Lots of us will have at some points in our lives woken up feeling groggy after getting a poor night’s sleep. But what causes us to have trouble sleeping, what effect does it have on our health and what can we do about it?
In this episode, we catch up Prof Matt Jones, a neuroscientist based at the University of Bristol.
He tells us how our sleep needs vary across our lifetimes, how not getting enough sleep can affect our ability to think straight and form memories, and why a lack of sleep can leave so many of us feeling cranky and impulsive.

Understanding who we are and where we came from is one of the most fascinating questions in science. But it’s also one of the most difficult to answer. Putting all of the pieces together requires research across several different disciplines such as genetics, anthropology and medicine.
In this episode, we catch up with Professor of Human Genetics and Evolution at College de France in Paris Lluis Quintana-Murci to talk about his latest book Human Peoples: On the Genetic Traces of Human Evolution Migration and Adaptation.
He tells us how the characteristics of different human populations have been shaped by the environments they live in, how our genes can protect us against disease and what we learn can from all of this about our future health and wellbeing.

Research over the past few decades has proven that getting a good night’s sleep is essential for our health and wellbeing. But sometimes strange things can happen in our brains while we’re asleep.
In this episode, we catch up with Dr Dan Denis, a sleep researcher and lecturer at the University of York’s department of psychology.
He tells us what happens in our brains and bodies when we dream, why some of us are prone to sleepwalking and even sleep eating, and talks about the strange phenomenon of lucid dreaming.

Since its launch on Christmas Day 2021, the James Webb Space Telescope has delivered some of the most stunning images of space we’ve ever seen, peering deeper into the cosmos than ever before. But as awe-inspiring as these images are, data about the history of the Universe being collected by the telescope are perhaps even more mind-blowing.
In this episode, we catch up with Sky at Night Presenter Dr Maggie Aderin-Pocock to talk about her new book Webb’s Universe: The Space Telescope Images that Reveal our Cosmic History.
She tells us how the telescope is shedding new light on what we know about the birth of stars and galaxies, how it’s teaching us more about the structure and atmospheres of distant exoplanets and what she’s most excited about it discovering in the future.

Our bodies have in-built clocks that allow us to sync our daily activities to a roughly 24-hour cycle. This determines everything from our sleep patterns to our appetites and even dictates the time of day we are most likely to perform at our best.
However, not all of our body clocks keep the same time – some of us prefer early mornings while some of us prefer late nights. What’s more, alterations in external time, such as crossing time zones or changes to and from daylight saving time can play havoc with this finely tuned internal system.
In this episode, we catch up with Dr Beatriz Bano, a neuroscientist based at the University of Manchester.
She tells us the role exposure to daylight plays in setting our body clocks, how they change over our lifetimes and how we can set up our daily routines to ensure we are well rested and performing at our best.

Since the discovery of the double helix by Francis Crick, James Watson and Rosalind Franklin in the 1950s, human knowledge of DNA and genetics has grown almost immeasurably.
We now know that genes affect every aspect of our lives, from our appearance, our health and even our personality. But more than this, our genes are a living document of our evolutionary past, an ancient document that, if read properly, can reveal almost everything about how we came to be how we are.
In this episode, we’re joined by the evolutionary biologist and multi-million selling author Richard Dawkins to speak about his latest book The Genetic Book of the Dead: A Darwinian Reverie.
He tells us how different species of animals hit on the same evolutionary strategies despite being separated by multiple continents, how natural selection doesn’t necessarily always follow the perfect path and how a scientist of the future may one day be able to read the genetic code of any living animal like a book to uncover its entire evolutionary past.

We all love our dogs and want to do what’s best for them but, unfortunately, they aren’t able to talk to us to let us know when something isn’t going well for them. So how can we make sure we’re doing our best to keep them safe and happy?
In this episode, we catch up dog expert and author Zazie Todd to talk about her latest book, Bark!: The Science of Helping Your Anxious, Fearful, or Reactive Dog.
She teaches us about some key body language cues to look out for to tell when your dog is feeling anxious, shares her top tips on buying a healthy puppy, and explains why it’s always a good idea to let your dog have a good old sniff.

