Researchers discovered an unusual property of a bacteria that can "breathe" in some metal and sulfur compounds and create materials that can improve electronics, energy storage, and medical devices. Specifically, the anaerobic Shewanella oneidensis bacterium can produce molybdenum disulfide, a material that can transfer electronics as well as graphene, explains the press release from Rensselaer Polytechnic Institute, whose team of engineers carried out the research.
