The Cheltenham Science Festival took place over the course of the past week, and Jonathan was there to see some of the finest minds in science and technology come together to discuss a wide range of topics.

On this week's episode, Jonathan catches up with FameLab Ireland Champion Hayden Wilkinson ahead of his participation in the FameLab International finals.

He also sits down with Kit Chapman, author of 'Superheavy' to chat about how much the periodic table has changed almost 150 years on from its first publication & the incredible race to find new and previously unknown elements.

As always, Jonathan responds to all your tweets and texts.
