Insects have muscles that can execute one of the fastest movements: wings moved at an astonishing frequency of 1,000 Hz is one example. This means that they need quick access to oxygen for such fast burning. New imaging technologies could solve a physiological paradox in this equation: how their respiratory system, ... |
