Nanocar Wins Top Science Award 175

Lucas123 writes "A researcher who built a car slightly larger than a strand of DNA won the Foresight Institute Feynman Prize for experimental nanotechnology. James Tour, a professor of chemistry at Rice Univ. built a car only 4 nanometers in width in order to demonstrate that nanovehicles could be controlled enough to deliver payloads to build larger objects, such as memory chips and, someday, even buildings, like a self-assembling machine. Tour and a team of postgraduate and postdoctoral researchers constructed a car with chassis, working suspension, wheels and a motor. 'You shine light on it and the motor spins in one direction and pushes the car like a paddle wheel on the surface,' Tour said. The team also built a truck that can carry a payload."

X-Rays Emitted From Ordinary Scotch Tape 190

Maximum Prophet writes "When I was in High School, I built an X-Ray machine that (probably) didn't produce any X-Rays. I used an old vacuum tube and high voltage. Little did I know that simple triboluminescence would have enough energy to do useful work." The catch: you'll need to peel your tape in a vacuum, and have the x-ray film at the ready.
