Phys.org / Star cluster discovery could change how scientists measure the universe
University of Missouri researchers have uncovered evidence that challenges one of astronomy's most trusted assumptions, a breakthrough that could reshape how scientists measure galaxies and reconstruct the history of the ...
Phys.org / Quantum Latin squares cannot solve Euler's 36 officers problem without entanglement
Latin squares are arrangements of symbols in a grid in which every symbol appears exactly once in each row and column. These symbol arrangements, which were first studied more than three centuries ago, are now widely used ...
Medical Xpress / Professor becomes his own test subject in longevity study; biological age found to be 15 years younger
Most individuals encounter their health primarily through an annual health screening, which provides a limited snapshot of their health status. A new study by the Yong Loo Lin School of Medicine, National University of Singapore ...
Phys.org / Human blood may have helped preserve ancient Chinese rock art for 2,000 years
The Huashan rock art landscape in southern China, close to the border with Vietnam, is a remarkable UNESCO World Heritage site. Thousands of images are painted on river cliffs across more than 80 locations stretching 260 ...
Phys.org / Rings forged from meteorites may have been fashionable among ancient Greek elites
Meteorites provided a rare but ready source of iron for ancient Bronze Age cultures before smelting became common. A new study, published in the Journal of Archaeological Science, sheds light on how the ancient Minoan and ...
Phys.org / Quality vs. quantity: Why 'super-shedders' may not be the superspreaders of disease outbreaks
A host that sheds an abundance of parasites might seem like an obvious disease-spreading threat. But new research suggests that shedding large volumes of parasites does not dictate transmission efficiency—and "super-shedders" ...
Medical Xpress / New gas-switching approach could one day make deep-sea decompression safer and faster
Deep-sea divers must be careful to prevent decompression sickness, also known as "the bends," when ascending from the high-pressure depths of the ocean. Failing to do so can result in anything from muscle cramps and skin ...
Tech Xplore / Should people marry AI agents?
The widespread use of conversational platforms such as ChatGPT and Gemini is raising important new ethical, anthropological and legal questions regarding the potential risks, misuses and shortcomings of artificial intelligence ...
Phys.org / Early hardship may shape how oxytocin influences altruism
While humans are inherently social beings, they can interact and connect with others in very different ways. For instance, while some people tend to be more altruistic, others are less prone to helping their friends, acquaintances ...

As temperatures continue to soar and amber heat-health alerts are issued across England, warnings are reaching the public but still failing to change behavior. A new investigation by United Nations University experts finds ...
Medical Xpress / Adults 75 and older who stopped statins had similar three-year survival, trial finds
Stopping statins in adults 75 and older with no history of heart disease or stroke does not increase the risk of death over three years compared with continuing statins, although "bad" cholesterol rose around 50% in those ...
Phys.org / Mars could have carried liquid water more recently than we thought
For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked ...
