Voyager 2's flyby of Uranus in 1986 recorded radiation levels so extreme they baffled scientists for nearly 40 years. New research suggests the spacecraft caught Uranus during a rare solar wind event that flooded the planet's radiation belts with ...

Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to anchor our galaxy, explaining both the blistering speeds of stars near the center and the slower, graceful rotation of ...

Scientists have cracked a key mystery behind spider silk's legendary strength and flexibility. They discovered that tiny molecular interactions act like natural glue, holding silk proteins together as they transform from liquid into incredibly tough ...

New simulations reveal that both H1N1 and COVID-19 spread across U.S. cities in a matter of weeks, often before officials realized what was happening. Major travel hubs helped drive rapid nationwide transmission, with air travel playing a bigger role ...

For decades, Americans were surrounded by lead from car exhaust, factories, paint, and even drinking water, often without realizing the damage it caused. By analyzing hair samples preserved across generations, scientists uncovered a striking record . ...

New research suggests that Epstein-Barr virus may actively provoke the immune system in people with multiple sclerosis. Scientists found large buildups of virus-targeting immune cells in the nervous systems of MS patients, far more than in their ...

New research using rhesus monkeys suggests that the brain's relationship with alcohol may begin forming long before a person ever takes a drink. Scientists found that exposure to alcohol before birth reshaped the brain's dopamine system, a key player ...

Scientists in Australia have uncovered a clever new way to fight some of the most dangerous drug-resistant bacteria by targeting a sugar that exists only on bacterial cells. By designing antibodies that recognize this unique sugar, researchers were . ...

Scientists have found that ancient Martian lakes could have survived for decades despite freezing air temperatures. Using a newly adapted climate model, researchers showed that thin, seasonal ice could trap heat and protect liquid water beneath. ...

A new imaging breakthrough combines ultrasound and light-based techniques to generate vivid 3D images that show both tissue structure and blood vessel activity. Developed by researchers at Caltech and USC, the system delivers detailed results quickly ...
