The brain is able to remember foreign words in a dream 19.06.2023

Recent studies by scientists at the University of Bern have confirmed an interesting feature of the brain: the ability to remember foreign words during sleep. The legend that sleep can promote more effective learning has received scientific support, although scientists remain skeptical of this claim. However, there is some evidence that the brain is able to process and store information received in certain phases of sleep. Researchers have focused on slow wave sleep, especially its first phase. At this point, the brain goes through short periods of activity and recession that last about 30 seconds. A team of scientists led by Flavio Schmidig has developed an algorithm that predicts the exact timing of the next peak and fall of brain waves based on electroencephalography data. This algorithm was used to perform experiments on 30 volunteers who slept in the lab and had their nose ... >>

A new state of matter: a crystal of bosons 19.06.2023

A group of physicists from the University of California at Santa Barbara have made a sensational discovery, revealing the secrets of a unique material created from bosons. Until now, the scientific community has focused on the study of fermions - subatomic particles responsible for the stability and interaction of matter. However, the latest breakthrough opens a new chapter in the study of the special properties of bosons and expands our knowledge in the field of elementary particle physics. By superimposing the lattices of diselenide and tungsten disulfide in a special twisted configuration known as a moiré pattern, the scientists created a highly ordered crystal of bosonic particles called excitons. This led to the emergence of a new state of matter, which was called the "bosonic correlated insulator". Bosons differ from fermions in their unique behavior. While fermions cannot occupy the same energy level, bosons easily share it, resulting in their special properties. Professor Ch ... >>

Headphones will warn of loss of consciousness 18.06.2023

Digital health startup STAT Health has developed innovative headphones that can track blood flow to the head and warn of fainting. This technological solution can be especially useful for people suffering from diseases associated with dizziness, and allows you to predict the deterioration of their health. According to STAT Health's CEO, Daniel Li, many physicians find it difficult to determine the cause of uncomfortable symptoms such as dizziness because there are no precise methods of measurement. However, with the help of new headphones, it becomes possible to confirm the presence of problems and collect reliable information about the condition of patients. It is important to note that these headphones are not a form of treatment, but rather serve as an information tool that allows people with serious medical conditions that cause dizziness and blackouts to monitor their health indicators. The device is small and fits in ... >>

Large-scale testing of the Einstein-Podolsky-Rosen paradox 18.06.2023

Scientists from the University of Basel in Switzerland have conducted a large-scale test of the Einstein-Podolsky-Rosen (EPR) paradox in quantum mechanics. The researchers used two entangled Bose-Einstein condensates of 700 atoms each and demonstrated that the EPR paradox persists even in the presence of a cloud of hundreds of atoms. Such an observation was the first of its kind where the EPR paradox was investigated in spatially separated multiparticle systems. The results of this experiment are important for the development of quantum metrology, the science of measuring things using quantum theory. Scientists note that the contradiction between quantum mechanics and local realism persists as the size of the system increases to a thousand massive particles. The experiment offers new possibilities for applications in quantum metrology. One of the two systems can be used as a small sensor with high spatial resolution to study fields and forces, ... >>

Prolonged stay in weightlessness inflates the brain 17.06.2023

Prolonged stay in space under conditions of weightlessness can cause the expansion of the ventricles of the brain, and their recovery to normal size takes about three years after returning to Earth. This interesting discovery was made by researchers at the University of Florida who were studying the effect of space travel on the brain structure of astronauts on the International Space Station (ISS). Inside our brain are cavities called ventricles, and they are filled with cerebrospinal fluid. This fluid performs important functions by providing nutrition and protection to the nervous tissue, as well as removing metabolic waste. However, a long stay in a space environment with zero gravity leads to changes in this system. The ventricles of the brain adapt to weightlessness and begin to expand. When astronauts return to Earth, it takes a long time for these ventricles to regain their normal size. The study was conducted on 30 astronauts, ... >>

Voice genetics: the key to hereditary timbre 17.06.2023

Researchers have discovered a gene responsible for the timbre of your voice - hoarse and low, or vice versa. During the study, scientists analyzed speech recordings of almost 13 people and their genetic data. A piece of DNA called ABCC9 has been identified that is associated with higher voices in both men and women. The ABCC9 gene sequence is also linked to heart health. Experts from the Icelandic company Decode Genetics emphasize that their data indicate a greater risk of heart problems in people with a higher timbre of voice. Previous research has shown that men with a deep voice have higher testosterone levels, a more developed upper body, and are considered more attractive and dominant. Data analysis also showed that such men run large enterprises. The researchers believe that the depth of male voices was most likely a factor in sexual selection in the past. In other words, men with lower voices had more sex. ... >>

Gym on board 16.06.2023

Australian airline Qantas is planning to install gyms on its aircraft to meet the needs of passengers and help them better cope with long flights exceeding 20 hours. New aircraft equipped with a special "health zone" in the form of a mini-gym will be available from 2025. Gyms will appear on board the Airbus A350 aircraft, which will be operated by Qantas at the end of 2025. At first, these sports areas will be available on the longest routes, such as flights from Sydney to New York and London. However, the installation of gyms will require a reduction in the number of seats in the cabin. Qantas chief executive Alan Joyce explains that the new A350s will have 100 fewer seats than the competition, but will provide more space for all classes of passengers as well as a "health zone" where they can warm up and exercise. Prior to the implementation of the project, the airline conducted a survey among passengers to find out their needs. ABOUT ... >>

Artificial embryos from stem cells 16.06.2023

Scientists at the University of Cambridge and the California Institute of Technology conducted an experiment in which they used artificial embryos created from stem cells. This approach can help in the study of genetic disorders, but raises serious ethical and legal problems. Artificial embryos were grown without the use of eggs and sperm. They do not have a heart or the rudimentary brain, but contain the cells that normally form the placenta and yolk sac. Professor Magdalena Zernitskaya-Goetz, speaking at the annual meeting of the International Stem Cell Research Society in Boston, said: "We can create models similar to human embryos by reprogramming embryonic stem cells." However, in the near future, synthetic embryos cannot be used in the clinic, as it violates the law, and it is also not known whether these structures have the potential to develop further after the early stages. Is ... >>

Wind power reaches record 1 TW 15.06.2023

An important achievement in the field of wind energy: the world's installed capacity has reached the mark of 1 terawatt (TW). After 40 years of efforts and development of the wind industry, we have reached this milestone in clean energy production. However, according to the forecasts of the Global Wind Energy Council (GWEC), we can expect to reach the mark of 2 TW in less than seven years. In the early 1970s, Danish engineers began experimenting with wind power, and this research became the basis for the modern wind industry. Since then, the global wind power industry has developed rapidly and its growth has been enormous. According to Wood Mackenzie, by the end of this year, the global installed capacity of wind energy will exceed the 1 TW mark. However, GWEC notes that we have already reached this mark, and this is confirmed by completed projects in China, the USA, Europe and Morocco. Despite an important achievement in wind power, Jonathan Cole, head of GWEC, points out that we are just getting started. ... >>

The brain of birds reacts to magnetic fields 15.06.2023

An international team of scientists has found that there is a special group of neurons in bird brains that respond to changes in the magnetic field. When a bird is in a magnetic field, these neurons fire and relay information about the direction and intensity of the field to other parts of the brain involved in orientation and navigation. Scientists conducted experiments using titmouse birds with a device that allowed changing the magnetic field under controlled conditions. They found that even a slight change in the magnetic field caused a response in the neurons of the bird's brain. These discoveries are important for our understanding of how birds use magnetic fields for navigation and orientation. It also opens up new avenues for the development of technologies that can help people solve similar problems. In the future, these studies may contribute to the development of new navigation methods for robots and autonomous systems. Understanding how birds sense magnetic fields could have important applications in a variety of ways. ... >>

Video capsule with remote control as an alternative to the endoscope 14.06.2023

The use of video capsules as an endoscopic instrument already has some history, however, they were previously uncontrollable as they completely relied on gravity and gastrointestinal peristalsis for locomotion. However, the researchers managed to overcome this limitation by creating a tablet with a camera and a remote control system. Scientists at the George Washington University School of Medicine and Health Sciences have developed a method that allows doctors to control a miniature video capsule called NaviCam that a patient swallows and passes through the entire digestive system, allowing them to visualize and photograph potentially problematic areas. An external magnet and joysticks are used to move the capsule. "Conventional endoscopy is an invasive procedure and also expensive. The magnetically guided video capsule can be used as a quick and easy way to diagnose upper pi problems." ... >>

Kitchen salt asteroid 14.06.2023

The Americans carefully studied a sample of the near-Earth asteroid Itokawa and found crystals of ordinary kitchen salt here, which could not have appeared without the presence of water. Even 13 years ago, the Japanese spacecraft Hayabusa delivered the first ever rock samples from an asteroid to Earth. This space rock turned out to be the near-Earth asteroid Itokawa, which is approximately 610 meters wide. And all these years, scientists from different countries continue to carefully study these samples. Specialists from the University of Arizona, USA, found crystals of ordinary kitchen salt in the composition of the asteroid, which could not have appeared if there was no water nearby. This again changes the idea of ​​how water could get to our planet. Scientists continue to search for answers to questions about how complex life on Earth arose. The fact that they were able to find crystals of sodium chloride or ordinary kitchen salt in the composition of the asteroid Itokawa, which could only form in the presence of water, indicates that ... >>

Transplanting a beak to a vulture 13.06.2023

As a result of a unique operation performed by veterinarians, the beak was successfully transplanted to the vulture. This white-backed vulture suffered serious damage when it was hit by a car in northwest South Africa. The incident caused the bird to lose one eye and break off its beak, which posed a serious threat to its survival as it could no longer feed. In the natural environment, she would be doomed to starvation. However, the vulture was taken to the veterinary department of the University of Pretoria, where a team of experts took on the daunting task. The first two attempts to attach an artificial acrylic beak to a bird were unsuccessful, as they did not have sufficient strength and broke when eating. The doctors decided to take a different approach and turned to the beak of another vulture. The world premiere of transplanting a beak to a vulture took only 30 minutes. The beak was attached to the damaged vulture with six screws. The bird is doing well at the moment. ... >>

Neanderthals made glue 11.06.2023

The scientists analyzed the chemical structure of tar from the Königsau cave in Germany using infrared spectroscopy and gas chromatography-mass spectrometry. They found out that the substance was created artificially by the distant ancestors of man. It turned out that birch tar was synthesized in underground chambers that limit the access of oxygen, which sheds light on the intellectual capabilities of Neanderthals. Birch tar synthesized underground contains high levels of a natural polymer called suberin, while tar obtained by burning birch bark above ground does not contain it. Noting that all samples from Königsaue were rich in suberin, the researchers are confident that Neanderthals made their glue underground. "If suberin is present only in birch tar obtained using underground techniques in low oxygen conditions, its presence in Königsaue tar clearly indicates that Neanderthals had much more ... >>

Rugged smartphone Blackview BV8900 with a thermal imager 10.06.2023

Blackview has unveiled the BV8900 rugged smartphone, featuring a giant battery, a thermal imaging camera and more. The novelty is based on the MediaTek Helio P90 SoC, which cannot be called new or productive. But the smartphone has 8 GB of RAM and 256 GB of flash memory with a microSD slot. Interestingly, the company in a press release in many places lists the amount of RAM as 16 GB, and only then explains that 8 GB of them are virtual expansion. It looks like it's becoming a new trend. An unexpected feature of the smartphone, given its platform, is the screen. It has a diagonal of 6,5 inches and a resolution of 2,4K. There is no exact value, but this is unusual for this class of smartphones. True, there is one but. On the Aliexpress manufacturer's page, the resolution is listed as 2400x1080 pixels, so perhaps 2,4K is such an original way to specify vertical resolution, which is hardly a good idea. However, there are no questions about the battery capacity. ... >>

Robotic gardening system AlphaGarden 10.06.2023

American engineers compared the success of their AlphaGarden robotic system in the garden with how professional gardeners took care of the plants. It turned out that AlphaGarden is able to independently monitor the condition of plants, watering or cutting them if necessary, just as people would do. AlphaGarden is an automated plant growing system developed with engineers from the University of California, Berkeley. It includes a platform that can sow a garden, cut and water vegetables, as well as an autonomous system that allows you to perform all the necessary manipulations in a timely and correct manner using a neural network.

Thus, AlphaGarden can be used in multicultural vegetable gardens, where a variety of plants grow at the same time. In a new study, scientists ... >>

Allergy-free eggs bred 09.06.2023

Scientists at the University of Hiroshima managed to get rid of the allergenic omucoid protein from eggs by changing the genes of some chickens. Egg allergy is common, especially in children. It is difficult to treat and affects the quality of life. Eggs are widely used in various food products, in particular, in baked goods, sauces and other foods. People with allergies should read labels carefully and avoid products containing eggs or ingredients derived from them. In addition, such patients cannot be vaccinated with vaccines made on the basis of egg white. Scientists decided to investigate how the genetics of chickens can be changed to make life easier for allergy sufferers. They focused on studying the protein ovoucoid, which is the cause of many egg allergies. It turned out that chickens with altered genes can hatch eggs without omucoid. The study used activator effector nucleases like transcription activators (TALEN), which are proteins that ... >>

Salo from a test tube 09.06.2023

Scientists at the American Tufts University have mastered a completely new method of growing fat cells and forming them into a finished product similar to animal fat. This will allow artificial meat to be supplemented with artificial fats. The technology for producing artificial meat promises to provide humanity with a tasty and healthy product without harming the environment and destroying animals. Previously, biologists have already learned how to grow muscle tissue of different animal species. Some of these products have already been approved for use and are being produced for distribution to shops and restaurants. However, the authentic taste, texture, and nutritional value of meat remains incomplete without a certain amount of fat. Tests show that consumers call beef the most delicious meat, containing approximately 36% fat. Complementing dietary artificial meat will help a new method that allows you to grow adipose tissue. To cultivate cells "in vitro", they need to be constantly fed with nutrients. ... >>

Gas storage inside coal 08.06.2023

Scientists at the University of Pennsylvania have built a prototype plant for pumping hydrogen gas into coal and extracting it from there. The researchers plan to use natural coal as a gas storage and thus store energy in it, instead of burning coal. Such an approach, engineers are sure, can revolutionize the energy sector. Scientists note that considering that environmental initiatives to preserve the environment and search for alternative energy sources are actively promoted in the world, the coal industry begins to suffer significant losses. Despite this, the mineral reserves are still very large, and this creates significant problems for the economies of countries involved in the mining industry. In addition, hydrogen is considered a promising source of energy for the future, as it is easy to obtain and when burned, it does not form harmful emissions. However, the storage of hydrogen on an industrial scale is a super-difficult task that has not been implemented yet. ... >>

A device for measuring the gravity of an asteroid 08.06.2023

When ESA's Juventas CubeSat lands on Dimorphos in 2026 to assess the aftermath of last year's spectacular collisions with NASA's DART spacecraft, its Solar System Small Body GRAvimeter (GRASS) instrument directly measures the gravity of the asteroid, which is one in a million. In September 2022, NASA's Double Asteroid Redirection Test (DART) crashed into Dimorphos orbiting the larger asteroid Didymos as part of an experiment to learn more about how to deflect potentially hazardous celestial bodies before they reach Earth. This was only half the job, because the ongoing ESA Hera mission was tasked with assessing the effects of a space impact. Part of that effort includes the Juventas CubeSat, roughly the size of two loaves of bread, which will be deployed from the Hera deep space probe and land on Dimorphos. Among a small set of instruments is the GRASS gravimeter, developed by the Royal Observatory of Bel ... >>

Ants can build landmarks, marking the way home 07.06.2023

Insects living in the desert have to travel especially long distances in search of food. Ants Cataglyphis fortis live in the Sahara. There is little food there, and in search they have to move a long distance from the nest. At the same time, the desert and flat landscape is often devoid of any natural landmarks. As a result, the ants have evolved highly unusual navigational abilities. For example, to choose a direction, they periodically check with the position of the Sun, and to track the distance, they count their steps. But if that's not enough, C. fortis can navigate by the low mounds they build themselves to mark the entrances to their underground nests. This unique behavior was discovered by German biologists from the Institute for Chemical Ecology of the Max Planck Society. An article by Markus Knaden and colleagues is published in the journal Current Biology. At first, scientists drew attention to the different heights of the mounds that ants erect on the surface, above underground ants. ... >>

