Washington State University (WSU) scientists have captured bacteria that eat pollution and breathe out electricity. The bacteria reside in the Heart Lake Geyser Basin area in Yellowstone National Park where temperatures range from 110 to nearly 200 degrees Fahrenheit (43 to 93 Celsius). The scientists, led by WSU's Abdelrhman Mohamed, used special electrodes inserted at the edge of the hot springs to coax bacteria out. To do this in an extreme environment like hot springs, Mohamed invented a portable potentiostat. (A potentiostat is an electronic device capable of controlling the electrodes). After 32 days, the team successfully captured the bacteria in their natural environment. The researchers…
