A Cellular View of Earth History

Reporting by Helen Hill for the MIT Darwin Project

For the past several years, Rogier Braakman, a research scientist working in Penny Chisholm’s lab and collaborating with Mick Follows, has been studying how metabolism evolves in ocean microbes. In a new paper, he argues that intrinsic properties of cellular metabolism imposed central constraints on the historical trajectories of biospheric productivity and atmospheric oxygenation.  Continue reading

When Phytoplankton Go Hungry

by Helen Hill for MIT CBIOMES

The Redfield ratio, the atomic ratio of carbon, nitrogen, and phosphorus (C:N:P) in phytoplankton and deep ocean waters, has often been treated as a constant 106:16:1. A new paper involving several CBIOMES co-authors, among them two from the MIT Darwin Group, presents compelling evidence for what causes this ratio to change within phytoplankton. Continue reading
