Americans ramp up use of solar, wind energy

April 24, 2018 -  
Americans used more solar and wind energy in 2017 compared to the previous year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory (LLNL). Overall, energy consumption by the residential and commercial sectors dropped a bit. Each year, the Laboratory...

The definitive search for axion dark matter

April 9, 2018 -  
Forty years ago, scientists theorized a new kind of low-mass particle that could solve one of the enduring mysteries of nature: what dark matter is made of. The search for that particle has just begun. This week, the Axion Dark Matter Experiment (ADMX) unveiled a new result (published in the April...
