In order to live and grow, plants and animals need the hydrogen (H) and oxygen (O) which compose water, as well as carbon (C), nitrogen (N) and […]

University of Alaska Fairbanks researcher Katey Walter Anthony led the study, which, for the first time, documents the widespread occurrence of these terrestrial sources of geologic methane […]
