Large-scale cousin of elusive 'magnetic monopoles' found at NIST
Any child can tell you that a magnet has a "north" and a "south" pole, and that if you break it into two pieces, you invariably get two smaller magnets with two poles of their own. But scientists have spent the better part of the last eight decades trying to find, in essence, a magnet with only one pole. view more (2009-10-07)
Spallation Neutron Source first of its kind to reach megawatt power

New experiment could reveal make-up of the universe
The detectors will become part of the Advanced Gamma Tracking Array (AGATA) experiment, currently based in Italy, which aims to create a 'fingerprint' of the inside of the atomic nucleus to understand the structure of all matter in the Universe, including human beings and the stars. view more (2009-08-06)
On the path to metallic hydrogen
Hydrogen, the most common element in the universe, is normally an insulating gas, but at high pressures it may turn into a superconductor. view more (2009-08-04)
Spallation Neutron Source sees first target replacement
Having outlasted all expectations of its service life, the original mercury target of the Spallation Neutron Source (SNS), the Department of Energy (DOE) Office of Science's record-setting neutron science facility at Oak Ridge National Laboratory, is being replaced for the first time. view more (2009-07-28)
Ytterbium's Broken Symmetry
Ytterbium was discovered in 1878, but until it recently became useful in atomic clocks, the soft metal rarely made the news. Now ytterbium has a new claim to scientific fame. view more (2009-07-23)
