Phys.org / Quantum metallurgy: Electron crystals deform and melt
In a process analogous to how solids melt into liquids, the electrons in many different metals form crystal-like patterns that can deform and melt, opening new pathways for neuromorphic computing and superconductors, University ...
Medical Xpress / Solving a 15-year mystery: Scientists discover how gut bacteria toxin invades colon cells to trigger cancer
Since a landmark 2009 study, researchers have known that a common gut bacterium, Bacteroides fragilis, drives colon tumor formation, potentially leading to colorectal cancer, by secreting a toxin that damages the lining of ...
Medical Xpress / One powerful treatment, two opposite outcomes: Psychedelic therapy may heal some patients while deeply unsettling others
Psychedelic-assisted therapy is the subject of renewed focus. It involves using psilocybin—a substance found in psychoactive fungi—or LSD to treat mental disorders. Numerous studies are currently underway, with talk rife ...
Phys.org / Streetlights trigger bizarre 'death spirals' in thousands of isopods, scientists find
A new study led by Ph.D. student Idan Sheizaf, under the guidance of Prof. Ariel Chipman from The Hebrew University of Jerusalem, has documented a never-before-seen behavioral phenomenon: thousands of land-dwelling isopods ...
Tech Xplore / Focused helium ions create ferroelectric regions in aluminum nitride for lower-power chips
Scientists at the Department of Energy's Oak Ridge National Laboratory have shown for the first time that ferroelectricity can be directly written into aluminum nitride using a tightly focused helium ion beam at the Center ...
Science X / This volcano didn't just erupt—it triggered a hidden atmospheric cleanup scientists never expected to see
When the submarine volcano Hunga Tonga–Hunga Ha'apai in the South Pacific erupted in January 2022, it was not only one of the most violent volcanic eruptions in modern times. The volcano also did something completely unexpected: ...
Medical Xpress / High-fat diets during pregnancy may worsen severe GI illness in preterm babies
A new mouse study led by Johns Hopkins Children's Center researchers suggests a link between a high-fat prenatal diet and induction of potentially deadly symptoms of necrotizing enterocolitis (NEC) in premature babies. Findings ...
Medical Xpress / Study finds no benefit to miniature heart pump during complex stent procedures
Results from the first randomized trial of Impella pumps during complex stent procedures, published in the New England Journal of Medicine, have shown that the pumps offer no significant benefit to patients compared to standard ...
Dialog / Scientists uncover hidden parasite diversity in barb fish from the Sea of Galilee
When most people think about biodiversity in lakes and rivers, they imagine fish, plants, or perhaps birds and amphibians. But beneath the surface exists another world that often goes unnoticed: microscopic parasites that ...
Phys.org / Pilot whales are already 'shouting' at full volume, but one busy waterway is pushing them to the edge
With over 60,000 ships passing through the Strait of Gibraltar each year, this stretch between the Atlantic and Mediterranean is one of the busiest waterways on the planet. This narrow strip of water is also home to a critically ...
Phys.org / The 'nostalgia effect': Scientists produce less disruptive work as they age
You probably know that Einstein changed the face of physics with his theory of relativity in his twenties. What you may not know is that he spent his later career on a crusade against quantum mechanics, the model that would ...
Medical Xpress / AI language models struggle with basic hospital data tasks, study finds
A new study finds that large language models (LLMs), used with straightforward prompting, perform poorly on routine number-crunching tasks that hospital administrators depend on every day to track patients and allocate resources. ...
