Drawing from the physics of self-propelled particles, the authors introduce a macroscopic model to describe their experiments on ants’ cooperative transport. They connected this to previous coupled-carrier models, bridging the gap from micro to macro scales.

This study expands the odd-elastic description of microswimmers to a nonlinear regime and provides a unified framework for studying non-local, non-reciprocal interactions of an elastic material in a viscous fluid, like biological flagellar motion.

In this study, resource foraging is analyzed using the framework of “Semantic Information theory” predicting a sharp transition in the forager’s expected lifetime as correlations with the environment are scrambled.

This study presents a model of cell motility that explains the initiation of cell motion by a symmetry-breaking instability and reveals that complex cell behaviors - from motility to shape selection - are governed by dynamic activities at the cell edge.
