NASA has tested a new shape-shifting wing technology, which integrates the control surfaces into the wing itself.
NASA's green aviation project is one step closer to developing technology that could make future airliners quieter and more fuel-efficient with the successful flight test of a wing surface that can change shape in flight. This past summer researchers replaced an airplane’s conventional aluminum flaps with advanced, shape-changing assemblies that form seamless bendable and twistable surfaces.
Basically, instead of the normal, segmented control surfaces we're all used to, this is a long twistable surface. The downside is difficult engineering and production cost. The upside is less space taken up (more fuel in the wing) and improved aerodynamics. The aerodynamic gains lead to less cost and is better for the environment (if that's your kind of thing).
I found a YouTube Promotional video from the company actually producing the wings. I'd love to see a video of the actual tests if anyone can find one.

I am all for higher efficiency and the resulting fuel savings/lower emissions. The complex design doesn't concern me...too much. The question I have is one of safety. I fully realize that cost is going the be the biggest factor in this technology but the benefit of fuel savings can only be realized when the craft remains in service for an extended time. The tech might very well be able to save fuel but if it is found to have serious safety problems (most likely found after it is deployed to commercial aircraft in mass) there will be no benefit when those craft are grounded.
