These ‘movies’ of proteins in action are revealing the hidden biology of cells

Since the 1950s, scientists have had a pretty good idea of how muscles work. The protein at the centre of the action is myosin, a molecular motor that ratchets itself along rope-like strands of actin proteins — grasping, pulling, releasing and grasping again — to make muscle cells contract. The basics were first explained in … Read more
