New ways of liver regeneration have been found 22.10.2023

Researchers in the United Arab Emirates have discovered innovative ways to restore the liver. Foreign sources report on epigenetics methods that can promote the regeneration of this important organ of the human body. World scientists have long been looking for unknown ways to renew the cells of human internal organs. An important discovery in this area was made by a team of specialists from the UAE. According to the researchers, an effective way to stimulate liver regeneration is to remove certain parts of the epigenome responsible for suppressing jumping genes. This method results in a redistribution of epigenetic marks. This is explained by the fact that a form of epigenetic compensation prevents the activation of transposable elements of the genome. It blocks the regulation of gene expression by compensatory epigenetic marks. This process ensures that repressive genes are activated earlier, which provides support during regeneration after surgical removal. ... >>

Liquid writing technology 22.10.2023

German scientists from the Technical University of Darmstadt and John Gutenberg University have presented innovative technology that allows the creation of durable images in a liquid medium.

Climate change has affected the taste of beer 19.10.2023

Global climate change is affecting beer production by changing the characteristics of hops and therefore affecting the taste of the drink. Scientists from the Institute for Global Change Studies of the Czech Academy of Sciences have found that due to rising temperatures and the fate of dryness in hops, the content of alpha acids, responsible for the characteristic taste and bitterness of beer, is decreasing. The study found that global warming is causing hops to ripen earlier, up to 20 days earlier than usual. This process partially occurs during periods of high temperatures, which makes it difficult for alpha acids to form. Decreased rainfall and the incidence of droughts are reducing hop yields, with yields expected to decline by 2050% and alpha acid content by 18-20% by 30. Scientists offer several solutions for beer producers. One of them is to transplant hops to higher areas where it is less hot, or to places with the above groundwater levels. Another option is to introduce irrigation systems and switch ... >>

To avoid mating, female frogs play dead 16.10.2023

Scientists have discovered that female European common frogs have developed several methods to avoid unwanted mating, including the surprising strategy of faking their own death. Female European common frogs (Rana temporaria) exhibit a mimicry strategy by appearing dead when multiple males attempt to mate at the same time. This behavior has been observed and recorded in laboratory conditions. Frogs of this species are known for their active reproduction, gathering in large groups near bodies of water. Typically, the number of males exceeds the number of females, and as a result, several males compete for the right to mate with one female. Sometimes such attempts can lead to the death of the female. However, females have evolved a variety of strategies to prevent unwanted matings. These strategies are activated when the number of males is too large, when a female is not interested in mating with a particular male, or when she ... >>

Bilingualism improves brain health and mental health 12.10.2023

Scientists from the Jülich Research Center in Germany shared new discoveries about the benefits of bilingualism for the brain. There are many compelling arguments that being bilingual can help you maintain mental health throughout your life. Modern research supports this hypothesis, indicating that bilingualism at an early age significantly improves brain function, which continues into old age. In a study of 224 monolingual and 175 bilingual volunteers, researchers used magnetic resonance imaging (MRI) to measure the volume of gray matter in the posterior inferior left frontal lobe and the inferior left parietal lobe. These brain regions are responsible for language comprehension and production, and their functional and anatomical connections are closely interconnected. "Over time, as the new language becomes more stable, the excess gray matter is converted into tighter connections and better connections in the white matter. This can ... >>

Tired of your own thoughts 11.10.2023

It is known that mental work can cause fatigue no less than physical work. Scientists from the Pitié-Salpêtrière University Hospital in Paris conducted research and, according to them, identified the chemical causes of fatigue associated with mental processes. Experts have suggested that cognitive work leads to chemical changes in the brain. Scientists believe that mental fatigue is caused by the accumulation of a certain chemical in the brain responsible for regulation. This substance, known as glutamate, is present in the central nervous system of mammals and plays a key role in a variety of processes such as learning, memory and the sleep cycle. To test their hypothesis, the researchers conducted an experiment. Participants were asked to perform various mental tasks for 6 hours. Half were given simple tasks, and the other half were given more complex ones. Scientists found signs of fatigue only in the group that did more complex tasks. For measuring ... >>

Quantum engine running without heat 11.10.2023

A team of researchers from the Department of Quantum Systems at the Okinawa Institute of Science and Technology (OIST), collaborating with scientists from the University of Kaiserslautern-Landau and the University of Stuttgart, have presented a working quantum engine that operates without the use of heat, unlike traditional mechanisms based on thermodynamic principles. A quantum engine differs from conventional ones, since its operation is not associated with an explosion of the fuel mixture and air. Instead, scientists change the quantum characteristics of particles in the gas, bypassing the use of heat. At extremely low temperatures, when quantum effects occur, bosons have a lower energy level compared to fermions. This energy gap can be used to power a motor that converts bosons into fermions and vice versa. Professor Thomas Busch, head of the quantum systems department, explained: "To turn fermions into bosons, we can combine two fermions in a mole ... >>

This discovery not only provides valuable information about the chemical composition of the oceans, but also highlights the importance of scientific research made possible by the JWST telescope. "Scientific understanding of chemical diversity is especially important given that we live in a world where carbon is the basis of life. Our work will help determine whether Europa's ocean is capable of supporting life as we know it, or whether it creates favorable conditions for the existence of other forms of life." - notes Geronimo Villanueva, principal investigator at NASA's Space Flight Center. "This suggests that we can learn some basic things about the composition of the ocean before we drill into the ice to get the full picture." Of particular importance is the presentation ... >>

