Understanding the universe through neutrinos

Jul. 13, 2018 -  
Determining features of the elusive particle known as a neutrino – through the observation of an extremely rare nuclear process called neutrinoless double-beta decay (NDBD) -- could provide a glimpse into the nature of the universe during the earliest moments of the Big Bang. As part of an...

LLNL part of team studying protein filaments

May. 25, 2018 -  
To learn more about diseases such as Alzheimer’s and Parkinson’s, scientists have zeroed in on invisibly small protein filaments that bunch up to form fibrous clusters called amyloids in the brain: How do these fibrils form and how do they lead to disease? Until now, the best tools for studying...
