Using a novel form of gene therapy, scientists from Harvard Medical School and the Massachusetts General Hospital have managed to restore partial hearing and balance in mice born with a genetic condition that affects both.

The new model overcomes a long-standing barrier to accessing hair cells, the delicate sensors in the inner ear that capture sound and head movement and convert them to neural signals for hearing and balance. These cells have been notoriously difficult to treat with previous gene-delivery techniques.