Rapid recovery of valuable metals from old batteries 10.10.2023

Rice University scientists have unveiled an innovative way to recycle obsolete lithium-ion batteries that significantly reduces the amount of byproducts and the time required for recycling. The resulting metals can be reused in the production of new batteries. This technique is based on instant Joule heating technology used to process crushed cathode-anode mass. The materials are heated to a temperature of 2100 K in a matter of seconds, eliminating inert layers from their surface. A weak solution of hydrochloric acid is then used to leach the metals. Compared to traditional methods, the new technology is able to dissolve the same amounts of substance in less than 20 minutes, instead of the usual 24 hours. It is noteworthy that weak acids act as solvents, which reduces energy consumption, the need for water and acid, and, consequently, the cost of processing. With the increase in the number of electric vehicles and the breakdown of ... >>

Don't hesitate to become a father 09.10.2023

Parenthood is an important milestone that requires preparedness and determination. Many people put off this important transition in their lives, seeking first to build a career and ensure financial stability. However, scientists emphasize that delaying the decision to become a father can lead to serious problems in the future.

These sensors allow the robot to adjust the pressure applied and receive feedback, identifying lumps that may indicate the presence of a disease. After training on a silicone breast model, IRIS successfully completed the palpation task. Using machine learning techniques, scientists believe that IRIS can help provide quick and effective initial screenings, helping to prevent disease. The new method involves using an ionic liquid as a metering or throttling system in engines. Energy supply via ... >>

The Nobel Prize is harmful to its laureates 08.10.2023

For more than a century, the Nobel Prize has been the top priority for scientific awards, but new research published by the National Bureau of Economic Research (NBER) in the US suggests it may be more toxic than beneficial for its recipients. The engineers, led by David Studderd, analyzed data on Nobel Prize winners in medicine and physiology from 1950 to 2010. The researchers used statistics on the number of publications, citations, and novelty of research. The results revealed that, before receiving the award, future Nobel laureates are more likely to publish than those who go on to win the Lasker Prize, another distinguished scientific award. However, after the Nobel Prize is awarded, there is a decrease in the scientific activity of the laureates, and their performance becomes comparable to the winners of the Lasker Prize, and sometimes even inferior to them. Scientists note that this is not due to a drop in motivation among the Nobelists, but probably reflects profound changes in their lives ... >>

Safe fuel will not ignite when in contact with fire 08.10.2023

Scientists from the University of California have introduced a revolutionary fuel that does not ignite when in contact with an open flame. During the combustion of this fuel, only the evaporating molecules that react with oxygen are ignited. The new development is designed to make the fuel safer, especially in emergency situations, by reducing the likelihood of accidental fire during storage or transportation. Chemical engineers used ionic liquid as the basis for the new fuel, which is a liquefied form of salt. This liquid has a lower melting point and low vapor pressure compared to regular table salt. Experts also made changes to the chemical formula, replacing chlorine with perchlorate. Experiments showed that when trying to ignite the ionic liquid with ordinary fire from a lighter, no combustion occurred. However, when voltage was applied in combination with the fire of a lighter, the fuel ignited. It is interesting that when the current is turned off ... >>

Laser control using sound 07.10.2023

Engineers achieved redirection of laser beams without using traditional optical elements such as lenses and mirrors, and instead used an acoustic grating.

Optimal combination of crops and solar panels 04.10.2023

Researchers from Wageningen University in the Netherlands have concluded that placing farmland and solar panels on the same site is a viable approach. According to experts, the combination of crops and solar panels on an area of ​​1,25 hectares can lead to yields and electricity production equal to the results of two separate fields of 1 hectare each. Large-scale cultivation of plants and electricity production in the same area appears to be quite feasible, despite some reduction in crop yields and electricity production per hectare compared to a situation where the land is used for only one function. However, the overall productivity per hectare using agrophotovoltaics is superior to that of growing crops and producing electricity in two separate fields. Research carried out in Germany on several crops confirmed that the achievement of production ... >>

Mechanical guards to protect against attacks by wild animals 04.10.2023

Japan has introduced unusual measures to ensure the safety of elderly citizens from bear attacks - mechanical wolves, known as Monster Wolf, have come into action. Originally created to terrify wild animals on farmland, these terrifying robotic wolves are now being used to prevent bears from attacking people.

Embryo from stem cells 10.09.2023

Scientists from the University of Cambridge and the California Institute of Technology have made significant progress in growing artificial "near-embryos" from stem cells. The experiment provides new opportunities for research into genetic disorders, but also raises serious questions about morality and legality by creating structures that closely resemble the human embryo. The embryo created had absolutely no relation to eggs or sperm and was devoid of a heart or brain development. However, it contained cells that form the placenta, the yolk sac, and the embryo itself. This progress has been achieved by reprogramming embryonic stem cells. Despite this, the use of synthetic embryos for clinical purposes is not possible in the near future. This would be a flagrant violation of the law and it remains unclear whether such structures can develop further after the early stages of formation. Researchers hope these models will have an impact ... >>