Wine with gold content tastes better 07.06.2023

In addition to everything else that winemakers must consider when making the perfect bottle is the smell of the drink: at certain stages of winemaking, this smell can be unpleasant. Aromas that can be described as "rotten eggs", "rubber" and "canned corn" are often referred to as "reductive" and are created by volatile sulfur compounds (VSC) in the liquid. These compounds can affect both red and white wines, both large scale and small scale operations, and are a costly headache for the industry. Now, researchers at the Australian Wine Research Institute and Flinders University in Australia have come up with a new solution to the problem: gold nanoparticles that can quickly and environmentally remove many sulfurs. The researchers chose gold nanoparticles because of the way gold binds to certain sulfur molecules. The team applied a specially developed thin polymer plasma coating to the surface of the neutral ... >>

Powder that purifies water from E. coli 06.06.2023

Scientists at Stanford University have developed a cheap method to purify water using powder and sunlight. Existing chemical water treatment technologies can leave toxic by-products and waste a lot of resources. The new approach is based on the addition of harmless metal powder to polluted water, which absorbs both ultraviolet radiation and sunlight. The powder consists of nanoparticles of aluminum oxide, molybdenum sulfide, copper and iron oxide. The mixture is then exposed to sunlight. After absorbing solar photons, the molybdenum sulfide catalyst allows photons to displace electrons. The released electrons then react with water, creating hydrogen peroxide and hydroxyl radicals. These compounds quickly destroy bacteria by damaging cell membranes. In an experiment with a 200 ml glass of water contaminated with approximately one million E. coli bacteria per ml, all pathogens were killed. ... >>

Candies that restore tooth enamel 06.06.2023

American scientists from the University of Washington have developed lozenges that support and restore tooth enamel. The drug has already been tested on rats and extracted teeth from humans and pigs. Mint flavored lollipops are based on a genetically engineered peptide derived from the protein amelogenin. Amelogenin is a key protein in the formation of enamel and tooth crown. The peptide, which will be contained in the candy, will connect to the dentin - the layer of the tooth that is located under the enamel. Thus, a new layer of enamel will be created. Scientists predict that to maintain the strength of tooth enamel, it will be enough to use one lozenge a day, and two will already help restore damaged enamel. ... >>

Electrical Brain Stimulation Improves Cognitive Ability 05.06.2023

American researchers conducted a meta-analysis of 102 scientific papers on the effects of non-invasive electrical brain stimulation and concluded that the procedure improves cognitive abilities in both healthy adults and the elderly and patients with neuropsychiatric disorders. Rhythmic fluctuations in the neuronal activity of the brain are one of the most characteristic factors associated with cognitive abilities. Violations of these fluctuations are associated with differences in mental abilities between people, as well as with such deviations as autism spectrum disorders or schizophrenia. In some cases, it is possible to normalize this brain activity through electrical stimulation of the brain with alternating current transcranially - from the outside through the scalp and skull. This treatment technique has been actively studied in recent years, but data on its effectiveness are scattered. To combine them and draw conclusions began scientists at Boston University with American colleagues. The researchers analyzed the ... >>

Ultra-stable perovskite-based solar cells with protective adhesive 05.06.2023

Silicon solar cells may have had a few decades of head start, but Perovsk is rapidly closing the gap in just 15 years. Not only does its efficiency approach that of silicon, it's also cheaper, lighter, and more flexible, but it has one major drawback - durability. Over prolonged exposure to the elements, perovskites tend to break down, which in turn is not good for devices designed to be exposed to the sun all day, every day for decades. Scientists have experimented with amplifying them by adding bulk molecules, 2D additives, carbon nanodots from hair, or quantum dots, among other things. But the new treatment allows perovskite solar cells to operate at 99% efficiency after 1000 hours of use. The team used a new adhesive to protect the perovskites. It's called BondLynx and was originally manufactured by the Canadian materials company XlynX for other uses before it was tested in the sun. ... >>

The glaciers of the Arctic are filled with life 04.06.2023

A new study has proven that the Arctic ice is not at all as lifeless as it might seem at first glance. It may seem that the glaciers of the Arctic are completely devoid of life, but scientists assure that this is not at all the case. In fact, the ice and snow carpets in Greenland and Iceland are literally filled with microscopic life forms. Moreover, like seasonal zombies, many of these organisms hibernate and wake up from a frosty sleep with the onset of summer and the melting of glaciers. According to a microbiologist at the University of Aarhus in Sweden, Alexander Anesio, even in a small pool of glacier meltwater, almost 4 different species can easily be awake. The researchers note that for the most part, these microscopic organisms thrive on bacteria, algae, viruses, and microscopic fungi. In fact, they are a whole ecosystem, the existence of which the researchers knew nothing about for a long time. Everything changed when scientists studied ice and sleep. ... >>

Robots work inside people 04.06.2023

US scientists have developed miniature robots capable of delivering medicines directly to the affected organ. Biological "fins" - bacteria and spermatozoa with a non-linear nature of movement were taken as the basis. Microrobots made from biocompatible polymers have a spherical cavity inside. Devices vibrate and move. The works also have asymmetrical fins, causing them to orbit. The mechanism has already been tested on the bladder of a laboratory mouse. A group of microrobots was able to attach to the wall of the bladder and transfer more than 90% of the drugs to the organ in 2 days. It is believed that this will allow more effective treatment of various diseases and reduce side effects. ... >>

Microplastics can enter the brain 03.06.2023

Tiny plastic particles enter the body with food, water and air, accumulating in tissues and cells. This is no longer news, and take it for granted. Scientists even brought out the name for this phenomenon - "plasticosis". But it was believed that the central nervous system is sufficiently protected from the penetration of foreign material by the blood-brain barrier. However, scientists have found that plastic is able to overcome it. And within a couple of hours after eating, microplastics can even penetrate the brain. The millions of tons of plastic that end up in nature every year are not dead weight. Slowly decomposing, they spread in soil, water and air, getting into living organisms. Tiny plastic particles accumulate in plants and animals. And subsequently can cause the most serious health problems. How does plastic find its way into our fabrics? With food, it ends up in the intestines, from where it is carried by blood and other fluids throughout the body. Penetrates into tissues, even affects cells. ... >>

NASA to pay 18000 euros for two months in bed 03.06.2023

The European Space Agency is conducting a new experiment. Participants need to spend two months lying down. For this they will pay 18 thousand euros. The idea of ​​getting paid to stay in bed for two months may seem too good to be true. But this is exactly what the European Space Agency (ESA) proposes. They conduct an experiment with 12 volunteers who, as part of a new study, are in beds tilted 88 degrees below the horizontal for 6 days with their legs up. Among the challenges for volunteers are also: eating, showering, toileting, riding special bicycles (located at the bottom of the bed), medical tests - all in the supine position throughout the study. Participants in the experiment will receive 18 euros each. Everything is simple - for astronauts. ESA hopes that the findings will help explore potential countermeasures to the changes that the human body is undergoing in space. There are currently 000 males participating in the study. ... >>

A method for accurately determining biological age has been created 02.06.2023

A group of biologists from Germany has created a way to accurately determine the biological age of an organism using gene analysis. Determining the correct biological age is important for physicians to understand the influence of the environment, the appointment of a daily regimen or the choice of medications for treatment. Especially the new method will be in demand in gerontology. It is the biological age of a person that is crucial for most diseases of the body, it affects the extinction of the function of various systems and organs. People age at different rates, and often actual age may not match biological age. At the same time, the correct determination of biological age can be extremely important when prescribing treatment, rejuvenation methods for recovery after surgical interventions, so scientists have always been looking for accurate biomarkers that can indicate the necessary data with 100% accuracy. Biologists from the University of Cologne decided to use a set of certain genes to calculate the biowiki, which, when ... >>

Growing mushrooms inside wind turbines 02.06.2023

The vast majority of wind turbine blades will end up in landfill, largely offsetting their contribution to low-carbon energy. By 2050, this will amount to over 43 million tons of non-recyclable waste. Scientists from the University of California at Davis have tackled the issue of environmental recycling of wind turbine blades, using fungal mycelium, an organic substrate and a bamboo frame as the basis for their manufacture. A group of researchers addressed the issues of compatibility of the mycelium of a number of fungi, including edible ones, substrates and scaffold materials. The developers are sure that mycelium in combination with a substrate from organic waste can replace polyurethane and acrylic. Actually, the development of organic paddles began with a 2018 project to create an organic helmet for cyclists with mycelium lining. Thanks to a native of China who got into the group, there was someone to weave the frame of the blade from bamboo. Without this specialist, they admit at the university, the development of the project is not possible. ... >>

Computer on the water 01.06.2023

Scientists from Australia have presented a prototype "reservoir" computer that performs calculations in a container of water and predicts the future. The behavior of waves on water is subject to strict physical laws and leads to a predictable result. According to scientists, their invention is an analog computer that is able to perform a number of tasks faster and more accurately than any digital platform. The researchers supported the prototype with an effective mathematical model (it is based on the elements of the operation of neural networks), which the scientists described in their scientific article. Structurally, the prototype of the "reservoir" computer is a long container with running water. The role of the input circuit is played by a pump that creates waves on the surface of running water. It should be noted that scientists were interested not in an ordinary wave that quickly loses strength, but in a structurally stable isolated wave propagating in a nonlinear medium - the so-called soliton. The presented prototype showed that the analog wave platform sp ... >>

Space data transmission using a laser 31.05.2023

A team of researchers from NASA, MIT, Terran Orbital and NASA's Jet Propulsion Laboratory (JPL) ground station has set a record for transmitting data to an earth station using laser communications. The satellite was able to transmit data at a speed of 200 Gbps. With such indicators, you can transfer more than 2 terabytes of data in one 5-minute pass over the ground station. Communication is provided by the TeraByte InfraRed Delivery (TBIRD) system, located at an altitude of about 530 km above the Earth's surface. Located aboard NASA's Pathfinder Technology Demonstrator 3 (PTD-3) satellite, TBIRD was launched into orbit as part of the joint SpaceX Transporter-5 mission on May 25, 2022. The PTD-3 satellite weighs approximately 12 kg, and its TBIRD payload is no larger than a box of tissues. Launched into space last May, the laser reached 100 Gb/s downlink speed by June with a ground-based receiver in California. It was 100 times faster than high ... >>

Male characters in games speak twice as often as females 30.05.2023

Scientists from the Universities of Glasgow and Cardiff presented the results of their research paper entitled "Gender Bias in Video Game Dialogue" in the academic journal Royal Society. This study was an in-depth analysis of how gender affects dialogue in video games. In the course of their research, they analyzed 50 role-playing games created both now and 10-20 years ago. These games included such popular titles as Mass Effect, The Elder Scrolls V: Skyrim, Final Fantasy XIII, Kingdom Hearts, and Star Wars: Knights of the Old Republic. According to the results of the study, scientists found that male characters say about twice as many lines as female characters in the role of NPCs (non-playable characters). In addition, female characters spoke more dialogue lines in only 6% of the games studied. In only 3% of cases, female NPCs had more than 50% of the lines of the total. The second female characters also turned out to be less "talking" compared to ... >>

Space rocket powered by coal 29.05.2023

Official sources from the Chinese Space Corporation reported that the Tianlong-2 rocket (Tianlong-2) launched in April by the private company Space Pioneer ran on aviation kerosene obtained from coal. This was the first such test of a liquid fuel derived from petroleum. Thus, China is trying to reduce dependence on imported energy resources and ensure fuel security in the aerospace industry. China did not have its own oil (and it was mostly of inadequate quality) and a lot of coal. Coal liquefaction technology has responded to challenges in the supply chains of petroleum products. According to experts, a possible conflict with Taiwan is guaranteed to lead to a naval blockade of China and blocking oil supplies to the country along the main sea route. The deficit will partially have to be closed with our own resources. Therefore, in China, they began to create lines for the conversion of coal into aviation kerosene of the highest quality. Launch vehicle "Tianlong-2" is equipped with an engine ... >>

Women experience less pain when a man is around 29.05.2023

Big girls don't cry, especially when there's a man around. This goes against the stereotypical notion that women love attention and sympathy. Scientists from Murdoch University, Australia, found that women report less pain when men take the test. In a new study, scientists have determined how gender stereotypes affect self-determination of pain levels. Male and female participants rated the pain they felt with heat, pressure, studs, and high-frequency electrical stimulation. A team of male or female experimenters applied stimuli, and then the researchers analyzed how their gender affected pain scores. Evidence suggests that women are more likely to catastrophize pain. However, this moment was present only if the experimenter was a woman. Before men, women reported lower levels of pain. ... >>

Casio watch in the style of the series Stranger Things 28.05.2023

Casio has announced the A120WEST, a Netflix collaboration inspired by the mega-hit "Stranger Things". Stranger Things is a Netflix action adventure series set in the small American town of Gokins, Indiana in the 1980s. One day, a 12-year-old boy goes missing in the city. His friends, family and the local police search for answers, but find a little girl with the number 011 on her wrist and become involved in unraveling an extreme mystery involving top-secret experiments, terrifying supernatural forces, monsters and the world of Dogoridrigo. The design of the new watch contains many references to the culture of the 1980s and to the series itself, especially to the alternate dimension Dogoridrigo, which exists in parallel with the human world. The dial depicts the world of Marvelous Wonderland characters, the bright buttons on the front are reminiscent of the 1980s, and the Demogorgon in the center. When you press the button with LED backlight, the ... >>

A new way to cool semiconductors 28.05.2023

Engineers from the Korea Advanced Institute of Technology (KAIST) have improved the thermal conductivity of a semiconductor device by using a surface plasmon polariton formed on the surface of a titanium film. The study opens up a new way to deal with overheating in high-performance microelectronics. A surface plasmon polariton is a wave that is formed on the surface of a metal as a result of a strong interaction between the electromagnetic field at the interface between the dielectric and the metal and free electrons on the surface of the latter. These waves resemble oscillating particles, the authors of the study explain. They used a thin film of titanium deposited on a glass substrate to generate surface waves capable of transporting heat. In a series of experiments, the engineers showed that using a film 100 nm wide and with a radius of about 3 cm, thermal conductivity can be increased by 25%. Because a new heat transfer mode occurs when a thin layer of ... >>

Dutch scientist Bjorn Karmann created a camera that takes pictures without a lens. The device is called Paragraphica. The camera uses location data and artificial intelligence. So a certain place and moment is displayed. Address, weather, time of day and nearby places are used. “As AI models become more and more conscious, it is difficult to imagine how they can see our physical world. This camera offers a way of knowing the world around us that is not limited to visual perception,” says the creator. ... >>

Compact tokamak warmed up to a record 100 million kelvins 27.05.2023

Researchers from the British company Tokamak Energy Ltd, Oak Ridge National Laboratory (USA), and the Institute for Energy and Climate Research (Germany) have set a plasma temperature record for a spherical tokamak. The ST40 is compact: the size of the working chamber is no more than 80 centimeters in diameter. The ions inside the reactor were heated to over 100 million kelvins (about 100 million degrees Celsius, or 8,6 kiloelectronvolts). "An ion temperature of over five kiloelectronvolts has never been achieved before in any spherical tokamak. They were obtained only in much larger devices with a much higher plasma heating power," the scientists explained. Their work has been published in the journal Nuclear Fusion. Note that for small spherical tokamaks, reaching such temperatures is a very difficult task. Therefore, the fact that this was achieved on a commercial spheromak looks like a good achievement for the British. At the same time, against the background of the most effective ... >>

Air powered generator 26.05.2023

Scientists at the University of Massachusetts Amherst have created a device to generate electricity from thin air. In particular, the new "air generator", or Air-gen, which is based on microscopic holes less than 100 nanometers in size, which is a thousand times smaller than a human hair, can receive electricity from water droplets in the air. When moist air passes through the miniature holes in the Air-gen material, the water molecules come into direct contact first with the top and then with the bottom chamber in the film. This creates an imbalance of charges, that is, electricity. In addition, further research results showed that virtually any material can become an Air-gen device, as long as it is 100 nanometers or smaller. The researchers hope this technology could help fight climate change by serving as an alternative to fossil fuels. ... >>

