A new study suggests some of these microbes are siphoning off massive amounts of carbon as it enters Earth, using it to fuel their own sunless ecosystems. Jennifer Glass, biogeochemist and associate professor in the School of Earth and Atmospheric Sciences, was not involved in the study, but calls it "a really big leap forward." Glass adds that this is one of the first papers to show how subterranean microbes can trap globally significant amounts of carbon.
