Agricultural Research, or a New Bioweapon and Its Means

Agricultural genetic technologies typically achieve their agronomic aims by introducing laboratory-generated modifications into target species’ chromosomes. However, the speed and flexibility of this approach are limited, because modified chromosomes must be vertically inherited from one generation to the next. In an effort to remove this limitation, an ongoing research program funded by the U.S. Defense Advanced Research Projects Agency (DARPA) aims to disperse infectious genetically modified viruses that have been engineered to edit crop chromosomes directly in fields.
