Under pressure: New device’s 1.6 billion atmospheres per second assists impact studies

July 11, 2019 -  
A new super-fast high-pressure device at DESY's PERA III X-ray light source allows scientists to simulate and study earthquakes and meteorite impacts more realistically in the lab. The new-generation dynamic diamond anvil cell (dDAC), developed by scientists from Lawrence Livermore National...

Co-Optima identifies six new blendstocks for improved fuel economy, vehicle performance

July 3, 2019 -  
Three years after embarking upon a rigorous evaluation of a pool of more than 400 candidates, researchers with the Co-Optimization of Fuels & Engines (Co-Optima) initiative have identified six blendstocks from two chemical families that exhibit the greatest potential to dramatically increase...

Did comet impacts jump-start life on Earth?

June 27, 2019 -  
Comets screaming through the atmosphere of early Earth at tens of thousands of miles per hour likely contained measurable amounts of protein-forming amino acids. Upon impact, these amino acids self-assembled into significantly larger nitrogen-containing aromatic structures that are likely...

Stellar reactions in a galaxy not so far, far away

July 1, 2019 -  
Few people over the course of history have had a hand in discovering an atomic element. Yet nuclear chemist Dawn Shaughnessy joined a team of scientists from Lawrence Livermore National Laboratory ( LLNL ) and Russia that discovered five elements from 1989 to 2010. Now she leads the Nuclear and...

High-powered laser diodes can reduce residual stress in metal 3D printed parts

June 25, 2019 -  
In 3D printing, residual stress can build up in parts during the printing process due to the expansion of heated material and contraction of cold material, generating forces that can distort the part and cause cracks that can weaken or tear a part to pieces, especially in metals. Researchers at...

Microbial growth and carbon uptake are driven mainly by nature, not nurture

June 20, 2019 -  
For soil microorganisms, how much of their life’s work is driven by evolution (nature) versus their current environmental (nurture)? As it turns out, the evolutionary history of soil microorganisms plays a larger role in growth rates and carbon uptake, according to a new study appearing in the June...

LLNL-led study finds any single hair from the human body can be used for identification

June 18, 2019 -  
Any single hair from anywhere on the human body can be used to identify a person. This conclusion is one of the key findings from a nearly year-long study by a team of researchers from Lawrence Livermore National Laboratory’s ( LLNL ) Forensic Science Center (FSC) and Michigan State University ...

Turning the switch on biofuels

June 17, 2019 -  
Plant cell walls contain a renewable, nearly limitless supply of sugar that can be used in the production of chemicals and biofuels. However, retrieving these sugars isn’t all that easy. Imidazolium ionic liquid (IIL) solvents are one of the best sources for extracting sugars from plants. But the...

LLNL, foundation seek to set up ALS consortium

June 14, 2019 -  
Lawrence Livermore National Laboratory ( LLNL ) and the Livermore Lab Foundation ( LLF ) are exploring the establishment of a consortium that would leverage the Lab’s computing capabilities to identify causal factors for amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease. Under a newly...
