Presented by Kat Arney, Meera Senthilingam


This week we find out the science of sound and music to discover how the human voice works and how in some cultures, music can play vital roles in society-such as enforce the law! We'll also be finding out the story behind the recent arenavirus outbreak in Southern Africa. Plus in question of the week we try to have a prty on the moon!
