The beating of a fruit fly's "head-heart" (VIDEO)
Caption
Biologists at the University of Iowa have discovered a "heart" in the fruit fly’s head functions much like a human’s: Its rhythmic pulses are automatically generated by a tiny muscle that runs through the middle of the brain, from front to back of the fly’s head. The biologists filmed the head-heart in action in a living fly.
