Dual-use research of concern—often referred to by its ugly acronym, DURC—is another one of those moronic concepts to have entered the disarmament / arms control discourse as a diversion from real disarmament questions. Of concern to whom? Who defines the dual-use characteristics of research? Who defines the threat? And why the heck should we be scared again of any new development? Anyway, the term is also tautological: Is there dual-use research not of concern?
The term arose in the biological field: genetic manipulations of pathogens to better understand possible mutations might increase infectivity among humans. The risk of escape from laboratories or laboratory accidents drive the concerns about this type of research. Initially the threat was presented as one of catastrophic terrorism. Now the debate has abated somewhat, but global health concerns continue to animate discussions. Meanwhile, the DURC label has stuck. So questions animating debates under the banner of biological weapons control are whether research can be published in full or whether scientists should apply for an export license to have their results printed in overseas scientific journals.
