Scientists discovered that kombucha’s flavor, chemistry, and antioxidant activity vary dramatically depending on the tea used to make it. Green and oolong tea kombuchas emerged as the most biologically active, while fermentation transformed each tea in…

SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference. Even so, the rapid-response observations helped confirm the object’s natural o…

Researchers uncovered why H5N1 bird flu attacks cows’ udders instead of their lungs: the virus’s preferred receptors are concentrated in mammary tissue. The breakthrough could help scientists predict future bird flu jumps and spot unusual infections be…

A bird long thought to be a single rare species in Japan has turned out to be two. Scientists discovered that the elusive Ijima’s Leaf Warbler and a newly identified Tokara Leaf Warbler look almost identical, but their DNA and songs reveal they are dis…

A newly discovered feathered dinosaur called Jian changmaensis may be the missing predator responsible for mysterious piles of crushed prehistoric bird bones in China. The four-winged glider, a close cousin of Velociraptor, helps reveal how early birds…

For decades, scientists thought royal jelly was the secret ingredient that turned an ordinary honeybee larva into a queen. New research reveals the process is far more remarkable: young worker bees create special “royal cribs” made from customized wax,…

A newly proposed quantum sensing technique could make it much easier to identify one of physics’ newest and most intriguing classes of magnets: altermagnets. These unusual materials, discovered only a few years ago, appear to combine the speed and effi…

A new study suggests that learning and remembering speech relies more on how the brain processes sounds and sensations than on the areas that control mouth and face movements. The discovery could reshape speech therapy and help improve future brain-bas…

Researchers found that highly drug-resistant bacteria from hospitals are also resistant to glyphosate, a commonly used weedkiller. The discovery suggests that agricultural herbicides may be helping antibiotic-resistant microbes survive and spread far b…

A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō. The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife …

A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision. The discovery suggests some early planets formed from dramatically different materials than Earth and Mar…

NASA’s upgraded Cold Atom Lab is turning the International Space Station into a frontier for quantum research, creating ultra-cold matter that behaves in astonishing ways. The experiments could unlock new discoveries about the universe while paving the…

A minimally invasive treatment called GAE is helping people with chronic knee pain get back to gardening, cycling, and other activities without undergoing knee replacement surgery. Early studies suggest the procedure can provide years of relief by redu…

A new review suggests that doing more exercise and eating more protein than current minimum recommendations may help people stay stronger, sharper, and more independent as they age. The goal isn’t building a beach body—it’s extending healthspan and mai…
