Could endangered species someday not be endangered at all, thanks to cloning? Robert Lanza, Betsy Dresser, and Philip Damiani address that subject in "Cloning Noah's Ark." If sheep, cattle, and lab mice can be cloned..."What About Rover and Fluffy?" As if that's not challenging enough, how about getting to Mars? "The Vasimr Rocket" could be just the ticket. The down-to-earth problem of fighting AIDS is most acute in Africa, where in some places the death toll is reminiscent of the plague. In "AIDS Drugs for Africa," Carol Ezzell examines the role drug companies are playing in getting pharmaceuticals to where they're needed. And, the personalities behind the creation of the atomic bomb: the disciplined Italian physicist Enrico Fermi and the brilliant but lackadaisical Leo Szilard. Writer William Lanouette calls them "The Odd Couple and the Bomb."
