A new study, led by a theoretical physicist at Berkeley Lab, suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.
Before DESI, the Dark Energy Spectroscopic Instrument, can begin its 5-year mission from an Arizona mountaintop to produce the largest 3D sky map yet, researchers first needed an even bigger 2D map of the universe.
The Department of Energy has announced that Susannah Tringe and Dan Kasen, two scientists at Lawrence Berkeley National Laboratory (Berkeley Lab), will receive the Ernest Orlando Lawrence Award, one of DOE’s highest honors. Additionally, former Berkeley Lab scientist M. Zahid Hasan was also named as one of the eight recipients.
Researchers from Berkeley Lab and Los Alamos National Laboratory have developed new methods for the large-scale production, purification, and use of the radioisotope cerium-134, which could serve as a PET imaging radioisotope for a highly targeted cancer treatment known as alpha-particle therapy.
The Daya Bay Reactor Neutrino Experiment collaboration – which made a precise measurement of an important neutrino property eight years ago, setting the stage for a new round of experiments and discoveries about these hard-to-study particles – has finished taking data. Though the experiment is formally shutting down, the collaboration will continue to analyze its complete dataset to improve upon the precision of findings based on earlier measurements.
Berkeley Lab has a long history of participating in neutrino experiments and discoveries in locations ranging from a site 1.3 miles deep at a nickel mine in Ontario, Canada, to an underground research site near a nuclear power complex northeast of Hong Kong, and a neutrino observatory buried in ice near the South Pole.
Surrounded by lead and also shielded by nearly a mile of rock from the natural bombardment of particles at the Earth’s surface, the CUORE experiment has amassed the largest dataset yet for a project of its kind, which is using solid crystals to detect a theorized event that would answer a big question about how matter won out over antimatter in our universe.
The American Association for the Advancement of Science, the world’s largest general scientific society, today announced that 489 of its members, among them nine scientists at Berkeley Lab, have been named Fellows. This lifetime honor, which follows a nomination and review process, recognizes scientists, engineers, and innovators for their distinguished achievements in research and other disciplines toward the advancement or applications of science.
Borrowing a page from high-energy physics and astronomy textbooks, a team of physicists and computer scientists at Berkeley Lab has successfully adapted and applied a common error-reduction technique to the field of quantum computing.
The effort to construct GRETA, a cutting-edge spherical array of high-purity germanium crystals that will measure gamma-ray signals to reveal new details about the structure and inner workings of atomic nuclei, has received key approvals needed to proceed toward full build-out.
