James Strait Named Project Director of Next Generation Cosmic Microwave Background Project

Lawrence Berkeley National Laboratory (Berkeley Lab) has selected James (Jim) Strait, a Fermilab physicist with a long history of managing large international scientific projects, to serve as the Project Director of the next-generation experiment Cosmic Microwave Background Stage 4, also known as CMB-S4.

Physicists Announce First Results from Daya Bay’s Final Dataset

The Daya Bay Neutrino Experiment has produced the most precise measurement yet of theta13, a key parameter for understanding how neutrinos change their “flavor.” The result will help physicists explore some of the biggest mysteries surrounding matter and the nature of the universe.
