Ever since scientists discovered that certain microbes can get their energy from electrical charges, researchers have wondered how they do it. Bacteria don't have mouths, so they need another way to bring their fuel into their bodies. New research from Washington University in St. Louis reveals how one such bacteria pulls in electrons straight from an electrode source. The work from the laboratory of Arpita Bose, assistant professor of biology in Arts & Sciences, was published Nov. 5 in the scientific journal mBio. "The molecular underpinning of this process has been difficult to unravel until our work," Bose said. "This...
