If the photograph to the left looks like science fiction -- say, a slimy creature's brain cell hooked up to a man-made computer circuit -- sthere's a reason. It is, in fact, the neuron of a pond snail linked to a silicon chip.
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.
