Mechanism helps explain the ear's exquisite sensitivity

The human ear, like those of other mammals, is so extraordinarily sensitive that it can detect sound-wave-induced vibrations of the eardrum that move by less than the width of an atom. Now, researchers at MIT have discovered ...

Implantable medical devices powered by the ear itself

Deep in the inner ear of mammals is a natural battery—a chamber filled with ions that produces an electrical potential to drive neural signals. In today's issue of the journal Nature Biotechnology, a team of researchers ...
