Tiny hairs in the ear which detect sounds have been regenerated to reverse deafness for the first time, say US researchers in the journal Neuron. An injection of a drug led to the creation of new hairs in tests on mice. Normal hearing was not restored, rather the mice went from hearing nothing to detecting sounds such as a door slamming or traffic.
