. The team of scientists conducted the experiment in retail stores, an industry that increasingly adds coffee shops near entrances. In their study, experts found that shoppers who drank a cup of caffeinated coffee before going shopping spent about 50% more money and bought almost 30% more goods than those who drank decaffeinated coffee or water. During the experiment, scientists installed at the entrance of retail stores and home improvement stores in France and in the uni ... >>

Male and female perception of colors 21.06.2022

You can often hear the statement that men and women see things differently. It turned out that this is literally true. Scientists have found that depending on gender, a person can see color more or less bright. For example, if the spouses look at the color orange, it will seem redder to the man than to the woman. Experiments conducted at the City University of New York show that it is also difficult for men to notice subtle differences in shades of yellow, green and blue. These discoveries were made as a result of experiments in which both sexes were shown flashes of light and had to name the shade they saw. According to the researcher, Professor Israel Abramov, the difference in perception does not lie in the structure of the eye. The answer to this question lies in the activity of the brain. Male and female brains process information received as a result of contemplation in different ways. The study also showed that women are better ... >>

Foam instead of conditioner 20.06.2022

An innovative solution for lowering the indoor temperature was proposed by a group of German and Chinese scientists. They have developed a special foam with a high thermal insulation capacity. In the near future, the era of air conditioners may end. A huge trend in industry will not be applied, so it will cease to exist. Joint research by German and Chinese scientists led to the development of climate-adapted foam. The foam is made from modified wood and contains cellulose in the form of nanocrystals. The substance has the property of not transmitting sunlight, and due to its thermal insulation ability, it reflects the absorbed heat into the atmosphere. During the experiments, scientists applied foam to a cardboard box and placed it on a street site on a hot day. After some time, the air temperature in the box was measured and found to be 9,2°C lower than the outside air temperature. After confirming the effect ... >>

Ultra-recycled foods shorten life 20.06.2022

Researchers from the University of Paris set up an experiment. They analyzed data from tens of thousands of people aged 45 and older who reported their diet every day for seven years. During the experiment, scientists found that the use of ultra-processed foods causes premature death. Such products are those that contain food additives: flavors, colors, sweeteners and emulsifiers. This includes all fast food items. Ultra-processed foods have been on the rise over the past few decades and could lead to an increase in deaths from non-communicable diseases. ... >>

Mining platinum on asteroids 19.06.2022

American startup Astroforge wants to become the first company on Earth to master the mining of minerals in space. The startup, which has just emerged from stealth mode, is working on a technology to extract resources from asteroids with a diameter of 20 meters to 1,5 kilometers, according to TechCrunch.

Reusable and erasable ink 19.06.2022

A group of researchers from the University of Riverside has developed an ink based on titanium nanocrystals. They darken due to ultraviolet light and disappear due to oxidation by oxygen. During the experiments, the authors created patterns and printed text. Recordings were made by hand and with a laser pen. In each of the options, a contrasting pattern was obtained, which lasted for several hours. It is possible to extend the life of such ink by coating it with a protective layer of non-toxic polymer. The technology will be useful in areas where reusable surfaces are in demand or where information needs to be rewritten many times - on transport tickets, coupons and special scoreboards. ... >>

Up to 25% of employees are prone to workaholism 18.06.2022

In the 1970s, American psychologist and religious preacher Wayne Edward Oates coined the term "workaholism" and defined it as "an obsessive or uncontrollable desire to work." According to the International Labor Organization, about 8% of the working population works more than 12 hours a day, and American and Asian studies show that 10-25% of workers are prone to workaholism. Germany is in the top 10 countries that suffer from workaholism more than others. Partly because of this, it boasts not only the most powerful economy in Europe, but also an extremely low unemployment rate. At the same time, Germans know how to maintain a perfect balance between work and personal life. Research by the Hans Beckler Foundation has shown that a third of Germany's active population works "too much" and 10% tend to workaholism. Scientists studied data from 8000 employees of German companies collected between 2017 and 2018, just before the start of the coronavirus pandemic. ... >>

New biomaterial to replace human bones 17.06.2022

The research team has discovered a biomaterial based on cobalt and chromium that mimics the flexibility of human bones and has excellent wear resistance. The new biomaterial is proposed to be used for the manufacture of implants, for example, for arthroplasty of the hip or knee joints and bone plates. To date, most metallic biomaterials are stiffer than human bones and their use as implants results in bone atrophy, a condition in which bone density is reduced due to the destruction of bone substance and structure. And biomaterials with increased flexibility lose their wear resistance. The authors focused on reducing the gap in Young's modulus between metal implants and human bones. When a material is flexible, it has a low Young's modulus. When it is stiff, Young's modulus is high. New biomaterial based on Co-Cr has a low Young's modulus (10-30 GPa), almost the same as human braids ... >>

Fiber optic data transmission record broken 16.06.2022

For the first time in the world, scientists transmitted data over a conventional fiber optic cable at a record speed of 1 petabit per second. This is evidenced by the results of research by the National Institute of Information and Communication Technologies (NICT). A petabit is equal to a quadrillion bits (a number followed by 16 zeros), which is exactly the throughput that engineers at the Network Research Institute have been able to achieve in a 15-mode optical fiber with a standard jacket diameter (0,125 mm) using only four strands. Data was transmitted at a rate of 1,02 petabits per second over a distance of 51,7 km. The previous record was 610 terabits per second in a similar fiber, only then the researchers used part of the S-band (the frequency range of decimeter and centimeter wavelengths used for terrestrial and satellite radio communications), and now they have covered all frequencies. The new technology will significantly speed up the work of the Internet and quite soon, because it is compatible with existing ... >>

Artificial intelligence controls the tanker 15.06.2022

Hyundai's HD division, Hyundai Heavy Industries, organized the world's first transoceanic voyage of a large autonomous gas tanker. This technology made it possible to do without human intervention in control during a journey of several thousand kilometers, according to Korea Times. During the experiment, the ship covered 10 kilometers autonomously during a voyage from Freeport on the southern coast of the Gulf of Mexico to South Korea's Boryeong terminal. The flight was operated by SK Shipping, a division of the diversified concern SK Group. According to the developers, in the future it is planned to introduce autonomous systems not only on commercial cargo ships, but also on small-tonnage entertainment yachts. So far, in the testing mode, the vessel had a crew on board, but people did not interfere with the operation of automation at all throughout the entire 10 km of autonomous navigation. ... >>

Cable Power Specification for HDMI Cables 15.06.2022

The HDMI Forum has published an amendment to the HDMI 2.1a standard describing Cable Power technology. With its help, accessory manufacturers will be able to get rid of external power supplies and other "crutches" when transmitting data over long distances without losing signal quality. Modern HDMI cables have an implicit length limit of 3 meters to view content requiring full 48Gbps bandwidth without compromising signal stability or picture quality. When using longer accessories, as a rule, additional power adapters with a USB connector are used. The new Cable Power specification allows additional power (up to 5V/0,3A) to be delivered directly through the accessory itself. Separate devices or connectors are not required - the power supply will be provided by the signal source itself (for example, a game console or media player). It is noted that the function will only work in one direction. The user came ... >>

battery life extension gadget 14.06.2022

The American corporation Batteroo Corporation, under the leadership of the holder of a doctoral degree in electrical engineering, Bob Ruparvar, has developed a device called the Batteriser. The invention could deal a major blow to the $3,4 billion disposable battery industry in the US alone. The exclusivity of the invention is emphasized by the fact that not so long ago the office of the Batteroo Corporation was attacked, during which the prototypes of the invention and data carriers were stolen. Fortunately, Ruparvar has already managed to patent a proprietary technology that will significantly increase the efficiency of disposable batteries. The fact is that such batteries usually create a voltage of 1,5 V, which is required to power small devices, but as soon as the voltage drops to 1,35-1,4 V, many devices recognize the battery as discharged. And up to this point, only 20% of the battery resource is consumed. The invention of Batteroo Corporation will increase ... >>

Solar sails for spacecraft 14.06.2022

A NASA-funded project is developing a new technology that would allow spacecraft to be powered by "solar sails". NASA has announced that it will provide $2 million to the Diffractive Solar Sailing project, which is exploring ways to use solar energy to drive and power vehicles in space. The agency has long been interested in solar sail technology because it offers a cost-effective alternative to traditional propulsion without requiring fuel. In fact, ships could use an almost inexhaustible resource for power - sunlight. Previous "solar sail" designs have mostly used mirrored surfaces to reflect light particles. When photons hit the sail, they transfer their energy and propel the spacecraft forward. This method, however, has disadvantages: the ship can only move in the direction of sunlight. To get around this, the Diffractive project ... >>

Coffee drinkers have a lower risk of early death 13.06.2022

A British study published in the Annals of Internal Medicine suggests that people who drink coffee, with or without sugar, have a lower risk of premature death. However, experts say, the results may be due to the fact that coffee drinkers are more affluent. The study is based on data from over 171 participants in the UK BioBank, a long-term study that has collected data on the genetic, lifestyle and health information of over 000 people since 500, including details on participants' coffee drinking habits. Over seven years, those who drank 000 to 2006 cups of the drink a day without sugar had a 2,5% lower risk of death than those who didn't. Previous research has shown that the drink may have health benefits, and drinking coffee is associated with a lower risk of diseases ranging from chronic liver disease to certain types of cancer and even dementia. In addition, scientists observed a decrease in the risk of death among participants, ... >>

The robot will be used for diagnostics, as well as for biopsy - transporting drugs to the right places in the body. It is noteworthy that the robot can lift loads that are three times its size. The robot is based on a ferromagnetically elastic sheet body. Also included are cylindrical ring-shaped pads with hydrogel spikes. ... >>

Siberian tundra under the threat of destruction 12.06.2022

Even if global warming could be drastically curtailed by reducing emissions, only a part of the northern Russian biome, including the island of Taimyr and most of the Palearctic, could survive. If current greenhouse gas emissions are halved by 2100, only 2500% of the Siberian tundra will remain in 5,7. This conclusion was made by two German scientists Stefan Kruse and Ulrike Hertzshu from the Institute of Polar and Marine Research. Alfred Wegener after developing a climate model (named LAVESI) specifically designed to predict the changing relationship between the Siberian tundra and taiga. The tundra is characterized by permafrost, poor animal diversity, and low vegetation, including shrubs, mosses, and lichens. The very cold average temperature does not allow many trees to grow, with the exception of willows and birches no more than a couple of meters high. Taiga, on the other hand, is a boreal forest located south of the tundra and consisting mainly of large coniferous trees, such ... >>

Biological clock switch 12.06.2022

Experts from the Netherlands and Japan have been able to create a light-controlled kinase inhibitor switch that affects the biological clock. All cells in the body have their own clock, which can be tracked by fluctuations in the production and breakdown of proteins. If these rhythms are disrupted, a person can get sick. In addition, the change of time zones also negatively affects the body. However, biologist Tsuyoshi Hirota, assistant professor at the Institute, has developed a kinase inhibitor, longdaysin, that can slow down circadian rhythms by up to 48 hours. The development received a switch that activates and deactivates connections. The new device can shift the biological clock and equalize the circadian rhythms in the body. Scientists believe that the tested and improved version of the device will be used in the treatment of patients in serious condition. ... >>

Axial Higgs mode 11.06.2022

Researchers from Boston College (USA) have discovered a new particle - the so-called axial Higgs mode. Materials containing this particle can serve as quantum sensors to evaluate other quantum systems and help answer pressing questions in particle physics. Ten years ago, scientists discovered the Higgs boson - and this discovery was key to understanding mass. Other particles have also been theoretically predicted, including the axial Higgs mode. These theories were intended to explain "dark matter," the nearly invisible material that makes up most of the universe but only manifests itself through gravity. While the Higgs boson was discovered in experiments at the Large Hadron Collider, a new particle was found literally on the table. The team used a quantum material such as rare earth tritelluride (RTe3), which can be studied at room temperature in a "benchtop" experimental format. RTe3 has properties that ... >>

Found the coldest place in the solar system 11.06.2022

The coldest place on Earth is the eastern part of Queen Maud Land in Antarctica. Here, in some remote areas, temperatures can drop to minus 92°C. However, there are places outside of our planet that make Dronning Maud Land seem like an incredibly warm place. Uranus is the coldest of the eight planets, with an average temperature slightly lower than that of Neptune, although it is closer to the Sun than Neptune (The solar system does not always follow logic). The average temperature on Uranus is minus 195°C, while on Earth it is 14°C. However, outer space is a rather spacious place, so it is quite logical to assume that Uranus is not the coldest object in the solar system. Indeed, the piercingly cold ice giant is one of the least hospitable places in the solar system. Such temperatures, combined with the fact that Uranus has an atmosphere made up of helium, hydrogen and methane, means that nothing can survive there. Tem ... >>

Nanosensor detects pesticides on fruits 10.06.2022

Swedish scientists have developed a tiny sensor that can detect pesticides on fruit in just a few minutes. The technique uses flame-sprayed nanoparticles made of silver to amplify the signal of chemicals. The new nanosensors use surface-enhanced Raman scattering, or SERS, a powerful detection technique that can magnify the diagnostic signals of biomolecules on metal surfaces by more than a million times. This technology has been used in several areas of research, including chemical and environmental analysis, and for the discovery of biomarkers for various diseases. However, high manufacturing costs and limited lot-to-lot reproducibility have so far prevented wide application in food safety diagnostics. Researchers at the Karolinska Institute have created a SERS nanosensor using flame spraying - well proven ... >>

3D printing of wood 10.06.2022

Researchers from the Massachusetts Institute of Technology have learned how to synthesize a wood-like material for furniture and similar products in the laboratory. It can be used in 3D printers to create a wide variety of objects. This is supposed to solve the problem of deforestation. Mass cutting down of trees entails irreparable consequences for the planet and all its inhabitants. Scientists have figured out how to reduce the demand for wood by offering a cheaper alternative. The process is similar to growing animal cells as synthetic food meat. In the created woody plant material, properties such as weight and strength can be easily adjusted as needed. The team isolated cells from the leaves of Zinnia gracilis and then cultured them in a liquid medium for two days before transferring them to a thicker, gel-based medium. The material contained nutrients and two different plant hormones, the levels of which could be regulated. ... >>

Controlling things with the power of thought 09.06.2022

Now telekinesis, the movement of objects with the power of thought at a distance, is in the minds of many something from the realm of science fiction. But Chinese scientists are actively working to make this phenomenon a reality. Scientists at the China Air Force University of Engineering have taken the first step towards remote control of metamaterials using human brainwaves in a new study. Metamaterials are man-made materials that have unusual physical properties, including electromagnetic properties, that do not occur naturally. The two-dimensional analog of metamaterials are metasurfaces, which have unprecedented freedom in controlling electromagnetic waves. According to scientists, it is possible to create programmable metasurfaces with different functions that can be controlled remotely using the human mind. It is well known that the human brain creates brain waves in the process of thinking. Scientists have suggested that with the help of brain waves, which can ... >>

Smart pillow 08.06.2022

Chinese scientists have developed a self-powered "smart" pillow that will better understand the causes of lack of sleep, as well as track patients with diseases that affect head movement. Research has linked chronic sleep deprivation to diseases such as diabetes and heart disease, as well as mental health problems. People who want to better understand what happens to them at night can take a sleep test at a medical institution, or use an application for a smartphone or smart watch. As a more accurate alternative to the second method, scientists are developing new sleep monitoring systems using triboelectric nanogenerators (TENG) - a constant current source. These self-contained systems have already taken the form of eye masks, belts, patches and even sheets. And now the shape of the pillow. To design a new "smart" pillow, the researchers developed a flexible porous polymer triboelectric layer. Movement between the head and this layer changes the electrical ... >>

brain temperature 08.06.2022

Scientists from the Laboratory of Molecular Biology of the Medical Research Council in Cambridge were able to measure the temperature of the human brain. Forty volunteers aged 20-40 years were recruited, whose brains were scanned in the morning, afternoon and late evening using magnetic resonance spectroscopy. At the same time, an activity monitoring device was attached to the wrist of the participants in the experiment, which makes it possible to take into account differences in genetics and lifestyle - the biological clocks of "owls" and "larks" work differently. The temperature of the organ varies depending on the region of the brain, age, gender, time of day and the menstrual cycle in women. The average brain temperature was 38,5 degrees, more than two degrees above the temperature measured under the tongue. The surface of the brain was generally colder, while the deeper structures of the brain were often warmer than 40 degrees (the record during the study was 40,9 degrees). The temperature of the brain constantly changed depending on time ... >>

Computer in Orange Pi 800 keyboard 07.06.2022

The company, which has previously released a number of Orange Pi single-board computers, introduced its first computer in the Orange Pi 800 keyboard.

Earth's inner core is moving in different directions 07.06.2022

Scientists from the University of Southern California, USA, have found evidence that the Earth's inner core is moving in different directions, which contradicts accepted theories, which suggested that the core constantly rotates at a higher speed than the surface of the planet. A new study shows that our planet's inner core is changing speed and direction of rotation, as well as moving, as seismic data show. "We think that the surface of the Earth is shifting relative to its inner core, and also that it rotates more slowly than the planet and can rotate in a different direction," says John Vidale from the University of Southern California. The Earth's inner core is a hot, dense ball of solid iron about 2600 km in diameter. It cannot be seen directly, so scientists have used seismic data to learn about the speed and direction of its rotation, as well as its movement in the center of the Earth. In the 90s of the last century, scientists suggested that internal poison ... >>

Causes of senile smell 06.06.2022

Studies conducted by Japanese scientists have proven that human skin after forty years of age begins to release chemical compounds with an unpleasant odor. Previously, it was thought that the peculiar smell of old age is caused by poor hygiene, but it turned out that this smell is produced by the skin, releasing certain chemicals in the skin as it ages. Japanese scientists conducted research and found that hormonal changes after 40 years produce the production of the chemical compound 2-nonenal. It is formed during the oxidation of unsaturated fatty acids. As skin ages, it produces more fatty acids as its natural free-radical defense function deteriorates. And hormonal changes, such as menopause, further enhance this process. Given the peculiarity of the substance 2-nonenal, which does not dissolve in water, daily baths and hygiene procedures do not help get rid of the specific smell. A healthy lifestyle will help to reduce the excretion of noneal, as well as ... >>

Teleportation repeater for quantum internet 06.06.2022

A group of scientists from the Delft University of Technology in the Netherlands has presented the basis for the quantum Internet - a teleportation relay for indirect transmission of quantum states over a distance. During the experiment, a quantum state was transferred between two not directly connected network nodes without data loss, which was an important step towards creating a quantum internet. A team led by Ronald Hanson created a network of three nodes, each of which was a pair of qubits - one for storing state and the second for communication. The spin of the nucleus of the carbon atom in diamond was responsible for the preservation of the quantum state - it was a "memory" qubit, and the spin of the electron in each pair was used to transfer the quantum state to other nodes of the network. Then the electron spins of two neighboring directly connected nodes (B and C) were brought into a state of quantum entanglement. This means that the quantum state of one qubit depended on the state of the other. confusing ... >>

Quantum sensor for measuring the intensity, polarization and wavelength of light 05.06.2022

A team of researchers from Yale University and the University of Texas at Dallas have created a tiny quantum optical sensor that is about one-thousandth the size of a human hair. But, despite such a small size, this sensor has the widest possibilities, using the quantum properties of electrons, it is able to simultaneously measure the intensity, polarization and wavelength of light. The creation of such a universal sensor will allow in the future to make significant breakthroughs in the fields of astronomy, health care and remote sensing. In recent years, scientists have found that twisting or otherwise deforming certain materials can, in some cases, give those materials certain properties that they do not normally possess. In this case, the scientists also used such a method, applying it to a two-layer graphene, which was called TDBG (twisted double bilayer graphene). Twisting gra ... >>

Cosmic ray clock synchronization 04.06.2022

Geophysicist Hiroyuki Tanaka of the University of Tokyo put forward the idea of ​​simultaneously synchronizing clocks around the globe using cosmic rays. The principle is simple, he says, and the technology to do it already exists. Atomic clocks can keep accurate for decades, but they are expensive and difficult to synchronize in remote areas. Synchronization by satellite signals also has problems in the regions of the poles, under water and in the mountains. Hiroyuki Tanaka proposed a new method - space time synchronization (CTS). It is based on the use of so-called extensive air showers arising from cosmic rays entering the atmosphere. These rays create a "shower" of various particles, including muons flying towards the Earth at near-light speed and therefore reaching the earth's surface at the same time. By fixing their arrival, CTS devices can synchronize with each other in real time. "The principle is simple, but the technology, the sensor ... >>

Good deed ransomware virus 03.06.2022

CloudSEK cybersecurity experts spoke about the GoodWill hacker group, which distributes a ransomware virus, but in order to decrypt the data, it requires the victim not to pay a ransom, but to do good deeds. For example, donate blankets to the homeless, feed starving children with fast food, or pay for treatment for the poor, capture all this on photos and videos, and then post them on social networks. According to experts, the ransomware operators work from India - this is indicated by their emails and IP addresses assigned to Mumbai, to which the virus accesses. In addition, in one of the lines of code, an entry was found in "Hinglish" - a mixture of Hindi and English. The malware is written in the .NET framework, compressed with the UPX executable file packer, and data on infected Windows machines is encrypted using the AES algorithm. After infecting the victim's PC, the GoodWill virus encrypts files of various formats on it and offers to do three good deeds to decrypt them: donate clothes or blankets to "those in need on the road ... >>

Greenhouse vodka 03.06.2022

The American Air Company introduced a vodka called Air Vodka made from captured carbon dioxide. Another component of the drink is water. This is just one of several new products that use CO2 emissions that can be captured in various industries. “We have partners that we work with. They capture carbon dioxide before it goes into the atmosphere. We then use that carbon dioxide in the process of creating alcohol. With every bottle we make, carbon dioxide that would have been released is removed into the atmosphere and I think it's very good for our planet," says Gregory Constantine, co-founder of the Air Company. The production of alcoholic beverages in the traditional way leads to the release of carbon dioxide into the atmosphere. American scientists have found that the production of one bottle of alcohol with a volume of 0,75 liters leads to the release of approximately 3 kg of carbon dioxide into the atmosphere. Making vodka is traditional ... >>

Smart glasses and implantable chips instead of smartphones 01.06.2022

Pekka Lundmark, CEO of telecommunications equipment company Nokia, said that the commercial use of the sixth generation (6G) communication networks will begin in 2030. At the same time, he noted that by that time, most likely, many people will refuse to use smartphones, preferring wearable electronics and implantable chips. During a speech at the World Economic Forum in Davos, Lundmark said he expects commercial use of 6G around 2030. He noted that even before that, people are likely to abandon smartphones and switch to smart glasses and other similar devices that can connect to the Internet and interact with each other. Moreover, some of these devices will be implanted in the human body. “By then, the smartphone as we know it today will definitely no longer be the most common interface. Many of these things will be built right into ... >>

Jackdaws vote before flying to a new place 30.05.2022

Usually, flocks of jackdaws suddenly break away from their perch and fly away after a short roll call in raised tones. It turned out that the loud cries of birds are a form of "democratic" decision-making. The birds discuss whether it is worth leaving their homes, come to a consensus, and only then all together soar into the sky. These conclusions were made by scientists from the University of Exeter. They recorded calls in a colony of jackdaws and then experimented with the birds. "After spending the night in a large group, each jackdaw will have his own opinion about when to fly away. It depends on various factors: the size of the birds, hunger, and so on. At the same time, it is important for birds to reach a consensus, since a joint flight from a perch has benefits such as protection from predators, the ability to find a mate, and access to food information," explained study lead author Alex Dibnah. As the decision is made, the cacophony in the colony grows. After the required number of votes has been received, the birds raise en masse ... >>

statins for depression 29.05.2022

Statins are prescribed for those who have high levels of "bad" cholesterol, that is, low-density lipoproteins, which increase the risk of atherosclerosis. Statins have a number of side effects, but sometimes unexpected advantages are also found: two years ago we wrote that they suppress COVID-19, and just two or three months ago we said that statins prevent certain malignant tumors from metastasizing. Oxford researchers have discovered another unreported bonus that statins may have - they protect against depression to some extent. The authors of the work studied the psychological state of more than two thousand people for almost a year. They assessed their memory and emotional background, checked how they react to rewards and how well they recognize emotions on other people's faces. At the same time, the majority of study participants did not take any drugs, 4% took only statins, another 6% - drugs for high blood pressure, and another 5% - both statins and drugs for pressure together. od ... >>

