Studying metabolism in flying animals poses challenges due to the complexity of monitoring them in flight. However, vampire ...

Researchers have discovered an infrared-sensing protein channel that allows vampire bats to identify the hottest part of the animal—veins close to the skin’s surface that carry 38 degree-Celsius (100° ...

Based on the vampire bat’s diet, Welch and his team hypothesized that the mammals would use the amino acids from blood to fuel their running and flying. To test the hypothesis, the scientists ...

Vampire bats, for example, feed only on blood ... Tsetse flies and female mosquitoes fuel their energetically costly flying activities by directly burning the amino acids that make up the proteins ...
