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.

Human-induced climate change reduces chance of flooding in Okavango Delta

March 27, 2014

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

March 17, 2014

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. Read More »

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. Read More »
