Researchers at Harvard Medical School and Massachusetts General Hospital built a living laser partly to study interactions between electronic and biological systems, and partly out of sheer curiosity. The world’s first biological laser, made from a single living cell, could lead to better microscope imaging inside the body and even targeted light therapies, researchers say.

As someone who has broken the same pinky toe three times and fractured my fifth metatarsal once, I can immediately see the appeal of a rug that lights up when you step on it. (I will conveniently neglect to mention that all my breaks happened during the middle of the day.) Invented by two engineering students at London South Bank University, the rug uses electroluminescence to glow under the weight of a footfall.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
