Bacteria seen swimming the electron shuffle

Researchers have captured the bacterium Shewanella's behavior on film

New videos have caught bacteria in the act of a completely new behavior. A study appearing in the Dec. 14 Proceedings of the National Academy of Sciences finds that Shewanella cells briefly touch an electron-accepting surface, lift off and swim furiously, and then return to the metal surface.

The researchers call this flighty new behavior electrokinesis, and think it may be a way for bacteria to dump built-up electrons before taking off in search of food, much like a whale surfacing for a ...
