Right now, doctors only have a couple of choices when it comes to looking into the human body. Trying to discover a person's ailment in their intestines is tough, as it usually means that an endoscopy has to happen. Inputting a camera, connected to a long cable, down someone's throat isn't always what a patient is looking forward to, and the alternative isn't any better. And while capsules with cameras in them exist today, it's hard for doctors to see what's happening inside, as the movement is controlled by the person's innards. But, doctor's from Germany are looking to change that with a new remote-controlled capsule that can be swallowed.
