A new way to examine space, bugs and bones

Apr. 25, 2017 -  
A novel way to harness lasers and plasmas may give researchers new ways to explore outer space and to examine bugs, tumors and bones back on planet Earth. Lawrence Livermore National Laboratory (LLNL) physicist Felicie Albert led an international team pursuing this new regime in laser research,...

Research comes through with flying colors

Apr. 24, 2017 -  
Like a chameleon changing colors to blend into the environment, Lawrence Livermore researchers have created a technique to change the color of assembled nanoparticles with an electrical stimulant. The team used core/shell nanoparticles to improve color contrast and expand color schemes by using a...

Tweaking a molecule's structure can send it down a different path to crystallization

Apr. 21, 2017 -  
Silky chocolate, a more effective medical drug or solar panels all require the same thing: just the right crystals to make the material. Now scientists trying to understand the paths crystals take as they form have been able to influence that path by modifying the starting ingredient. The insights...

Study on impact of climate change on snowpack

Apr. 18, 2017 -  
An international team of scientists, including one from Lawrence Livermore National Laboratory (LLNL), has found that up to 20 percent loss in the annual maximum amount of water contained in the Western United States' mountain snowpack in the last three decades is due to human influence. Peak...

Pulsed ion beams reveal nonlinearity of radiation defect dynamics in silicon carbide

Apr. 13, 2017 -  
Materials scientists at Lawrence Livermore National Laboratory (LLNL) got a step closer to understanding defect interaction dynamics in silicon carbide. When an energetic particle, such as a neutron or an ion, impinges onto a material, the particle penetrates and creates displacements by ballistic...

Americans used more clean energy in 2016

Apr. 10, 2017 -  
Americans used more renewable energy in 2016 compared to the previous year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory . Overall, energy consumption was nearly flat. Each year, the Laboratory releases energy flow charts that illustrate the...

Experiments validate models predicting failure modes in miniaturized lightweight structures

Apr. 5, 2017 -  
Lawrence Livermore National Laboratory (LLNL) researchers have adapted theoretical models to predict the failure behavior of miniaturized 3D lattice structures and have used advanced characterization techniques to demonstrate that these failures exist. Specifically, experiments showed a transition...

Here comes the sun in first-time images

Apr. 3, 2017 -  
The first images from the Solar Ultraviolet Imager (SUVI) instrument aboard the National Oceanic and Atmospheric Administration's GOES-16 satellite capture a large coronal hole on the sun. The Geostationary Operational Environmental Satellites (GOES) are part of NOAA's space weather monitoring...

A new toolkit for rapid bacterial detection

Mar. 16, 2017 -  
Finding the right treatment plan for patients who have antibiotic-resistant infections is a costly and time-consuming effort. For doctors in rural areas or developing countries, there often is no source of electricity nearby or sterile lab conditions with microbiology specialists on hand. The...

Weisz selected for Hutcheon Fellowship

Mar. 13, 2017 -  
A Lawrence Livermore National Laboratory (LLNL) postdoc who was mentored by Lab scientist Ian Hutcheon has been named the first recipient of the Department of Homeland Security's (DHS) new fellowship that honors Hutcheon. David Weisz, who has worked at the Lab since August as a chemist in the...
