Summary
The escalating political crossfire over alleged Chinese spying at U.S. nuclear weapons laboratories has produced its first scientific casualties. This week, officials at the Los Alamos National Laboratory in New Mexico said that new Department of Energy restrictions designed to prevent spying by foreign scientists have led to the departure of at least one highly regarded researcher, while several foreign-born scientists have turned down postdoctoral fellowships because of concerns about their working conditions. The new rules also have made it more difficult for scientists from "sensitive" nations, including China, India, and Russia, to obtain research funds, computing time, and visitation permits.
