The Inner Workings of a Bacterial Black Box Caught on Time-Lapse Video

Cyanobacteria, found in just about every ecosystem on Earth, are one of the few bacteria that can create their own energy through photosynthesis and “fix” carbon – from carbon dioxide molecules – and convert it into fuel inside of miniscule compartments called carboxysomes. Using a pioneering visualization method, researchers from UC Berkeley and the Joint Genome Institute made what are, in effect, movies of this complex and vital cellular machinery being assembled inside living cells. They observed that bacteria build these internal compartments in a way never seen in plant, animal and other eukaryotic cells: from the inside out. More>
