To move wings at full speed, flexible miosina

Researchers from the Illinois Institute of Technology (USA) explain how insects move their wings so fast. It has been proven that the response is in the myosine and actin proteins, especially in myosine.
They already knew that the relationship between these proteins is contraction and relaxation of the wing muscle. The question is that such a rapid movement cannot be controlled by nerve impulses. And they discover that miosina, like the docks, stores elastic energy in each contraction and releases it in the next fin.
The discovery is very important, but the technique used is also no joke, since they have followed the activity of the miosina with instant photographs, synchronizing the X-rays with the movement of the wings of a fly. To do this, they have tied a fly and made him believe that he is flying with wind and light games.