Smart people think slower 26.05.2023

Do smart people think faster? According to the results of a study by a group of scientists from Germany and Spain, not always, and in the case of solving complex problems, some advantages go to people with a less developed intellect. The adult human brain consists of billions of neurons connected by numerous connections. These complex and sometimes intricate networks are both the key to the amazing possibilities of the brain and the main difficulties in the way of studying it. Since it is difficult to work with the brain of a living person, researchers are increasingly turning to computer simulations using digital brain scans, such as magnetic resonance imaging (MRI), as well as mathematical models based on theoretical knowledge about biological processes. At first, this allows you to build a "general" model of the human brain, but then scientists refine it using data from individual people and create "personalized" brain models. To explore how general indicators of the level ... >>

Invented fabric that mosquitoes won't bite through 25.05.2023

American scientists have developed a thin fabric through which mosquitoes cannot advance their proboscis. This is a fabric with a special weave, quite light, so that in summer clothes made from such material will not be hot. The publication writes that Auburn University professor John Beckman during a hiking trip decided to figure out which fabrics are inaccessible to mosquito punctures. He put on sleeves made of different fabrics and held out his hand to a container filled with mosquitoes to check which fabric was easily bitten by bloodsuckers. Mosquitoes coped with most fabrics without difficulty. The most inaccessible to mosquitoes were knitted fabrics formed not due to interlaced threads, but loops. Scientists took advantage of this opportunity and tested the effectiveness of the protection provided by different weaving options. Initially, scientists noticed that the interlock fabric, consisting of two layers of loops, proved to be the best. An additional increase in the thickness of the threads and a decrease in the size of the loops ... >>

A camera that works like the retina of the human eye 25.05.2023

Engineers at the University of Pennsylvania have developed a camera that works like the retina of the human eye. Three types of photoreceptors imitate the retina of the eye, and an artificial neural network processes the resulting images. The basis of the device is a matrix of sensors from narrow-band perovskite photodetectors that imitate the cones of the retina. The matrix is ​​connected to a neuromorphic algorithm that mimics a neural network to process information and obtain images with high accuracy. The researchers believe that a new kind of sensor can be used as an alternative to filters in modern cameras. Silicon sensors are sensitive to all parts of the spectrum, so light filters are installed in front of them, which pass only certain waves, but reduce the clarity and sensitivity of the camera. "We borrowed design from nature - our retinas contain cones that are sensitive to red, green and blue light, and a neural network that starts processing what ... >>

Dream control device 24.05.2023

What if there was a device that could control dreams? What if you could go to bed and were told that you were dreaming? This is somewhat the main idea of ​​the new research conducted by MIT scientists and the device they have created. The premise here sounds like it was ripped out of Christopher Nolan's Inception, but it's not science fiction. A team of scientists used targeted dream incubation and created a dream control device that helped boost creative performance after sleep. The study is built on assumptions about how dreams and creativity are related. That's why MIT scientists decided to investigate this connection and see if they could create a device that would control dreams. The idea was to see if they could insert specific themes into dreams, which would allow them to effectively determine what the dreamer was dreaming of, at least to a certain extent. ... >>

wooden transistor 24.05.2023

American electronics experts have unveiled a revolutionary achievement: the world's first wooden electrical transistor. This new development marks a significant step forward in the quest for more sustainable and environmentally friendly technologies. The transistor, a fundamental building block of modern electronics, is usually made from silicon, a material that is resource-intensive to manufacture and difficult to recycle. And wood is a renewable and rich resource that can be harvested without harming the environment. The wood transistor was created by a team of scientists at the University of Maryland who used a process called "delignification" to remove a key component of wood known as lignin. What was left was a material called cellulose nanofibrils, which were then coated with a thin layer of gold to create the transistor's electrodes. The resulting wooden transistor has several advantages. ... >>

Loneliness is dangerous 23.05.2023

Scientists at Harvard University have found a way to preserve longevity. Turns out it's all about social relationships. The results of the study proved that frequent and active communication in the long run helps to improve health and prolong life. Social preparation helps to counter the effects of chronic stress. Psychiatrist and psychoanalyst at Harvard Medical School Robert Waldinger believes that the formula for health and happiness depends largely on positive relationships with other people. Waldinger warned that if you regularly feel lonely and isolated from other people, it can be as dangerous as becoming obese or smoking half a pack of cigarettes a day. Abandoned social skills can atrophy like unused muscles. Scientists do not give any clear recommendations. They only remind you that the point here is not the number of friends or acquaintances, but how fully you communicate with them. Even if you have several relatives ... >>

Power lines interfere with bees 23.05.2023

The wires of high-voltage power lines are surrounded by electromagnetic fields, which have a noticeable effect on the state and behavior of bees. Biologists have shown that near such lines, insects experience stress and pollinate plants worse. Special receptors allow bees to sense natural electromagnetic fields, using them for orientation and flight navigation. But people also create such fields: they surround any wire through which electricity flows, and if the currents are strong enough, the fields can have a noticeable effect on the behavior of bees. Thus, it has already been shown that near high-voltage lines these insects become aggressive and often go astray. A new study by Chilean biologists from the University of Talca has shown that power lines prevent bees from performing their main function for nature - to pollinate flowering plants. To begin with, scientists conducted experiments in the laboratory. One hundred honey bees (Apis mellifera) were exposed for three minutes to electromagnetic fields generated by ... >>

World record for underwater life set 22.05.2023

University of South Florida professor Joseph Dituri, a member of the Neptune 100 research project, set a new world record for the longest stay under water. The explorer has been living in an underwater hotel off the coast of Florida since March 1. The previous record was set in the same place in 2014 and was 73 days 2 hours and 34 minutes. Although the world record is set, the explorer has no plans to stop: his goal is to spend 100 days in an underwater hotel. If all goes according to plan, the underwater mission will end on June 9th. "Neptune 100" is a research project aimed at studying the physiological and psychological effects that the human body experiences when exposed to extreme pressure for a long time. In addition, the second goal of the project is to draw attention to ongoing marine research and the importance of conserving ocean resources. Dituri conducts daily experiments and collects medical data for analysis. He studies how weight changes, muscle structure, ... >>

Nuwa Pen digitizes handwritten text in real time 22.05.2023

Nuwa Pen, developed by the Dutch startup of the same name, is an artificial intelligence ballpoint pen. It has built-in electronic elements, but retains the usual writing functions - for those who, in the era of computers and voice input, still prefer handwriting rather than typing on the keyboard. The gadget is made in the format of a classic pen, but thanks to the electronic filling, it allows you to instantly digitize handwritten text. An important difference between the device and its analogues is that it can be written on ordinary paper, and not only on special paper. The pen was developed by a startup of the same name from the Netherlands. It will be produced in an aluminum case with a length of 150 millimeters and involves the use of replaceable D1 format ink cartridges. At the bottom there are three cameras and an IR LED so that the pen can be used in low light conditions. The pen is powered by an Arm Cortex M4 chip and uses specially designed software. ... >>

Artificial intelligence will predict magnetic storms 21.05.2023

Scientists have developed an algorithm that can track and predict magnetic storms every minute. Thanks to artificial intelligence, experts will have about 30 minutes before a deadly magnetic storm will cover the Earth. The NASA team is reportedly actively applying artificial intelligence models to solar storm data to develop an early warning system. In their opinion, AI can report the planet about 30 minutes before a potentially destructive magnetic storm will cover the Earth. This time is due to the fact that light travels faster than the material ejected from the Sun. In some cases, such as in Quebec about 35 years ago, solar storms can cut off electricity for several hours. More extreme events, such as the Carrington solar storm more than 150 years ago, could lead to widespread destruction of electrical and communications infrastructure if they occur in modern times. Researchers have long recognized this problem ... >>

Stress changes the brain 20.05.2023

Working with mice, the researchers found that a single stressful event triggered rapid and lasting changes in brain cells that cleared the brain of debris. Research by Si-Kwong Jun Liu, MD, professor of cell biology and anatomy at the Center for Health Sciences at Louisiana State University New Orleans, has shown how stress changes brain structure. It is noted that based on the results, a potential therapeutic target for prevention and treatment can be identified. Working with mice, Liu and her research team found that a single stressful event triggered rapid and lasting changes in astrocytes, the cells in the brain that clear away debris. The stressful episode caused the tips of astrocytes to move away from synapses, through which information is transmitted from one cell to another. The team also uncovered a mechanism leading to communication disruption. They found that during a stressful event, the hormone norepinephrine inhibits the molecular pathway. ... >>

Purification of water from uranium using magnetic bacteria 20.05.2023

German researchers from the Helmholtz Center Dresden-Rossendorf have developed a water purification technology using magnetotactic bacteria. Microorganisms accumulate dissolved heavy metal in their cell walls, and a magnetic field is used to remove them from the water. Nanoscopic magnetic crystals are formed inside the cells of magnetotactic microbes. Each individual magnetic crystal is enclosed in a protective membrane. Together they form a magnetosome, an organelle that bacteria use to navigate the Earth's magnetic field. In their own experiments, the researchers showed that magnetotactic bacteria can survive at neutral pH even in aquatic solutions containing relatively high concentrations of uranium. At the same time, they bind this heavy metal in the cell walls and it does not penetrate into the cell and does not interact with the magnetosome. This is an excellent basis for water purification associated with mining, the authors of the study say. ... >>

Oxygen ion battery 19.05.2023

Lithium-ion batteries, while commonplace in the modern world and powering everything from electric vehicles to smartphones, are not necessarily the best solution for all applications. Researchers at the Technical University of Vienna have made a breakthrough by creating an oxygen-ion battery that has several significant advantages. While the battery may not match the energy density of Lithium-Ion batteries, its capacity does not permanently decrease over time, allowing the battery to last for a very long time. The manufacture of oxygen-ion batteries does not need scarce elements and uses non-combustible materials. The innovative battery concept has already led to a patent application filed in cooperation with partners in Spain. These oxygen-ion batteries could be an outstanding solution for large-scale energy storage systems such as those required to store electricity from renewable sources. Ceramic materials, from ... >>

Corn that does not require cooking 19.05.2023

A new variety of corn has been developed that can be eaten without cooking. This was succeeded by breeders from Vietnam. Corn has a high water content and low starch content. In addition, the new sweet corn variety SSW18 has a pleasant fresh fruit flavor, high yield and disease resistance. It was created at the Institute of Plant Research and Development of the Vietnam National University of Agriculture. We worked on the project for eight years, soon corn will appear on the markets. Compared to regular corn with a sweetness level of 12-15 degrees Brix, the sweetness in Vietnamese corn is 18 degrees. Despite the high sugar content, its effect is different from that of glucose or sucrose. This means that people with diabetes or a diet can safely eat this corn. SSW18 was created by selection without genetic changes. Due to the low starch content, this corn can not be boiled, the taste will still be preserved. While the variety is growing ... >>

Europe's largest solar station launched 18.05.2023

In Turkey, in the province of Konya, the largest solar power plant in Europe, Karapinar, was put into operation. It has a capacity of 1350 MW and consists of 3256038 solar panels. The area of ​​the station is 20 million m2. The project was implemented with the financial support of the UK government, because its cost is $1 billion. Karapinar will increase the share of installed capacity of Turkish solar energy by 20%. SES will be able to produce annually 3 billion kW of electricity, that is, 1% of the total electricity consumption in the country. The station will be able to provide energy to about two million people. The solar plant will also reduce emissions by 2 million tons. ... >>

Minimizing the harm from sleep deprivation 18.05.2023

Researchers at the Guangzhou Medical University (China) have found a way to reduce the negative effects of lack of sleep. They concluded that the risk of early death caused by lack of sleep can be reduced through exercise. Scientists analyzed data from 92 people aged 40 to 73 who were asked to wear an accelerometer bracelet. During the seven years that the experiment lasted, 3080 participants died - 1074 people died from cardiovascular diseases and 1871 from cancer. The subjects were divided into three categories according to the duration of sleep - short (less than six hours), normal (from six to eight hours) or long (more than eight hours), as well as the level of physical activity - low, medium and high. Also, the intensity of sports activities was taken into account - from moderate to intense. The findings were adjusted for age, gender, ethnicity, deprivation, educational level, body mass index, diet, harmful ... >>

Clothing self-healing technology 17.05.2023

Researchers from the UK drew attention to the unusual properties of materials created on the basis of mushroom mycelium. It turned out that it can be used as an alternative to conventional fabric. In addition, mycelia demonstrate the ability to self-repair sufficiently to reproduce the conditions in which they were grown. Recent experiments have shown that the prototype mycelium-based material is able to plug holes and openings. After regeneration, the strength of the restored areas is not inferior to the strength of intact fragments, although visually they will differ. The process of mycelium recovery takes about two days, but scientists believe that this time can be reduced. The new approach to growing mushrooms does not involve the destruction of chlamydospores (spores that help the fungus survive in adverse conditions - such as drought or low temperatures). Also, if necessary, chlamydospores can be "revived" in the laboratory. Scientists are sure that thanks to this discovery in ... >>

Drinking water from lunar soil 17.05.2023

The lunar soil contains water, but it is in a closed state, and not freely available to meet the needs of the astronauts. However, scientists have discovered a way to use this water for refreshment - by heating a cup of lunar soil in the microwave. Water on the Moon is found in regolith - surface lunar dust. It is more in the frozen sediments at the poles of the Moon, which never see direct sunlight. This discovery means that astronauts going to the moon will be able to carry fewer supplies of water with them. But how to get drinking water from regolith? Scientists from the Open University and the University of Central Florida are demonstrating that a conventional microwave can do the job. Scientists used two types of simulated regolith, simulating the soil of the highlands and sea plains of the Moon, and added water to it in an amount from 3% to 15% of the total weight, which corresponds to estimates of the water content in the lunar soil. After that, the regolith samples were heated ... >>

Motorcycle powered by beer 16.05.2023

Inventor from Minnesota, USA, Kai Mikaelson presented a motorcycle powered by beer, which he created in his garage in Bloomington. Instead of a gasoline engine, the bike has a 14-gallon barrel with a heating coil that turns the beer into superheated steam that propels the vehicle forward. According to the inventor's estimates, the motorcycle is capable of speeds up to 150 miles (240 km) per hour. Mikaelson himself explained his choice of fuel by the fact that gasoline prices are rising, and he, as a non-drinker, could not think of a better way than to use beer as fuel. The bike has yet to be tested on the drag strip to see what it's capable of, but Michaelson's son Buddy said his father plans to convert the bike to all fluids, allowing it to be used not only for fun, but also for more serious purposes. Mikaelson and his son Buddy hope that their new inventive masterpiece will attract the attention of the world community and become the object of ... >>

edible batteries 16.05.2023

Researchers at the Italian Institute of Technology (IIT) have created edible rechargeable batteries that could make medical devices or toys safer for children. The battery prototype uses riboflavin (vitamin B2) as the anode and quercetin as the cathode. Nori seaweed serves as a separator to help avoid short circuits, food-grade gold contacts are connected to electrodes with beeswax, and activated charcoal is used to increase electrical conductivity. The battery operates at 0,65V and can deliver up to 48µA for 12 minutes or a few microamps for an hour. The battery's edible composition makes it safer to ingest, so it can be used to power small electronic devices for short-term medical procedures. Future versions with higher power and/or longer life cycles could replace toxic batteries in implanted medical devices. Also their ... >>

Method of non-surgical treatment of neurological diseases 15.05.2023

American scientists have developed a non-invasive way to remove problematic neural circuits, allowing you to treat serious neurological diseases without the usual brain surgery. Researchers at the University of Virginia School of Medicine, along with colleagues at Stanford University, have for the first time used not a scalpel or probe to penetrate the brain, but low-intensity ultrasonic waves combined with neurotoxin-carrying microbubbles. This allowed them to target the problem cells and kill them, while preserving the surrounding healthy cells and the overall architecture of neural connections, while currently available surgical approaches damage all cells in the treated area of ​​the brain. Scientists believe that their discovery could revolutionize the treatment of the most complex neurological diseases, such as epilepsy, movement disorders and many others. This new surgical strategy could replace existing neurosurgical procedures ... >>

