Phys.org / Machine learning helps solve a central problem of quantum chemistry
By applying new methods of machine learning to quantum chemistry research, Heidelberg University scientists have made significant strides in computational chemistry. They have achieved a major breakthrough toward solving ...
Phys.org / Antarctic warming is altering atmospheric stability: New evidence from the 1950s to the present
A new study published in the Journal of Climate reveals how surface warming in Antarctica, particularly over the Antarctic Peninsula, is significantly altering the stability of the lowest layers of the atmosphere.
Phys.org / From power grids to epidemics: Study shows how small patterns trigger systemic failures
Why do some systems collapse suddenly after what seems like a minor disturbance? A single transmission line failure can cascade into widespread blackouts. A delayed shipment can ripple through a global supply chain, emptying ...
Tech Xplore / Personalization features can make LLMs more agreeable, potentially creating a virtual echo chamber
Many of the latest large language models (LLMs) are designed to remember details from past conversations or store user profiles, enabling these models to personalize responses. But researchers from MIT and Penn State University ...
Phys.org / Indigenous Peoples and locals report a drastic decline in bird size across three continents
Birds currently inhabiting many territories across Africa, Latin America and Asia are, on average, considerably smaller than those that predominated in 1940. This is the conclusion of an international study led by the Institute ...
Phys.org / Quantum simulator reveals statistical localization that keeps most qubit states frozen
In the everyday world, governed by classical physics, the concept of equilibrium reigns. If you put a drop of ink into water, it will eventually evenly mix. If you put a glass of ice water on the kitchen table, it will eventually ...
Medical Xpress / People prefer the empathy of humans, but rate 'fake' AI empathy higher
Artificial Intelligence (AI) agents, particularly the large language models (LLMs) underpinning the functioning of ChatGPT and other popular conversational platforms, are now used daily by millions of people worldwide. As ...
Medical Xpress / Kirigami-inspired sensors precisely map activity of neurons in the primate brain
Recent technological advances have opened new exciting possibilities for the development of smart prosthetics, such as artificial limbs, joints or organs that can replace injured, damaged or amputated body parts. These same ...
Medical Xpress / Scientists find a mechanism showing how exercise protects the brain
Researchers at UC San Francisco have discovered a mechanism that could explain how exercise improves cognition by shoring up the brain's protective barrier. With age, the network of blood vessels—called the blood–brain ...
Phys.org / 'Boomerang' earthquake simulations suggest ricocheting ruptures may be more common than previously thought
An earthquake typically sets off ruptures that ripple out from its underground origins. But on rare occasions, seismologists have observed quakes that reverse course, further shaking up areas that they passed through only ...
Medical Xpress / Scientists discover 'bacterial constipation,' a new disease caused by gut-drying bacteria
Scientists at Nagoya University in Japan have found two gut bacteria working together that contribute to chronic constipation. The duo, Akkermansia muciniphila and Bacteroides thetaiotaomicron, destroy the intestinal mucus ...
Phys.org / Map suggests up to 30% of western bird hotspots face severe wildfire risk
Up to 30% of bird diversity hotspots, places where large numbers of different bird species occur, in the western United States face threats from high-severity wildfires in the future that could eliminate critical forest habitats, ...
