Turning on a light makes tiny spheres self-assemble into flocks

Researchers at New York University engineered tiny spheres that self-assemble to form massive, ever-changing flocks. All it took was some chemistry, some physics, and the flip of a light switch. » 3/13/13 6:40am 3/13/13 6:40am

See self-assembling microstructures in action

We've heard a lot about self-assembling structures, but we rarely get to see a cool visual demonstration. This video shows several shapes and even complex, interlocking structures being assembled through "microfluidic channels." » 8/02/12 6:20am 8/02/12 6:20am
