Researchers developing deep learning system to advance nuclear nonproliferation analysis
Artificial neural networks are all around us, deeply embedded in routine functions on the internet. They help online merchants make personalized shopping recommendations, enable social media sites to recognize faces in photos and assist email programs in filtering out spam. Neural networks also have the potential to play a critical role in national security, helping…
Optogenetics – controlling neurons with light – may lead to cures for PTSD, Alzheimer's
Through the emerging field of optogenetics, a technology that allows genetically modified neurons in living tissue to be precisely controlled by means of light, scientists are attempting to gain a better understanding of how the brain works in hopes of discovering cures for debilitating neural disorders such as post-traumatic stress disorder (PTSD) and Alzheimer’s disease…
LLNL and Virginia Tech researchers achieve more complex 3D-printed graphene aerogel
Graphene aerogel is lighter than air but as strong as steel, and it’s already proven useful in aerospace, energy storage and insulation. While there have been recent advances in 3D printing of the novel material, achieving complex structures has been elusive, hampering the unique material’s full potential. To date, 3D printing of graphene aerogel has been done using direct…

Research by Lawerence Livermore scientists may help validate organ-on-a-chip devices
A new study in which Lawrence Livermore National Laboratory (LLNL) scientists compared drug responses in the brains of rodents to drug responses of brain cells cultured in Lab-developed "brain-on-a-chip" devices may be a critical first step to validating chip-based brain platforms, LLNL researchers said. In the study, published online today in the journal Scientific…
Warhead life extension passes key milestone
The program to extend the life of the W80 nuclear warhead recently achieved a significant milestone when the National Nuclear Security Administration (NNSA) gave passing grades to the plans to refurbish certain components and the proposed approach to developing component cost estimates. Passing the milestone confirms that the life extension program (LEP), dubbed the W80-4…
Former LLNL engineer turned NASA astronaut inspires employees to 'reach for the stars'
Growing up in the Central Valley, the son of Mexican migrant farmworkers, José Hernández learned early on that education would be his ticket out of a life toiling in the fields. His journey would lead him to a 15-year career at Lawrence Livermore National Laboratory (LLNL), to the zero-gravity of low-earth orbit aboard the space shuttle Discovery, and to a congressional…
