'Twisted' laser light experiments offer new insights into plasma physics
Electromagnetic vortices occur naturally throughout the universe and have recently been observed in association with black holes. Over the last decade, scientists have sought methods to investigate how extremely strong electromagnetic vortices interact with matter, specifically plasma, in a laboratory setting. Plasma, known as the “fourth state of matter,” makes up nearly…
2022 Gulbenkian Prize for Humanity jointly awarded to the IPCC
The United Nations (UN) Intergovernmental Panel on Climate Change (IPCC) was jointly awarded the Gulbenkian Prize for Humanity, alongside the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). The prize jury distinguished the two intergovernmental organizations for their role in developing scientific knowledge, alerting society and…
Two LLNL scientists selected as 2022 APS fellows
Two Lawrence Livermore National Laboratory (LLNL) scientists have been selected as 2022 fellows of the American Physical Society (APS). Physicists Andrea (Annie) Kritcher and Ronnie Shepherd were both selected by the APS Division of Plasma Physics. APS fellowships are awarded after extensive review and are considered a distinct honor because the evaluation process,…
New method sheds light on solid-state battery fabrication
Safe, long-cycle-life batteries with high energy density are greatly needed with the rapid growth of electric devices and vehicles and grid energy storage demands. Lawrence Livermore National Laboratory (LLNL) scientists have devised a method for the fabrication of all-solid-state lithium metal batteries, which have been recognized as the future choice of safe and high…
Breaking up is easy to do with copper-titanium catalysts
Producing fragrances and flavorings and converting chemicals derived from biomass could get a boost from a new technique to break up hydrogen in nanoporous copper-titanium catalysts. The dissociation (breaking up) of hydrogen bonds is an essential elementary step in catalytic hydrogenation (a chemical reaction between molecular hydrogen [H2] and another compound or element…
Kraus honored for inaugural American Physical Society award
Lawrence Livermore National Laboratory (LLNL) research scientist Richard Kraus is the recipient of the inaugural American Physical Society’s 2023 Neil Ashcroft Early Career Award for Studies of Matter at Extreme High Pressure Conditions. Kraus is recognized for his outstanding theoretical or experimental contributions by an early-career scientist to studies of matter at…
PLS postdocs to compete in the 2022 Bay Area Research Slam
On September 20, LLNL hosted its annual Postdoc Research Slam. This Lab-wide competition encourages postdocs to showcase their research in a three-minute presentation that answers the question, “Why is my research important?” The event gives postdocs the opportunity to improve their communication and speaking skills and challenges them to articulate their research in an…
Meet Training Specialist Bryni Soto
Brytni Soto joined LLNL in 2009 as a recruiting intern for a contract company. Today, she serves as the Training Specialist for Physical and Life Sciences – a role that she describes as being in direct alignment with her passion to support people in their pursuit of career growth.
Former Lab physicist earns Nobel Prize in Physics
John Clauser, an experimental physicist who spent a decade at Lawrence Livermore National Laboratory (LLNL), has been awarded the 2022 Nobel Prize in Physics, along with French scientist Alain Aspect and Austrian scientist Anton Zeilinger. The Nobel Committee, made up of members from the Royal Swedish Academy of Sciences, cited the trio for “experiments with entangled…
Earth System Grid Federation launches effort to upgrade global climate data system
The Earth System Grid Federation (ESGF), an international multi-institutional initiative that gathers and distributes data for top-tier computer simulations of the Earth’s climate, is preparing a series of upgrades that will make using the data easier and faster while improving how the information is curated. A new project called ESGF2, encapsulates the primary U.S…
Sheltering Science Saves Lives
Lawrence Livermore researchers have worked for more than a decade to provide insights for a multifaceted emergency response, and in the process, they have advanced the science of sheltering and developed computer models to identify potentially life-saving strategies.
Small Things Considered
Of the four forces, the weak nuclear force is the least understood and most difficult to detect. A Lawrence Livermore team headed by physicist Nick Scielzo partnered with scientists from Argonne National Laboratory, Louisiana State University, and other universities to better characterize the weak force’s foundations. Thanks to significant advances in experimental design…
Joining the Fight to Cure Neurodegenerative Disease
The Laboratory’s cutting-edge capabilities and expertise offer new tools to study ALS disease mechanisms and fuel hope for a cure.
Meet experimental scientist Gaby Davila Ordonez
Gaby Davila Ordonez has always had a knack in learning new things, contributing to make a difference and helping others succeed. Originally from Venezuela, Davila Ordonez, grew up with three sisters in a family who cultivated coffee in a small town in the state of Mérida called La Azulita.
It’s a metal, not a gas: flerovium chemical properties unveiled
It could be called better understanding through chemistry. An international research team including Lawrence Livermore National Laboratory (LLNL) scientists has succeeded in gaining new insights into the chemical properties of the superheavy element flerovium — element 114. The measurements, taken at the at the accelerator facilities of the GSI Helmholtzzentrum für…
The people of stockpile stewardship are the key to LLNL’s success
The last nuclear test, code-named Divider, took place 30 years ago, on Sept. 23, 1992. That year, President Bush declared a temporary moratorium on nuclear testing, which became permanent during the Clinton administration. This ending of the era of nuclear testing was also the beginning of stockpile stewardship. Leaders from the Department of Energy (DOE), and Lawrence…
Scientific discovery for stockpile stewardship
Scientific discovery during the Stockpile Stewardship Program maintains confidence in the nuclear deterrent without testing, brings other benefits The last nuclear test, code-named Divider, took place 30 years ago, on September 23, 1992. That year, President Bush declared a temporary moratorium on nuclear testing, which became permanent during the Clinton administration…
Developing technology to keep the nuclear stockpile safe, secure and reliable
The last nuclear test, code-named Divider, took place 30 years ago, on Sept. 23, 1992. That year, President Bush declared a temporary moratorium on nuclear testing, which became permanent in 1995, during the Clinton administration. This ending of the era of nuclear testing coincided with a Presidential announcement of the beginning of stockpile stewardship. As the decision…
LLNL leads new DART Mission paper on inferring asteroid material properties from deflection test
Today at 4:14 p.m. (PDT), NASA’s Double Asteroid Redirection Test (DART) Mission will execute the first-ever asteroid-deflection test by crashing into asteroid Dimorphos. Traveling at ~6 km/s with a mass of ~600 kg, the DART spacecraft will transfer enough momentum for the imparted change in velocity to be detectable from Earth-based telescopes. However, there is…
Team identifies parent body materials in Ryugu asteroid
An international team including a researcher from Lawrence Livermore National Laboratory (LLNL) has determined that one specific particle on the asteroid Ryugu can shed light on the unaltered initial materials from its parent body. In December 2014, the Japanese Aerospace Exploration Agency launched the spacecraft Hayabusa2 to the asteroid 162173 Ryugu. In December 2020,…
