It has been long been known that bacteria swim by rotating their tail-like structure called the flagellum. (See the swimming bacteria in the figure.) The rotating motion of the flagellum is powered by ...

SOME cilia and flagella beat in a complex three-dimensional manner, and, in addition, the angular velocity at the tip is greater than at the base. Presumably the bundle of fibrils which make up a ...

An underwater robot can delicately propel itself in any direction with its 12 flexible arms, inspired by the flagella of bacteria. Its creators claim it can carry out underwater inspections without ...

One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are ...

BLOOMINGTON, Ind. -- A tiny but powerful engine that propels the bacterium Bacillus subtilis through liquids is disengaged from the corkscrew-like flagellum by a protein clutch, Indiana University ...