The smallest remote controlled robot 29.05.2022

Scientists at Northwestern University in Illinois (USA) have demonstrated the smallest remote-controlled robot, the dimensions of which are only 0,5 mm in all axes. With its tiny dimensions, the machine can walk, jump, turn and curve - without the use of hydraulics or electricity. The mechanism is based on an alloy with a shape memory effect, which, when creating a structure, is deformed using a thin coating of glass. When heated, the alloy returns to its original shape, and when cooled, the glass coating re-deforms. Heating is carried out using a laser, and due to the miniature size of the mechanism, heat dissipates very quickly: up to 10 cycles in 1 second. The direction of the laser beam determines the direction in which the robot moves, and its average speed is about half the length of the body per second. The authors of the project experimented with several forms of mechanism, including a tripod capable of walking on water, a spiral ... >>

Living cells are extended onto the robot skeleton 28.05.2022

As a rule, living cells are grown under static conditions: only petri dishes and miniature 3D scaffolds are needed. It has previously been proven that tissue can also be grown on moving structures such as hinges. However, they stretched or flexed the fabric in only one direction. But researchers from the University of Oxford and robotics firm Devanthro decided that the best way to create tissues that can move and bend is to recreate their natural growth environment as closely as possible. Therefore, a team of scientists decided to imitate the human musculoskeletal system with the help of a robot. The scientists adapted the skeleton of an open source robot and created a special environment for growing cells (bioreactor) on it so that they bend and stretch in all the right directions. For this, the shoulder joint was chosen. The researchers then created a bioreactor that can be placed on an artificial shoulder using biodegradable threads stretched between two anchor points like a tuft. ... >>

Chimpanzee language 28.05.2022

Chimpanzees use a fairly rich language to communicate, scientists from the Max Planck Institute for Evolutionary Anthropology (Germany) concluded. "Our results suggest that the chimpanzee's vocal communication system is much more complex and structured than previously thought," the researchers said. As it turned out, in the language of primates there are sounds - "words" that animals are able to build in vocalizations - "sentences". The researchers had to analyze more than five thousand sounds that were made by wild chimpanzees in the Tai National Park in Cote d'Ivoire. As a result, scientists were able to identify 390 unique vocal sequences. Moreover, the chimpanzees exchanged them quite consciously. A large number of grunting, squeaking and puffing sounds were used for greetings, expressions of submission, messages about food, and so on. Depending on the situation in which the monkey found himself, the sounds differed. When alone, at the sight of food, a chimpanzee emits a cork. ... >>

Drone wolf pack 27.05.2022

In the United States, the military came up with and tested a new tactic for using combat drones. The tests took place at the Dugway Proving Ground near Salt Lake City, Utah, as part of the EDGE22 exercise, which involved the Future Vertical Lift cross-functional team and nearly 20 divisions and organizations from around the world. The military has been gathering for the second year to try out new tactics and technologies related to vertical takeoff devices. One of the promising new tactics has become the so-called "wolf pack", which is designed to replace the tactics of "bee swarm" when controlling drones. During the experiment, the UAVs were organized into four "batches" of seven each. Drones were equipped for reconnaissance, search, identification and transmission of information about enemy positions. The "swarm" tactic involves launching many drones with the same task - this requires high network bandwidth and sometimes leads to an overload of autonomous algorithms. In the case of the "wolf pack" appa ... >>

Scientists succeeded in synthesizing a decanter 26.05.2022

For more than a decade, various groups of scientists have tried with varying degrees of success to synthesize a new material, a form of carbon called graphyne, which is similar in many ways to the well-known graphene. And only recently, researchers from the University of Colorado at Boulder have developed a technique that allows you to perform the synthesis of a carafe with a guarantee of the result. This achievement will allow in the near future to more thoroughly study the properties of the decanter, which has prospects for its use in the fields of electronics, optics, nanotechnology, etc. In nature, there are several ways in which carbon atoms can bond with each other and form different forms of carbon, allotropes. According to the possibilities of creating chemical bonds, carbon hybrids are designated as sp2, sp3 and sp. For example, the most common graphite is sp2 carbon, while the less common diamond is sp3 carbon. However, the existing methods of chemical synthesis allow, without any trials, ... >>

The influence of genes in the formation of aesthetic taste 26.05.2022

Possession of aesthetic taste is usually determined through a person's preferences and his own opinion about specific objects of art and culture. Despite a long-standing interest in the origin of taste and much research on the causes of individual differences in the "concept of beauty", sociologists still know little about the mechanism of preference formation. In a new study, scientists from the University of Copenhagen (Denmark) assessed the contribution to the development of cultural preferences of family education, individual experience of a person, as well as his genes. To investigate this issue, they conducted a survey among 1200 Danish twin pairs, 466 of which were monozygotic (homozygous or identical) and 734 were dizygotic (heterozygous or polyzygotic). Based on the results of the survey, the researchers determined the twins' preferences for 12 cultural events, divided into three categories: high-intellectual, low-intellectual and popular cultures. Twin studies - good ... >>

Road junction at the bottom of the ocean 24.05.2022

A tunnel was built in the Faroe Islands, which will now connect the two largest islands of the archipelago. There are 18 islands in total, only one is uninhabited, all the rest are inhabited by local residents. The issue of road communication is considered one of the key ones. The name of the tunnel, which is distinguished by the presence of a roundabout at a depth of 180 meters in the Atlantic Ocean, is Esturoyartunnlinn. This is not the first underwater tunnel. Prior to that, in 2002, the same tunnel, the length of which was 4,9 km, connected the islands of Streymoy and Vagar under water. Another 6,2 km long tunnel was opened in 2016 and connected the islands of Esturoy and Bordeaux. The current tunnel is 11,2 kilometers long and consists of three roads. That is why a roundabout was needed. In November of this year, its construction and finishing was completed, and the tunnel itself is planned to be put into operation ahead of schedule - December 19. After commissioning, the tunnel in the Faroe Islands will officially become the second longest in the world. ... >>

Tomato produces vitamin D 24.05.2022

Researchers at the John Innes Center (UK), together with colleagues from Chile, Italy and Cuba, have identified tomatoes whose leaves are rich in a "precursor" of vitamin D3. Scientists have edited the plant's genome so that the substance accumulates in ripe fruits. The new species is rich in a vitamin whose deficiency leads to serious health problems. According to scientists, about a billion people in the world suffer from a lack of vitamin D, and this number is growing. The main reason, according to experts, is inadequate nutrition. Our bodies can synthesize vitamin D from 7-dehydrocholesterol (7-DHC), also known as provitamin D3. This happens under the influence of ultraviolet radiation on the skin. However, food remains the main safe source. But fish and dairy products are expensive and not available to everyone, and there is little D3 in plants. Provitamin D3 (7-DHC) is produced by some plants, in particular tomatoes, but this occurs during the synthesis of cholesterol, mainly in leaves and in small ... >>

Teenagers don't listen to their parents 23.05.2022

Many, many parents are faced with the fact that their child, only yesterday still obedient, suddenly turns into a difficult teenager who is clearly not interested in what dad and mom say, who does everything differently than he is told, who behaves as as if he does not hear the elders at all. Employees of Stanford University found out that everything is true: teenagers do not hear their elders in the truest sense of the word. True, it’s not that they don’t hear - it’s just that the parental voice ceases to be the main one among the voices of other people. What does cease to be the main mean? In past work, scientists have explored how the child's brain perceives the mother's voice. It turned out that the voice of the mother includes a number of zones in the child's brain, ranging from purely auditory to those responsible for self-awareness and facial analysis. Moreover, the mother's voice activates all these zones more strongly than the voice of an unfamiliar woman. These experiments were done with children from 7 to 12 years old; children were already invited for new experiments about ... >>

With the rapid development of metallurgy, galvanization, dye and battery production, mining and other industries, the problem of cadmium pollution is becoming more and more serious. The study was led by Wu Zhengyan from the Institute of Intelligent Mechanisms of the Chinese Academy of Sciences and Cai Dongqing from Donghua University. As a result, a new method was found for treating water and soil contaminated with cadmium, as well as a new method for disposing of liquid waste from the tobacco industry and iron waste, which can pollute the environment. In the course of scientific work, which lasted about a year, it was calculated that 12 tons of iron-based carbon microspheres obtained from 10 tons of iron waste and 20 thousand liters of liquid tobacco from ... >>

Restored photosensitivity of cells after the death of a donor 21.05.2022

Scientists at the John A. Moran Eye Center at the University of Utah have brought light-sensitive neuronal cells back to life in the eyes of organ donors and reconnected them. The billions of neurons in the central nervous system transmit sensory information in the form of electrical signals. In the eyes, light is perceived by specialized neurons - photoreceptors. In this work, the researchers used retinas from organ donors hours after death as a model of the central nervous system to study how neurons die and find new ways to revive them. "We were able to wake up photoreceptor cells in the macula, which is the part of the retina responsible for our central vision and our ability to see fine details and colors," explains John A. Moran Eye Center researcher Fatima Abbas, Ph.D., lead author of the study. - "In the eyes obtained five hours after the death of an organ donor, these cells reacted to bright light, colored ... >>

The robot will determine the salinity of the dish 21.05.2022

Researchers at the University of Cambridge decided to train their robot chef in tasting skills: now he can taste the dish and see if it is salty enough. In this way, a mechanical chef will be able to prepare dishes "to the individual taste" and at the same time pay attention to more details during cooking. In order for the robot to determine the taste of the dish, a special probe was attached to it, which acted as a salinity sensor. During the experiment, the robot, which was trained to make an omelet, tried the dish nine times, tasting it. He also added tomatoes to the omelet. Robots can rate dishes for saltiness much better than existing tasting methods, the study found. Now the researchers hope that very soon robots will be able to compete with real chefs in the best restaurants. However, scientists also pursue socially significant goals: such robots will be able to help pensioners and people who do not have time. ... >>

Antibiotics interfere with childhood vaccinations 20.05.2022

The level of vaccine antibodies in young children is lower if they were given antibiotics at the time of vaccination. Children receive (if they receive) their first vaccinations in their first six months of life, but if the child is not lucky and has caught some kind of infection, then antibiotics are also waiting for him. Rochester Central Hospital Research Institute and Rochester Institute of Technology researchers have been comparing vaccine responses in children aged six months to one year for ten years: some of them received antibiotics, some did not. There were four types of vaccines: combined against diphtheria, tetanus and whooping cough, against poliomyelitis, against pneumococci and against Haemophilus influenzae. It turned out that antibiotics reduce the effectiveness of vaccines: with them, the level of corresponding antibodies that developed immunity against vaccine pathogens decreased, and the more antibiotics a child was given, the less antibodies he had. In the first vaccination, the level of antibodies fell by an average of 5-11% for each a ... >>

Self-charging battery 20.05.2022

Scientists believe that half of the solar energy that hits the Earth is used to evaporate water from its surface. The Australian company Strategic Elements has set itself the goal of using at least some of this energy in the form of electricity. Together with local scientists, the company has developed a battery that charges itself solely due to the difference in humidity on its electrodes: the higher the humidity, the faster the charge. A team of scientists from UNSW and CSIRO has developed a battery that operates on a humidity gradient. The development is based on graphene oxide, which Energy Ink also talks about. Graphene oxide in the battery plays the role of a carrier of ions and a medium for their appearance in the process of absorbing moisture from the air. The electrodes are a layer of fluorine-doped tin oxide (FTO) and silver. In the dry "functional layer" of graphene oxide, the protons are immobilized (fixed) and motionless. When a moisture difference occurs, one side begins to absorb ... >>

Maple seeds will double the flight time of drones 19.05.2022

The heavier the drone, the longer it can stay in the air. Against light and ultra-light drones, physics plays against which small-capacity batteries cannot cope. But nature has answers for everything, including the problem of extending the flight time of ultralight aircraft, for which it is enough to study a maple seed. Maple seed - lionfish - can soar in the air for a long time. The seed element in the form of a wing, when rotating around the center of gravity, creates lift, allowing the wind to carry the planting material far. Scientists have repeatedly paid attention to lionfish, and in a new study, researchers from the City University of Hong Kong have indicated their portion of interest in the structure of the lionfish. The proposed design of a lightweight drone weighing only 35 grams looks like a twin lionfish with large wings made of polyamide film on carbon fiber rails. The original decision was to place small electric motors near the ends of the parallel wings. ... >>

Silent ion powered drone 18.05.2022

Undefined Technologies from Florida (USA) has introduced the next generation of its "silent" commercial UAV Ventus, which uses an ion engine instead of propellers. Undefined Technologies started developing the prototype a year and a half ago. It is based on the patented Air Tantrum technology, the details of which are not disclosed. However, the company indicates that it is thanks to her that the device will be very quiet. The concept was first presented in 2021, since then it has been significantly improved. Ion thrusters are used in rocket science. This type of electric motor is remarkable in that it does not require a lot of fuel and lasts more than 3 years, which is a high indicator. It works according to the following principle: ionized gas is accelerated to high speeds in an electric field, which provides jet thrust. Scientists from the Massachusetts Institute of Technology experimented with ion engines. They developed an aircraft with this type of engine, one ... >>

Bats pretend to be wasps 17.05.2022

Bats prey on insects, but who preys on bats? Birds. Naturally, not tits with sparrows, but birds of prey, and nocturnal ones, that is, owls - let's not forget that many bats are active at dusk or even at night. It is difficult to dodge an owl, but some bats have found a way: they scare away owls by buzzing like bees or wasps. Employees of the University of Naples named after Frederick II, studying the big bats, noticed once that the caught bats buzz like a wasp. Moreover, these were not the usual call signs of bats: they use other signals to communicate with each other and for hunting. The researchers caught a few more bats, recorded their buzzing and compared it to that of two species of bees and two species of wasps that are common in European forests. The sounds of bats turned out to be in many ways different from the sounds of insects - but this is if they are compared using special algorithms that take into account all acoustic parameters. However, even owls, with and ... >>

Plants grown in lunar soil 15.05.2022

Scientists from the University of Florida (USA) have shown that plants can successfully grow in the lunar "soil". The scientists also figured out how plants react biologically to lunar regolith, a soil that is radically different from Earth's. The researchers had 12 grams - just a few teaspoons - of lunar soil for this experiment. The samples provided by NASA were collected during the Apollo missions to the moon. To grow their tiny "moon garden," the researchers used thimble-sized holes in plastic cups in which cells are normally cultured. After filling each "pot" with about a gram of lunar soil, the scientists moistened it with a nutrient solution and added a few seeds of Tal's clover (Arabidopsis). Since the genetic year of this plant is known, scientists could better understand how the lunar soil affects plants - right down to the level of gene expression. For comparison, the researchers also planted the rhubarb in a substance that mimics ... >>

Cells increase in volume when tissues are bent 14.05.2022

Scientists at the University of Geneva (UNIGE) have found that when tissue bends, the volume of its constituent cells increases rather than decreases. This discovery opens up new possibilities for growing organs in vitro. They will allow to some extent to reduce the number of experiments on animals. Morphogenesis is responsible for how cells are distributed in space to give shape and structure to our organs. This process is triggered during embryonic development and explains how, for example, the folds of our intestines or the alveoli of our lungs are formed. In other words, its mechanisms underlie our development and the development of all living beings. In the new study, the UNIGE team looked at how the cells that make up tissue react and adapt when the tissue is flexed. By folding up a cell monolayer in vitro, which is a compact, flat "sheet" of cells stacked next to each other, scientists made a paradoxical discovery. They found that the volume of cells dispersed ... >>

Algae electric battery 14.05.2022

Researchers from the University of Cambridge (UK) have created a reliable and renewable biological photovoltaic cell based on cyanobacteria. With it, they were able to continuously charge the microprocessor for a year. For this, only light and water were needed. The system - about the size of an AA battery - is made from common, inexpensive, and largely recyclable materials. It includes the algae Synechocystis, which naturally harvest solar energy through photosynthesis. The weak electrical current that is generated in the process then interacts with the aluminum electrode and is used to power the microprocessor. The new photovoltaic device does not discharge in the same way as, for example, a lithium-ion battery, because it constantly uses light as a source of energy. And, despite the fact that photosynthesis requires light, the device can continue to generate energy even in the dark. ... >>

Everest will build the highest weather station 13.05.2022

Chinese scientists have focused their efforts on the creation of a meteorological monitoring station at an altitude of 8,8 km on Mount Everest (Chomolungma), the highest peak in the world, on the border of China and Nepal. If the station is successfully installed, it will replace a similar facility at an altitude of 8,43 thousand meters, installed by British and American scientists on the south side of the mountain in 2019. The new station will be the world's tallest of its kind, according to a statement from the Tibetan Plateau Research Institute (ITP) of the Chinese Academy of Sciences. "Equipment weighing about 50 kg will be dismantled and distributed to climbers, each of whom will carry no more than 7 kg up the mountain for further installation," said ITP researcher Zhao Huabiao. At present, the engineers responsible for building the station are still waiting for the perfect weather for mountain climbing. Including the highest one, eight meteorological stations with a height gradient will be established on Mount Everest, which is one of the main tasks of the ... >>

In recent years, the development of virtual reality, artificial intelligence algorithms and big data has generated incredible amounts of data. And traditional memory types are limited in scaling. The situation calls for an entirely new technology such as CXL. ... >>

Vampire star discovered 12.05.2022

After studying mysterious flashes of light emanating from one of the Milky Way's systems, researchers have discovered what they suspect is the elusive Black Widow-type star. Scientists have found evidence of the existence of a vampire star in our galaxy. Also known as the Black Widow. This object is a pulsar that spins very fast and sucks energy from a companion star. The object was identified in the system under the designation ZTF J1406+1222. The pulsar found there is located approximately 3000-4000 light years from our planet. The Black Widow and her victim revolve around each other every 62 minutes. In order to detect this system, scientists from the Massachusetts Institute of Technology had to use the latest technology. They had to look for visible light that comes from the victim star. It is assumed that the "Black Widow" will eventually completely absorb its neighbor. ... >>

Motorola rollable smartphone 11.05.2022

Motorola has begun designing an ambitious device in an original form factor. A distinctive feature of the novelty will be a flexible display, which is pulled out of a kind of "roll" hidden in the body of a familiar monoblock - but not sideways, but upwards. Unlike the previously shown OPPO X 2021 or LG Rollable concept phones, the novelty, codenamed Felix, according to insiders, will be able to stretch not in width, but in height. This will combine such characteristics of the device as a large screen area and compact dimensions. It is reported that the rolled design will allow hiding up to a third of the matrix in the case, due to which, when folded, the device will be practically indistinguishable from conventional models. It is expected that when used in landscape mode, the gadget will be able to use the split display feature introduced in Android 12. The company is already testing the new technology on a modified Edge 30 Pro. Possible date of the announcement of the conceptual smartphone ... >>

Enzyme to break down plastic per day 11.05.2022

Scientists at the University of Texas at Austin have used artificial intelligence to develop a synthetic enzyme that breaks down plastic waste in 24 hours. The researchers studied the natural structure of the PETase enzyme and trained the model to generate mutations that work quickly at low temperatures. "When considering approaches for waste disposal, you need an enzyme that can work in nature at ambient temperatures," said study co-author Hal Alper. The algorithm ended up with an element called FAST-PETase, which can break down plastic in 24 hours at temperatures ranging from 30 to 50 degrees Celsius. According to scientists, the production and use of the enzyme can be brought to an industrial level, providing an affordable way to process plastic waste. They added that the biological approach uses less energy and is more environmentally friendly than current large-scale polyethylene recycling methods. "This job is really dem ... >>

Space hotel with artificial gravity 10.05.2022

The American company Orbital Assembly announced that it plans to build a space station in orbit by 2025, which will be both a hotel for tourists and a place for scientific research. The company wants to build another commercial station later. According to the project, 28 space tourists will be able to stay at the new orbital station at the same time, who will live in 5 modules. Those, in turn, will be placed around the ring, which, by its rotation, will create artificial gravity. The Pioneer station will be the first of two commercial stations planned to be built in orbit. The second station is to be built later and will be able to accommodate 400 space tourists. "Our station is a safe and reliable modular design that will begin to generate revenue earlier than the stations of our competitors contracted by NASA," said Rhonda Stevenson, executive director of Orbital Assembly.

