Early-life stress may physically alter how DNA is packaged in the brain, leaving stress-related genes primed to activate more easily years later. In mice, researchers were able to block this effect, preventing the heightened anxiety and stress ...

A low-carb diet may raise LDL cholesterol much more sharply in people who are genetically predisposed to high cholesterol, particularly when they consume lots of saturated fat. The findings could help explain why people following seemingly similar .. ...

Three forgotten Assyrian kings may have been hiding in plain sight for more than 2,700 years. By piecing together clues from tablets, inscriptions, and an ancient statue, researchers argue that these rulers were omitted from the famous Assyrian King ...

A neuroscientist is challenging the idea that the brain contains a central system that actually "makes" our decisions. What we experience as choosing may instead emerge from the continuous interaction of perception, movement, the body, and the world ...

Scientists may have solved the mystery of why Antarctica froze millions of years before the Arctic. Slow-moving waves deep inside Earth gradually lifted East Antarctica, building mountains and a high plateau where snow and ice could survive even in a ...

Older adults who received the Shingrix shingles vaccine were 24% less likely to be diagnosed with dementia over four years in a study of more than 500,000 people. Researchers estimate the difference could amount to roughly one dementia case prevented ...

Researchers have found a way to supercharge natural killer cells, powerful immune cells that can attack cancer, so they can penetrate solid tumors and keep fighting once inside. In mice, these specially prepared tissue-resident cells slowed the ...

A huge section of Greenland's Petermann Glacier has snapped off, forming an ice island about the size of Manhattan. Satellites watched cracks spread rapidly before the 76-square-kilometer slab finally broke free on August 4. It is the glacier's ...

Scientists have created a highly efficient catalyst that breaks down stubborn lignin from plant waste into useful chemicals under relatively mild conditions. By revealing exactly how the catalyst works at the atomic level, the discovery could help .. ...

A sweeping analysis of thousands of animal genomes suggests that chromosomes do not evolve randomly but instead follow a limited number of irreversible "evolutionary highways." These one-way genetic changes preserve clues to more than 600 million ...
