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.

+ - The Sky is Falling

Submitted by Chicken Little
Chicken Little (666) writes "The sky is falling... in about 29 years. FTA "Circle your calendar. April 13th, 2036 could be a really, really bad day on planet Earth. A group of astronauts and engineers warns that an asteroid may pass uncomfortably close to Earth that day. The chances it will actually hit are just one in 45,000, but even at those odds, the scientists warn, the United Nations should consider a response.""
