Scientists at the University of California, San Diego (UCSD) have engineered a new gene drive that allows for a higher degree of control and minimizes the risk of genetic changes that could lead to unintended ecological consequences.

The “split drive” system allows genetic parameters and strategies to either limit or extend the gene drive potential. According to Dr. Ethan Bier, senior author of the study, this tailored approach to gene drives could potentially enable the control of insect vectors and pests in diverse contexts.
