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 ...

Some microbes can squeeze through tight spaces by wrapping themselves in their flagellum—the tail-like structure they use to ...

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 ...

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 ...

Patterns of chemical interactions are thought to create patterns in nature such as stripes and spots. This new study shows that the mathematical basis of these patterns also governs how sperm tail ...

How well bacteria move and sense their environment directly affects their success in surviving and spreading. About half of known bacteria species use a flagella to move — a rotating appendage that ...

To build the machinery that enables bacteria to swim the flagellum is assembled piece by piece, ending with the helix called flagellar filament, composed of six different subunits called flagellins.

IN May 1949, a series of photographs of ants of the species Formica rufa, Latr., were taken by Raymond Kleboe of Picture Post, in collaboration with me, and in many of these worker ants were shown.
