Google's latest "moonshot" project involves detecting cancer by swallowing a pill.
The pill is packed with tiny magnetic particles, which can travel through a patient's bloodstream, search for malignant cells and report their findings to a sensor device that you wear.
The project announced Tuesday is the latest effort by the Internet giant's X division, which tries to apply creative technology to solving big problems. The same division is also working on some of Google's other outlandish projects, like self-driving cars and contact lenses that can measure glucose in tears.
