This book examines how emergent trends in innovation and its governance are raising new and old questions about how to control technology. It develops a new framework for understanding how emergent fields of science and technology emerge as security concerns; and the key challenges these fields pose from a global security perspective. The study focuses on the politics which have surrounded the emergent field of Synthetic Biology, a field which has become emblematic of both the potentials and limits of more preemptive approaches to governance. This highly accessible work will be of interest to both scholars and practitioners working on the ethical responsibilities of innovators and the assessment of emergent technology as well as the global governance of weapons.
