A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

A study on worms led by researchers from Vanderbilt University School of Medicine in the US has uncovered a previously unknown adaptation to aging that actively remodels one of the largest and most ...

When injured, cells have well-regulated responses to promote healing. These include a long-studied self-destruction process that cleans up dead and damaged cells as well as a more recently identified ...

Ageing may not simply be the result of damage piling up over time. Scientists studying microscopic worms have discovered a striking structural change inside cells that could play a central role in how ...

As we age, our cells don’t just wear down—they reorganize. Researchers found that cells actively remodel a key structure called the endoplasmic reticulum, reducing protein-producing regions while ...

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of ...

While some people may be older in chronological age, their biological age might be much younger. FangXiaNuo/E+ via Getty Images You likely know someone who seems to age slowly, appearing years younger ...

A new study from WashU Medicine identifies a previously unknown way that cells purge waste in a process that helps them revert to a stem cell-like state to promote healing after injury. Here, three ...

Advances in public health and medicine have helped people live longer than ever before. However, those extra years are often affected by poor health ...

Plants and trees may seem pretty passive, but behind the scenes, their cells are working hard to put on a magic show. In this episode of Crash Course Botany, we’ll explore how the processes of ...
