cremmauriro.ml/map18.php Here, we recorded x-ray diffraction movies, at a rate of frames per second, simultaneously from the two antagonistic flight muscles of bumblebees during wing beat. Signals that occurred at the right timing for triggering each wing-beat stroke were resolved in both muscles.
The signals likely reflect stretch-induced myosin deformation, which would also enhance force in vertebrate muscles. The results suggest that insects use a refined preexisting force-enhancing mechanism for high-frequency wing beat, rather than developing a novel mechanism.

Abstract The high-frequency wing beat of higher-order insects is driven by self-sustained oscillations of constantly activated flight muscles.
Seen by more than 65 million people in 42 countries and in 22 languages around the globe, it is still breaking box-office records everywhere in its 28th year. Working Life Learning to lead.
