Phys.org / Atomic reshuffle leads to record-breaking catalysts for hydrogen production
Researchers have discovered that atoms can be mixed, separated, and recombined within the same experiment, providing a pathway to a record-breaking catalyst for green hydrogen production. In their study, the team created ...
Phys.org / First deliberately injured Langobard woman in skeletal record reshapes view of male-only violence
The Langobards are frequently depicted as fierce warrior-like people, with all known archaeological evidence of violence restricted to men. However, nearly 1,400 years ago, a Langobard woman took two severe injuries to the ...
Phys.org / Cells have a built-in 'seatbelt' against sudden stress
When cells experience sudden physical stress, like stretching or pressure, they can activate a fast, protective mechanism that shields their nuclei from destruction, according to a new study published in the Biophysical Journal. ...
Phys.org / A giant star may have destroyed itself in one of the universe's rarest explosions
Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in the universe, leaving ...
Medical Xpress / Engineered Salmonella deliver cancer-killing viruses, shrinking liver and pancreatic tumors in mice
Researchers at the University of Massachusetts Amherst have designed non-toxic Salmonella bacteria to deliver viruses that are safe to humans but potent against liver and pancreatic cancer tumors—two cancers with an extremely ...
Phys.org / Dead Sea archaea sport reinforced swimming tail for hypersalty waters
Living in the Dead Sea would be a very unpleasant experience for most creatures. With salt concentration above 30% and temperatures ranging from 10–50°C, it takes unique environmental adaptations to survive in such harsh ...
Phys.org / Q&A: Why scientists are studying a microbe they found in a sink
Scientists commonly use bacteria as tiny factories that can produce molecules for uses ranging from drug development to pollution remediation. Recently, NC State biologist Carlos Goller and former undergraduate students Pushkar ...
Medical Xpress / Unexpected chromosome interaction fuels aggressive cancers, researchers discover
Published in Nature, researchers at the University of Pittsburgh School of Medicine and UPMC Hillman Cancer Center report a previously unrecognized change in how the cell's genetic material is packaged into structures called ...
Medical Xpress / Women with kidney disease are undertested, undertreated and left behind by decades of male-dominated research
Women with chronic kidney disease are less likely than men to be diagnosed, represented in research and given treatments that have been properly tested in them. That is the central finding of a new paper published today in ...
Phys.org / Tiny-armed alvarezsauroid dinosaurs might have been insect eaters, fossil scans suggest
Dinosaurs are estimated to have roamed Earth for over 165 million years, gradually evolving over time to survive in changing environments. Among the many fascinating groups of dinosaurs known to have lived on our planet are ...
Medical Xpress / Largest study of knee osteoarthritis tissue reveals core biological pathways underlying the disease
A major international study led by researchers at the Kennedy Institute of Rheumatology at the University of Oxford has found that osteoarthritis (OA)—the most common form of arthritis worldwide—is not a collection of separate ...
Science X / Friendly AI may backfire when its tone doesn't match the moral dilemma
AI chatbots have become friends, confidants, even professional and health advisors for many people around the world. While the long-term consequences remain debated, it has become an undeniable reality of the ChatGPT era. ...
