What if wormholes were never cosmic tunnels at all? New research suggests Einstein and Rosen's famous "bridge" may actually reveal something even stranger: time itself could flow in two directions at once. Instead of connecting distant places in ...

Getting enough vitamin B12 to meet current health guidelines may not actually be enough to protect the aging brain. Researchers at UC San Francisco found that older adults with "normal" but lower levels of active B12 showed signs of slower thinking, ...

A surprisingly simple walking tweak may offer new hope for millions living with knee osteoarthritis. In a year-long clinical trial, researchers found that slightly changing the angle of a person's foot while walking reduced knee pain as effectively . ...

Researchers have discovered how to fine-tune a futuristic type of porous glass that can trap gases like CO2 and hydrogen. Inspired by centuries-old glassmaking techniques, the team added sodium and lithium compounds to make the material easier to ...

A hidden crater in South Korea may hold clues to one of the biggest turning points in Earth's history: the rise of oxygen. Scientists discovered fossil-like stromatolites -- layered structures built by ancient microbes -- inside the Hapcheon impact . ...

The world's oceans are rising at an accelerating pace, and scientists now say they can fully explain what's driving it. Warming seawater is the biggest factor, while melting glaciers and polar ice sheets are increasingly pouring more water into the . ...

Researchers have discovered that the GLP-1 hormone targeted by drugs like Wegovy is present in very low amounts inside the joints of arthritis patients. That finding suggests high-dose GLP-1 medications could potentially reach the joints and ...

Scientists are uncovering a surprising truth about aging cells: some may damage the body, while others help protect it. The discovery is fueling a new wave of precision anti-aging therapies aimed at removing only the harmful "zombie" cells without .. ...

Mysterious red auroras spotted over Japan were found reaching astonishingly high altitudes, even during space storms considered relatively mild. The discovery suggests hidden solar activity may be stronger than scientists realized -- with potential . ...

Astronomers using NASA's James Webb Space Telescope have uncovered a rare world unlike anything in our solar system -- a giant planet about the size of Saturn with surprisingly Earth-like temperatures and an atmosphere packed with methane. The planet ...
