“Take two of these and call me in the morning,” is a thing of the past. Now it is, “Swallow this Matrix-looking capsule and go sit over there by my laptop.” In all seriousness, some MIT researchers have designed a semipermeable capsule that can contain genetically engineered bacteria, that can throw markers when those came into contact with blood in the digestive tract. They are theorizing that this type of technology could be adapted to all sorts of detection techniques inside the human body.



MIT researchers have built an ingestible sensor equipped with genetically engineered bacteria that can diagnose bleeding in the stomach or other gastrointestinal problems.
