Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has been out of reach. Until now, scientists could only measure membrane ...

Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

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 ...

Tiny particles made from the membranes of human immune cells could offer a promising new way to fight fungal infections that ...
