Microscopic 'clutch' puts flagellum in neutral
It has been long been known that bacteria swim by rotating their tail-like structure called the flagellum. The rotating motion of the flagellum is powered by a molecular engine located at the base of the flagellum. Just as engaging the clutch of a car connects its gear to its engine and delivers power to its wheels, engaging the molecular clutch of a bacterium connects its gear to its engine and delivers power to its flagellum.
