A Toxic Glow In July, researchers at Emory University made tumors in rats glow by injecting the rodents with quantum dots, submicroscopic semiconductors that shine when light is beamed at them. The next step: making the dots glow in the infrared spectrum—those wavelengths are easier to see through body tissues than are visible light waves.
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.
