The US Energy Secretary Federico Peña has announced that he will resign at the end of June for personal reasons. The Department of Energy (DOE) runs some of the world's biggest physics laboratories, such as Los Alamos and Brookhaven, and supports the bulk of US research in particle, nuclear and plasma physics. Peña said that his successor's greatest challenge will be sorting out the problem of nuclear waste disposal. His deputy, Elizabeth Moler, is likely to replace him.
