Biologists have long treated cell membranes as passive barriers, thin skins that separate the chemistry of life from the chaos outside. A new line of research suggests they may be far more dynamic, ...

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical ...

Cellular membrane proteins play many important roles throughout the body, including transporting substances in and out of the cell, transmitting signals, speeding up reactions and helping neighboring ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...

The constant, energy-driven motion inside living cells may generate electricity in a way no one fully recognized before.

Cancer cells have softer membranes than healthy cells. New nanoparticles exploit this physical difference to fuse selectively ...

When the cell's recycling stations, the lysosomes, start leaking, it can become dangerous. Toxic waste risks spreading and ...

While our cells are performing some important, basic functions, they can generate compounds known as reactive oxygen species ...
