The Future of Meat - Prof. Hanna Tuomisto - #24

The Ultimate Case for Nuclear Energy - Prof. Wade Allison - #32

Wade Allison is an Emeritus Professor of Physics at the University of Oxford and a Fellow of Keble College, where he taught physics and medical physics for over 40 years. He was inspired at the age of 13 in 1954 after stumbling upon the Atoms for Peace exhibition in Geneva, and went on to study at Cambridge and earn his doctorate in particle physics at Oxford and CERN. His research spanned experimental and theoretical physics, but a final-year course he created on the applications of nuclear physics drew him toward radiation safety, where he became convinced that public fear of radiation is wildly out of proportion to the actual risk. He argues that the blast, fire, fear, and panic surrounding nuclear accidents have caused far more harm than the radiation itself, pointing to the survivors of Hiroshima and Nagasaki, the cleanup of Chernobyl, and the panic evacuation at Fukushima as evidence. He is the author of Radiation and Reason and Nuclear is for Life, and the Honorary Secretary of Supporters of Nuclear Energy. Expect to learn what nuclear energy actually is and how it works, what the three things are that happen when radiation hits living tissue, why the linear no threshold model used to set safety rules is wrong, what really happened to the radium girls who painted glowing watch dials, how a lifetime radiation experiment on dogs revealed a safe threshold, why the fear of radiation was deliberately exaggerated after the war, what the precautionary principle gets wrong, whether a serious nuclear accident could still happen today, why fear and panic do more damage than radiation, how the placebo and nocebo effects can make people genuinely ill, what the Goiania accident in Brazil teaches us, what radiation did and did not do to the survivors of Hiroshima and Nagasaki, why nuclear fuel holds a million times more energy than fossil fuels, and whether nuclear power is really as expensive as people believe.

The Ethics of Mining the Moon - Dr. Erik Persson - #31

Erik Persson is a Swedish philosopher, an Associate Professor in the Department of Philosophy at Lund University and co-director of its Space Humanities Lab, where his work focuses on the ethics of space exploration. He wrote his doctoral dissertation in environmental ethics and has also studied astrobiology and astronomy, which led him to ask whether the principles we apply to the environment here on Earth can be extended beyond it. His research deals with the moral questions raised by asteroid and lunar mining, planetary protection, terraforming, and the long-term settlement of Mars, and he has published widely on the conflicts between commercial use of space, science, and the possible value of extraterrestrial life. In this conversation he traces how space mining moved from science fiction into a serious geopolitical contest, now that the Artemis programme and a renewed race to the Moon have brought celestial resources within reach. He helps organize a biennial space ethics conference, the most recent edition of which took place at Carnegie Mellon University, with the next planned for Padua, Italy. Expect to learn what space mining actually means and how mining an asteroid differs from mining the Moon or Mars, why bringing resources back to Earth is rarely worth the energy, how the Artemis programme and China's lunar ambitions have reignited the space race, what the Outer Space Treaty and the Artemis Accords do and do not allow, whether a first come first served approach to space resources is fair, how mining in space could either narrow or widen the gap between rich and poor, what planetary protection is and why we sterilize spacecraft, whether it could ever be ethical to terraform a planet, what we owe to extraterrestrial life if we find it, whether it is right to raise children who never chose to be born on Mars, and why some argue for human settlement of space even when it benefits no one alive today.

The Surprising Rebirth of Belief in God - Justin Brierley - #30

Justin Brierley is a British writer, broadcaster and public speaker who has spent over two decades hosting dialogue between Christians, atheists and sceptics. After university he joined Premier Christian Radio in London, where he spent more than twenty years and became known for Unbelievable, a weekly faith debate show that brought believers and non-believers together to argue the big questions. Going freelance in 2023, he now hosts the Re-enchanting podcast and the dialogue show Uncommon Ground, alongside his documentary series The Surprising Rebirth of Belief in God. His central argument is that, after the heyday of New Atheism, secular thinkers across the West are taking Christianity seriously again, a cultural turn he traces through declining birth rates, the search for meaning, and a fresh openness among public intellectuals. His book of the same name, The Surprising Rebirth of Belief in God, lays out the case in full. Expect to learn how Justin moved from Christian radio into hosting debates between believers and atheists, what New Atheism was and why its momentum faded, how figures like Jordan Peterson and Tom Holland shifted the public conversation, why the decline of religion may be linked to falling birth rates and a loss of community, what Christianity offers people searching for meaning and purpose, how the idea of grace differs from a culture of constant striving, whether the so-called revival is real or just an online algorithm, what the controversy over the withdrawn Bible Society survey actually shows, how cultural Christianity differs from genuine belief, what Blaise Pascal meant by making people wish Christianity were true, why Justin thinks you cannot understand faith from the outside, and how to begin exploring Christianity if you are open but not yet convinced.

The Science of Slang and Swearing - Prof. Kate Burridge - #29

Kate Burridge is Professor of Linguistics at Monash University in Melbourne, Australia, and a Fellow of both the Australian Academy of the Humanities and the Academy of Social Sciences in Australia. She earned her PhD from the University of London in 1983 with a dissertation on syntactic change in medieval Dutch. Burridge has authored or co-authored more than 25 books on language, including Blooming English, Weeds in the Garden of Words, and Forbidden Words: Taboo and the Censoring of Language. She is a regular presenter of language segments on ABC Radio and co-hosts the Breaking Taboos podcast, which explores how older people talk about mental health. In this conversation, she explains how slang is born and dies, why swearing provides genuine physical relief, and what makes some words taboo in one era but perfectly acceptable in another. Expect to learn how medieval Dutch surgery manuals reveal patterns of language change, why 800 separate languages exist in Papua New Guinea, what linguistic accommodation is and why we do it instinctively, how swearing in your first language provides greater emotional release, why the ice water experiment proved that swearing increases pain tolerance, how slang got its start as underworld criminal jargon, why 30% of English words for stupidity begin with the letter D, how social media accelerates the birth and death of slang, what makes OK the most successful slang term of all time, how disease-based swearing works in Dutch, and why euphemisms around mental health can delay treatment for older people.

Can We Upload The Human Brain? - Dr. Randal Koene - #28

Randal Koene is a Dutch neuroscientist, neuroengineer, and co-founder of the Carboncopies Foundation, a nonprofit advancing research into substrate-independent minds. He holds a Ph.D. in Computational Neuroscience from McGill University and an M.Sc [http://M.Sc]. in Electrical Engineering from Delft University of Technology. Koene coined the term "whole brain emulation" in 2000 and has spent decades building the scientific roadmap for recreating brain function in non-biological substrates. He previously served as a professor at Boston University's Center for Memory and Brain, as Director of Neuroengineering at Tecnalia in Spain, and as Science Director of the 2045 Initiative. In this conversation, he explains how structural brain scanning has advanced dramatically, why the viral fruit fly brain demo was more limited than headlines suggested, and what it would actually take to build and validate an emulation of a human brain. Expect to learn how Randal's father at CERN shaped his thinking about substrate independence, what inspired him to coin the term whole brain emulation, how lesion studies and evolutionary biology support the idea that minds can run on different hardware, what the difference is between neuronal networks and artificial neural networks, how electron microscopy is transforming brain data collection, why the viral fruit fly brain demo was misleading, what the two biggest bottlenecks are in scaling brain emulation to humans, how AI is being used as a tool in computational neuroscience, what consciousness is according to the Metzinger framework, whether a brain emulation would have human rights, how the Carboncopies Foundation's brain emulation challenge works, and why whole brain emulation and mind uploading are not the same thing.
