November 12, 2026 — On November 2, DOE Under Secretary for Science Dario Gil visited the Kitt Peak National Observatory in Arizona, home of the Mayall 4-meter Telescope, which currently hosts the Dark Energy Spectroscopic Instrument (DESI) an international, Berkeley Lab-led experiment that has produced the largest 3D map of the universe to date. Researchers use the map to explore dark energy, which makes up about … Read More

November 11, 2026 — Nearly a mile underground in South Dakota, crews have started assembling large steel beams to form the outer structure of massive detector modules for DUNE. With the start of construction on its far detectors, the international Deep Underground Neutrino Experiment (DUNE) is one step closer to investigating some of the universes greatest mysteries including how the universe took shape after the Big … Read More

November 5, 2026 — The Simons Observatory in Chile, which houses four telescopes the Large Aperture Telescope (LAT) and three Small Aperture Telescopes (SATs) is now completely online and conducting science operations. Together, these four telescopes look out on the cosmos with tens of thousands of detectors to collect the most precise measurements of the universes oldest light – the cosmic microwave background … Read More

November 3, 2026 — In this new video from Berkeley Labs Physics Division, learn how Berkeley Lab researchers are leading three world-class experiments in the search for Dark Matter: the LUX-ZEPLIN Dark Matter Experiment, TESSERACT, and the CAL-Pathfinder Axion Detector. … Read More

November 3, 2026 — Participants engaged in hands-on activities with Berkeley Lab physicists to learn about dark matter and the experiments leading the way in its detection, including the Berkeley Lab-led LUX-ZEPLIN (LZ) TESSERACT, and CAL-Pathfinder dark matter experiments, which aim to observe dark matter interactions with earth-based detectors. … Read More

October 9, 2026 — Congratulations to Francis Halzen of the University of WisconsinMadison, who was awarded the 2026 Nobel Prize in Physics on Oct. 6, for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin. Berkeley Lab scientists and engineers played a significant role in the IceCube Neutrino Observatorys conception and construction, and … Read More

Division Director Nathalie … Read More

September 15, 2026 — Berkeley Labs Physics Division hosted the Fall 2026 Mu2e Collaboration Meeting on August 31 to September 4, 2026. Held triannually, this meeting convenes scientists and engineers from across the world to present recent progress on the Mu2e muon-to-electron-conversion experiment at Fermilab, and to coordinate short- and long-term plans for commissioning the detector and computing systems, detector … Read More

September 2, 2026 — A new analysis from the LUX-ZEPLIN (LZ) experiment has recorded a single particle interaction that researchers have great difficulty explaining with known background signals from normal matter. The result does not yet meet the statistical threshold required to claim a discovery, but is the most compelling hint of dark matter reported by the experiment to date. … Read More

August 22, 2026 — The LBNL Physics Division hosted its twentieth Physics in and Through Cosmology workshop for QuarkNet Leadership teachers and high school students. This one-week, in person workshop held the week of June 22nd, 2026, at Berkeley Lab. Seven physics teachers and 43 students participated. The Standard Model of particle physics, neutrinos, quantum physics, dark matter, dark energy, CMB, quantum … Read More
