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 Bloomington and Harvard ...

The single flagellum of Trypanosoma brucei has been unveiled as a key player in determining cell polarity, division, size and shape. The flagellum, an appendage whose structure is conserved from ...

Scientists have studied a new target for antibiotics in the greatest detail yet – in the fight against antibiotic resistance. The ‘molecular machine’ flagellum is essential for bacteria to cause ...

Most bacteria have flagella; they are threadlike appendages extending from the surface of many microbes. They help move the organism around, a function called motility, in a rotating motion. Enabling ...

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 ...

THREE years before his death in 1805, English philosopher William Paley proposed a now-famous thought experiment. Imagine discovering a watch on the heath: how would you explain its intricate ...

A tiny but powerful engine that propels the bacterium Bacillus subtilis through liquids is disengaged from the corkscrew-like flagellum by a protein clutch, scientists have learned. Scientists have ...

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 ...
