  • Will robot soldiers replace human armies?

    Will robot soldiers replace human armies?
    Apr 4 2024
    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?
    Mar 28 2024
    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?
    Mar 21 2024
    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?
    Mar 14 2024
    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?
    Mar 7 2024
    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?
    Feb 29 2024
    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?
    Feb 22 2024
    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?
    Feb 19 2024
    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.
