Bacterial nanowires: Not what we thought they were
Los Angeles CA (SPX) Aug 21, 2014
For the past 10 years, scientists have been fascinated by a type of "electric bacteria" that shoots out long tendrils like electric wires, using them to power themselves and transfer electricity to a variety of solid surfaces. A team led by scientists at USC has turned the study of these bacterial nanowires on its head, discovering that the key features in question are not pili, as previously believed, but rather are extensions of the bacteria's outer membrane equipped with proteins that transfer ... read more
