For the first time, scientists have edited the genes of cockroaches using CRISPR-Cas9, a technology that can target and change parts of an organism’s DNA, reports a new study. The breakthrough not only produced the first so-called “knockout cockroaches” in history, a term that refers to cockroaches with artificially inactivated genes, it could also dramatically simplify gene-editing in numerous other insects, opening up applications for pest control, evolutionary biology, and other entomological fields.
