Creating a 'genetic firewall' for GMOs

Synthetic amino acids may one day allow scientists to create "genetic firewalls" that prevent GMO crops or animals from escaping into the wild and causing environmental damage, according to Harvard and Yale researchers. On Wednesday, scientists announced that they had genetically engineered bacteria whose very survival depended on lab-formulated amino acids. By "locking in" this synthetic nutritional requirement, researchers said the bacteria would quickly die if they escaped their carefully controlled environment and entered the world at large. "I don't want to be alarmist or anything, but I think the point is that these organisms do spread," said...
