Gene drives thwarted by emergence of resistant organisms

By studying the insects under more-natural conditions, scientists hope to better understand how to eradicate them — and malaria — using an emerging genetic-engineering technology called gene drives. The technique can quickly disseminate genetic modifications in wild populations through an organism’s offspring, prompting some activists to call for it to be shelved. Yet gene drives might not be as effective as activists think. Recent research has identified a major hurdle to using them to eliminate diseases and vanquish invasive pests: evolution.