Secrets of home walking cats 09.05.2022

The cat is one of the most common pets on the planet. Today in the world there are about 600 million domestic individuals. In Norway alone, there are about 5,4 such pets per 770 million people. Pets are often let out by owners, and scientists at the Norwegian University of Life Sciences asked questions: where do these domestic cats go, what do they do, and how long does it take to return home? Domestic cats are rarely seen as members of the large carnivore population they actually belong to. Knowledge of individual behavior is quite extensive, but so far very little is known about how the local free-range cat population occupies a territory. To fill this gap, the researchers provided GPS trackers to almost all domestic cats that make up the population of a small town in eastern Norway. Pet owners lived within one square kilometer, so tracking walks 1 ... >>

The largest silicon carbide power electronics factory 08.05.2022

The American company Wolfspeed, a subsidiary of CREE, has inaugurated the world's largest silicon carbide power semiconductor plant in New York State. Strength elements based on silicon carbide (SiC) compare favorably with similar silicon components. In particular, elements based on SiC have higher electrical strength, lower losses, higher speed and operating temperature, and higher radiation resistance. This makes silicon carbide power cells attractive for power supplies, inverters, and other power subsystems in devices from consumer electronics to spacecraft onboard equipment. For example, Lucid Air electric vehicle inverters use Wolfspeed silicon carbide XM3 power modules. With low switching losses, low resistance, and high power density, XM3 Power Modules help improve motor efficiency and power density. ... >>

Grasshopper robot 08.05.2022

Engineers at the University of California at Santa Barbara have designed an artificial grasshopper that can jump over 30 meters. At the same time, its design itself reaches only 30 centimeters in height. The whole construction work acts like a spring. It consists of rubber bands and carbon fiber slats. When the actuator (Light Rotating Motor) rotates, it winds the string that compresses the spring. So the drive pulls on the rubber bands and compresses the carbon fiber, bending each bar into a curved shape, similar to a shooting bow. After that, the latch is released and the robot is thrown into the atmosphere. This mechanism is similar to those used by animals. For example, the leg muscle of a grasshopper also serves as an actuator: when it contracts, it bends the spring-like part of the knee joint, creating the tension necessary for jumping. The robot can jump over buildings and move efficiently in environments where the movement of wheeled, walking and ... >>

Ultra-clean diamond wafers with up to 25 EB of data 07.05.2022

One of the types of diamond point defects makes it possible to use it as a quantum bit for organizing calculations or storing data. This can be hindered by the imperfection of the technology for growing ultra-pure diamond disks, which has become a challenge for scientists. The Japanese accepted the challenge and were able to find an interesting solution to the problem. If at any site of the diamond crystal lattice one of the carbon atoms is replaced (bonded) by a nitrogen atom, then such a violation of the diamond crystal structure will be called a nitrogen-substituted vacancy in diamond or an NV center. Such a point defect has quantum properties that can be easily controlled by light, magnetic fields, or other influences even at room temperature. In particular, the NV center can be used to record and store data. A feature of diamond structures with NV centers is that there should not be too much nitrogen. Therefore, for the practical use of diamond data carriers, it is necessary either to produce very large ... >>

CAMM is the new standard for ultrabook RAM 07.05.2022

Dell has developed an original alternative to the SO-DIMM standard, which has not changed for many years, and is well known to owners of laptops and mini PCs. The new form factor is designed to reduce the thickness of modern laptops and the number of connectors on their motherboards without sacrificing performance. CAMM modules (Compression Attached Memory Module) differ from the usual solutions primarily in size. Due to the use of a flat contact pad, they are 57% thinner, which allows them to be installed in compact ultrabooks, replacing two traditional ones with one universal bar. The memory capacity of new products (DDR5 standard, effective frequency up to 4800 MHz) can range from 16 to 128 GB, while older models will be dual-rank. Each CAMM also includes its own Programmable Memory Chip (PMIC). The company has already stated that the new standard will not be closed - other laptop manufacturers will be able to use it. Branded connector, if necessary, it will be possible ... >>

1,6 nm gears for molecular machines and nanorobots 06.05.2022

Devices are getting smaller and require tinier parts. Researchers at the University of Erlangen-Nuremberg (FAU) in Germany have made the world's smallest working gear. This chemical gear is needed for the operation of molecular machines and nanorobots. It will help create electronic components, transport drugs inside the human body, manipulate individual cells or molecules. To this end, scientists have already developed nanoscale versions of many parts, such as engines, pistons, pumps and propellers. The FAU scientists have added the cogwheel to this list. It consists of two interconnected components, including a trypticene molecule with a propeller-like structure and a flat section of a thioindigo molecule perpendicular to it (gold plate). Together they work like a gearbox. The pair has a gear ratio of 2:3. So when the plate rotates 180 degrees, the propeller only rotates 120 degrees. All device contain ... >>

Economic technology of carbon capture by algae 06.05.2022

London-based startup Brilliant Planet has developed algae-based carbon capture and storage technology that will cost between $50 and $100 per tonne of carbon. The technology based on algae blooms has the prospect of scaling up to billions of tons per year with negligible energy requirements. The cultivation of algae will contribute to the deacidification of sea water, which will contribute to a more efficient absorption of carbon by the ocean. The algae will be grown in large, open, low-density ponds filled with seawater. Algae are inherently more efficient biological carbon sequestration machines than trees or other plants because their entire surface is capable of photosynthesis and they do not waste resources creating trunks, roots or branches. They also grow and reproduce very quickly under the right conditions. The company uses flat deserts along the coasts and local strains of algae well adapted to local conditions. ... >>

Electronic skin that senses touch 05.05.2022

Scientists from Chemnitz and Dresden (Germany) have developed an electronic skin with artificial hairs. The new system mimics the sensitivity of human skin, and can be used to replace damaged skin or create a coating for android robots. Hairs on the skin help us recognize and anticipate the direction of touch and tactile sensations. But artificial leather is deprived of such an opportunity. A team of researchers have created extremely sensitive 3D magnetic field sensors that have been used for the e-skin system. Their approach has allowed the creation of compactly arranged sensor elements that can be mass-produced. Previously, such elements could not be created using modern methods of manufacturing microelectronics. The core of the system is an anisotropic magnetoresistance (AMR) sensor. It is designed to detect magnetic fields, for example, in vehicle speed sensors. To compactly place the sensors, the researchers used " ... >>

Quantum microscope sees tiny changes in atoms 05.05.2022

Physicists at the University of California, Irvine have demonstrated the use of a hydrogen molecule as a quantum sensor in a scanning tunneling microscope (STM) equipped with a terahertz laser that can measure the chemical properties of materials with unprecedented resolution. This new technique could also be applied to the analysis of XNUMXD materials that could potentially play a role in advanced energy systems, electronics and quantum computers. Researchers from the Department of Physics and Astronomy and the Department of Chemistry at UCI described how they placed two bonded hydrogen atoms between an STM silver tip and a sample consisting of a flat copper surface with small islands of copper nitride. Using laser pulses lasting trillionths of a second, scientists were able to excite a hydrogen molecule and detect changes in its quantum states at cryogenic temperatures and in the ultra-high vacuum of the device, creating images of the image ... >>

MUCCC (Multifunctional Concert and Congress Center) will be built next to Munich Airport, close to the local center for technological development and innovation. The height of the building will be approximately 34 m - it will be a classic round arena, supported from the outside by a cellular exoskeleton. One of the main advantages of the project will be its environmental safety - both the use of secondary raw materials and complete energy autonomy are envisaged. The arena will be climate neutral thanks to the technologies used in construction and energy supply. The use of solar cells is provided both on the roof and in the surroundings. ... >>

Simple technology for the production of speakers in rolls 04.05.2022

Scientists from the Massachusetts Institute of Technology have developed a simple technology for the production of audio speakers. They can be produced in rolls and the thickness is no more than ordinary paper wallpaper. Any surface can be turned into a source of high-quality sound. The researchers replaced a speaker with a single large cone with a continuous field of thousands of micron-sized cones (speakers). The height of each diffuser (dome) is 15 microns. It is about six times thinner than a human hair. During the sound, the cone stroke does not exceed half a micron. But all together, the microspeakers create a sound of considerable volume so that they can be used as conventional audio speakers. "It's a wonderful feeling to take what looks like a thin piece of paper, attach two clips to it, plug it into your computer's headphone port and start hearing sounds coming out of it. You can use it anywhere. It only needs a small amount of electricity to work." , - rassk ... >>

A new cell type in the human body 03.05.2022

Researchers at the University of Pennsylvania's Perelman School of Medicine, which specializes in respiratory systems, have discovered an entirely new type of cell lurking in the thin, branching passageways of the human lung. Newly discovered cells play a vital role in maintaining the normal functioning of the respiratory system. Scientists suggest that they may inspire the creation of new treatments to prevent the effects of diseases associated with smoking. In particular, chronic obstructive pulmonary disease - COPD. Cells known as respiratory secretory cells (RAS) are found in tiny branching passages known as bronchioles that end in alveoli, tiny air sacs that exchange oxygen and carbon dioxide with the bloodstream. The new RAS cells are like stem cells - "blank canvas" cells that can differentiate into any other cell type in the body - and are able to repair damaged cells. ... >>

Collision of protons is simulated 02.05.2022

Scientists from the National Laboratory. The Berkeleys used the IBM Q quantum computer to do part of the calculation for the collision of two protons. To do this, they split the effective field theory into several parts and developed an algorithm that allows certain calculations to be performed on a quantum computer. Berkeley Lab is engaged in the study of particle physics by observing the collision of high-energy particles in the laboratory, for example, using the Large Hadron Collider in Switzerland. Scientists compare theoretical calculations of these collisions with real-life experimental results. “One of the main challenges of this kind of calculation is that we want to describe a wide range of energies,” said Benjamin Nachman, one of the researchers. “We want to describe processes from the highest energy to the lowest energy by analyzing the corresponding particles that fall into our detector.” . Using exclusively a quantum computer for p ... >>

Bacteria found that converts methane into electricity 02.05.2022

Microbiologists at the University of Nijmegen in the Netherlands have found that the bacterium Candidatus Methanoperedens is able to convert methane into usable energy. With the help of it, scientists managed to turn 31% of harmful gas into electricity. The bacterium Candidatus Methanoperedens belongs to anaerobic methanotrophic archaea - microbes that can survive in the most extreme conditions, even where there is no oxygen. These bacteria are found in fresh water polluted with nitrogen, such as ditches and lakes. They need nitrate to break down methane. Researchers have created something like a battery with two "terminals": one of them is biological, and the other is chemical. Candidatus Methanoperedens was grown on one of the electrodes, where bacteria began to donate electrons that arose due to the splitting of methane. So it was possible to achieve the conversion of 31% of the produced methane into electricity. So far, the efficiency of the method is not high, but it can be increased in the course of further experiments. "It can be very helpful for ... >>

Polysexual mushroom 01.05.2022

We are used to the fact that living beings have only two sexes. It happens that both sexes are combined in one individual, then this is called hermaphroditism. It happens that there are no sexes - such organisms reproduce asexually. But it also happens that there can be three or more sexes - much, much more. As, for example, in mushrooms from the genus Trihaptum, in which researchers from the University of Oslo and their colleagues from Spain and the USA counted 17550 sexes. Mushrooms themselves are not so exotic - they are related to tinder fungi and their range is very wide; one of the trihaptums grows on birch trees and is found throughout the country. How come they have so many genders and what does that even mean? The meaning of sexual reproduction, in addition to getting an individual of a new generation, is in mixing genetic material. The germ cells of one sex merge with the germ cells of the other sex, and an organism is obtained with a new combination of genes. The more diverse the combinations of different individuals in a population, the more likely it is to survive. ... >>

bacterium noise 28.04.2022

The team of scientist Farbod Alijani at the Delft University of Technology captured the noise that bacteria make while initially investigating the underlying physical mechanics of graphene. Graphene is a form of carbon made up of a single layer of atoms, also known as the wonder material. It is very durable, with good electrical and mechanical properties, and is also extremely sensitive to external forces. This animation shows how a graphene drum can make bacteria sounds. The sound stops when the bacteria is killed by the antibiotic. When a single bacterium sticks to the surface of a graphene drum, it generates random vibrations with an amplitude of only a few nanometers that could be detected. Scientists were able to hear the sound of a single bacterium! To understand how tiny these blows of the flagellum on graphene are, it is worth saying that they are at least 10 billion times smaller than the blow of a boxer when he reaches a punching bag. However, these nanosized bits ... >>

In Europe, USB Type-C has become the standard smartphone charging port. 28.04.2022

The EU Committee for Internal Market Regulation and Consumer Protection decided by 43 votes in favor to approve USB Type-C as a single charging connector throughout the EU. Votes "against" were given only by two members of the committee, informs TechPowerUp. The specified charging standard is planned to be applied to devices from among "small and medium electronic gadgets" (including mobile phones, tablet PCs, digital cameras, headsets and headphones, portable game consoles and portable speakers). An exception is provided for devices that are not suitable for USB-C installation due to their too compact size (examples are smart watches, medical and sports trackers, etc.) The directive has yet to be approved by the EU Parliament May of this year). If the Committee's decision is approved, manufacturers of "smart" devices will be given a transitional period until the first quarter of 2024. In addition to all of the above, MPs ... >>

Found a reliable way to transfer energy without wires 27.04.2022

A team of scientists from the US Naval Research Laboratory has tested a new technology for wireless power transmission. Using microwave radiation, physicists managed to transmit electricity with a power of 1,6 kilowatts over a distance of 1 kilometer at the US Army research site in Blossom Point (Maryland). The Laboratory emphasizes that this is the most successful and reliable demonstration of wireless power transmission in the last 50 years. Energy beams are transmitted between two points within the Safe and Continuous Power bEaming - Microwave (SCOPE-M) system. Special equipment converts electricity into microwaves, which are then focused by a narrow beam on a receiver with the so-called rectennas (rectifying antenna - rectifying antenna) - this is a special type of receiving antenna with high-frequency diodes. When microwaves hit the rectenna, they are converted into direct current. For 12 months, American scientists tried using SCOPE-M to transmit email ... >>

Breaking the record for the length of a quantum communication line 25.04.2022

Chinese scientists have set a new world record for the length of a quantum secure communication line. It was 102,2 km, beating the previous figure of 18 km. True, in such a network, the transmission speed was very low - 0,54 bits per second, but still sufficient to encrypt text messages and phone calls at a distance of 30 km. The results of the work may eventually lead to the creation of a tamper-proof communication, since any attempt to listen to the quantum line can be instantly detected. The same research team set the previous record. Now she has improved her network. The improvements allowed them to lengthen the line from 28,3 km to a record 102,2 km. The experiment shows that direct quantum-safe communication between cities via optical fiber is possible using modern technologies. ... >>

New way to detect tsunami 25.04.2022

Japanese scientists have proposed a new approach to tsunami detection, which is to monitor muons. Muons are high-energy elementary particles that are created by cosmic rays arriving from outer space. They are everywhere in the atmosphere and can pass harmlessly through almost anything. However, they can be very slightly displaced in their path by large natural forces, including tsunamis. In order to detect the movements of muons, an incredibly sensitive instrument is required - TS-HKMSSD. He first detected tsunami waves through muon ripples. "The Tokyo Bay Hyperkilometer Underwater Depth Detector is the world's first underwater muon observatory to detect various muon activity during a tsunami," said geophysicist Hiroyuki Tanaka of the University of Tokyo in Japan. This variation is consistent with ocean waves that have been measured by other methods. Consolidation of readings means that muographic data can be used ... >>

Molecular pathway found for critical cases of COVID-19 24.04.2022

An international team led by Chinese researchers has identified a molecular pathway that exacerbates the severity of critical COVID-19 cases, providing clues for a potential treatment for such cases. A new study has shown that the fusion of coronavirus-infected lung cells can exacerbate inflammatory responses, thereby triggering immune signaling cascades in the lungs, which are a major factor in lung damage in patients with severe disease. Scientists from the Chinese Academy of Medical Sciences and the Peking Union Medical College and their collaborators analyzed post-mortem patient samples. They found a correlation between critical cases of COVID-19 and a fusion of lung epithelial cells called pneumocytes, which has also been seen in macaques and cultured cells infected with the virus. They then examined human embryonic kidney cells that either expressed the SARS-CoV-2 spike protein, causing ... >>

Printing 3D glass structures 23.04.2022

Chemically and thermally resistant glass is much preferred in industry, medicine and science over plastic. And if people have learned to cope well with the printing of plastic 3D models, then glass 3D printing could help develop many promising areas. Now it's possible. American and German scientists have learned how to quickly print micron-scale 3D glass models. The proposed technology is based on the Glassomer material invented by scientists at the University of Freiburg and a 3D printing method called "Computer Axial Lithography (CAL)" invented at the University of California at Berkeley. The CAL method was introduced about four years ago. liquid polymer resin, a 2D model is projected at different angles.Where the light intensity reaches the threshold value, the resin quickly hardens.Then it is enough to wash the model in a solvent to remove the liquid composition and the model is ready, which takes count ... >>

Charging implants with ultrasound 23.04.2022

Various kinds of electronics have long been implanted in the human body. A typical example is a pacemaker. But when its battery runs out, the implant needs to be surgically replaced. Korean scientists have found a way to solve this problem using remote ultrasonic charging. Although there are many wireless charging technologies in the world of electronics, the most current ones are not suitable for medical applications. So, electromagnetic induction allows you to charge the batteries of smartphones located at a distance of up to 1,5 cm from a special panel, and quite a lot of heat is released in the process, which is unacceptable when the battery is hidden in the tissues of a living organism. Another method is charging using magnetic resonance, but the equipment in this case can be affected by wireless signal sources such as Bluetooth or Wi-Fi. With these and other limitations in mind, a team of scientists from the Korea Institute of Science and Technology (KIST) has developed an implantable generator that ... >>

Chopsticks that enhance the salty taste 22.04.2022

A group of Japanese scientists led by Professor Meiji Homei Miyashita has developed chopsticks that make food saltier. This will help those who need to reduce the amount of sodium in their diet. The chopsticks, co-developed by Miyashita and beverage maker Kirin Holdings Co., enhance flavor with electrical stimulation and a mini computer that looks like a bracelet. The gadget uses a weak electric current to transfer sodium ions from food through the chopsticks straight into the mouth, which gives a sensation of saltiness. As a result, the taste of salty is enhanced by 1,5 times. Flavor-enhancing chopsticks may be of particular importance in Japan, where the traditional diet is high in salty foods. The average Japanese adult consumes about 10 grams of salt per day, twice the amount recommended by the World Health Organization. Excess sodium intake is associated with an increase in cases of high blood pressure, strokes and other diseases. ... >>

Optical fiber that works like the human nervous system 20.04.2022

Scientists from Singapore's Center for Disruptive Photonic Technology and the UK's Optoelectronics Research Center have created a working optical model of a neuron. To do this, they took advantage of the special properties of an amorphous alloy based on chalcogenides. In fact, a new type of optical fiber was synthesized, capable of changing transparency. This makes it possible to provide conditions for the propagation of optical signals similar to those that exist in the human brain. Using this property, the researchers achieved functionality that mimics the mechanism of signal propagation in axons and synapses, thereby proving that optical analogs of neurons can demonstrate functionality similar to the human brain. The optical fiber for the experiment was made of amorphous glass, which is an alloy of gallium sulfide and lanthanum oxide. To emulate the functions of a chemical synapse, the fiber is alternately irradiated from the side with light of different wavelengths, causing the so-called ... >>

Solar panels working at night 19.04.2022

Scientists at Stanford University have developed solar panels that can generate electricity at night when the sun has already set. To do this, they assembled a structure from conventional solar panels and a thermoelectric generator. Given that any matter with a temperature above absolute zero radiates heat into the atmosphere, the proposed design allows it to be captured - from the solar panels themselves. By "capturing" the temperature difference between the ambient air and the panels, the thermoelectric generator receives the necessary electricity. Stanford University engineers managed to collect up to 50 milliwatts per square meter of solar panels placed on the roof of the university buildings. Experts believe that they will be able to double the figure with a theoretical limit of 1-2 watts per square meter. This is not much, but for some tasks it is more than enough. ... >>

Reusable pollen paper 18.04.2022

Despite the ubiquity of computers and electronic document management, humanity still consumes colossal amounts of paper, which requires wood to make. Therefore, many engineers and scientists are looking for technologies to create alternative materials, including those with the ability to "rewrite". A new such "paper" was recently presented by the developers of the Nanyang Technological University in Singapore. The production of the innovative material, unlike conventional paper, is almost environmentally friendly: it is suitable for standard full-color printing, and it can be reused up to eight times. Traditionally, paper is made from cellulose, which is obtained from wood and plant fibers. Up to 40 percent of all wood traded on world markets is used for these purposes, as a result, paper production makes a significant contribution to deforestation. In addition, the process, including bleaching, requires high temperatures and the use of palate. ... >>

Hardware Optimization Reduces 5G Power Consumption 18.04.2022

The deployment of 5G networks allows to improve the quality of service and data transfer speeds, responding to the growing demand for the volume of transmitted information. In terms of energy consumption per unit of traffic, 5G is 90% more efficient than 4G, but in absolute terms, a sharp increase in power consumption is expected due to the implementation of Massive Multiple-Input, Multiple-Output (mMIMO) technologies and increased network density. According to analyst firm ABI Research, a 5G base station requires three times as much power to provide the same coverage as a 4G network. This is a new burden for network operators to cope with high energy costs and rising capital costs. "Hardware optimization" can correct the situation, which will lead to a significant reduction in power consumption. By optimization, analysts mean the release of a new generation of chipsets that will consume 30-70% less energy compared to their predecessors. "Sweat ... >>

ultrasound for diabetes 17.04.2022

An international team of scientists has figured out how short pulses of ultrasound, targeting specific clusters of nerves in the liver, can effectively lower insulin and blood glucose levels in diabetics. So far, the technique is being tested on humans and is quite complicated, but scientists are confident that they will be able to create portable devices for monitoring blood glucose and insulin levels. Unfortunately, there are currently very few drugs that actually lower insulin levels. Meanwhile, to maintain the health of patients with diabetes, it is necessary to be able to keep a balance in the level of glucose in the blood. The introduction of insulin reduces its concentration, but too low a glucose content can cause hypoglycemia and lead to death. Scientists have demonstrated for the first time a unique non-invasive ultrasound technique designed to stimulate specific sensory nerves in the liver. This technology is called peripheral focused ultrasound stimulation and allows very precise targeting. ... >>

The harm from e-cigarettes outweighs the benefits 15.04.2022

Scientists at the Australian National University have published a large review that analyzes the many scientific papers on electronic cigarettes and other vaping devices and their impact on health. Initially, there were about 19 thousand such studies. Then, when those that duplicate each other, those that do not meet the criteria for scientific publications, etc., were eliminated, 189 "e-cigarette" works remained, which, in general, is also not so small. The report outlines the range of ills that can result from vaping in one form or another, from poisoning and lung damage to addiction. Which is hardly surprising, since from these devices you inhale not just water vapor - you can find up to 243 different substances in nicotine-free e-cigarettes, of which thirty-eight are considered poisons. Although it should be noted here that not all vape liquids contain these substances, and it is unlikely that anyone died after the first puff, that is, dangerous substances are present there. ... >>

Skin rejuvenation for 30 years 14.04.2022

The researchers rejuvenated the skin cells of a 53-year-old woman, making them the same as those of a 23-year-old. Scientists from the University of Cambridge have achieved incredible results: they were able to make human skin cells look younger by as much as 30 years. Scientists believe that they can do the same with other tissues of the human body. Thus, it is possible to develop treatment for diseases that occur in older people. The origins of the method used by scientists in the new study date back to the creation of the cloned sheep Dolly in the 90s of the last century. Then scientists wanted to create the so-called human embryonic stem cells. They hoped that in this way they could be grown into certain tissues, such as muscles, cartilage, and nerve cells, to replace worn-out body parts. In 2006, Japanese scientists came up with a new method they called IPS. With it, scientists added chemicals to the cells of an adult organism ... >>

Planet 9 times larger than Jupiter discovered 13.04.2022

Scientists have observed a giant planet estimated to be about nine times the mass of Jupiter at a surprisingly early stage in its formation, described as "still in the womb," in a discovery that challenges current understanding of planetary formation. The researchers used the Subaru Telescope, located near the top of an inactive Hawaiian volcano, and the Hubble Space Telescope in orbit to discover and study the planet, a gas giant orbiting unusually far from its young parent star. Gas giants are planets, such as our solar system's largest planets Jupiter and Saturn, composed mostly of hydrogen and helium, with swirling gases surrounding a smaller solid core. "We think it's still in a very early stage of its 'birth'," said astrophysicist Thane Curry of the Subaru Telescope and NASA Ames Research Center. ... >>

Simulation of human behavior in a crowd 11.04.2022

Experiments conducted by researchers at Brown University have shown that each pedestrian in a crowd controls the direction and speed of their movement based on two visual variables. First, people try to move in such a way that their neighbors remain motionless in their perception. For this, the speed and direction of movement of those who walk nearby must be the same. Secondly, people prefer that the field of view does not change during movement. Such changes can occur when neighbors move closer or further away. Therefore, pedestrians in the crowd unconsciously try to fix the distance between themselves and their neighbors. The scientists also found that the participants in the experiment most of all reacted to the movements of their nearest neighbors. Changes in the behavior of those who walked at a distance did not have a strong effect. This is due to two effects, scientists say: the laws of optics and the principles of occlusion. The movements of a distant object seem less pronounced to us, and the pedestrians who are walking ... >>

Lubricated high load bearing composite 10.04.2022

Chinese scientists have developed a cartilage composite with mechanical strength. Natural articular cartilage exhibits exceptional tribological characteristics based on surface lubricated biomacromolecules and good mechanical stability. But inevitably they can also be damaged due to wear, disease and injury. Hydrogels are considered a potential alternative to natural cartilage due to their low surface friction and good biocompatibility. However, poor mechanical properties limit their application. Inspired by the optimal mechanical properties and stable surface lubrication mechanism of natural articular cartilage, researchers from the Lanzhou Institute of Chemical Physics of the Chinese Academy of Sciences have developed a lubricated bilayer composite exhibiting excellent mechanical stability and a unique stress dissipation mechanism. In the upper lubricating layer, the composite showed excellent t-reduction functions. ... >>

