Phys.org / Cold fronts in nearby galaxy group may redistribute metals, Chandra and GMRT data reveal
Astronomers from South Africa and India have analyzed archival data from the Chandra X-ray Observatory and Giant Metrewave Radio Telescope (GMRT) regarding a nearby small galaxy group known as IC 1262. Results of the new ...
Phys.org / Laser-plasma 'mirror' unlocks a new path to extreme light intensities
An international team of physicists has achieved a significant advance in laser science, demonstrating for the first time a practical route to dramatically boosting the intensity of high-power laser light.
Tech Xplore / Generative AI may cut costs in machine-learning systems, but it increases risks of cyberattacks and data leaks
Using generative AI to design, train, or perform steps within a machine-learning system is risky, argues computer scientist Micheal Lones in a paper appearing in Patterns. Though large language models (LLMs) could expand ...
Phys.org / How cells turn mechanical forces into biochemical signals
Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response to its environment is always biochemical, mediated by the chemistry of its internal protein machinery. ...
Medical Xpress / Bat coronavirus reveals a new way into human cells, widening the map of future spillover risks
An international team of researchers has identified an East African bat coronavirus capable of entering human cells. While the virus—Cardioderma cor coronavirus (CcCoV) KY43, or CcCoV-KY43—can bind to a cell receptor found ...
Medical Xpress / Tourette's tics are not just motor misfires—an emotion-linked brain circuit may open a new treatment frontier
While tics have been considered to result from an aberrant function of the brain's motor cortex, a Kobe University mouse study has now discovered a connection to the brain's emotional functions. The result promises a new ...
Phys.org / A vast Indigenous American genome map exposes lost migrations, ancient ancestry and more than a million new variants
Research into human genomic diversity has a number of applications in biomedicine, evolution, and history. However, many populations have historically been underrepresented on the human genomic map. This is the case of Native ...
Medical Xpress / Hearing restoration lasts years after gene therapy for inherited deafness, new trial results show
A new international study co-led by investigators from Mass General Brigham and the Eye & ENT Hospital of Fudan University shows that a gene therapy for a rare form of genetic deafness successfully restored hearing in most ...
Medical Xpress / Brain support cells form a previously unknown network
Cells long thought to play a secondary role in brain function build their own far-reaching connections, according to a new study in mice. These pathways appear to connect distant regions in ways that had not been mapped before. ...
Medical Xpress / America's fastest-growing sport has an eye injury problem few older players see coming
Pickleball-related eye injuries are on the rise in the United States, according to a study published in the journal Eye and led by Houston Methodist. The findings underscore a public health concern tied to one of America's ...
Tech Xplore / Making big tech algorithms 'fair' is harder than it looks
Before big tech engineers can improve the fairness of recommendation systems, such as social media feeds and online shopping results, they need to define what "fairness" even means. Should an app show people only the content ...
Phys.org / NASA's Curiosity rover uncovers metal‑rich hotspot tied to ancient Martian lake
A team of scientists using the ChemCam instrument on NASA's Curiosity Mars rover has discovered the highest amounts of iron, manganese, and zinc ever found together in Gale Crater on Mars. Minerals with these metals were ...
