Personal Energy Orb Aruino project knows you haven't been exercising, cripples your computer

Spending too much time indoors? You need a Personal Energy Orb, a glowing Arduino powered ball that allows you to trade physical exertion for a tolerable mouse speed. Developed by two students at the University of Munich for a physical computing course, the PEO connects to a bike-mounted revolution counter to note how far a user rides, counting the total distance toward usable time on a computer. A fully "charged" green orb will allow a user to use their PC unhindered -- but a spent red orb will drag Windows' cursor sensitivity settings to its lowest. The idea, the project's creators say, is to annoy the user off of the computer and back on to their bike. It sure sounds aggravating to us. Check out the full homework assignment at the source link below, complete with goals, follies and Python scripts.

Scientists bend gamma rays, could neuter radioactive waste

Bending most light is easy; bending it in gamma ray form, however, has often been deemed impossible given how hard it is for electrons to react to the extreme frequencies. University of Munich scientist Dietrich Habs and his Institut Laue-Langevin teammate Michael Jentschel have proven that assumption wrong: an experiment in blasting a silicon prism has shown that gamma rays will refract just slightly through the right material. If a lens is made out of a large-atom substance like gold to bend the rays further, the researchers envision focused beams of energy that could either detect radioactive material or even make it inert by wiping off neutrons and protons. In theory, it could turn a nuclear power plant's waste harmless. A practical use of the technology is still some distance off -- but that it's even within sight at all just feels like a breakthrough.
