Summer scholar reels in ‘STRIPED FISH’ for NIF

Oct. 22, 2019- 
In high school, Liz Grace thought physics was boring and instead considered studying psychology or music. But then a college professor inspired Grace to see the wonders of physics. Today, as a National Ignition Facility (NIF) & Photon Science Summer Scholar, she’s helping to design and build a diagnostic instrument that could become a revolutionary measurement tool for NIF’s Advanced...

Volcanic ash sparks new discovery

Oct. 21, 2019- 
Fort Lauderdale, Fla.— Imagine you’re getting ready to fly to your favorite vacation destination when suddenly a volcano erupts, sending massive amounts of ash into the atmosphere, and forcing the cancellation of your flight. That’s exactly what happened in April 2010 when Eyjafjallajokull, a volcano in Iceland, erupted and disrupted air travel in Europe for six days. Lawrence Livermore...

Unexamined lunar rocks indicate early bombardment

Oct. 16, 2019- 
A team of Lawrence Livermore National Laboratory (LLNL) scientists has challenged the long-standing theory that the moon experienced a period of intense meteorite bombardment about 3.8 billion years ago, when the first forms of life appeared on Earth.  This theory is known as the Late Heavy Bombardment and is thought to have resulted from disturbance of the asteroid belt due to the outward...

Researchers jump into DOE ‘shark tank’

Oct. 11, 2019- 
Researchers from a dozen Department of Energy (DOE) national labs recently converged on Northern California to compete in their own version of the popular “Shark Tank” television program.  Although Mr. Wonderful, Barbara Corcoran and Mark Cuban weren’t in attendance, the competition still boasted five judges who are highly successful entrepreneurs and angel investors in the Bay Area and...

LLNL team studies link between residual stress and mechanical properties of 3D-printed stainless steel

Oct. 8, 2019- 
The buildup of microscopic residual stresses that occur during the process of 3D printing metal parts can lead to deformation and even cracking in the part, complicating the printing process and resulting in defects that cause damage and part failure. To develop a strategy for mitigating these tiny stresses, Lawrence Livermore National Laboratory (LLNL) researchers have combined synchrotron...

FedTech helps accelerate technology transfer

Oct. 4, 2019- 
Two Lawrence Livermore National Laboratory (LLNL) computer scientists with promising technologies have taken part in a national organization’s commercialization program that pairs researchers with entrepreneurs. The two LLNL researchers, Timo Bremer and Jacqueline Peila, each worked for 12 weeks with teams of entrepreneurs, comprised of former CEO’s, executives, graduates and students with...

Lab team reports breakthrough in ultrafast, high-resolution nanoscale 3D printing

Oct. 3, 2019- 
While 3D printing at the nanoscale — producing intricate features orders of magnitude smaller than the width of a human hair — has significant potential in industry and commercial applications, wide adoption has been impractical because of the slow speed and low throughput of the most widely used nanoprinting technique, two-photon lithography (TPL). But in the latest of Science, posted...

Annual Expanding Your Horizons conference inspires girls to ‘follow your curiosity’

Oct. 3, 2019- 
The San Joaquin Expanding Your Horizons (SJEYH) conference for girls celebrated its 27th year with the theme, “Follow Your Curiosity.” Held in late September, approximately 500 girls came to the University of the Pacific Campus in Stockton to learn more about science, technology, engineering and mathematics (STEM). SJEYH, now affiliated with Techbridge Girls, is co-sponsored by Lawrence...

Six Lawrence Livermore researchers named 2019 fellows of the American Physical Society

Oct. 2, 2019- 
Six Lawrence Livermore National Laboratory (LLNL) scientists have been selected as 2019 fellows of the American Physical Society (APS). The new fellows represent a selection of physics expertise, ranging from computational physics and shock compression of condensed matter to instrument and measurement science. APS fellowships are awarded after extensive review and are considered a distinct...

Lab's space program is on the rise

Oct. 1, 2019- 
Nascent security challenges, novel scientific discoveries and new technology development opportunities are all part of outer space and in the focus of the Lawrence Livermore National Laboratory's (LLNL) Space Science and Security Program (SSSP). The national security community now refers to space as a “warfighting domain.” As such, it is both integral to the U.S. defense posture and...

New class of metal materials is its strong suit

Sept. 30, 2019- 
In a perfect world, engineers would like metals to be strong and electrically conducive without any defects. But no metal is perfect. It loses strength due to synthetic defects, causing a softening of the material. Lawrence Livermore National Laboratory (LLNL) scientists and collaborators have created a new class of metal material that keeps its strength and electroconductivity by...

New 3D-printed lattice designs defy conventional wisdom on metamaterials

Sept. 27, 2019- 
Lawrence Livermore National Laboratory (LLNL) researchers have designed a new class of 3D-printed lattice structures that combine lightweight and high stiffness, despite breaking a rule previously thought to be required to exhibit such properties. One of the new structures additionally displays perfectly uniform response to forces in all directions. As described in a paper published today by...

Use of nanopores could lead to cleaner water

Sept. 26, 2019- 
Not all nanopores are created equal. For starters, their diameters vary between 1 and 10 nanometers (nm). The smallest of these nanopores, called Single Digit Nanopores (SDNs), have diameters of less than 10 nm and only recently have been used in experiments for precision transport measurements. A team of Lawrence Livermore National Laboratory (LLNL) scientists and colleagues from seven...

Climate ensembles help to identify detection time of human-caused climate signals

Sept. 24, 2019- 
By comparing observations to large ensembles of climate model simulations, scientists can now better isolate when human-caused climate change was first identifiable in observations. Large Initial Condition Ensembles (LEs) are simulations of climate change performed with a single climate model. An LE typically has between 30 and 100 individual “members” in order to probe the range of natural...
