In springtime, as the Sun rises, the early morning air is filled with the glorious sound of birdsong. This is known as the dawn chorus. But why exactly are birds so vocal at this time of the day, what purpose does it serve, and how did their songs get so complex? In this episode, we’re joined by the RSPB’s Adrian Thomas, a bird expert and author of the RSPB Guide to Birdsong. He explains how this...

Forests cover around one-third of all landmass on Earth and, as such, play a key role in the ecological health of the entire planet. However, thanks to decades of exploitation, climate pressures and natural disasters, this vital resource is beginning to struggle. So, what can we do to help these essential environments thrive? In this episode, we’re joined by Suzanne Simard, a professor of forest e...

For most of us, our experience of flowers is limited to sending a bouquet to our loved ones on special occasions or perhaps picking up some pretty plants from the garden centre to cheer up our homes. But if we take a wider, more nuanced view, it quickly becomes clear that flowers have played an essential role in the evolution of the vast and varied ecosystems of the planet we live on. The fact is,...

While we may not always be consciously aware of it, chemical processes are busy whirring away every second of every day, no matter what we’re doing or where we look. Be it the reactions that continuously occur in our own bodies to keep us alive, the manufacturing processes used to make the clothes we wear, the homes we live in and the products we rely on to make our lives more comfortable, or even...

Perhaps due to poor weather, the COVID pandemic, or a simple lack of motivation, these days many of us spend a lot of our time indoors. However, wherever we live, there are always opportunities to get out into nature and learn more about the world we live in. Doing so can not only enrich our own lives by more deeply engaging with the environments that surround us but can also help scientists and r...

Smelly, dirty and a bit embarrassing – we tend to treat our poo as a private matter, to be dealt with in the bathroom and then stringently ignored. But, while we may not want to discuss toilet time at the dinner table, our bowel movements can give us invaluable information about our wider health. In this episode, we speak to Dr Trisha Pasricha, a gastroenterologist, medical doctor and assistant pr...

Planet Earth is currently facing its sixth mass extinction event, with hundreds of species of plants and animals being lost for good every single day. For the first time in history, this devastating loss of the world’s flora and fauna is not being caused by natural phenomena, but by the actions of human beings. However, there is still hope that, if we start to take steps in the right direction, th...

If you were to mention the term gout, the chances are that most of us would think of the gluttonous sovereigns of yesteryear who ended up with the condition after years of gorging on rich foods and drinking fortified wines. But the fact is, cases of gout have been climbing significantly over the past few decades. So, what’s behind this increase and what measures can we all take to help us avoid th...

Thanks to our highly developed brains, sophisticated ability to communicate and use of advanced technology, it can be easy to think that we humans are separate from, and even superior to, the animals we share the Earth with. But the truth is that animals have profoundly influenced the progress and evolution of human beings for tens of thousands of years. In this episode, we’re joined by science wr...

The human brain is undoubtedly one of the true marvels of nature. But many of the neural mechanisms that evolved to keep our ancestors alive over thousands of years are now leaving us feeling dissatisfied, anxious and depressed thanks to the rapid advances in technology and culture we now find ourselves faced with. The simple fact is, we’re living in an environment that our brains were not built t...

The natural world is filled with a rich tapestry of creatures, each occupying a unique evolutionary niche that helps to keep the ecosystems they live in functioning healthily. But the truth is, over the centuries, we humans have treated some of them better than others. Our tendency is to prefer cute, cuddly animals such as pandas or donkeys, or beautiful, majestic beasts such as elephants, eagles...

There’s an entire cosmos hidden from our human eyes. The only way to see it is by looking at the Universe with a radio.

How can we tell if someone we’re speaking to is being economical with the truth? Oftentimes, we’re told that the primary telltale signs lie in the use of body language – maybe someone is avoiding eye contact, touching their face a lot, or fidgeting and squirming. But there’s also a whole world of clues to look out for in the type of language that someone uses when they’re telling us lies. In this...

Chances are that if any of us are looking to drop a bit of excess weight, the first thing we’ll attempt is to cut down the number of calories we’re consuming. For decades, we’ve been told that balancing the number of calories we put into to our bodies with the energy that we burn can help us to maintain a healthy weight. While this is true, could it be that we’re putting our attention and effort i...

Around the world, more than 50 million people are living with some form of dementia – a number expected to triple by 2050 as populations age. But the thing is, dementia is often talked about as a kind of genetic lottery. You either get lucky and escape it, or unlucky and develop it. But what if that framing is wrong? What if far more of our brain health is within our control than we’ve been led to...

Statistics show that half of us will experience a mental health condition of some kind by the time we turn forty. Could this be due to the increasing pressures and looming crises we’re currently facing in the modern world, overstimulating natural responses in our brains and bodies that have evolved over hundreds of thousands of years to protect us from threats? In this episode, we’re joined by Dr...

Whether we’re working at a desk in an office, running a marathon or even asleep in bed, our bodies are host to thousands of chemical processes that are continually converting the food we eat into energy and repairing our bones, muscles and organs. Collectively these processes are known as the metabolism. But how are they affected by our genes, lifestyles and diet, and what can we do to make sure e...

The human face contains more than 40 muscles, giving us an ability to visually express our thoughts and emotions that is unique in the animal kingdom. This has perhaps led to a long-held obsession to uncover the many mysteries of our faces that has persisted in everyone from artists, scientists and even anthropologists for thousands of years. But where is this trend heading? And is it doing more h...

We often think of our planet as an isolated island, solitary and cut off from the cosmic ocean it resides in. But the truth is, Earth is intimately connected with the Universe surrounding it. What’s more, by learning more about the Solar System around us, humanity has changed its own view of the world as well. Dr Dagomar Degroot from Georgetown University spoke to us to explore this idea in more d...

For the last several billion years, all life on Earth has progressed according to the rules of evolution by natural selection – a step-by-step process that has given rise to the fascinating complexity and beauty of all the living things we share our planet with. But now, due to advances in our knowledge of genetics and the rise of artificial intelligence, we’re on the brink of being able to design...

The chances are that if any of us were asked to describe what it feels like to be in love we’d turn to art, poetry or music to help give us the answer. But what does science have to say about this uniquely human experience? In this episode, we’re joined by Dr Justin Garcia, an evolutionary biologist and sex researcher based at the Kinsey Institute in the US, to talk about his book, The Intimate An...

Over the past several decades, many technologists and policy makers have sought out huge, disruptive shifts in thinking in almost every area of science, business and commerce in the hope that they’d help to drive innovation forward in giant leaps, one brilliant new idea at a time. But how successful has this been, and should we instead be focusing on a more gradual, incremental approach to innovat...

If most of us are put on the spot and asked to name acts that we think would define a person as evil, it’s likely our minds would turn to murderers, rapists and war criminals, to name a few. But could it be that this commonly held conception of evil isn’t merely just an oversimplification, but rather a deeply flawed way of viewing the world based on a litany of personal biases, and one that is in...

From famous actors and pop stars to the legions of social media influencers with millions of views, it seems almost everyone has something to say about the best ways to boost our health and wellbeing. But is this trend leading to many of us bypassing traditional sources of health advice and care such as GP practices and government health services and instead turning to the Internet, social media a...

While the human mind is capable of great insight, original thoughts and acts of tender kindness towards others, it can also, at times, act like our own worst enemy. Feelings of worthlessness, shame and disappointment can all stem from our brain’s natural inclination for overthinking. This can give rise to a wide range of debilitating impacts on our lives, such as low self-esteem, anxiety and depre...
