Wonder conductors will spin up cooler computers - tech - 01 September 2010 - New Scientist: "In the past five years, physicists have uncovered a new kind of material that can keep electrons on the straight and narrow, eliminating collisions and slashing the amount of heat produced. Called topological insulators, these materials conduct electricity by harnessing a quantum-mechanical property of electrons called spin."
