Water world

Three Washington University in St. Louis scientists studied the great granddaddy of all photosynthetic organisms — a strain of cyanobacteria — to develop the first experimental map of that organism’s water world.

Scientists stitch up photosynthetic megacomplex

In Science, scientists at Washington University in St. Louis report on a new technique that allowed them to extract a photosynthetic megacomplex consisting of a light antenna and two reaction centers from the membrane of a cyanobacterium. This is the first time an entire complex has been isolated and studied as a functioning whole.
