A nanosized probe can mimic sound waves by tickling microscopic hairlike projections on inner ear cells (Nano Lett., DOI: 10.1021/nl3036349). The device could help researchers understand how the cells turn sound into electrical signals the brain can interpret, the probe’s developers say.

Sound vibrations perturb bundles of . . .
