Searching for primordial antimatter (10/31/2008)

Scientists are on the hunt for evidence of antimatter -- matter's arch nemesis -- left over from the very early Universe. New results using data from NASA's Chandra X-ray Observatory and Compton Gamma Ray Observatory suggest the search may have just become even more difficult. ...> Full Article

Spallation Neutron Source sends first neutrons to 'Big Bang' beam line (10/10/2008)

While most of the instruments at the Spallation Neutron Source are dedicated to materials and condensed-matter studies, the Fundamental Neutron Physics Beam Line will explore questions in nuclear physics. ...> Full Article

Physicist confines plasma components in a trap within a trap (5/7/2008)

Professor has taken a step toward simulating a type of matter found in the crusts of neutron stars, in the cores of gas giant planets, and in exotic plasmas thought to be present in the earliest universe. ...> Full Article

Latest Supercomputer Calculations Support the Six-Quark Theory (3/5/2008)

A new calculation, reported in the January 25, 2008 issue of Physical Review Letters, confirms the six-quark theory of particle-anti-particle asymmetry. This is the first complete calculation of this phenomenon to employ a highly accurate description of the quarks that adds a fifth dimension beyond those of space and time. ...> 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

Experiment Tightens Limits On Dark Matter: Physicists Revive Bubble Chamber Technology To Search For WIMPs (2/21/2008)

Scientists working on the COUPP experiment at the Department of Energy's Fermi National Accelerator Laboratory have announced a new development in the quest to observe dark matter. The Chicagoland Observatory for Underground Particle Physics experiment tightened constraints on the "spin-dependent" properties of WIMPS, weakly interacting massive particles that are candidates for dark matter. Their results, combined with the findings of other dark matter searches, contradict the claims for the observation of such particles by the Dark Matter experiment (DAMA) in Italy and further restrict the hunting ground for physicists to track their dark matter quarry. ...> Full Article

Researchers Examine Einstein's Theories (11/28/2007)

Einstein's self-proclaimed "biggest blunder" - his postulation of a cosmological constant (a force that opposes gravity and keeps the universe from collapsing) - may not be such a blunder after all, according to the research of an international team of scientists that includes two Texas A&M University researchers. ...> Full Article

Three first-ever isotopes created National Superconducting Cyclotron Laboratory (10/26/2007)

Researchers at Michigan State University's National Superconducting Cyclotron Laboratory (NSCL) have created three isotopes of magnesium and aluminum. The results not only stake out new territory on the nuclear landscape, but also suggest that variants of everyday elements might exist that are heavier than current scientific models predict. ...> Full Article
