In order to reduce these reflections and maximize the transfer of sound energy from the air filled environment to the fluid filled inner ear, land animals evolved external ears as sound collectors and ...

By labeling stem cells with a genetic 'barcode', they have been able to follow the cells' developmental journey and discover how the inner ear is formed in mice. The discovery could provide ...