Thermonuclear fusion with a magnetized target 15.05.2023

A revolutionary idea proposed by a group of scientists at the Massachusetts Institute of Technology (MIT) could revolutionize space travel by increasing the power of future space missions by 100 times. The idea involves using a type of nuclear fusion called magnetized target fusion to propel the spacecraft. Currently, most space missions rely on chemical rockets, which are limited by the amount of fuel they can carry. This means that missions to deep space, such as to Mars or beyond, can take years and require huge amounts of fuel. The new proposal aims to solve this problem by using magnetized target fusion to provide a virtually unlimited energy source. Thermonuclear fusion on magnetized targets is a type of nuclear fusion that involves compressing and heating the target plasma using magnetic fields. This process ... >>

Moss is vital to the planet 14.05.2023

More like a green carpet than a forest or pasture, the humble moss has amazing power to be such a small plant. In a new study, researchers have discovered how important this diverse group of small plant plants is to ecosystems around the world. Using moss samples from more than 9,4 sites in eight different ecosystems, scientists at the University of New South Wales, Australia have calculated that the plant's populations cover a stunning XNUMX million square kilometers in the environmental types studied. This can be compared to the size of China or Canada. Ancestors of all modern living plants, these ancient organisms have a more simplistic structure than their more modern descendants, with twigs filled with tiny leaves, typically only one cell thick. But that doesn't make them any less powerful. Moss does not have the plumbing that a normal plant called xylem and phloem have, through which water moves. But the moss survives by gathering in ... >>

Only women should be the first to fly to Mars 13.05.2023

Scientists from the European Space Agency (ESA) have presented a new study in which they argue that a planned manned mission to Mars should only consist of women. According to them, this will save tens of millions of dollars. NASA plans to send the first manned mission to Mars as early as the 2030s and may include a female astronaut in the crew, as in the upcoming flight to the Moon. ESA scientists conducted a study to determine which astronauts are best suited for the first flight to Mars. The results show that the first crew to fly to the Red Planet should be made up entirely of women. Scientists believe that in terms of resource use, this will be the most rational crew. A one-way flight to Mars takes an average of 7 months, which means that the total duration of the flight, including the return to Earth, can take up to 2 years. Although this term can increase for various reasons. ESA scientists have modeled the duration ... >>

Sea lions trained to play video games 13.05.2023

The US Navy trained three sea lions to play video games that help enrich the environment of kept animals, promote their well-being and explore their cognitive abilities. Sea lions have successfully completed essentially simple, but not essentially, video games that require them to complete a maze or grab a moving target. To do this, they used a game console created especially for them - mobile, inexpensive and convenient for pinnipeds. It was a plastic cart with a 27-inch monitor attached to it and a controller that consisted of four crosswise buttons. By pressing them with the muzzle, the animal can move the cursor that it sees on the monitor. For the successful completion of the level, the workers reward the sea lions with fish. But according to the researchers, the animals already enjoy the game itself, and spend as much time on it as they want. The benefits of video games for pinnipeds are not only that scientists can explore ... >>

A new protein that controls the red color of strawberries identified 12.05.2023

A research team from the University of Córdoba has described a new transcription factor that regulates the production of anthocyanins when strawberries ripen, responsible for giving them a red hue. Strawberry is a fruit that stands out for its color, aroma, flavor and texture. These aspects, known as organoleptic properties that determine their quality and the benefits of potential consumers, as well as insects that disperse seeds, contributing to the further growth of future plants, appear during the ripening of strawberries. The Plant Biotechnology and Pharmacognosy Research Group at the University of Córdoba, led by Juan Muñoz Blanca, has been studying the genetic regulation of strawberry ripening for several years and has now gone one step further in their understanding of this key process by discovering a new protein involved in controlling the red color of the fruit. It is known as the transcription factor protein (FaMYB123), which is responsible for the activation or inhibition of ... >>

Found an explanation for the origin of diamond deposits 12.05.2023

Scientists from the University of Wollongong (Australia) have found that the rise of diamonds from the bowels of the Earth to the surface occurs as a result of kimberlite eruptions due to giant heat columns emanating from a depth of 2900 kilometers near the planet's core. Kimberlite eruptions, leaving behind a diamond deposit in the form of a pipe in the earth's crust, have occurred hundreds of times over the past 200 million years. Signs of eruptions have been found around the world, including 788 in Canada, 158 in South Africa, 71 in Angola and 70 in Brazil. In the 1980s, it was shown that kimberlite eruptions could be associated with small mantle plumes between the mantle and the core. The researchers used supercomputers to build XNUMXD geodynamic models of global mantle convection over a billion years, including that associated with the subduction zone where the Pacific Plate is subducting under the continental South American Plate. It turned out that the very deep layers of the Earth are connected to the surface with the help of wide ... >>

The Internet can reduce the risk of dementia 11.05.2023

A study from Indiana University found that spending more time online can reduce your risk of developing dementia. This is very important news as dementia is one of the most common neurodegenerative diseases that robs people of their memory and ability to understand the world around them. The researchers examined data from nearly 4000 adults who participated in the Longitudinal Aging Study Amsterdam. The study participants were divided into two groups - those who spent more than two hours a day on the Internet, and those who spent less than two hours a day. The researchers compared the brain health of the two groups. It turned out that those who spent more than two hours a day on the Internet had a 30% lower risk of developing dementia than those who spent less than two hours a day. These results support previous research that also showed that being active online can reduce the risk of dementia and other neurodegens. ... >>

Memory Samsung DRAM CXL 2.0 128 GB 10.05.2023

Samsung has introduced the world's first DRAM solution based on the new CXL 2.0 standard. This 128 GB DRAM is designed for use in high performance computing devices and servers.

Growing stem cells on the ISS 10.05.2023

Scientists will send stem cells into space to investigate the effects of weak gravity or microgravity in space on them. Induced pluripotent stem cells (iPSCs), a type of stem cells that can develop into the three main groups of cells that make up the human body, will be cultured in space aboard the International Space Station (ISS) by astronauts flying on the private Axiom Space Ax 2 mission. The mission is scheduled aboard a SpaceX Falcon 9 rocket on May 21 from the Kennedy Space Center in Florida. Growing these cells and allowing them to differentiate in space will allow researchers to determine whether microgravity affects how iPSCs develop into other cell types, such as brain and heart cells. The iPSC is a powerful cell type that has been reprogrammed from an adult cell to return to a state called "pluripotency". Being in this state, the cell can turn into almost any type ... >>

Cats get irritated when people ignore them 09.05.2023

Scientists from the University of Paris Nanterre conducted an experiment in a cat cafe to find a way to please cats. The study was conducted by scientists from the Laboratory of Comparative Ethology and Cognition of the University of Paris Nanterre under the direction of Charlotte de Mouzon. As part of the study, de Mouzon went into a room of cats and tried to interact with them in different ways: call by name, hold out a hand, smile, or do nothing. It turned out that cats respond best to people if they give vocal and visual signals at the same time. Nevertheless, the seals reacted faster to the visual signals that surprised the scientists, because they were sure that the animals perceive the voice messages better. Cats were more annoyed, if ignored at all - this was noticeable in the movements of the tail, which in them, unlike dogs, means stress or discomfort. To please your cat, you need to: pronounce his name; look straight into the eyes; blink slowly. ... >>

Microphones inspired by insects 09.05.2023

What can an insect hear? Oddly enough, quite a lot. Although they are small and simple, their auditory systems are very effective. For example, with a membrane only 2 millimeters across, the Desert Locust can decompose frequencies comparable to human capabilities. By understanding how insects perceive sound and using 3D printing technology to create special materials, miniature microphones inspired by biotechnology can be designed. Andrew Reid from the University of Strathclyde in the UK presented his work on microphones that can autonomously collect acoustic data with low power consumption. His presentation "Unnatural Hearing - 3D Printing of Functional Polymers as a Pathway to Biotechnology-Inspired Microphone Design" took place on Wednesday, May 10, as part of the 184th Acoustic Society of America meeting. "Insect ears are ideal templates for reducing energy and data costs, reducing the size of sensors, and eliminating ... >>

Headphones Fairphone XL 08.05.2023

Austrian scientists have found that women report less pain when men take part in the test. In a new study, scientists have determined how gender stereotypes affect self-determination of pain levels. Male and female participants rated pain experienced with heat, pressure, studs, and high-frequency electrical stimulation. A team of male or female experimenters applied stimuli, and then the researchers analyzed how their gender affected pain scores. Evidence suggests that women are more likely to catastrophize pain. However, this moment was present only if the experimenter was a woman. Before men, women reported lower levels of pain. ... >>

Waste water beer 07.05.2023

California-based recycling company Epic Cleantec has created beer from wastewater. The drink was made from water from the laundry, showers and sinks of a 40-story building in San Francisco. In the US state of California, water recycling has become a pressing issue after years of drought. In this way, Epic Cleantec has shown how drought can be combated by converting water into drinking products. Epic OneWater Brew was created in collaboration with Brovary Devil's Canyon Brewing Company. In San Francisco, water was collected and purified using special equipment. After purification, this water is useful for reuse, but not for drinking. Epic Cleantec received positive feedback from other tasters as well. “I think a lot of people were obviously skeptical about the project at first or were hesitant to try the beer. But I would say that 99% of those who came with a little apprehension were delighted after they tried it,” says the teacher. ... >>

Fish fillet from a 3D printer 05.05.2023

Israeli company Steakholder Foods has 3D printed an edible fish fillet. Previously, they gave mankind lab-grown steaks, pieces of beef and much more in the same way. The 3D-printed sea bass fillet hasn't hit the market yet, but it could be soon. Scientists note that cultured natural sea bass cells were used for printing, and then included in bio-ink for XNUMXD printing. Fish fillet can be consumed immediately after printing, and its taste is not inferior to natural. However, it is indeed a real sea bass fillet, since natural cells were used for printing. The fillet was tasted at the Steakholder territory, where the guests of the event were treated to dishes of Israeli and Singaporean cuisine. It just melts in your mouth and crumbles into particles like a real fish. ... >>

Electric capsule to stimulate the stomach and improve appetite 05.05.2023

American engineers have created a capsule that, when swallowed, electrically stimulates the cells of the stomach, prompting them to produce the hunger hormone ghrelin. The first trials of the invention, which may help in the treatment of nausea and decreased appetite, were carried out on pigs. The hormone ghrelin is responsible for the feeling of hunger and is known for its ability to increase appetite and counteract nausea. It is produced primarily by cells in the stomach, which is why MIT scientists have hypothesized that electrically stimulating the stomach from within can increase production of the hormone. This would be useful in the treatment of conditions accompanied by poor appetite and nausea in humans. To avoid implanting electrodes in the organ, the scientists created a prototype capsule that can be swallowed like a regular tablet and will temporarily act in the stomach until it naturally leaves it. It has electronics in its structure that generates electrical signals and sends them to cells through ... >>

Gravitational wave detector 04.05.2023

The Government of India has approved the construction of its own gravitational wave detector. The object will be built according to the project of the American detector LIGO, which in 2015 was the first to detect gravitational waves, envisaged by Einstein 100 years ago. The Indian LIGO detector will close the blind spots for gravitational observations in the sky and generally increase the accuracy of localizing events in the Universe by an international network of detectors. The Indian authorities will allocate about $320 million for the project. Construction is planned near the city of Aundha in the state of Maharashtra. It will be a complex of buildings, including an L-shaped interferometer with 4 km arms. Building designs have already been completed, roads to the facility have been laid out, and part of the equipment - vacuum chambers - has been tested in the laboratory. Since the LIGO-India project will become a copy of the LIGO-USA project, the parties have probably agreed on the transfer of technology and project documentation. India should just stick to proven guidelines and repeat already ... >>

Jellyfish robots to clean up the oceans of debris 02.05.2023

Scientists within cybernetics are often inspired by creatures of nature. So this time, inventors from the Institute of Physics of the Max Planck Society (Germany) hit me with jellyfish. The result of this inspiration is a jellyfish robot that can remove debris from delicate ocean environments like coral reefs. The new works are no bigger than the palm of a hand and consist of six actuators filled with artificial muscles. These muscles are filled with oil sacs covered with electrodes, and when current is applied they receive a positive charge. They then discharge current into the surrounding negatively charged water, causing the oil in the sacs to move around and cause the robots to oscillate. This whole process creates a plunger-like flow in the water and lifts up small particles picked up by the robot. Thanks to this, the robotic jellyfish is not only able to collect garbage and filter water, but is also able to capture small biological samples such as fish eggs. However, the mechanism is not ... >>

The fabric of the future is changing shape and color 02.05.2023

Scientists from the University of Waterloo have unveiled a smart fabric that can change shape and color at the same time. It was created by interweaving several durable structures. This allows it to be strong, flexible, yet soft to the touch. If you heat the development with a hair dryer or any other device, it will change color from purple to blue. The main rule is to get in the temperature range from 20 °C to 60 °C. Otherwise, "magic" will not happen. When the fabric cools down, it will return to its original purple color. So far, this option only works with two colors, but later the palette can be expanded. Another development feature is shape change. Under the influence of electrical impulses, the tissue straightens or, conversely, contracts. It can become softer and more flexible, or it can become so rigid that it becomes difficult to bend. The fabric was woven using a device that looks like a traditional loom. Polyethylene terephthalate was used as the material ... >>

Oxygen from moon dust 01.05.2023

A team of researchers was able to extract oxygen from a model of lunar dust. In the future, they hope, this will help the colonizers of the moon. The experiment was conducted at the Johnson Space Center in Houston. Scientists knew that the soil on the moon contained compounds that could be used to produce oxygen through solar radiation. To test this, they created a model of fine-grained soil that mimics the material that covers the Moon's surface. Using a powerful lens-like laser, the team melted down a simulated lunar soil. Carbon monoxide and oxygen were found in the resulting sample. Aaron Paz, NASA senior engineer and project leader, said: "This technology can produce huge amounts of oxygen on the surface of the moon, which will provide a sustainable human presence and a monthly economy." ... >>

Monkeys are capable of long reflections 30.04.2023

A study by neuroscientists at the University of Pittsburgh showed that monkeys, like humans, are capable of long-term thinking and careful choice of decisions. A few decades ago, Nobel Prize winner Daniel Kahneman revolutionized the field of behavioral economics with his proposition theory. In his book Thinking Fast and Slow, he suggested that people use two different systems of thinking: one is almost instantaneous, which occurs automatically, and the other is conscious-logical, requiring great time and mental effort. Kahneman called the first type of thinking "fast" and the second - "slow". Slow, expensive thinking allows us to compose music, build scientific hypotheses, or balance the balance sheet. Neuroscientists challenged two rhesus monkeys with a combinatorial optimization problem. This is the "knapsack problem". It is formulated like this. There is a knapsack (or box) and a certain number of items that need to be placed in the knapsack ... >>

BeerBots mini-robots to speed up beer fermentation 30.04.2023

Scientists have developed BeerBots magnetic capsules that can move on their own. They will help speed up the beer fermentation process and eliminate the need to filter the drink. Scientist Martin Pumera and his colleagues invented self-propelled bots that actively move in beer and contribute to faster fermentation. The BeerBot capsules are 2mm in diameter and are infused with yeast, iron oxide nanoparticles, algae sodium alginate, and a ferric chloride solution. "It turned out that balls containing yeast can ferment sugar and produce carbon dioxide bubbles that push them up," ACS quoted the scientists as saying. Rising to the surface, the mini-works release carbon dioxide into the air, and then sink again, and so many times. The experiment showed that BeerBots transform sugars faster than free yeast cells, which will help change the brewing industry. ... >>

Growing hummus in space 26.04.2023

A year after the CEO of the Israeli company Aviv Labs announced a successful experiment on sprouting hummus in space, preparations were announced to continue the experiment, but on the moon. It is expected that the experiment on the Earth satellite will begin in 2025. In April last year, Dr. Jonathan Weintraub, CEO of Aviv Labs, announced that the International Space Station had successfully completed an experiment to grow chickpeas under conditions of weightlessness and lack of sunlight. 28 seeds of a special selected variety were placed in a special box with hydroponics, of which 26 seeds germinated. Weintraub then reported that the results of the experiment were amazing - the grains gave roots faster than under terrestrial conditions. Israeli scientists believe that the results of these experiments will help provide food for future space colonies on the Moon and Mars. Dr. Jonathan Weintraub was one of the founders of the SpaceIL association, which was responsible for launching the apparatus to the Moon. ... >>

