Two rotors are better than one, and if our recent excitement over UPenn’s quadcopter is any indication, four rotors is better than two. Sometimes. Researchers at the ETH Zurich recognize that different tasks call for different aircraft, and with that in mind they’ve designed the Distributed Flight Array, a flying platform consisting of multiple small autonomous single rotor aircraft that can dock with one another to create a larger, more powerful aircraft.
A new diagnostic test developed by researchers at ETH Zurich can tell if a patient has Type I diabetes, but gone are the days of blood samples and lab work. The new nanotech sensor can tell instantly if a patient has diabetes or an associated complication called diabetic ketoacidosis by simply analyzing a sample of exhaled breath.
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.
