Special Report: New Tools Join Old In Microbiological Research
Ricki Lewis | Apr 28, 1991 | 7 min read
Microbiological Research Author: RICKI LEWIS AND HOLLY AHERN, p.24 Microbiology has evolved from ancient art to savvy science. Yesterday's painstaking tasks of culturing and identifying microorganisms have been joined by rapid detection strategies and intricate genetic manipulations. Microbiologists may still streak specimens on agar plates and wait overnight for bacterial colonies to grow, as was done two centuries ago, but today they may also use spectrophotometers or chromatographs.

Polar Regions Offer Rich Opportunities For Research
Douglas Siegel-causey | Apr 26, 1998 | 7 min read
Polar science is receiving increased attention this spring with several new developments in the national and international arenas. At last month's meeting of the United States-Russian Joint Commission on Economics and Technological Cooperation, one of the major agenda items was Arctic sciences. This commission has met semiannually since it was initiated in 1993 by U.S. Vice President Al Gore and former Russian Prime Minister Viktor Chenomyrdin to establish new intergovernmental agreements for

Biological Terrorism

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
