Five Berkeley Lab Researchers are 2013 APS Fellows

This year’s recently announced American Physical Society (APS) Fellows includes five scientists from Berkeley Lab, two from the Materials Sciences Division and one each from the Accelerator and Fusion Research, Nuclear Science, and Engineering divisions. APS Fellows are elected by their peers for “exceptional contributions to the physics enterprise; e.g., outstanding physics research, important applications of physics, leadership in or service to physics, or significant contributions to physics education.”

Searching for Cosmic Accelerators Via IceCube

In our universe there are particle accelerators 40 million times more powerful than the Large Hadron Collider at CERN, but scientists don’t know what or where these cosmic accelerators are. New results reported from “IceCube,” the neutrino observatory buried at the South Pole, may show the way.

New results from IceCube, the neutrino observatory buried at the South Pole, may show the way to locating and identifying cosmic accelerators in our galaxy that are 40 million times more powerful than the Large Hadron Collider at CERN.

New Results from Daya Bay – Tracking the Disappearance of Ghostlike Neutrinos

New results about the oscillation of neutrinos – elusive, ghostlike particles that carry invaluable clues about the makeup of the early universe – have been announced by the Daya Bay Collaboration, an international experiment taking place outside of Hong Kong.

Flawed Diamonds Promise Sensory Perfection

By extending the coherence time of electron states to over half a second, a team of scientists from Berkeley Lab, UC Berkeley, and Harvard University has vastly improved the performance of one of the most potent possible sensors of magnetic fields on the nanoscale – a diamond defect no bigger than a pair of atoms, called a nitrogen vacancy (NV) center. The achievement is an important advance for nanoscale sensors and quantum computing.

How do You Know if You Ran Through a Wall?

Researchers from Canada, California, and Poland have devised a straightforward way to test an intriguing idea about the nature of dark energy and dark matter. A global array of atomic magnetometers – small laboratory devices that can sense minute changes in magnetic fields – could signal when Earth passes through fractures in space known as

In Memoriam: Stuart Freedman, Renowned Nuclear Physicist

Stuart Jay Freedman, a physicist in Berkeley Lab’s Nuclear Science Division and professor of physics at the University of California at Berkeley, died November 9, 2012, at the age of 68. Freedman was a world-renowned investigator of fundamental physical laws whose many accomplishments include unique contributions to the study of neutrinos and the weak interaction.

Advancing Underground Science at South Dakota’s Sanford Lab

On Wednesday, May 30, the Sanford Underground Research Facility officially opened its Davis Campus, almost a mile deep in the former Homestake gold mine in the Black Hills of South Dakota. The event brought over 60 visitors including officials from federal and state government, scientists from universities and national laboratories, and local and national media. Berkeley Lab is the U.S. Department of Energy’s lead institution for this marked advance in underground science.

Lying in Wait for WIMPs

The LUX Collaboration is searching for the leading candidates for unknown dark matter, weakly interacting massive particles, or WIMPs. Located in the Sanford Underground Research Facility in the Black Hills, LUX’s 350 kilograms of liquid xenon and low background make it the most sensitive dark matter detector yet, but with the proposed LUX ZEPLIN Berkeley Lab researchers want to increase that sensitivity by orders of magnitude.
