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. Among these, many bacterial ...

Researchers explain the flagellar synchronization of swimming algae. The beating of flagella is one of the basic principles of movement in the cellular cosmos. However, up to now, scientists were ...

Flagellated bacteria are propelled by the rotation of helical flagellar filaments, each with a flagellar motor at its base. Taking Escherichia coli (E. coli) as an example, each cell has 3–7 flagella ...

This video presents a study in which, using cryo-electron microscopy, researchers determined the structure and mechanisms of a key component in the flagellar motor, which bacteria use to turn their ...

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.

Most motile bacteria move by the use of flagella. While the flagellar motor components have been identified, it remains unclear how they are assembled and activated. Researchers have now shown, ...
