Ancient soils reveal clues to early life on Earth
New Nature paper out yesterday suggests using geochemistry that oxygen was in the atmosphere and cyanobacteria were in existence 3 billion years ago. No hard fossil evidence of the cyanobacteria exist...the line of thinking rests on the assumption that cyanos were the first oxygenic photosynthesizers. Anyways, cool paper.
A networking resource devoted to biological soil crusts and the researchers who study them. We will provide a means for international scientists to communicate, share their research, share important news and announcements, ask questions and find collaborators. We will also provide a space for informal writing on research, opinion, and ideas (now seeking posters!).
