Flying Jellyfish

I'm still enough of a science nerd that innovations like this fascinate me. Aerial propulsion is something that birds, bats, and insects make look easy, but coming up with a new concept for a machine that can do it is always difficult. It's true that airplanes today are technologically far beyond the Wright brothers' flyer, but the basic design in terms of what keeps them up is essentially the same. Helicopters are different, but helicopters also all use the same basic design. Having a machine emulate a bird is harder than it looks, because birds (and bats and insects) are basically constantly adjusting their flight, unlike an airplane which is much less flexible.

In any event, someone coming up with a new idea of how to fly is interesting in itself. Here's a link to the story from NewScientist and a video.
