J.B. Stock, A.J. Ninfa, A.M. Stock, "Protein phosphorylation and regulation of adaptive responses in bacteria," Microbiological Reviews, 53:450-90, 1989. Jeff Stock (Princeton University, Princeton, N.J.): "Although research on signal transduction has traditionally focused on eukaryotic cells, prokaryotes also respond to environmental signals. Recent studies, reviewed in this article, show that a single bacterial cell such as Escherichia coli may have as many as 50 different receptor kinases a

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
