Organic Haze, Glaciations and Multiple Sulfur Isotopes in the Mid-Archean Era
Shawn D. Domagal-Goldman (NAI PSU team), J.F. Kasting (NAI PSU team), D. T. Johnson (NAI CIW team), and J. Farquhar (NAI CIW and UCLA teams) have just published an article Organic haze, glaciations and multiple sulfur isotopes in the Mid-Archean era in Earth and Planetary Science Letters. The team used sulfur isotope signatures within ancient sediments and a photochemical model of sulfur dioxide photolysis to interpret the evolution of...

Strategies for Evolutionary Success - Sulfolipids
Researchers from NAI’s University of Rhode Island Team and their colleagues have studied the use of phosphorus vs. sulfur in the membrane lipid sythesis pathways of organisms resident in the ocean’s subtropical gyres. Their data show that the dominant organism in the phytoplankton, a cyanobacterium, has evolved a “sulfur-for-phosphorus” strategy; producing a membrane lipid containing sulfate and sugar instead of phosphate. This adaptation may have been a major event in Earth’s early history when the relative availability of sulfate...
