LZ dark matter experiment sets a world’s best and spots neutrinos from the sun’s core
There’s more to the universe than meets the eye. Dark matter, the invisible substance that accounts for 85 percent of the mass in the universe, is hiding all around us — and figuring out exactly what it is remains one of the biggest questions about how our world works. The newest results from LUX-ZEPLIN (LZ) extend the experiment’s search for low-mass dark matter and set…
Turning wastewater into valuable fertilizer
Almost half of the planet’s population depends on synthetic fertilizers to grow the food they eat. But that fertilizer comes at a cost — about two percent of the world’s energy budget. Improving efficiency and cutting costs of producing fertilizer would have big, global impacts. To that end, researchers at Lawrence Livermore National Laboratory (LLNL) are developing a…
Meteorite samples are time capsules from the early solar system
When a meteor streaks across the sky, it’s not just beautiful. It’s nature’s way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our own, formed. Lawrence Livermore National Laboratory (LLNL) scientist Thomas Kruijer and collaborators describe how meteorites tell the story of the…
LLNL, UT & UCSD win Gordon Bell Prize with exascale tsunami forecasting
Researchers at Lawrence Livermore National Laboratory (LLNL), the University of Texas at Austin’s (UT) Oden Institute and Scripps Institution of Oceanography at the University of California San Diego (UCSD) on Nov. 20 were awarded the prestigious 2025 Association for Computing Machinery (ACM) Gordon Bell Prize for developing a real-time tsunami early-warning framework…
Volcanic eruptions trigger ice formation in clouds
When a volcano erupts, it can spew ash high into the atmosphere — injecting aerosols right where clouds typically form. How exactly these aerosols impact cloud formation has long been a mystery to atmospheric scientists. In a study published in Science Advances, researchers from Lawrence Livermore National Laboratory (LLNL) analyzed 10 years of satellite data to determine…
LLNL supports CO2 storage in California’s delta
The U.S. Department of Energy’s Office of Fossil Energy and Carbon Management (FECM) has awarded $6 million to Lawrence Livermore National Laboratory (LLNL) researchers, as part of a $45.2 million award to a team led by Pelican Renewables LLC, to develop a regional CO2 storage hub in California’s Sacramento-San Joaquin Delta in California. The funding came through FECM’s…
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…
Ramping up the scale of climate and energy technology
One of the biggest challenges implementing energy and climate technologies is actually scaling it up to deploy it. While scale-up has largely been the domain of industrial R&D teams, advances in modelling and experimental techniques increasingly allow early-stage researchers like those at Lawrence Livermore National Laboratory (LLNL) to contribute to the process. In a…
Lawrence Livermore National Laboratory’s El Capitan verified as world's fastest supercomputer
Lawrence Livermore National Laboratory (LLNL), in collaboration with the National Nuclear Security Administration (NNSA), Hewlett Packard Enterprise (HPE) and AMD, have officially unveiled El Capitan as the world's most powerful supercomputer and first exascale system dedicated to national security. Verified at 1.742 exaFLOPs (1.742 quintillion calculations per second) on…
Kim Budil, LLNL named in inaugural Top 100 climate list
Lawrence Livermore National Laboratory (LLNL) Director Kim Budil and the team that achieved fusion in 2022 have been named to The Independent’s inaugural Climate 100 list, which highlights climate activists, innovators, scientists, business leaders, creators, policymakers and entrepreneurs involved in the fight against climate change. Budil and the Lab are recognized for…
Getting into the details of carbon accounting
Carbon dioxide removal (CDR) is essential for climate change mitigation, but no single standardized methodology exists for evaluating project-level net carbon removal from the atmosphere. Lawrence Livermore National Laboratory (LLNL) scientists and collaborators from Lawrence Berkeley and National Renewable Energy national laboratories and UC Berkeley, have looked into the…
All ears on the Big Ideas Lab podcast
Lawrence Livermore National Laboratory (LLNL) has big ideas and is showing the world in the Big Ideas Lab weekly podcast that takes listeners behind the fences and into its heart. “This is where big ideas come to life,” said Lab Director Kim Budil. “To do this, we bring together dynamic teams of many different disciplines — laser physicists and materials scientists and…
Tropical forests feel the burn of climate change
Tropical forests account for more than 50% of the global terrestrial carbon sink, but climate change threatens to alter the carbon balance of these ecosystems. New research by Lawrence Livermore National Laboratory (LLNL) scientists and colleagues from Colorado State University and the Smithsonian Tropical Research Institute found that warming and drying of tropical forest…
Greenland ice sheet melted in recent past
Greenland was once actually green — even if it was close to a million years ago. But its lack of an ice sheet back then may lead to clues about the increased risk of sea-level rise in a warmer future. A new study provides the first direct evidence that the center, not just the edges, of Greenland’s ice sheet melted away in the recent geological past and the now-ice-covered…
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…
It’s all in the accounting
Natural ecosystems can be used to offset manmade CO2 and other greenhouse gas emissions that we add to the atmosphere, but the accounting needs to be right for carbon offset policies to be effective. For years, it’s been suspected that forest inventory and, more recently, biometeorological methods bias the carbon sequestration equation by potentially miscounting the…
Three selected as Graduate Student Research program recipients
Three graduate students have earned Department of Energy (DOE) Office of Science Graduate Student Research (SCGSR) Program awards to perform their doctoral dissertation research at Lawrence Livermore National Laboratory (LLNL). The prestigious award helps cover living expenses and travel for 60 students from universities across the nation. Their proposed research projects…
A pattern of temperature change emerges from natural climate fluctuations
When comparing model simulations of Earth’s recent warming to real-world observations, differences can arise from several factors, including model errors in the simulated response to increased greenhouse gases and natural fluctuations within the climate system. Natural climate variability, also called internal variability, can change regional and global atmospheric…
Unexpected source of nutrients fuels growth of toxic algae from Lake Erie
Climate change, such as warming and changes in precipitation patterns, affects the frequency and severity of harmful algal blooms (HABs) globally, including those of toxin-producing cyanobacteria that can contaminate drinking water. These nutrient-induced blooms cause worldwide public and ecosystem health concerns. Since the mid-1990s, Lake Erie, the shallowest and warmest…
