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

This is a diagram showing cholesterol's (red) predominance in the outer layer of the cell membrane. Cholesterol transport proteins (blue) can alter its distribution between the inner and outer layers.

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

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 ...
