From asteroids to aliens - how space is threatening our planet Sep 25, 2025

Show notes

Is our planet under threat from the depths of space? In this episode, we talk to solar physicist Dr Ryan French. Normally, Ryan is busy unravelling the mysteries of our Sun, but today we’ll be delving into a slightly darker topic – the many risks posed to our delicate planet from space. In his recent book, "Space Hazards: Asteroids, solar flares and cosmic threats”, Ryan covers all the many dangers our planet faces from space rocks, the Sun and the farthest reaches of the Universe. We run through some of the most pressing threats and find out just how worried we should be.

Why we treat our pets and possessions like human beings Sep 21, 2025

Show notes

Many of us treat our pet dogs or cats with the same love and attention that with give to our human babies, some of us give our cars or other prized possessions human names and may even, at times, talk to them. This is known as anthropomorphism – the tendency within many of us to assign human qualities to non-human animals and even inanimate objects.

In this episode, we’re joined by Dr Justin Gregg to talk about his latest book, Human-ish – How Anthropomorphism Makes Us Smart, Weird and Delusional.

He tells us how we’ve bred our pets to look and behave in more and more human-like ways, the benefits we can all gain from attributing human-like qualities to inanimate objects such as cars or musicalminstruments, and how AI chatbots are expanding the phenomenon of anthropomorphism further than ever before.

How bats became one of the planet’s most successful animals Sep 18, 2025

Show notes

It’s a little-known fact that bats are one of the most successful animals on Earth, with almost 1,500 different species currently identified. Their agility in flight and prowess as hunters, wide-ranging diversity in size and behaviour and ability to adapt to almost any environment have allowed them to conquer almost every corner of the globe. But despite their success, many species of bats are now under threat.

In this episode, we’re joined by ecologist and neurobiologist Prof Yossi Yuval to talk about his latest book, The Genius Bat – Understanding our Most Mysterious Mammal.

He gives us a breakdown of bats’ sophisticated ability to ‘see’ the world using sound, tells us how despite their reputation as terrifying blood-thirsty predators, vampire bats have highly developed social networks and will even share their meals with other members of their roosts, and also explains how the loss of bats could have a huge effect on the ecosystems in which they live.

Why penguins are one of the planet’s most unique bird species Sep 14, 2025

Show notes

Thanks to their comical waddle-like way of walking, striking tuxedo-patterned plumage or graceful ability to seemingly ‘fly’ beneath the water, penguins are without doubt one of the planet’s most instantly recognisable animals. But the fact is that they are also one of its most endangered species of bird.

In this episode, we’re joined by Dr Peter Fretwell, lead scientist at the British Antarctic Survey, to talk about his latest book The Penguin Book of Penguins – An Expert’s Guide to the World’s Most Beloved Bird.

He tells us how, despite popular belief, penguins are found all over the globe, not just in Antarctica, why exactly they have such a comical way of walking and the actions we need to take if we want to save these charismatic birds from extinction.

Busting the biggest myths in neuroscience Sep 11, 2025

Show notes

Relatively speaking neuroscience and psychology are young fields of scientific research that only really got going over the last hundred years or so. However, during this time several stubborn myths have arisen that, zombie-like, just don’t seem to go away.

In this episode, we speak to neuroscientist, best-selling author and long-time BBC Science Focus contributor Dr Dean Burnett.

He tells us how much of our brain we really use, explains whether polygraphs can really tell if we’re lying, and explains the real difference between our left and right brains.

The positive tipping points that can help us solve the climate crisis Sep 07, 2025

Show notes

When it comes to climate change, we often think of tipping points as having a huge negative effect. Be it the loss of ice sheets in the Arctic, the deforestation of the Amazon rain forest or the alteration of ocean currents, scientists have identified several key systems on the Earth that will be impossible to reverse if they cross a critical threshold. But if we look at the situation from the opposite side, there are also several positive tipping points that, given the correct momentum, can potentially halt the crisis the planet is facing.

In this episode, we’re joined by Prof Tim Lenton, chair in Climate Change and Earth System Science at the University of Exeter, to talk about his latest book Positive Tipping Points – How to Fix the Climate Crisis.

He tells us how the pop group A-ha helped Norway to lead the way in the adoption of electric vehicles, how government mandates can act as powerful amplifiers to get us closer to these vital climate tipping points, and how each positive tipping point can feed into another to push us closer to a greener future.

How cats became one of our most-loved domestic pets Sep 04, 2025

Show notes

From Lewis Carrol’s mysterious grinning Cheshire Cat and Jim Davis’s lazy, lasagne-loving comic strip tabby Garfield to the depictions of big cats found in palaeolithic cave art and the ancient Egyptian’s practice of worshipping cat-like deities, it’s clear we humans have had a long-standing fascination with felines. But how did this obsession with these charismatic animals begin?

In this episode, we’re joined by Jerry D Moore, a professor of anthropology at California State University, Dominguez Hills, to talk about his latest book Cat Tales: A History – How We Learned to Live with Them…

He tells us how ancient cultures feared and revered the big cats they shared their land with thanks to their prowess as apex predators, how human’s development of agriculture and the storage of grain gave wild cats a reliable hunting ground in which to catch rodents, and how the domestic house cats of today may have chosen to live with us and much as we chose to live with them.

How the health of the oceans is vital for the health of the planet Aug 31, 2025

Show notes

Despite being a land-based species, the fact is that we humans live on a planet that is largely covered by oceans. The oceans play a key role in regulating the Earth’s climate and provide us with many of the resources essential for our continued survival – even down to the oxygen we breathe.

The sad truth is our oceans aren’t in good shape. But there is still hope. With directed effort we can all help to preserve this vital resource and improve the health of the planet and all who live on it.

In this episode, we catch up with oceanographer, environmentalist and grandson of the legendary ocean explorer and innovator Jacques Cousteau, Philippe Cousteau Jr.

He breaks down the huge importance the oceans have on the health of the planet, explains how taking positive environmental action can benefit us both culturally and economically and how educating the next generation is key to safeguarding the future of the planet.

The tiny molecules tackling the planet’s biggest challenges Aug 28, 2025

Show notes

In this episode, we’re joined by Professor Omar Yaghi – a pioneer of materials chemistry whose inventions are shaping the future of clean energy, clean air, and even clean water. He’s best known for creating metal–organic frameworks, or MOFs, and covalent organic frameworks, COFs – ultra-porous materials that can capture carbon, store hydrogen, and even pull drinking water out of desert air. His work has opened up an entirely new field of chemistry, and his breakthroughs are now being developed into technologies that could help us tackle some of the biggest challenges of the 21st century.

How to build a healthier, longer-living society Aug 24, 2025

Show notes

The most commonly held narrative states that we’re all ultimately responsible for our own health and wellbeing. While there’s undoubtedly truth in this idea, the bigger picture shows that the societies we live in and the policies shaped by our governments also play a huge role in our quality of life and longevity.

In this episode, we’re joined by Devi Sridhar, professor of global public health based at the University of Edinburgh, about her latest book, How Not to Die (Too Soon) – The Lies We’ve Been Sold and the Policies That Can Save Us.

She explains how the key to longevity begins with education, discusses the lessons we can learn from some of the world's longest-lived populations, and outlines the positive societal changes governments can implement to help us all live longer, healthier lives.