New form of oxygen discovered 09.09.2023

Scientists at the Tokyo Institute of Technology have discovered two new oxygen isotopes that cast doubt on our understanding of the structure and stability of the atomic nucleus. These isotopes, oxygen-27 and oxygen-28, have the largest number of neutrons of any known oxygen isotope. Oxygen-28, which contains 20 neutrons in its nucleus, was expected to be stable, but turned out to be unexpectedly unstable. This discovery raises questions about the accepted ideas about the "magic" numbers of protons and neutrons in atomic nuclei, which were thought to provide stability. The study was conducted at the RIKEN Radioactive Isotope Beam Factory, where scientists used a cyclotron-type accelerator to create unstable isotopes. As a result of the experiment, both new oxygen isotopes turned out to be unstable and decayed into oxygen-24 and a few free neutrons after only a short period of time. It is especially interesting that oxygen-28, with 20 neutrons, diverged from the theoretical ... >>

Dual use battery 06.09.2023

Scientists have developed a unique hybrid battery system that can not only store and provide electricity, but also generate useful chemical compounds in the process. Conventional batteries store energy in their electrodes and transfer it to the electrical grid when they are discharged. Another type of battery, redox batteries, store energy in chemicals that transition between two states while remaining inside the battery. The hybrid system combines both of these concepts to simultaneously store energy and create additional chemicals. The key point in the development of this technology is the use of a bifunctional metal catalyst for the anode, made from a monoatomic alloy of rhodium and copper. This catalyst makes it possible to convert the furfural contained in the electrolyte into furfuryl alcohol when the battery is charged, and when the battery is discharged, furic acid is formed. For the cathode, the researchers used material ... >>

Creating the Perfect Chocolate Texture 05.09.2023

Chocolate is famous not only for its sweet taste, but also for its amazing soft texture. Scientists at the University of Guelph in Canada have found an innovative way to create the "perfect chocolate" without the need for an expensive and complicated tempering process. Tempering is required to create high-quality chocolate that has a glossy surface and a characteristic sound when broken. This process involves repeatedly slowly heating and cooling the melted chocolate so that the fats in the cocoa butter are converted into a specific crystalline form known as "Form 5". "Probably, each of us has come across bad chocolate, which either crumbles or is too soft," the authors of the study note. This is because it is difficult to maintain a perfect tempering process in mass production. So scientists have developed a way to create the "perfect chocolate texture" quickly and easily.

Drinking hot drinks when it's hot 01.09.2023

In conditions of ultra high temperatures, many prefer to relieve discomfort with cool drinks. But it turns out that hot drinks can also play an important role in cooling the body, as they help reduce body temperature more effectively. This discovery was made by Peter McNaughton, a researcher at King's College London. “At first glance, it may seem that hot drinks will only increase the feeling of heat. But it is worth remembering that the human body has an amazing ability to maintain a stable body temperature,” the expert sheds light on this aspect. Experiments have shown that hot drinks activate specific receptors in the nervous system called TRPV1. These receptors send signals to the body to cool down. In response to this, the body begins to sweat more actively. A particularly effective method to cope with the heat is the release of sweat. In the presence of wind or a fan, sweat evaporates faster, which contributes to more ... >>

The magnetic moment of the muon is the fifth force of nature 24.08.2023

Scientists from Fermilab have made a sensational discovery, declaring significant deviations in the anomaly of the magnetic moment of the muon - a complex and unstable elementary particle. These observations go beyond the standard physical model, leaving science with the puzzle of the unknown effect on the muon's magnetic moment. The muon, although it is an unstable particle, has a significant mass - 207 times heavier than an electron. Because of this mass, measurements of its magnetic moment turned out to be much more accurate and accessible for research. In contrast to the anomaly of the magnetic moment of the electron, which scientists have successfully explained through interaction with the quanta of the electromagnetic field, the anomaly of the magnetic moment of the muon poses a mystery to science. The existing model of elementary particles and fields does not provide an explanation for such significant deviations in the magnetic moment of the muon.

Sound can travel even in a vacuum 14.08.2023

Finnish physicists have discovered that, under certain conditions, sound is able to travel through a perfect vacuum, contrary to the traditional understanding that sound requires a medium to propagate. Sound propagation usually requires a material medium through which vibrations can be transmitted. On Earth, it could be air or water. Sound arises from vibrations that set atoms and molecules in motion within a medium. These vibrations are transmitted from one particle to another and are interpreted by the human ear as sound. An ideal vacuum implies the absence of any material environment. In theory, under such conditions, sound should not propagate. However, scientists from Finland have discovered that the so-called "vacuum" can still contain electric fields that can cause vibrations in piezoelectric crystals. This may be a key factor in the study of sound transmission in empty space. Piezoelectric materials are capable of converting mechanical energy into ... >>

The recommended number of steps per day has been determined 08.08.2023

Studies conducted by scientists show that over the past hundred years, humanity has significantly reduced the number of daily steps - by 96%. It is necessary to realize that the complete cessation of motor activity can lead to the threat of extinction of the human species. But there was an alternative, and this is not the famous ten thousand steps. It turns out that this number became the standard by mistake when, in 1964, a Japanese company launched a crocometer on the market, which translates as "10 step counter." This novelty impressed customers so much that they quickly accepted this value and began to strive for it without much motive. In fact, the optimal number of steps per day for each person depends on many factors, including overall health, level of physical activity during the day, and even eating style. Harvard University professor Yiming Lee conducted a study on this topic together with colleagues. About 000 American women over 16 took part in ... >>

