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 US Department of Energy's Argonne National Laboratory.

Joe V. Michael, a senior chemist at Argonne National Laboratory, has been awarded the distinction of AAAS Fellow. Election as a Fellow is an honor bestowed upon members of the American Association for the Advancement of Science by their peers.

The Pierre Auger Collaboration announced that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth. Using the Pierre Auger Observatory in Argentina, the team of scientists found that the sources of the highest-energy particles are not distributed uniformly across the sky. Instead, the Auger results link the origins of these mysterious particles to the locations of nearby galaxies that have active nuclei in their centers.

Scientists may be one step closer to understanding the atomic forces that cause friction, thanks to a recently published study by researchers from the University of Pennsylvania, the University of Houston and the US Department of Energy's Argonne National Laboratory.

IBM and the US Department of Energy's Argonne National Laboratory announced completion of a contract for a 445-teraflops Blue Gene/P system for the Argonne Leadership Computing Facility. As the ALCF's second major acquisition, this enhancement increases the system capability by a factor of five to 556-teraflops. This additional capacity will accelerate the coming era of petascale computation in support of breakthrough science and engineering aimed at solving our nation's most challenging scientific problems.

SiCortex, the first company to engineer a Linux cluster from the silicon up, today announced that the first production model of an SC5832, its flagship 5.8 teraflop system, will be installed at the US Department of Energy's Argonne National Laboratory. The lab and its community of researchers will take advantage of the unique capabilities and energy efficiencies of the SC5832 to conduct research in a variety of areas, including astrophysics, climate modeling, oil and gas exploration, seismic research and biotechnology.

The U.S. Department of Energy's Argonne National Laboratory is working closely with Chinese scientists and policy makers toward the goal of creating a cleaner Beijing and developing sustainable technologies for the 2008 Olympic Games and beyond.
