Our Editor's Take

Why? is a series that seeks answers to inspiring and curious questions. Each episode focuses on a single scientific topic. For instance, one installment debates if and when humans will become extinct. It explores the reasons that might bring the specie's demise and how long before they occur. Another episode investigates why music makes people emotional. It explains the physiological responses in the brain and the science behind them.

The science podcast has a rotating panel of hosts from Britain. Each of them has notable accomplishments related to content creation. First, there's Emma Kennedy, who has published best selling books. She also wrote scripts for theater and radio. Olly Mann has created many successful podcasts like Answer Me This!, The Modern Mann, and The Week Unwrapped. He is also a famous BBC broadcaster.

Luke Turner is a journalist who has written for The Guardian, Vice, and NME. He is the cofounder of the music website The Quietus. Dr. Anna Machin, a fourth podcast host. She's received worldwide recognition for her work in evolutionary anthropology. Dr. Machin wrote Life of Dad and Why We Love and appeared as an expert on multiple TV shows.

The podcast invites experts from a variety of fields to share their expertise. There are interviews with neuroscientists, microbiologists, and physicists. Even experts from NASA contribute their knowledge to the show. Each episode includes facts along with immersive sound design and music from DJ Food.

Every host brings their distinctive expertise to the conversations. For instance, Turner leads many of the music-related segments. In one episode, he talks about his personal experience listening to music as a child. Turner discusses turning that obsession into his career as a journalist.

Machin hosts an episode asking whether people can trust their own eyes. She uses her knowledge to explore how the brain processes information and how accurate it is. Other installments talk about regional accents in animals and parallel universes.

In this podcast, the panel of hosts intrigue listeners in their search for answers to thought-provoking questions. New episodes of Why? come out on Mondays and Thursdays.

Will robot soldiers replace human armies?

Will robot soldiers replace human armies?

From Terminators and Cylons to the War Droids from Star Wars, military robots are staples of science fiction. But they’re already here in the real world too. The US, China and Russia are all investing efforts into military machines – but they won’t be the gun-toting humanoids we see onscreen. Would taking human fighters off the battlefield increase the peace? Or should we be gravely concerned about this new era of international war? Today on Why?, Emma Kennedy speaks to Kelsey Atherton, an award-winning military-tech journalist and Chief Editor of the International Policy Journal. • “Militaries are deeply invested in the idea that things flow from the top.... The more autonomy you give a machine the harder it is to put in command and control.” - Kelsey Atherton • “If a robot makes an error, it’s on the person who programmed it… these weapons are brought to battle with errors built in.” - Kelsey Atherton WHY? is written and presented by Emma Kennedy.

Could we live on the moon?

Could we live on the moon?

It’s been 52 years since humans last stepped onto the moon, and NASA is determined to set up a permanent base there. But there are huge challenges to overcome - not least surviving brain-damaging solar radiation and bone-wasting partial gravity. Today on Why?, Luke Turner speaks to Clive Neal, Professor of Planetary Geology at Notre Dame University currently working with NASA on their next moon mission and find out exactly how they plan to build a long-lasting habitat. • “What we’ve learned during and since Apollo, is that the moon is a very hostile environment, but now we understand the nature of that hostility. And that understanding is key to being able to keep humans alive on the surface of the moon – not only to survive, but to thrive.” - Clive Neal • “Radiation and humans don’t miss in the long term. Radiation is much more intense in the lunar environment. So a human habitat on the moon would have to be buried beneath about two meters of regolith to protect them.” - Clive Neal Written and presented by Luke Turner.

Should I be able to live forever?

Should I be able to live forever?

Most of us would like to live for as long as possible, given we’re in good health. But the definition of a long life is changing, and the rapid advancement of anti-ageing technologies could transform the idea of immortality from fantasy to reality. So the question isn’t so much can we live forever, but should we? Anna Machin talks to Dr Stephen Cave, Director of the Institute for Technology and Humanity at the University of Cambridge, and co-author of Should You Choose To Live Forever? A Debate, to find out. • “If we’re serious about pursuing longer lives, we have to get really, really serious about making those lives sustainable”. • “With life-extension and anti-ageing technologies, the effects will be enormous. Many of them will be beyond what we can imagine right now. If we’re going to pursue them, we need to think of what we can do to maximise the benefits, and manage the risks.” WHY? is written and presented by Anna Machin.

Could we really live on Mars?

Could we really live on Mars?

Humanity has always been fascinated by the prospect of living on another planet – and our nearest neighbour is the prime candidate. Could we create livable space on Mars? What would we take with us? How would our lives be different? And how would human society change? As climate change and war make the question more urgent, we ask: Could humans really live on Mars? Anna Machin talks to Why?’s first husband-wife duo, A City on Mars authors Kelly and Zach Weinersmith, about life for the first Martian settlers. • “People talk about Mars as a backup for humanity. But if it means taking so many steps back on human rights, I don’t want that backup. Let’s wait until we can support everyone who is up there.” - Kelly Weinersmith • “If we do send humans to Mars, it needs to be done very slowly. It probably won’t happen in my lifetime.” - Kelly Weinersmith Buy A City On Mars through our affiliate bookshop and you’ll help fund WHY? by earning us a small commission for every sale.

