Bacteria could soon be acting as microscopic "bio-batteries" thanks to a joint UK-US research effort.
The team of scientists has laid bare the power-generating mechanism used by well-known marine bacteria.
Before now it was not clear whether the bacteria generated an electrical charge themselves or used something else to do it.
Unpicking the process opens the door to using the bacteria as an in-situ robust power source.
