MIT engineers have designed an ingestible, Jell-O-like pill that, upon reaching the stomach, quickly swells to the size of a ping-pong ball. The soft, squishy device -- big enough to stay in the stomach for an extended period of time -- could potentially track ulcers, cancers and other gastrointestinal conditions over the long term.
