Yale Researchers Find Key 'Conductor' of Nature's Synchronicity Synchronicity in nature is seen in beating hearts, the flashing of fireflies' lights, the ebb and flow of infectious disease - and the simultaneous rise and fall of populations across vast reaches of space. While scientists have identified some factors that account for this melodic phenomenon, they have yet to sort out the relative contribution each plays in this finely tuned orchestra. Now researchers at Yale University and the University of Calgary report in the July 22 issue of Nature's advanced online publication that predator-prey interactions are the "conductors" of synchronicity in living organisms.
