What really happens in our brains when we sleep
Every night when we fall asleep, our brains and bodies switch into a mode of functioning that’s entirely different from that of our waking lives. During sleep, our bodies become essentially paralysed, and our brains conjure up bizarre scenarios through dreams or even nightmares. But what exactly is happening during this period of our daily lives, why do we do it in the first place, and what can we
How evolution made the strangest creatures on Earth
Evolution by natural selection has given rise to a fascinating tapestry of living organisms, each occupying their own individual niche. The result is a world filled with a dizzying array of weird and wonderful creatures that won the battle for survival in bizarre and fascinating ways.
In this episode, we’re joined by evolutionary biologist and author Prof Richard Dawkins to talk about his latest
The often-bizarre history of mind-machine interfaces
Since the discovery of electricity, scientists, inventors and engineers have attempted to figure out ways in which this often-mysterious force could influence our brains and behaviour. History is littered with all manner of wild experiments, many of which were less successful than others, but could it be that we’re entering an age in which it’s possible to not only manipulate the electrical impuls
Why our brains crave answers and the psychology of explanation
Almost as soon as we are able to speak, we start asking our parents, relatives, and teachers an almost frustratingly large number of ‘why questions’. It’s an essential part of the natural human desire to understand the world in which we live. However, answering these questions is often much more complicated than it may first seem. What makes one explanation easier to understand than another, and h
Why our online lives are making us sick and how to fix it
Over the last decade or so, it’s become abundantly clear that eating a diet based on ultra-processed food is damaging to our bodily health. Could it be that our information diets, the deluge of content we consume online every day, is having a similar detrimental effect on our mental health?
In this episode, we’re joined by technology lawyer and author Seb Butcher to talk about his latest book, Di
Why tuning into your body’s natural rhythms is the key to productivity
Sometimes, no matter how busy we are or how hard we work, when we look back on our day, it can seem like we didn’t really achieve very much. Why is this and what can we do to make more effective use of our time? Could the answer be simply tuning into our bodies’ and minds’ natural rhythms – more specifically the ultradian rhythm, the 90-minute cycles of attention and alertness that oscillate throu
How maths underpins almost every aspect of our lives
For many of us, maths is simply a subject we studied at school to help us learn how to count, add one thing to another, and carry out everyday tasks such as managing our personal finances. But if we look more deeply, maths has underpinned the way that humans understand and interpret the world for thousands of years. Without our knowledge of maths, we’d have no smartphones and no internet, our buil
Why bogs are one of the planet’s most undervalued ecosystems
For those of us who live in towns and cities, bogs may seem to be a rare environmental relic left over from times gone by, or perhaps something we’ve only encountered onscreen in spooky fantasy movies. The fact is that these peat-rich, often otherworldly landscapes are found in almost every corner of the globe, have had a deep influence on the development of human culture, and act as one of the pl
Why leaves are one of nature’s most versatile creations
From the neatly curated English country garden to the wild jungles of the Amazon, the Earth is host to a staggeringly diverse range of plant life. One of the key reasons for the great evolutionary success of plants is the wide-ranging versatility and utility of the leaves that grow on them.
In this episode we’re joined by Prof Jonathan Silvertown, an evolutionary ecologist based at the University
How to make buildings without harming the Earth
Every built environment we spend our time in, our homes, offices, music venues or sports stadiums – is designed and constructed after hours of consideration about form and function. Oftentimes, less consideration is given to the impact this has on the health of the planet.
In this episode, we’re joined by Will Arnold, an environmentalist, engineer, and author, to talk about his latest book, Futur
Why humans are wired to appreciate beauty
A late summer sunset, a peaceful, verdant forest, or a Shakespearean sonnet – these are all things that move us emotionally thanks to what we perceive as their beauty. But why is this so, why do environments, art, music, and even ideas move us so emotionally?
