Preliminary quantification of freely exploring Atta insularis
  In this paper, we study the "free exploration" of individual ants of the species Atta insularis, i.e., their motion on a featureless flat, horizontal surface. Two basic preliminary results emerge from our work (a) the free exploration is super-diffusive and (b) ants tend to turn more frequently to the left than to the right -so we call them "let-handed"-. More statistics is needed, however, to confirm those findings.
