but that they are spiral-shaped, and that they propel themselves by a gyrating, undulating movement of their bodies. Flagella or motor-organs, therefore, appear superfluous 3, 4.

Electron microscopy images reveal crucial structures and mechanisms within the molecular machinery that certain bacteria use ...

When speaking of motors, most people think of those powering vehicles and human machinery. However, biological motors have existed for millions of years in microorganisms.

Their study, published in Microbiological Research, reveals that bacteria can evolve by losing their flagella, the structures responsible for movement. The study was led by Prof. Wang Junfeng from ...

Likewise, for many years it was generally assumed that the entire phylum Nematoda, comprising roundworms, completely lacked cilia or flagella. Now it is known that they contain primary cilia ...