If you’re anything like Kelly and Zach Weinersmith, the idea of a mass human migration to space is exciting but, well, a little flawed. As they say in their new book, A City on Mars (shortlisted for this year's Royal Society Trivedi Science Book Prize): “An Earth with climate change and nuclear war and, like, zombies and werewolves is still a way better place than Mars.”
In this episode, we speak to Kelly about why we’re not likely to see billionaires rocketing off to Mars-based bunkers, what we might eat when we live in space, and how close we really are to moving to Mars.

For a relatively small country, England is home to an astonishing variety of habitats. From the low-lying grasses, gorse and heather that make up the heathland to the many rivers that make their way across our countryside and cities, each landscape has its own individual characteristics and charms.
In this episode, we catch up with farmer and best-selling nature writer John Lewis-Stempel to talk about his new book England: A Major Natural History in 12 Habitats.
He takes us on a tour of some of the country’s unique habitats, speaks about the flora and fauna we can enjoy there and tells us how the best way to interact with nature is to get your hands dirty.

Did you know that according to some psychologists we have two minds, not one? The first of these is our regular, analytical mind – the part of us that processes language and is home to our ego – and the second is a more primitive, animal mind that responds to our environment in a more automatic, intuitive way.
It is argued that learning how to listen more closely to our animal minds can help us to overcome stress, anxiety and trauma.
In this episode, we catch up with psychologist and author Steve Biddulph to talk about his latest book Wild Creature Mind.
He tells how our ‘gut feelings’ are a way of our animal minds trying to tell us something, talks us through some simple techniques we can use to help us be more in touch with our animal minds, and explains how simply being a bit kinder to ourselves is a great place to start.

Thanks to the advent of the smartphone, we now have in our pockets more computing power than NASA needed to put human beings on the Moon. With it comes access to vast amounts of information, both good and bad, and the ability to communicate like never before. But what impact is this having on our children’s lives and how should we approach their smartphone use?
In this episode, we’re joined by neuroscientist, author and BBC Science Focus columnist Dr Dean Burnett to talk about his latest book Why Your Parents Are Hung Up On Your Phone And What To Do About It.
He tells us why screen time isn’t anywhere near as bad for your kids as people say, why using search engines isn’t rotting their brains and how, far from being antisocial, phones can actually help younger people to develop and maintain their social lives.

Often, we’ll hear it said that we live in an uncertain world. Upon hearing this, most of us respond, well of course we do. But what does the term uncertainty actually mean when analysed under a scientific lens and how can we think about it more rationally.
In this episode, we catch up with Prof Sir David Spiegelhalter, Chair of the Winton Centre for Risk and Evidence Communication in the Centre for Mathematical Sciences at the University of Cambridge, to talk about his new book, The Art of Uncertainty: How to Navigate Chance, Ignorance, Risk and Luck.
He tells us how uncertainty essentially comes from our personal relationships with the outside world, how to analyse and express probability more effectively and why philosophers argue that there are several different types of luck.

Free will, as defined by the Encyclopedia Britannica, is the “supposed power or capacity of humans to make decisions or perform actions independently of any prior event or state of the universe”.
In a previous episode, neuroscientist Kevin Mitchell argued that human evolution has indeed equipped us with the capacity for genuine free will. Go and check it out if you haven’t already.
Now, we turn the spotlight on the opposing view.
In his latest book, Determined: Life Without Free Will, renowned neuroscientist and recipient of the prestigious MacArthur ‘Genius Grant’ Robert Sapolsky challenges the notion of free will, presenting a compelling case that our actions are largely determined by biological, environmental and chance factors.
In this episode, Sapolsky gets into the reasoning behind his controversial conclusions. But he also looks beyond just the lack of free will, exploring how this realisation might necessitate some fundamental changes to our society. And you know what? Even without the ability to truly choose, he still contends that life can hold real meaning.

Thanks to the years and years spent poring over textbooks to study the inner workings of the brain, the high level of manual dexterity required to perform operations and the mental pressures that come with taking patients’ lives in your hands, there can be little doubt the journey to becoming a brain surgeon is one of the most challenging any of us can embark upon.
So, what exactly does it take to become a successful brain surgeon and what does the day-to-work reality look like when the years of training are finally complete?
In this episode, we catch up Theodore H Schwartz, professor of neurosurgery based at Weill Cornell Medical Center, to talk about his new book Gray Matters: A Biography of Brain Surgery.
He tells us about his own personal journey to become an in-demand surgeon, what it’s like to work in one of New York’s busiest hospitals, and the surprising crossover between brain surgery and learning how to play an instrument.
