Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of ...

The axoneme of a mature flagellum in a sperm of Polytrichum juniperinum contains a double helix of two 500 Å ribbons, between the central fibers and the peripheral doublets. This double helix ...

Many species of swimming bacteria have a rotary structure called a "flagellum," consisting of more than twenty different kinds of proteins. By rotating their flagellar filaments and gaining propulsion ...

We analysed L. mexicana flagellum length, structure and biochemical changes, using electron microscopy and cell lines-expressing enhanced green fluorescent protein (eGFP) fusions of axonemal proteins, ...

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 ...

Bacteria are able to translocate by a variety of mechanisms, independently or in combination, utilizing flagella or filopodia to swim, by amoeboid movement, or by gliding, twitching, or swarming. They ...

When headed the wrong way, some bacteria turn by letting their propellers flop. The newly discovered turning mechanism explains how a marine bacterium can control its direction using only a single ...

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 ...

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 ...
