On the hunt: HR’s ‘Talent Sourcers’ use a proactive approach to locating unique, hard-to-find applicants

With an abundance of applicants for about 500 job postings open on average at any given time, it’s clear that plenty of people are interested in working at the Lab. However, as recruiters know, for highly specialized jobs in STEM, locating the right person can be akin to finding a needle in a haystack. That’s where talent sourcers come in. Using various research methods, they find, engage...

Computational Engineering is key to ignition success

In a room illuminated by blinking lights and glowing monitors, more than 2,000 synchronized computers are triggered to run 5 million lines of code. The intricate code language is responsible for aligning and firing 192 laser beams — and carrying some 800 channels of target diagnostic data — efficiently and reliably several times a day. This isn’t a scene from a science fiction movie: it’s the...

Prototype telescope designed by Lawrence Livermore researchers launched to the International Space Station

A prototype telescope designed and built by Lawrence Livermore National Laboratory (LLNL) researchers has been launched from Cape Canaveral, Fla., to the International Space Station (ISS). Known as the Stellar Occultation Hypertemporal Imaging Payload (SOHIP), the telescope uses LLNL patented-monolithic optics technology on a gimbal to observe and measure atmospheric gravity waves and...

Breaking it down, carbon nanotube style

When it comes to studying particles in motion, experimentalists have followed a 100-year-old theory that claims the microscopic motion of a particle is determined by random collisions with molecules of the surrounding medium, regardless of the macroscopic forces that drive that motion. Scientists at Lawrence Livermore National Laboratory (LLNL) and the Massachusetts Institute of Technology...

First-ever hybrid Women in Data Science Livermore event celebrates achievements, supports women in the field

Celebrating International Women’s Day on March 8, Lawrence Livermore National Laboratory (LLNL) women data scientists, Lab employees and other attendees interested in the field gathered at the Livermore Valley Open Campus for the annual Livermore Women in Data Science (WiDS) regional event held in conjunction with the global WiDS conference. Attendees met online and in-person for the forum...

Demonstrating energy-efficient conversion of nitrate pollutants into ammonia

The nitrate runoff problem, a source of carcinogens and a cause of suffocating algal blooms in U.S. waterways, may not be a harbinger of doom. A new study led by the University of Illinois Urbana-Champaign and researchers from Lawrence Livermore National Laboratory (LLNL) demonstrates an approach for the integrated capture and conversion of nitrate-contaminated waters into valuable ammonia...

Registration open for all LLNL summer education programs

Registration is now open for Lawrence Livermore National Laboratory’s (LLNL’s) summer science education programs. Programming for the summer of 2023 includes hands-on experiences for students that relate to several research themes at LLNL. In addition, the Teacher Research Academy will equip educators with new resources to apply in their own classroom. STEM with Smartphones | June 12...

Ignition experiment advances stockpile stewardship mission

Third in a series of articles describing the elements of the National Ignition Facility’s fusion breakthrough. When scientists at Lawrence Livermore National Laboratory (LLNL) achieved fusion ignition at the National Ignition Facility (NIF) on Dec. 5, 2022 — an extraordinary scientific breakthrough that was decades in the making — the primary mission and driving goal behind the experiment...

High-fidelity simulation offers insight into 2013 Chelyabinsk meteor

On the morning of Feb. 15, 2013, a small asteroid exploded over Chelyabinsk, Russia, sending a loud shockwave and sonic boom across the region, damaging buildings and leaving around 1,200 people injured. The resulting meteor, with a diameter of approximate 20 meters (roughly the size of a six-story building), was one of the largest to be detected breaking up in the Earth’s atmosphere in more...

Novel experimental platform enables first measurements of ion-acoustic wave bursts during magnetic reconnection

A series of experiments conducted at the Omega Laser, part of the University of Rochester’s Laboratory for Laser Energetics, provide new insights into magnetic reconnection, a process that could help explain stellar flares and other astrophysical phenomena. The research confirmed that unstable ion-acoustic waves (IAWs) could be important to further understanding of the dissipation physics...

All eyes on Lynda Tesillo

For Lynda Tesillo, Women’s History Month means more than reflecting on the past. Her path to Lawrence Livermore National Laboratory started with studying engineering at a university — a decision which put her in a unique position within her family. “We had limited resources growing up, particularly when it came to affording an education,” Tesillo said. “At the time, my mother...
