Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes (LEDs), especially in the “green gap,” a portion of the spectrum where LED efficiency plunges, simulations at the U.S. Department of Energy’s National Energy Research Scientific Computing Center (NERSC) have shown.

Simulations Shed Light on Pine Island Glacier’s Stability
John Shalf, head of CRD’s Computer and Data Sciences Department, was one of four national lab representatives to meet with President Obama’s chief of staff and members of the Office of Science and Technology Policy (OSTP), Office of Management and Budget (OMB) and other agencies to discuss the intersection of big data architecture requirements and exascale challenges.
Researchers at the University of Cape Town, Berkeley Lab and the United Nations Development Programme have analyzed how human-induced climate change has affected recent flooding in an ecologically and geographically unique river basin in southern Africa—the Okavango River. After running a number of simulations, they found that greenhouse gas emissions have substantially reduced the chance of the floods in the region.
In the age of high-resolution detectors and international research collaborations, math has the potential to transform science and accelerate discovery. But this work will require state-of-the-art mathematics, carefully crafted in inventive new ways. That’s where the Department of Energy’s new Center for Applied Mathematics for Energy Research Applications (CAMERA) comes in.
The rapid retreat of Antarctica’s Pine Island Glacier has perhaps reached a point of no return, say three international modeling teams who ran a number of simulations to model the glacier’s behavior. To do this work, they relied on three different ice-flow models including BISICLES, which was developed by a collaboration that included Berkeley Lab computational scientists.
Seeing the Great Lights of Europe: A Study in Approaches to Synchrotron Data Management and AnalysisFebruary 21, 2014
Last month, David Brown and Craig Tull of the Computational Research Division (CRD) and Alex Hexemer of the Advanced Light Source went on a 10-day tour of Europe's light sources. Their stops included, Garching, Karlsruhe, Villigen, Hamburg and Oxford.
