Tech Xplore / AI agents struggle to perform original scientific research
Among the many predictions about the future of artificial intelligence is that models will one day be able to conduct scientific research on their own, leaving humans out of the equation. Already, they can write code, run ...
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 ...
Phys.org / Guangzhou crucibles provide earliest direct evidence of brass-making in East Asia
For centuries, scholars have read ancient documents describing the production of brass in 10th-century A.D. China. The problem was that the earliest physical evidence of brass production would be found nearly 600 years later, ...
Medical Xpress / Curiosity has its own neural signal: Brain separates valuable information from water rewards in mice
Often, humans and other animals seek information that can help them complete tasks and attain desired rewards. In some cases, however, they seek information driven simply by curiosity and a desire to obtain knowledge for ...
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 ...
Phys.org / Twisted magnetic field around newborn star confirms decades-old jet theory
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) is a partner, have captured the first direct, high-resolution ...
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 / 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 ...
Medical Xpress / Researchers examine unanticipated benefits of GLP-1 medications
GLP-1 receptor agonists and dual agonists have transformed the treatment of obesity and other metabolic diseases, and a new editorial co-authored by Dr. Steven Heymsfield of LSU's Pennington Biomedical Research Center and ...
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 / 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" ...
Phys.org / New findings overturn 100-year-old assumption about common bacteria in the lungs
The human body is teeming with more than 35 trillion bacteria, coexisting in microbiomes inside the gut, mouth, lungs, skin and urogenital tract. While it's now clear these microbes are associated with health and disease, ...
