A large French study tracking more than 100,000 people over a decade has found that higher consumption of certain food preservatives--commonly found in processed foods and drinks--is linked to a modestly higher cancer risk. While many preservatives . ...

Carbohydrates don't just fuel the body--they may also influence how the brain ages. A large long-term study found that diets high in fast-acting carbs that rapidly raise blood sugar were linked to a higher risk of dementia. People who ate more low .. ...

Physicists have discovered that hidden magnetic order plays a key role in the pseudogap, a puzzling state of matter that appears just before certain materials become superconductors. Using an ultra-cold quantum simulator, the team found that even ...

A new genetic study suggests that obesity and high blood pressure may play a direct role in causing dementia, not just increasing the risk. By analyzing data from large populations in Denmark and the U.K., researchers found strong evidence that ...

For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon atoms to slip through the metal. This slows ...

Our genome isn't as peaceful as it looks--some DNA elements are constantly trying to disrupt it. Scientists studying fruit flies discovered that key proteins protecting chromosome ends must evolve rapidly to counter these internal threats. When these ...

When materials become just one atom thick, melting no longer follows the familiar rules. Instead of jumping straight from solid to liquid, an unusual in-between state emerges, where atomic positions loosen like a liquid but still keep some solid-like ...

Astronomers may have finally cracked one of the universe's biggest mysteries: how black holes grew so enormous so fast after the Big Bang. New simulations show that early, chaotic galaxies created perfect conditions for small "baby" black holes to go ...

Webb's latest image of the Helix Nebula reveals a dramatic close-up of a dying star shedding its outer layers. The detailed view highlights glowing knots of gas shaped by fast-moving stellar winds colliding with older material. Changes in color trace ...

Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By splitting an entangled group of atoms into separate clouds, they were able to measure electromagnetic fields more precisely than . ...
