Abstraction: Insect swarms exhibit viscoelastic material properties with adaptive damping

Key points:

Ouellette (Stanford) et al. applied materials science methods to flying midge swarms — probed by oscillating a reference marker and measuring wave propagation through swarm layers
Swarms behave as viscoelastic materials: both elastic (spring-like) and viscous (liquid-like) properties
Viscosity dominates over elasticity, producing strong damping of external perturbations — swarm suppresses rather than amplifies disturbances
Damping may have biological relevance: keeping the swarm stable in place enables females to locate it for mating
Contrast with most collective behavior research, which focuses on signal amplification (e.g., predator-avoidance information spreading like a rumor through a flock)
Potential applications: tuning drone/robot swarm behavior and understanding information damping in social networks