Mobile phones are not associated with brain tumors 09.04.2022

Scientists from the University of Oxford, together with colleagues from the International Agency for Research on Cancer, investigated the question of whether mobile phones are somehow associated with brain and eye tumors. It may seem strange to some that this is still being discussed somewhere. Nevertheless, oncology from a mobile phone remains an indestructible topic that is resurrected every time, as we are informed about the next step forward in telecommunications (now the emergence of 5G, the fifth generation of mobile communications, has turned out to be such a step forward). In 2011, the International Agency for Research on Cancer reported that cell phones can cause brain tumors, but most of the subsequent epidemiological studies did not confirm this, and mobile phones were recognized as safe. But if there is a "majority" of studies, then there is also a "minority" - with different results? Other results here are often related to the fact that for analysis they take the medical history of people who already have a cancer diagnosis. This ... >>

Chocolate in the morning helps women lose weight 09.04.2022

Chocolate is a product that has millions of fans around the world. The composition of sweets loved by many includes cocoa butter and grated cocoa, on which both health benefits and harms depend. It is difficult to count all the useful properties of chocolate. Among the main ones - it is able to increase the level of emotional state, reduce the risk of cardiovascular diseases and the amount of harmful free radicals in human blood. However, we must not forget that the uncontrolled eating of cocoa sweets will have the opposite effect on health. The result can be a rash, and in other cases, a favorite treat can cause tachycardia and increase blood pressure. Of course, the dosage is of great importance: if you consume chocolate in large portions (more than 100 g per day), then all the beneficial properties of sweets can disappear in an instant, causing great harm to the human body. According to findings from a study at Harvard Medical School and the Spanish University of Murcia, postmenopausal women ... >>

Green energy is on the rise 08.04.2022

From the report of the analytical company Ember, it follows that in 2021, 10% of electricity was generated worldwide from wind and solar energy, which became a new record. In total, 38% of the world's annual electricity was generated from clean energy sources, which also include nuclear energy, hydroelectric power plants and biofuels, which is even more than from burning coal. This gives hope for curbing a possible climate crisis. According to the Paris climate agreement, it is desirable to limit the increase in global average temperature in the world to 1,5 °C from pre-industrial levels. This will require maintaining an average 10-year increase in solar and wind power generation at 20% until at least 2030. In 2021, for example, the production of solar energy in the world increased by 23%, and wind - by 14%. Together, both renewable sources accounted for 10,3% of total global electricity generation, up 1% from 2020. When saved ... >>

Attitude to smells 07.04.2022

As it turned out, the perception of smells is universal for representatives of different countries, regions and cultures. While everyone has their favorite and least favorite scents, experts say it really comes down to simple chemistry. The structure of a single odor molecule dictates how people perceive and transmit it. In their new study, the scientists tried to determine which smell is the most pleasant for most people. The people who experienced smells during the experiment came from a wide variety of backgrounds, including indigenous groups who had little or no exposure to smells and food outside of their own culture. A total of 235 people were involved in the study. "Cultures around the world value different smells the same, no matter where they come from, but scent preferences are personal. We were trying to understand if people around the world have the same perception of smells and whether they like ... >>

Complete human genome presented 06.04.2022

Researchers have been able to decipher the missing links in the human genome and this makes it possible to find out where different mutations come from. 19 years ago, scientists announced that they had succeeded in deciphering the complete sequence of the human genome. But then about 8% of the information could not be deciphered. This happened because this part of the genome consists of repetitive DNA fragments that were difficult to connect with the rest. But now scientists from the National Human Genome Research Institute, which is part of the US National Institutes of Health, have solved this problem. "The fact that we have been able to completely decipher the complete sequence of the human genome is one of the greatest scientific achievements. It gives us complete information about the structure of our DNA. This will greatly expand the possibilities of research into genetic diseases in humans," says Eric Green, director of the National Genome Research Institute. person. The complete genome consists of 3,055 ... >>

microplastics in human blood 05.04.2022

Tiny bits of mostly invisible plastic have already been found almost everywhere on Earth, from the deepest oceans to the highest mountains, and in the air, soil and food chain. Now, scientists have added a final worrisome to that long list, as they have detected microplastics in human blood for the first time, warning that the ubiquitous particles can also enter organs. Dutch scientists conducted a study of blood samples from 22 anonymous healthy volunteers and found microplastics in almost 80% of them. Half of the blood samples contained traces of PET plastic, commonly used to make beverage bottles, while more than a third contained polystyrene, used to make disposable food containers and many other products. “This is the first time we have actually been able to detect and quantify such a microplastic in human blood. ... >>

The unmanned vehicle will calculate reckless drivers 04.04.2022

The University of Maryland has developed a new method for simulating the behavior of drivers on the road to train autonomous vehicles. A traffic simulation method developed by researchers at the University of Maryland is based on classifying the behavior of other road users. This model, which the authors called CMetric, analyzes the trajectories of other drivers and pedestrians. Based on the analysis and data obtained using computer vision, the algorithm can predict the possible actions of road users. “Using CMetric, our simulator can generate virtual motorists with different driving styles to pretrain self-driving cars,” says Angelos Mavrogiannis, one of the developers of the model. “Modeling heterogeneous driving behavior is a core element of our work. We use a deep reinforcement learning model, based on DQN (Deep Q-Network)." Developers note ... >>

Controlling technology with the power of thought 04.04.2022

Chinese scientists have developed a technology for controlling robotic equipment by recognizing brain activity. Control accuracy is impressive and accessible even without special training. In practice, the new technology will be implemented in a future Chinese orbital station, allowing taikonauts, for example, to control a huge robotic arm with just a thought. We are talking about simulation, not about the control of real mechanisms. However, there is only one step from simulation to real technology, and it will soon be taken. During the experiment, 35 volunteers had to mentally control a segmented robotic arm. Of this number, 11 participants immediately coped with the task. It is important to note that 27 test subjects had no experience in operating such devices at all, but after a little training, they were also able to control the mechanism with the highest accuracy. The average accuracy of operations has reached an unprecedented 99,07%. In all p ... >>

Another form of ice discovered 03.04.2022

Scientists now know at least 20 different forms of ice that have different crystal structures and form under different combinations of temperatures and pressures. The most common ice, the one used to cool drinks, is known as "ice I", and a number of well-known forms of ice end in "ice XIX". A group of scientists from the University of Nevada at Las Vegas (UNLV) has discovered another exotic form of ice that may exist in nature somewhere in the depths of the earth's mantle or on distant "water world" planets. As is often the case, a new form of ice was discovered by accident. UNLV scientists have been developing new methods for measuring the properties of water under ultra-high pressure conditions. A small amount of water was placed between the planes of a diamond anvil, the compression of which exposes the water to extreme pressures. This pressure forces the hydrogen and oxygen atoms to form various crystal structures, and then the resulting ice b ... >>

The Chinese company Oppo introduced a special Ice-Skin cooling case that cools the Find X5 Pro smartphone by 2-3 degrees. The body of the case received a special hydrogel layer developed by Wuhan University. It is noted that conventional hydrogels draw moisture from the air, and then release it by evaporation. To ensure long-term cooling, the case uses a modified Glacier Mat hydrogel that constantly absorbs moisture from the air, thereby cooling the smartphone. The company claims that the accessory will not greatly increase the weight and thickness of the Find X5 Pro smartphone compared to a regular protective case. Some users in China who pre-ordered the Oppo flagship will reportedly get a new case with it. ... >>

Automatic speed limit for electric scooters on sidewalks 02.04.2022

Australian electric scooter and bike sharing company Beam is preparing to test the Pedestrian Shield system, which automatically limits the speed of vehicles on sidewalks and in difficult environments. The technology will be tested in several Australian state capitals. Pedestrian Shield uses an AI system developed by Drover AI - the module is able to recognize streets, sidewalks and bike paths, including using nothing but an integrated camera, so no one needs to scrupulously mark the territory on GPS maps. Local city councils or fleet operators will be able to set speed limits at their discretion. In the case of Beam, there is a speed limit of up to 25 km/h on the roadway and bike paths, and up to 15 km/h on the sidewalk. At the same time, the system is capable of more - the Drover solution will be able to determine whether users park electric scooters in permitted areas. ... >>

Smart car system for forgetful parents 01.04.2022

Infalurt has introduced a smart system for rescuing children forgotten in the car. A capacitive sensor under the child seat will remind parents that a child is left in the cabin. The security system proposed by the Australian startup includes three components: a key fob, a control unit that is installed in the car interior, and a capacitive sensor. The key fob fixes the distance from the control unit. When the driver moves more than 10 meters away from the car, the system checks to see if someone is sitting in a child seat. If the child is left in the car, the control unit sends a signal in the ISM band. The key fob starts flashing and vibrating. Up to four capacity sensors can be connected to one control unit. This ensures the safety of all children, including those in a large family. The problem of children left in the car is especially relevant for countries with a hot climate. In Australia, several thousand children are found every year in cars at risk of dying from hyperthermia. Only in 202 ... >>

Good cholesterol protects against sepsis 01.04.2022

"Good cholesterol" refers to high-density lipoproteins, or HDL - large molecular complexes of lipids and proteins. The more of them, the less "bad cholesterol" in the blood, that is, low and very low density lipoproteins. "Bad cholesterol" increases the likelihood of atherosclerosis, "good" - reduces, in fact, that's why they are called that. Lipoproteins carry lipids from place to place, from tissue to tissue, and as such they influence various physiological processes - not only lipid metabolism, but also, for example, immunity. Researchers at the University of Kentucky and the University of Michigan noticed that patients with sepsis generally have lower "good cholesterol" levels than healthy people, and the lower the level, the worse the clinical prognosis. Sepsis, or blood poisoning, is an inflammatory response to a bacterial infection. Inflammation can be so severe that it will disable some organs and lead to death. Experiments with mice confirmed that the level of LP ... >>

Wireless powered maglev train 31.03.2022

A prototype maglev train powered by a unique wireless power supply has been tested in eastern China. Such vehicles, including monorails, have long used electromagnetic induction to generate power. However, Chinese scientists were able to surprise. Instead of the usual efficiency of 20-50% for such a method of energy transfer, Chinese technology provides an unprecedented efficiency of 92,4%. There is nothing like it anywhere in the world. Traditional maglev (maglev trains) use so-called linear motors. In this scheme, the monorail and train equipment are actually one electric motor. One moves relative to the other and this leads to the generation of electric current on board the maglev. The efficiency of such an engine can be at the level of 20% or a little more. In addition, such a system does not generate energy during a stop, which requires other sources to power the onboard equipment. The new Chinese technology is devoid of this shortcoming. ... >>

Self-learning electrical network 30.03.2022

Scientists from the University of Pennsylvania have discovered a new approach to machine learning. A conventional electrical circuit learned to recognize flowers by the size of their petals on its own. A team of scientists led by physicist Samuel Dillavu assembled a small electrical network by randomly connecting 16 resistors. Researchers set the voltage for certain input nodes and read the output nodes. By adjusting the resistors on its own, the network has learned to produce the desired data for a given set of input values. "The network has been set up to perform a lot of simple AI tasks," says Dillavu. "For example, it can distinguish between three types of iris flowers with over 95% accuracy based on four parameters: the length and width of the petals and sepals." For AI machine learning, as a rule, artificial neural networks are used. Such networks usually exist only in the computer's memory. The neural network consists of points or nodes, each of which can take on the value o ... >>

The fabric hears the sound 30.03.2022

Scientists from Singapore have created a smart fabric that works like a microphone, converting sound first into mechanical vibrations and then into electrical signals, similar to how human ears do. The nanomaterial is able not only to hear how the heart beats, but also, for example, to receive phone calls and SMS. The fiber is made of a piezoelectric material that generates an electrical signal when it is bent or mechanically deformed, allowing the tissue to convert sound vibrations into electrical signals. The fabric can pick up sounds in the decibel range and determine the exact direction they came from. “When wearing acoustic clothing, you can talk through it, answer the phone and communicate with other people,” says lead author Wei Yan, an assistant professor at Nanyang Technological University in Singapore. owners to control their heartbeat and breathing" ... >>

Genetic cause of early baldness 29.03.2022

Independent teams of scientists from the UK and Germany have discovered a new gene that contributes to the development of male pattern baldness. With a combination of both currently known genetic causes of baldness, the risk of this condition increases sevenfold. Scientists from the Universities of Bonn and Düsseldorf studied more than 500 regions of the human genome in 300 men with severe baldness. As a result, they were able to find a gene on chromosome 20 that promotes early hair loss. This gene can be passed down both maternally and paternally. Early hair loss in father and son may be due to the influence of this factor, says study leader Axel Hillmer (Axel Hillmer). Previously, the same group of researchers described another gene for baldness, located on the X chromosome and transmitted only through the maternal line. Carrying this gene, encoding the structure of the androgen receptor, is the most likely cause of early hair loss in a grandson and his grandfather. ... >>

Space rockets on wastewater 29.03.2022

Spanish scientists want to convert wastewater from astronauts on Mars into rocket fuel using solar energy. If humans are to survive on Mars, they will need to use all available resources, including astronaut sewage. Scientists have come up with a technology that uses sunlight to produce rocket fuel from this waste. The creation of a new technological process for the production of fuel on Mars is carried out by the Spanish technology company Tekniker. "We want to create the first reactor for the production of space fuel on Mars, using the planet's air, which is 95% carbon dioxide. The reactor will be powered by sunlight, and astronauts' wastewater will be used to produce rocket fuel," says specialist Borja Pozo from Tekniker. With the help of the new technology, it will also be possible to purify the water, and the astronauts will be able to reuse it. This project is reminiscent of the plot of the science fiction film "Marcia ... >>

robot shrimp 28.03.2022

Researchers at Brown University and the National Autonomous University of Mexico have created a floating robot called RoboKrill. Its appearance was borrowed from a shrimp called krill (Euphausia superba). For smooth movement in the underwater depths, the microrobot is able to imitate the kinematics of live krill. "Before this project, I did various researches aimed at understanding the role of plankton aggregation in the ocean. To this end, I conducted an experiment where I controlled the behavior of organisms using light signals. After that, I thought that it would be a good idea instead of externally controlling behavior of organisms, use a robotic system that has the same dynamic signature as floating living things," Monica M. Wilhelmus, one of the researchers who led the study, told TechXplore. In the future, RoboKrill may be used by biologists and environmental scientists to remotely study the marine environment and ... >>

Rapidly charged quantum battery 28.03.2022

Scientists from South Korea have developed a quantum technology that will speed up the charging of an electric car by 200 times. Researchers at the Center for Theoretical Physics of Complex Systems at the Institute for Basic Sciences (IBS) have turned to quantum entanglement to speed up the relatively slow charging of electric vehicle batteries. They suggested a way to charge all the energy cells at the same time. Despite the rapid development of the electric vehicle industry, their batteries still have a lower energy density than combustible fuel, and driving range is very dependent on this. Currently, it takes about 10 hours to fully charge the battery at home, and when connected to the fastest charging stations, the process takes 20-40 minutes. Waiting times remain a big disadvantage of electric vehicles compared to diesel or petrol vehicles, which take seconds to refuel. The researchers proposed a specific way to develop a quantum battery, as well as a definition ... >>

Bamboo will increase the strength of composite materials 27.03.2022

Scientists at the University of British Columbia have come up with a way to increase the strength of biocomposite materials using plastination. Canadian researchers have shown that adding 10% plastic bamboo to a fiberglass composite improves its ability to absorb impact energy. At the same time, the elastic properties of the material are preserved. "Bamboo is almost as strong as steel, but more flexible," says Abbas Milani, one of the co-authors of the study. "Due to its lightness, price and availability, this material has great potential for industry. Until then, it had only one big drawback." Biocomposite materials actively absorb moisture, which leads to rapid destruction. Scientists used plastination, traditionally used to preserve animal and human remains. This method preserves perishable biological samples. As a result of the treatment, water and fat in the tissues are replaced by a polymer. "The laminated bamboo composite was mixed with glass ... >>

AirPods and iPhone headphones will correct posture 27.03.2022

An iPhone app can help correct posture for those using AirPods. The PosturePal utility uses iOS 15's motion tracking feature to detect head position when using AirPods. The program warns you when you need to correct your posture. The design of the application is fun and simple - the user is greeted by a character who reacts to whether the user tilts his head correctly or not. And at the end of the session, evaluates. The program is available in the App Store for free, but offers $1,99 to unlock all features. Program developer Jordy Bruin says he only has access to AirPods Max, so he can't test his app on all AirPods Max headphones. The problem with regular AirPods and AirPods Pro is that many wear them incorrectly. For example, tilting them forward more than they should. This can be compensated in the application. ... >>

Wormhole transport network 26.03.2022

Scientists suggest that evidence for the existence of such a transport network may lie in the data already collected. There has long been an idea in science fiction that highly advanced alien civilizations could create a transport network of wormholes throughout the universe. And perhaps humanity has already found this network. Such assumptions are still just theories, but they intrigue some scientists. Astrophysicist from Nagoya University (Japan) Fumio Abe says that perhaps humanity has already recorded a similar network in the universe, but lost evidence in a sea of ​​other data. The expert believes that such evidence can be found if the data is reanalyzed. "If wormholes with a throat radius of 100 to 10 million km are associated with our Milky Way and are as common as ordinary stars, then we can detect them by reanalyzing data from past years," says Abe. According to the theory, wormholes are theoretical tunnels with two ... >>

Laser Air Defense System Light Shield 26.03.2022

The Israeli Ministry of Defense has unveiled a new laser system, whose task is to intercept enemy missiles, mortar shells and unmanned aerial vehicles. The system, the range of which is 10 kilometers, was called "Magen Or" - "Shield of Light". In the coming days, the Ministry of Defense is to sign an agreement with the Rafael concern, the main developer of Magen Or. ELTA is also involved in the project. The project is coordinated by the Directorate of Weapons Systems Development of the Ministry of Defense. This is a milestone in the development of air defense. Defense Minister Benny Gantz emphasized the cheapness of laser interception compared to missile interception. Some States in the region reportedly expressed interest in the system. The cost of development is hundreds of millions of shekels. It is assumed that the new air defense system will go into service with the IDF before the end of 2023. ... >>

Definition of transparent objects 25.03.2022

Robots and other automated systems have always had difficulty visually determining the three-dimensional shape of transparent objects, such as those made of glass. The new system solves this problem by using a laser to rapidly heat the desired surface. The Glass360Dgree system, developed by the German Fraunhofer Institute for Applied Optics and Precision Engineering, includes an infrared laser as well as two highly sensitive thermal cameras. Within fractions of a second, the laser moves over the entire surface of the object, slightly heating it. There is no risk that the object will melt or burn, as it only heats up by 3 °C. Although the absorbed thermal energy is stored in glass or other material for only a short time, this is enough for two cameras to simultaneously record changes in the thermal characteristic of the object from two angles. This data is analyzed by a computer system, which can then determine the three-dimensional shape and size of the object. ... >>

Bacteria produce fuel 25.03.2022

By studying the enzyme that bacteria use to catalyze this reaction, scientists have discovered key structures that control this process. True, experts do not yet know how to manage it. Specialists from Northwestern University (Chicago, USA) were able to find bacteria that produce fuel. So, an experiment was conducted with methanotrophic microorganisms. They consume approximately 30 million metric tons of methane annually. In this way, bacteria turn greenhouse gases literally into diesel fuel. Scientists still cannot understand how exactly this feature of bacteria can be used for the benefit of mankind. At the same time, while studying the enzyme with which bacteria catalyze this reaction, scientists have identified the main structures that control this process. According to the researchers, meth has strong bonds, and therefore an enzyme that can break these bonds is a real discovery. ... >>

Power transistors StrongIRFET2 24.03.2022

The new 2V and 80V StrongIRFET100 power transistors are Infineon's latest generation of MOSFETs. They are designed for a wide range of applications and can operate at both low and high switching frequencies. This new family complements the well proven StrongIRFET MOSFET offering higher performance. Compared to previous StrongIRFET devices, these products provide a 40% reduction in the "drain-to-source" resistance of the open channel RDS(on), resulting in an increase in bandwidth and an increased current rating, which reduces the number of transistors connected in parallel. For StrongIRFET2 transistors, relative to StrongIRFET, the gate circuit charge Qg is reduced by more than 50%. Therefore, due to the reduction in turn-on and turn-off times, transistors can be used at higher switching frequencies, and the requirements on the output characteristics of gate drivers can be reduced. ... >>

Robot conveying emotions while reading 24.03.2022

Scientists from the Faculty of Engineering, Information and Systems of the University of Tsukuba (Japan) have developed a robot assistant for reading text messages. It can help users control their mood when reading upsetting news. This device will improve social interactions as we move towards a world that increasingly uses digital communications. An emoticon in a text message is a quick and easy way to show your indignation to someone who is late for a scheduled meeting. It often lacks the human element that would accompany a face-to-face explanation or telephone conversation. According to scientists, we are probably more upset by the fact that we, our friends, cannot realize how angry and upset we are when we have to wait for them. Researchers from the University of Tsukuba (Japan) have created a hand-held robot called OMOY, equipped with a moving block driven by mechanical components inside with ... >>

own and common 23.03.2022

The desire to spend one's resources wisely and at the same time to deplete the general reserves is associated with the peculiarities of the work of pleasure centers. Let's imagine that we have a huge stock of something at home, but at the same time we go to the store and race with others trying to get the last packages of the same thing, from which all the shelves are bursting with us. On the one hand, the behavior is rather strange, on the other hand, it can be reasonably noted here that, due to the general uncertainty, it is wiser to save your reserves, and while there is an opportunity, use common resources. True, the same thing happens without any uncertainty. So, in 1968, it was noticed that public pastures in Scotland were trampled and eaten clean - farmers, at every opportunity, tried to drive their cattle to a common field so as not to touch their land, and as a result, public pastures simply became unusable. Another example is what is happening with the fishing industry: even if the fishermen have their big ... >>

High-speed Internet between the Earth and the Moon 23.03.2022

Startup company Aquarian Spac has received seed funding to deploy a high-speed communications network on the moon. Above Earth orbit, current communication relies on technology from the 1960s, making downloading lunar and space data an extremely slow process. Moreover, the lack of high-speed communication will create a serious obstacle to lunar operations and future exploration of Mars. Experts hope the Solnet system will help improve communications over Earth orbit, which John Rotondo, the startup's CTO, says is not enough to handle the growing number of proposed missions to the moon. Data is planned to be transmitted at a speed of 100 megabits per second. Solnet wants to launch in 2024. Rotondo also added that to ensure continuous coverage of the South Pole, the company intends to install a second satellite in 2025, but has not yet entered into an agreement to launch any of them. Aquarian Space is currently hosting ... >>

Dandelion Sensors 22.03.2022

Researchers at the University of Washington have created small sensors that, like dandelion seeds, can be carried by the wind over long distances. A group of scientists from the University of Washington (USA) have developed mini-sensors without batteries. They are similar to dandelion seeds in that they can be easily carried by the wind. Thanks to this technology, it will be possible to distribute such sensors over a large number of territories: to measure temperature, precipitation, humidity, etc. The tiny devices created are about 30 times heavier than a regular dandelion seed (the weight of a plant seed is 1 mg). However, they can still move up to 100 m in moderate wind. Each device has at least four such sensors, so the devices will be able to exchange information at a distance of up to 60 m. Instead of a battery, solar panels are installed in them, and more there are capacitors. Due to this, the sensors will be able to work all night. ... >>

Dogs, like people, can experience anxiety. 22.03.2022

Dogs, just like humans, can experience mental health issues, and that four-legged dogs can be a model for the study of human psychopathology and personality. Research scientists have shown that people have only 5 main personality traits ("big five"): extraversion, agreeableness, conscientiousness, neuroticism and openness to experience. These characteristics can be used to predict mental health, with neuroticism in particular being strongly associated with anxiety and other forms of psychopathology, and conscientiousness being negatively correlated with attention deficit disorders. Meanwhile, dogs are considered to have seven personality traits: insecure, energetic, learning-oriented, aggressive/dominant, sociable with people, sociable with dogs, and assertive. Dogs are said to have seven personality traits: insecure, energetic, learning-oriented, aggressive/dominant, social. ... >>

