Pentagon research project called "Insect Allies." Funded by the Defense Advanced Research Projects Agency (DARPA), the project involves using gene-editing techniques like CRISPR to infect insects with modified viruses that could help make America's crops more resilient. If a cornfield were hit by an unexpected drought or suddenly exposed to a pathogen, for example, Insect Allies might deploy an army of aphids carrying a genetically modified virus to slow the corn plant's growth rate. According to the DARPA website, these "targeted therapies" could take effect in a single growing season, potentially protecting the American crop system from food security threats...
