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

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 ...

Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial ...

Scientists at Georgetown University's Lombardi Comprehensive Cancer Center have uncovered a new dual function for a ...

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 ...

A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular debris.
