5,000 Robots Merge to Map the Universe in 3D
How do you create the largest 3D map of the universe? It’s as easy as teaching 5,000 robots how to “dance.” DESI, the Dark Energy Spectroscopic Instrument, is an experiment that will target millions of distant galaxies by automatically swiveling fiber-optic positioners (the robots) to point and gather their light. In creating this detailed map, scientists hope to learn more about dark energy, which is driving the accelerating expansion of the universe. More>
Acrylic Tanks Provide Clear Window Into Dark Matter Detection
Scientists have a new window into the search for dark matter – an acrylic vessel that features a grouping of 12-foot-tall transparent tanks with 1-inch-thick walls. The tanks, which will surround a central detector for a nearly mile-deep experiment under construction in South Dakota called LUX-ZEPLIN (LZ), will be filled with liquid that produces tiny flashes of light in some particle interactions.

Black Holes Ruled Out as Universe’s Missing Dark Matter
For one brief moment after the 2015 detection of gravitational waves from colliding black holes, astronomers held out hope that the universe’s mysterious dark matter might consist of black holes sprinkled throughout the universe. UC Berkeley and Berkeley Lab physicists Uros Seljak and Miguel Zumalacárregui have dashed those hopes. More>
Berkeley Lab to Push Quantum Information Science Frontiers With New Programs in Computing, Physics, Materials, and Chemistry
A series of DOE Office of Science awards announced today significantly expand Berkeley Lab’s efforts in quantum information science – ... More»
NSF Institute to Include Lab Physicists in Big Data R&D
With $25 million in funding, the National Science Foundation’s Institute for Research and Innovation in Software will develop systems to help manage the large amounts of data produced by the Large Hadron Collider (LHC). As part of this effort, Lab physicist Heather Gray and other Lab scientists (in association with UC Berkeley) will focus on reconstructing the paths of particles produced in LHC experiments. More>
High-Energy Nuclear Collisions, Large-Scale Computing Aid Study of Early Universe
ALICE (A Large Ion Collider Experiment) is a detector in the Large Hadron Collider (LHC) ring designed to investigate quark-gluon plasma, the primitive matter that filled the early universe. Berkeley Lab’s Nuclear Science Division, in partnership with IT's Scientific Computing Group, has recently established a new site on the Worldwide LHC Computing Grid to provide a significant amount of ALICE computing and data storage.

APS Publishes 60th Anniversary Edition of the Review of Particle Physics
The latest edition of the Review of Particle Physics, a go-to resource for particle physicists published Aug. 17 in the American Physical Society's Physical Review D journal, marks the 60th anniversary of the founding of the Berkeley Lab-based Particle Data Group that produces the Review. More>
Fermilab’s Role in DESI Project
The Dark Energy Spectroscopic Instrument (DESI) project – which created the largest 3D map of galaxies to date – is managed by Berkeley Lab. According to a Fermilab article, Fermilab is providing specialty systems for collecting and analyzing the galactic light, including a corrector barrel, which plays a critical role in holding DESI’s six giant lenses in perfect alignment.
