Fentanyl or phony? Machine-learning algorithm learns to pick out opioid signatures
New forms of fentanyl are created every day. For law enforcement, that poses a challenge: how do you identify a chemical you’ve never seen before? Researchers at Lawrence Livermore National Laboratory (LLNL) aim to answer that question with a machine-learning model that can distinguish opioids from other chemicals with an accuracy over 95% in a laboratory setting. The…
Simulations and supercomputing calculate one million orbits in cislunar space
Satellites and spacecraft in the vast region between the earth and moon and just beyond — called cislunar space — are crucial for space exploration, scientific advancement and national security. But figuring out where exactly to put them into a stable orbit can be a huge, computationally expensive challenge. In an open-access database and with publicly available code,…
LLNL’s energy scale-up brainstorming event focused on accelerating pilot-ready technologies
Solving tomorrow’s challenges in energy security requires scientists to develop new pathways to streamline innovation. To help achieve this goal, the Global Security Directorate at Lawrence Livermore National Laboratory (LLNL) recently hosted an “Energy Scale-up Brainstorming Day.” More than 60 researchers across a broad range of expertise gathered to engage in interactive…
Discover LLNL’s Autonomous Sensors program in the latest episode of the Big Ideas Lab podcast
When disaster strikes, every second counts, but sometimes the danger is too great for humans to go first. From mapping terrain to reaching deep underground to detect hidden threats and abandoned wells, unmanned systems equipped with advanced sensors are changing how we respond to crises. Across land, air and sea, drones can act as one coordinated force to increase the…
Walk in the shoes of an offsite fellow with the Big Ideas Lab podcast
Walk through any federal building and you might spot them. A Livermore face among the crowd. Not visitors. Not consultants. Fellows. Some are sent to Washington, others remain local in Silicon Valley, and a select few even concentrate their efforts toward the final frontier: space. But whether D.C. or deep space, Lawrence Livermore National Laboratory (LLNL) brings its…
Big Ideas Lab takes a closer look at NARAC
It’s been 45 years since the first emergency phone call from the Department of Energy came into Lawrence Livermore National Laboratory (LLNL) to activate a new atmospheric modeling center that predicts the effects of hazardous plumes. Listen on Apple or Spotify. An accident had occurred at the Three Mile Island nuclear power plant in Pennsylvania on March 28, 1979, that…
LLNL's Buddemeier named to National Academies board
Lawrence Livermore National Laboratory (LLNL) certified health physicist Brooke Buddemeier has been appointed to a panel of the National Academies of Sciences, Engineering and Medicine. A 35-year Lab employee, Buddemeier has been named to the Nuclear and Radiation Studies Board (NRSB), which provides advice about safety, security, technical efficacy and other issues…
Americans increase overall pace of decarbonization, but state trends vary
In 2023, Americans reduced their consumption of electricity and fossil fuels, while increasing consumption of carbon-free energies, according to the most recent energy and carbon flowcharts released by Lawrence Livermore National Laboratory (LLNL). Each year, LLNL releases these flowcharts to illustrate the nation's consumption and uses of energy, as well as associated CO2…
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…
Deep Purple payload successfully deployed and operational
The Deep Purple telescope developed by Lawrence Livermore National Laboratory (LLNL) researchers is now operational in space. The Livermore instrument, which utilizes a new design for an ultra-violet (UV) and short-wave infrared monolithic telescope features a novel, compact optical system and electronics package inside a lightweight, modular housing. On Friday, Aug. 16,…
Lab team surveys Site 300 for hotspots
In the mid-afternoon of Saturday, June 1, the Corral Fire ignited near the Lab’s Site 300. It made headlines for days and kicked off this year’s fire season. The blaze raced across more than 14,000 acres in just 24 hours, incinerated a structure and badly burned two fire personnel. Early Sunday morning, the Lab’s Associate Principal Deputy Director Sandra Brereton reached…
LLNL delivers compact dual-band telescope for launch this summer
Lawrence Livermore National Laboratory’s (LLNL) space hardware team has delivered a payload for NASA’s Pathfinder Technology Demonstrator-R (PTD-R) satellite. LLNL developed the optical payload, called Deep Purple, that utilizes a new design for an ultra-violet (UV) and short-wave infrared (SWIR) monolithic telescope. The mission will demonstrate simultaneous monolithic UV…
LLNL gamma-ray sensor has the best resolution
It’s official. An instrument designed and built by Lawrence Livermore National Laboratory (LLNL) researchers is the highest-resolution gamma ray sensor that has ever flown in space. The Livermore high-purity germanium (HPGe) gamma ray sensor is an essential part of a larger gamma-ray spectrometer (GRS) built in collaboration with researchers from Johns Hopkins Applied…
Signal and image science community comes together for annual workshop
Nearly 150 members of the signal and image science community recently came together to discuss the latest advances in the field and connect with colleagues, friends and potential collaborators at the 28th annual Center for Advanced Image and Signal Science (CASIS) workshop. Held at the University of California Livermore Collaboration Center (UCLCC) for the first time, the…
FAA awards first approval for drone swarm testing
Lawrence Livermore National Laboratory’s (LLNL) Autonomous Sensors team has received the Federal Aviation Administration’s (FAA’s) first and — to date — only certificate of authorization (COA) allowing autonomous drone swarming exercises on the Lab main campus. These flights will test swarm controls and sensor payloads used in a variety of national security applications…
Lab to provide optical payload for upcoming U.S. Space Force mission
Lawrence Livermore National Laboratory’s (LLNL) Space Program is now building an optical space domain awareness payload for an upcoming mission by the U.S. Space Force. The planned mission, known as VICTUS HAZE, will be a tactically responsive space mission to demonstrate the ability to rapidly characterize an on-orbit threat. The U.S. Space Force selected Long Beach,…
LLNL Pandora SmallSat mission clears major NASA milestone on the path toward launch
Lawrence Livermore National Laboratory’s (LLNL) Pandora SmallSat mission recently passed NASA’s critical design review: a major milestone for the mission to continue its journey toward launch. The Pandora SmallSat mission will study planets beyond our solar system, known as exoplanets, and their stars. “This is a major milestone for the mission and a huge accomplishment…
Hydrogen storage demonstrated for semi trucks
Lawrence Livermore National Laboratory (LLNL) and Verne, a San Francisco-based startup, have demonstrated a cryo-compressed hydrogen storage system of suitable scale for heavy-duty vehicles.
