Simulated nanowires just half a DNA strand wide offer tantalizing clues to fulfilling the potential of LED lighting with efficient, natural-looking white light that can be dynamically "tuned" to mimic everything from sunlight to lamplight and moonlight. » Read More

Climate Change Affects Flooding in Okavango Delta

OkavangoDeltaCRDhp.jpg

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. » Read More

A New Mathematics for Experimental Science

ALScamera

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 Center for Applied Mathematics for Energy Research Applications (CAMERA) comes in. » Read More

Oakland 7th Graders Learn How Math Relates to Imaging

DANIoutreach

Seventh-grade students at Oakland’s Head-Royce School got a special math lesson from Berkeley Lab’s Daniela Ushizima. She connected their advanced linear algebra lessons to how images are processed and manipulated by computers, including popular apps many students use on their phones. » Read More

Simulations Shed Light on Pine Island Glacier’s Stability

PineIslandGlacier2013 Nov.10

The rapid retreat of Antarctica’s Pine Island Glacier has perhaps reached a point of no return, say researchers writing in Nature Climate Change. They used three different ice-flow models including BISICLES, which was developed by a collaboration that included Berkeley Lab computational scientists. » Read More

To Bridge LEDs’ Green Gap, Scientists Think Small…Really Small

April 4, 2014

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.

CRD’s John Shalf Discusses Big Data with White House Staff

March 31, 2014

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.

Simulations Shed Light on Pine Island Glacier’s Stability

February 28, 2014

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.
