image: Carboxysomes, shown here in green, are enzymatic complexes that facilitate the carbon-fixing Calvin-Benson cycle in bacteria. These structures are found evenly spaced in the cytoplasm of the cyanobacterium Synechococcus elongatus PCC7942, which use this organization to ensure equal partitioning of these essential complexes during cell division. This image relates to an article that appeared in the March 5, 2010, issue of Science, published by AAAS. The study, by Dr. D.F. Savage at Harvard Medical School in Boston, Mass., and colleagues, was titled, "Spatially Ordered Dynamics of the Bacterial Carbon Fixation Machinery." view more
