This week, we explore the latest in laser technology, including how a team in South Africa have developed a way to remotely seal cracks in industrial pipes and how lasers are being used to treat cancers in medicine. We also hear about a newly identified chemical that promotes the growth of brain cells and how a shrinking proton is changing the laws of physics! Plus, we investigate the development of the New World, in Question of the week!
