Nanophobia

Does matter become more toxic when it's shrunk? Some European greens seem to think so, reports Noah Shachtman in Wired, and would "like to see a moratorium on the development of nanoparticles until there are clear and agreed-upon processes for assuring safety, and that take into (account) nanotechnology's impact on society, democracy, culture and the environment."

Says the head of Northwestern U's Institute for Nanotechnology, "Saying you want to ban nanotechnology is like saying 'I want to ban all science.'" Actually, some greens in Europe—and here—may see it that way, too.