Nanowire networks learn and remember like the human brain 25.04.2023

An international team of scientists led by the University of Sydney tested the ability of a nanowire network to perform complex cognitive tasks that are characteristic of a complex nervous system. The analysis showed that networks that mimic the physical structure of the brain can learn and remember data. To test their network, the scientists used a modified analog of the n-back problem. This is a popular experiment used in neurophysiology and psychology to evaluate memory. During the test, the subject, who is presented with a series of images (visual test) or names objects (hearing test), must indicate when this or that object was encountered n-steps ago. For example, such a task may involve demonstrating a sequence of letters, and the person should be told when the same letter was encountered 1, 2, or more steps ago. The average score for most people in such a task is 7. This means that most people can recognize the same image that appeared ... >>

Portable Vaccine Patch Printer 25.04.2023

Researchers from the Massachusetts Institute of Technology have found a solution to vaccinate residents of remote regions and countries with underdeveloped infrastructure. The engineer-designed printer creates vaccine-filled patches with microneedles. They can be stored for a long time at room temperature and can be easily applied to the skin when needed. Instead of producing traditional injectable vaccines, the researchers printed thumbnail-sized patches containing hundreds of microneedles. When the patch is applied to the skin, the tips of the needles dissolve under the skin, releasing the drug. For printing, the researchers use inks that include vaccine RNA molecules encapsulated in lipid nanoparticles. "Ink" also contains polymers that can be easily shaped. They tested different options and showed that an equal ratio of polyvinylpyrrolidone and polyvinyl alcohol provided the best combination of stiffness and stability. Polymers and nanocha ... >>

Solar reactor produces hydrogen and captures waste 24.04.2023

EPFL engineers have built and tested a solar reactor that can generate hydrogen from sunlight and water. The system is not only highly efficient in producing hydrogen, but also captures oxygen and heat waste to also be used. Hydrogen is set to become a key player in renewable energy, and one of the most efficient ways to produce it is to break down water into its constituent molecules. When this process is carried out using solar energy, it is called artificial photosynthesis, and this is the process that the new reactor uses. The EPFL reactor looks like a satellite dish, and it works on a similar principle - a large curved surface collects as much light as possible and concentrates it on a small device suspended in the middle. In this case, the dish collects heat from the Sun and focuses it about 800 times on the photoelectrochemical reactor. Water is pumped into this reactor, where solar energy is used to power the ... >>

Single-layer graphene demonstrates giant magnetoresistance 24.04.2023

A team of physicists found in samples of single-layer graphene manifestations of giant magnetoresistance - the phenomenon of a change in electrical resistance when it enters a magnetic field. Graphene showed an increase in resistance with magnetic field induction by several hundred percent, although the resistance had a different character in weak and strong magnetic fields. By changing electrical resistance in response to an applied magnetic field, materials exhibit the phenomenon of magnetoresistance. It arises as a result of the curvature of the trajectories of current carriers in the material under the influence of a magnetic field. One manifestation of this phenomenon is the giant magnetoresistance. It was found in multilayer magnetic materials, in which ferromagnetic layers were separated by non-magnetic layers a few nanometers wide, which led to a significant decrease in electrical resistance. The effect turned out to be much larger than the manifestations of magnetoresistance known at that time, and therefore it was called "giant magnetoresistance". ... >>

Centennial battery on bacteria 23.04.2023

Scientists have developed a battery that uses spore-forming bacteria to generate electricity. Engineers at Binghamton University have used spore-forming bacteria to create a bio-battery that can be stored for long periods of time and will potentially work even after 100 years. The coin-sized fuel cell was sealed with a piece of Kapton tape, a material that can withstand high and low temperatures. This made it possible to preserve the material for long-term storage. When the tape was removed and moisture got inside, the bacteria mixed with a chemical germ that stimulated the microbes to produce spores. The energy of biochemical reactions was enough to power an LED, a digital thermometer, or a small clock. The researchers also found that thermal activation of bacterial spores reduced the time to reach full power from 1 hour to 20 minutes, and increased humidity increased electrical output. After a week of storage ... >>

Reality alteration and false memory 23.04.2023

According to a study by specialists from the University of Amsterdam (Netherlands), the brain only needs a few seconds to change reality and create a false memory. Scientists conducted a study involving 534 volunteers. They were all shown random sequences of letters in the alphabet, some of which were mirrored (for example, instead of C). Half a second after the slide was shown, almost 20% of the participants formed an illusory memory of what they saw. And in three seconds, the percentage of those who had an erroneous memory increased to 30%. When letters appeared mirrored and misspelled, people were more likely to remember the pseudo-signature as real and not perceive the difference. This experience indicates that the memory is formed in such a way as to mention what is desired, and not what is seen. For this reason, we may interpret experiences differently and deliberately deceive ourselves and others. This phenomenon is known as the "smear theory". According to her, our memories are a synthesis of two parts: real ... >>

Men are more obese than women 22.04.2023

Scientists at the Federico II University of Naples (Italy) analyzed 43 studies of food preferences depending on gender and age. All of them were carried out in the last ten years. It turned out that women eat more carbohydrates, fruits and vegetables and less fat than men who are prone to meat and salty foods. “It appears that estrogens act on the nuclei of the hypothalamus, which control the centers of hunger and satiety. This stimulates appetite and makes women crave carbohydrate-rich foods. In men, testosterone activates a different system, namely dopamine, a neurotransmitter in the brain. It causes a feeling of strength and anger. This explains the craving for meat and salty foods, the consumption of which is associated with obesity," explained Annamaria Colao, president of the Italian Society of Endocrinology (SIE), according to the ANSA news agency. The study was presented at the first National Congress on Gender Endocrinology. ... >>

Efficient vertical solar systems for parking lots 22.04.2023

German module maker Luxor Solar and Japanese AirWater sell vertical PV systems for parking areas that can reportedly provide the same power consumption as conventional PV carports but take up less space. Japanese medical equipment supplier AirWater and Luxor Solar KK, the Japanese division of German solar module manufacturer Luxor Solar GmbH, have developed a new vertical photovoltaic system for urban areas. "Our system can be deployed in parking lots without reducing the capacity of parking spaces," said Uwe Liebscher, CEO of Luxor Solar KK. "The height from the ground to the bottom of the module is over 2 meters. It provides electrical safety due to its height, and also offers a safer solution for drivers by requiring minimal space on the ground." The two companies claim the system is ideal for areas with heavy snowfall. " ... >>

Keyboard and mouse are the best indicators of stress 21.04.2023

Scientists at the Swiss Federal Institute of Technology in Zurich (ETHZ) have conducted a new large-scale study, the results of which show that exactly how we interact with the keyboard and mouse can tell a lot about our stress levels. Moreover, the researchers believe that this method is even more effective than tracking heart rate. At the first stage, scientists conducted a study in which 90 people took part. They were asked to perform simple office tasks such as scheduling appointments, recording data, and doing data analysis. The participants were also divided into two groups - some worked unhindered, while others were distracted by chat messages or asked to interrupt for meetings. During the study, the scientists also observed the behavior of the recipients - recorded their interaction with the mouse and keyboard, tracked their heart rate, and also asked how tense they were. Later, scientists used the obtained data and machine ... >>

Language Model Dolly 2.0 21.04.2023

US enterprise software company Databricks has released Dolly 2.0, the next version of its Large Language Model (LLM), with ChatGPT-like features. It is the first open source LLM with a free learning instruction set that will help companies use AI technology for their own commercial projects - without having to pay for APIs or share data with third parties. In recent months, many language models have been released, similar to OpenAI's GPT, which by many definitions could be considered open. One of these is Meta's LLaMA, which in turn was inspired by Alpaca, Koala, Vicuna, and Dolly 1.0. However, many of these "open" models were under the control of systems developers - for example, the Stanford team's Alpaca AI project, which was trained based on GPT-3.5 instructions and based on LLaMA 7B. The OpenAI terms of use include a rule that researchers cannot use the products ... >>

Gravity can create light 20.04.2023

Work from Swinburne University of Technology showed that under the exotic conditions of the early universe, gravitational waves could perturb space-time so violently that they spontaneously produced light. When you sit on a swing and want to swing harder, you start moving your legs back and forth. You quickly find the right rhythm to swing at the right moment. This special kind of phenomenon is known in physics as parametric resonance. When your legs move at the resonant frequency of the system, they can transfer energy to the system, causing the swing to rise higher. These kinds of resonances are found everywhere, and a team of researchers found that an exotic form of parametric resonance could have originated in the very early universe. Perhaps one of the most important phenomena in the entire history of the universe was inflation. This is a hypothetical event that happened when our universe was less than a second. During inflation, the cosmos expanded to about ... >>

Charging cable Phoenix Contact 375 kW 20.04.2023

Phoenix Contact has unveiled its new HPC charging cable from the Charx Connect Professional family, which is said to provide safe, high power charging with a constant output of 375kW and does not require cooling. Fast charging cables in this performance class are usually liquid-cooled, which increases the cost of the cables themselves and the required cooling unit. Until now, however, manufacturers have relied on cooling as it allows for a lower conductor cross-section and for the end user to easily move the CCS cable in the charging station. Although Phoenix Contact has increased the conductor cross section to 4x 50 square millimetres, the company believes that the cost advantages and the elimination of a liquid-cooled cooling jacket offset the larger conductor cross section. Uncooled charging cables must operate "permanently and safely" at 375 amps, even at temperatures ... >>

Cats understand their owners 19.04.2023

Many pet owners believe that their pets understand everything that is said to them. And scientists from Sophia University in Tokyo have found evidence that cats can actually understand human language. The researchers studied the behavior of 78 cats and found that cats can distinguish their nickname from other words, even if it is pronounced with an accent. They are able to match words with individual objects, which indicates a high understanding of the language. However, scientists also note that these skills depend on the individual characteristics of each feline personality and its level of intelligence. Even among cats, there can be disagreement about the ability to understand human language. Domestic cats are also very good at reading the mood of their owner and behave accordingly. They may be cautious in communication or try to fawn. It may seem that the cat perfectly understands what is being said to him. In addition, cats also understand that small children do not always understand the message. ... >>

Updated EU requirements for power consumption of appliances in sleep mode 18.04.2023

The European Commission has adopted new rules to reduce the energy consumption of such electrical appliances when they are in "standby" mode. The EU regulation establishing standby and off-state power consumption requirements for electrical and electronic household and office equipment was first approved in 2008. It was last updated ten years ago. The European Commission has not changed the energy consumption limits, but has expanded the list of devices to which they must apply. For example, eco-design requirements now extend to appliances with an external low-voltage power source, such as small network equipment (including Wi-Fi routers and modems) or wireless speakers. The limits are set to 0,5W in idle or off mode, or 1W if they continue to display information in idle mode. For devices connected to the Internet in standby mode, the limit is set at 2 to 8 V ... >>

Apple to switch to recycled cobalt, gold, tin and rare earths 18.04.2023

By 2025, Apple has committed to using 100% recycled cobalt in all of its batteries. The company also plans to completely switch to recycled rare earth elements in magnets, and transfer all boards of its own production to recycled gold and tin. Last year, Apple only used 25% recycled cobalt. Although there is a positive trend compared to 13% in 2021, the 2025 target looks quite ambitious. The company already uses 73% recycled rare earths and 38% recycled tin. Ultimately, the company hopes to make all products exclusively from recycled and renewable materials. Its products are expected to be carbon neutral by 2030. A year ago, only 20% of the materials in Apple hardware were recycled or upgraded. Undoubtedly, such statements are partly related to the formation of the company's image. However, cobalt savings may be more important, other claims ... >>

hangover cure 17.04.2023

Chinese scientists have created cures for hangovers. They are based on beneficial bacteria that break down alcohol in the liver. The researchers tested this remedy on mice. Before testing the probiotic, they recorded how long it took drunk mice to recover on their own, this parameter was 6-10 hours. The study showed that mice given the probiotic regained exercise capacity after 5,5 hours. Mice not taking the probiotic took about 6,4 hours. This drug not only reduced the amount of alcohol absorbed by the body, but also increased the length of time that the body tolerates alcohol, and also reduced the recovery time after acute alcohol poisoning. ... >>

Tiny chip that controls multiple laser beams 17.04.2023

Engineers at the US National Institute of Standards and Technology have developed chip-scale devices to simultaneously control the color, focus, direction of movement, and polarization of multiple beams of laser light. The development is suitable for creating portable sensors and quantum devices. Traditional optical systems, which allow even a single laser beam to be controlled, represent a large-scale structure the size of a dining table. It houses many lenses, polarizers, mirrors and other devices. To create portable sensors and quantum computers will require miniature chips. The researchers combined two technologies at the chip level: photonic integrated circuits, using tiny transparent channels and other micro-components for light; and a source of unconventional optics known as the optical metasurface. Such surfaces consist of glass plates with millions of tiny structures only a few hundred billionths of a meter high, which ... >>

Replacement of experimental animals with organelles 16.04.2023

Organoid technology can reduce the need for animal testing in vaccine development by allowing large numbers of antigens to be screened at a lower cost. B cell-producing organelles are perhaps the hottest topic today when it comes to screening vaccine candidates for rabbit fever, also known as tularemia. This exciting development is a step towards the long-awaited goal of replacing animals for vaccine testing before clinical trials. Animal testing has been the subject of controversy over the years, with animal rights and environmental activists leading the fight against this controversial practice. But it seems that with the help of organoids, the need for animal testing may soon become a thing of the past. Organelles are collections of cells that behave like real organs. They are grown in the laboratory and kept alive in conditions that mimic the body's natural environment. Although before the use of organoids instead of transplants ... >>

JUICE space probe 14.04.2023

The European Space Agency launched an Ariane 5 rocket from Kourou, French Guiana. Thus, the mission to explore the satellites of Jupiter was launched. The rocket launched the 6-ton Jupiter Ice Moons Explorer (JUICE) spacecraft into space. This is ESA's largest deep space mission. The spacecraft was built by Airbus Defense & Space at a cost of 1,5 billion euros. The idea for the JUICE mission came about after NASA's Galileo and Cassini probes discovered that some moons of Jupiter and Saturn were covered in ice. They likely also contain large subsurface oceans in which microbial life can exist. "The next logical step was to return to Jupiter with improved equipment to study these oceans in detail," said Nicolas Altobelli, a planetary scientist at the European Space Agency who helped develop the JUICE mission. "And with that in mind, we wanted to see if they were possible habitats. ... >>

Electrically conductive gel could help create flexible robots 14.04.2023

Engineers at Carnegie Mellon University have succeeded in combining polymers with liquid metal to develop an organogel composite that is ultra-flexible and highly conductive. Thanks to the new gel, scientists may be on their way to creating the first truly "soft" robots and self-healing biometric devices. According to the creators, their material is soft and very elastic, with a deformation limit of more than 400%. To create a composite, the original polymer was immersed in a solvent to achieve plasticity. The resulting polymer base was then mixed with microscopic droplets of a liquid gallium-indium alloy and silver flakes. The end product was a low-density gel-like substance containing enough metal to transmit electricity. The torn piece of the composite can be reattached, after which it will restore its shape. Its electrical conductivity is superior to that of any other elastic material, making it possible to connect electrical ... >>

Low temperatures can increase lifespan 13.04.2023

Cold temperatures have long been associated with various health benefits, including increased life expectancy. According to a recent study, people living in cold climates tend to live longer than those living in warm regions. This surprising finding has sparked great interest among both scientists and health experts seeking to uncover the mysterious link between cold temperatures and longevity. The study in question, conducted by a team of scientists from the University of Michigan, analyzed data from more than 3 million people from around the world. Researchers have found that people living in cold regions tend to have longer lives than those living in warm regions. In particular, for every 1 degree Celsius drop in temperature, there was a corresponding 1% drop in mortality. Although the exact causes of this phenomenon are not yet fully understood, there are several theories put forward ... >>

Agricultural sequestration to overcome the climate crisis 12.04.2023

A group of scientists from Berkeley presented a study that will help to forget about the climate crisis quickly and relatively cheaply. Experts suggest growing crops that naturally suck excess carbon out of the air and then bury harvested vegetation in the ground in bioengineered landfills kept dry with salts. This is a new look at an existing process called agrosequestration. The researchers argue that if implemented on a large enough scale, the consequences can be impressive. Plus, at a price equivalent to only 53 cents a gallon of gasoline, it's still a very good deal. "We argue that proper engineering can 100% solve the climate crisis at an affordable cost. If implemented on a global scale, this method of carbon sequestration has the potential to eliminate current annual carbon dioxide emissions, as well as previous years' emissions from the atmosphere," he said. lead author of the study ... >>

edible battery 12.04.2023

Scientists continue to develop electronics that can safely monitor and heal our health inside the body. Unfortunately, powering these tiny medical gadgets isn't always easy. Now there is a new type of battery that can help in this department. Made from completely edible substances, it can safely dissolve in the stomach, doing whatever it needs. The prototype device, developed by molecular electronics experts at the Italian Institute of Technology, operates at a harmless voltage of 0,65 volts and delivers 48 microamps for 12 minutes, in the range needed to power tiny electronics. Made from a varied list of ingredients, this is the first functional rechargeable battery to be served as a snack.

