Falko sqDr. Paul Falkowski and his Rutgers colleagues have discovered two protein folds important for understanding the evolution of cellular metabolism. Evidence suggests that the processes responsible for facilitating the biological redox reactions shared by members of the "tree of life" may have first appeared billions of years ago during the Archean Eon. Falkowski's team provide clues to not only the ways these ancients cells may have operated, but also the origins of life itself. click here for paper