A substance has been discovered that accelerates wound healing 21.03.2022

Dutch biologists have isolated a substance from human saliva that significantly accelerates wound healing, which can help in the creation of drugs for those suffering from chronic ulcers, in the treatment of burns. "We hope that our discovery will ultimately benefit people suffering from incurable wounds such as foot or diabetic ulcers, as well as cuts and burns," said study lead author Menno Oudhoff. To study the effect of human saliva on wound healing, scientists cultured human epithelial cells from the inside of the cheek in cups. They then inflicted an artificial wound on the resulting cell film. After that, one cell culture was placed in an isotonic solution without foreign impurities, and the other - in human saliva. After 16 hours, the researchers found that the “wound” had completely healed in the saliva cup, while it remained open in the solution cup. It followed from this that saliva contains a substance that accelerates healing. ... >>

Metal foam - thermal insulator 21.03.2022

Scientists from the University of North Carolina (USA) have developed a lightweight metal foam that is able to insulate heat more efficiently than conventional metals and alloys. Composite metal foam consists of hollow spheres of carbon or stainless steel or titanium embedded in a metal matrix. The presence of air pockets allows such foam to effectively block heat, since heat spreads more slowly through air than through metal. Americans have learned to make composite foam in two ways. The first technology is based on casting materials with a low melting point (aluminum) around hollow metal spheres made of materials with a high melting point (steel). The second technology is based on the sintering of metal powder around finished hollow spheres. During the tests, foam samples measuring 6 x 6 centimeters and a thickness of about 1,8 centimeters were exposed to fire for half an hour and measured how long it would take to ... >>

Food from insects will create waste-free agriculture 20.03.2022

Insects are an excellent source of protein, requiring significantly fewer resources to produce compared to conventional agriculture. If a mealworm farm is given 2 kg of food, you can get a kilogram of edible protein. In the production of beef, the efficiency is incomparably lower, and greenhouse gases are also emitted. The production of insects for food and feed usually results in two by-products: insect exuvia and a kind of "meal". Exuviae are exoskeletons left over from insect moulting, and insect meal is mostly excrement and uneaten food. These two by-products could be potential alternatives to conventional fertilizers and pesticides. Scientists from Wageningen University in the Netherlands analyzed the possibility of producing food for humans and animals from insect by-products. In addition, these by-products can provide farmers with an organic soil supplement. Chitin is an important component of insect exuvium. ... >>

0,34nm gate transistor 19.03.2022

A group of Chinese scientists came up with an unusual transistor design. Thanks to their unique design, they made the world's smallest transistor with a gate length of just 0,34 nm. Further reduction of the gate length using traditional technical processes is in principle impossible, because we are talking about a gate length equal to the width of one carbon atom. The scientists called the new transistor a vertical sidewall transistor. The idea of ​​a vertical arrangement of the transistor channel, by the way, was also recently implemented by Samsung and IBM, which we once talked about. But the Chinese developers were able to surprise. The gate in the new transistor is a slice of one atomic layer of graphene, and its thickness, as you know, is equal to the thickness of one carbon atom, or about 0,34 nm. And the most amazing thing is that no modern lithographic scanners are needed to make a shutter of this length. All the necessary fine components are created using vacuum deposition processes. Ka ... >>

A new way to improve stem cell performance 19.03.2022

The researchers found that the "mother" of all stem cells (the so-called totipotent stem cells) has a reduced rate of DNA replication, and therefore is more likely to turn into other types of cells. This property has been replicated for stem cells grown "in vitro" - scientists are confident that a real revolution is coming for restorative medicine. Stem cells are "pure", template cells that, if necessary, can turn (scientifically - differentiate) into other types of cells when the need arises. However, some of them are more versatile than others. Multipotent stem cells are found in most adult tissues and can differentiate into a limited set of cell types. Pluripotent stem cells are at an earlier stage of the tree and are capable of dividing into virtually any cell type in the body. They, for example, can be found in developing embryos. It is noteworthy that the ability to transform is also m ... >>

UAV for underground reconnaissance 18.03.2022

Norwegian scientists have developed the RMF-Owl drone, designed for underground reconnaissance. He knows how to avoid obstacles and avoid collisions. The fact is that so far for robots to avoid obstacles in a confined space is a difficult task. The lack of access to the global navigation satellite system also interferes. The new drone was pre-equipped with a durable housing made of multilayer carbon foam. It has four motors and a PixRacer R15 flight controller. The drone itself is 38 centimeters long and weighs 1,45 kilograms. It is capable of flying autonomously for ten minutes. To determine the location, the drone uses lidar odometry and the CompSLAM simultaneous orientation and mapping system. He is assisted in reconnaissance by a local and global trajectory planner. In addition, the drone is able to map underground spaces and search for objects in them. The drone has already been tested in a Norwegian mine: it planned a route without collisions in a narrow corridor and for 6,6 m ... >>

Changing red blood cells to activate the immune system against covid 18.03.2022

Physicists, chemists and immunologists from McMaster University (Canada) have modified red blood cells to carry viral agents that can safely trigger the immune system to defend the body against the SARS-CoV-2 virus, creating a new potential vaccine delivery vehicle. The new method represents a completely unique approach to vaccination. Scientists removed all the "insides" of red blood cells and attached spike proteins to the outside of the cells to mimic the coronavirus. These empty cells can be filled with a large dose of viral proteins - without the genetic material of the virus. Once in the body, the modified cells activate the immune system and produce antibodies, a study in mice showed. At the same time, the new method of vaccine delivery causes few side effects compared to existing methods. "Some of the vaccines developed have shown side effects. This delivery platform opens up new possibilities for vaccines and therapeutics," I note. ... >>

There is also Wi-Fi and Bluetooth. ... >>

flight of spiders 17.03.2022

Never given wings by nature, many species of spiders have instead developed an uncanny ability to take to the skies using a few short strands of web projected from the back of their torso. How do they do it? To fly, spiders can use electric fields. This mechanism seems fantastic, but scientists have confirmed its possibility in theory. How exactly this method of invertebrate flight works has never been completely clear, although historically biologists have suggested that it probably has something to do with eddies of warming air near the Earth's surface. However, there is an alternative explanation for this phenomenon, which is gaining more attention as the evidence to support it accumulates. Instead of flying on air currents, spiders could take off into the sky on electric fields. Research conducted by scientists from the University of Bristol has shown that the electric fields generated by weather events are sufficient ... >>

New technology will increase the range of electric vehicles 16.03.2022

Scientists at the University of Central Florida have developed a composite material that expands the potential of lithium batteries for electric vehicles. The authors call their solution a "power suit" for batteries. With this technology, batteries in electric vehicles will be less prone to fire and increase the range of cars by at least 25%. For example, electric cars with a range of 320 km will be able to travel an additional 80 km, but their weight will not change. The hybrid device is based on a new generation material with an energy storage function. To construct it, engineers created positively and negatively charged layers of carbon fiber. The latter were stacked in an alternating order - thus, the scientists assembled a durable energy-storing composite. In addition, the new material received strips of carbon graphene with several types of metal oxides. After a series of experiments, the scientists found the optimal composition and created a "supercapacitor battery". With special graphene sheets, ... >>

Chemical composition of Viking weapons 14.03.2022

A group of scientists from the University of Nottingham attended to the study of the chemical composition of the metals from which the Viking weapons were made. This will allow specialists to determine its origin. The results of the study will help historians better understand the important events that changed the course of English history. According to a report from the University of Nottingham, experts are examining 90 Viking Age metal artifacts found at various times throughout England. Historians will examine weapons used by Scandinavian invaders at the Battles of Fulford in North Yorkshire and Babynington Heath, weapons from the Viking camp at Torksey in Lincolnshire, and artifacts found at the former Viking seaport of Meols. The weapons of the Vikings helped them in the conquest of various territories in Britain. No matter how many times the Vikings were defeated, from AD 793 when they first landed in Britain to AD 1066 when William the Conqueror became King of England, they ... >>

The UltraFusion architecture involves connecting two processor chips through a semiconductor substrate through which more than 10 connections pass. It was this approach that allowed Apple to get a single giant chip with 114 billion transistors, which, despite its composite nature, is recognized by all programs. ... >>

Improving the sensitivity of gravity wave sensors 12.03.2022

Physicists at the University of Western Australia have developed a new technology that aims to further increase the sensitivity of gravitational wave sensors, already the most accurate scientific instruments today. The introduction of new technology will raise the sensitivity to a level that previously could only be obtained by building new sensors, the dimensions of which exceed the existing ones. The technology uses a "symbiosis" of quasiparticles, which are quanta of sound vibrations called phonons, and photons of light from a special laser. The resulting quasi-particles of a higher order of complexity make their own oscillations with a frequency of billions of times per second, all this happens without any energy loss and is used to amplify the signal from the gravitational wave sensors. The main problem that did not allow earlier to implement something similar is that phonons, which are carriers of quantum information and act as ... >>

Chimpanzees see other people's intentions 11.03.2022

We distinguish between offenses committed intentionally and those committed by negligence or, for example, due to circumstances, and we treat offenses by negligence (or by necessity) more mildly. Chimpanzees do the same. German scientists experiment in which monkeys had to give a person a certain object, and in return receive a treat. The treat was of two kinds, better and worse. In some cases, the chimpanzee saw that a person has a choice of what to give them, and in some cases they saw that there is no choice, that a person gives only what he himself can take. Chimpanzees, as it turned out, were quite capable of distinguishing people's own bad intentions from the force of circumstances. If the experimenter gave them a worse treat, although he could well have given something better, the monkeys simply spat at him. If the experimenter showed the chimpanzees that he simply could not give them something more tasty, they were completely understanding. In another series of experiments, everything was more complicated: one person hid from others ... >>

Nanohousing for sun-loving bacteria 10.03.2022

Researchers at the University of Cambridge in the UK have 3D printed a grid of high-rise "nano-housing" in which sun-loving bacteria can grow rapidly. With these "houses," scientists have been able to extract more of the energy generated from photosynthesis from bacteria, which can be used to power small electronics - more than with traditional renewable bioenergy production methods. Cyanobacteria are large bacteria capable of photosynthesis. For several years, researchers have been trying to "reconfigure" the mechanisms of photosynthesis in cyanobacteria in order to extract energy from them. To grow, cyanobacteria need a lot of sunlight - for this they are well suited, for example, the surface of a lake in summer. And in order to extract the energy they produce from photosynthesis, bacteria must be attached to electrodes. A team from Cambridge has 3D printed special electrodes from metal oxide nanoparticles - in the form of highly branched, densely packed ... >>

PG&E CEO Patty Poppy said that the ability to use electric vehicles as a backup power source will be a significant advantage, as well as help in the fight against climate change. A similar project is currently underway by Ford Motor and Sunrun Inc. The latter is one of the leaders in the solar energy market. ... >>

Revealed the secret of gait dinosaurs 09.03.2022

Scientists from the University of Liverpool analyzed the footprints of sauropod dinosaurs in a geological formation in Arkansas. It turned out that huge dinosaurs, such as diplodocus, had a diagonal gait. This is how a modern hippopotamus moves. An analysis of fossilized dinosaur footprints in the De Queen Formation in Arkansas, USA, showed that sauropods had a diagonal gait. This means that the paws, located diagonally from each other, took a step at about the same time. That is, each step of the front leg went in tandem with the back leg on the opposite side, or these movements were very close. A similar gait is observed in living hippos and no one else on Earth. Sauropods were among the largest animals that ever lived on our planet. Some of them weighed as much as 14 African elephants. These herbivorous dinosaurs lived on Earth between 200 and 66 million years ago. "These huge dinosaurs used a diagonal ... >>

Algorithm for Predicting Turbulent Flows in the Solar Atmosphere 08.03.2022

Scientists from the National Astronomical Observatory of Japan have developed a deep learning system for neural networks to detect hidden solar fluxes. The knowledge of scientists about our luminary is very limited, which is explained by the complexity of its study. It is relatively easy to observe the temperature and motion of the solar plasma, which is periodically ejected perpendicular to the surface of the star. The gas that forms this plasma is so hot that only electrons and ions can be present in it. However, it is very difficult to determine the surface movements occurring on the Sun. Japanese scientists have developed a deep learning neural network method to obtain hidden information about turbulent motion from observations of the Sun. Scientists were able to determine that information about the surface motion of solar matter can be extracted from data on temperature and vertical flow. The neural network was trained on three different plasma turbulence simulations. As a result, she correctly predicted the horizon. ... >>

Strength training reduces the risk of death 07.03.2022

Regular exercise that strengthens muscles reduces the risk of death from certain diseases, said Japanese scientists from the universities of Tohoku and Kyushu. Muscle-strengthening exercises include weight lifting, push-ups, sit-ups, resistance band work, and even gardening. Experts analyzed 16 studies conducted in the United States, England, Scotland, Australia and Japan, which involved from 4 to 480 thousand people of different ages. All studies have examined the effects of aerobic and strength exercise on the human body. They found that 30-60 minutes of weekly exercise was associated with a 10-20 percent lower risk of death from cardiovascular disease, cancer, diabetes, and lung disease. The scientists noted that the results may not be completely accurate because the studies they studied were observational, not clinical, and were based on a subjective assessment of muscle strengthening activities. ... >>

Mindful sleep preparation helps you fall asleep 06.03.2022

Stress keeps you awake, and many try to cope with this with medications that are not always safe for health. Researchers at the University of Michigan have found that there is another way to get yourself to sleep that is safer and possibly more effective. Getting ready for sleep, we perform a series of actions: we make the bed, brush our teeth, set the alarm clock, etc. This ritual is repeated every day, and is believed to help the brain calm down and get ready for sleep. However, so far no one has shown directly that there is a causal relationship between the "pre-sleep" ritual and the quality of sleep. Meanwhile, animals also behave in a certain way before going to bed - just watch a dog or a cat, how they spin in place, trampling a hole in a soft bedding or on a sofa, lick themselves and go through different poses before falling asleep. The researchers decided to observe mice that are preparing to go to sleep, and to observe not only the behavior of the mice themselves, but also ... >>

Organic rechargeable household batteries 06.03.2022

Australian and Chinese scientists have developed a 2,8V all-organic polymer battery. It is an ideal alternative to traditional metal-based batteries in particular to reduce environmental pollution. "Starting with small household batteries, we already know that organic redox materials are typical electroactive alternatives due to their intrinsically safe, lightweight and structurally tunable characteristics and, most importantly, their sustainability and environmental friendliness," says Zhongfang Jia, scientific director of the Nanotechnology Institute at Flinders University. The research team developed a battery based on silver terephthalate (instead of sodium terephthalate, which is used in lithium-ion batteries). The cell voltage is 2,8 V, the specific capacity is 43 mAh/g. The team is now looking to improve on these characteristics and create a fully biodegradable battery with an e-voltage. ... >>

Mate significantly increases the risk of cancer 05.03.2022

Tea is one of the most popular drinks in the world. But not every tea is equally good. So a new study has shown that regular consumption of one type of tea can increase the risk of developing several types of cancer. This is mate tea. Proponents of its use believe that herbal tea helps to overcome fatigue, helps to lose weight, relieve headaches and ease depression. But according to the Mayo Clinic, the evidence to support this is limited. Studies have shown that drinking the popular herbal drink can have adverse effects. The scientists reviewed data from ten studies that examined the potential risks of drinking mate tea. A study found that regular tea consumption can increase the risk of lung cancer and various types of digestive tract cancer, including esophageal cancer, liver cancer, colon cancer, and stomach cancer. Mate has also been shown to triple the risk of developing esophageal cancer. The use of mate, infusion of the herb Ilex paraguariensis, ... >>

40-kilowatt wireless electric vehicle charging 04.03.2022

The idea of ​​integrating wireless charging stations for electric vehicles into urban infrastructure has been in the air for a long time, since as unmanned electric vehicles become more widespread, their use will increasingly justify itself. The Swedish company Volvo Cars, as part of an experiment, began testing wireless taxi charging stations capable of transmitting more than 40 kW without connecting via cable. In Gothenburg, Sweden, in addition to Volvo itself, taxi operator Cabonline and wireless charging station manufacturer Momentum Dynamics will be involved in this experiment. Modified crossovers Volvo XC40 Recharge will be able to recharge the traction battery, simply by being placed on specially equipped sites in one of the districts of the city. Since the exact mutual positioning of the transmitting and receiving circuits is very important in this case, Volvo will use its surround view system to accurately position the car above the charger built into the road surface. Efficiency ... >>

Developed a simple way to create flexible diamonds 04.03.2022

Hard as diamond and flexible as plastic, the highly sought-after diamond nanofibers could revolutionize our world - if they weren't so difficult to manufacture. Scientists led by Carnegie's Samuel Dunning and Timothy Strobel have developed an ingenious technique that predicts and directs the orderly creation of strong yet flexible diamond nanofibers, overcoming a number of existing problems. This innovation will make it easier for scientists to synthesize nanofibers, an important step towards future applications of the material. Diamond nanofibers are ultra-thin one-dimensional carbon chains, tens of thousands of times thinner than a human hair. They are often created by squeezing smaller carbon rings together, forming the same type of bond that makes diamonds the hardest mineral on our planet. However, instead of the three-dimensional carbon lattice found in a normal diamond, the edges of these strands are "capped" with carbon-hydrogen bonds, which make the entire structure flexible. Because it's new ... >>

It is expected that this year the volume of deliveries of virtual and ... >>

Nostalgia reduces physical pain 03.03.2022

A new scientific study by scientists from China proves the ability of memories of the past to reduce physical pain in the human body and increase stress resistance. The fact is that the part of the brain responsible for pain is also responsible for the perception of nostalgia. Thanks to the tomograph, researchers at Peking University have proven that nostalgia can significantly improve a person's health. Nostalgia is a complex emotion involving the self, autobiographical memory, and reward. It turned out that the "taste of the past" is able to cheer up a person. For example, it could be old letters, cartoons, or candy from childhood. When pain is added to the occasion, experience points to the essential role of the thalamus, the site of information transit between the body and the cerebral cortex. This area of ​​the brain responds to both nostalgia and pain information. By integrating a positive desire signal into a pain signal, the thalamus appears to play a key role in this pain relief. ... >>

An effective way to clean waste water filters 02.03.2022

Chinese scientists have developed reusable nanoparticle catalysts that include glucose to help break down contaminants inside sewage filters efficiently without damaging the filters themselves. As a rule, dirty sewage filters are cleaned with strong acids, alkalis or oxidizers. Chlorine-containing oxidizers, such as bleaches, can break down the most persistent organic debris. But they also damage the polyamide membranes that are used in most commercial nanofiltration systems and produce toxic by-products. A milder alternative to bleach is hydrogen peroxide, but it is slow to break down pollutants. Previously, scientists combined hydrogen peroxide with iron oxide to form hydroxyl radicals, which increase the effectiveness of hydrogen peroxide in a process known as the Fenton reaction, which can destroy many organic substances. However, in order to ... >>

Environmentally friendly fuel based on carbon dioxide 02.03.2022

Researchers from the University of Cambridge, together with specialists from the University of Nova de Lisboa in Portugal, have developed a method for obtaining environmentally friendly fuel from carbon dioxide by electrolysis. Enzymes secreted by bacteria are used as catalysts in this process. The problem is that enzymes are very sensitive to the chemical environment, and when it changes, they stop working. In this case, the process of fuel formation is seriously slowed down. Experiments conducted in the laboratory have shown that the use of these enzymes as a catalyst increases the efficiency of fuel production by 18 times. The scientists were able to increase the efficiency of electrolysis by fine-tuning the solution conditions to change the local environment of the enzymes. "Enzymes have evolved over millions of years to be extremely efficient and selective - and they're great for fuel production because they don't have unwanted by-products," he says. ... >>

solar wind magnetometer 01.03.2022

The Sino-European joint space mission Solar Wind Magnetosphere Ionosphere Link Explorer (SMILE) has successfully conducted extensive testing of its payload magnetometer in Europe. The tests show that the functions and performance of the magnetometer subsystem integrated with the payload module are consistent with mission requirements and that researchers from China and Europe have reached agreement on development specifications, technical process, test methods and evaluation standards. The magnetometer is a complex of high-precision equipment for registration of a space-vector magnetic field. It is used to detect the XNUMXD cosmic magnetic field vector and obtain detection data on the magnitude and direction of the solar wind magnetic field. According to the Chinese Academy of Sciences (CAS), the magnetometer arrived at the European Space Research and Technology Center (ESTEC) of the European Space Agency (ESA) last month for ... >>

Earthworms can replace synthetic fertilizers 01.03.2022

Researchers at University College Dublin have uncovered new information about the importance of soil dwellers to nutrient-consuming plants. The findings suggest a previously undiscovered shortening of the soil nitrogen cycle, in which earthworms, when active, quickly enrich the soil and plants with nitrogen released by their mucus. The role of soil animals such as earthworms in nutrient cycling has traditionally been considered beneficial but indirect, slow and cumulative. In the lab and in the field, a team of researchers from Ireland, Germany and China were able to track nutrient transfer from earthworms to soil, wheat germ and aphids using a technique called stable isotope tracers. They found that earthworm-derived nitrogen was absorbed by green flies after two hours in the lab and 24 hours in the field. The researchers were amazed at how quickly nitrogen ... >>

Modular Robots ElectroVoxel 28.02.2022

A group of scientists from the Computer Science and Artificial Intelligence Laboratory (CSAIL) at the Massachusetts Institute of Technology (MIT) and the University of Calgary have created a system of modular robots that can take on various forms. ElectroVoxel robots don't have motors or moving parts, they just use electromagnets to move around each other. Each edge of these cube-shaped robots is an electromagnetic ferrite core wrapped in copper wire. Each side of the ElectroVoxel is about 60 millimeters long, and the total cost to build the robot is only 60 cents. The shape of the robot changes when there is a change in the polarity of the magnet. Circuit boards and electronics inside each hub control the direction of current from each electromagnet. To control the robots, a software scheduler is used to plan reconfigurations. Developers say specific magnets can be isolated to control speed ... >>

Hydrogen peroxide rocket fuel 28.02.2022

Hydrogen peroxide is a less toxic alternative to hydrazine, a widely used aerospace fuel for low and medium thrust engines. Hydrazine is a carcinogen and requires additional equipment for its use. And this increases the price of both the fuel itself and the launch of missiles. At the same time, hydrogen peroxide is non-toxic to humans and is widely used in everyday life, for example, for bleaching hair or treating wounds. But to produce fuel from hydrogen peroxide, a highly efficient catalyst is required. It is usually created using expensive precious metals such as silver or platinum. University of Canterbury Chemical and Process Engineering PhD student Simon Reid has collaborated with Callaghan Innovation to develop a catalyst with a special ceramic layer that can be 3D printed. It increases the efficiency of processing concentrated hydrogen peroxide into rocket fuel. Passage of liquid hydrogen peroxide over a layer of kat ... >>

Bone repair with sound 27.02.2022

Researchers at the Royal Melbourne University of Technology have learned how to turn stem cells into bone using sound waves. They developed a microchip that generated sound for a certain amount of time, which contributed to the transformation of cells. The scientists used stem cells derived from adipose tissue and exposed them to 10 megahertz sound signals for ten minutes a day, five times a week. This accelerated the formation of cells into bone. Sound waves can shorten a patient's treatment time by several days. This method is cheaper and easier to use than those that require special preparations and skills. Once stem cells have begun to be generated into bone, they can be injected into the body or applied to an implant ready for new bone to grow. Scientists will continue to work on how to use the invention in practice - it will speed up the regeneration process. ... >>

