In a new study, Northwestern engineers discovered that groups of tiny particles suspended in liquid oscillate together, keeping time as though they somehow sense one another's motion. The team used a computer simulation to model this behavior. They color-coded each particle, based on its position within its own oscillation cycle. Entire clusters lit up in matching hues, revealing groups of particles behaving like a single, coordinated unit.
From fireflies that blink in unison to heart cells that beat together, many living systems rely on coordinated timing without a central leader. The simulation's results could help explain how complex, collective behavior emerges without communication or signaling.
