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.

End of an era! @Livermore_Lab’s Sierra supercomputer is officially retired after years of powering innovation and discovery. Thank you for paving the way for the next generation of high-performance computing with El Capitan.

For High Energy Density Science Center fellow Patricia Cho, LLNL has allowed her to branch out from her Ph.D. work, exploring new areas of laboratory astrophysics and introducing new experimental approaches to probe cosmic mysteries.

Congrats to Wei Jia Ong for being recognized with @APSphysics’ 2025 Stuart Jay Freedman Award in Experimental Nuclear Physics for her study of X-ray bursts, in which a neutron star siphons and heats material from a companion star, triggering an explosion.

A new technique is allowing nuclear forensics researchers at LLNL and @BerkeleyLab to identify chemical states and material impurities at a resolution never before achieved. Explore the precision of synchrotron-based scanning transmission X-ray microscopy:

Introducing: Micro Impulse Radar (MIR). Created by @Livermore_Lab, you've seen MIR used for pre-collision detection—making parking easy. We also use MIR for home security, bridge inspection, and more. It's one of the most commercially successful licensed inventions from NNSA.

What are @Cisco x @NVIDIA doing for enterprise AI networking? At the Cisco Partner Summit 2025, @willeatherton (SVP @Cisco) joins @MattKimball_MIS (@MoorInsStrat) to explore how @Cisco x @NVIDIA are redefining enterprise networking — from Nexus Hyperfabric AI to scalable cloud

The Sidney Fernbach Postdoctoral Fellowship at LLNL is now accepting applications. The highly competitive position offers fellows the opportunity to pursue their own research agenda in an interdisciplinary environment, backed by world-class #HPC resources. https://t.co/wlept1dNaw

LLNL is committed to being a leader in responsible environmental stewardship. The 2024 Annual Site Environmental Report details monitoring results and describes environmental protection and remediation programs at both the Livermore site and Site 300. https://t.co/wiiOALmGev

For 20 years, LLNL’s Computing Grand Challenge Program has accelerated scientific discovery with unclassified supercomputing resources. In the latest issue of the Science &Technology Review, explore how supercomputing rises to grand scientific challenges: https://t.co/fj0OnmpJVX

LLNL is working with a local startup, DarmokTech, to enhance cost-effective energy storage and grid reliability in #California and beyond. The collaboration was awarded a $2 million grant by @CalEnergy to pursue recyclable, sodium polymer-based batteries. https://t.co/13bUuVUmN4

Securing U.S. leadership in emerging fusion technologies and innovation: @ENERGY announced $134M in funding to fuel the Fusion Innovation Research Engine (FIRE) collaboratives and Innovation Network for Fusion Energy (INFUSE) program.

Metal additive manufacturing could be revolutionary; however, the technology remains too unreliable for widespread adoption in manufacturing. Explore how LLNL is helping to solve this challenge, catching printing problems before it’s too late:

A small Moon rock collected by Apollo 17 is rewriting lunar history. New research led by @Livermore_Lab scientist Evan Bjonnes suggests the Serenitatis Basin formed roughly 300 million years earlier than previously thought.

Recently, LLNL employees gathered to celebrate the discovery of a new element: Grillium (Gr). From sizzling science to a curated spice selection, the Grillin’ & Chillin’ Unplugged event brought the Lab community together with tours, tunes and tasty bites.

That’s a wrap on Q3. Lots of exciting things happening at @FlyArcher, beginning with our acquisition of the Hawthorne Airport, which is strategically located in the heart of Los Angeles just miles from LAX, SoFi Stadium, downtown Los Angeles and Long Beach. We’re planting the

"Comics have a way of breaking through technical complexity and helping a broad audience understand why the Lab’s work matters." - John Jett In honor of #ComicBookDay, explore the story of how a Lab experiment at @lasers_llnl made history: https://t.co/NOGv5Gxrqn

High-repetition-rate lasers are not new, but challenges such as overheating and reliability issues are limiting their potential. In the #BigIdeasLab, discover how LLNL is tackling these issues with novel designs and new materials, like the BAT laser: https://t.co/zOIdwx5RRq

Outstanding leadership empowers our teams to pursue bold and innovative science and technology. LLNL is proud to be named one of @Glassdoor’s Best-Led Companies in the United States, earning the #32 spot on the 2025 list. #BestLedCompanies #GlassdoorsBest https://t.co/bzx3uV2J2e

#DidYouKnow @Livermore_Lab's Site 300 is home to the world’s largest indoor firing facility​? The Contained Firing Facility is designed to capture every aspect of an explosion and to completely contain the forces and environmental hazards released from an explosion.
