“In the future, you could be eating cancer-detecting robots in much the same way you take your morning vitamins. Researchers at MIT have created a new responsive material that can change along with its environment, using living cells that act like basic computers. The technique uses genetically engineered bacteria—fine-tuned to respond to various stimuli—that can be 3D-printed into any shape.”
