Ytterbium's Broken Symmetry
July 22, 2009
Of the four fundamental interactions, the weak interaction has the shortest range of the fundamental forces and does some of the most peculiar things, like changing the flavor of quarks, governing the interactions of neutrinos and violating parity--nature's mirror symmetry. In ytterbium, researchers at Lawrence Berkeley National Laboratory's Nuclear Science Division and the University of California at Berkeley have measured the largest parity violations ever observed in an atom.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
