Dual-use research and the H5N1 bird flu : is restricting publication the solution to biosecurity issues?

Recent studies altering the host range of the H5N1 bird flu virus have refueled intense debatesover the potential misuse of academic life science research. To curtail the bioterrorism threat,it has been suggested that dissemination of the research results and methodology should berestricted. However, doubts have been raised over the suitability and effectiveness of thismeasure. Using the H5N1 studies as an example, this paper summarizes the main argumentsof the debate. Particular attention is paid to the issue of the tacit knowledge required to replicatepublished life science research results, which has so far received limited attention. Taking intoaccount the importance of tacit knowledge for life science research, it is argued that preventingpublication of the methodology does not decrease the threat of bioterrorism.