Discovery of waves in Jupiter's magnetosphere 25.07.2023

During nearly half of Jupiter's magnetosphere boundary crossings, the Juno space station encounters waves that cause the planet's magnetic field to interact with the solar wind, according to a new study. This phenomenon was previously detected on Earth and Saturn, but was first recorded on Jupiter. Jupiter has the strongest magnetic field of all the planets in the solar system, surpassing the Sun by almost 15 times. Its magnetic field accelerates charged particles that enter the magnetosphere from the solar wind or are ejected by the moon Io. This is manifested in the bright auroras and unique dawn storms that the Juno space station has been studying for more than seven years. With the help of this station, astronomers from the University of Texas at San Antonio, together with colleagues, discovered a hitherto unknown phenomenon on Jupiter - Kelvin-Helmholtz instabilities. Kelvin-Helmholtz instabilities arise at the boundary of two media with different velocities and directions, ... >>

Coolest star emitting radio waves found 25.07.2023

Astronomers from the University of Sydney have made an exciting discovery by detecting radio emission from an ultracold brown dwarf. This dwarf is a ball of gas that "boils" at a temperature of about 425 ° C without nuclear reactions. Usually such stars do not emit radio waves, so the reason for this phenomenon remains a mystery. The star T8 Dwarf WISE J062309.94-045624.6 lies about 37 light-years from Earth. Its radius is from 0,65 to 0,95 of the radius of Jupiter, and the mass is 4-44 times the mass of the largest planet in the solar system (the exact value of the mass has not yet been determined). Even though this brown dwarf is not the coldest, astronomers have only observed radio emission from hotter stars so far. Size comparison of various objects: Sun, low-mass star, brown dwarf, Jupiter, Earth. Brown dwarfs are intermediate between the smallest stars where nuclear reactions take place. ... >>

Green Revolution in the Oceans: Phytoplankton Rise 24.07.2023

Over the past two decades, scientists from the US and the UK, analyzing satellite images, have found that the world's oceans are increasingly colored in green hues. The reason for this phenomenon was the rapid increase in the phytoplankton population. These microscopic organisms, including algae, use the green pigment chlorophyll to carry out photosynthesis. Because of this, the more phytoplankton, the greener their natural habitat becomes. This rapid increase in phytoplankton abundance has already had serious short-term consequences. They lead to oxygen deficiency in the environment, causing the formation of hypoxic dead zones where animals cannot survive. However, the long-term effects of algae growth on the ocean ecosystem remain to be explored. Since phytoplankton absorb carbon, its presence can be beneficial. However, further research is required to exploit this potential. ... >>

Effect of stress on brain structure 24.07.2023

Recent research by cell biology and anatomy professor Xi-Kwong Jun Liu of Louisiana State University New Orleans reveals the impact of stress on brain structure. These results highlight potential therapeutic targets in the prevention and treatment of related pathologies. In a mouse study, Liu and her team found that a single stressful event causes rapid and lasting changes in astrocytes, the brain cells responsible for clearing waste products from the brain. Stressors lead to detachment of the ends of astrocytes from synapses, which serve to transfer information between neurons. In addition, the researchers have identified the mechanism that underlies these changes. They found that during a stressful event, the hormone norepinephrine suppresses the molecular pathway responsible for the production of the GluA1 protein, which is essential for communication between nerve cells and astrocytes. These new discoveries provide a better understanding of molecular changes ... >>

Plants sense and react to root temperature 23.07.2023

Scientists at the University of Halle-Wittenberg in Germany have found that plant roots have the ability to perceive and respond to soil temperatures independently of the rest of the plant. This discovery highlights that roots not only transmit signals up the stem, but can themselves respond to changes in the environment. Previously, it was believed that the roots of plants are not able to respond to the environment on their own and exclusively obey the signals coming from the stem. However, new experiments with plants such as the common caterpillar, tomatoes and cabbage, carried out at a controlled temperature increase from 20 to 28 degrees Celsius, disproved these ideas. As the soil temperature rises, the cells at the ends of the roots begin to divide more actively, which leads to the elongation of the roots. Cutting the stems has no effect on this process. Additionally, scientists have conducted experiments with genetically modified plants that have been damaged ... >>

Fish in outer space 23.07.2023

China is preparing to send zebrafish to the Tiangong space station to study their interactions and effects on other organisms in a limited, closed ecosystem. The main focus of the study will be on studying the possible loss of bone density in astronauts during prolonged stay in a microgravity environment. The new study aims to study the loss of bone density that astronauts can experience during prolonged exposure to zero gravity. This issue could have a significant impact on future space missions. This is not the first time fish have been sent into space. In 1973, a group of fundulus fish were sent into Earth orbit to the first Skylab science laboratory to study their response to weightless conditions. The fish managed to successfully incubate dozens of eggs, from which newborn fish fundulus emerged, able to adapt to weightlessness. Also, the Japanese space agency conducted a study of the impact ... >>

