New Model Explains Ant Colony Bursts at Critical Threshold, Triggered by 1 Ant

Summary
A PRX Life study finds ant colonies enter a burst-capable state only after speed, density or interaction range crosses a critical threshold, letting one ant ignite nest-wide synchronized activity.
The model explains the switch through two conditions: colonies must be highly sensitive to a single ant’s movement, and that activity must spread faster than the colony’s slower cycle of activity and rest.
Ants in the simulations shift among 3 states—active, inactive and refractory—with the refractory phase halting endless cascades; when encounters are too rare or movement too slow, bursts die out instead of spreading.
The framework matches broad patterns seen in earlier observations but cannot predict exactly when a burst will start; it only identifies whether a colony is capable of producing synchronized bursts.
Experiments with living ants are now underway to test how close real colonies operate to that threshold and whether bursts help move information rapidly through the nest.
