E. coli's new diet? Scientists develop bacteria that 'eats CO2'

In a scientific breakthrough, researchers have engineered a new strain of bacteria that consumes carbon dioxide for energy instead of compounds like sugar or other organic molecules. Published in the journal Cell, the study effectively reprogrammed the E. coli bacterium's diet over generations. The scientists said that 'teaching a gut bacterium to do tricks that plants are renowned for was a real long shot,' but this may prove to be very healthy for the planet.
