This new composite behaves in a whole new way when you turn on the lights. It wiggles! The scientists from the University of Twene's MESA+ shared a report on their new nanoswitch in this week's Nature Chemistry .

The report marks the first time scientists have manipulated molecular rearrangement in such a way it produces a microscopic movement visible to the naked eye.

When the liquid-crystalline polymer is exposed to certain frequency UV lights, it causes the spring to perform all sorts of nifty contortions. The team was able to program their spiral ribbons to expand, contract, or even do both.
