Particles synchronize oscillations with their neighbors (VIDEO)
Caption
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.
