2016 Breakthrough Prize in Fundamental Physics Goes to Five Neutrino Experiments, Three Made Possible by Berkeley Lab

On November 8, Silicon Valley’s ritzy, glitzy 2016 Breakthrough Prizes honored five neutrino experiments with $3 million prizes in Fundamental Physics. Three of the five, SNO, KamLAND, and Daya Bay, were made possible by Berkeley Lab scientists and engineers.

Supernova Twins: Making Standard Candles More Standard Than Ever

Type Ia supernovae are bright “standard candles” for measuring cosmic distances. Standard enough to discover dark energy, they’re far from identical. Researchers at the Berkeley Lab-based Nearby Supernova Factory have shown that supernova twins with closely matching spectra double the accuracy of distance measures.

2015 Nobel Prize in Physics Has Berkeley Lab Roots

Berkeley Lab scientists and engineers played important roles in the design and construction of SNO – the Sudbury Neutrino Observatory – as well as subsequent data analysis that contributed to the 2015 Nobel Prize in Physics awarded to Canada’s Arthur McDonald.

DESI, an Ambitious Probe of Dark Energy, Achieves its Next Major Milestone

The U.S. Department of Energy has announced approval of Critical Decision 2 (CD–2), authorizing the scientific scope, schedule, and funding profile of DESI, the Dark Energy Spectroscopic Instrument, an exceptional apparatus designed to improve our understanding of the role of dark energy in the expansion history of the universe.

Best Precision Yet for Neutrino Measurements at Daya Bay

In the Daya Bay region of China a research project is underway to study ghostlike, elusive particles called neutrinos. Today, the international Daya Bay Collaboration announces new findings on the measurements of neutrinos, paving the way forward for further neutrino research, and confirming that the Daya Bay neutrino experiment, significant as the first equal partnership between the U.S. and China in a major physics project, continues to be one to watch.

Notes from the Particle Physics Underground

The town of Lead South Dakota has a hidden gem: an enormous, underground mine that’s been retrofitted to accommodate large-scale particle physics experiments. These slideshows and videos give a sense of what it’s like to descend 4,850 feet below the surface and work on projects that could shine light on fundamental truths about the universe.

New Visitor Center in South Dakota Highlights Underground Science

The Sanford Lab Homestake Visitor Center, a facility that highlights Homestake Mine’s gold and silver past and particle physics future, held its grand opening ceremony on June 30.

How a New Telescope Will Measure the Expansion of the Universe

Michael Levi and David Schlegel, physicists at Berkeley Lab, discuss the future of the DESI project and how its forthcoming map will help scientists better understand dark energy.

National Security on the Move with High Energy Physics

Scientists are developing new technology that will safely and quickly detect nuclear material in large objects such as cargo containers.

For Ultra-cold Neutrino Experiment, a Successful Demonstration

An international team of nuclear physicists announced the first scientific results from the Cryogenic Underground Observatory for Rare Events (CUORE) experiment. CUORE is designed to confirm the existence of the Majorana neutrino, which scientists believe could hold the key to why there is an abundance of matter over antimatter.
