A Meeting Of Minds In Philadelphia
The 150th gathering of the American Association for the Advancement of Science had a distinguished guest list: President Bill Clinton opened the event in Philadelphia last week with a call for strong antitobacco legislation. Also in attendance were Ian Wilmut, who cloned the famed sheep Dolly; U.S. Surgeon General Dr. David Satcher; and U.S. Supreme Court Justice Stephen G. Breyer, who discussed science in the courts. Here are some of the highlights.