Obesity Protection: Genetic Mutations as an Influencing Factor 22.07.2023

Scientists from the University of Cambridge conducted a study to understand the reasons why some people stay slim throughout their lives. They studied the DNA of nearly 2 lean, healthy people without eating disorders and concluded that genetic mutations are at the root of this phenomenon. By comparing the data with the genomes of nearly 14 people of varying weights available at the Serger Institute, the scientists found new genetic mutations associated with obesity or staying fit. “Our study shows for the first time that healthy, lean people stay that way primarily because they have fewer genes that contribute to weight gain. This means that the influence of the genetic code on our weight is much greater than we thought. Science shows that the problem of obesity is much more complicated and you can’t blame people thoughtlessly,” explains Dr. Sadaf Farooqi. At present, scientists have not yet been able to fully understand ... >>

One of the participants in the study regularly visits the gym 6 times a week, doing weight training. He usually visits the gym from 10 pm to midnight. Some of his friends think this is crazy since they are sleeping at this time. However, nighttime workouts are perfect for the busy father of two. And now these workouts have been scientifically proven to bring additional health benefits. Scientists observed blood glucose levels in overweight men who were on a high-fat diet. Participants completed high-intensity interval training for 5 days. Some trained at 6:30 am and others at 6:30 pm ... >>

Flame retardant bioplastic from unicellular algae 21.07.2023

Scientists from the US have presented a new type of bioplastic, which is derived from blue-green cells of cyanobacteria, better known as spirulina. Spirulina, which is a type of blue-green algae, is rich in vitamins and minerals. It is commonly used as a health supplement. Now researchers have applied spirulina to create a new kind of bioplastic that can decompose in a compost pit in the same amount of time as a banana peel. Bioplastic is entirely made from powdered biomass of cyanobacteria. Using heat and pressure, similar to the process of creating conventional plastics, specialists formed various shapes from spirulina powder. The choice of spirulina is due to its ability to be cultivated on a large scale, as well as the fact that cyanobacteria cells absorb carbon dioxide during growth. This makes spirulina carbon-neutral and potentially carbon-rich. In addition, it has fire retardant properties. "One of the main advantages ... >>

The brain hears silence 20.07.2023

Scientists from Johns Hopkins University (USA) conducted a series of experiments, as a result of which it was proved that the human brain actually perceives silence. The authors of the study conducted seven experiments involving thousands of volunteers. Participants were asked to listen to single and repeated pauses in the background of noise, such as the noise of a train, a busy restaurant, a market, or a playground. The researchers used the well-known "one, therefore more" illusion, which causes the listener to perceive two separate sounds to be shorter than one, even though their total time is the same. It has been found that repeated pauses are perceived by the brain as being shorter than a single pause. In other words, the brain processes silence the same way it processes sounds. Therefore, people may experience discomfort during pauses in a conversation, the authors of the study note. "We have found that the effects and illusions that we consider to be characteristic of sound processing also appear in relation to silence. This is ... >>

Laser cutting of water using hydrophobic particles 17.07.2023

Chinese scientists in the field of materials science have discovered an amazing ability to cut ordinary water using a laser. The study showed that a mixture of water with hydrophobic particles of silicon dioxide (silica) allows you to create a variety of patterns on the surface of the water under the influence of laser radiation, which may be important for the development of microfluidic chips. Laser material processing is widely used in various industries due to its high accuracy and speed. However, the use of a laser to cut water was difficult due to surface tension, which prevents the necessary pressure for cutting. The water is too fluid, making it difficult to cut. However, the possibility of laser water cutting can be of great importance for the development of microfluidic chips used in biomedicine, biology, analytical chemistry and pharmaceuticals. Scientists from Xian Jiaotong University, along with colleagues, have found a solution to this problem. They found out that before ... >>

Creative people enjoy wasting time. 16.07.2023

A new study from the University of Arizona, USA, confirms that creative people often find pleasure in spending their free time reflecting and exploring their thoughts. The study found that creative participants were less likely to experience boredom, even when alone in a room. This discovery is especially relevant during the COVID-19 pandemic, when many people have been dealing with unstructured time and feelings of isolation. However, earlier studies in psychology and neuroscience often restricted participants to certain kinds of thinking or required them to talk about thoughts they had already thought about. Little is known about how thoughts naturally arise and develop in different contexts. History shows that many famous scientists, artists and philosophers enjoyed the time spent alone with their thoughts and during such moments came to the most important ideas. In our modern times, when we are increasingly busy ... >>

Cow toilet 15.07.2023

Scientists from Germany decided to teach cows to use a special toilet. They believe this could help farmers reduce water pollution and reduce greenhouse gas emissions. Cow dung can be a problem, especially if they are in stalls where urine and feces are mixed. Because it produces ammonia, an indirect greenhouse gas. The experiment was carried out on a farm run by the Research Institute for Farm Animal Biology in Dammerstorf. Researchers Lindsey Matthews and Douglas Elliff of the University of Auckland said that the training was carried out according to the principle of "carrot and stick". To do this, they set up a special area called MooLoos, lined with artificial grass, where cows can safely urinate without endangering the environment. At the first stage, the calves were driven into the MooLoos in turn and rewarded with food if they did their "easy job" there. The next step was to increase the distance to the toilet. If there were "accidents" in d ... >>

