Many organisms – ranging from single-cell protists to humans – rely on microscopic hair-like structures to perform a wide range of cell signaling and motility-related tasks. 1 Flagella, cilia and pili ...

We analysed L. mexicana flagellum length, structure and biochemical changes, using electron microscopy and cell lines-expressing enhanced green fluorescent protein (eGFP) fusions of axonemal proteins, ...

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 ...

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 axoneme of a mature flagellum in a sperm of Polytrichum juniperinum contains a double helix of two 500 Å ribbons, between the central fibers and the peripheral doublets. This double helix ...

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 ...

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 ...

Male infertility is a major issue worldwide and its causes remain unclear. Now, an international team of researchers led by ...

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 ...

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 ...
