Supercomputer Confirms Standard Model Theory Of The Universe, Deepens Puzzle (3/7/2008)

Scientists have used a supercomputer to shed new light on one of the most important theories of physics, the Standard Model, which encapsulates understanding of all the material that makes up the universe. This 30-year-old theory explains all the known elementary particles and three of the four forces acting upon them - however, it excludes the force of gravity, which is its shortcoming. ...> Full Article

'Two-Faced' Particles Act Like Tiny Submarines in Study (2/29/2008)

For the first time, researchers at North Carolina State University have demonstrated that microscopic "two-faced" spheres whose halves are physically or chemically different - so-called Janus particles - will move like stealthy submarines when an alternating electrical field is applied to liquid surrounding the particles. ...> Full Article

Physicists compete against, collaborate with each other in search for dark matter (2/28/2008)

A race is on in Case Western Reserve University's physics department and around the world to be the first research group to capture signals from WIMPs (weakly interactive massive particles)-the substance that comprises dark matter. ...> Full Article

Researchers Announce First Observation of 'Persistent Flow' in a Gas (12/5/2007)

Using laser light to stir an ultracold gas of atoms, researchers have demonstrated the first 'persistent' current in an ultracold atomic gas -a frictionless flow of particles. This relatively long-lived flow, a hallmark of a special property known as 'superfluidity,' might help bring to the surface some deep physics insights, and enable super-sensitive rotation sensors that could someday make navigation more precise. ...> Full Article
