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 ...

Many drug and antibody discovery pathways focus on intricately folded cell membrane proteins: when molecules of a drug candidate bind to these proteins, like a key going into a lock, they trigger ...

The upper size limit on cell-penetrating drug molecules may be much higher than medicinal chemists had thought. A research team reports that molecules believed to be much too large to diffuse across ...

The membrane that encases a biological cell is not simply a barrier; it is chock full of proteins involved in all sorts of critical biological functions. To really understand what membrane proteins ...

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 ...

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 ...

The human body is a dynamic place. Blood pumps, spinal fluid flows, oxygen comes in and carbon dioxide goes out. Deeper still, charged molecules pass through cell walls, quietly keeping the body's ...

Proteins long known to be essential for hearing have been hiding a talent: they also act as gatekeepers that shuffle fatty molecules across cell membranes. When this newly discovered function goes ...
