11-Apr-2014 Simulation solves mystery of how liquid-crystal thin films disintegrate
Approximately four decades ago, theoreticians believed that only one of two mechanisms could explain rupture of liquid-crystal thin films. They also believed that these two mechanisms could not coexist. But 10 years ago experiments showed that these two mechanisms in many cases do coexist, according to Trung Nguyen of Oak Ridge National Laboratory, who ran unprecedented large-scale molecular dynamics simulations on Titan, America's fastest supercomputer, to model the beginnings of ruptures in thin films.
3-Mar-2014 Particle beam cancer therapy: The promise and challenges
Advances in accelerators built for fundamental physics research have inspired improved cancer treatment facilities. But will one of the most promising -- a carbon ion treatment facility -- be built in the US? Participants at a symposium organized by Brookhaven Lab for the 2014 AAAS meeting explored the science and surrounding issues.
13-Mar-2013 Accelerating particles accelerates science -- with big benefits for society
Tackling the most challenging problems in accelerator science attracts the world's best and brightest to Brookhaven Lab. It's only natural that ideas and techniques born here take root in new research facilities around the world -- and spark a host of spin-off applications for industry, medicine, national security, and more.
17-Jul-2012 Special report: Graphics processing units speed results in extreme-scale supercomputers
Can scientists and engineers benefit from extreme-scale supercomputers that use application-code accelerators called GPUs (graphics processing units)? Comparing GPU accelerators with today's fastest central processing units (CPUs), early results from diverse areas of research show 1.5- to 3-fold speedups for most codes. That acceleration means increased realism of simulations and decreased time to results. A special report details these findings.
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.
15-Jun-2007 Brain 3D mapping to combat neurodegenerative disease
Wanda felt a jolt of frustration run through
her when her husband forgot to meet her at
the clubhouse after their round of golf. How many times had this happened lately? It was becoming an embarrassment.
22-Mar-2007 An ounce of prevention
When you think about it, Americans go to great
lengths to be healthy these days. This generation is far
more knowledgeable about the benefits of a healthy
lifestyle than generations past. In addition to paying
attention to diet and exercise, many regularly take
precautions to avoid illness and disease. Today, taking
vitamin supplements, eating foods rich in antioxidants and
applying sunscreen are almost as commonplace
as brushing teeth in the morning. After all, an
ounce of prevention is worth a pound of cure.

17-Nov-2006 ScalaBLAST solves problems in record time
Scientists are dedicated to making
discoveries that influence our world, but making these discoveries takes time. It took Albert Einstein 16 years to express his general theory of relativity. Benjamin Franklin was first introduced to electricity experiments on a trip to Boston in 1746, but his famous lightning rod experiment
didn't occur until six years later -- and he knocked himself unconscious more than once in the process.
16-Nov-2006 Sometimes smaller is better
A research team from the Pacific Northwest National Laboratory, Oregon Health and Science University, University of Minnesota and the University of Idaho is studying the ability of nanoscale iron particles to reduce carbon tetrachloride, a common groundwater contaminant.
23-Oct-2006 DOE/EPA release top fuel economy lists for 2007 models
The U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA) today released the 2007 Fuel Economy Guide to help consumers make well-informed choices when purchasing new vehicles.
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.
