Basic nanotechnology tools - the best routes to self-assembling 3-D shapes (w/video)

Researchers at Brown and Johns Hopkins universities have found optimal configurations for creating 3-D geometric shapes - like tiny, highly simplified geodesic domes that assemble by themselves. The Brown team developed the algorithmic tools, and the Johns Hopkins team tested selected configurations. The research may lead to advances from drug-delivery containers to 3-D sensors and electronic circuits.

Elusive ultrafine indoor air contaminants yield to NIST analysis

Researchers spent 75 days on the job carrying out some very important homework - measurements in a "typical dwelling" of the release, distribution and fate of particles almost as tiny as the diameter of a single DNA molecule. Particles ranging in size from 100 nanometers down to 2.5 nanometers that were emitted by gas and electric stoves, hair dryers, power tools and candles were tracked and analyzed.
