Baryon acoustic oscillations provides a “standard ruler” for the Universe, a way to measure the details of dark energy.

Gravitational lensing, which depends on Einstein’s Theory of General Relativity, directly tests its ability to predict the growth of large-scale structure.

A report from the National Academies of Science cites damage to human health from air pollution associated with electricity generation and motor vehicle transportation as one of the single biggest hidden costs of energy production

A symposium in Washington organized by the Office of High Energy Physics will break new ground in integrating research and development of many kinds of accelerators in many fields.

Warm dense matter exists in the cores of gas giant planets and the preliminary stages of nuclear fusion, among other inaccessible places. With an accelerator built at Berkeley Lab by physicists and engineers in the Heavy Ion Fusion Science Virtual National Laboratory, a collaboration of Berkeley Lab, Livermore, and Princeton, scientists will soon be able to study it in the laboratory.

Hyper-SAGE boosts remote MRI signals 10,000 times, making it possible to image molecular-sized clinical targets, including lung and other cancers.

After a quarter of a century in the Northwest, including 15 years as head of DOE’s Institute for Nuclear Theory, native Californian Wick Haxton returns to the Bay Area, with joint appointments in the Nuclear Science Division and UC Berkeley’s Department of Physics.

The ALICE experiment at CERN is the setting for a high-energy physics event that triggers world-wide havoc in the science-fiction novel Flashforward, by Robert J. Sawyer. The novel is the basis for a new ABC action-adventure series, “FlashForward.” Peter Jacobs of Berkeley Lab’s Nuclear Science Division, a member of the ALICE collaboration, talks about the real science at ALICE and how it compares to what’s described in the novel.

Berkeley Lab is partnering with Oakland Technical High School and El Cerrito High School in their Green Academies. Beginning this fall, students and their teachers will be able to take lab tours, hear talks by Berkeley Lab scientists and eventually, some will have eight-week summer internships.

Tomorrow’s free electron lasers will use superconducting linear accelerators to accelerate a million or more electron bunches a second. Key to high brightness and high repetition rates is the accelerator’s electron injector. Berkeley Lab scientists are building a revolutionary injector prototype of the kind the new generation of light sources will require.
