Biological weapons have been around since medieval warriors hurled plague-ridden corpses over city walls to destroy their populations. Today what was once called "germ warfare" is even more threatening because of the ability to genetically alter pathogens. Recent events in the Persian Gulf and the United States have riveted attention on the "weaponization" of bacteria, viruses, and toxins.
