Sizing up the ever-elusive neutrino
About 100 trillion neutrinos are passing through your body at this very second. The particles are the second most abundant form of matter in the universe (behind light), but they interact very, very rarely. That property makes them ideal objects for studying the fundamentals of quantum mechanics; however, it also complicates measurements. For example, neutrinos were…
Assessing groundwater contamination risks near the Zaporizhzhia Nuclear Power Plant
As the war in Ukraine continues, the risk of environmental disasters grows, particularly around critical infrastructure like the Zaporizhzhia Nuclear Power Plant (NPP). LLNL and collaborators recently conducted a study, published in ACS EST Water, to assess the vulnerability of groundwater contamination in the region surrounding the nuclear power plant, using a model…
Quantum computers successfully model particle scattering
Scattering takes place across the universe at large and miniscule scales. Billiard balls clank off each other in bars, the nuclei of atoms collide to power the stars and create heavy elements, and even sound waves deviate from their original trajectory when they hit particles in the air. Understanding such scattering can lead to discoveries about the forces that govern the…
LLNL hosts Nuclear Science and Security Consortium workshop
Once a year, a community of university professors, students and national lab researchers who focus on nuclear science and security gather to share research updates and develop collaborations, among other tasks. The group — known as the Nuclear Science and Security Consortium (NSSC) — recently held its workshop at the Lawrence Livermore National Laboratory (LLNL). The NSSC…
Three LLNL scientists honored with presidential early-career award
In an announcement this week, President Biden awarded the Presidential Early Career Award for Scientists and Engineers (PECASE) to nearly 400 distinguished scientists and engineers, recognizing their exceptional contributions and potential for leadership in their research fields. Among the honorees are three distinguished researchers from Lawrence Livermore National…
Samples from the surface needed to unravel history of Mars
Geologically, Mars is very reminiscent of the moon. But it also looks a lot like the Earth. It all depends on who you ask. Current understanding of Mars’ evolution is based on spacecraft measurements and meteorite analysis. Those meteorites were ejected from Mars and traversed space before landing on Earth, where they were discovered primarily in African deserts and…
Big Ideas Podcast tackles the road to carbon removal
Lawrence Livermore National Laboratory (LLNL) has released a new episode of the Big Ideas Lab Podcast, focusing on the critical efforts being made to help remove carbon dioxide from the atmosphere. The episode provides insights into how 68 researchers nationwide came up with a comprehensive analysis of the capacity and costs for carbon dioxide removal at a county level…
'Lighting' up antineutrino detection
How do you find and measure nuclear particles, like antineutrinos, that travel near the speed of light? Antineutrinos are the antimatter partner of a neutrino, one of nature’s most elusive and least understood subatomic particles. They are commonly observed near nuclear reactors, which emit copious amounts of antineutrinos, but they also are found abundantly throughout the…
LLNL’s Gauthier Deblonde selected as ‘Rising Star’
Lawrence Livermore National Laboratory (LLNL) staff scientist Gauthier Deblonde has been named a 2024 “Rising Star“ by the American Chemical Society for his work in environmental science. Deblonde’s research as well as this year’s cohort of winners will be featured in a special issue of the American Chemical Society journal ACS Environmental Au. Deblonde’s research also…
LLNL internship sets chemistry student on the right PATH
Internships at Lawrence Livermore National Laboratory (LLNL) provide graduate students with hands-on research experience that they can bring back to their home institutions, applying their newfound skillsets to their PhD work. Since interning for LLNL’s Glenn T. Seaborg Institute in 2023, Zachary Murphy, a PhD student at the University of Central Florida (UCF), has gone on…
Becoming a nuclear scientist: LLNL traineeship inspires SJSU students
Historically, most undergraduate students in STEM are limited in their exposure to the field of nuclear science. This is especially true at minority-serving institutions, which often do not have the infrastructure, resources and technical support needed to maintain such courses. To broaden the nuclear science pipeline and establish an equitable and inclusive workforce that…
DOE honors seven early-career Lab scientists
Seven scientists from Lawrence Livermore National Laboratory (LLNL) are recipients of the Department of Energy’s (DOE) Office of Science Early Career Research Program (ECRP) award. Steven Blazewicz, Kostas Kravvaris, Shusen Liu, Filippo Scotti, Jennifer Shusterman, Kyle Wendt and Ben Zhu are among 91 awardees receiving the recognition under the program. “Investing in…
Experiment sets new record in search for dark matter
Figuring out the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world’s most sensitive dark matter detector, LUX-ZEPLIN (LZ), have narrowed down possibilities for one of the leading dark matter candidates: weakly interacting massive particles, or WIMPs. LZ, led…
Revolutionizing Quantum Science
In recent years, Lawrence Livermore has increased efforts in quantum information science, a multidisciplinary field aimed at applying the scientific theories underpinning quantum mechanics to problems of extraordinary computational magnitude and precision sensing.
Chemical and transportation industries could get a boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources — such as solar and wind — promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene, ethanol and acetic acid are particularly useful as feedstocks for the chemical industry and powering vehicles. While…
Meet LLNL interns: Fitting in and standing out
Each year, Lawrence Livermore National Laboratory (LLNL) hosts hundreds of interns across the Laboratory’s directorates. These interns gain hands-on experience in professions they want to explore in an engaging environment. As aspiring early career professionals, interns have the opportunity to work with their mentors at the Lab and dive into projects that will help…
Unveiling Bennu asteroid samples
Now at Lawrence Livermore National Laboratory (LLNL) lies a piece of ancient history. Very ancient history. The material, at just 120 milligrams, will provide information about the early solar system, planetary formation, and potentially, even ingredients for life on ancient Earth. LLNL scientists recently received and will analyze samples from the asteroid Bennu that will…
Unravelling the chemistry of heavy elements
Molecular compounds with heavy elements, like americium, curium and others can now be synthesized in a streamlined and efficient way thanks to a new technique developed by Lawrence Livermore National Laboratory (LLNL) researchers. The new pathway can help scientists perform serial chemistry with radioactive elements and could be used to speed up R&D for nuclear waste…
Lawrence Livermore celebrates employees with 50-plus years of service
Lawrence Livermore National Laboratory (LLNL) recently honored a unique cohort of Laboratory employees: those who have worked at the Lab for more than 50 years, including those who will reach this milestone by the end of the year.
