One warning came in black-and-white in 1993: A U.S. Congressional Office of Technology Assessment report projected that releasing 100 kilograms of aerosolized anthrax spores upwind of the U.S. capital could kill between 130,000 and 3 million people-a lethality at least matching that of a hydrogen bomb. Last year, a U.S. Justice Department exercise revealed that discharging pneumonic plague in Denver could create 3,700 or more cases, with an estimated 950 or more deaths within a week.1 Then, acco
Flow Cytometry: It's Not Just For Immunologists Anymore
James Kling | Jun 22, 1997 | 9 min read
A low-profile child of the '60s, flow cytometry didn't capture the imagination of most researchers until the early 1980s. The decade saw the birth of the AIDS epidemic, and as attention focused on HIV, researchers needed a method to accurately and reproducibly characterize immune cells. Flow cytometry was suddenly thrust into the spotlight.

Editor's Note: On May 2, the National Academy of Sciences announced the election of 60 new members and 15 foreign associates from nine countries in recognition of their distinguished and continuing achievements in original research. Nearly half of the new members are life scientists. In this article, The Scientist presents photographs of some of the new members and comments from a few of them on their careers and on past and current research. A full directory of NAS members can be found online a
