Utah and Texas researchers have learned how quiet sounds are magnified by bundles of tiny, hair-like tubes atop "hair cells" in the ear: when the tubes dance back and forth, they act as "flexoelectric motors" that amplify sound mechanically. "We are reporting discovery of a new nanoscale motor in the ear," says Richard Rabbitt, professor and chair of bioengineering at the University of Utah.
