Mosquito killer drone: A palm-sized AI micro-drone has autonomously detected, tracked and intercepted a flying moth in mid-air, marking a significant engineering milestone. The technology could one day help target disease-carrying mosquitoes without relying on chemical insecticides. Instead of conventional cameras, the drone uses ultrasonic sonar and analyses insects' wingbeat signatures to detect, identify and track its targets.

Think of it like the Roomba of Death for planet Earth’s deadliest—and most annoying—animal.

A palm-sized AI drone weighing just 40 grams has achieved an engineering first by autonomously hunting and killing a flying insect in mid-air, paving the way for a new approach to…
