Pill-sized camera gets to grips with your gut

Gut

Existing camera capsules designed to take images of the intestine cannot be controlled externally, so they simply drift through the gut along with everything else. “It’s like watching the view from a train window,” says the bot’s developer, Arianna Menciassi of the Sant’ Anna School of Advanced Studies in Pisa, Italy. “If you see something of interest, there’s no way to turn back and get a better look.”

Thanks to Steve for this.
