Summary

ALBUQUERQUE, NEW MEXICO—Studies of the flight muscle of the dragonfly are helping physiologists understand what makes muscles strong. Results reported at the annual meeting of the Society for Integrative and Comparative Biology suggest that during development the muscle switches from making one form of a protein called troponin T to another form that boosts the muscle's sensitivity to the contraction-triggering effects of calcium ions.
