Researchers have discovered a Lévy walk pattern of movement when living cells eat. When the food is transported within the cell by so-called endosomal active transport, it is the same mathematical pattern of movement that many animals follow when foraging for food. A Lévy walk or flight, named after a French mathematician Paul Lévy, is a mix of long trajectories and short random movements. Numerous short movements are made within a small area, and occasionally a long stride to a distant area, where the action is repeated. This particular motion pattern is observed in humans and animals.