In this episode, we’re joined by Prof Nicholas Humphrey, an evolutionary psychologist and author, to talk about his latest book, Why Is the
How safety engineers test everyday products to destruction
Whenever we buy a new product or use a service, we simply expect it to work as advertised, usually without giving much thought to how it came to being in the first place. However, behind the scenes, every piece of technology we use, be it a toaster, a lawnmower or even the aeroplane we travel in when we head off on our holidays, has gone through a rigorous series of tests to ensure its safety and
Why we need to be taking asthma more seriously
Currently, around one in ten of us are living with asthma. For many, the symptoms can be relatively mild, but for others, attacks can be severe, debilitating, and even life-threatening. For the most part, we’ve relied on the same method of treatment to manage the condition for the last few decades. However, new research is showing great promise in helping those who suffer from this often-overlooke
What our evolutionary history can teach us about eating well
These days, supermarket shelves are filled with thousands of different products all vying for our attention; the options are almost endless. However, if we look back in time, we find that our early ancestors simply ate what they were able to hunt and gather and eventually farm. Thanks to the huge number of options we now have available, many of us choose to follow diet plans of various kinds, be i
Why Smell is Our Most Overlooked Sense
Though often thought of as the poor cousin to our other senses, our sense of smell has played a key role in human life since its very beginnings. It helps us to determine whether certain foods are safe to eat, protects us from environmental dangers such as fire, mould and toxic chemicals, and has even been weaponised for use as a form of racial or economic discrimination. Without it, the world wou
Are We Living in a Simulation? How to Tell If Reality Is Fake
The possibility that we may be living in a simulation created by a more technologically advanced civilisation has occupied the minds of scientists, philosophers and fiction writers for decades. We may never be able to satisfactorily answer this question, but perhaps the best way of investigating its feasibility is by looking at how we might go about creating a simulation universe ourselves.
In th
Why we need to rethink our ideas about laziness
Often in life, we find ourselves being accused of being lazy or accusing others of acting lazily, or maybe even becoming frustrated by what we see as laziness in our own actions. But what do we really mean by the term laziness, why is it viewed as a taboo that transcends cultures, and what effect does considering ourselves or others lazy have on our mental health?
In this episode, we’re joined by
Why interpersonal conflict is a natural, healthy part of life
No matter how gently or politely we live our lives, at one point or another, it’s inevitable that we’ll find ourselves in a situation in which we disagree with another person and find ourselves having to defend our opinion or perspective. For many of us, these situations are hugely uncomfortable, perceived as destructive, and are to be avoided at almost all costs. Why is this, could interpersonal
The hidden reasons common knowledge shapes our lives
When we know a certain fact about the world or hold a certain belief how do we know that others also know this, how do we base our thoughts and actions on our knowledge of what we assume others know, and what impact does this have on the way that society as a whole functions?
In this episode, we’re joined by Steven Pinker, a professor of psychology at Harvard University, best-selling author and t
Why understanding how time works is the biggest mystery in science
When most of us think about time our minds likely turn to thoughts of the second hand that ticks around a clock, or maybe the occasions we’ve been late to catch a bus. But if we stop to think about what time actually is things quickly get more subtle and complicated. Does time only exist in our minds as a psychological illusion, does it really only run forwards and not backwards, and how close is
How forensic scientists gather vital evidence to solve crimes
Whenever a crime is committed, tiny traces of evidence are left behind at the scene, which, if pieced together correctly, can tell us exactly what happened, when it happened and who was responsible. This is the job of forensic scientists. But how exactly does this process work, how accurate are the portrayals of crime scene investigators we see on film and TV, and what happens if when mistakes are
Why the most extreme El Niño event for a century is on its way
Every several years, the surface temperatures of the Pacific Ocean rise, triggering a climate event that has a domino effect on weather patterns across the globe. This is known as El Niño – and this year, meteorologists predict we’re in for a big one. But how exactly do these events occur, how big an effect is climate change having on their frequency and impact, and what can we expect to see in th
The secret world hidden in the ground below us
Though we’re often not aware of it, the ground beneath our feet is teeming with an abundance of life and activity – from the complex networks of fungi and tangled roots put down deep into the Earth by the plants that live on its surface to the staggering variety of organisms that make their homes in the damp and darkness of the soil. This vast, fascinating ecosystem is vital for the health of the
The truth about the Nazi fascination with alternative medicine
It’s widely documented that during the time of the Third Reich, the Nazi Party employed a legion of scientists to aid them in their goals of military superiority and ethnic cleansing – particularly in their pursuit of eugenics and development of cruel nerve agents and chemical weapons. It’s far less known that Heinrich Himmler, one of the primary architects of the Holocaust, considered himself to
What we’re getting wrong about narcissists
Oftentimes in popular culture we’ll hear the term narcissist used to describe a person who has an inflated opinion of themselves, a big ego or someone who tends to overestimate their own abilities. However, in psychology, narcissistic personality disorder is defined as a diagnosable mental health condition that can cause just as many issues for those living with it as it does for those around them
The latest breakthroughs in Parkinson’s research
Parkinson’s disease currently affects more than 160,000 people in the UK. It’s a complex, progressive condition that typically develops slowly over many years and causes issues with movement, balance, and quality of life, and currently has no known cure.