Liquid with piezoelectric effect 11.04.2023

American scientists have discovered a liquid that turns mechanical force into an electrical charge. Michigan State University researchers have described the first known liquid to act as a piezoelectric material. It converts pressure into electricity and vice versa. It was believed that only rigid bodies possess such properties. The discovery may create a new direction in optics and hydraulics. Physicists have found extraordinary characteristics by working with ionic liquids. These are salts that remain liquid at unusually low temperatures (the lower boiling point of water). Composed only of positively and negatively charged ions, the material is a viscous structure that resembles machine oil or maple syrup. The study showed that when ionic liquids were placed in a cylinder and compressed by a piston, they generated electricity proportional to the applied force. Scientists also found the opposite effect: the optical properties of ionic liquids changed under the influence of ... >>

Found the optimal distance between the rows of potatoes 11.04.2023

Mark Pavek, a professor and potato specialist at the University of Washington (USA), has proven over many years of experience that the optimal row spacing for potatoes in the Columbia River Basin is 76,2-81,28 cm. The usual traditional row width is from 34 to 36 inches (86,36-91,44 cm) in the northwestern United States. But farmers are in no hurry to switch to narrower row spacings, as money has already been invested in machines adapted for wider row spacings. In addition, they look at the experience of neighbors. Although the transition to narrower row spacing has been measured in years, there have been some recent changes for growers in the Columbia Basin (British Columbia, Washington and Oregon). More manufacturers have made the transition from 34" to 32" rows. Pavek said these growers are able to make more money over time despite increasing seed costs to plant in tighter rows. research ... >>

Plastic transistor amplifies biochemical signal 10.04.2023

The molecules in our body are constantly communicating. Some of these molecules provide a biochemical fingerprint that can indicate how a wound is healing, whether a cancer treatment is working or not, or whether a virus has invaded the body. If we could sense these signals in real time with high sensitivity, then we could recognize health problems faster and monitor disease progression. Now researchers at Northwestern University have developed a new technology that makes it easier to eavesdrop on our body's internal conversations. Although the body's chemical signals are incredibly weak, making them difficult to detect and analyze, scientists have developed a new method that amplifies the signals by more than 1000 times. Transistors, the building block of electronics, can amplify weak signals to provide amplified output. The new approach simplifies signal detection without complex and cumbersome electronics. By providing amplification of weak biochemical signals, the new approach does ... >>

World's deepest fish discovered 10.04.2023

In the Izu-Ogasawara Trench, south of Japan, at a depth of 8336 km, scientists discovered a snailfish that is now considered the deepest-sea fish in the world. According to lead scientist Prof. Alan Jamison, the snailfish can be found at the deepest depth any fish can survive, and this is likely due to the warm waters of a trough located in the Pacific Ocean. It was not possible to catch a fish to determine its species type, however, earlier similar individuals were caught at a depth of 8022 meters. “We foresaw that there would be the deepest-sea fish, and we foresaw that it would be a snail fish. I get upset when they tell me that we don’t know anything about the sea depths. We are working. Everything changes very quickly,” the scientist noted . To this day, a depth of 8178 meters was the record for living creatures. Researchers have discovered fish south of the Pacific Ocean in the Mariana Trench. Now in the oceans there are more than 300 different species of snail fish. They are similar in shape to ... >>

Fully autonomous shuttle 09.04.2023

The RLV LEX shuttle can take off and land completely independently, and its design is reminiscent of past developments of many years ago. The Indian Space Research Organization (ISRO) has announced the successful test of an autonomous reusable shuttle, The Register reports. This peculiar space plane, as conceived by the developers, plays a key role in reducing the cost of delivering cargo to low Earth orbit for use at space stations. ISRO lifted the multiple launch vehicle to a height of 4,5 km using a helicopter, and then experts watched the RLV LEX perform a steep landing event at that height. This fully autonomous shuttle is designed to launch a rocket into orbit, deploy a payload, and then return to Earth and land on a runway. Externally, the ship is very similar to the previous developments of the Americans and the repeated Soviet ship "Buran". RLV LEX is currently chi ... >>

The Greenland ice sheet is melting catastrophically 08.04.2023

Scientists are becoming increasingly concerned about tipping points for climate change. In a new study, they identified two such tipping points for the melting of the 1,7 million square kilometer Greenland ice sheet and the second largest ice storage after Antarctica. According to scientists' simulations, the release of 1000 gigatonnes of carbon into the atmosphere will lead to the complete melting of the southern part of the ice sheet. With emissions of 2500 gigatons, the entire ice sheet will melt irrevocably. Since human activity began to noticeably affect the climate, 500 gigatonnes of carbon have been released into the atmosphere. This means that we are already halfway to losing a large number of the Greenland ice sheet. "The first point of no return is not far from today's climate conditions, so we run the risk of crossing it. Once we start sliding, we will fall off this cliff and will not be able to climb back," said climate scientist Dennis Henning from the Potsdam Institute for Climate Research in Germany. ... >>

Audfly Focusound glass speaker with directional sound 07.04.2023

Hong Kong-based electronic acoustic solutions company Audfly has been working on glass for directional sound transmission since 2019. However, only now the company has announced its intention to release a finished product by presenting the Focusound solution on the Kickstarter platform. The novelty is positioned as a substitute for headphones - the speaker directs the sound exactly to the user. The use of ultrasound for directional sound transmission is not really a new idea. Technologies for immersing in a user's personal "sound bubble" without disturbing others present in the room have been invented for a long time - in theory, this allows you to do without headphones. However, Audfly claims to be the only one to have built the first device of its kind using clear glass. The result of several years of research and development is a speaker made of a laminated glass panel, which in turn consists of many small "vibrations". ... >>

sunny pavement 06.04.2023

The Hungarian company Platio has developed a damage-resistant solar tile walkway. A 400 square meter solar walkway was recently installed in Groningen, the Netherlands, as part of the European Union's "Making City" project. "Our patented technology has been designed so that micro-cracks do not appear in the solar cell and do not affect performance," a Platio spokesman said when asked about mechanical stress.

Getting electricity from blood sugar 06.04.2023

A team of researchers from the ETH Zurich has created a device that converts excess glucose in human blood into electricity. It can be used to power pacemakers and more. A group of researchers led by Martin Fussenegger from the Department of Biosystems Science and Engineering at the ETH Zurich in Basel has turned a seemingly futuristic idea into reality. They developed an implanted fuel cell that uses excess blood sugar (glucose) from tissues to generate electrical energy. The researchers combined the fuel cell with artificial beta foci developed by their group several years ago. They produce insulin at the touch of a button and effectively lower blood glucose levels by working like their natural counterpart in the pancreas. Many people, especially in the industrialized Western countries, consume more carbohydrates than they need in their daily lives," Fussenegg explains. ... >>

The science of petting a cat 05.04.2023

Scientists have figured out how to properly stroke cats so that they like it. According to Dr Lauren Fink, an expert at Nottingham Trent University, there is a right way and a wrong way to pet a cat, and if you do it wrong it can be dangerous. While most people think that cats love to be stroked, it really depends on each individual animal. Experts advise starting by stroking the cat's head and neck, and then moving on to the chest and back. It is also important to monitor the reaction of the cat - if she starts wagging her tail, then this means that she does not want to be stroked and she needs to be left alone. Experts also warn of the dangers of stroking a cat's belly, as it can lead to a seizure. Instead, they advise petting cats only on the back. Experts also note that improper petting of a cat can lead to injury to the animal. For example, if you stroke a cat against the coat, it can be painful for her. Poeto ... >>

Space water engine 05.04.2023

Pale Blue, who was born in the walls of the University of Tokyo, tested the rocket engine while adjusting the orbit of the EYE satellite. Despite the simple mechanics of operation based on Newtonian physics, and relatively low cost, water engines for satellites have not yet become widespread. Developed by Pale Blue, the system was launched with Sony's EYE satellite as part of its Earth imaging program. At launch, the engine was turned on for approximately two minutes, during which the EYE satellite orbit was corrected. Pale Blue was created by Japanese scientists three years ago. It is developing several types of water-based propulsion systems. The one that was launched on EYE is called "Resistojet". The principle of its operation is quite simple. Basically, it just pushes the water out of the tube to push the satellite in a given direction. Correction of the movement of the object in this case is carried out using electronics. The company is not going to stop there. She ... >>

The lightest paint ever developed 04.04.2023

Canadian scientists have developed the world's lightest paint, which weighs just 2,5 nanograms per square centimeter and can cover a surface the size of a Boeing 747 with about 3 kilograms of paint. This innovative product has potential applications in a variety of industries, including aerospace, where it could help reduce aircraft weight and ultimately reduce fuel consumption. The new paint was created by researchers at the University of Toronto and consists of hollow silica nanoparticles that are incredibly small and light and can scatter light in a way that reflects a particular color. The particles are suspended in a liquid that can be easily sawn into the surface. The unique properties of this paint set it apart from traditional colors that rely on pigments to create colors. The hollow silica nanoparticles in the new paint do not absorb light, but rather reflect it, creating the desired color. This makes the paint incredibly light, but very ... >>

Fossilized unicellular can help find methane in the ocean 04.04.2023

A research team led by a Brown University scientist has discovered a new way to track the transformation of deep-sea methane deposits into a gas previously invisible to researchers. In this they were helped by benthic foraminifers - unicellular organisms from the order Miliolida. Scientists have found that these organisms act as a so-called indicator when it comes to the process of dissociation of methane hydrate. Deep sea methane deposits are deposits in the form of ice under the seafloor. The process of converting ice-like methane into gas rising to the surface is called methane hydrate dissociation. And the fossilized shells of the single-celled organisms Miliolida, in fact, act as indicators of the places where this process occurs, even when the amount of gas released is extremely small. In the course of the study, scientists studied nearly 400 individual Miliolida fossils that witnessed previously unrecorded events of the transformation of capitalization ... >>

The effect of cocoa on mental performance 03.04.2023

Scientists have found out the effect of cocoa on mental performance. The study involved healthy men from 18 to 40 years old. How cocoa activates the brain, said British scientists from the University of Birmingham and American colleagues from the University of Illinois. It turned out that cocoa antioxidants have such an effect. Flavanols have a beneficial effect on the functioning of small blood vessels in the brain. In their experiments, scientists moved away from sterility and tried to reproduce the average environmental background. After a cup of cocoa, the participants in the experiment breathed air with an excess of carbon dioxide. Despite the lack of oxygen, those men who had cocoa with flavanols performed 11% faster than those who got cocoa with low levels of antioxidants on savvy tasks. And the level of maximum supply of oxygen to the brain was almost three times higher. The researchers concluded that cocoa - even in a drink, even in dark chocolate - helps blood ... >>

The world's oceans accumulate mercury and release it into the atmosphere 02.04.2023

A new study has shown that excess mercury enters the atmosphere from the oceans. The estimate of the amount of mercury in the atmosphere has been increased by 40%. Almost all mercury in nature is found in a bound form - in cinnabar. And for the dispersion of this toxic substance is mainly responsible for human activity. A group of environmental scientists working at several institutes in China and the United States, as well as one in Belgium, found that the excess amount of mercury released into the atmosphere in the global circulation comes from the oceans. Mercury is a heavy, silvery-white metal that exists in a liquid state at room temperature. It is clear that it is found in the environment and in most plants and animals. In nature, mercury is commonly found in cinnabar deposits. Thus, most of the mercury found in the environment is the result of human activities. Elevated compared to normal levels of mercury in the OR ... >>

Digital wallet instead of paper and plastic documents 02.04.2023

The European Union is developing a digital wallet that will allow you to abandon all paper and plastic documents, in particular, from an ID card or a driver's license. MEPs have been discussing a new version of the relevant regulation, known by the abbreviation eiDAS, since 2020. The relevant EU institutions have completed work on the preliminary application of the digital wallet. It is just starting to be tested. The digital wallet will be able to store proof of all permits and rights, including driver's licenses, fishing permits and prescriptions for medicines. In addition, it will allow you to choose to whom and what information to show. "For example, if a traffic policeman stops you, he really has the right to look at your personal code and name, while the doorman at the bar does not need to know where you live, what your personal code, date of birth or name. He must see that the person is over 18. That’s all the information they need,” commented ... >>

Mammoth muscle tissue grown 01.04.2023

Scientists in Japan say they have been able to grow the muscle tissue of extinct mammoths using cells obtained from a preserved sample of mammoth muscle tissue found in Siberia. This discovery opens up the possibility of creating new types of meat, in particular, mammoth meat, which disappeared more than 4000 years ago. The process of growing mammoth muscle tissue in a lab, called culture, involves scientists using cells found in mammoth muscle tissue and placing them on nutrient media that promote tissue development. Through this method, scientists were able to grow mammoth muscle tissue that can be used to create meat dishes. However, there are certain problems associated with the creation of such meat. For example, scientists cannot be completely sure that meat obtained from this method is safe to consume. Also, the absence of mammoths on Earth may raise ethical questions about the use of their meat. Growing mammoth muscle tissue in ... >>

Tram line with a section without a contact network 31.03.2023

In Warsaw, the first tram line in Poland was launched with a section without a contact network, which will be served by Hyundai trams. 30 vehicles will run on the line. A total of 123 trams have been ordered from the Korean manufacturer, 80 of which have already arrived in Warsaw. Hyundai trams use supercapacitors, that is, modern energy storage devices. It is noted that this is not a battery, but a completely different technology. The wagons can move in separate sections with lowered pantographs - without receiving electricity from the contact network. As explained in the Warsaw tram administration, part of the contact network had to be dismantled on the modernized tram line. Normally, this would have brought traffic to a halt on the site. But thanks to the new trams, it is now possible to continue transporting passengers on the route. Trams run on the line every 8 minutes during rush hour and every 12 minutes during off-peak hours. ... >>

Impact of urbanization on insects 29.03.2023

Scientists studying the effects of urbanization on insects have found that some insects are more adapted to living in urban environments than others. Amidst the hustle and bustle of urban life, there is a wide variety of creatures including insects, spiders and ants that are often overlooked but have a significant impact on urban ecosystems. A study by Austrian scientists found a link between the degree of urbanization and the prevalence of arthropod invertebrates with an exoskeleton, such as bees, insects and spiders. "We show that the richness and diversity of arthropods in trees and shrubs decreases as one moves from the countryside to the city," said first author Dr. Marion Schatlen, a research fellow at the University of Innsbruck, Austria. "In particular, we show that urbanization is unfavorable for wingless groups, especially in trees. Indeed, cobwebs and springtails are less common in the city, where, on the contrary, ... >>

Pets should not be allowed in bed 28.03.2023

Many people like to sleep with their pets, but do not suspect that this can negatively affect their health. American scientists have found that cats and dogs can cause various sleep disorders in their owners. The researchers analyzed data from people who participated in the 2005-2006 National Health and Nutrition Survey. In their work, scientists took into account such factors as sleep quality, such as fatigue, drowsiness, prolonged falling asleep or insufficient sleep. They found that dog owners were more likely to suffer from sleep disorders, and cat owners were more likely to suffer from spontaneous leg twitches. Scientists cannot say exactly why pets affect the sleep of their owners. Perhaps this is due to the fact that cats and dogs are more active at night and can interfere with a peaceful rest. However, they do not recommend that people get rid of their pupils because of this: simply denying them access to the bedroom is enough. Scientists also warn people with chronic sleep disorders that the institution ... >>

