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 ...
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 ...
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 ...
For the first half of the twentieth century, the sensory cilium, which is a non-motile projection that most mammalian cells possess, was thought to be a functionless vestigial structure. A series of ...
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 ...
Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology’s most intensively studied molecular machines. Bacteria move through ...
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 ...
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 ...
