SCIENCE LESSON: “If anybody thought that the Cold War was over and the world was relaxing, that there was less need for scientists to get involved, they ought to think again,” arms-control expert Sidney Drell said during a February 5 talk at the Center for International Security and Cooperation. Drell, deputy director emeritus at the Stanford Linear Accelerator Center and Hoover Institution senior fellow, said the presence of high-level science advisers in the White House has been diminishing ever since Lyndon Johnson was in office, but the recent terrorist attacks make clear that their expertise—particularly in biology and information technology—is needed. “I think it’s important that we make [scientific advising] part of our lives.”
