A team of scientists from the University of Antwerp (Belgium), Delft University of Technology (Netherlands) and the University of Hasselt (Belgium) have reported on bacteria that power themselves using electricity and can send electrical currents over long distances through highly conductive power lines. Centimeter-long bacteria from the seafloor contain a conductive fiber network that operates in a way comparable to the copper wiring that used to transport electricity. The highly conductive fibers enable a completely new interface between biology and electronics, providing a prospect for new materials and technology.
