NYU, NJIT Model 1 Ant Triggering Colony-Wide Bursts in 3-State Phase Shift

Summary
A new NYU-NJIT study says synchronized ant-colony bursts can begin with a single “first mover” whose activation triggers a rapid colony-wide cascade.
The model explains those waves as a balance between two forces: how quickly one active ant excites nestmates and how completely the colony returns to rest before the next burst.
Three states — active, inactive and refractory — produced a phase transition in simulations, with colonies abruptly shifting from scattered motion to synchronized activity.
High-speed interactions were central: information spread through moving ants faster than a burst lasted, letting temporary contacts relay behavior across the nest almost instantly.
The researchers say the mechanism could generalize to neurons, flocking animals and robot swarms, though future experiments must test whether real colonies sit near the predicted synchronization threshold.