Crab shell battery anodes 27.03.2023

A group of researchers from Japan and China have proposed using crustacean shells as an alternative to lithium-ion batteries. The technology they created makes it possible to make a carbon anode for sodium-based rechargeable batteries from shells. To make their "crab carbon," the researchers heated crustacean shells to temperatures in excess of 500 degrees Celsius. After that, they added the resulting carbon to a solution of either tin sulfide or iron sulfide and then dried them to form anodes. The porous fibrous structure of crab carbon provides a huge surface area, which increases the material's conductivity and excellent sodium ion transport. Traditional modern batteries use a lithium-ion structure. It has proven itself well, but lithium is a rather rare and expensive metal. Alternatively, different laboratories are working on the production of sodium-ion batteries. Although sodium ions are chemically similar to lithium, they ... >>

Harm of burnt food 26.03.2023

Products after cooking may be slightly burnt. It is in this crust that danger lurks. Burnt food was studied by scientists from Stockholm University. At the same time, they began their research in 2002. For more than 20 years, they have collected enough information confirming the fact that such food is dangerous. Any chef will tell you that one of the main requirements in cooking is to observe the temperature regime. And it's not just about taste. For example, foods such as potatoes or bread, when heated to 120 degrees, begin to brown. This is the reaction in which acrylamide appears in the products. It is this substance that is the most dangerous carcinogen. Fatima Saleh, Associate Professor at the Department of Medical Laboratory Sciences at the University of Beirut, says that many diseases have been linked to acrylamides. It can cause cancer and dementia. It also weakens the natural immunity of a person, which makes him vulnerable to various pathogens. ... >>

Developed a chip that can withstand the cold of space 22.03.2023

New York-based quantum computing startup SEEQC has announced a digital chip that can operate at temperatures below the cold of space. This will allow it to be used with quantum processors located in cryogenic chambers. Quantum computers use the features of quantum physics to solve problems that are impossible or very difficult to solve on conventional computers. However, quantum bits or qubits, which are the main elements of quantum computers, are very sensitive to external influences and can lose their state. Therefore, they require cooling to temperatures close to absolute zero (about -273°C). To manage and control qubits, it is necessary to have a classical computer chip that can communicate with a quantum processor. However, most existing classical chips cannot operate at such low temperatures and must be placed outside the cryogenic chamber. This creates by ... >>

Growing tomatoes in air-conditioned greenhouses 22.03.2023

Emirati tomato growers are gearing up for the start of summer when they will be able to grow tomatoes in challenging conditions and temperatures as high as 45°C thanks to air-conditioned greenhouses. Ali Aljararva, CEO of Ghalya Farm, told about this. “When temperatures rise to 40-45°C in summer, no crop survives in such conditions, and all Emirati growers use greenhouses with air conditioning and cool air currents during the day,” Ali Aljararwa notes. According to the grower, the maintenance of these greenhouses is inexpensive in terms of energy, but involves the use of large amounts of water: "The cost of energy is not very high, which allows us to continue to produce tomatoes at competitive prices, and the impact on the environment is negligible." Ali Aljararwa stated that the quality of vegetables is also very similar to those produced in the open field. Now he has 10 hectares covered with greenhouses, and plans to increase this to 20 hectares in the coming seasons. All ... >>

Shadow in the car where needed 21.03.2023

Korean engineers have invented a way to distribute shadow spots throughout the interior of the vehicle, as passengers need. This will bring natural light into the cabin of the Hyundai Ioniq 6. The system uses cameras and light intensity sensors in the cabin. The task of the camera is to determine the position and movement of passengers, and the light intensity sensors determine how much light is available in different areas of the cabin. Together with the camera system, there are external sensors mounted on the roof to detect the intensity of incoming natural light as well as its orientation relative to the car. Let's assume that the available natural light will make the cabin lighter than desired. In this case, the smart lock units automatically dim to reduce. The control unit also detects the lighting around passengers and can dim some areas on the roof to keep residents cool in the shade. When working with a roof-mounted light sensor and interior ... >>

Meat steak grown from tenderloin 20.03.2023

Swiss startup Mirai Foods has unveiled the world's first cage-grown steak. The startup has been working on the creation of cultured meat for a long time. Now the company claims that they have managed to make the first real breakthrough. The technology has already received three patents and the name Fibration Technology. Mirai Food said the discovery is due to a naturally renewable cellular process that allows tissue to be grown to mimic conventional meat. "The fillet steak is the most difficult challenge: it consists of different types of cells, which, when combined correctly, lead to a complex structure of meat," says the founder of the startup. The steak was made in a bioreactor of our own design. Steak meat is made from long cultured muscle fibers, which are then combined with enzymes and supplemented with cultured adipose tissue. The process of creating meat in this way takes five days, after which "the central part of the tenderloin comes out, from which steaks of almost any thickness can be cut." ... >>

Flood protection of the Maldives 19.03.2023

To protect the Maldives from flooding, you need to increase their height in relation to sea level by six times, say scientists from the University of East Anglia. Scientists have put forward a proposal to raise the Maldives above sea level by about 6 meters in order to protect them from possible flooding due to the continuous melting of glacial masses. Embankments and the construction of new islands on the archipelago will help raise the Maldives. The state will not be able to do without such a reconstruction, according to scientists, because 80% of its coastal surface is no more than 1 meter above sea level. In order to raise every 100 hectares of the islands, you need to invest at least 8 million dollars. The Maldives has 1196 islands with a total area of ​​about 297 sq. km. A new island has already been created in the Maldives, which was named Hulhumale. It is built from sea sand. ... >>

Clean energy from the air 19.03.2023

Scientists have discovered that one of the "relatives" of the tuberculosis bacterium is an enzyme that converts hydrogen into an electric current. The researchers believe that the discovery can be used for a new way to get energy from the air. This is Mycobacterium smegmatis, a bacterium that uses the Huc enzyme to generate energy from hydrogen in the atmosphere, allowing it to survive in extreme nutrient-deficient environments. The scientists said they had discovered and studied an enzyme that could be used as a source of clean energy to power laptop computers. "We believe that a power source containing the Huc enzyme could power a range of small portable devices, including biometric sensors, environmental monitoring devices, digital clocks, calculators, and even simple computers," said study lead author Reece. Grinter, a microbiologist at Monash University in Australia. It is a fast growing non-parasitic ba ... >>

bio-cement 18.03.2023

Bioengineers from the Technical University of Denmark have figured out how to reduce carbon emissions in the construction industry. Genetically modified bacteria capture carbon dioxide and use it to create calcium carbonate, one of the main elements of cement. For their production, the researchers used the genes of coral polyps. These animals build "huge buildings" under water - coral reefs - calcareous structures that resemble cement in composition. Bioengineers have transferred genes from these living organisms to bacteria. The modified microorganisms produce an enzyme that binds carbon dioxide to calcium carbonate (limestone). High temperatures when cement is heated during the manufacturing process lead to the release of carbon dioxide. In 2021 alone, according to the authors of the study, about 2,9 billion tons of carbon dioxide were emitted into the atmosphere during the production of this building material. This is about 7% of the total emissions. The main idea of ​​the new technology ... >>

molecular switch 18.03.2023

An international team of researchers, including those from the Institute of Solid State Physics at the University of Tokyo, has made a groundbreaking discovery. They successfully demonstrated the use of a single molecule called a fullerene as a transistor-like switch. The team achieved this by applying a finely calibrated laser pulse that allowed them to predictably control the path of the input electron. The switching process provided by fullerene molecules can be significantly faster than switches used in microchips, with speed increases of three to six orders of magnitude depending on the laser pulses used. The use of fullerene switches on a network could result in a computer with capabilities beyond what is available with electronic transistors. In addition, they have the potential to revolutionize microscopic imaging devices, delivering unprecedented levels of resolution. More than 70 years ago, physics about ... >>

edible drone 17.03.2023

Scientists from the University of Electrical Communications in Japan and the Swiss Federal Polytechnic School of Lausanne are developing drones with edible parts. According to scientists, this will help deliver provisions to hard-to-reach areas during rescue operations. Researchers have developed a working prototype of a flying drone that is half made from edible materials. The wings of the robot are made of rice crackers with gelatin. Their span is 700 millimeters. In addition, the drone is capable of carrying 80 grams of water and moving at a speed of 10 meters per second. Scientists plan to develop devices in which about 75% of the parts will consist of edible elements. Thus, the drone will be able to deliver twice as much food. In addition, scientists want to create similar robots for industrial production, where there is a high probability of metal particles getting into the final products. The researchers suggest replacing the manipulators with gelatin ones. ... >>

NASA's hypersonic plane set a speed record 16.03.2023

The United States has long been a leader in the development of the fastest aircraft. In the late 1990s, the NASA X-43 was developed as part of the Hyper-X program. As part of the space agency's "better, faster, cheaper" program, Hyper-X used National Aerospace Plane technology. The purpose of the Hyper-X project was to test in flight key propulsion systems and related technologies for hypersonic aircraft. The first two X-43 test vehicles were built to fly at Mach 7, the highest speed for a jet aircraft. At that time, the third X-43 was able to reach Mach 9,6. To understand the significance of this achievement, the highest speed achieved by NASA's X-15 rocket plane during flight testing in the late 1960s was Mach 6,7. The X-43A test aircraft was an unmanned vehicle, 3,7 meters long. Its unique lifting body design provided significant lift for flight, ... >>

Makeup and pop culture made people afraid of clowns 16.03.2023

British researchers have identified the main causes of the widespread fear of clowns in the world. They called the difficulty in recognizing the emotions of a clown, which hides the pronounced makeup, as well as the portrayal of clowns as negative characters in the media. The fear of clowns is called coulrophobia, and it is common among both children and adults. One of the most comprehensive studies found that about half of the human population is afraid of clowns to some extent, and for 5 percent this fear is panic. Why characters, whose purpose is to entertain and bring joy, for a large number of people are a source of negative emotions, has not been sufficiently studied, although various hypotheses are put forward. Uncertainty motivated psychologists at the University of South Wales to conduct their own research. Scientists analyzed the existing scientific literature on the topic of coulrophobia, highlighting hypotheses for its explanation, and created their own questionnaire for ... >>

Reduction of emissions from metallurgical enterprises 15.03.2023

Scientists at the University of Birmingham in the UK have developed a low-cost process for existing steel mills that can cut emissions by about 90%. As is known, the metallurgical industry accounts for 7-9% of the world's anthropogenic greenhouse gas emissions. A modification proposed by Drs. Yulong Ding and Harriet Kildahl removes coke from the cycle by pumping CO directly into the blast furnace. This gas is produced by capturing the CO2 generated in the furnace and splitting it into CO and oxygen. Oxygen can be used in the second part of the steelmaking process when the gas is blown through the molten iron to burn off some of the carbon in the metal. The technology is based on the BCNF1 perovskite material (a mixture of barium carbonate, calcium carbonate, niobium oxide and iron oxide). When the processing system pumps CO2 through the reaction chamber, BCNF1 captures oxygen atoms from the gas and absorbs them ... >>

The future can influence the past 15.03.2023

In 2022, the Nobel Prize in Physics was awarded for experimental work that showed that the quantum world must break some of our fundamental ideas about how the universe works. In the published article there is a statement that in order to preserve modern physics, science must admit the possibility of the influence of the future on the past. It may seem unusual, but in fact, scientists have been considering such an idea for a long time. In modern physics, in particular in quantum mechanics, there are several strange phenomena that cannot be explained by ordinary physical laws. One of them is the measurement delay effect, when the mere fact of measurement can change the measurement result. This means that the very process of measurement affects what is being measured, and this is contrary to the usual understanding of physics. Some scientists believe that this strange phenomenon may be due to the fact that the future can influence the past. According to this theory, measurement affects what will be ... >>

AmberSemi digital chip for direct AC to DC conversion 14.03.2023

New Mini Cooper EV 2024 13.03.2023

The base variant of the 2024 electric Mini Cooper with a 40kWh battery will get a 181bhp/135kW engine (the same as the current Cooper SE), while the 54kWh upgrade will get 215bhp/160kW. This is a significant upgrade since the previous Mini came with 32,6kWh. Larger batteries will provide a range of 300 km and 400 km respectively for the WLTP test cycles. There are no official EPA estimates yet, but they are usually lower, so they will be approximately 230 and 290 km, respectively. For 2025, Mini wants to offer a John Cooper Works version with even more power, up to 250 hp. The interior design will be in keeping with Mini's retro aesthetic, writes Autocar. However, even an electric Cooper will receive a physical key, and there will be no driver display behind the wheel - all information will be displayed on a screen located in the center. Mini will still produce an internal combustion engine model, but expects EVs to account for 2025% of sales by 50, up from 15% today. Formerly a manufacturer ... >>

FGF21 injection helps sober up 13.03.2023

American researchers sobered mice by injection of the hormone FGF21, which reacts to the introduction of ethanol into the body. The connection allowed the animals to regain consciousness and coordination of movements twice as fast. The FGF21 hormone is produced by the liver under the influence of a number of stress factors, such as starvation, lack of protein, or the action of ethanol. Previous studies have shown that the compound protects the liver from damage due to alcohol consumption, as well as reduces alcohol cravings and encourages drinking more fluids to prevent dehydration. Behavioral change means that the action of the hormone crosses the blood-brain barrier to the brain. Scientists at the University of Texas Southwestern Medical Center and colleagues decided to clarify the mechanism of its action. First, the scientists heavily ethanoled two groups of mice - normal and blocked by the hormone FGF21. Although within 15-20 minutes they all became intoxicated and lost the ability to navigate in space, in modified animals ... >>

Augmented Reality Contact Lenses 12.03.2023

Korean developers, in collaboration with scientists, have introduced contact lenses that can work as an augmented reality screen. Developers from the Ulsan National Institute of Science and Technology assure that the operation of such lenses does not require a large amount of energy. The gadget can fully display white, blue and green spectra. "The main disadvantages of known AR devices are the price, experimental technologies and bulky design. Our contact lenses are inclusive, comfortable and can be worn for several hours without problems," the scientists note. The lenses were based on electrochromic (color-changing) displays based on Prussian blue pigment. In the pilot version, the lenses contained limitations in the display of words or pictures, since at first it was difficult for scientists to apply microcircuits to an accessory using the galvanization (electronic current) method. In the new version, experts have replaced this technique by printing chips and displays on a 3D printer. As a result, the team received a miniature ... >>

World's most complex insect brain map ever created 12.03.2023

Researchers understand the structure of the brain and map it in sufficient detail, but they still do not know exactly how it processes data - this requires a detailed "diagram" of the brain. Now scientists have created such a map for a fruit fly larva. It is called a connectome and reflects 3016 neurons and 548 synapses of an insect, reports Neuroscience News. The map will help researchers better understand how insect and animal brains control behavior, learning, bodily functions, and more. This work may even inspire improvements in artificial intelligence networks. "Until now, we haven't seen the structure of any brain other than the C. elegans roundworm, the low chordate tadpole, and the anelid larva, which have several hundred neurons," said Professor Marta Zlatik from the MRC Molecular Biology Laboratory. worked without circuits in ours. Without knowing the structure of the brain, we can guess how calculations are made. But now we can start ... >>

Estimate of human height over 2000 years 11.03.2023

Scientists have published a study examining the growth of adult men and women in Milan over the past 2000 years. It demonstrated a stable effect of the environment on the physique. Human growth depends on the interplay between genetics and environmental factors such as fetal health, childhood nutrition, the impact of disease, and environmental epigenetic factors that may span previous generations. While genetics can influence how tall a person can become, the environment in which they were born plays a significant role in how much their genetic growth potential is realized. In past studies, people's height has been linked to environmental factors. Human stature declined sharply in the transition from hunter-gatherer to agricultural societies. If they used historical facts to make a film about the Trojan War, they would have to hire male actors up to 169 centimeters tall. Since then, human height has slowly grown, sometimes it could decrease ... >>

