Experiment improves predictions of uranium dispersion

May 4, 2020- 
The predictive models that describe the fate and transport of radioactive materials in the atmosphere following a nuclear incident (explosion or reactor accident) assume that uranium-bearing particulates would attain chemical equilibrium during vapor condensation. In a new study, funded by the Office of Defense Nuclear Nonproliferation Research and Development (DNN R&D) within the U.S...

Guidance regarding extended shelter-in-place orders

May 1, 2020- 
Local, state and national response to the COVID-19 pandemic continues to evolve, with the state of California establishing a four-stage plan to slowly modify its shelter-in-place order and Bay Area counties extending their shelter-in-place orders through May. Under the extended Alameda County order, current restrictions will largely remain, with limited easing for a small number of lower-risk...

LLNL’s new machine learning platform generates novel COVID-19 antibody sequences for experimental testing

May 1, 2020- 
Lawrence Livermore National Laboratory (LLNL) researchers have identified an initial set of therapeutic antibody sequences, designed in a few weeks using machine learning and supercomputing, aimed at binding and neutralizing SARS-CoV-2, the virus that causes COVID-19. The research team is performing experimental testing on the chosen antibody designs. Currently, treating COVID-19 with...

Lab researchers, NASA find space station’s surface microbial profile resembles skin of its crew members

April 30, 2020- 
A study conducted by a team of national laboratory and NASA researchers has found that the environment of the International Space Station is affected by the microbial composition of the astronauts themselves. The five-year research effort represents the first study to compare the space station's environmental microbial profile (or microbiome) to an astronaut’s microbiome using metagenomic...

LLNL develops ‘stopgap’ ventilator for COVID-19 use

April 29, 2020- 
While hospitals across the U.S. faced a possible shortage of mechanical ventilators due to COVID-19, a self-assembled “skunk works” team at Lawrence Livermore National Laboratory (LLNL) worked tirelessly to prototype a simple ventilator design for quick and easy assembly from available parts. Dubbed the “Novel Emergency Response Ventilator” (NERVe), the design is derived from proven...

LLNL researchers salvage broken arrow samples

April 27, 2020- 
It was a cool spring day in May 2019. LLNL researchers Mark Hart, Matt Lyman and Salustra Urbin were combing through rusted propellers and a split Mk4 bomb case in the foothills of Manzano Mountain, just a few miles east of Kirtland Air Force Base in New Mexico. The LLNL team was exploring three different plane crashes that had occurred on the mountain, but it was the remnants from a “broken...
