Laboratory researchers join their AI-enabled counterparts for 'collaborative autonomy'

Feb. 20, 2018 -  
A team of firefighters clears a building in a blazing inferno, searching rooms for people trapped inside or hotspots that must be extinguished. Except this isn’t your typical crew. Most apparent is the fact that the firefighters aren’t all human. They’re working side-by-side with artificially...

DOE's HPC4Manufacturing program seeks industry proposals for energy advances

Feb. 1, 2018 -  
The Department of Energy ( DOE ) on Feb. 1 announced up to $3 million will be available to U.S. manufacturers for public/private projects aimed at applying high performance computing to industry challenges for the advancement of energy innovation. The funding represents the latest round of...

Lab unlocks secrets of nanoscale 3D printing

Jan. 3, 2018 -  
Lawrence Livermore National Laboratory (LLNL) researchers have discovered novel ways to extend the capabilities of two-photon lithography (TPL), a high-resolution 3D printing technique capable of producing nanoscale features smaller than one-hundredth the width of a human hair. The findings,...

LLNL-developed microelectrodes enable automated sorting of neural signals

Dec. 12, 2017 -  
Thin-film microelectrode arrays produced at Lawrence Livermore National Laboratory (LLNL) have enabled development of an automated system to sort brain activity by individual neurons, a technology that could open the door to recording and analyzing unprecedented amounts of neural signals over time...

Volumetric 3D printing builds on need for speed

Dec. 8, 2017 -  
While additive manufacturing (AM), commonly known as 3D printing, is enabling engineers and scientists to build parts in configurations and designs never before possible, the impact of the technology has been limited by layer-based printing methods, which can take up to hours or days to build three...

LLNL project aims to transform electrical grid resiliency with distributed energy resources

Sep. 28, 2017 -  
In the event of a major earthquake, hurricane or flood, electricity might be lost for days, affecting communications, recovery efforts and people’s lives. Normally, in a large-scale emergency, distributed energy resources (DERs) -- such as the energy produced by solar panels at customers’ homes --...
