When fruit flies are attacked, they react like fighter planes, thrusting their bodies in a sharply slanted curve in order to avoid the attacker. This is a finding from a study conducted at the University of Washington using high-speed cameras. The results of the study, which was financed in part by the United States Army, were recently published in Science. The list of authors contains two names from TU Delft: Johan Melis (student) and Florian Muijres (alumnus). Fruit flies can change their course in less than 1/100 of a second.
