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 ...

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 ...

Flagella are tiny rotary motors that move bacteria. A research team led by Keiichi Namba, professor at Osaka University has used electron cryomicroscopy to show that a small difference of only several ...

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 ...

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 ...
