At just two months old, babies are already organizing the world in their minds. Brain scans revealed distinct patterns as infants looked at pictures of animals, toys, and everyday objects, showing early category recognition. Scientists used AI to ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them promising for wireless data transmission. Using a ...

As bird flu continues to circulate in animals and spill over into humans, researchers are racing to stop it before it adapts to spread widely between people. A new nasal spray vaccine showed strong protection against H5N1 in animal tests, ...

Popular weight-loss drugs like Ozempic and Wegovy can dramatically curb appetite, but experts warn many users are flying blind when it comes to nutrition. New research suggests people taking these medications may not be getting enough guidance on ...

A massive Swedish study tracking nearly 28,000 people for 25 years found an unexpected link between full-fat dairy and brain health. Among adults without a genetic risk for Alzheimer's, eating more full-fat cheese was associated with a noticeably ...

Scientists still don't know how the brain turns physical activity into thoughts, feelings, and awareness--but a powerful new tool may help crack the mystery. Researchers at MIT are exploring transcranial focused ultrasound, a noninvasive technology . ...

Melting ice from West Antarctica once delivered huge amounts of iron to the Southern Ocean, but algae growth did not increase as expected. Researchers found the iron was in a form that marine life could not easily use. This means more melting ice ...

Scientists are digging into why heart disease risk in type 2 diabetes differs between men and women--and sex hormones may be part of the story. In a large Johns Hopkins study, men with higher testosterone had lower heart disease risk, while rising .. ...

Scientists have uncovered a surprising genetic shift that may explain how animals with backbones--from fish and frogs to humans--became so complex. By comparing sea squirts, lampreys, and frogs, researchers found that key genes controlling cell ...

Sound machines may not be the sleep saviors many believe. Researchers found that pink noise significantly reduced REM sleep, while simple earplugs did a better job protecting deep, restorative sleep from traffic noise. When pink noise was combined .. ...
