• The Discovery That Changed Astrophysics with Prof. Dame Jocelyn Bell Burnell (455)

  In this episode, I'm joined by the legendary Dame Susan Jocelyn Bell Burnell - the pioneering astrophysicist who discovered pulsars, launching an entirely new field of astrophysics. She began her PhD searching for quasars, but soon noticed a strange, repetitive signal appearing night after night - so peculiar she jokingly labelled it LGM ("Little Green Men"). That signal would become one of the most important astronomical discoveries of the century, though the credit and Nobel Prize were controversially awarded to her supervisor. Dr Bell Burnell also shares why she donated $4.3 million of her own prize money to support underrepresented researchers in physics, especially women and girls, and the work she's doing to make the field more inclusive. We dive into her views on religion, her life in science since that landmark discovery, and her mission to help more young women pursue careers in physics.

• Sunscreen Safety in Australia with John Staton (454)

  This week I'm joined by John Staton, one of Australia's leading sunscreen-testing experts, to unpack the big headlines surrounding sunscreen safety. A recent Choice report revealed that 16 out of the 20 tested sunscreen products failed to meet their advertised SPF rating by a significant figure. John helps us to understand what is really going on. He breaks down how sunscreens actually work and the science behind SPF testing and why so many products fell short.

• What are Time Crystals? with Prof. Geraint Lewis (453)

  In this episode, friend of the show and astrophysicist Professor Geraint Lewis returns to help me wrap my head around one of the strangest ideas in modern physics: Time Crystals. After stumbling across a Nature article that left my brain pleasantly scrambled, I called up Geraint for a deep-dive into what time crystals are and why physicists are so excited about them. We explore why Time Crystals don't have real-world applications yet, but how they could open entirely new frontiers in future technology.
