What do you do when you're under attack? Call for help, naturally. Unfortunately, if you're an ear of corn, and you're being attacked by parasitic beetle larvae, you have nothing to call for help with. Until now.
Scientists at the University of Missouri have genetically modified corn to release a chemical distress signal when under attack from beetle larvae. The chemical 911 call attracts droves of parastitic roundworms that naturally attack the larvae. Within three days of receiving the distress signal, the worms had killed them all.
