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 Radiochemistry Group of the Physics and Life Sciences Directorate at LLNL and uses the National...

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 constituents of polymeric biomaterials. That is the conclusion of a new study by Lawrence Livermore...

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 Lawrence Livermore National Laboratory (LLNL) and the University of California, Davis are...

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 17 edition of the journal Nature Ecology & Evolution. "Our results suggest that, similar to...

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 sugars from IIL-treated biomass are inevitably contaminated with residual IILs that inhibit...