Would I survive a disaster?

Would I survive a disaster?

With the news full of war, terror and natural disasters, it’s increasingly looking like the so-called Doomsday Preppers were on to something after all. But most of us still don’t have a clue what – or how – we’d do in a disaster scenario. So when catastrophe does strike, is there a science behind who is more likely to cope? And what can we do to increase our chances? Luke Turner talks to Dr Sarita Robinson, Associate Dean at the University of Central Lancashire and an expert in survival psychology, to find out what it takes to survive when disaster strikes. • “Our brain is very switched on to the idea of threats in our environment. Once we’ve established there’s something that will cause us harm, our bodies and brains are very quick to mitigate the risk.” - Dr Sarita Robinson • “Cognitive flexibility and optimism are both really helpful to survival in emergency situations.” - Dr Sarita Robinson WHY? is written and presented by Luke Turner.

When will humans go extinct?

When will humans go extinct?

Everything goes extinct eventually. When will it be our turn? And will humans disappear because of shifting tectonic plates, catastrophic natural disasters, the earth being engulfed by the sun… or our own ruinous activities? Basically, how long have we got? Dr. Henry Gee, senior editor at Nature and author of A Very Short History of Life on Earth, tells Olly Mann that it isn’t so much a question of if we will go extinct, but when and why. • “My feeling is that humans will become extinct within the next 10,000 years or so.” – Dr. Henry Gee • “For most of human history, people have been living at a subsistence level. Populations of humans would become extinct quite regularly. Near-extinction is a feature of human evolution." – Dr. Henry Gee Buy A Very Short History of Life on Earth through our affiliate bookshop and you’ll help fund WHY? by earning us a small commission for every sale.

Am I living in a hallucination?

Am I living in a hallucination?

You can trust what’s in front of your eyes, right? Turns out… not really. Everything we see is processed through a filter of our prior expectations. Our brains fill the gaps in the data they receive to create a “reality” that we can understand. If everything we see and hear is just a construct, are we all living in our own hallucinations? Anil Seth, Professor of Cognitive and Computational Neuroscience at the University of Sussex and author of Being You: A New Science of Consciousness, explains our world of illusions to Olly Mann. • “There is a real world out there – but we experience it as a construction. We never experience things as they really are. We experience the world as WE are, not as IT is.” – Anil Seth • “We think our brains are ‘reading out’ the world but it is totally the other way around… The brain is continually making predictions about what is out there.” – Anil Seth Buy Being You: A New Science of Consciousness through our affiliate bookshop and you’ll help fund WHY? by earning us a small commission for every sale.

Why does music make us emotional?

Why does music make us emotional?

Music is a universal language, a connecting force during all of life’s highs and lows. But why does music make us emotional? From feelings of elation and melancholy, to unease and motivation - why and how does music play with not only our emotions, but our brains themselves? Catherine Loveday, Professor of Neuropsychology at the University of Westminster, joins Luke Turner to discuss the psychology of music, its impact on our memory and why our teenage music loves stay with us forever. • "Music is in masses of different areas of the brain, and when we look in brain scanners when people are improvising, performing, or listening to music we see huge amounts of activation” - Prof Catherine Loveday • “There is research that shows longer-term musical memories are robust, and are less likely to be impacted by conditions such as dementia than other memories” - Prof Catherine Loveday • "There is a theory that music was our communication tool from before we developed language” - Prof Catherine Loveday • "There is no consistency in what people choose as their favourite genre of music, everyone develops their own taste and love of particular types of music” - Prof Catherine Loveday WHY? is written and presented by Luke Turner.

The secret life of pets: How does my dog’s mind work?

The secret life of pets: How does my dog’s mind work?

Your dog is really clever, right? You understand one another. Every pet owner thinks this. But can our pets really communicate with us beyond the basic demands for food, walks and play? How is its mind constructed? What’s going on inside that furry head? Dr Juliane Kaminski, Associate Professor in Comparative Psychology and director of the Dog Cognition Centre at the University of Portsmouth, tells Emma Kennedy how we’re only just beginning to understand how dogs see and understand the world they’re living in. • “Dogs have a huge motivation to look into our eyes, to maintain eye contact, which is not a trivial thing, because in the wild, a wolf would perceive this as a threat.”- Dr Juliane Kaminski • “We’ve created a creature that understands us in ways that no other animal does. Dogs are really good at making sense of our communication.” - Dr Juliane Kaminski WHY? is written and presented by Emma Kennedy. Produced by Eliza Davis Beard. Audio production by Jade Bailey.

