Flies and heart pacemaker research. Illustration of a laser-controlled experiment being carried out on the heart of a fly at different stages of its development. The laser (blue beam) is used to trigger a light-sensitive protein that controls the rhythm of the heart. This research may eventually lead to less invasive pacemakers in humans.
