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

Biologists have long treated cell membranes as passive barriers, thin skins that separate the chemistry of life from the ...

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical energy through constant motion in their membranes, offering a fresh way to think ...

Even after decades of peering into cells, biologists are still finding surprises. In a twist, researchers at the University of Virginia and the National Institutes of Health uncovered a new organelle, ...

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 ...

Schematic of an active cell membrane. In a typical active biological process, active proteins (shown in a variety of colors) in a cell membrane (shown in blue) interact with various biological ...