3D printing of metal objects at room temperature 14.07.2023

Scientists from the University of North Carolina have developed a unique compound that allows metal products to be printed using a 3D printer at normal room temperature. This significant breakthrough opens up new possibilities for creating metal objects, including those that are sensitive to high temperatures, such as in the field of electronics. The basis of the new material is an aqueous suspension of copper microparticles. Microparticles of the eutectic alloy of gallium with indium (EGaIn) and hydrochloric acid are added to it. The latter changes the pH of the water to a value of 1,0, which removes oxides from EGaIn and temporarily turns it into a liquid metal state. EGaIn globules attach to larger copper particles, forming strong bonds between them. To increase the volume of the mixture, methylcellulose is added to it. The resulting viscous gel can be extruded from the nozzle of a conventional 3D printer at room temperature, allowing objects to be created by layering in succession. After printing ... >>

Heat source discovered on the moon 13.07.2023

Under the ancient lunar volcano Compton-Belkovich, scientists have discovered a huge granite formation that indicates volcanic activity that illuminated the far side of the moon in the past. Granite was discovered under a volcanic structure on the Moon known as Compton-Belkovich. This formation most likely resulted from the cooling of magma that fueled volcanic eruptions on the Moon about 3,5 billion years ago. The presence of remnants of volcanic activity in this region of the Moon is not a surprise, since researchers have long assumed that this is an ancient complex of volcanoes. However, scientists were surprised by the sheer size of this cooled magma, which extends for about 50 kilometers. The discovery of this vast granite body beneath the Compton-Belkovich volcanic complex could help scientists elucidate how the lunar crust formed in the moon's early history. "The large granite formations that we find on Earth fed large volcanoes, just as today pain ... >>

Thin plasma emitters: a revolution in noise reduction 13.07.2023

The Federal Polytechnic School of Lausanne (EPFL) in Switzerland has granted Sonexos a license to commercialize its active noise reduction technology using thin plasma emitters, which researchers have been working on for several years. The EPFL research team has developed an ultra-thin active noise cancellation system using plasma emitters that ionize the air. Layers 17 mm thick are able to block noise at a frequency of 20 Hz as effectively as a 4-meter wall. Active noise cancellation (ANC) is based on measuring sound waves with a microphone and creating anti-waves that counteract the sound. ANC works well in headphones and cars where the acoustic environment is relatively controllable. ANC can also be applied indoors, but it requires a large number of speakers or a massive wall to suppress low-frequency, long-wave noise. What if the radiators were ultra-thin sheets and not massive diffusers? coman ... >>

Ecological medicines from waste paper industry 12.07.2023

Scientists from the University of Bath (Great Britain) have developed a method for the production of ibuprofen, paracetamol and other drugs, as well as household chemicals from turpentine, a waste paper industry. Typically, oil is used to manufacture medicines, the price and availability of which depend on political events and are not constant. In addition, such production has a significant impact on the environment: according to 2019 data, the pharmaceutical industry polluted the environment 13% more than the automotive industry. New technology brings us closer to solving both problems. Scientists describe the process of converting beta-pinene contained in turpentine into pharmaceutical precursors, which are then used to synthesize paracetamol and ibuprofen. Turpentine is a by-product of paper production that is generated in large volumes. In addition, scientists have successfully used turpentine to synthesize 4-HAP, a precursor to beta-blockers, salbutamol for asthma inhalers and some household products. ... >>

Babies notice things that elude adults. 11.07.2023

We can usually recognize an object even if it flashes before us for a short time. However, if another object appears immediately after the first one, the perception of the first object suffers and we stop noticing its presence. This phenomenon of visual perception is called "reverse masking". In science, it is used to study how the brain processes visual signals. Interestingly, this phenomenon occurs even in cases where the second object does not spatially overlap the first one, but is represented, for example, by a contour or by four points surrounding the object. It is assumed that the occurrence of this phenomenon is associated with a violation of the "feedback mechanisms". The visual information we see is processed sequentially in the brain from lower to upper visual areas. However, feedback also plays an important role in visual perception, when visual signals are transmitted from the upper regions of the brain to the lower ones. It is believed that reverse masking ... >>

Ancient people could see dinosaurs 08.07.2023

Scientists have long debated whether key features of placental mammals, which include humans, appeared in our ancestors before or after the extinction of the dinosaurs. However, thanks to the research of a team of scientists from the University of Bristol (UK) and the University of Friborg (Switzerland), these disputes can be stopped. In a study of placental mammal fossils prior to the Cretaceous-Paleogene mass extinction (K-Pg) event 66 million years ago, scientists found no conclusive evidence. However, analysis of the molecular clock revealed that our ancestors existed long before this event and possibly coexisted with dinosaurs. Using a new statistical approach, the researchers were able to determine that early forms of placental mammals probably appeared in the Cretaceous and interacted with dinosaurs over time. Scientists have studied thousands of fossils of placental mammals and found the law ... >>

Methyl found in space 07.07.2023

Although the existence of active methyl cations in protoplanetary disks was suggested 40 years ago, it is only now that this important compound has been discovered and confirmed. In 1977, a hypothesis was formulated that the monovalent methane radical, namely the methyl cation (CH3+), plays a decisive role in initiating chemical processes in the interstellar medium. However, detecting this molecular formation outside our solar system has proved extremely difficult. Perhaps this is due to the high activity of methyl: its average lifetime in the free form is usually less than a thousandth of a second. As a result, it is unlikely to find a large number of such cations in one place and at one time, so that they can be detected using terrestrial telescopes. However, thanks to an international team of astronomers, it was possible to detect traces of methyl in the protoplanetary disk d203-506, located in the Orion Nebula, using space data. ... >>

