Northwestern scientists put tiny particles in liquid under an electric field; they began moving together without touching, and the liquid carried the signals

Engineers at Northwestern University have made a fascinating discovery: tiny plastic spheres can synchronize their movements within a liquid environment. Remarkably, this phenomenon arises from fluid interactions rather than direct communication or contact. These findings could illuminate the dynamics of coordination seen in nature, such as in fireflies or heart cells. Researchers hope to leverage this synchronization to explore potential applications across various fields.
