US Recaptures Reign As Having World's Fastest Supercomputer
2012-06-18 09:06:53

It has been more than two years since the US lost the number one spot on the TOP500 list of the world´s fastest supercomputers to China, which then lost that spot to Japan´s K Computer. Now, after IBM unveiled its Sequoia BlueGene/Q System which manages a sustained 16.32 petaflops, the title is returning to the US, dropping Japan to second. The computer, built for the National Nuclear Security Administration (NNSA) by IBM, outpaces Japan´s K Computer by more than 5 petaflops...

Precise Measurement Of Radiation Damage Identified
2012-06-06 06:55:26

Lawrence Livermore National Laboratory researchers have for the first time simulated and quantified the early stages of radiation damage that will occur in a given material. "A full understanding of the early stages of the radiation damage process provides knowledge and tools to manipulate them to our advantage," said Alfredo Correa, a Lawrence Fellow from Lawrence Livermore National Laboratory in the Quantum Simulations Group. Nuclear radiation leads to highly energetic ions that can...

Simulations Show Nuclear Weapon Performance In Molecular Detail
2012-06-06 03:56:29

U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail, tools that are becoming critical for national defense because international treaties forbid the detonation of nuclear test weapons. The simulations must be operated on supercomputers containing thousands of processors, but doing so has posed reliability and accuracy problems, said Saurabh Bagchi, an associate professor in Purdue University's School of Electrical and Computer...

Atmospheric Warming Intensifies Earth’s Water Cycle
2012-05-22 04:29:42

Australian scientists from the Lawrence Livermore National Laboratory in California and the Commonwealth Scientific and Industrial Research Organization (CSIRO) report that in the last fifty years, salinity levels in the world´s oceans have shifted and that climate change is affecting global rainfall and evaporation cycles. According to the lead author of the study, Dr. Paul Durack, researchers looked at the correlations between salinity, rainfall, and evaporation in climate models...

For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second). Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma. Ultrafast phase...

The lot will be included in the 15th ICAP Ocean Tomo IP Auction on March 29, 2012, at Terranea...

Climatologists Predict More Extreme Summer Temperatures in 21st Century
2012-02-16 14:32:07

A new report published by an American non-profit research center says that extreme summer temperatures are becoming increasingly commonplace in the United States, a trend that they project will continue throughout the 21st century. Climatologist Phil Duffy led a group of researchers at the Lawrence Livermore National Laboratory (LLNL) in California in analyzing the results of various climate models examining the occurrence of extreme high temperatures in the summer months of June, July and...

High-Pressure Phase Changes Could Play Role In Exoplanet Formation
2012-02-12 05:37:38

Phase transitions in liquid magmas at the pressure and temperature levels that exist deep within Earth-like planets could play a role in the formation of new worlds, according to a new research put forth by experts at California's Lawrence Livermore National Laboratory (LLNL). According to a Friday UPI article, the process is similar to the way that graphite, when placed in high-pressure conditions, can transform into diamonds. In much the same way, the LLNL researchers assert that molten...

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...
