Light accelerates conductivity in nature’s ‘electric grid’

The natural world possesses its own intrinsic electrical grid composed of a global web of tiny bacteria-generated nanowires in the soil and oceans that ‘breathe’ by exhaling excess electrons. Researchers have now discovered that light is a surprising ally in fostering this electronic activity within biofilm bacteria. Exposing bacteria-produced nanowires to light, they found, yielded an up to a 100-fold increase in electrical conductivity.
