- Abstract:
- International treaties prohibit the development and use of biological weapons. Yet concerns about these weapons have endured and are now escalating. It is high time to take a hard look at technical and political developments and consider how the international security policy community should respond. A major source of the growing concern about future bioweapons threats stem from scientific and technical advances. Innovations in biotechnology are expanding the toolbox to modify genes and organisms at a staggering pace, making it easier to produce increasingly dangerous pathogens. Disease-causing organisms can now be modified to increase their virulence, expand their host range, increase their transmissibility, or enhance their resistance to therapeutic interventions.[1] Scientific advances are also making it theoretically possible to create entirely novel biological weapons,[2] by synthetically creating known or extinct pathogens or entirely new pathogens.[3] Scientists could potentially enlarge the target of bioweapons from the immune system to the nervous system,[4] genome, or microbiome,[5] or they could weaponize ‘gene drives’ that would rapidly and cheaply spread harmful genes through animal and plant populations.[6] Concurrent developments in other emerging technologies are also impacting potential future biological weapons threats. Developments in artificial intelligence and machine learning could speed up identification of harmful genes or DNA sequences. Artificial intelligence and machine learning could also potentially enable much more targeted biological weapons that would harm specific individuals or groups of individuals based on their genes, prior exposure to vaccines, or known vulnerabilities in their immune system.[7] Big Data and ‘cloud labs’ (completely robotized laboratories for hire) facilitate this process by enabling massively scaled-up experimentation and testing, significantly shortening ‘design-test-build’ timeframes and improving the likelihood of obtaining specificity or producing desired biological functionality.[8] Other developments provide new or easier ways to deliver pathogens or biological systems. Nanotechnology could potentially create aerosolized nanobots dispersing lethal synthetic microbes or chem-bio hybrids through the air,[9] or in vivo nanobots releasing damaging payloads inside human bodies.[10] Aerosol or spraying devices attached to swarms of small unmanned aerial vehicles, or drones, could be another potential means to disperse biological agents. Additive manufacturing, or 3D printing, could circumvent barriers imposed by national export control systems on controlled laboratory equipment or dispersal devices.