Squid cage camouflage 26.02.2022

Researchers at the University of Pennsylvania have developed an artificial version of squid and octopus cells called chromatophores. In nature, these cells help cephalopods to change their color to match the shades of the environment. Chromatophores are special cells of octopuses and squids. Inside they contain elastic membranes that can expand and contract in response to external stimuli. This allows the clams to camouflage themselves in the environment and also scare away other predators. In the study, the engineers also used thin and flexible membranes made from a liquid crystal polymer network. The membranes are placed over tiny cavities, each of which can be "inflated" to the desired volume. As the membrane stretches, it decreases in thickness and changes color. As a result, it turned out to create a completely artificial chromatophore, which is able to instantly change its color. The scientists then measured the pressure levels needed to give the chromatophores each desired color. This allowed them to ... >>

Tracking satellites and space debris 26.02.2022

The US National Oceanic and Atmospheric Administration (NOAA) this week unveiled a prototype satellite collision avoidance system called the Open-Architecture Data Repository (OADR). It should help in tracking potentially dangerous situations, which will be especially useful against the backdrop of the rapid growth in the number of satellites in Earth orbit and space debris. The OADR system is a cloud-based database that collects data on the movements of all satellites and warns in a timely manner if there is a possibility of a collision of any vehicles and space debris. It is assumed that OADR will receive data from numerous scanning facilities located on the surface of the planet. After processing the received data, the system will form a picture of what is happening in orbit, which will be used to assess the likelihood of hazardous situations. If necessary, OADR will notify constellation operators, giving them a few days ... >>

A battery the size of a grain of salt 25.02.2022

A group of German scientists led by the Chemnitz University of Technology has created the smallest battery in the world - it is less than one square millimeter in diameter. Such a battery has a capacity of 100 microwatt-hours per square centimeter. Subsequently, it can be used to power small sensors in the human body, such as those that monitor oxygen levels or monitor the body's recovery after surgery. During the creation of the battery, scientists used the same method that Tesla uses when creating its own batteries. Thin layers of polymeric, metallic, and dielectric materials were deposited on the surface of the stretched plate. When they begin to flake off from each other due to mechanical stress, a voltage drop occurs. This method is compatible with established technologies for the production of microcircuits, and also allows the production of miniature batteries with high performance. ... >>

Ultra-precise atomic clock 24.02.2022

A group of physicists at the University of Wisconsin-Madison announced the creation of super-efficient atomic clocks. The device measures time so accurately that it loses only one second in 300 billion years. The watch will enable more accurate measurements of gravitational waves, dark matter and other physical phenomena. An atomic clock is a clock that tracks the resonance of the frequencies of atoms, usually cesium or rubidium. This allows such watches to measure time with high accuracy. So, NASA conducted an experiment in which the atomic clock Deep Space Atomic Clock worked in orbit for two years. Atomic clocks work by keeping track of the energy levels of electrons. When an electron changes energy level, it absorbs or emits light at a frequency that is the same for all atoms of a particular element. Optical atomic clocks keep time using a laser finely tuned to this frequency, and require some of the world's most sophisticated lasers to measure time accurately. In the ho ... >>

Nanotechnology for strengthening concrete 24.02.2022

American scientists have synthesized a nanotechnological sealant that can significantly strengthen concrete. Researchers from the University of Washington have solved the problem of the strength of concrete, which is used to build and strengthen various buildings. Engineers turned to nanomaterials, thanks to which they were able to improve the quality characteristics of concrete and create a super-strong mixture for construction. Experts said that the destruction of concrete structures occurs for two reasons: due to the effects of moisture and the influence of various salts. The authors of the study used two nanomaterials - graphene oxide and montmorillonite nanoclay - added to a conventional silicone-based sealant. Under laboratory conditions, the resulting mixture was stronger than concrete: water-repellent properties increased by 75%, protection against salts - by 44%. ... >>

seaweed eggs 23.02.2022

California-based smart food maker Fiction Foods is taking cellular farming to the next level with a new, animal-free egg alternative. The company was founded by plant-based food pioneer Brendan Brother with the goal of creating the most sustainable way to produce the most nutrient dense protein. The main criterion for the selection of Fiction Foods ingredients is the ratio of nutrients and resources. That is why Euglena was chosen as the basis for the new flagship Performance Scramble Liquid Egg. "The only nutritional requirement for euglena is carbohydrate, which can be taken from pea starch, a by-product of pea protein production," the developers explain. Euglena turns the unused by-product into an animal-quality protein with almost zero environmental cost. "Performance Scramble is not a fake egg, but a brand new product containing high quality ... >>

Mars laser catapult 23.02.2022

In Canada, they proposed sending astronauts to Mars with a laser "catapult". Local scientists believe that with the help of a revolutionary idea, they can reduce travel time to 45 days. This is many times greater than the performance that existing technologies are capable of - the NASA Perseverance rover traveled to the Red Planet in just over 7 months. The idea is to build a laser-thermal propulsion system on Earth from a group of infrared lasers with a diameter of ten meters and a power of 100 megawatts. Approximately 80 American households consume this much. An orbiting ship would have a reflector that would aim beams from the planet's surface into a heating chamber filled with hydrogen plasma. As the temperature rises, it will be ejected through the nozzle, thus creating powerful thrust. As planned, when the radiation subsides, the ship will accelerate to 17 km / s. However, this is also the main snag - researchers still have little idea how to slow down at a point on ... >>

transistor molecule 22.02.2022

Swedish scientists have succeeded in making a simple hydrocarbon molecule with the function of a logic gate, like those that power transistors. This discovery allows us to get closer to the creation of electrical components with a size of several nanometers. "We have developed a simple hydrocarbon molecule that changes shape and at the same time turns from non-conductive to conductive, conductive under the influence of an electric potential. The secret of success was the creation of a so-called anti-aromatic ring in the molecule, so that it became more reliable and able to accept and transmit electrons," - said one of the researchers, Daniel Strand. Many organic molecules are made up of six carbon aromatic benzene rings. However, these molecules do not change their properties or shapes when exposed to electricity. So scientists turned to rings of eight carbon atoms. If two electrons are introduced into such a molecule, it becomes flat and conductive, although up to e ... >>

Blurred Text Decoder 22.02.2022

To preserve confidentiality, pixelation is often used - "smearing" text into separate dots. But as it turned out, this may not be enough to maintain the secrecy of correspondence. Cybersecurity specialist Dan Petro has developed a software tool that can be used to easily restore "blurred" characters. The idea of ​​creating an algorithm came to an enthusiast after the IT company Jumpsec Labs launched a competition to decipher pixelated text. Although there are already solutions on the market that can improve pixel images of people or landscapes, they are not suitable for small characters like letters. Therefore, the specialist decided to create his own tool - and his idea was a success. An open source algorithm called Unredacter is available for review. Publishing his brainchild, the specialist recommended that users no longer use pixelation or blur to hide information. According to him, the best way to defend will be black p ... >>

Yeast medicines 21.02.2022

Scientists have edited the yeast genome to produce a key ingredient in drugs for age-related dementia and Parkinson's disease. Researchers at Imperial College London and the National University of Singapore have been able to turn friendly mushrooms into biofactories to produce a chemical compound, an alkaloid used in drugs for dementia and Parkinson's disease. Today, this alkaloid is obtained from extracts of ergot, a parasitic fungus that infects wheat and rye. From 10 to 15 tons of compound are produced annually. Growing ergot in such volumes for medical purposes harms the environment. Therefore, the researchers decided to try an alternative method using yeast. The scientists isolated genes from ergot and inserted many variations of them into the genome of baker's yeast to produce a cell that could make a key drug ingredient. "Yeast has been a key part of human civilization for thousands of years, helping us bake ... >>

Self-cleaning bioplastic 20.02.2022

The problem of plastic pollution is acute in all countries. Its particles are found deep in the oceans and high in the mountains. Scientists at the Royal Melbourne Institute of Technology Australia (RMIT) have developed a transparent bioplastic from starch and cellulose. This material is perfect for packing fresh food or ready meals. At the same time, it is not afraid of exposure to moisture or dirt, as it has a special structure inspired by the lotus leaf, from which water simply rolls off. Bioplastics from Australian researchers do not need industrial processing, easily decomposing in the soil naturally. “We have designed this new bioplastic with large-scale production in mind, with ease of fabrication and ease of integration into industrial manufacturing processes... We have replicated the phenomenally water-repellent structure of lotus leaves to create a unique type of bioplastic that combines strength and degradability,” said Mehran Ghasemlow, ... >>

Ultra-compact electric vehicle iEV Z 20.02.2022

The Danish company iEV Motors has introduced a very compact electric car iEV Z, whose dimensions are 78 cm wide, 145 cm high and 198 cm long - the latter figure may vary depending on the needs of the owner. The machine weighs only 220 kg. If the owner of the iEV Z needs to put a passenger in the passenger compartment, the drives of the electric vehicle fold out the second seat behind the driver's one and lengthen the body up to 235 cm. In addition to the passenger, luggage can also be loaded into the passenger compartment, increasing the length of the car to 275 cm. . You should not expect advanced technical characteristics from such an electric car: there is only one motor with a power of 1 kW (1,36 hp), which accelerates the car to 45 km / h, and a battery with a capacity of 3,3 kWh provides a cruising range of 100 km and fully charged in 3 hours. Solar panels on the roof serve as an additional power source. If local laws allow, says the automaker, this electric ... >>

The share of renewable energy sources is growing 19.02.2022

In the European Union, renewable energy accounted for an average of 2020% of total energy used for space heating and cooling in 23, according to an update from Eurostat. The use of renewable energy sources for these needs in the EU is steadily growing. In 2004, RES accounted for 12% of the energy consumed for space heating and cooling, and in 2019 it was already 22%. The level and growth of renewable energy consumption for heating and air conditioning is similar to that observed for renewable energy generation in the EU. In particular, in 2004 the share of renewable sources in the EU accounted for 10% of total energy production, and in 2020 - 22%. Among Member States, Sweden stands out, where two-thirds of the energy (66%) used for heating and cooling in 2020 came from renewable sources - mainly from biomass and heat pumps. Estonia and Finland (58% each), Latvia (57%), Denmark (51%) and Lithuania (5 ... >>

Vacuum particle-antiparticle pair 18.02.2022

For the first time in history, scientists from the University of Manchester have made direct experimental observations of the so-called Schwinger effect, a subtle effect that can only occur in the region of high-energy cosmic events such as supernova explosions, neutron star collisions and black holes. By applying very high potential electric currents to specially designed graphene devices, scientists have been able to create particle-antiparticle pairs from literally nothing, from a deep vacuum. According to existing theories, vacuum is a completely empty space, in which there is no matter and even elementary particles. However, 70 years ago, Nobel laureate Julian Schwinger predicted that the strongest electric and magnetic fields could break the basis of the vacuum (space-time continuum), leading to the spontaneous appearance of particle-antiparticle pairs, the so-called Schwinger pairs. Such an effect requires the participation of forces ... >>

Superelastic alloy that maintains rigidity at high temperatures 18.02.2022

A research team led by scientists from the City University of Hong Kong (CityU) has discovered a first-of-its-kind superelastic alloy that can retain its rigid structure even when heated to 726,85°C or higher. The alloy can be used in the production of high-precision devices for space flights. Usually, metals soften when heated. But this does not apply to the new alloy - Co25Ni25(HfTiZr)50. It belongs to the elinvar type, a group of alloys whose elastic properties are little affected by changes in temperature. When the new alloy is heated to 726,85°C or more, it remains as stiff or even slightly stiffer than at room temperature. At the same time, it expands without any noticeable phase transition, the authors of the work note. Why it happens? It's all about the structure of the lattice: it is very much distorted. Due to the combination of unique structural features, the high-entropy alloy has a very high energy barrier. ... >>

Ecological production of rare earth elements from waste 17.02.2022

Rare earth elements (REEs) are extremely important for the consumer electronics, chemical and automotive industries. Based on Nd, Y, Sm, Er, Eu with Fe-B, alloys with record magnetic properties are obtained, so they are used in engines for electric vehicles and hybrids. Others are needed to create components for smartphones, hard drives, flat screens, etc. Instant Joule heating technology was developed several years ago to obtain graphene from any solid carbon source, and is now being applied to three sources of rare earth elements: coal fly ash, bauxite residues and electronic waste. But the industrial extraction of rare earths is associated with leaching due to the use of acid, which is harmful to the environment. A group of scientists from the American Rice University has developed a method for obtaining REE from waste efficiently and with a minimum of acid. To do this, fly ash and other materials, combined with soot, were placed in a quartz tube. Zat ... >>

Biohybrid fish from human heart cells 17.02.2022

Researchers at Harvard University and Emory University (USA) have developed the first fully autonomous biohybrid fish from heart muscle cells derived from human stem cells. Artificial fish swims, recreating the muscle contractions of the heart, according to the press service of the Harvard School of Engineering and Applied Sciences. John A. Paulson. The first self-contained biohybrid device is made from cardiomyocytes (heart muscle cells) derived from human stem cells. It mimics the shape and movements of the zebrafish. Unlike previous devices - a biohybrid jellyfish and an artificial ray made from rat heart cells - the biohybrid zebrafish has two layers of muscle cells, one on each side of the tail fin. When one side is compressed, the other is stretched. In response to the stretch, a protein channel opens, causing a contraction that triggers the stretch, and so on. A closed loop is created, thanks to which the fish can move more ... >>

Smartphone-chameleon 16.02.2022

Smartphone maker Tecno, part of Transsion Holdings, has unveiled the world's first polychromatic photoisomeric technology. The idea is to make smartphones brighter by allowing them to change their appearance depending on external conditions. Smartphones are already on the market that can change their color from one to another under the influence of sunlight. With its polychromatic photoisomeric technology, Tecno has gone even further. The new development is based on the effect of breaking and restoring the chain of photosensitive molecular bonds under the influence of ultraviolet light. As a result, colorless molecular groups become chromogenic and then colorless again. Tecno technology allows the smartphone to change its color not from one to another, but to several at once, which is clearly shown in the demo video. The manufacturing process of such a surface consists of 22 steps and requires nanometer-level precision. To achieve the desired result, the company ... >>

Direct lithography of optical systems based on perovskite 16.02.2022

Direct lithography of perovskite nanocrystals inside glass with the ability to adjust the composition was implemented by a group of researchers from China. Perovskites are a type of mineral that has special optical properties. Because of this, it is well suited for the creation of fuel cells and electronic devices such as cathodes and LEDs. But as the researchers note, the processing of minerals usually involves the use of special solutions, which leads to low structural stability. The researchers developed a new approach - using ultrafast laser pulses to perform 3D direct lithography of perovskite NCs with the ability to tune the composition. The impact of the laser also increases the pressure, resulting in the separation of the liquid nanophase. The scientists carried out their experiments on oxide glasses made of lead, cesium and halide. They then used a laser to engrave 3D patterns into the glass mass. They managed to etch pixel ... >>

Nanopores heat up as ions pass through them. 15.02.2022

Japanese scientists from the Institute of Scientific and Industrial Research (SANKEN) of Osaka University found that nanopores heat up when an ion stream passes through them. This phenomenon is explained by Ohm's law and can be useful in DNA sequencing, and it also presents prospects for the use of nanopores in biosensors. Nanopores are small holes in a membrane. Their size is so small that only one of the DNA strands or a virus particle can pass through one pore. Now nanopores are being studied for use in sensors. Typically, an electrical voltage is applied to force a substance to pass through a nanopore. Then the ions contained in the solution can pass through the pore. However, it is known that electrical energy is converted into thermal energy through resistance. This is the Joule-Lenz law. This phenomenon has not been previously studied in nanopores. Japanese researchers have studied how the application of electrical voltage affects the heating of a nanopore. They used a thermocouple (temperature sensor, ... >>

Artificial muscles from natural proteins 15.02.2022

A group of researchers from the University of Freiburg have succeeded in developing artificial muscles that use the body's natural processes. Scientists have demonstrated an autonomous flexor muscle that moves by consuming chemical fuel, similar to its counterparts in humans or animals. Our artificial muscle is still a prototype. However, the high biocompatibility of the material and the ability to adjust its composition to suit specific tissues and technological applications could pave the way for future applications in reconstructive medicine, prosthetics, pharmaceuticals or soft robotics, says Steven Schiller. In the past, scientists have used natural proteins to build artificial muscle systems by embedding them into tiny molecular machines or polymers. However, they failed to develop completely biological synthetic muscles. The natural protein used by the Freiburg team is based on a naturally occurring fibrous protein called elasti ... >>

Education influences life expectancy 14.02.2022

Based on data from an experiment that covered 31 European countries, scientists from the Vienna University of Economics and Business came to the conclusion that in countries where the population does not have equal access to higher education, representatives of social groups that do not have the opportunity to receive it live less than those with who has this opportunity. This study confirmed the conclusion made in 2016 by the scientist Isaac Sasson. He found that college graduates outlived their less educated fellow Americans by an average of 10 years. Moreover, within this group, the difference in the achieved life spans was observed to be the most insignificant. More precisely, from the materials published by him on the website of the London School of Economics and Political Science (LSE) it follows that for educated women, the excess of normal life expectancy was noted at the level of 9,3, and for men - at the level of 11,9 years old. ... >>

Two-dimensional polymer is stronger than steel 14.02.2022

American materials scientists have learned how to synthesize two-dimensional polymers, which, unlike others, are able to assemble in layers instead of forming one-dimensional chains. Made from melamine, the two-dimensional polyaramid is six times less dense than steel, but nearly twice as strong. The manufacturing method is scaled - the material self-assembles in solution. Chemists strive to obtain a covalently bonded, highly periodic molecular structure one monomer thick. "Molecular carpet" is a good term for a two-dimensional polymer. Real two-dimensional polymers will be one monomer thick and have a regular structure. The big problem in creating XNUMXD polymers is that, even though there are strategies for synthesizing such structures, the XNUMXD spherical counterpart grows much faster. That is, only the desired molecular structure polymerizes, it will quickly be overtaken by the already familiar three-dimensional structure, for the creation of which it is enough ... >>

Effect of stress on brain size 13.02.2022

Stressed people over 40 perform worse on mental tasks and remember less compared to peers who have lower levels of cortisol, the stress hormone. How did American researchers come to this conclusion? High levels of cortisol in the blood may indicate a smaller brain size in such people. Scientists measured the level of cortisol in more than 2 thousand subjects, and then made them an MRI of the brain. So, even before the onset of any symptoms in people after 40 years of age with high levels of stress, a decrease in the ability to remember and a decrease in brain size were recorded. "The fast pace of modern life means higher levels of stress, and when we are stressed, cortisol levels rise as the survival mechanism kicks in," Dr. Seshadri explained. Experts also point out that doctors should pay more attention to stress-prone patients and tell them how to reduce anxiety levels. In particular, this requires ... >>

The machines are built by robotics manufacturer Ghost Robotics, known for their Ghost Vision 60 robot. DHS test dog robots are equipped with cameras and sensors for inspections and programs ... >>

Bacteria improve plant growth and enrich the soil 12.02.2022

Cover crop plants, clover, grown in soils similar to those of Mars, have shown significant growth in the process of infection with symbiotic nitrogen-fixing bacteria. A researcher from the University of Colorado (USA) Franklin Harris, together with colleagues, presented the results of the study in the publication PLOS ONE. As the Earth's population grows, researchers are exploring the possibility of farming Martian soil, or "regolith." Regolith lacks some key nutrients, including certain nitrogen-containing molecules that plants need to live. Therefore, agriculture on Mars will require a strategy to increase the amount of these nitrogen compounds in the regolith. The scientists suggest that the bacteria could play a cost-effective role in increasing the fertility of Martian soils. On Earth, soil bacteria help convert or "fix" atmospheric nitrogen into molecules that plants need. Some of these microbes have a symbiotic relationship ... >>

artificial tooth enamel 11.02.2022

Scientists from Beihang University in Beijing were able to create high-quality artificial enamel. The new material can be used not only in dentistry, but also in the construction of earthquake-resistant buildings, the manufacture of pacemakers, and also for bonding damaged bones. Tooth enamel is the thin outer layer of teeth and the hardest biological material in the human body. Tooth enamel is an ideal model for developing artificial nanomaterials that mimic the properties of biomaterials, but accurately reproducing enamel is challenging. Scientists from China have developed an analogue of enamel, consisting of assembled hydroxyapatite nanowires with segments of an amorphous intergranular phase. Artificial tooth enamel has been designed to closely mimic the composition of natural material, replicating the shapes and sizes of biologically found components and the organization of their interfaces. Scientists tested the new material by applying it to various objects ... >>

The sandpaper-like solar cell is based on the monograin powder technology developed by TalTech researchers, where the solar cell consists of thousands of small 50 micrometer diameter crystals embedded in a polymer in one continuous layer. Microcrystals absorb sunlight. To transmit solar energy, these microcrystals are covered with buffer and window layers. In this way, each crystal works like a small individual solar lamp. ... >>

Electronics will evaluate the level of sweetness of food and drinks 09.02.2022

Food and beverage companies cannot accurately determine how sweet their product is, so researchers continue to look for ways to measure sweetness levels. So far, tasters have coped with this task, but the perception of taste buds is not always accurate. In human language, sweet compounds interact with the Venus flytrap domain. Scientists from Korea have used bacteria to create copies of it. They were deposited in a thin layer on several gold electrodes interconnected by carbon nanotubes. When sweet solutions were applied to the device, the electric current flowing through it decreased - the greater the concentration of sweetness, the greater the current drop. A prototype bioelectronic tongue has already been used to evaluate the sweetness of apple juice and sweetened chamomile tea. Its sensitivity turned out to be 10 times higher than that of previously developed bioelectronic systems. It has been proven that excessive consumption of harmful sweets usugu ... >>

Flying robot the size of an insect 09.02.2022

Scientists from the University of Bristol (UK) have developed small drones that can fly by flapping their wings. The achievement was made possible by the use of an unprecedented electromechanical principle for propulsion of miniature wings, which does not require a traditional transmission. Thanks to the unique development of British scientists, in the future, miniature drones may appear that will buzz and fly like insects. Such devices may have many civil and military applications. In particular, they can be used for environmental monitoring and search and rescue operations. In an attempt to create miniature drones that fly like insects, engineers used gears and other complex mechanical devices to move the wings up and down. This gave the systems excessive complexity and mass, which affected the dynamic qualities. Inspired by bees and other insects, Bristol University's robotics ... >>

Mask with NFC tag 08.02.2022

Researchers at the University of Granada (UGR) in Spain have developed and tested a mask with an embedded NFC tag that alerts the wearer when carbon dioxide levels are exceeded by sending a special message to their smartphone. The FFP2 face mask detects the CO2 level in real time. The NFC module is connected to the mobile device and transmits the sensor readings to the application. The invention should help users to change the mask in time, or at least ventilate it from time to time. This will reduce the risk of adverse health effects from long-term CO2 exposure. "The system we propose is based on inserting a flexible tag into a standard FFP2 mask. The tag includes an innovative opto-chemical CO2 sensor and the necessary electronics for processing readings. The sensor and circuitry are made from a lightweight, flexible polymer material, forming the so-called "sensor label" that does not cause discomfort to the user," noted the ... >>

Recycled Solar Cell 08.02.2022

Invisible QR codes 06.02.2022

A group of scientists from the Massachusetts Institute of Technology (MIT), together with Facebook specialists, have developed a special system for marking objects - QR codes are not visible to the naked eye. The technology is called InfraredTags. InfraredTags creates barcodes and QR codes visible with infrared radiation. Marks are applied with a special plastic material for 3D printers in two ways. The first way to apply a mark is to alternate the thickness of the plastic when printing. The second way is to use transparent and opaque plastic in the infrared range. The second option is preferable, since the two plastic options are more contrasting and easier to read. To read the new tags, you need an inexpensive infrared camera. In the future, such tags can be used for various purposes - for example, to manage the infrastructure of a "smart" home from a phone or when buying goods in stores. ... >>

