Robots are coming soon to a bowel near you! Italian scientists are working hard to bring a swallowable colon-crawling robot to your guts to help scan for colon cancer. The so-called spider-pill looks a lot like something from a sci-fi flick. Other similar robots have been developed, but this is the first that can be controlled by doctors wirelessly to hunt in all your bodily nooks and crannies. Not only will this make colonoscopies a heck of a lot more pleasant, but once the exam is over, the robot gets flushed away along with, uh, everything else. {BBC via Discover blogs}
