Recent advances in disciplines such as biotechnology, nanotechnology, and neuropharmacology entail a "dual-use dilemma" because they promise benefits for human health and welfare yet pose the risk of misuse for hostile purposes. The emerging field of synthetic genomics, for example, can produce custom DNA molecules for life-saving drugs but also makes possible the creation of deadly viral agents for biological warfare or terrorism. The challenge for policymakers is to prevent the misuse of these new technologies without forgoing their benefits . Innovation, Dual Use, and Security...
