ScienceNow: Under pressure from researchers, the U.S. Commerce Department has retreated from new export-control rules that would have made it harder for some foreign scientists to do research in the United States. Instead, the department has decided to appoint a committee of officials from government, industry, and academia to take a comprehensive look at policies aimed at keeping sensitive technologies from falling into the wrong hands. The decision allows universities to continue including foreign nationals in campus research without obtaining export licenses.
