Have you ever wondered how humans came about the concept of ‘measuring’ things? How did Ancient Egyptians use giant rulers to predict the harvest in coming months? James Vincent is the author of ‘Beyond Measure: The Hidden History of Measurement from Cubits to Quantum Constants’ and he joins me this week to talk about how this concept shapes the way we see the world.
I'm also joined by Dr Lara Dungan and Dr Shane Bergin for this week's Newsround discussing intrauterine surgery, blood tests to check sleep, a new organelle and how body odour could be the antidote to social anxiety.
