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 ...
Researchers have discovered how bacteria break through spaces barely larger than themselves, by wrapping their flagella around their bodies and moving forward. Using a microfluidic device that mimics ...
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 ...
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 ...
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 ...
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 ...
Archaea use flagella known as archaella—distinct both in protein composition and structure from bacterial flagella—to drive cell motility, but the structural basis of this function is unknown. Here, ...
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 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 ...
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 ...
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 ...
