Baltimore—This week, within a few short blocks of Baltimore's baseball stadium, U.S. Vice President Al Gore came out swinging in his speech at the Annual Meeting and Science Innovation Exposition of the American Association for the Advancement of Science. Some meeting highlights: Gore had choice words about political opponents and their support of science; Congressman Robert Walker, chair of the House Science Committee, had choice words for scientists about their unwillingness to state scientific priorities; and primate researchers spoke on the origin of moral choice. Later meeting sessions will be covered next week. (Full text of Gore's speech is available at http://www.aaas.org/spp/dspp/rd/rdwwwpg.htm)
