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 ...

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 ...

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 ...

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 ...

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 ...

During this process, the cell selectively destroys certain areas of the endoplasmic reticulum. The discovery of ER phagia as part of the aging process indicates that in the future, the mechanism may ...

This video of a so-called HeLa cell dividing demonstrates how sensitive the cell division process is. While all is going well at the beginning of the video, as the clip nears its end you can see the ...
