04 | Artificial Evolution: Pig Parts for People?

Timothy Andrews has lived with a pig kidney in his body for eight months.That makes him a record breaker — living longer with a gene-edited pig kidney than anyone else in the world so far.In the final episode of Artificial Evolution, he tells us about his journey, his hopes for making it a year with the transplant, and the challenges he's faced along the way.With expanded clinical trials into this 'xenotransplantation' around the corner, researchers and advocacy groups argue a future in which animal organs are used in life-saving transplantation procedures for humans is not far off.So what is the science and history of xenotransplantation? What are the ethical concerns? And what's happening in Australia?You can hear more episodes of Science Friction with journalist Peter de Kruijff about DNA, cloning, genetic modification and gene editing on the ABC listen app (Australia) or wherever you get your podcasts.Guests:Timothy AndrewsNew Hampshire, United StatesProfessor Wayne HawthorneProfessor of Transplantation, Westmead HospitalProfessor Dominique MartinProfessor of Health Ethics and Professionalism, Deakin UniversityProfessor Syd JohnsonProfessor of Bioethics, Upstate Medical University, Syracuse, New YorkCredits:Presenter: Peter de KruijffProducer: Fiona PepperSenior Producer: James BullenSound Engineer: Tim SymondsArchives Researcher: Lisa ChidlowThis story was made on the lands of the Gadigal, Whadjuk Noongar and Menang Noongar peoples.

02 | Artificial Evolution: Genetically Modified Marsupials

Earlier this year, a US biotech company claimed it had brought back a long-extinct species - the dire wolf, which roamed ancient America thousands of years ago.And the same editing technology that remade dire wolves could also be used to stop Australian species from going extinct.In episode two of Artificial Evolution, Pete heads to the labs that are safeguarding the genetic material of unique Australian species and working to bring back the thylacine.And visits the researchers working on quolls to make them immune to cane toad toxins and experimenting with putting alpaca genes into endangered frogs to protect them from a deadly fungal disease.As this new field of science opens up opportunities to edit endangered species … can and should we act? And do we have our priorities wrong in tackling species loss and climate change?Artificial Evolution is a four-part series from Science Friction about how gene technologies are changing the world around us.You can hear more episodes of Science Friction with journalist Peter de Kruijff about DNA, cloning, genetic modification and gene editing on the ABC listen app (Australia) or wherever you get your podcasts.Credits:Presenter: Peter de KruijffProducer: Fiona PepperSenior Producer: James BullenSound Engineer: Angie GrantArchives Researcher: Lisa ChidlowThis story was made on the lands of the Gadigal, Whadjuk Noongar and Menang Noongar peoples.

02 | Brain Rot: Is AI turning us off human relationships?

Whether it’s social media, the omnipresent smartphone or AI companions, in recent decades the way we relate to each other has been completely up-ended. In episode two of Brain Rot, we explore the potential implications that tech poses to human relationships. Worldwide estimates suggest there are around one billion users of AI companion — people using software or applications designed to simulate human-like interactions through text and voice. So if the uptake of these AI companions is as rapid as is being reported, what are the ramifications? And could AI companions be both a cause and cure for loneliness? Brain Rot is a new five part series from the ABC’s Science Friction about how tech is changing our brains, hosted by Ange Lavoipierre. Guests:KellyIn a relationship with an AI companion, ChristianBethanie Drake-MaplesDoctoral Candidate, Research Fellow, Stanford Institute for Human-Centred Artificial IntelligenceNicholas EpleyProfessor of Behavioural Science, University of Chicago Booth School of BusinessNicholas CarrAuthor and journalistCredits:Presenter: Ange LavoipierreProducer: Fiona PepperSenior Producer: James BullenSound Engineer: Tim SymondsThis story was made on the lands of the Gadigal and Menang Noongar peoples.

05 | Cooked: Electrolytes — who needs them?

