Researchers found that semaglutide, the active ingredient in Ozempic and Wegovy, slowed biological aging markers in adults with HIV, marking the first clinical evidence that the drug may influence human aging。 Although the findings are encouraging, scientists say larger studies are needed before concluding that the medication can help people age mo
A new experimental treatment may have found a way to outsmart glioblastoma’s toughest defense: the blood-brain barrier。 Researchers used sugar-coated nanoparticles to ferry genetic instructions that restore a key tumor-suppressing protein directly into brain cancer cells。 In mouse studies, the therapy increased median survival by 50% while shrinkin
A powerful new AI tool has uncovered what could be one of the biggest integrity problems in modern science。 After analyzing 2。6 million cancer research papers published between 1999 and 2024, researchers identified more than 250,000 studies with writing patterns resembling papers suspected of being produced by fraudulent "paper mills
Ancient DNA from China’s vast 4,000-year-old Shimao settlement is revealing how one of East Asia’s earliest complex societies was organized。 Researchers found that its people were largely descended from local Yellow River farming communities, but also had genetic ties to distant southern and steppe populations, pointing to extensive prehistoric con
A major DNA study has rewritten the koala's evolutionary story, revealing that the species suffered a dramatic population collapse about 100,000 years ago, long before humans arrived in Australia。 By calculating the koala's mutation rate for the first time and analyzing hundreds of genomes, researchers discovered that every living koala traces back
A deadly fungus has wiped out amphibian populations around the globe, yet some mysteriously recover。 Researchers discovered that survivors develop powerful immune defenses while they are still tadpoles, giving them a head start before the fungus can attack after metamorphosis。 The study also uncovered a vast collection of previously unknown antimic
Dying Sun-like stars may not fade away quietly。 As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction。 Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive two stars into a violent collision
More than one-eighth of apps analyzed contained foreign code
NASA has chosen 41 commercial technology projects that could solve critical challenges for future missions to the Moon and Mars。 From powering lunar outposts to protecting spacecraft from Moon dust, the innovations are designed to push both space exploration and the commercial space economy forward
Pennsylvania cop charged with oppression and obstruction
A new particle detector called PLATON could replace millions of tiny detector components with a single block of light-producing material。 Using a light-field camera, highly sensitive photon sensors, and AI, it reconstructs particle paths in fast, detailed 3D。 Simulations suggest it could match or surpass today’s best detectors while being far easie
Several popular sugar substitutes may not be as harmless as they seem。 Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes。 The highest intake was linked to cognitive aging roughly 1
The Trump administration is asking the Space Force to do a lot。 This will require more launches
Scientists have developed a new framework that could finally apply the laws of thermodynamics to real, ever-changing black holes instead of only perfectly stable ones。 The advance may improve our understanding of black hole mergers, evaporation, and the powerful gravitational wave events detected by observatories like LIGO
NatGeo's Pompeii: Out of Time fuses historical fact and imagination to bring city's last 24 hours to life
NASA's James Webb Space Telescope has revealed new details about the blistering lava planet 55 Cancri e, where temperatures are high enough to melt rock。 The data indicate the planet likely has a hydrogen-rich atmosphere shaped by gases escaping from its molten interior, with signs that volcanic outgassing may even create temporary clouds
NASA's PACE satellite captured the Black Sea glowing turquoise during its annual phytoplankton bloom。 The vivid color comes from massive numbers of coccolithophores, microscopic organisms whose reflective shells brighten the water enough to be seen from space。 An astronaut aboard the International Space Station also photographed the bloom spreading
Ronald Fischer, aka Richard Graydon, was arrested in New York last week
K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes。 Advanced software analyzed millions of signals, filtering out Earth-based interference and other false positives。 No convincing artificial radio transmissions wer
Automakers love connected vehicles, but support isn't open-ended
