Take a Nano Pill and Call Google in the Morning?

Google is in the early stages of developing a nanoparticle-covered pill to detect cancer and other serious health problems such as heart disease, according to Andrew Conrad, head of the life sciences team at Google X, who revealed the project last week. The pill would work in tandem with a wearable magnetic device worn by the patient; the device would guide the pill to different parts of the body and collect data could reveal the person's potential for developing a variety of health problems.