In this episode, we’re joined by Prof David Dexter, director of research at Parkinson’s UK, to talk about the latest exciting developments in
How to harness your brain’s underused superpowers
For a large proportion of our lives, our brains seemingly
work on autopilot – the many processes the brain controls hum away behind the scenes, helping us to carry out our daily tasks. But in certain scenarios, our attention takes over, giving more conscious control of our actions. These processes, such as memory, planning and our emotional responses to the situations we find ourselves in, are kno
How we define intelligent life
What does it mean to be a living organism? What are the
driving forces that motivate our thoughts and actions? Are we all simply acting the way we do thanks to the instructions built into our genes and our automatic responses to the environments we live in?
In this episode we’re joined by researcher, broadcaster and author Melanie Challenger to talk about her latest book, Alive: The Hidden Intel
Exploring Darwin’s ideas through a queer lens
When Charles Darwin published On the Origin of Species in the mid-nineteenth century, his theory of evolution by natural selection turned many of the scientific ideas of the day on their heads. The influence of the book was so profound that scientists are still studying its many implications to this day. And it turns out that, if we look closely enough, we find that investigating queerness in natu
On the frontlines of our fight against dementia
Currently there are around one million people in the UK living with dementia. Despite significant advances in our understanding of the disease over the past several decades an effective cure is yet to be found. However, recent breakthroughs made by researchers around the world are showing great promise in the treatment of this devasting condition.
In this episode, we’re joined by Prof Selina Wray
Why the search for life on Mars is far from over
Way back in 1976, NASA’s Viking landers touched down on Mars to search for potential signs of microbial life that could currently exist on the planet’s surface. Despite the mission making a number of promising discoveries, so far, no further landers have returned to the surface of the Red Planet with the aim of repeating these fascinating experiments. As such, many questions still remain as to wha
Why rediscovering simple pleasures may be the key to happiness
Every single day of our lives, we’re exposed to a vast multitude of experiences and interactions with the various people, objects and technologies in the wider world that surrounds us. The chances are that many of us give these moment-to-moment encounters very little thought. But could it be that our desire for convenience, efficiency and productivity has resulted in a widening rift that has ultim
Why human urine may be our most untapped natural resource
While largely viewed as a toxic waste product with no practical use, our urine is actually rich in all manner of valuable nutrients that, with a little effort, can be extracted, recycled and converted into fertiliser for use on food crops, used to make building materials or even used to generate electricity.
In this episode, we’re joined by Kai Udert, a researcher based at the Swiss Federal Insti
How new technology can change our emotional lives for the better
It’s clear to all of us that the rapid progress that technology has made over the last century or so has had profound impacts on almost every aspect of our lives. But often, the impact on our emotional well-being associated with these great changes is overlooked, or, if mentioned at all, portrayed in a largely negative light. Why is this? Is it simply down to our innate fear of the new or our natu
The birth, evolution and future of microchips
It’s a good bet that if most of us were to glance around our living rooms or offices, we’d quickly spot all manner of electronic devices that are powered by microchips. Since their introduction in the 1950s, chips have become one of the fundamental building blocks of the various digital technologies we rely on in our daily lives. What impact has this had on the development of technology, economics
What we can learn from music’s ability to evoke images in our minds
For most of us, music has a unique, almost supernatural, ability to trigger our emotions and memories and conjure up evocative images or even fantasies in our minds in a way that few other experiences or art forms can. But what exactly is happening in our brains when we listen to music, is there such a thing as a common musical experience that’s shared by people from different cultures and backgro
Why the liver is the body’s most misunderstood organ
Most of us think about the liver as simply being the body’s filtration system that acts as a sponge that removes toxins from our bloodstreams. But the truth is it performs many more functions that are vital for our health such as acting as the primary organ in regulating our metabolisms, storing essential nutrients our bodies can draw from in times of need, and even producing proteins that help ou
Why this common women’s health condition is so misunderstood
Despite affecting as many as 80 per cent of women by the age of 50, fibroids, lumps of tissue that grow in or around the womb, are not commonly discussed outside of specialist doctors’ offices. However, they can cause a whole host of health issues, such as heavy or painful periods, poor bladder control, chronic constipation, and even affect fertility and complicate childbirth.
