Google Glass could help stop emerging public health threats around the world

The much-talked-about Google Glass -- the eyewear with computer capabilities -- could potentially save lives, especially in isolated or far-flung locations, say scientists. They are reporting development of a Google Glass app that takes a picture of a diagnostic test strip and sends the data to computers, which then rapidly beam back a diagnostic report to the user. The information also could help researchers track the spread of diseases around the world.
