Animal cells are tiny, complex worlds with specialized parts working together to keep life going. From the flexible cell membrane to energy-making mitochondria and waste-clearing lysosomes, each ...

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 ...

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 ...

Electricity has always been central to how life works, from the firing of neurons to the beating of the heart, but new research suggests cells may be generating power in ways biologists had not ...

Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment ...
