A long-term study found that while a ketogenic diet prevented weight gain, it also triggered major metabolic problems. Mice developed fatty liver disease, abnormal blood fats, and an impaired ability to control blood sugar--especially after ...

Findings could create new opportunities to treat and study neurodegenerative diseasesScientists discovered that sugar metabolism plays a surprising role in whether injured neurons collapse or cling to life. By activating internal protective programs, ...

Quantum technology has reached a turning point, echoing the early days of modern computing. Researchers say functional quantum systems now exist, but scaling them into truly powerful machines will require major advances in engineering and ...

Bright white rocks spotted by NASA's Perseverance rover are rewriting what we thought we knew about ancient Mars. These aluminum-rich clays, called kaolinite, usually form on Earth only after millions of years of heavy rainfall in warm, humid ...

The Ediacara Biota are some of the strangest fossils ever found--soft-bodied organisms preserved in remarkable detail where preservation shouldn't be possible. Scientists now think their survival in sandstone came from unusual ancient seawater ...

Scientists have found compelling new evidence that humans, not glaciers, brought Stonehenge's bluestones to the site. Using advanced mineral analysis, researchers searched nearby river sediments for signs glaciers once passed through the area--and .. ...

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 ...