If the creation of a global network of atomic clocks is ultimately successful, it will give scientists a highly accurate tool to test some of the fundamental laws of physics, to study dark matter, to create high-precision systems ... >>

quantum apocalypse 05.02.2022

Breaking today's most complex encryption would take virtually forever, but experts warn that with the advent of quantum computers, this process could be reduced to a few seconds. Such technologies will lead humanity down a potentially dangerous path if they fall into the wrong hands. "Everything we do online today," says Harry Owen, director of strategy at PostQuantum, "from online shopping and banking to social media interactions, everything we do is encrypted." But quantum computers could allow attackers to "cleanse users' bank accounts by completely disabling complex security systems," warns Owen. Ilyas Khan, chief executive of Quantinuum, agrees with his colleague and calls encryption-cracking quantum computers "a threat to our way of life." And while the quantum apocalypse is probably many years away (if it ever happens), governments ... >>

Polyethylene liquid fuel 04.02.2022

Polyethylene is the most common plastic in the world. More than 100 tons are produced every year. The problem is that it is an incredibly inert material that does not react with almost anything, and therefore does not decompose under natural conditions. Zheng Huan, a chemist at the Chinese Academy of Sciences, was able to decompose polyethylene at 150 degrees Celsius by adding an organometallic catalyst, a small, commercially available organic molecule containing iridium. The catalyst weakens the bonds responsible for the strong structure of polyethylene, accelerating its decomposition and turning it into a liquid product. "The resulting products are much cleaner than conventional incineration products," Huang says, adding that the reaction is easier to control and the liquid can be used as a fuel. So far, the process has been demonstrated on small samples of plastic bags, bottles, and food packaging. Scientists now face two problems ... >>

Artificial muscle based on natural proteins 02.02.2022

Researchers from the University of Freiburg (Germany) have developed an artificial muscle based solely on natural proteins. Muscle contractions can be controlled by changes in the acidity of the environment and temperature. The material the scientists used is based on elastin, a natural fibrous protein also found in humans that gives elasticity to the skin and blood vessels. Researchers have developed two elastin-like proteins, one of which responds to fluctuations in acidity (pH) and the other to changes in temperature. The scientists combined the two proteins using photochemical cross-linking to form a bilayer material. So, in response to changes in the pH level in the aquatic environment where the material was placed, or temperature, the artificial muscle was able to contract rhythmically. In the case of temperature changes, the chemical reaction started at about 20 degrees Celsius. In this case, it was possible to program certain states of the muscle and with ... >>

Fish talk too 31.01.2022

Scientists from Cornell University (USA) have shown that fish communicate with sounds much more often than is commonly believed. And some species have been using this mode of communication for at least 155 million years. The authors examined a group of ray-finned fish and found 175 families among them, including two-thirds of the species that can communicate using sounds. After studying the family tree of fish, the authors of the study found that sound in fish communication was so important that this way of communication has evolved at least 33 times over millions of years. What are the fish talking about? With the help of sounds, they either try to attract a partner, protect a food source or territory, or let others know where they are. In their work, scientists used three sources of information: existing records and scientific articles describing the sounds of fish; fish anatomy data to find out if they have the necessary tools to create sounds: certain bones, an air bladder, and muscles specific to  ... >>

Portable atomic clock 31.01.2022

The Defense Advanced Research Projects Agency (DARPA) of the US Department of Defense announced the search for partners to create a portable optical atomic clock. They will have to be a hundred times better than today's most accurate portable watches. Today, atomic clocks are the most accurate way to measure time. Their principle of operation is based on the fact that each atom can emit and absorb photons only with certain frequencies - resonant for it. Atomic clocks are microwave and optical. The former are used, among other things, in GPS satellites, the data of which the military uses in many operations. The microwave atomic clock is based on a microwave resonator tuned to the transition frequency in the atom. They allow you to measure time in seconds with an accuracy of 16 decimal places. Their accuracy is limited by the ability to measure and control deviations of tens of microhertz in the desired resonant frequency. Optical atomic clocks use transitions in ... >>

Super flexible and fire resistant wood 29.01.2022

Chinese scientists have made a breakthrough in the creation of wood composites. They invented a technology that makes wood flexible while protecting it from the effects of fire and fungus. Chinese researchers took samples of tropical balsa wood up to five millimeters thick. Then they were placed in a special alkaline solution at a certain temperature for 12 hours. After that, the wood samples were filled with a new sample hydrogel. It was he who led to the fact that the material did not get wet, protected from ignition in an open fire and at the same time had excellent flexibility. According to Chinese scientists, a tree treated in this way can bend at a temperature of minus 50 degrees Celsius. And mold does not appear on it even if you leave such material in a room with a humidity of 90% for two and a half months. ... >>

Harm of gas stoves 29.01.2022

Leaking methane from stoves in US homes has the same climate impact as about 500 gasoline-powered cars, researchers estimate, and stoves can expose people to pollutants that cause respiratory illness. Natural gas stoves emit methane, a potent greenhouse gas, as well as other pollutants through leaks and incomplete combustion.

A new tool for modeling configurations and states of solid structures will show you how to get around all the problems. The microstructure of materials and solid electrolyte in particular has a strong influence on ion transport. The number of battery cycles and their current characteristics depend on this. At the same time, the microstructure can be influenced by using certain processing methods for its formation. The range of possibilities here is endless, which cannot be said about the time or resources for experiments. Will speed up ... >>

Electromechanical bandage 28.01.2022

Scientists from the China University of Electronic Science and Technology and Wuhan University have presented a dressing that affects the wound by mechanical force and electric shock, changing its microenvironment in such a way as to promote healing. The dressing consists of four layers. The lower one is an antibacterial PTFE polymer material that generates an electrostatic field on contact with a wound that penetrates up to 10 millimeters deep and kills bacteria (at least E. coli) with over 99,9 percent efficiency. It is coated with a layer of soft Ecoflex silicone for flexibility. Then there is a layer of shape memory alloy metamaterial, designed to contract when heated by the skin and mechanically connect the edges of the wound and direct the electric field. Finally, the fourth is another layer of silicone material. Despite the layering, the dressing turned out to be very thin - the entire "sandwich" does not exceed 0 millimeters in thickness. Scientists have developed two versions of ... >>

The strongest glue 27.01.2022

American researchers have created the strongest adhesive that can be used in the aerospace, automotive and construction industries. Scientists have studied the chemical structure of ordinary plastic and turned it into a reusable adhesive with unique properties. As a starting point in the production of the substance, experts used polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene (an important thermoplastic elastomer that behaves like rubber without being cured). The source for the manufacture of the most durable adhesive was a rubber-like polymer, which is used in toothbrushes, car steering wheel braid. But the glue was endowed with amazing and powerful properties by changing the chemical structure. The result was achieved through a process known as dynamic crosslinking, which allows normally incompatible materials to be joined. Scientists noted that a few drops of the created substance can hold about 136 kilograms of cargo on weight, and the new glue does not lose weight. ... >>

The cat's brain shrinks 27.01.2022

Scientists at the University of Vienna (Austria) and the National Museum of Scotland have found that the brain size of domestic cats is smaller than that of their African ancestors. It is known that the domestication of animals by humans leads to a decrease in the brain, which is observed in dogs, sheep and rabbits. In the new study, researchers measured the skull volume of a large number of domestic cat breeds to come up with an average. The same has been done with wild African cats, which are the ancestors of today's Felis domestica. The results confirmed that the brains of domestic cats are much smaller than those of their ancestors. To show that the decrease in brain size is due to domestication, the researchers compared the volume of the skull in European wild cats and their hybrids with domestic cats. In hybrids, the sizes occupied intermediate values ​​between wild and domestic species. Previous studies have shown that the reason for the decrease in brain size in pets is due to a decrease in the number of neural crest cells, which ... >>

Drone chasing pigeons 26.01.2022

A group of specialists from Switzerland has developed an automated system that scares away birds using drones without causing them any harm. Scientists from Switzerland have created a special system that scares away pigeons and drives them off the roofs. Birds too often shit not only on roofs, but also on cultural monuments. Experts installed a camera on the roof, which is set to recognize pigeons. She also calculates their coordinates. Then a drone is sent to this area, which makes a noise that scares away the birds. Ornithologists have already analyzed the behavior of pigeons. As it turns out, they spend much less time on rooftops if the system described above is running in standard mode. Scientists said that pigeon droppings not only spoil the appearance of buildings and cultural monuments, but can also carry a large number of diseases and parasites. ... >>

Hubble's Cosmological Stress Paradox Explained 26.01.2022

Scientists at the National Astronomical Observatory of the Chinese Academy of Sciences have proposed an explanation for the so-called Hubble voltage, that is, the paradox that the rate of expansion of the universe, measured locally, is greater than that indicated by observations of the microwave background. According to the hypothesis that forms the basis of standard cosmology, the universe is isotropic and uniform over large distances. However, observations reveal significant deviations from isotropy: for example, the distribution of matter in one direction is greater than in the other. In addition, the Hubble constant, indicating the expansion rate of the universe, also demonstrates the difference between local and global scales. The researchers believe that the observed deviations from isotropy can be explained by the existence of giant cosmic disturbances whose wavelength exceeds the size of the cosmological horizon - the maximum distance that light could travel since the beginning of the universe. These ... >>

Identification of birds by singing 25.01.2022

Birds have long been used by environmentalists to study food chains, biodiversity, and the healthy cycle of forests. Experts analyze records made in the forest for a certain period of time and determine which species of birds are present on them. Google has simplified this process with its new neural network. The first attempts of neural networks to analyze sounds faced a number of difficulties. At the time of morning birdsong, when they are most active, trills of many species can often be heard at the same time. In this case, the accuracy of the algorithm is significantly reduced. The sounds of wind, thunderstorms, rain and even insects further complicate the work of artificial intelligence. Google managed to solve these problems by applying the uncontrolled sound separation (MixIT) algorithm. It allows you to split one audio file into several isolated parts. Each of them contains the singing of one bird, which helps the neural network to further clearly determine its type. To improve the recognition process, random filtering was applied. ... >>

Resurrection of mammoths 25.01.2022

An American geneticist plans to bring back to life woolly mammoths, which became extinct about 10 years ago. He plans to transfer their genes to Asian elephants in order to save them from extinction. American researcher George Church and his colleagues from Harvard Medical School in Boston are going to "resurrect" the DNA of ancient mammoths in order to save Asian elephants. They will pass these genes on to living elephants so they can better resist the cold. As Church said, a new species of elephants will be able to live in arctic conditions. He is confident that the new elephants will be able to trample the Earth and prevent trees from growing quickly. They will also prevent the release of gases that are now lurking under the melting glaciers of the Arctic. However, according to Christopher Gingell of the University of Melbourne, it is not yet known exactly what these new Arctic elephants will be. Their behavior can be completely unpredictable. ... >>

Beam splitter roof for solar greenhouse 22.01.2022

Chinese researchers have developed a new type of beam-splitting greenhouse roof that can transmit visible light and convert near-infrared light into electricity. A team of researchers from the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences has developed this new greenhouse cover structure based on the use of solar spectrum splitting. Visible light with a wavelength of 400 nanometers (nm) to 780 nm is critical for triggering the photosynthesis process in greenhouse plants, but near infrared light with a wavelength of 780 to 2500 nm has little effect on plant growth and can cause the greenhouse to overheat. Tests by the research team have shown that the new solar roof can transmit visible light with an all-day penetration rate of 40%. And at the same time convert the near infrared light into electricity, ensuring the normal growth of greenhouse ... >>

Artificial moon for experiments with gravity 21.01.2022

Scientists from China have built a research center that will create a model of a low gravity environment using the effects of magnetism. The scientific laboratory, which is scheduled to open this year, will use powerful magnetic fields. The design is a vacuum chamber with a diameter of 60 cm, in which gravity can be made to "disappear". This decision was inspired by an experiment in which magnets were used to make a frog levitate. According to geotechnical engineer Li Ruilin of the China University of Mines and Technology, the chamber will be filled with rocks and dust to simulate the lunar surface - it is "the first of its kind" in the world and can simulate reduced gravity conditions "for as long as it's necessary". Scientists intend to use the center to test technologies in low gravity environments before they are sent to the moon, where gravity is approximately ... >>

People with no sense of smell can also smell. 21.01.2022

Scientists have found that people who lack olfactory bulbs can also smell. Perhaps alternative centers of smell are being formed in their brains. The ability to perceive smells depends on how well the olfactory information transmission system works - from sensory neurons in the nose through the olfactory nerves to the olfactory bulbs in the brain. Activation of small nerve structures within the olfactory bulbs, called glomeruli, causes the sensation of smell. Until recently, it was believed that people who, due to congenital pathology, lack olfactory bulbs, suffer from anosmia - they cannot smell. Scientists led by Noam Sobel of the Weizmann Institute of Science in Israel found that people without olfactory bulbs can still detect and identify the same odors as everyone else. Researchers first stumbled upon two women who could smell despite not having a sense of smell ... >>

ICE cars and hybrids catch fire more often than electric cars 20.01.2022

As the popularity of electric vehicles rises, some are raising concerns about their safety amid news that some new-energy vehicles are self-igniting. However, Auto Insurance EZ recently analyzed data from the US Bureau of Transportation Statistics, the National Transportation Commission, and the official vehicle recall website and found that hybrids have the highest relative fire rate, followed by internal combustion engine (ICE)-only vehicles, and then there are electric cars. In the United States, on average per 100 vehicles sold, hybrid models "lead" in fire frequency (000 units), second place is occupied by vehicles equipped only with internal combustion engines (3 vehicles), and electric vehicles are very far away, in third place, with the result is only 474 cars. ... >>

Waves of sand obey the laws of mathematics 19.01.2022

Sand waves with a wavelength of 30 centimeters to several meters are known as mega ripples: they are in size between the usual beach ripples and full-fledged dunes. In addition to their size, a key characteristic of megaripples is the arrangement of grains - large particles are always on top of small ones. This mixture is never the same, just like the winds that blow across the sand to create ripples. However, an international team of scientists has discovered an amazing mathematical feature of the megaripple: the ratio of the diameter of the largest particles to the diameter of the smallest is always constant. Specimens have been studied from megaripple fields in Israel, China, Namibia, India, Jordan, Antarctica, and New Mexico in the United States. Further analysis was supplemented by observations made on Mars and the results of an experiment in a laboratory wind tunnel. "An extensive collection of terrestrial and extraterrestrial data, covering a wide range of geographical sources and environmental conditions, confirms the accuracy and reliability of this ... >>

DNA antenna 18.01.2022

Researchers at the University of Montreal in Canada have used deoxyribose nucleic acid - or DNA, the building blocks of our genetic material - to create the world's smallest antenna. It is designed to track the movement of proteins within the cell, the university said in a press release. It is reported that the "antenna" formed from DNA can receive and receive signals, but it uses light to do this. Scientists at the University of Montreal used a tiny antenna to track the movement of a squirrel by sending it a light signal. Depending on the movement of the protein molecule, the antenna transmitted signals of different colors. At the same time, the response signal could be recorded using a spectrofluorimeter - a device that is commonly used in various scientific laboratories around the world. Scott Harron, one of the study's authors who created the tiny antenna, noted in a press release that the chemistry of DNA is actually very simple and easy to program. DNA function ... >>

Antimatter falls down like normal matter 17.01.2022

Physicists from the European Organization for Nuclear Research CERN conducted a series of studies and determined that antimatter interacts with gravity, like ordinary matter, and falls in the "correct" direction, i.e. way down. Undoubtedly, this seems like a completely obvious thing, however, scientists for quite a long time could neither confirm nor deny this fact, and only the last experiment allowed them to give a more or less accurate answer, but even then with some assumptions. Antimatter is an exact copy of matter with only one important difference - the presence of an opposite electrical charge. And this difference has some serious consequences, every time a particle of ordinary matter and antimatter collide in space, they mutually destroy each other, turning into pure energy. Fortunately for all of us and the world around us, which consists of ordinary matter, antimatter is a rarity in the Universe. And this is one of the main fund ... >>

Dogs sense wrong physics 17.01.2022

Some simple physical patterns we feel intuitively from a very young age. For example, even small children know that if you drop a cup from your hands, it will fall down - and they will be very surprised if the cup suddenly starts to slowly take off. Intuitive ideas about the physics of the world around us are not only in humans, but, for example, in chimpanzees and dogs. The study was conducted by employees of the University of Vienna. They chose fourteen dogs, who were first taught to sit in one position with their heads resting on a special pillow. In this position, it was convenient to follow the pupils of the dogs, which testified to their emotions. Then a screen was placed in front of the dogs, and a video was shown on the screen: two balls rolling towards each other. The balls collided, and then one stopped, and the second rolled back - all in accordance with ordinary mechanics. After the dogs had seen enough of the colliding marbles, they were shown a second video in which the first marble stopped before ... >>

Capturing methane from the air with zeolites 14.01.2022

Researchers at the Massachusetts Institute of Technology (MIT) have found that zeolites - porous mineral structures often used as commercial adsorbents - are able to absorb and recycle methane (CH4) from the air. This effect is manifested when they are processed with copper. The scientists' work is published in ACS Environment Au. In a lab experiment, experts placed zeolite particles in a reaction tube and passed air containing varying concentrations of methane through it. Gas levels ranged from 2 ppm to 2%. And the reaction tube was heated to various temperatures. When heated to 310 degrees Celsius, the zeolite was able to capture and convert 2% of the methane into carbon dioxide (CO100). The process is possible even at low CH4 concentrations and much lower temperatures than are required for other methane capture methods. At first glance, turning one greenhouse gas into another is not ideal. But the researchers calculated that the conversion ... >>

Revealed the secret of longevity of turtles 13.01.2022

Scientists for many years could not uncover the secret of the longevity of giant tortoises in Ecuador - as a rule, their life expectancy is more than 100 years. However, the mystery has recently been solved. Giant tortoises have extra copies of genes involved in what is known as apoptosis, according to a study by scientists at the University at Buffalo in the US. This is a cell self-destruction process that protects turtles from the damaging effects of aging, including cancer. Laboratory tests conducted on the giant tortoises of the Galapagos Islands confirmed the presence of a similar defense mechanism in these animals. As the researchers note, when exposed to such stress, the cells of the Galapagos tortoise self-destruct much more easily than the cells of other species of turtles. What cells are destroyed before they have a chance to create a tumor. This helps prevent the development of cancer. "These results are of great interest ... >>

The danger of urban smog 11.01.2022

Major cities around the world are affected by smog, and it takes lives. According to scientists, in 2019 alone, air pollution led to 1,8 million deaths worldwide. Simulations carried out by scientists showed that 86% of the inhabitants of large cities - and this is approximately 2,6 billion people - are exposed to fine particulate matter at levels that exceed the recommendations of the World Health Organization (WHO). PM2,5 - fine particulate matter 2,5 micrometers in diameter or less - is a leading environmental risk factor for disease. Their inhalation increases the risk of premature death from cardiovascular and respiratory diseases, lung cancer and lower respiratory tract infections. It found that the population-weighted average concentration of PM2,5 in all urban areas of the world in 2019 was 35 micrograms per cubic meter, equivalent to seven times the WHO recommendations for 2021. In 2019, every 61 out of 100 deaths in ... >>

Egg white from microbes 11.01.2022

Egg white is one of the most important and common additives in the food industry. But to obtain it, you need to breed, grow and care for a large number of chickens. This means that a significant amount of water is being used, agricultural land is expanding, threatening natural environments, and a lot of greenhouse gases are being released. And given that the world's population is growing, we can expect an increase in chicken farming, which will have an even greater negative impact on the environment. In addition to environmental concerns, intensive poultry farming threatens more frequent outbreaks of infections that can be transmitted from poultry to humans, such as bird flu. Giving up egg white is not an option, so science is working to develop alternatives. It can be the use of genetically modified microbes, which forced the production of chicken egg protein - ovalbumin - by introducing the corresponding gene into the genome. For example, this has already been done ... >>

Laser drones against pests 10.01.2022

According to Japanese officials, up to 16% of raw materials for food production in modern conditions are lost due to the impact of pests. At the same time, by the middle of the century, the demand for food will increase by 70% due to population growth, and global warming will only create more favorable conditions for the reproduction of pests. Experts suggest using artificial intelligence-controlled laser weapons to combat them. So far, Japanese developers from the NARO research association do not even have a prototype laser installation for combating harmful insects, but they expect to conduct field tests next year. The principle of insect control is quite simple: a stereoscopic camera will detect them, and an artificial intelligence system will predict the flight path of pests and shoot them down with a laser pulse, firing with a little lead. The fact is that in 0,03 seconds, which the system needs to aim, moto ... >>

Artificial lung tissue following the example of light lizards 09.01.2022

Unlike human lungs with their complex tree structure, light brown anole lizards develop much more simply. And they can become a suitable model for creating artificial lungs, developed by scientists at Princeton University (USA). In birds and mammals, lungs develop into very complex structures due to endless branching and complex biochemical signaling. The lungs of the brown anole are formed in a simpler way: as if a soft ball is squeezed out of the net, as in an ordinary anti-stress toy. The lizard's lung begins to develop as a hollow, elongated membrane surrounded by a uniform layer of smooth muscle. During development, the cells of the lungs secrete fluid, and in doing so, the inner membrane slowly swells and thins like a balloon. This puts pressure on the smooth muscle, causing it to contract and spread into fiber bundles, which eventually form a honeycomb-shaped mesh. Fluid pressure continues ... >>

Fusion reactor five times brighter than the sun 09.01.2022

A fusion reactor in China has set a record for sustained high temperatures, reaching 70 million degrees Celsius. Thus, the plasma in the installation was heated five times stronger than the Sun.

