Scientists find hidden brain damage behind dementia​

A University of New Mexico scientist is revealing what might be one of the most overlooked causes of dementia — damage in the brain’s tiny blood vessels. Dr. Elaine Bearer has created a new way to classify these changes, showing that many people diagnosed with Alzheimer’s also suffer from vascular damage that quietly destroys brain […]

It’s not just genes — parents can pass down longevity another way​

Scientists studying tiny roundworms have uncovered how the secrets of a long life can be passed from parents to their offspring — without changing DNA. The discovery shows that when certain cellular structures called lysosomes change in ways that promote longevity, those benefits can travel from body cells to reproductive cells. This information is carried [&he

Why ultra-processed foods aren’t the real villain behind overeating​

Researchers from Leeds found that overeating is driven more by what people believe about food than by its actual ingredients or level of processing. Foods perceived as fatty, sweet, or highly processed were more likely to trigger indulgence. Surprisingly, the “ultra-processed” label explained almost none of the difference in overeating behavior. The findings

Strong friendships may literally slow aging at the cellular level​

Scientists discovered that lifelong social support can slow biological aging. Using DNA-based “epigenetic clocks,” they found that people with richer, more sustained relationships showed younger biological profiles and lower inflammation. The effect wasn’t about single friendships but about consistent connections across decades.

Scientists just found cancer cells’ hidden power source​

When cancer cells are physically squeezed, they mount an instant, high-energy defense by rushing mitochondria to the cell nucleus, unleashing a surge of ATP that fuels DNA repair and survival. This newly discovered mechanism, visualized in real time with advanced microscopy, shows mitochondria acting like emergency first responders rather than static power plants
