Researchers from Harvard University and the University at Buffalo have uncovered a surprising ability in rats: the power to manipulate matter without touching it. These rodents use high-frequency sound waves, or ultrasonic vocalisations (USVs), to move microscopic particles and enhance their sensory perception.

Rats emit these high-pitched sounds, which range from 22 kHz to 80 kHz—far beyond human hearing. These vocalisations create air vibrations that can displace tiny particles, helping rats detect pheromones more efficiently. This ability not only aids in communication but also boosts their olfactory sensitivity, giving them an advantage in detecting smells related to territory, reproduction, and survival.
This discovery challenges traditional ideas about animal behaviour and could inspire innovations in fields like medical technology and sensory enhancement. If rats can manipulate particles with sound, the potential applications for humans could be revolutionary.