Gas stove is more harmful than passive smoking 03.07.2023

Gas stoves in kitchens are fast and convenient, but not always safe, and not only because of possible household gas explosions. Using a gas stove leads to high concentrations of benzene in the air, an aromatic organic compound known to be a carcinogen, according to a new study published in Environmental Science & Technology. The gas pipeline and gas cylinders used to supply gas contain simple hydrocarbons. Usually it is methane and propane, as well as some other additives. This gas burns with the release of heat, but when completely burned, not only harmless water and carbon dioxide are formed, but also dangerous substances. The researchers in their work drew attention to benzene, one of the compounds formed during the combustion of gas. Benzene is the simplest aromatic compound, which in its pure form causes irritation of the skin and mucous membranes, can accumulate in the body and pollute the environment. Particularly alarming are its carcinogenic properties. ... >>

Rarest eye color revealed 02.07.2023

Approximately 10 thousand years ago, all people on Earth had the same shade of eyes - brown. However, due to genetic changes, a modern person has several options for eye color: brown, blue and green. And green is the rarest. According to the American Academy of Ophthalmology (AAO), only 2% of the population has green eyes, making it the rarest. 79% of people on the planet have brown eyes, while the rest have blue eyes. Ophthalmologists explain that eye color is determined by the presence of melanin, which also colors hair and skin. "People with brown eyes have a significant amount of melanin in the iris, while people with blue eyes have much less," says ophthalmologist and MD Yuna Rapoport. Due to varying amounts of melanin, eye color can range from light blue to dark brown, while green is in the middle. ... >>

Women are more sensitive to stress than men 01.07.2023

Women are more sensitive to stress than men, scientists at the Karolinska Institute in Sweden have found. They identified a group of neurons responsible for generating negative emotions and found that these neurons contain estrogen receptors, which explains women's increased sensitivity to stress. Using state-of-the-art brain analysis techniques, the researchers determined how these neurons fire during chronic stress. Experiments performed on laboratory mice have shown that these neurons connect the hypothalamus to the lateral habenula, which is responsible for reactions to reward and aversion. "Knowing which neurons in this brain pathway control negative emotions will help us better understand the mechanisms behind the development of affective disorders, including depression. This will pave the way for the development of effective drugs to treat them," said Professor Konstantinos Meletis, one of the study participants. Scientists noted that neurons associated with negative emotions and chronic stress, about ... >>

Curly hair is a natural defense against the summer heat. 29.06.2023

Scientists from the University of Southern California (USA) found that people with curly hair tolerate heat better. The researchers conducted a series of laboratory experiments on a human head model. While maintaining a temperature of 35 °C, corresponding to the warmth of the scalp, they irradiated the model with a heat lamp. The model had different types of hair: straight, slightly curly, very curly, as well as a model with a completely bald head. The skin was either dry or moist. The results showed that thick curls provide the best protection from the sun. Under them, the artificial skin almost did not heat up. Scientists believe that our ancestors in Africa survived, including thanks to their curls: under the burning sun, thick curls helped ancient people retain water in the body longer. "The results of the study do not surprise me. Curls protect the head not only from the scorching sun, but also from the cold. In addition, the scalp is better ventilated. Nowadays, in the summer, this is an ideal image not only for women, but also ... >>

Human embryos are created artificially 28.06.2023

The created embryos are devoid of heart and brain structures, but include cells responsible for the formation of the placenta, yolk sac and the embryo itself. Scientific experts have developed synthetic human embryos using stem cells. This significant achievement opens up new perspectives without the use of eggs and sperm. These models of embryonic structures, which mimic early stages of human development, will help expand our knowledge of genetic disorders and the biological causes of recurrent miscarriages, the researchers say. Although these structures do not have a heartbeat or a developed brain, they include cells normally responsible for the formation of the placenta, the yolk sac, and the embryo itself. However, this discovery raises significant ethical and legal questions, as these created embryos are not subject to the existing laws of most countries in the world.

A new way to split water has been developed 28.06.2023

Hydrogen is a promising energy source of the future, provided that its production is environmentally friendly. In addition, hydrogen plays an important role in the production of active ingredients and other significant substances. However, separating water molecules (H2O) into hydrogen gas (H2) and oxygen is a difficult task for chemists because water molecules are very stable. For successful splitting of water, it is necessary to activate it with a catalyst, which simplifies the reaction. A team of researchers led by Professor Armido Studer from the Institute of Organic Chemistry at the University of Münster (Germany) has developed a photocatalytic process in which water is activated through triarylphosphines, and not through transition metal complexes, as is done in most other processes. This groundbreaking approach, published in the journal Nature, opens the door to active radical chemistry research. Radicals are highly active intermediates ... >>

GPS alternative works even underground 26.06.2023

Researchers from Japan propose a new alternative to the global positioning system (GPS), which will significantly improve the accuracy and expand the ability to navigate even in conditions where being in open space is impossible. Their idea is to use muons - particles that occur when the sun's rays interact with the Earth's atmosphere. Muons are capable of penetrating any solid surface, which means that navigation equipment will function without the need to communicate with satellites in the open. The most surprising thing about this concept of Japanese scientists is that the muon-based wireless navigation system allows you to determine objects even underground and in water. The basic principle of MuWNS (from the English. Muon Wireless Navigation System) is to continuously track the "signals" from muons, which form a continuous "rain" of particles. Every square meter of the Earth's surface is exposed to approximately ... >>

