Maybe you’ve heard coffee or cola drinkers say they’re “addicted” to caffeine. But a passion for this stimulant doesn’t compare to actually needing caffeine to survive and reproduce. Researchers recently transformed a germ into a true caffeine fiend. And when they were through, this bacterium had to consume caffeine — or die.
Its designers say their new microbe could be used to clean up waters tainted by caffeine. It also could help researchers measure the amount of caffeine in liquids.
