Episode 324 The legendary primatologist Jane Goodall died last week aged 91, leaving behind a remarkable legacy. Her work studying tool use in chimpanzees completely reshaped the way we view animal intelligence. Fiercely protective of the natural world, she was also responsible for a huge amount of advocacy during her life. Primatologist Alejandra Pascual-Garrido worked directly with Jane and shares the story of her life and work. Will the universe end with a bang, or a quiet whimper? Katie Mack is a cosmologist, science communicator and best-selling author of The End of Everything. She explores why she’s fascinated by how the universe might end, the most likely scenarios for how it happens and why it’s an exciting time for both physics and cosmology. She also offers her thoughts on the recently announced Nobel Prize in Physics - and teases her upcoming book How To Build A Universe. Older fathers may have a bigger impact on the health of their offspring than we realised. We know that sperm accumulates mutations as men age, but a study sheds new light on the risks. Men aged 70 are twice as likely to have children with serious genetic disorders. And it’s all to do with “selfish sperm”. Chapters: (00:51) Jane Goodall’s legacy (20:52) Kate Mack on the end of the universe (38:47) Selfish sperm Hosted by Rowan Hooper and Penny Sarchet, with guests Alejandra Pascual-Garrido, Katie Mack and Michael Le Page.

  • On this week's show we hear how Jane Goodall changed the world.

  • We've lost this connection to our heart to love, compassion, to nature.

  • And we speak with a primatologist who studies tool use in chimps in Gombe and worked with Jane Goodall.

  • She starts to realise that they have personalities and she's able to actually bring humanity closer to the natural world.

  • We're also welcoming physicist Katie Mack to the pod and we're going to be discussing the small matter of the end of the universe.

  • Spoiler, it's not happening tomorrow.

  • We also hear about a new theory as to why older men are more likely to pass on disease-causing mutations to their children.

  • What does it mean for older men who might be considering starting...

  • Well, I'm...

  • I'm just excluding myself from this.

  • Asking for a friend.

  • This episode is sponsored by Yakult, the gut experts for over 90 years.

  • I'm Dr Penny Sarge and I'm Dr Roan Hooper.

  • Welcome to the world, the universe and us.

  • We're going to start with Jane Goodall.

  • When she died last week, aged 91, there was a huge response from around the world.

  • And that's a sign not just of how much she was respected and admired, but also what she achieved.

  • She changed the world, didn't she?

  • Firstly, with her discovery of tool use in chimps, amazing discovery.

  • And then again, with her conservation advocacy around the world.
