World’s Most Sensitive Dark Matter Detector Completes Search

The Large Underground Xenon (LUX) dark matter experiment, which, with the help of Berkeley Lab researchers, operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its search for the missing matter of the universe. At a meeting in the UK, LUX scientific collaborators presented the results from the detector’s final 20-month run.

Dark Energy Measured with Record-Breaking Map of 1.2 Million Galaxies

A team of hundreds of physicists and astronomers, including those from Berkeley Lab, have announced results from the largest-ever, three-dimensional map of distant galaxies. The team constructed this map to make one of the most precise measurements yet of the dark energy currently driving the accelerated expansion of the Universe.

$40M to Establish New Observatory Probing Early Universe

A new astronomy facility, the Simons Observatory, is planned in Chile’s Atacama Desert to boost ongoing studies of the evolution of the universe, from its earliest moments to today. The observatory will probe the subtle properties of the universe’s first light, known as cosmic microwave background radiation.

Scientists Take a Major Leap Toward a ‘Perfect’ Quantum Metamaterial

Scientists have devised a way to build a “quantum metamaterial”—an engineered material with exotic properties not found in nature—using ultracold atoms trapped in an artificial crystal composed of light.

Most Precise Measurement of Energy Range for Particles Produced by Nuclear Reactors Reveals Surprises

An international team that includes researchers from Berkeley Lab has captured the most precise—and puzzling—energy measurements yet of ghostly particles called reactor antineutrinos produced at a nuclear power complex in China.

New Results from World’s Most Sensitive Dark Matter Detector

A new set of calibration techniques employed by LUX scientists has again dramatically improved the detector’s sensitivity.

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.
