A microscopic speck of green algae can trot like a horse. Or gallop. Biophysicist Kirsty Wan compares the gaits of creatures large and small. Moving diagonally opposite limbs, or flagella in this case ...

New studies from Arizona State University reveal surprising ways bacteria can move without their flagella—the slender, whip-like propellers that usually drive them forward. Movement lets bacteria form ...

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 ...

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 beating of flagella is one of the basic principles of movement in the cellular cosmos. However, up to now, scientists were unsure as to how the movements of several of these small cellular ...

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 ...

A form of algae, called Chlamydomonas reinhardtii, has a very complicated way of swimming. A new study published in Nature magazine explains how individual algae cells can control their motion using ...

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 ...
