Ants: Jam-free traffic champions
(PHYSorg.com Biology)

Whether they occur on holiday routes or the daily commute, traffic jams affect cars as well as pedestrians. Scientists at the Research Center on Animal Cognition (CNRS/Université Toulouse III-Paul Sabatier) and the University of Arizona (United States) have demonstrated that ant colonies, however, are spared these problems and circulate easily, even in the event of extremely dense traffic, thus ensuring consistent efficiency in their foraging. These findings appear in the 22 October 2019 edition of eLife.
