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

Maintenance of cardiac rhythm and pain sensation require the flow of ions across the membranes of all cells. Ion channels, which facilitate this movement, are protein assemblies that penetrate the ...

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, ...
