Collective Motion in Mosh Pits
Flocks of birds and schools of fish are two common examples of collective motion. Though herding behavior in animals is well recognized, humans exhibit their own set of emergent phenomena. For example, pedestrians walking down the sidewalk form lanes, and stadium crowds perform "The Wave".
Tsevi Beatus and Itai Cohen measure 5 millisecond reflex in fruit flies
Postdoctoral fellow Tsevi Beatus, working with Itai Cohen, associate professor of physics, and John Guckenheimer, professor of mathematics, have discovered that flies stabilize themselves during flight using a control reflex that’s among the fastest in the animal kingdom.
