DOI: 10.1088/1361-6552/adea06
Abstract: This study investigates the curved rolling motion of a toy bowling pin by modelling it as a rigid two-wheel system with unequal radii. The pin’s asymmetrical shape—wider at the base and narrower at the top—causes… read more here.

DOI: 10.1103/physrevlett.134.198401
Abstract: The Drosophila larva, a soft-body animal, can bend its body and roll efficiently to escape danger. However, contrary to common belief, this rolling motion is not driven by the imbalance of gravity and ground reaction… read more here.
