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

Sept. 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 --...

LLNL and LBNL researchers explore more energy-efficient solutions for paper industry

May 16, 2017 -  
If you had to name the industries in the United States that use the most energy, paper manufacturing probably wouldn’t immediately come to mind. In fact, the paper-making industry ranks third among the country’s largest energy users, behind only petroleum-refining and chemical production, according...

Lawrence Livermore unveils 'heart-on-a-chip'

May 11, 2017 -  
Prescription drugs have enabled millions of Americans with chronic medical conditions to live longer and more fulfilling lives, but many promising new drugs never make it to the human trials stage due to the potential for cardiac toxicity. Through “heart-on-a-chip” technology — modeling a human...
