Yale Scientists Discover That Light Accelerates Conductivity in Nature’s “Electric Grid”

There is a global web of tiny bacteria-generated nanowires in the soil and oceans that “breathe” by exhaling excess electrons, composing an intrinsic electrical grid for the natural world. In a new research study, Yale University scientists found that light is a surprising ally in fostering this electronic activity within biofilm bacteria. They discovered that exposing bacteria-produced nanowires to light yielded an up to a 100-fold increase in electrical conductivity.
