9-Nov-2011 Researchers show how proteins help DNA replicate past a damaged site
A multi-institutional research team led by Ivaylo Ivanov of Georgia State University has employed the Jaguar XT4 supercomputer at Oak Ridge National Laboratory and X-rays a billion times brighter than the sun, produced at Lawrence Berkeley National Laboratory, to illuminate how DNA replication continues past a damaged site so a lesion can be repaired later. The results appear in the Oct. 17, 2011, online issue of Proceedings of the National Academy of Sciences.
1-Jun-2011 Chemistry and materials simulations speed clean energy production and storage
Catalysts are just one area of investigation for a multi-institutional team whose 70 publications in 3 years detail prodigious scientific output from the world's fastest chemistry simulations.
"Our long-term goal is enabling the design of new generations of clean and sustainable technologies to produce, transmit, and store energy," said team leader Robert Harrison, a computational chemist at Oak Ridge National Laboratory.
26-Jan-2011 Neutrons 'go viral' at ORNL
A research team from ORNL and North Carolina State University is using small angle neutron scattering to study how viruses change their structure when they move between different host species. Understanding how a virus reorganizes itself when it goes from a mosquito to a human is critical for the development of medicines that can block the spread of viruses.
29-Nov-2010 Jaguar pounces on child predators
To accelerate the acquisition of information needed to arrest child predators, law enforcement officers have teamed with data analytics experts at Oak Ridge National Laboratory for a project that will use Jaguar, one of the world's fastest supercomputers, to speedily analyze the activities on file-sharing networks that pinpoint porn producers.
19-Nov-2010 Supercomputers assist cleanup of decades-old nuclear waste
A research team led by Peter C. Lichtner of Los Alamos National Laboratory is using the Oak Ridge Leadership Computing Facility's Jaguar supercomputer, located at Oak Ridge National Laboratory, to build a 3-D model of an underground uranium waste plume at the Hanford Site's 300 Area. A better understanding of the underground migration properties of uranium, which has infiltrated the Columbia River, may aid stakeholders in weighing options for contaminant remediation.
27-Aug-2008 Hope for those with Parkinson's
A Department of Energy program that opens some of the world's most powerful computers to researchers around the globe has generated a promising lead for a Parkinson's disease treatment.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
