Electroactive microbes are so abundant, in fact, that researchers now suspect that they have a profound impact on the planet. The bioelectric currents may convert minerals from one form to another, for instance, fostering the growth of a diversity of other species. Some researchers have speculated that electroactive microbes may help regulate the chemistry of both the oceans and the atmosphere.
“To me, it’s a strong reminder of how ready we are to ignore things we cannot imagine,” Dr. Nielsen said.
Cool reminder of what we don’t know about the world around us. Sometimes I wonder if having a vast majority of the world’s knowledge accessible at our fingertips encourages a bias to believe that there is likely far more about the world that we don’t know our understand yet.
