SAYS PHYSICIST, December 08
A University of Arizona physicist has shown that it should be possible to restrict electrons to two dimensions in space by placing conducting materials within strong magnetic fields. The fundamental discovery is important because it says that superconductivity is stable in this strongly magnetic environment. Stable superconductors are sought by energy, transportation, medical and computing industries.

PULSE: THE IMPACT OF EUROPEAN PULSAR SCIENCE ON MODERN PHYSICS, December 08
Pulsars are neutron stars that rotate quickly, up to 600 times per second. They are compact -- only 20 kilometres in diameter -- leftovers of supernova explosions. Nonetheless they have a mass 1.4 times that of our sun, and a very strong magnetic field. They emit beams of radiation from two regions above their magnetic poles, using a mechanism that is not completely understood.
