This week we jump into our genes to reveal how DNA previously thought to be 'junk' has an important role in our cells, as well as find out how stomach bacteria have enabled us to discover how our ancestors migrated across the world. We'll also be finding out about rice strains being grown in Benin that are resistant to toxic iron levels, plus, we lose our hair for Question of the Week!
