title: A New Era of Methanogenesis Research.
abstract: The reductive acetyl-CoA pathway coupled to methanogenesis is likely one of Earth's oldest metabolisms. Yet, until recently this metabolism had only been found in the kingdom Euryarchaeota. A study now suggests that distantly related Bathyarchaeota are also methanogens and that methane metabolism is more phylogenetically widespread than previously thought.