Vinyl record sales surpass CD sales for the first time 11.03.2023

In 2022, vinyl record sales surpassed CD sales for the first time, according to the Recording Industry Association of America (RIAA). This has happened for the first time since 1987. Last year, 41,3 million records were sold worldwide against 33,4 million CDs. In monetary terms, the gap is even larger: $1,2 billion versus $482,6 million. At the end of last year, records accounted for 71,2% of all revenue in the physical music media market. It can also be noted that the overall revenue in the music recording market continues to grow. While 2021 results were roughly in line with the market peak in 1999, 2022 revenue grew even more, reaching nearly $16 billion. Of course, the lion's share falls on the digital format. Or rather, for subscription services. ... >>

Time zone for the moon 10.03.2023

On July 21, 1969, Neil Armstrong took the first life-changing step on the moon. This happened just when the standard universal time on our planet reached 2:56 am. But what time was it for the Nile? There is no answer to this question yet, but given the plans for settling the moon, this may change. At a recent meeting in the Netherlands, representatives of space organizations from around the world agreed that we need to introduce a proper lunar time zone - an internationally recognized common lunar standard time that all future missions can easily use for communication and navigation. A recent meeting in the Netherlands was organized and hosted by ESA researchers, but the discussion was collaborative. The goal is to create a mutually agreed upon framework called LunaNet that will provide a common interface for all future monthly missions, optimizing their networking, navigation, detection, information and communication. Timing will be key for future operations. In the next few years to the moon ... >>

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 ... >>

Apple plans to turn its AirPods into hearing aids. Now Apple is working on expanding the capabilities of AirPods so that they can become a full-fledged medical device. The company plans to create a headset that will be useful for people with hearing problems. Additional features may appear in the company's new devices within a year or two. 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 ... >>

A new method for diagnosing anxiety disorders 07.03.2023

Researchers at the Indiana University School of Medicine, USA, have discovered blood biomarkers that can determine the risk of developing anxiety. Thus, according to the blood test, it will be possible to provide for mood disorders, increased anxiety and excitement. During the study, scientists used methods to identify depression, post-traumatic disorder, bipolar disorder and pain. By the same principle, they analyzed the biomarkers of anxiety. The first group consisted of 41 men and 17 women. Their level of anxiety changed at least once from one visit to the next. This group allowed the team to look for possible biomarkers that could be associated with changes in anxiety. In the second group there were 32 men and 8 women, biomarkers were checked on their blood tests, which can predict anxiety. The third group included 161 men and 36 women who suffered from severe anxiety attacks. There, researchers were convinced of the method for predicting high and wedge states. ... >>

Shoe polisher for cars 07.03.2023

Many car owners get annoyed when passengers with dirty shoes sit down to them, because the condition of the floor mats affects the overall appearance of the cabin. To solve this problem, they came up with a universal device - Tidee Ride. The simple design of the product allows you to attach it to the car door, and then take it out and clean your shoes with just one touch. The device is equipped with a magnetic clasp that keeps it closed while driving. In addition, it has a felt coating on the area in contact with the car. At the same time, it should be noted that the Tidee Ride cannot be used as a step to get into the car, but the manufacturer plans to make this possible. Along with this, the company has planned several color options that will suit the interior of a large number of cars. While the device is sold in black. ... >>

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 ... >>

Schematic diagrams for kombucha 05.03.2023

Cheap, lightweight, flexible yet durable PCBs are essential for wearable electronics. Her future may be based on flexible schedules based on bacterial cultures known as kombucha, or kombucha. SCOBY (a symbiotic culture of bacteria and yeast) creates a dense, gel-like mass that is held together by the cellulose fibers of the bacteria. In addition to being a popular drink, kombucha cultures promise to be a useful biomaterial. A team of scientists from the University of the West of England at Bristol used commercial cultures of kombucha to grow bacterial mats and then dried the resulting products, applied to plastic or paper, at room temperature outdoors. The rugs do not tear or collapse even when immersed in water for several days. One of the tested mats withstood oven temperatures up to 200°C, although the material does ignite on contact with an open flame. Researchers were able to print circuits from a conductive floor ... >>

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.

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 ... >>

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 ... >>

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. ... >>

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 ... >>

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. ... >>

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

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, ... >>

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 ... >>

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. The results showed that prodemos participating in the early retirement program ... >>

Intel set price at 699 ... >>

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 ... >>

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 ... >>

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 ... >>

The world's largest wave power plant will be built 19.12.2022

The Swedish company Eco Wave Power and the Turkish company Oren Ordu Eneas have announced the construction of the world's largest wave power plant. The design capacity of the plant will be 77 MW. The construction cost will be about $150 million. The installation for converting the energy of sea waves into electricity will consist of a fixed modular array of steel floats, hinged to levers with pistons. The latter will pump the working fluid through an underwater hose line to an onshore generator that produces sustainable energy. The construction of the project will be carried out in several stages.

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 ... >>

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

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 ... >>

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. This is how FiberX was born, a flavorless functional fiber that can be added to low fiber foods such as white bread, cakes, pasta, pizza and sauces. To get the innovative invisible fiber, project leader from the RMIT Center for Food Research and Innovation Asghar Farahnaki and his team used advanced starch modification technology with approved food materials. FiberX is considered bland and tasteless, but it is also suitable for fortifying low calorie, low glycemic foods. “Now we can add extra fiber to foods like white bread without changing the taste or texture, which is one of the biggest problems with food today. ... >>

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. ... >>

ClearSpace intends to build a spacecraft resembling a giant squid, with many tentacles that can "hug" debris. Another company, Astroscale, will use a spacecraft with a long robotic arm to grab debris. 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. ... >>

Through such a VR helmet, scientists intend to study the behavior of mice by simulating various maps with unique features and challenges. ... >>

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 ... >>

Sparrow boasts computer vision that allows it to analyze products in stock. The presence of artificial intelligence ensures the performance of various manipulations with goods. One robotic mechanism can replace several people at once. At the same time, safety precautions in places where people and robots work together are not always observed. According to experts from the Center for Investigative Journalism, in the three years preceding the coronavirus hysteria (2016-19), the injury rate at Amazon automated enterprises was 50% higher than that in workshops using exclusively human labor. 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 ... >>

Hywind Tampen, world's largest floating wind farm, launched 13.11.2022

Norwegian energy company Equinor, better known for projects in the oil and gas industry, has begun commissioning the world's largest (according to it) floating wind farm, with more turbines to start operating at the end of the current beginning of next years. The first turbine under the Hywind Tampen project started operating on Sunday.

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 ... >>

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. ... >>

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. ... >>

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 ... >>

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. ... >>

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 ... >>

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

Scientists have recorded an unprecedented burst of gamma rays (GRB), which at some wavelengths looked brighter than any similar burst of energy observed before. 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 ... >>

Created plant honey 21.10.2022

Bees did not participate in its creation and production of vegetable honey. The new product does not contain processed syrup and concentrate. Almost every day there is information about the creation of useful analogues of the most popular products. With avocado, they went even further and created an updated ecovado vegetable. But honey from the largest European producers of organic food, Narayan Foods, will be the first vegetable in the world. By creating it, the company was able to meet the constant demand for quality honey with bee-friendly processes.

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. ... >>

Crystals with DNA of the willing will be sent to the moon 19.10.2022

Space Crystals LLC plans to crystallize a client's DNA in space and deliver these stable crystals to the surface of the Earth's satellite using lunar landers. Space Crystals has booked payload space for its first such delivery on a lander in 2023, the company said. The technology, backed by commercial space company Waypoint 2 Space and founder Kevin Heath, costs customers $150 and is designed to "sustain existence in the universe." The concept involves infusing two crystal solutions with the client's DNA and then launching the solutions into space to become "two separate and unique crystals". The technology is unique and patent pending, and space crystals say that implanting crystal DNA into space has never been done before. The microgravity conditions provided by spaceflight allow crystals to grow into unique shapes. ... >>

Plana hybrid-electric air taxi 19.10.2022

Korean startup Plana Aero has begun work on a new long-haul hybrid-electric VTOL air taxi designed to carry up to seven people about 350 miles (500 km) at speeds up to 217 miles per hour (350 km/h). The eVTOL looks pretty unique in concept renders, with its long, thin fuselage turning into the top of the main wing. The propulsion system is a full thrust vectoring design using large inclined five-bladed electric propellers. Two are mounted on the canards, two on the outer leading edges of the main wing, and the third pair is located closer to the fuselage on the trailing edge of the main wing. The two rear propellers tilt down for VTOL operations, while the others tilt up. This is because they are configured as cruising pushers; if they leaned up like the others, they would have to change their rotation when going into cruising ... >>

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 ... >>

Hydrogen dump truck 16.10.2022

Three stories high, fully loaded, the classic mining truck is one of the largest vehicles on the planet. The mining industry contributes up to 7% of global carbon emissions annually. About 50% of this volume is accounted for by dump trucks for transporting heavy rocks. So Seattle-based First Mode wants to replace its powerful diesel engine with a hydrogen engine. First Mode has created the world's largest mobile hybrid hydrogen power plant, combining hydrogen fuel cells with battery power. It weighs as much as five elephants and is capable of carrying a load equal to the weight of 100 elephants. In May of this year, the hydrogen hauler made its official debut at the Mogalakwena mine in South Africa, owned by Anglo American. The multinational mining company estimates that the average mining truck in its fleet consumes 900 liters of diesel per year. Recently, a growing number of industries - from land transport to aviation - are considering hydrogen ... >>

In the 2021-22 wheat planting season, it has been successfully demonstrated on 580 acres for planting wheat in leftover honeydew in farmers' fields. Doc ... >>

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 ... >>

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. There are models for 5.0, ... >>

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 ... >>

Green energy will save the world trillions of dollars 21.09.2022

A post-carbon transition study by the Oxford Martin Program shows that a decisive transition to nearly 100% clean energy by 2050 will result in $12 trillion in energy cost savings. Other benefits of this move include providing more energy to the global economy and increasing access to energy for people around the world. The results are based solely on the cost of various energy technologies and do not take into account the costs associated with climate damage and adaptation to climate that could be avoided by switching to clean energy. The research team used major energy models to analyze thousands of transition cost scenarios and found that over 20 years, all models consistently overestimated future cleantech costs, while the real cost of solar fell twice as fast as the most ambitious projections. Then commands ... >>

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. During the excavations, the researchers found the so-called white lead. In antiquity it was one of the most important pigments. It is believed that the synthesis of such pigments contributed to the development of art and cosmetics throughout the world. In this case, an exceptional discovery is that the found white is recognized as the earliest in the history of mankind. The remains of white cosmetics were found on the walls of a set of bronze items that were excavated from an ancient tomb on the territory of the modern village of Liandai. The burial is dated to the eighth century BC. The analysis of radioactive and stable carbon isotopes helped to identify whitewash, as well as clarify their age. The results showed that synthesized lead white was already used in ancient China. ... >>

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

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 ... >>

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 ... >>

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 ... >>

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. ... >>

Floating robot to explore a volcano after an eruption 28.08.2022

The robot drone Maxlimer went to the Pacific Ocean to depict the Hunga-Tonga-Hunga-Haapai volcano on the map after a powerful eruption. The floating apparatus was developed by the British company Sea-Kit International. The data obtained speaks of the prolongation of volcanic activity in the region. The 12-meter unmanned boat is equipped with a winch that allows you to lower the mapping equipment under water to a depth of 300 meters. 10 cameras in real time transmit images to screens at the headquarters of Sea-Kit International in the British village of Tollesbury, located in Essex in the south-east of England.

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 ... >>

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. The study shows that bioglue is compatible with living tissues of rats. It can also potentially be used to deliver drugs through the skin. ... >>

Biodiversity conservation with vanilla 20.08.2022

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 ... >>

German startup Bluu Seafood has unveiled the first lab-grown seafood. Specialists managed to make fish sticks and balls, the main ingredient of which is cultured fish. It took two years of work to achieve a nice texture using the start-up's established food technology processes. "Fish balls and fish fingers are flavored just right by the cells and the unique combination of botanical ingredients that make up the product. The details are, of course, our trade secret. It's important that we don't add artificial flavors," says Sebastian Reikers, co-founder of Bluu Seafood. By the end of 2023, the company plans to launch laboratory-grown seafood in the Singapore market. Bluu Seafood plans to gain approval and introduce its products to the US, UK and EU. ... >>

Polymer additive to increase oil recovery 18.08.2022

Scientists in Kazakhstan have developed a polymer additive. It will help improve the efficiency of aqueous solutions used in oil production. The synthesized terpolymer has an "anti-electrolyte" effect, increases the viscosity of salt water and does not lose its properties even at high temperatures. "A feature of our thermopolymer is its heat resistance, which allows to preserve the astringent properties of the solutions used in polymer flooding and affect the increase in oil recovery," the author of the project, Iskander Gusenov, explained to Kazinform. The Kazakh state oil company Kazmunaigas is in preliminary talks with the trading division of the Azerbaijani state company SOCAR on permission to sell 1,5 million tons of Kazakh oil per year through the Azerbaijani pipeline, through which oil will be delivered to the Turkish Mediterranean port of Ceyhan. ... >>

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. To do this, you need to use concentrated light. Take, for example, a magnifying glass. In this case, the waiting time can be reduced to 30 seconds. The team of creators noted that the tool has a transparent texture, so there is no need to match it to the color of the car. The novelty will go into production in the near future. ... >>

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 ... >>

Most importantly, this solution eliminates the need to use multiple monitors for this. To avoid accidental clicks, Lumina decided not to make the screen touch. Instead of touches and gestures, all manipulations are performed from the application. You can also not ... >>

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 ... >>

Body Ultrasound Stickers 11.08.2022

MIT engineers have developed a tiny sticker that can continuously take ultrasound images of internal organs for 48 hours. This technology will help create stickers and stickers that can wirelessly track any objects in the body. Typically, ultrasound procedures use a thick, cold gel applied to the skin before inserting the probe. This gel is necessary for a clear transmission of ultrasonic waves from the probe to the internal organs and back. The authors of the new work came up with innovations, they placed the hydrogel in a thin elastomeric membrane. The result is an ideal elastic material that adheres to the skin and effectively transmits ultrasonic waves. The elastomer prevents dehydration of the hydrogel, the authors explain. The other part of the device contains an array of hundreds of tiny ultrasonic transducers. Study co-author Chonghye Wang explained that this combination of a dense array of sensors with an elastic ... >>

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 ... >>

A paper battery is activated by a couple of drops of water. 06.08.2022

A team of Swiss scientists has developed an environmentally friendly and fully biodegradable low-power battery for wearable electronics and sensors. The battery starts working after applying a couple of drops of water to its surface. A prototype of a pair of such elements powered an electronic clock for more than an hour. It is expected that such elements will minimize the environmental damage caused by the growing flow of smart electronics. The prototype of the battery is a strip of plain paper coated with common table salt on its surface. A layer of graphite flakes is added to one side of the paper - this is done using a specially made paint. Thus, the battery receives a cathode. An anode in the form of a layer of a mixture of graphite and zinc is applied to the reverse side of the paper. To start the redox reactions in the battery, which will lead to the generation of electric current, it is enough to put a couple of drops of ordinary water on it. Water dissolves salt and creates an ionic space in the paper layer of the battery. ... >>

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. ... >>

Transistors that work 10 times faster than brain synapses 03.08.2022

Researchers at the Massachusetts Institute of Technology have developed programmable transistors that operate 10 times faster than brain synapses. The technology used for analog machine learning provides not only high data processing speed, but also good energy efficiency. The working mechanism of the device is to electrochemically insert a tiny ion, a proton, into an insulating oxide to modulate its electronic conductivity. Scientists used a powerful electric field to accelerate protons and put ion transistors into nanosecond mode of operation. The researchers note that the secret of new devices in the use of inorganic phosphorus silicate glass. It provides ultra-fast movement of protons, since it contains many nanometer-sized pores, the surfaces of which provide diffusion paths for elementary particles. It can withstand very strong pulsed electric fields. Action potential in biological ... >>

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 - ... >>

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 ... >>

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 ... >>

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 ... >>

Strength Shirt 13.07.2022

Engineers at ETH Zurich's Sensory Motor Systems Laboratory have been able to create artificial muscles from tissue. 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).
