Freshening up contaminated water

Aug. 28, 2019- 
Nitrate is a troublesome groundwater contaminant that is mainly caused by fertilizer runoff on farmlands. Many wells in agricultural regions exceed the EPA limit for nitrate in drinking water, and without an economical treatment option the water is unfit for potable use. But Lawrence Livermore National Laboratory (LLNL) and Stanford University researchers have developed a technology that can...

At an event held Monday at Lawrence Livermore National Laboratory, U.S. Secretary of Energy Rick Perry and Sandy Weill, founder of the Weill Family Foundation, signed a memorandum of understanding (MOU) to formally initiate a public-private partnership for artificial intelligence (AI), neurological disorders and related subjects. The partnership will apply DOE-fueled AI capabilities to...

Jupiter shows its true stripes

Aug. 27, 2019- 
There’s a reason why Jupiter’s stripes are only skin deep. It turns out that the planet’s zonal winds -- the alternating east-west jet streams seen in photographs as colorful stripes -- only descend to 3,000 kilometers in the atmosphere. Magnetic fields can make fluids that conduct electricity (like Jupiter’s atmosphere) behave more like honey than water. Deeper into the planet, where the...

Hackathoners put coding skills to the test

Aug. 22, 2019- 
College students are used to pulling all-nighters. For Lawrence Livermore National Laboratory summer intern Amar Saini, a recent graduate of the University of California, Merced, LLNL’s Summer Hackathon was a 24-hour, caffeine-fueled marathon of coding, diagramming and problem solving. Although Hackathon participants aren’t required to stay overnight and are strongly encouraged to get a good...

'Quantum annealer' shows promise in study

Aug. 21, 2019- 
An international team of researchers, including Lawrence Livermore National Laboratory (LLNL) physicist Arjun Gambhir, has developed a new algorithm for solving polynomial systems of equations using a type of quantum computer called a "quantum annealer." The team systematically examined how this method scales when facing increasingly difficult mathematical equations, with promising results....

NARAC celebrates 40 years of operations

Aug. 20, 2019- 
"What the Lab’s National Atmospheric Release Advisory Center (NARAC) does is it provides dispassionate science during fearful events." In one sentence, Jay Tilden summed up what NARAC has done for the nation for the past 40 years. Tilden is the National Nuclear Security Administration’s (NNSA) associate administrator for Counterterrorism and Counterproliferation. He joined NNSA...

NIF celebrates a decade of operations

Aug. 13, 2019- 
In the decade since Lawrence Livermore National Laboratory’s (LLNL) National Ignition Facility (NIF) began operations, NIF has routinely heated and compressed matter to some of the most extreme temperatures and pressures ever obtained on Earth – temperatures of 100 million degrees and pressures 100 billion times that of the Earth’s atmosphere.  See event photos. Funded by the Department of...

DOE/NNSA, Lab announce partnership with Cray to develop NNSA's first exascale supercomputer

Aug. 13, 2019- 
The Department of Energy (DOE), National Nuclear Security Administration (NNSA) and Lawrence Livermore National Laboratory (LLNL) today announced the signing of contracts with Cray Inc. to build the NNSA’s first exascale supercomputer, "El Capitan."

Nanowire arrays could improve solar cells

Aug. 8, 2019- 
Transparent electrodes are a critical component of solar cells and electronic displays. To collect electricity in a solar cell or inject electricity for a display, you need a conductive contact, like a metal, but you also need to be able to let light in (for solar cells) or out (for displays). Metal is opaque, so the current techniques use metal oxides, most often indium tin oxide — a near...

Physicist Maria Gatu Johnson wins APS award

Aug. 6, 2019- 
Nuclear physicist Maria Gatu Johnson, who plays a key role in inertial confinement fusion (ICF) and Discovery Science campaigns at the National Ignition Facility (NIF), was named winner of the Katherine E. Weimer Award recognizing outstanding plasma science research by a woman physicist in the early stages of her career. "I am honored and grateful that my efforts to do the best work I can...

Study reveals new structure of gold at extremes

July 30, 2019- 
Gold is an extremely important material for high-pressure experiments and is considered the "gold standard" for calculating pressure in static diamond anvil cell experiments. When compressed slowly at room temperature (on the order of seconds to minutes), gold prefers to be the face-centered cubic (fcc) structure at pressures up to three times the center of the Earth. However, researchers...
