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

"It's a complicated story that has many interesting layers, but it's yet another example where curiosity driven research reveals the underlying mechanism of a very basic cellular process that is ...

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is ...

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 ...
