Seeds Germinate to Rain Sound

MIT experiments show that rice seeds exposed to the vibrations produced by falling raindrops germinate substantially faster (up to ~37% quicker) than identical seeds not exposed to those vibrations. The team recorded the acoustic signature of drops with a hydrophone and simulated falling water in tubs, producing a measurable acceleration of germination across thousands of seeds. — If generalizable, the finding implies that acoustic/vibrational cues are a biological trigger for germination, with consequences for farming practices, seed‑treatment technologies, ecological timing under changing rainfall patterns, and the potential vulnerability of plants to acoustic pollution.
