Avoiding meat might slightly lower the odds of reaching 100 -- but only for frail, underweight seniors. In very old age, staying strong and maintaining muscle matters more than long-term disease prevention. Older adults who included fish, eggs, or .. ...

A shingles shot might do more than prevent a painful rash -- it could actually help slow down the aging process. In a large national study of more than 3,800 Americans age 70 and older, those who received the shingles vaccine showed slower biological ...

A sweeping new analysis of the evidence suggests that exercise therapy -- long promoted as a first-line treatment for osteoarthritis -- may offer only small and short-lived relief, and in some cases might be no better than doing nothing at all. After ...

Eating nothing but oatmeal for just two days might sound extreme, but it delivered a striking payoff in a new clinical trial. People with metabolic syndrome who followed a short, calorie-reduced oat-based plan saw their harmful LDL cholesterol drop . ...

Scientists have zeroed in on a critical weak spot behind a rare but devastating brain autoimmune disorder often known as "Brain on Fire." The disease strikes when the immune system attacks NMDA receptors--key molecules involved in memory and thinking ...

Earth's magnetic shield is shifting in dramatic ways. New data from ESA's Swarm satellites show that the South Atlantic Anomaly -- a vast weak spot in Earth's magnetic field -- has grown by nearly half the size of continental Europe since 2014. Even ...

Mars' frozen ice caps may be time capsules for ancient life. Lab experiments show that key building blocks of proteins can survive tens of millions of years in pure ice, even under relentless cosmic radiation. Ice mixed with Martian-like soil, ...

A gel-like sugar coating on immune cells has been found to play a starring role in psoriasis. Researchers discovered that immune cells shed this outer layer to help them exit the bloodstream and enter inflamed skin. This challenges the long-held idea ...

Quantum computers need special materials called topological superconductors--but they've been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly adjusting the mix of tellurium and selenium in ...

A lost cache of 250-million-year-old fossils from Australia has rewritten part of the story of life after Earth's worst mass extinction. Instead of a single marine amphibian species, researchers uncovered evidence of a surprisingly diverse community ...
