During flight, insects beat their wings hundreds of times per second, faster than would be possible if their flight muscles worked by contraction, like vertebrate muscles do. How they do this is a matter of some debate, but new data from an x-ray scattering study suggest that insect flight muscle activation relies on a mechanism that is shared with vertebrate muscle.