Over the past few years, you might have heard advertisements in your podcast feed or on social media for electrolyte supplements.If you haven’t seen them, they’re basically these little sachets or tubs that get mixed in with water as a drink.News media reports demand for such products is exploding – with the market for electrolyte supplements set to grow to 112 billion dollars by 2030, more than doubling in size in less than a decade.They go by a bunch of different names … and their marketing often suggests we could all use more electrolytes in our life.But what’s the science on this swing towards salty beverages? Who actually needs them? And what does our obsession with optimised hydration … say about us?Guests:Dr Alan McCubbinSenior Teaching Fellow, Department of Nutrition Dietetics and Food, Monash University; Accredited Sports DietitianDr Colleen DerkatchProfessor of Rhetoric, English Department, Toronto Metropolitan University; Author, Why Wellness SellsJay ClarkAthlete and fitness coachDan NewtonAthlete and fitness coachCredits:Presenter: Dr Emma BeckettProducer: Carl SmithSenior Producer: James BullenSound Engineer: Tim JenkinsThis story was made on the lands of the Gadigal, Wurundjeri, Jagera and Turrbal peoples.More information:Modelling sodium requirements of athletes across a variety of exercise scenarios – Identifying when to test and target, or season to taste - European Journal of Sport Science, 2022.The Impact of Dietary Sodium Intake on Sweat Sodium Concentration in Response to Endurance Exercise: A Systematic Review - International Journal of Sports Science, 2018.Impact of Sodium Ingestion During Exercise on Endurance Performance: A Systematic Review - International Journal of Sports Science, 2018.Sodium Intake Beliefs, Information Sources, and Intended Practices of Endurance Athletes Before and During Exercise - International Journal of Sport Nutrition and Exercise Metabolism, 2018.Sports Dietitians Australia Position Statement: Nutrition for Exercise in Hot Environments.Why Wellness Sells - Hopkins Press, 2022.Exercise - the low down on hydration - Better Health.The electrolytes boom: a wonder supplement – or an unnecessary expense?

02 | Cooked: All-meat eaters say they feel great - but why?

Diets like carnivore have been popping up all over the place. People who go carnivore aim to eat nothing but a select few animal products, like meat and eggs.So why are some people turning to an all-meat diet? And why do they say they feel good doing so?On this episode of Cooked, we sift through some of the counterintuitive findings around carnivore — the scientific pitfalls you need to be aware of when reading the research — and the health effects in the short and long term.Guests:Mick and JennyNew South Wales, AustraliaDr Jacob MeyAssistant Professor and Registered Dietitian, Pennington Biomedical Research Center, LouisianaDr Richie KirwanLecturer, Nutrition and Exercise Physiology, Liverpool John Moores UniversityDr Janet ChrzanNutritional anthropologist, University of PennsylvaniaAuthor, Anxious Eaters: Why We Fall For Fad DietsCredits:Presenter: Dr Emma BeckettProducer: Carl SmithSenior Producer: James BullenSound Engineer: Angie GrantThis story was made on the lands of the Gadigal, Wurundjeri, Jagera and Turrbal peoples.More information:Behavioral Characteristics and Self-Reported Health Status Among 2029 Adults Consuming a "Carnivore Diet" - Current Developments in Nutrition, 2021.Limitations of Self-Reported Health Status and Metabolic Markers Among Adults Consuming a “Carnivore Diet” - Current Developments in Nutrition, 2022.Fruit and Vegetable Intake and Mortality: Results from Two Prospective Cohort Studies of US Men and Women and a Meta-Analysis of 26 Cohort Studies - Circulation, 2021.Long-Term Consumption of 10 Food Groups and Cardiovascular Mortality: A Systematic Review and Dose Response Meta-Analysis of Prospective Cohort Studies - Advances in Nutrition, 2022.Association of changes in red meat consumption with total and cause specific mortality among US women and men: two prospective cohort studies - BMJ, 2019.Anxious Eaters: Why We Fall For Fad Diets - Columbia University Press, 2022.What is the carnivore diet? - Harvard Health Publishing, 2024.

01 | Cooked: Could ice cream actually be good for you?

Two decades ago, nutritional epidemiologists made a startling finding – that people eating more ice cream were less likely to develop diabetes.In the years since, various groups have tried to account for this peculiar scientific signal — with limited success.In multiple studies the link between ice cream and a reduced risk of diabetes persists. Yet nutrition experts globally still aren’t convinced.But if it’s not true, what’s causing the signal?Grab a spoon and dig into culture, causation and confounders — and the joy of a tub of ice cream.Credits:Presenter: Dr Emma BeckettProducer: Carl SmithSenior Producer: James BullenSound Engineer: Nathan TurnbullThis story was made on the lands of the Gadigal, Jagera and Turrbal peoples.More information:Nutrition Science's Most Preposterous Result - The Atlantic.Here's the scoop on the new thinking about ice cream, yogurt, cheese and health - WBUR.Dairy and your heart health - Heart Foundation.
