The bacterial flagellum is a complex organelle that is required for the motility that is driven by an ion-powered rotary motor. The assembly of multiple flagellar organelles in a single cell is ...

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 ...

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 ...

Prokaryotic cells have evolved numerous machineries to swim through liquid or crawl over surfaces. Perhaps the most common of these are the well-studied bacterial flagella and the unrelated archaeal ...

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 ...

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 ...

Nature abounds with wonders — and the quest to explain them has driven some epic human advances. But scientific discoveries are often resisted when they contradict powerful religious traditions.

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 ...

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 ...
