sciencedaily.com – Some of the tiniest diamonds in the universe -- bits of crystalline carbon hundreds of thousands of times smaller than a grain of sand -- have been detected swirling around three infant star systems in the Milky Way. These microscopic gemstones are neither rare nor precious; they are, however, exciting for astronomers who identified them as the source of a mysterious cosmic microwave 'glow' emanating from several protoplanetary disks in our galaxy.

digitaltrends.com – Bionic prostheses have evolved by leaps and bounds. One thing that most of them can't do, however, is let their wearers feel pain. That's changing thanks to researchers at Johns Hopkins University -- and, despite what you might think, that could turn out to be a positive step forward.
