Warm Bodies, Cool Muscles (IMAGE) Brown University Caption A new study shows that bats wing muscles operate at significantly lower temperatures than their bodies, particularly during flight. Understanding how bats get such high performance out of cold muscle could provide insights to human muscle performance in cold temperatures. Pictured is the fruit bat species Carollia perspicillata, which was used in the study.
