Today, two groups of scientists announced they've created modified E. coli strains that requires lab-made food in order to survive — so if any of these altered E. coli make it to the wild, they're toast.

Other kinds of containment exist for GMOs. One strategy is to disable their ability to make certain kinds of essential nutrients — but this strategy isn't foolproof, since...
