Researchers have engineered microbes that can't run away from home. Any refugees that do quickly die without protective proteins produced by their peers. Dubbed 'swarmbots' for their ability to survive in a crowd, the system could be used as a safeguard to stop genetically modified organisms from escaping into the surrounding environment. It could also reliably program colonies of bacteria to respond to changes in their surrounding environment.
