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 ...

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 ...

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 ...

SOME cilia and flagella beat in a complex three-dimensional manner, and, in addition, the angular velocity at the tip is greater than at the base. Presumably the bundle of fibrils which make up a ...

One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are ...
