Thousands of the world's top science and engineering researchers, policymakers, educators, and journalists gathered in Chicago 11-16 February for the 2009 AAAS Annual Meeting. The meeting featured events and presentations from every discipline, many focused on the most urgent issues of our time. AAAS Annual Meeting News Blog editor Edward W. Lempinen, along with writers Benjamin Somers, Becky Ham, and others, provided extensive coverage. The blog served also as a guide to coverage from other points on the AAAS dial: the journal Science, the Science Podcast, and the Science Update radio show. And we sampled Annual Meeting news coverage from around the world.
