X-Ray Video Reveals How Bats Power Flight

Novel X-ray video of fruit bats mid-flight reveals a remarkably detailed look at the muscular and skeletal structure required for the mammals to take flight..

Using XROMM (X-ray Reconstruction of Moving Morphology) technology, a team of scientists led by Brown University's Nicolai Konow was able to better understand how bats manage to be the only mammal capable of sustained flight by capturing three-dimensional images of bone structure and movement patterns.
