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 airplaneās 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.

In many planes, an excessive share of the in-cabin noise is actually from the HVAC.

Oh my, don't get me started on those overly loud recirc fans :) Fortunately, more modern airliners have mostly eliminated a large part of it. Recently I flew in a A380 and I gotta say, it *is* noticeably quieter than the 747-400 I flew in on the outbound leg.
