Advanced care provided by air ambulance teams was linked to higher survival rates in major trauma patients. Researchers found that more people survived than predicted by standard models, including many with severe injuries and low chances of survival ...

A new metasurface design lets light of different spins bend, focus, and behave independently--while staying sharp across many colors. The trick combines two geometric phase effects so each spin channel can be tuned without interfering with the other. ...

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 .. ...
