It's Friday, so let's get a new Science Friday video up. Science Friday

"Bubbles can do computations, says Stanford professor Manu Prakash. Just like electrons running through wires in your computer, Prakash and Neil Gershenfeld, of MIT, directed bubbles through tiny etched tubes and showed basic computations were possible. Because the presence of a bubble can influence the behavior of another bubble, Prakash was able to build "and," "or" and "not" gates. Bubbles are bigger and slower than electrons, but they can carry things--meaning you could create as you compute, Prakash says."
OK, it's Monday, not Friday, but last week's Science Friday video is too cool to skip. Without further ado... Science Friday

"Maxwell von Stein, a 22-year-old graduate of The Cooper Union, built bicycle that uses a flywheel to store energy. Instead of braking, Max can transfer energy from the wheel to the flywheel, which spins between the crossbars. The flywheel stores the kinetic energy until Max wants a boost, then he can transfer the energy back to the wheel using a shifter on the handlebars."
This isn't today's Science Friday video, but it's a recent Science Friday video that I missed, OK? You'll like it, anyway. Science Friday

"In 1968, the New Jersey Senate decreed the town of Franklin a geological wonder: "The Fluorescent Mineral Capital of the World." Over 350 different minerals have been found in the area, ninety of which glow brilliantly under ultraviolet light. There are two mineral museums devoted to fluorescing rocks, the region's unusual geology and its zinc mining history."