The gel will extract water from the desert air 20.06.2023

MIT scientists have developed an innovative gel capable of extracting incredible amounts of water from the air, even in low-humidity environments like deserts. This hydrogel, created by researchers, has the unique ability to instantly absorb moisture from the air, even at a relative humidity of only 30%. The material effectively retains moisture, preventing it from leaking, and allows it to condense and be collected for use. The synthesized material, which is a transparent and elastic gel, is made from hydrogel, which is already used in products such as disposable diapers due to its ability to absorb moisture. However, the researchers improved this ability by adding lithium chloride, a powerful desiccant. In early experiments, scientists soaked hydrogels in salt water and waited for them to soak up the salt. However, the process was very slow and most experiments took 24 to 48 hours. ... >>

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

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. ... >>

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. ... >>

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 ... >>

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

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. Samsung has worked with Intel on this new standard. The CXL 2.0 DRAM supports PCIe 5.0 and uses 8 lanes. It provides data transfer rates up to 35 Gbps.

This improves overall efficiency and reduces operating costs. So far, such memory is intended only for use in server systems. Manufacturers are still working on consumer grade CXL memory. Samsung has announced that it intends to start mass production of CXL 2.0 DRAM memory in ... >>

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. ... >>

Radically modular electric bike Fabriga Modula 07.05.2023

Cargo e-bikes are a great alternative to cars, but the needs of an e-bike rider can certainly change afterwards. This is where the Fabriga Modula e-bike comes in and can be adapted to the changing needs of users. The Modula, recently unveiled at the Cargo Bike Summit in London, is made by Italian electric bike manufacturer Fabriga. The Modula frame consists of three sections, fastened with screws: the steering part (front wheel and handlebar); motor part with engine and rear part. The front section for all configurations of the bike remains unchanged, but the propulsion inside can be equipped with Brose motors of different power, depending on the weight of the cargo being transported. You can do without an engine if the owner likes to pedal the old way. The most different section is the back. In particular, a wide and flat cargo platform can be installed on it; place over the rear wheel long ... >>

Created the collective genome of humanity 06.05.2023

Scientists have compiled the world's first human pangen - a database of all the genes and genetic variations of the human population. This will help track DNA variations that cause rare genetic diseases and create effective treatments. The researchers included the complete genomes of 47 people from different ethnic and racial groups. Human genomes are 99% identical, and it is the last percentage that makes us unique. To study the uniqueness of each person, such as their diseases, scientists will use this new genetic base. With its help, it will be possible to predict hereditary diseases and prevent them.

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 ... >>

Innovative orbital housing concept from Airbus 04.05.2023

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. ... >>

Tests of the suborbital space plane SpaceShipTwo 27.04.2023

SpaceShipTwo yesterday completed the first flight in two years that Virgin Galactic has flown in preparation for commercial service. Virgin Galactic has been developing and testing a system of carrier aircraft and SpaceShips to provide space tourism services since the early 2000s. The prototype SpaceShipOne spaceplane made its first flight in 2003, and in 2010 the SpaceShipTwo spaceplane, called the VSS Enterprise, took off for the first time. In the future, all test flights were carried out with the participation of VSS Unity, which was created to replace the first one that crashed during testing in 2014. Recently, VSS Unity was once again taken to the skies by the carrier aircraft VMS Eve (each vehicle had two pilots) from the America Spaceport in New Mexico. Unity separated from the carrier at an altitude of 14 meters and began flying along the glide path to the runway, where it landed in 300 minutes. This flight test was the first for VSS Unity since ... >>

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. ... >>

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. ... >>

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. "This rule is valid for its intended purpose, that is, if the Platio solar pavers are not subjected to a pressure of more than 2 tons. Therefore, it is safe to walk on it." The solar path consists of 2544 solar pavements. It will generate 55 kWh of electricity per year to power Groningen City Hall. The Platio solar paving stone consists of four monocrystalline parts with a power of 000W and an efficiency of 21,5%. The open circuit voltage is 21,8V and the short circuit current is 2,69A.

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 ... >>

Cellulose Water Purification 03.04.2023

Researchers at the Swedish Chalmers University of Technology have invented a new way to purify polluted water using cellulose-based materials. This breakthrough could have a significant impact in regions where water treatment technologies are inadequate and help address the widespread problem of toxic dye emissions from the textile industry. Access to clean water is essential to our health and well-being, but it remains a challenge for many. The World Health Organization (WHO) reports that more than two billion people currently live without access to clean water. This global problem is at the center of a research team at Chalmers University of Technology who have developed a method to easily remove contaminants from water. The group, led by Gunnar Westman, Associate Professor of Organic Chemistry, focuses on new uses for cellulose and wood-based products and is part of the Wallenberg Science Center and ... >>

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. ... >>

New frost-resistant raspberry variety with high keeping quality 31.03.2023

The Institute of Horticulture of Poland has developed a dessert raspberry variety Skierka, which bears fruit on one-year and two-year-old shoots. The new variety is distinguished by good taste of berries and high yield. Breeders advise growing it both on commercial plantations and in home gardens. On annual shoots, the first berries begin to ripen around mid-August, and the last - until the autumn frosts.

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 ... >>

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 ... >>

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

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 ... >>
