In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an ...

When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ensure the signal reaches the correct effector without triggering pathways ...

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 ...

Researchers have discovered that damage to the cell membrane promotes cellular senescence, or cell aging. Our cells are surrounded by a fragile membrane that's only 5 nanometers thick, 1/20 of a soap ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has been out of reach. Subscribe to our newsletter for the latest sci-tech ...

But when the Johns Hopkins team examined cancer cells grown in the lab, they found that energy-generating enzymes gather and move as waves on the cell membrane, suggesting a more fine-tuned energy ...
