  • Why we should rethink our relationship with alcohol

    Why we should rethink our relationship with alcohol
    May 29 2025
    The shocking fact is that alcohol is responsible for around three times more deaths globally than any other drug combined, save for tobacco. However, many of us still consume it. So how have we reached this point, and why is alcohol consumption still so deeply ingrained in human culture? In this episode, we speak to Professor David Nutt about the history of alcohol use and the many and varied effects it has on our health, lives and wellbeing. He tells us exactly what alcohol does to our bodies and brains, why some of us find it so difficult to stop drinking once we’ve started, and why education is vital if we are to limit the damage alcohol causes to public health.

  • How humans may soon become an interplanetary species

    How humans may soon become an interplanetary species
    May 25 2025
    It’s now been more than 50 years since any human being has set foot on the Moon, but the ambition to do so again has been gathering pace over the last decade or so. But some scientists and researchers are looking further ahead and planning to establish a human presence on distant planets such as Mars. In this episode, we speak to physicist and director of the Foundation for Space Development Africa Dr Adriana Marais about her book Out of This World and Into the Next: Notes from a Physicist on Space Exploration. She tells us what plans to establish a Moon base in the coming years can teach us about living on other planets, how we’ll select the crew to take on this bold journey, and how the technology being developed can help us to live more economically and environmentally here on Earth.

  • The listening hacks that can transform your health

    The listening hacks that can transform your health
    May 22 2025
    Our everyday lives are filled with sounds of all kinds – birdsong, traffic noise, the music we choose to listen to or is played in shops and restaurants, the list is practically endless. But what impact are these sounds having on our individual health and wellbeing and the world at large? In this episode, we speak to author and founder of The Listening Society Julian Treasure about his latest book Sound Affects: How Sound Shapes Our Lives, Our Wellbeing and Our Planet. He tells us how hearing is the first sense we develop, how ambient sounds impact our health and wellbeing, and how listening more closely to what’s going on around us, rather than simply hearing, can enhance almost every aspect of our lives.

  • How new research is combatting Alzheimer’s disease

    How new research is combatting Alzheimer’s disease
    May 18 2025
    One in three people born today will develop dementia of some form in their lifetimes. Of these, around 60 per cent will suffer from Alzheimer’s disease, the most common form of dementia. Currently, there is no cure for this debilitating condition but by raising awareness we can help to reduce its impact until the many researchers working around the world develop more effective treatments. In this episode, which coincides with this year’s Dementia Action Week, we speak to Dr Richard Oakley, Head of Research at the Alzheimer’s Society. He tells us what happens in the brain as Alzheimer’s disease develops, points out some early warning signs to look out for and talks us through some of the latest breakthroughs that may one day help us beat dementia once and for all.

  • How microbes are vital for life on Earth, and may even help save the planet

    How microbes are vital for life on Earth, and may even help save the planet
    May 15 2025
    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 his latest book Thinking Small and Large: How Microbes Made and Can Save Our World. He tells us the role microbes played in the evolution of multicellular life, their deep importance to the world’s ecosystems and how they may help us to produce the food, fuel and materials of the future.

  • How climate change is disrupting nature’s ancient symbiotic relationships

    How climate change is disrupting nature’s ancient symbiotic relationships
    May 11 2025
    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 to science writer Sophie Pavelle about her new book To Have or to Hold: Nature’s Hidden Relationships. She tells us how far from being rare, symbiotic relationships occur practically everywhere in the natural world, how they come in a dizzying array of different forms, and how the fine balance underpinning these relationships that has formed over thousands of years is coming under threat from human activity and climate change.

  • How catastrophes have shaped the world as we know it

    How catastrophes have shaped the world as we know it
    May 8 2025
    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 out many years ago they still live on in human DNA, how ancient civilisations that once thrived fell but their culture persists to this day and how the story of the human race is far from finished.
