About The Cover

More women are going into science than ever before, but a ``glass ceiling'' often keeps them from making it to the very top of the career ladder. This invisible barrier—and some creative ways of breaking through it—are described in the special section Women in Science, pages 1363 through 1388. Also see the editorial by Bernadine Healy, director of the National Institutes of Health, on page 1333, and a bibliography of books on women in science, page 1449. [Illustration by Rob Colvin]
