As far back as Icarus's ill-fated aviation attempt, humans have looked to birds for inspiration in our airborne endeavors. But truly birdlike flight with flexible, feathered wings has long eluded us; for one thing, engineers have struggled to understand how birds control wing feathers. But two new studies could change that. Researchers recently designed and flew a robot with feathered wings that can change shape midflight like birds' do, giving it greater maneuverability than rigid drones.
