Scientists at Brookhaven Lab, in collaboration with colleagues at Cornell University, Tokyo University, the University of California, Berkeley, and the University of Colorado, have uncovered the first experimental evidence for why the transition temperature of high-temperature superconductors — the temperature at which these materials carry electrical current with no resistance — cannot simply be elevated by increasing the electrons’ binding energy.

(University of California - Berkeley) UC Berkeley physicist Richard A. Muller has transformed his popular course, "Physics for Future Presidents," into a popular book of the same name, providing a tutorial in the physics of nuclear weapons, nuclear power, terrorism and global warming essential for anyone aspiring to the Oval Office.

His intent: to teach enough physics for a president to weigh the often partisan assessments of advisors, and to explain his or her reasoning to the public.

(University of California - Berkeley) UC Berkeley scientists have for the first time engineered 3-D bulk materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered computers, and, to the delight of science-fiction and fantasy buffs, cloaking devices that could render objects invisible to the human eye.

(University of California - Berkeley) A strange metal brew lies buried deep within giant gaseous planets such as Jupiter and Saturn, according to a new study by researchers at the University of California, Berkeley, and in London.

The study demonstrates that metallic helium is less rare than was previously thought, and is produced under the kinds of conditions present at the centers of giant gaseous planets such as Jupiter and Saturn, mixing with metal hydrogen to form a liquid metal alloy.

(University of California - Berkeley) Scientists at the University of California, Berkeley, have devised a way to squeeze light into tighter spaces than ever thought possible, potentially opening doors to new technology in the fields of optical communications, miniature lasers and optical computers.

(University of California - Berkeley) When UC Berkeley bioengineers tweaked how adult stem cells reacted to biochemical signals regulating cell division, they gave muscle in old mice a shot of youthful vigor.

The research sets the path for research on new treatments for age-related degenerative conditions, including muscle atrophy and Alzheimer's disease.