In this episode, we
The miraculous healing ability of our brains
It was previously thought that once our brains suffer an injury due to stroke or trauma, the potential for recovery was severely limited. But recent developments in medicine have proven that this isn’t the case; our brains are, in fact, capable of miraculous acts of healing. This is thanks to a process known as neuroplasticity, a concept that’s changing the way that medical practitioners are helpi
How parasites play a vital role as caretakers of Earth’s ecosystems
When most of us think of parasites, our minds will likely turn to thoughts of the various icky creatures that can invade our bodies, make their homes there and end up making us ill. But the truth is that parasites make up a hugely significant part of all life on Earth and bring many benefits to the organisms they live in or alongside and the wider ecosystems they are a part of.

How to keep your body younger for longer
When it comes to the effects of ageing on our bodies, there are many more factors at play than simply the number of years we’ve been alive. It turns out, that for some people, there is a huge gap between their chronological age and their biological age – the scientific measure of how well our cells, tissues and organs are functioning compared to the global average. But what are the main drivers of
Why wasps are one of the planet’s most misunderstood insects
The truth is, when most of us think of wasps, our minds will likely go to memories of irritating winged pests landing in our drinks when we’re trying to have a nice summer picnic or perhaps one of the times we got a nasty sting when we were out playing in the park as children. It’s fair to say wasps have a pretty bad rap. But if we look more closely, it soon becomes clear that most of us are getti
Why you probably don’t need to be taking dietary supplements
These days the supplement industry is booming – supermarket shelves are stacked high with all manner of pills and powders claiming to do everything from helping us to live longer or improving our digestive health to boosting our energy levels or even improving our ability to concentrate and focus. How have we reached this point, why do many of us feel our diets aren’t giving us everything we need
Why this tiny organism is essential for the health of the planet
Although it often goes unnoticed, plankton is the most abundant form of life in Earth’s oceans, making up 95 per cent of all oceanic biomass. These tiny organisms are responsible for generating around half of the planet’s oxygen, play a vital role in the oceans’ food chains and were around for millions of years before we humans came onto the scene. Simply put, without plankton, the world would be
What happens in our bodies when our hormones misfire
Every minute of every day, our bodies are flooded with a complex web of hormones – chemical messengers that travel through the bloodstream, coordinating everything from our blood pressure, body temperature, metabolic rate and even our emotions. When this system is functioning correctly, we barely notice its actions, but if it begins to misfire, it can lead to profound issues in everything from flu
What we can learn about parenting from the animal kingdom
Becoming a parent is undoubtedly one of the biggest events that can occur in any of our lifetimes – suddenly we have a tiny living being to take care of that demands the majority of our thoughts, time and attention. Of course, this can at times feel overwhelming and often leads us to look for help and advice from our parents, grandparents or close friends. But what strategies do parents in the ani
Don’t miss the upcoming Nature’s Unsung Heroes miniseries!
While the larger, more impressive or charismatic animal and plant species often receive the most attention, the natural world is filled with lesser-known or even misunderstood organisms without which life on planet Earth would look very different indeed.
If you’d like to learn how plankton plays a vital role in regulating the health of the entire planet, how, despite being a bit icky, parasites p
Why bisexuality is everywhere
In June of every year, the LGBTQ+ community across the world comes together to celebrate Pride Month – an annual event that began in 1970 to promote awareness, visibility and equality for lesbian, gay, bisexual, transgender and queer individuals.
