Seemingly spontaneously coordinated swarm behaviour exhibited by large groups of animals is a fascinating and striking collective phenomenon. Experiments conducted by researchers at Leipzig University on laser-controlled synthetic microswimmers now show that supposed swarm intelligence can sometimes also be the result of simple and generic physical mechanisms. A team of…
When people are in a negative mood, they may be quicker to spot inconsistencies in things they read, a new University of Arizona-led study suggests. The study, published in Frontiers in Communication, builds on existing research on how the brain processes language. Vicky Lai, a UArizona assistant professor of psychology…
When genes are activated and expressed, they show patterns in cells that are similar in type and function across tissues and organs. Discovering these patterns improves our understanding of cells — which has implications for unveiling disease mechanisms. The advent of spatial transcriptomics technologies has allowed researchers to observe gene…
Clean energy is the leading solution for climate change. But solar and wind power are inconsistent at producing enough energy for a reliable power grid. Alternatively, lithium-ion batteries can store energy but are a limited resource. “The advantage of a coal power plant is it’s very steady,” said Nian Liu,…
Chemicals that accumulate in the vagina, potentially originating from personal care products, may contribute to spontaneous preterm birth, according to a new study by researchers at Columbia University Vagelos College of Physicians and Surgeons. The study of 232 pregnant women found that a handful of non-biological chemicals previously found in…
Using artificial intelligence, Cornell University engineers have simplified and reinforced models that accurately calculate the fine particulate matter (PM2.5) — the soot, dust and exhaust emitted by trucks and cars that get into human lungs — contained in urban air pollution. Now, city planners and government health officials can obtain…
It seems logical enough that bad weather can sometimes cause birds to become disoriented during their annual fall migrations — causing them to wind up in territory they’re unaccustomed to. But why, even when weather is not a major factor, do birds travel far away from their usual routes? A…
Understanding how dust grains form in interstellar gas could offer significant insights to astronomers and help materials scientists develop useful nanoparticles. Laboratory and rocket-borne studies have revealed new insights into how interstellar dust grains came into being before our solar system formed. The results, published by Hokkaido University researchers and…
Chemists from the University of Groningen have found a simple way to produce previously inaccessible chiral Z-alkenes, molecules that offer a significant synthetic short-cut for the production of bioactive molecules. Instead of eight to ten synthetic steps to produce these molecules, the new reaction can be done in three steps,…
Scientists from the Institut Pasteur, Université Paris Cité, the CNRS and the Collège de France have used paleogenomics to trace 10,000 years of human immune system evolution. They analyzed the genomes of more than 2,800 individuals who lived in Europe over the past ten millennia. They were able to date…
In the past decade, researchers have begun to appreciate the importance of a two-way communication that occurs between microbes in the gastrointestinal tract and the brain, known as the gut-brain axis. These “conversations” can modify how these organs work and involve a complex network of microbe- and brain-derived chemical signals…
New York CNN — The Trump Organization was fined $1.6 million – the maximum possible penalty – by a New York judge Friday for running a decade-long tax fraud scheme, a symbolic moment because it is the only judgment for a criminal conviction that has come close to former President…
Wagner, the Russian private military company, posted a video on Telegram Thursday evening directly disparaging the Russian defense ministry’s claim that regular Russian military forces have participated in the assault on Soledar. A day after Russia’s defense ministry reshuffled the command of its so-called “special military operation,” Wagner’s post doubled down on the…

The conversion of solar energy into hydrogen energy represents a promising and green technique for addressing the energy shortage and reducing fossil fuel emissions. A research team from City University of Hong Kong (CityU) recently developed a lead-free perovskite photocatalyst that delivers highly efficient solar energy-to-hydrogen conversion. Most importantly, they…
Madagascar is home to a unique biodiversity with a large number of endemic species, among those many lemur species, including the mouse lemurs. This diversity is also found in their retroviruses, a team led by scientists from the Leibniz Institute of Zoo and Wildlife Research (Leibniz-IZW) and the University of…
Earth’s average surface temperature in 2022 tied with 2015 as the fifth warmest on record, according to an analysis by NASA. Continuing the planet’s long-term warming trend, global temperatures in 2022 were 1.6 degrees Fahrenheit (0.89 degrees Celsius) above the average for NASA’s baseline period (1951-1980), scientists from NASA’s Goddard…
Scientists have decoded the physical process that takes place in the mouth when a piece of chocolate is eaten, as it changes from a solid into a smooth emulsion that many people find totally irresistible. By analysing each of the steps, the interdisciplinary research team at the University of Leeds…
An international team of researchers including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has studied the relation between galaxy size and luminosity of some of the earliest galaxies in the universe taken by the brand-new James Webb Space Telescope (JWST), less than a billion…
A group of researchers has identified the key stumbling block of a common solid-state hydrogen material, paving the way for future design guidelines and widespread commercial use. Details of their findings were published in the Journal of Materials Chemistry A, where the article was featured as a Front Cover Article.…
We are all familiar with robots equipped with moving arms. They stand in factory halls, perform mechanical work and can be programmed. A single robot can be used to carry out a variety of tasks. Until today, miniature systems that transport miniscule amounts of liquid through fine capillaries have had…
Negative emotions, anxiety and depression are thought to promote the onset of neurodegenerative diseases and dementia. But what is their impact on the brain and can their deleterious effects be limited? Neuroscientists at the University of Geneva (UNIGE) observed the activation of the brains of young and older adults when…
Birds fly more efficiently by folding their wings during the upstroke, according to a recent study led by Lund University in Sweden. The results could mean that wing-folding is the next step in increasing the propulsive and aerodynamic efficiency of flapping drones. Even the precursors to birds — extinct bird-like…
Hearing loss cases are climbing globally — 1 in 5 adults are affected — along with a growing number of older workers who are more likely to experience hearing loss. A new study from researchers at Portland State, Oregon State and York universities sheds light on how the severity of…
Reaching out to support a person when they’re under stress is always a good idea. But a new study suggests that support could be especially important for someone whose genetic makeup makes them more likely to develop depression. The study shows the importance of social support in buffering the risk…
Ukrainian troops still on edge of Soledar, a soldier tells CNN Source link
CNN — A US carrier strike group began operating in the South China Sea on Thursday, the Navy announced, amid heightened tensions with Beijing, which claims much of the body of water as its sovereign territory. Two Chinese ships are already tailing the US group, a defense official told CNN,…
CNN — Russia said Friday its forces have taken the town of Soledar in eastern Ukraine following weeks of fierce fighting, in what would be Moscow’s first significant victory in months. Ukraine’s armed forces have denied Moscow’s claim. Serhiy Cherevaty, a spokesman for the Eastern Group of the Armed Forces…
