Two events last week are prompting a public debate about whether unclassified research that might conceivably help bioterrorists should be openly published. A congressional resolution called on journals, scientists, and funding agencies to take more care about releasing such information, and, separately, the American Society for Microbiology sent a letter to the National Academy of Sciences 22 July requesting a meeting of biomedical publishers to discuss whether and how to publish research results that might be co-opted by terrorists.
