Restaurant menus have had to be wiped and rewritten across the south-west, but what else has changed? Tom Heap and Helen Czerski ask why octopus have such a hold on our imagination and the science world, why the octopus has moved north and what its journey can tell us about the changing oceans.

Joining Tom and Helen are the writer Sy Montgomery, marine biologist Dr Keith Hiscock MBE and octopus neuroscientist Dr Amy Courtney of the Marine Biological Association.

All In This Together

Friday, September 4, 2026 • Duration 52:45

Helen Czerski and Tom Heap ask if nature is really red in tooth and claw. Is life all about survival of the fittest or are we all working together on a changing planet?

They're joined by Rowan Hooper, author of Togetherness, lichen expert April Windle and Isabel Hardman, assistant editor of the Spectator magazine and author of The Natural Health Service: How Nature Can Mend Your Mind.

Together they discuss the plants and insects that rely on deals with other species to keep themselves healthy, from fungus-farming ants to the Wood Wide Web that connects most living plants. April shows Helen the wondrous lichens of Hyde Park and Rowan discovers the orchids studied by Charles Darwin at his home in Kent.

Drawing Our Future Homes

Friday, August 14, 2026 • Duration 52:14

Who's the hero that will protect us from the impact of extreme heat, rain and whatever else climate change might throw at us in future? Forget someone in a cape, maybe it's the person quietly sketching buildings on a bit of paper.

Architects shape the buildings we live in and rely on - can they change the way they work to make sure that our homes are smart enough to outpace the challenges of climate change? And can they lead the way in cleaning up the impact of the building industry? Or is the challenge just too great?

We find out with the help of:

- Isabel Allen, editor of Architecture Today - Barnabas Calder, reader in architecture at the University of Liverpool - Jay Morton, director of Bell Phillips Architects and incoming President Elect of RIBA

With thanks to Jess Hrivnak, and Melissa Mean and Jasmine Tippett from WeCanMake.

The Sound of Water

Saturday, June 27, 2026 • Duration 52:31

Helen Czerski and Tom Heap discover how new technology lets us listen in to the extraordinary sounds of the planet's waterways. From the deepest ocean to the tributaries, rivers and streams, this is an exploration of the sound made under water by animals, humans, and yes even plants. From the snapping of shrimp to the bark of a John Dory, Tom and Helen ask how sound travels through water, how important it is and what is known about the purpose of these sounds. They also ask what impact human activity is having on the watery soundscapes and their inhabitants. Joining Tom and Helen are Marine Biologist Steve Simpson, Former Submariner Bob Mansergh, Principle Scientist Rosalyn Seddon and Eco-Acoustician Jack Greenhalgh.
