Google is commonly known as a technologically advanced company, and rightfully so. Their newest development is a pill with the capability to detect cancerous cells in the body. The pill is compacted with magnetic nanoparticles that search the bloodstream for traces of cancer. When the particles have completed their search, they will notify  you through a device you can wear. This technology is still a prototype and will take a few years to perfect before being released to the public, but its technological advances will provide a new step towards eradicating the disease from humanity.
