MIT makes move toward vehicles that morph

Picture a bird, effortlessly adjusting its wings to catch every current of air. Airplanes that could do the same would have many advantages over today’s flying machines, including increased fuel efficiency. Now MIT engineers report they may have found a way for structures — and materials — to move in this way, essentially morphing from one shape into another. The discovery could lead to an airplane that morphs on demand from the shape that is most energy efficient to