Invoxia has announced a new smart collar that has the functionality of smartwatches and fitness trackers. Invoxia has worked with certified veterinary cardiologists to develop neural network-based artificial intelligence that uses miniaturized radar sensors. These radars are perfect as they are able to take readings no matter how furry your dog is. Another plus is that the collar can sit more loosely around the dog's neck. The same cannot be said for the smartwatches and fitness trackers that people use, which require a tighter fit and good skin contact to get accurate heart rate readings. The Invoxia collar is different because it combines a traditional GPS tracker with a non-invasive way to monitor vital signs. It is compatible with Bluetooth, Wi-Fi, GPS and LTE-M, and comes with escape warnings and a built-in horn. While the Invoxia collar is only for ... >>

Electric car Mercedes-Benz VISION EQXX 07.01.2022

By the end of the decade, the German automaker Mercedes-Benz intends to completely abandon the production of new models of passenger cars with internal combustion engines, so the brand is showing its potential in the field of electrification at the first opportunity right now. Another concept impresses with a power reserve of more than 1000 km and record-breaking aerodynamics. The VISION EQXX Concept is the fruit of further efforts by Mercedes-Benz to improve the efficiency of electric vehicles. The efficiency of the power plant, for example, was brought up to 95% - only five percent of the energy stored in the traction battery is lost when torque is transmitted to the wheels. Experts from the Mercedes-Benz racing team took an active part in the creation of the prototype, and the traction battery received an impressive charge storage density of about 400 Wh / l. As a result, it provides a capacity of just under 100 kWh, with half the size and 30% reduced weight compared to existing analogues. At the same time, the accumulator ... >>

Adult elephants calm the youth 07.01.2022

Elephants seem to us smart and kind, but sometimes they find something on them, and they become violent and aggressive, attacking cars, motorcycles and bicycles, animals, people. Researchers at the University of Exeter have found that the aggressiveness of elephants - at least young ones - noticeably weakens when older elephants are next to them. Researchers observed elephants in Botswana's Makgadikgadi National Park for three years. Among almost three hundred males there were elephants of various ages: teenagers (10-15 years old), older teenagers (16-20 years old), adults (21-25 years old) and elderly (over 26 years old). Elephants could quarrel with each other, but it is curious that adolescents more often attacked some foreign objects and other animals (in particular, livestock) when there were no elders nearby. At the same time, young elephants were not only more aggressive, but also more shy, which is understandable: aggressiveness is associated with fear, both in animals and in people. If in the group of elephants there were not only ... >>

L'Oreal Colorsonic device for hair coloring 06.01.2022

Cosmetic company L'Oreal has introduced a device for quick and comfortable hair coloring at home. Colorsonic looks like a hair dryer brush or flat iron. But in its lower part there is a cartridge containing the desired mixture for staining. Using the device, the user can choose one of 40 colors, after which the gadget will mix the necessary components. Next, you just need to start combing your hair from roots to ends. At this time, the device, through special nozzles that move more than 300 times per minute at a certain angle, will evenly distribute the prepared paint and developer. However, those with darker hair will still need to pre-bleach their hair. The device consumes less ink and allows you to reduce the consumption of disposable materials. Colorsonic's recyclable cartridges contain less plastic than regular ink cartridges. And unused pigments and developer are stored separately. The Coloright system from L'Oreal is already ... >>

Electronic noses for livestock farms 06.01.2022

A research team from the Department of Educational Technology, Institute of Livestock Environmental Management, Korea, has developed a livestock odor monitoring system using information and communication technology and an ammonia sensor. With the development of large intensive livestock farms, interest in odor control has increased significantly. Farm animal odors contain many compounds such as ammonia, hydrogen sulfide, volatile fatty acids and p-cresol. Ammonia is the most common smelling compound. Due to the rather frequent cases of complaints about odors from livestock, especially near large farms, research on monitoring this parameter is expanding. Electronic nose (e-nose) systems have recently emerged as a technology and are now undergoing quantitative validation studies in poultry and pig farms, mainly. The electronic nose is an alternative technology that provides benefits such as quantitative analysis, b ... >>

It is best to sleep on your side 04.01.2022

Employees of the University of Technology from Norway proved that people who sleep on their side have a healthy sleep. Norwegian scientists conducted a study of the positions of sleeping people together with colleagues from Denmark. It turned out that those who sleep on their side have a better sleep than those who prefer to fall asleep in other positions. Sleeping on your side is a guarantee of long life for women who care about their health. People who sleep on their side have fewer problems with curvature of the spine. They are healthier than those who prefer to fall asleep in other positions. Scientists have also determined that for a woman, sleeping on her side is even more beneficial. They believe that this is the key to female longevity. But researchers note that sleeping on the left side is contraindicated for those who have had a heart attack or have diseases of the cardiovascular system. Also, sleeping in a similar position gets some load on the liver. And pregnant women, on the contrary, are strongly recommended to sleep on their left side, h ... >>

Rice Based Heat Resistant Film 03.01.2022

Researchers at the University of Science and Technology of China (USTC), inspired by the manufacturing process and structure of rice paper, have developed a high-performance transparent folding film. Rice paper, or Chinese painting paper, is made from bark and straw and undergoes hundreds of manufacturing processes during the manufacturing process. By studying the structure of rice paper, USTC researchers found that it contains a large amount of nano- and microfibers, which gives it the advantages of high strength and flexibility. Thanks to these properties, after complete folding, there are no folds that can damage the film. In addition, after folding, it can return to its original shape. Compared with conventional petroleum-based PE film, this film has excellent heat resistance, and even at 250 degrees Celsius, there is no obvious change. These mechanical, thermodynamic and optical characteristics make ... >>

Nanowire instead of a hard drive 03.01.2022

An international team of scientists led by the Cambridge University's Cavendish Laboratory has used cutting-edge 3D printing techniques to create double magnetic spirals that serve as information carriers. The researchers found that they create nanometer-scale topological textures in a magnetic field. Previously, no one has recorded such a phenomenon, and the discoverers believe that the twisted nanowire can become the "ancestor" of the next generation of magnetic devices. Magnets are widely used in storage devices and computing systems. The disadvantage of the latter is that the magnetization points in them are two-dimensional structures. But the nanowire architecture is three-dimensional, which allows a higher recording density, as well as changing the magnetic properties of the device and significantly expanding its functionality. Until now, this idea has been very difficult to implement, because scientists have not had the ability to create three-dimensional ma ... >>

Transfer of solar energy from orbit to Earth 02.01.2022

The US Air Force Research Laboratory (AFRL) and the military-industrial company Northrop Grumman conducted the first demonstration of key industrial-scale power generation equipment in Earth orbit. In 2018, AFRL awarded Northrop Grumman a $100 million contract to develop key components of a prototype space power grid. The company's engineers have begun to create sheet panels, which should be the main elements of the massive Arachne program, which aims to ensure uninterrupted power transmission to military bases located in remote regions. To do this, solar panels in orbit will convert solar energy into radio frequencies and transmit to ground stations. There it will be captured and converted back into electricity by special rectifying antennas, or rectens. Sandwich solar panels are a key component of this technology, since their presence in the level ... >>

Electricity from sea lettuce 02.01.2022

Researchers at the Technion - the Israel Institute of Technology - have developed a new method to generate electrical current directly from seaweed in an environmentally friendly and efficient way. The idea, which first occurred to Technion doctoral student Yaniv Schlosberg while swimming on the beach, was brought to fruition by a team of researchers from three Technion faculties that are members of the Technion's Large Energy Program (GTEP), along with a researcher from the Israel Institute of Oceanography and Limnology in Haifa (IOLR). ). As is known, the combustion of fossil fuels leads to the emission of greenhouse gases and other pollutants that affect climate change, and various forms of environmental pollution occur at all stages of production, transportation, processing and consumption of these fuels. The climate crisis and environmental issues are driving the research and search for alternative, clean and renewable energy sources. One ... >>

Water freezing point record broken 01.01.2022

Knowing how and why water turns to ice is essential to understanding a wide range of natural processes. Climate fluctuations, cloud dynamics and the water cycle are affected by the transformation of water and ice, as are animals living in freezing conditions. Tree frogs, for example, survive the winter on land by allowing their bodies to freeze. This allows them to emerge from hibernation faster than species that hibernate deep underwater without freezing. But ice crystals can rupture cell membranes, so animals that use this technique need to find a way to prevent ice from forming in their cells and tissues. A better understanding of how water freezes can lead to a better understanding of these extreme species. Although the rule of thumb is that water freezes at 0 degrees Celsius, water can remain liquid in the low temperature range under certain conditions. Until now, it was believed that this range stopped at minus 38 degrees Celsius. ... >>

Christmas ball with real snow generation 01.01.2022

Canadian inventor Sean Hodgins has created a Christmas ball that generates snow. Usually such balls simply contain plastic particles that mimic snow flakes. The new device turned out to be curious, but energy-intensive. Hodgins needed a power supply, a cooling fan, heatsinks, and a PC CPU cooler. He carved a tiny snowman out of aluminum so that the snow could grow somewhere. A couple of two watt resistors were also added to evaporate the water. In addition, negative temperatures had to be provided in the ball. To recreate winter in the balloon, Hodgins installed several thermoelectric coolers stacked on top of each other. They managed to create with their help a temperature difference of 60 degrees Celsius, which was more than enough for water vapor to condense and freeze on an aluminum snowman. So he was covered in snow. ... >>

Subcutaneous chips with COVID-passport 31.12.2021

Several thousand Swedes have implanted implants under their skin in recent years, eliminating the need to constantly carry public transport tickets, a bank card, an electronic key or a business card. Recently, DSruptive Subdermals started using the chips as a COVID passport. This was reported by the agency AFP. "A chip implant costs 100 euros. If you want to buy a more advanced version, for example, for tracking health indicators, it will probably cost twice as much. But a chip implant lasts 20-40 years," said Hannes Sjoblad, Managing Director DSruptive Subdermals. Many "consider chips a scary technology," he says, but they should be treated as mere identification tags. "They don't have a battery, they can't transmit on their own, they can't determine your location," Sjoblad said. The chip consists of certified biocompatible glass, high brightness lead-free LED, ultra-thin circuit board with ... >>

Soundbar LG S95QR 31.12.2021

LG has announced the S95QR soundbar with 9.1.5 sound configuration, support for Dolby Atmos and DTS:X and an interesting solution: the center channel is directed upwards so that the voice while watching a movie is reflected from the ceiling and clearly distinguished by the ear. The kit also comes with a wireless subwoofer and a pair of additional rear speakers. The standard center channel and upward-firing speaker carry the same signal, and this solution improves the clarity of dialogue; similarly, one signal is carried by the corresponding side speakers of the soundbar and complete rear speakers - this configuration positively affects the depth of the immersive effect. The timing and delays of the speaker are adjusted automatically using the AI ​​Room Calibration function. The total output power of the audio system is 810 watts. The notable drawback of the soundbar was its inability to pass-through HDR video in 4K resolution at 120Hz. This means that owners of Xbox Series X or PS5, as well as 4K TVs ... >>

Prototype flexible pneumatic tentacles 30.12.2021

Chinese researchers from Shanghai Zhao Tong University borrowed the idea of ​​a multi-segment soft manipulator from octopuses. Robotentacles have been developed, which are elastomeric structures with a pneumatic drive. The tentacle-like arms are propelled by air pressure and consist of a series of interconnected pneumatically inflated internal chambers. One side of the tentacle is flexible, the other is more rigid. An increase in air pressure in the chambers leads to a bending of the structure in the direction of greater rigidity. "We developed the soft arms using a mathematical model that can follow a defined XNUMXD spatial trajectory. Our soft arm consists of several segments, each with its own actuation mode - twisting, bending or spiraling," said Dong Wang, author of the study. . The main achievement of the presented work is the development of a mathematical methodology that can automatically ... >>

The lightest isotope of magnesium 28.12.2021

In collaboration with an international team of researchers, Michigan State University has created the world's lightest version of magnesium. The record-breaking isotope magnesium-18 is produced at the National Superconducting Cyclone Laboratory (NSCL) and is so unstable that it decays before scientists can measure it directly or detect it in nature. Therefore, using a particle accelerator, physicists created it in the laboratory in an attempt to understand how atoms are arranged and where the elements of the universe come from. This will help predict what happens in extreme space environments that may never be directly reproduced or measured from Earth. All magnesium atoms have 12 protons inside the nucleus. Previously, the lightest version of magnesium had 7 neutrons, giving a total of 19 protons and neutrons. To get magnesium-18, which is one neutron lighter, the team took magnesium-24. The cyclotron accelerated a beam of magnesium-24 nuclei to about half the speed of light and directed it at a target: a metal ... >>

Cow toilet 28.12.2021

An international group of zoologists decided to educate calves about hygiene. To do this, they rewarded each calf after visiting the toilet, and they soon got used to defecate in the place designated for this. Urine contains a lot of nitrogen. This nitrogen, once in the soil, is to the taste of microorganisms. As a result, the processing of urine produces nitric oxide, the strongest greenhouse gas. Zoologists from the German Farm Animal Research Institute, together with Australian colleagues from the University of Auckland, decided to teach hygiene to calves. To do this, they rewarded each calf after visiting the toilet, and they soon got used to defecate in the place designated for this. “At first, we punished the calves by putting microphones in their ears, and they played an unpleasant sound if the calf ignored the toilet. It didn’t work and we had to act with affection,” explains animal psychologist Jan Langbein. Within a few weeks, 11 out of 16 experimental animals learned the rules of hygiene. Result ... >>

James Webb telescope launched into orbit 27.12.2021

NASA successfully launched the James Webb telescope. The telescope was jointly built by 17 countries, it took 25 years and 10 billion dollars. Webb is much larger, more complex and more powerful than the Hubble Space Telescope, which has been studying the skies from Earth orbit for more than 30 years. Another key difference between Hubble and Webb is that the old telescope was designed to be serviced by astronauts on spacewalks, having been repaired and upgraded 5 times between 1993 and 2009. But the Webb will be too far away for people to reach it. James Webb is the latest orbital infrared observatory to replace the Hubble telescope. The new telescope is XNUMX times more sensitive to wavelength than Hubble. Scientists believe that the device will be able to expand mankind's understanding of the Universe, as it is able to reveal the history of the formation of the first stars and galaxies, as well as to study black holes, dark matter and galaxies far from the solar planet in more depth. Obo ... >>

TV broadcasting smell and taste 27.12.2021

In Japan, Taste the TV was created, capable of transmitting not only a “picture”, but also smell and taste. True, for this the viewer will have to lick the screen. Designed by Professor Meiji Gomei Miyashita, the TV has 10 flavored liquid containers that are dispensed onto a sanitary film depending on the content currently being broadcast. Professor Miyashita believes that his invention will be relevant in the era of coronavirus and the need to avoid unnecessary contacts - the TV will help you try an unknown dish before the owner goes to a restaurant or orders home delivery.

Transistor that replaces entire logic circuits 26.12.2021

Scientists have taken a step in an interesting direction in the production of semiconductors - they have developed a dynamically programmable transistor, which alone can implement such multi-component logic as NOR, NAND and others. The proposed transistor fits easily into the existing production infrastructure and does not use exotic materials. A special benefit from its use is expected in the field of artificial intelligence. A conventional transistor consists of two electrodes for the current-carrying channel and another electrode for controlling the channel (gate). Gate control allows current to pass through the transistor or to turn it off. Almost all modern digital electronics is based on this principle. Researchers from the Technical University of Vienna (TU Wien) proposed adding two additional electrodes to the transistor structure and connecting them with the thinnest pure germanium (Ge) thread. And it brought success. Due to its electronic properties, germanium exhibits the effect ... >>

Solar panel-sandwich for direct transmission of energy from space to terrestrial receivers 25.12.2021

As part of Northrop Grumman's contract with the Pentagon, the first solar panel was created and tested to directly convert sunlight into a radio frequency energy beam and wirelessly transmit energy from space to terrestrial receivers. The experimental panel showed itself with high efficiency in laboratory conditions and became the first of its kind (about 1 m2 in area). There are four years left before testing in space. Northrop Grumman has awarded a contract worth over $100 million to the US Air Force Research Laboratory (AFRL) for the Space Solar Power Incremental Demonstrations and Research (SSPIDR) program.

The maximum daytime temperature rose to +8,3 degrees Celsius. For such high latitudes, given the cold season and the fact that the polar night reigns in Greenland now, this is a real anomaly! ... >>

Tsunami prediction 24.12.2021

Tsunamis are one of the most dangerous weather events, so any new solution that helps track big waves earlier is welcomed with open arms. Scientists from the University of Kyoto have previously noticed the magnetic field of a tsunami, but only now have they been able to confirm that it can be used to detect an impending danger. When large waves form in the ocean, an extremely strong magnetic field is created. It is its measurement that is intended to provide information about a possible tsunami, which, in theory, will help emergency services quickly inform people about the upcoming disaster. To confirm their hypothesis, scientists from the University of Kyoto decided to study two such disasters - the 2009 tsunami in Samoa (a small country in Oceania) and the tsunami that hit Chile in 2010. The study used data from measurements of seabed pressure and magnetic field that were recorded during the formation of large waves. Japanese scientists found a correlation ... >>

Glass that generates solar energy 24.12.2021

In Poland opened the world's first production of double-glazed windows capable of generating energy from the sun. Such double-glazed windows, like ordinary ones, are completely transparent and are able to provide houses and apartments with the necessary sound insulation. Double-glazed windows generate energy thanks to a special quantum coating of semiconductors invisible to the human eye, up to several nanometers in size. They are able to generate electricity from both natural and artificial lighting, while not heating the glass surface. The cost of one square meter of such glass is from 300 to 500 euros. In 2021, Europe reached a record level of solar energy production. However, according to climate research center Ember, solar panels still produce less electricity than coal-fired power plants in Europe, so in order to meet the goal of reducing greenhouse gas emissions by up to 55% by 2030, EU countries need to double number of suns ... >>

Virtual walking attachment 23.12.2021

Japanese engineers have introduced an addition to the virtual reality helmet - footrests with vibration motors that simulate the feeling of walking. The system itself selects the necessary vibration for 360-degree rollers, evaluating the trajectory of the camera. How to feel vibrations and steps in the snow, and a walk on the lawn, the scientists specified in an article published in the journal IEEE Access. Virtual walking systems can be divided into active and passive. Firstly, you will have to move your limbs on your own to walk in a virtual environment, and secondly, sensory stimuli and passive movements of the limbs or the whole body are used for this. The illusion of one's own movement can be created by a combination of auditory and tactile stimuli, as well as, for example, camera shake. You can also electrically stimulate the leg muscles or use vibration. The engineers of the Toyohashi Institute of Technology stopped at the last option and taught their VR stand to generate vibrations for panoramic videos, ... >>

Protocol for designing multidimensional states 23.12.2021

The inevitable presence of noise and shortcomings in the characteristics of experimental devices reduce the overall quality of generation of multidimensional states. To overcome these limitations, a team of researchers from Sapienza University of Rome, Queen's University of Belfast and the University of Palermo used an adaptive optimization protocol capable of generating arbitrary multidimensional states. The adaptive optimization protocol constructs arbitrary multidimensional states for solving quantum information problems that require finding optimal values ​​of experimental parameters in noisy conditions. The creation of multidimensional quantum states in quantum information protocols provides better performance in applications ranging from secure quantum communication to fault-tolerant quantum computing. A significant achievement would be the development of universal protocols capable of constructing arbitrary multidimensional quantum states. For this purpose, it was proposed and developed ... >>

Lifespan biomarker found 22.12.2021

American scientists have found that the rate of accumulation of genetic mutations can predict how many years a person will live. In women, this method also allows you to predict the period of fertility. It has long been known that DNA damage occurs constantly throughout life, but the body has repair mechanisms that prevent the accumulation of harmful mutations. Over time, these mechanisms become less efficient, so, for example, older parents tend to pass on more genetic mutations to their offspring through the germline - egg and sperm. Biologists from the University of Utah and the University of Louisville have suggested that the rate at which a person acquires DNA mutations can serve as a biomarker of aging and can predict lifespan even in young people, as well as fertility in women. The basis for the study was the data bank of the Center for the Study of Human Polymorphism - an international research genetic institute in Paris ... >>

Drones will automatically fly to the scene of the firefight 21.12.2021

Engineers from an Israeli company have presented a system of drones that automatically respond to shots. They help the police assess the situation on the spot. Israel has introduced a system that combines autonomous drones with technology for determining the location of shots. ShotSpotter will be used in over 120 cities in the US, South Africa and the Caribbean. She uses a network of microphones in the area to detect "loud, impulsive sounds". When such a sound is detected, its geographic origin can be determined by analyzing the millisecond difference in time during which it was recorded by different microphones - the closer the microphone was to the weapon, the earlier it recorded the sound of the shot. In doing so, a combination of AI software and live personnel is used to determine whether a sound is indeed a gunshot. In the current version of the system, devices are immediately sent to the scene of a shootout, and a police squad is sent there. ... >>

paper batteries 21.12.2021

Scientists at the Nanyang Technological University in Singapore (NTU Singapore) have developed paper-thin and fully biodegradable zinc batteries that could one day become an environmentally friendly power source option for flexible and wearable electronic systems. A square battery measuring 4x4 cm and only 0,4 mm thick can run a small electric fan for 45 minutes. Bending, twisting the battery, or even cutting off fragments of it did not lead to power outages. In our research, scientists have shown an easier and cheaper way to manufacture batteries, producing one large piece of battery that is cut into desired shapes and sizes without loss of efficiency. These features make paper batteries ideal for integration into flexible electronics. The manufacture of the battery begins with the reinforcement of cellulose paper with hydrogel, which fills the voids between the cellulose fibers. This forms ... >>

quantum spin liquid 20.12.2021

A new exotic state of matter, the possibility of whose existence was theoretically justified more than 50 years ago, was obtained in laboratory conditions for the first time in history. Created by researchers at Harvard University, this material is called quantum spin liquid, and its further study and use will create a number of new technologies that can have a great impact on the further development of quantum computing and communications. In order for any material to have magnetic properties, it is required that the rotation of the electrons of the atoms of this material be aligned in one direction. Slightly different types of magnetism can be observed when the rotation of electrons in a material alternates like checkerboard cells, however, such materials still have exotic magnetic properties due to the orderliness of the electron spins. In 1973, the American physicist Philip Anderson (Philip Anderson) put forward a hypothesis about the possibility of the existence ... >>

Artificial intelligence will distinguish the original painting from a fake 19.12.2021

Researchers at Case Western Reserve University have trained artificial intelligence to distinguish artists by style. The neural network can distinguish the true picture from the fake one. For the first time, scientists have used artificial intelligence to study the 3D topography of a painting. Prior to this, forms of analysis were based only on visible stylistic differences. Artificial intelligence will allow you to study the three-dimensional surface topography and find all the differences in the layers of paint. Case Western Reserve physics professor Kenneth Singer said: "3D topography is a new way for artificial intelligence to 'see' the picture. The AI ​​algorithm focuses on the smallest surface structures," said Case Western Reserve physics professor Kenneth Singer. Artificial intelligence was modeled on the human brain and nervous system. In 95% of cases, the neural network will be able to determine the artist who painted this or that picture. "We divided the picture into virtual sections ranging in size from a few mm to cm ... >>

Inspiration is born between sleep and wakefulness 18.12.2021

History knows many cases when inspiration came to great people in a dream, and these great ones sometimes even used special methods in order not to forget their sleepy insights. For example, Thomas Edison and Salvador Dali, thinking about some difficult creative task, lay down to take a nap, holding something heavy in their hands. When they started to fall asleep, the hand relaxed, the object fell to the floor and woke them up - and then it turned out that the solution to the creative problem was already in their head. Employees of the Sorbonne University decided to test this method and invited one hundred and three people for the experiment, who were also supposed to doze off with a heavy object in their hand. Before falling asleep, they were given a mathematical problem: several number sequences had to be continued by one more number, and in order to get this number, two mathematical rules had to be applied to the sequence. However, the solution to the problem could be easier if you notice that the required number is always the same as the second number ... >>

Digital apocalypse 18.12.2021

Experts warn that in a few years we will face a digital apocalypse associated with an exponential increase in the amount of data that, until recently, no one could have imagined even in the wildest forecasts. In this regard, scientists call to recognize digital content as the fifth state of matter, along with gas, liquid, plasma and solid. They argue that at some point humanity will accumulate so much digital data that the number of bits that make up this data will approach the number of atoms that make up the entire Earth (10 to the 50th power). To store and process this amount of information, humanity will require much more energy, in contrast to how much it currently produces. Hence the call of scientists to stop considering digital content solely as a virtual sequence of ones and zeros, and treat it as a specific physical quantity, that is, matter. It is estimated that humanity produces daily ... >>

Invisible system to protect bicycles from theft 17.12.2021

A sleeping bag that will keep astronauts sighted 17.12.2021

NASA researchers have developed a special sleeping bag that will help prevent visual impairment in space. A similar problem is faced by astronauts who are on the ISS for more than six months. The device helps relieve pressure in the brain - it creates a vacuum and pumps fluid from the head to the legs. The bag will help alleviate vision problems in space, something that every astronaut faces during long missions. The reason for this is the lack of gravity. During sleep, the fluid in the head does not go down due to gravity, but continues to put pressure on the eyeball. This reduces the quality of the astronauts' vision and deforms the back wall of the eye. Just three days of lying flat can change the shape of the eyeball, a new study has found. High-tech bags could be a possible solution that will save astronauts. According to NASA, more than half of the astronauts on the ISS suffer from vision problems. Scientists hope that sleeping bag will help to cope with it ... >>
