Genetically modified bacteria are widely used in the biotech industry to make products as diverse as yogurt and fine chemicals. But before these genetically modified organisms can be put to work outside the laboratory or factory—for example, in the human gut as probiotics—researchers need to develop reliable ways to keep them on a leash and kill them once their job is done.

A team led by Massachusetts Institute of Technology’s James J. . . .
