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 ...

The single flagellum of Trypanosoma brucei has been unveiled as a key player in determining cell polarity, division, size and shape. The flagellum, an appendage whose structure is conserved from ...

Researchers used biochemical techniques and electron microscopy to uncover the structure of the bacterial MotA protein, which forms part of the propeller motor (flagellum). Three-dimensional analysis ...

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 ...

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 ...

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.

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 ...
