Simulations Reveal Unusual Death for Ancient Stars

September 29, 2014

Those primordial stars—between 55,000 and 56,000 times the mass of our Sun, or solar masses—may have died unusually. In death, these objects—among the Universe’s first-generation of stars—would have exploded as supernovae and burned completely, leaving no remnant black hole behind. Read More »

Pore Models Track Reactions in Underground Carbon Capture

September 25, 2014

Using tailor-made software running on top-tier supercomputers, a Lawrence Berkeley National Laboratory team is creating microscopic pore-scale simulations that complement or push beyond laboratory findings.  The models of microscopic underground pores could help scientists evaluate ways to store carbon dioxide produced by power plants, keeping it from contributing to global climate change.  The models could be a first, says David Trebotich, the project’s principal investigator. “I’m not… Read More »

SPOT Suite Transforms Beamline Science

August 18, 2014

Most synchrotron light sources have been operating on a manual grab-and-go data management model, but a recent data deluge is quickly making this practice implausible. So scientists from the Advanced Light Source (ALS), CRD and NERSC teamed up to create SPOT Suite, and it is already transforming the way scientists run their experiments at the ALS. Read More »
