I heard last week that the ability of bacteria to form pili that act as electrical wires is not limited to the species of geobacter in which it was first discovered (press release here).
This reminded me of a different kind of bacterial electricity which I described in a feature back in 2012, which is now freely accessible:
Surprises from the sea floor
Microbiologist Derek Lovley and colleaugues at UMass Amherst report finding electrically conducting pili or 'e-pili' in more bacteria species than just the original Geobacter discovery he made 30 years ago.
