Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do ...

A single protein bolted to the inner membrane of a bacterial cell can shred a virus’s DNA before that genetic material ever ...

Inflammation, the movement of immune cells to an area of infection or injury, is important for tackling infections and restoring health. When the inflammatory process gets out of control, however, the ...

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 ...

Schematic of an active cell membrane. In a typical active biological process, active proteins (shown in a variety of colors) in a cell membrane (shown in blue) interact with various biological ...
