The research was recently published by Physical Review B as a...

Guide star leads to sharper astronomical images

Dec. 4, 2018- 
The laser guide star revolutionized astronomy by revealing large swaths of the sky that had previously been unseen from Earth due to atmospheric distortions. Now astronomy is on the verge of another great leap forward. The Extremely Large Telescope, which is expected to see first light in 2024, will have a 39-meter-diameter primary mirror — more than three times the size of today’s largest...

Clark wins Davidson Award for Plasma Physics

Nov. 13, 2018- 
Daniel Clark, leader of NIF’s Capsule Modeling Working Group within LLNL’s Inertial Confinement Fusion (ICF) Program, has been named the winner of the 2018 Ronald C. Davidson Award for Plasma Physics. The annual award is presented by AIP (American Institute of Physics) Publishing, in collaboration with the American Physical Society (APS) Division of Plasma Physics, to recognize outstanding...

The future of carbon storage in forests

Nov. 8, 2018- 
Lawrence Livermore National Laboratory (LLNL) researchers and collaborators are looking to the future when it comes to carbon uptake in the forest ecosystem. Soil plays a major role in a healthy climate system. As the largest repository of carbon on land, soil can directly affect the concentration of carbon dioxide in the atmosphere.  When more nitrogen is concentrated in soil, the amount...

LLNL-Norway collaboration seeks improved predictive models for cancer outcomes

Nov. 6, 2018- 
A group of researchers from Lawrence Livermore National Laboratory recently visited the Cancer Registry of Norway (CRN) in Oslo to discuss the progress of ongoing collaborations between the two institutions aimed at applying big data analytics to predicting cancer risk and mortality.

Models show natural swings in the Earth's climate contribute to Arctic sea ice loss

Nov. 5, 2018- 
Arctic sea ice loss in the last 37 year is not due to humans alone. New research by a Lawrence Livermore National Laboratory (LLNL) scientist and collaborators show that Arctic sea ice loss is enhanced by natural climate fluctuations such as El Niños and La Niñas. With manmade greenhouse gases on top of the natural climate variability, the decrease in sea ice is even more severe than climate...

Don't rule out severe global climate change yet

Oct. 31, 2018- 
A key metric of global warming is the Earth’s "equilibrium climate sensitivity" (ECS), which represents the global surface warming that will accompany a doubling of atmospheric carbon dioxide. For nearly four decades, ECS was thought to be somewhere between 2.7 degrees Fahrenheit (F) and 8.1 degrees F, but a more precise estimate has eluded climate scientists. That was until Peter Cox and...
