Excerpt: WASHINGTON, D.C.—How much should scientists tell patients about the chemicals discovered in their bodies if they don't know what the levels mean for their health? Science's Erik Stokstad chats with Rachel Morello-Frosch of the University of California, Berkeley, about this and other issues in this short podcast. Morello-Frosch discussed her work during the "Reporting Chemical Exposures: Who Should Know?" press conference yesterday at the annual meeting of the American Association for the Advancement of Science (which publishes ScienceNOW).
