NERSCPowering Scientific Discovery Since 1974


Calming Plasma's Stormy Seas

Energy researchers continue to make headway in their quest to better understand what makes a fusion reaction “tick.” For decades, controlled nuclear fusion has held the promise of a safe, clean, sustainable energy source that could help wean the world from fossil fuels. But the challenges of harnessing the power of the sun in an Earth-based nuclear fusion reactor have been many, with much of… Read More »

To Bridge LEDs' Green Gap, Scientists Think 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 NERSC have shown. Read More »

Clocking the Early Universe's Expansion

April 17, 2014

By analyzing the light of distant quasars gathered by the Baryon Oscillation Spectroscopic Survey (BOSS), astronomers have made the most accurate calculation yet of the expansion rate of the young Universe. Their findings could help scientists discover the nature of dark energy, the mysterious, repulsive force that pervades our universe causing it to expand at an accelerating rate. Read More »

Taming Plasma Fusion Snakes

Controlled nuclear fusion has held the promise of a safe, clean, sustainable energy resource for decades. Now, with concerns over global climate change growing, the ability to produce a reliable carbon-free energy source has taken on new urgency. Read More »

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

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. Read More »
