Phys.org / Ion bombardment triggers a reliable quantum switch in tantalum disulfide crystals
When you toss a coin, you put it into a higher-energy state until it falls back down again. It can then end up in one of two possible states: heads or tails. No matter which state the coin was in before, after the toss both ...
Phys.org / The physics of sneaker squeaks: High-speed imaging shows how they arise from supersonic detachment pulses
Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or a cycle of intermittent ...
Tech Xplore / How AI could help make society less selfish
The Care Bears taught a generation of kids that sharing is caring, but not everyone has carried this principle into adulthood. Researchers at Michigan State University have found a new angle to promote cooperation: artificial ...
Phys.org / First cases of highly pathogenic avian influenza in northern elephant seals confirmed in California
Seven weaned elephant seal pups in California's Año Nuevo State Park tested positive for highly pathogenic avian influenza (HPAI) H5N1, the U.S. Department of Agriculture's National Veterinary Services Laboratory confirmed ...
Phys.org / Fast-paced lives demand faster vision: Ecology shapes how 'quickly' animals see time
Animals don't just see the world differently from one another, they experience time itself at dramatically different speeds. That is according to a new study that considered 237 species across the animal kingdom, and which ...
Phys.org / Diamond surfaces are covered in thin, ice-like water layers
Using atomic-scale defects in diamond, researchers in China have gained unprecedented insights into the complex chemical processes that unfold at the interfaces between solid surfaces and their surroundings. Published in ...
Medical Xpress / How ketogenic diets help prevent seizures
A ketogenic diet—one that is high in fat and extremely low in carbohydrates—has been known for decades to reduce seizures in some epilepsy patients. But how the highly restrictive diet achieves these effects has not previously ...
Tech Xplore / HEART benchmark assesses ability of LLMs and humans to offer emotional support
Large language models (LLMs), artificial intelligence (AI) systems that can process human language and generate texts in response to specific user queries, are now used daily by a growing number of people worldwide. While ...
Medical Xpress / Differing immune responses in infants may explain increased severity of RSV over SARS-CoV-2
Young infants hospitalized with respiratory syncytial virus (RSV) often become much sicker than those infected with SARS-CoV-2, the virus that causes COVID-19. In a study published in Science Translational Medicine, scientists ...
Phys.org / AI gets water right: How a hydration shield helps proteins keep their shape
A study published in the Journal of the American Chemical Society reports that artificial intelligence can enhance protein stability in an unexpected way—by engineering the water around a protein, not just the protein itself. ...
Phys.org / New michelin star jellyfish discovered in Japanese aquaria
Researchers have reported the discovery of a new species of jellyfish, Malagazzia michelin, marking only the second species of its genus ever found in Japanese waters. Led by Takato Izumi of Fukuyama University, the discovery ...
Medical Xpress / Superagers' brains have a 'resilience signature,' and it's all about neuron growth
Brains of older adults with super-healthy cognition grow more new neurons than those of their peers, according to a study from UIC, Northwestern University and the University of Washington. Researchers found that the brains ...
