Each single hair bundle within the live zebrafish ear contains fascin 2b fused with green fluorescent protein. In this time coarse, the fascin 2b molecules migrate to other regions of the bundle within 220 seconds.

Finding holds promise for repairing damaged hearing. Hearing is made possible when hair bundles protruding from hair cells capture the energy of sound waves, converting them into electrical signals that stimulate the auditory nerve to the brain. The hair bundles are made up of stereocilia, which sway in unison with other stereocilia, and remain permanently with us throughout our lives...
