Human cells contain billions of molecules. To prevent complete chaos, these molecules and the reactions between them are ...

Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them ...

Epithelial cells form the body's frontline barriers, helping keep microbes, toxins and other harmful substances out. Yet these protective cells are constantly exposed to threats, including microbial ...

In a bid to better understand how cancer cells power their explosive growth and spread, scientists at Johns Hopkins Medicine say they have shed new light on the location and function of ...

A mitochondria-anchored synthetic organelle captured up to 90% of expressed gene transcripts in human cells and preserved ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...
