Lawrence Livermore National Laboratory

At #LLNL, the realm of what’s possible is only bounded by the questions we’re willing to ask. Our teams fearlessly and relentlessly pursue big ideas using innovative science and technology to meet our national security mission and to make the world a better place.

Join @Livermore_Lab on Saturday, April 18, at the 8th Annual Tri-Valley Innovation Fair. Meet with our expert scientists and participate in interactive #STEM activities at our exhibitor booth. Register now: livermorelab.info/40yq8XF

The open-source HYPRE software library provides specialized, scalable solvers for a range of purposes. Version 3 includes a new semi-structured AMG solver along with support for mixed numerical precision at runtime. computing.llnl.gov/about/newsroom…

#DidYouKnow LLNL's Jupiter Laser Facility is home to one of the world's few hands-on laser platforms producing kilojoules of energy? Follow the journey of JLF's three beamlines as they deliver high-energy pulses. Learn more: jlf.llnl.gov

Students, join @Livermore_Lab for the 2026 Science on Saturday series, "Computing the Future!” at the Grand Theatre in #Tracy, where we explore cutting-edge research conducted at the Lab. Register today: livermorelab.info/48S8uAl

A new issue of SpotLight is now available online. From kayaking through the backwoods to playing at local festivals, explore life outside the Lab for LLNL employees. spotlight.llnl.gov

Recently, @US_STRATCOM Commander U.S. Navy Adm. Rich Correll and Command Senior Enlisted Leader U.S. Army Command Sgt. Maj. Jo Naumann visited LLNL for a tour of the Lab's world-class facilities, where they got to see @lasers_llnl and the Independent Diagnostic Scoring System.

Congrats to an all-CASC team on the SIAM IMR Best Paper! Their research introduces new techniques to optimize curvilinear meshes for high-fidelity simulations. High-order r-adaptivity just got better! arxiv.org/pdf/2601.17708

A #90s throwback to LLNL: when the computers were bigger, the internet was slower but the science was already moving fast.

How could engineered yeast help strengthen the U.S. rare-earth supply chain? Researchers from LLNL and collaborators developed a microbial platform that produces oxalic acid, a key chemical used to separate and purify rare-earth elements. livermorelab.info/4sLkflL

In a flash, tiny targets, no bigger than a pencil eraser, are mostly obliterated in inertial confinement fusion experiments at @lasers_llnl. Explore these marvels of design, engineering and precision manufacturing in a new episode of the #BigIdeasLab: livermorelab.info/46W4Dnc

HPC-cloud computing just got a(nother) boost with @FluxFramework! Flux is now integrated into Kubeflow Trainer thanks to the hard work of @vsoch 🙌 computing.llnl.gov/projects/flux

For the first time, researchers at LLNL have developed a technique to simulate crystal defects at realistic temperatures, overcoming long-standing challenges in the field to calculate material structure and properties. livermorelab.info/4bqw4XG

We wanted to calculate the most digits of Pi with El Capitan, but apparently, there were higher priorities. Instead, we will just wish you a #HappyPiDay.

LLNL and @ENERGY are offering public tours this spring as part of the community involvement plans for the Livermore Site Groundwater Cleanup Project and Site 300 Groundwater Cleanup Project. Register today: livermorelab.info/4lsmp7j

Access to one supercomputer is a boon for researchers, but access to multiple supercomputers is even better! A multi-institutional team is using 700,000 node-hours to evaluate & develop LLMs in HPC programming settings. computing.llnl.gov/about/newsroom…

Congratulations to all thirty-six LLNL researchers who have been named Distinguished Members of Technical Staff in recognition of their extraordinary scientific and technical contributions, as affirmed by their peers and the broader scientific community. livermorelab.info/4ly2J23

A team led by LLNL identified several existing medications that may be associated with longer survival in people with #ALS. Out of the 162 medications evaluated, they found 27 medications associated with statistically significant changes in mortality risk. livermorelab.info/4loMbJT

Every target at @lasers_llnl is a science and engineering wonder. In the latest episode of the #BigIdeasLab, follow the journey of these tiny targets from their start as a high-density carbon shell right to the final destination in the NIF Target Chamber. livermorelab.info/46W4Dnc

At Lawrence Livermore National Laboratory, your role as a Power Systems Graduate Intern - Cyber and Critical Infrastructure Summer Institute - Summer 2026 is more than a job, it's a chance to contribute to world-changing advancements and innovation. bit.ly/40fzK9C
