After beating a human at Go, the DeepMind AI's next challenge is preventing blindness

Diabetes can result in a common complication--known as diabetic retinopathy--that damages the back of the eye, known as the retina. The chronic disease can cause vision loss if left untreated. But, if caught early, patients can significantly reduce the risk of blindness. Google's DeepMind, which specializes in artificial intelligence, is partnering with Britain's National Health Service (NHS) to do just that. The NHS is Britain's publicly funded healthcare system--free to use, treating a million patients every 36 hours, and consisting of one of the largest workforces in the world.
