Researchers simulated nearly every molecule in a bacterial cell — and then watched the cell grow and reproduce.

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 ...

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 ...

Investigators have identified several steps in a cellular process responsible for triggering one of the body's important inflammatory responses. Their findings open up possibilities for modulating the ...

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 ...
