Scientists have identified potentially cancer-causing chemicals hiding in many everyday foods, especially those exposed to high heat cooking methods like grilling, roasting, smoking, and frying. The compounds, known as PAHs, can form during cooking . ...

Scientists have uncovered a strange hidden structure formed during the creation of metallocenes, a class of sandwich-like molecules used in everything from catalysis to medicine. The newly characterized intermediate features a rare "double ring-slip, ...

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 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 . ...

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 ...

Eating too much junk food early in life may rewire the brain in ways that last into adulthood, even after switching to a healthier diet. Scientists found that high-fat, high-sugar diets changed feeding behavior and disrupted appetite-control regions ...

Scientists have uncovered alarming new evidence that a common insecticide may leave lasting marks on the developing brain before a child is even born. Researchers studying New York City children found that prenatal exposure to chlorpyrifos -- a ...