What is the most powerful thing in the universe?

What is the most powerful thing in the universe?

They shine as brightly as a trillion stars, they’re powered by supermassive black holes… and until 2023 we had no idea how they came into existence. These are quasars, awesomely powerful cosmic objects at the centre of some of the most violent events in the universe. What exactly are quasars, and just how powerful can they be? Dr Vicky Fawcett, Research Associate in Astrophysics at Newcastle University, explains the power of the quasar to amazed space cadet Luke Turner. •“A Quasar can be about a thousand times more powerful than the Milky Way Galaxy itself.” - Dr Vicky Fawcett •“Quasar stands for quasi stellar radio source, because back in the 1960s when they were first discovered, they thought they were radio bright stars.” - Dr Vicky Fawcett •"The central point of a quasar is so bright that they outshine all the stars in the galaxy.” - Dr Vicky Fawcett WHY? is written and presented by Luke Turner.

How can I control my dreams?

How can I control my dreams?

If you could control your dreams, what would you do while you slept? Fly? Get romantic with some unattainable object of desire? Or embark on a fantasy odyssey with no equivalent in reality? Lucid dreams – where we know we’re dreaming and we can control what we do – come to many of us at some point in our lives. But can we learn how to do it? And does lucid dreaming have real-world benefits beyond just being loads of fun? Olly Mann talks to Mark Blagrove, Professor of Psychology and Director of the Sleep Lab at Swansea University, all about the science of lucid dreaming. • “Lucid dreaming gives you something quite extraordinary to think about. It can increase your level of awe at what is possible in the world.” - Mark Blagrove • "People who frequently lucid dream have an ‘internal locus of control’, meaning that they feel in charge of their own life, as opposed to feeling that their life is under the control of chance.” - Mark Blagrove WHY? is written and presented by Olly Mann.

Why can't we predict earthquakes?

Why can't we predict earthquakes?

Without warning a 7.6 magnitude earthquake shook Japan on New Year’s Day, raising the sea floor above the water and causing devastating damage and death. Even with all humanity’s deep scientific knowledge and discoveries, we still cannot predict when an earthquake will strike. Why is that? What mysteries do the earth’s tectonic plates hold, and are we getting closer to solving them?

Can I trust my own eyes?

Can I trust my own eyes?

Your eyes are your window to the world – but is what they’re seeing actually happening? When you’re driving at speed, being alert to the traffic around you will save your life. When a truck in front brakes sharply you have milliseconds to respond, but what if you’re seeing the past? Can your brain process the information it’s receiving quickly enough to avoid catastrophe? Or does it do something completely different and take a leap of faith to predict reality?

Can I programme love with a pill?

Can I programme love with a pill?

If you could take a pill that would make you fall deeply in love with someone, would you do it? And if you could give someone a pill that would make them love you… would that be right? Therapists have been giving couples psychedelic drugs for over 50 years to help build emotional bridges – but can a mere chemical create something as complex as love, from nothing? Dr. Brian D.Earp tells Luke Turner how therapists could use serotonin-inducing drugs to reroute neural pathways, and why a chemically-based relationship would be ethically messy to say the least.

Could tiny robots stop the antibiotics apocalypse?

Could tiny robots stop the antibiotics apocalypse?

The antibiotics that have saved humanity from extinction again and again are about to stop working. Antibiotic-resistant bacteria are multiplying faster than science can keep up. It’s estimated that these pathogens will kill 10 million of us a year by 2050 if we don’t come up with effective treatment. Enter Dr Ana L. Santos of Rice University, Texas. Her team of microbiologists have developed microscopic robots which kill the bacteria that medicine can’t.

Why do I make bad decisions?

Why do I make bad decisions?

Our brains process over 35,000 conscious decisions every day – and let’s face it, they can’t all be good choices. So why do we make bad decisions? Which part of our brain is in control when we decide what to do? How do we decide what’s risky but worth a try? How do we process all this vast information? And why do different people make wildly different choices when faced with the same situations?

Brain implants have moved from science fiction to science fact thanks to innovative research into treatments for neurological illnesses. But could you physically join your brain with an artificial intelligence? What would having a part-machine mind do to your thoughts and your sense of self? Who would be in control?

Are we still evolving?

Are we still evolving?

Our bodies are astonishing in all their beautiful, biological complexity – but do you ever wonder if this is as far as the human form can develop? Millions of years of evolution have created a four-limbed, bipedal mammal with opposable thumbs and a powerful, versatile brain. But have we stopped evolving? Are we still subject to natural selection in the unnatural, man-made world we’ve created? And which genetic mutations will thrive, ensuring the continued survival of our species? Evolutionary biologist Dr. Nicholas Longrich joins Anna Machin to predict how and why humans will evolve in the future… and whether we will eventually transform into an entirely new species.
