Quentin Cooper reports from the Edinburgh International Science Festival on the latest discoveries and their implications.
He hears (quite literally) how engineers can now design the acoustic of a building and re-create a 3-dimensional soundscape within it.
He explores the progress that has been made towards creating artificial life and the ethical questions it raises.
And he goes to an innovative Scottish research company to shake a bionic hand - and the flesh and blood hand of its inventor.
Plus, as the judges approach their final decision next week, we hear more Shortlisted entries for 'So You Want To Be A Scientist'.
