In this episode, which coincides with this year’s Dementia Action Week, we speak to Dr Richard Oakley, Head ...
Although we can’t see them with the naked eye, the Earth is populated by vast numbers of tiny living organisms such as bacteria, fungi and viruses. Collectively, these organisms are known as microbes, and they have existed on the planet for billions of years. But what role did they play in the origin of complex life, how have they stuck around for so long and how can they help us shape a healthier future for the planet? In this episode, we speak to science writer and author Peter Forbes about hi...
Be it a pair of wolves that mate for life, a pod of female dolphins that hunt together, or a large colony of honeybees all working together in a hive, the natural world is filled with relationships of all kinds. But some relationships run deeper than others, even to the extent that certain species literally make their homes inside the bodies of others. This is an example of a symbiotic relationship – a long-term bond that exists between organisms of different species. In this episode, we speak t...
The history of the Earth is littered with dramatic events that have shaped the planet itself and the lives of the human beings who live on it in profound ways. Be it floods, famine or disease pandemics. Human beings have so far survived. But what in modern times can we learn from these past catastrophes? In this episode, we speak to author Lizzie Wade about her latest book Apocalypse: How Catastrophe Transformed Our World and Can Forge New Futures. She tells us how even though Neanderthals died ...
It’s commonly believed that the arts and the sciences have little in common with each other.

In this episode we speak to Tom Kerss an aurora chaser, astronomer and author of the book Northern Lights: The definitive guide to auroras about the best way...
The ocean covers more than 70 per cent of our planet’s surface. Thanks to its ability to absorb the excess carbon and heat generated by climate change, its potential to generate clean energy and the bountiful source of food it provides to both humans and animals, there’s little doubt the ocean is vital for the continued survival of the human race and of the planet itself. But all is not well. Ocean temperatures are climbing, coastal water levels are rising, and extreme weather events are becomin...
Humans have been fermenting foods for millennia, due to the process’s ability to enhance the flavours of what we eat and preserve it for when times are lean.
