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.

Memories of the horrific Virginia Tech tragedy came flooding back for many today, as shots were fired at the University of Central Arkansas.

Observations from NASA's Rossi X-ray Timing Explorer (RXTE) have revealed that the youngest known pulsing neutron star has thrown a temper tantrum. The collapsed star occasionally unleashes powerful bursts of X-rays, which are forcing astronomers to rethink the life cycle of neutron stars.

Four years ago, NASA's Stardust spacecraft chased down a comet and collected grains of dust blowing off its nucleus. When the spacecraft Comet Wild-2 returned, comet dust was shipped to scientists all over the world, including University of Minnesota physics professor Bob Pepin.

Using ESO's Very Large Telescope, an international team of astronomers [1] has discovered a stunning rare case of a triple merger of galaxies. This system, which astronomers have dubbed 'The Bird' - albeit it also bears resemblance with a cosmic Tinker Bell - is composed of two massive spiral galaxies and a third irregular galaxy.

Astronomers have found a new population of faint protogalaxies by taking the most sensitive spectroscopic survey ever of a time when the universe was only 15% of its present age. These objects are the probable building blocks of galaxies today, including our own Milky Way.

Breakthrough astrophysics research may have established the hitherto mysterious source of exceptionally high-energy cosmic ray emissions, according to recently published research that culminates a project developed by a scientist at the U.S. Department of Energy’s (DOE) Argonne National Laboratory.

NYU School of Social Work to be Named the Silver School of Social Work at NYU.

Over 600 participants from Schools of political studies in 15 European countries will gather in Strasbourg from 2 to 6 July for the second Summer University for Democracy, organised by the Council of Europe.

More first-generation college students cite parental encouragement as a key reason for attending college than their peers with college-educated parents, according to a new survey of freshman trends released by the Cooperative Institutional Research Program at UCLA.

Fresno Police Chief Jerry Dyer announced at 12:25 p.m. today the apprehension of the suspect in the shooting at an off-campus apartment complex.

Earlier today, NBC News headquarters in New York received correspondence believed to be from Cho Seung-Hui, the gunman responsible for the fatal shootings at Norris Hall. The correspondence includes multiple photographs, video, and writings.
