Proceedings of the National Academy of Sciences of the United States of America, Vol. 117, No. 51 (December 22, 2020), pp. 32639-32647 (9 pages) Bacteria alternate between being free-swimming and ...

Sperm can modulate their energetics by regulating their flagellar waveform -- how the sperm oscillate their tails -- in order to adapt to varying fluid environments, potentially optimizing their ...

A: result of the motor resurrection experiments. B: distribution of the number of stators per flagellar motor (with bacteria swimming in free liquid environment) Flagellated bacteria are propelled by ...

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 ...
