Michael Levi, senior fellow on energy and the environment at the Council on Foreign Relations, offers a nice bit of advice for vetting the quality of talking heads called in to discuss the earthquake, tsunami, and nuclear crisis in Japan. Short version: Be skeptical of policy analysts who want to school you on physics.
He also suggests a couple of good, reliable sources of information, including David Lochbaum with the Union of Concerned Scientists; Olli Heinonen, formerly of the IAEA and now at Harvard, and the industry site I suggested yesterday, World Nuclear News.
I'd also add to that: Cristine Russell, who has been linking to some great articles on her Twitter feed and is putting together a list of who is getting this story right, and who's not; and New Scientist's ongoing coverage as part of their Short Sharp Science blog.
