New theory unlocks the secret behind protein-membrane interactions

Trillions of cells -- all different shapes and sizes -- form a human body's structure. Surrounding each cell is a membrane, jointly acting as hostess and security -- welcoming certain information into the cell while making sure its components don't spill out into the body's void. Much is known about how the individual pieces of a cell work, but a significant understanding of how proteins interact with the cell membrane has remained a mystery until now, following a recent study.
