Researchers find that disorder is key to nanotube mystery

So far, no one has managed to explain why, at the molecular level, a stable liquid would want to confine itself to such a small area. Now, using a novel method to calculate the dynamics of water molecules, Caltech researchers believe they have solved the mystery. It turns out that entropy, a measurement of disorder, has been the missing key.

Where electrons get stuck in traffic

The thinnest wire in the world, made from pure gold, is being examined by physicists from the universities of Wuerzburg and Kassel. Its exceptional electrical conductivity is causing quite a stir: the electrons do not move freely through the wire, but like cars in stop-and-go traffic.