In this episode, to coincide with Pride Month, we’re joined by Dr Julia Shaw, a broadcaster, best-selling author and psychologist based at University
The past, present and future of DNA science
Whether it’s the swab tests many of us use to help us piece together our family trees, the painstaking detective work carried out by forensic scientists, or its use in medical screening to look for signs of our predisposition to develop certain diseases, DNA science has become a regular fixture in news stories, pop culture and dinner table conversations in many of our homes. But how exactly do the
Why ecoacoustics is the future of conservation
Traditionally, ecologists wanting to take stock of the diversity, health and population levels of animal species within a given environment have needed to tie on their boots, get out in the field and painstakingly record what they are able to observe manually. But the emerging field of ecoacoustics – the use of sound recording to survey the biodiversity within ecosystems – is promising to be a gam
Unlocking the invisible rainbows of the Universe
Our world may look vibrant and full of color. But in reality, our human eyes are only picking up the tiniest slice of all the light shining in the Universe. To astronomers this hidden light is just as important as the red greens and blues we can see. We talk to Alfredo Carpineti about what secrets are lying in the Universe beyond human vision, while celebrating another aspect that the rainbow has
Why birdsong is the pop music of the natural world
When it comes to the sounds we encounter in the natural world, few have the beauty, elegance and variety of birdsong. But these distinctive vocalisations are not simply static calls that are common to all birds of a certain species that are passed on from one generation to the next. They vary from region to region and even evolve in single populations over time in much the same way that the style
Why walking more is the best thing you can do to boost your health
Over thousands of years, human beings evolved to walk upright on two legs, efficiently and over long distances. But these days, thanks to changes in our lifestyles, we’re becoming more sedentary than ever, and this is having profound effects on our health and well-being.
In this episode, we’re joined by Courtney Conley, a doctor of chiropractic medicine, and Milica McDowell, a doctor of physical
How ultrasound tech could save hedgehogs
Hedgehogs are in decline all over Europe. These prickly little fellas are faced with so many threats – in their rural habitats, in our gardens, and on our roads. But new research about hedgehog hearing could help us protect these adorable creatures from going extinct.
As part of our Science of Sound miniseries, we speak to Dr Sophie Lund Rasmussen, a scientist who has dedicated her life to hedgeh
Why ADHD is so challenging to diagnose
Attention Deficit/Hyperactivity Disorder, or ADHD, is currently thought to affect around one in 20 of the world’s population, making it one of the most prevalent types of neurodivergence. Despite this, the condition is still surrounded by stigma, misunderstanding and significant challenges in diagnosis.
In this episode, we’re joined by Prof Ellie Dommett, a neuroscientist based at King’s College
Inside the project helping the hard of hearing listen to music
The vast majority of us take listening to and appreciating music for granted. But for those of us living with hearing loss, continuing to enjoy our favourite songs, symphonies or dance tracks can be something of a challenge. Maybe we find it difficult to distinguish one instrument from another, have a reduced ability to hear pitch, or struggle to make out a song’s lyrics.

Why your Neanderthal genes may be affecting your health
There’s so much we don’t know about Neanderthals. Our stocky, muscular relatives went extinct around 40,000 years ago, leaving a trail of mystery in their wake – about what they were like, how they lived, and why they disappeared. But, while Neanderthals themselves have gone, fragments of their DNA live on inside us.
In this episode, we speak to Prof Chris Stringer, scientific associate at London

How to help your brain thrive in a rapidly changing world
For thousands of years, the evolution of the human race has been driven by natural selection and the passing on of genes that have helped us to thrive in the environments we live in. However, in current times, advances in technology and rapid societal change are shaping our lives like never before. So, what impact is this having on the way we think and act, and how can we best position ourselves t
How to break free from imposter syndrome
No matter our level of ability, talent or achievement, at times some of us feel like we’re a fraud and have simply been blagging our way to success. This is known as imposter syndrome. While it’s not formally recognised as a clinical mental health condition, it can still play a significant role in our wellbeing. So, why are so many of us prone to these nagging feelings of self-doubt and inadequacy
The dawn chorus – why birds sing at the break of day
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 thi
How to save the planet’s forests
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
How flowers played a key role of the evolution of life on Earth
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,
How chemistry underpins every area of our lives
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 eve
How to engage more deeply with the natural world
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
You’ve been pooping wrong, but here’s how to fix it
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 p
Why it’s not too late to reverse Earth’s extinction crisis
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
Why gout is on the rise, and how to lower your risk
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
How our intimate relationship with animals shaped human evolution
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
Why our brains struggle to keep up with a rapidly changing world
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
Why we need to save ugly, creepy, scary and misunderstood animals
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
How we look at the Universe with a radio

The best ways to spot a liar
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.

Why understanding what makes us hungry is key to weight loss
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
How to slash your dementia risk in 12 weeks
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
Why connecting with others is vital for our mental health
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
How metabolism really affects your health, weight and wellbeing
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
What faces reveal about us and the societies we live in
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
How our planet connects to the Solar System around it
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
How AI could help us create life from scratch
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
