Energy News: Researchers found bacteria that can transform light into chemical energy -- a method of photosynthesis still not completely understood by science, but which could become an energy windfall if it's duplicatable by industry. The discovery happened at the famed Yellowstone National Park. The bacterium has "light-harvesting antennae known as chlorosomes, which contain about 250,000 chlorophylls each. No member of this phylum nor any aerobic microbe was known to make chlorosomes before this discovery. The team found that Cab. thermophilum makes two types of chlorophyll that allow these bacteria to thrive in microbial mats and to compete for light with cyanobacteria," they explained in a Penn State news release .
