For the first time, researchers have been able to show how a cell closes the door to free radicals—small oxygen molecules ...

RNA is usually portrayed as a molecule that works deep inside the cell, helping to turn genetic information into proteins.

When killer T cells of our immune system divide, they normally undergo asymmetric cell division (ACD): Each daughter cell ...

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet ...

Creating mini mitochondria factories helped recharge damaged cells in a dish, providing proof-of-concept work that could pave ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move ...

Testing in mice suggests that rejuvenating T cells could make vaccines and some cancer therapies more effective.

What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases. Until now, the genetic basis ...

A novel viral tool (FLEN) is designed, and used to monitor changes in the intrinsic and synaptic properties of engram cells quickly (3–6 hours) following encoding of a memory.

T his past year, we explored a lot of new cell biology research—from cancer to plants to microbes, and more! It’s hard to ...

The biological cycle of our existence seems relatively straightforward: we’re born, we live, we die. The end. But when you examine existence at the cellular level, things get a bit more interesting.
