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 ...

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 ...

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 ...

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 ...

In a bid to better understand how cancer cells power their explosive growth and spread, scientists at Johns Hopkins Medicine say they have shed new light on the location and function of ...
