Think of all the work on the Neoproterozoic Snowball Earth, the evolution of oxygenic photosynthesis on the Early Earth and its role in the transition from a methane - dominated to a CO2 - dominated greenhouse, Martian paleoclimate, the climate of Venus and Titan, the nature of the glacial - interglacial cycles, and so many more.

The cyanobacterium Acaryochloris marina is being studied as a model organism for alternative pigment signatures of oxygenic photosynthesis adapted, for example, to the light of red dwarf stars. (giss.nasa.gov)
The researchers are exploring how this protein functions at the crossroad of calcium - and redox - dependent reactions to promote efficient oxygenic photosynthesis. (sciencedaily.com)
