Jonathan Eisen blogs about a new photosynthetic bacterium found using metagenomic data. This report was published last week, to the dismay of Eisen's open-access soul, in Science. The researchers collected DNA from a hot spring in Yellowstone and discovered they had a new bacteriochlorophyll – synthesizing, phototrophic bacterium, now called Candidatus Chloracidobacterium thermophilum.
Catchy.
