    Have I ever been in an experiment?

    Have you ever been part of an experiment? Maybe you have, without even realising it. In fact, you almost certainly have. When most people think of experiments, they imagine laboratories, test tubes and volunteers following carefully designed instructions. But sometimes scientists can learn just as much from real-world events over which they have no control. In this episode of Talking of Science, Dr C and Helen are joined by health economist and researcher Frederik Plesner Lyngse to explore the fascinating world of natural experiments. From tracking the spread of COVID-19 between households to studying a Danish lottery that determines where newly qualified doctors begin their careers, Frederik explains how researchers use real-life situations to answer questions that could never be investigated through conventional experiments. Along the way, we discover how evidence from natural experiments can help policymakers make difficult decisions when there is no perfect solution. Expect pandemics, minks, statistics, politicians, randomisation, rural hospitals, personal data archives, career-defining lotteries, and some surprisingly deep discussion about whether dividing a chocolate scone equally between two siblings is always the fairest option. Along the way, Dr C challenges a few economic assumptions, wonders whether politicians have something to do with pollen, and discovers that chance plays a bigger role in our lives than we might like to think.

    How can intelligence be artificial?

    Artificial intelligence is not new. In fact, its origins go back to ideas that emerged even before the first modern computers. But what we have today seems nothing short of magical. AI chatbots can answer questions, write stories, help doctors detect diseases, perform a wide range of tasks, and even suggest what you should have for dinner. But do they actually understand what they're saying? Or are they simply recognising patterns and generating responses that sound convincingly human? In this episode of Talking of Science, Helen and Dr C are joined by machine learning engineer Kübra Altinel to unpack one of the biggest technological questions of our time: How can intelligence be artificial? Together, they explore what AI actually is, how chatbots like ChatGPT generate answers, why they sometimes "hallucinate" information, and what makes them seem so convincingly human. Along the way, Kübra explains why AI is less like a person who understands the world and more like someone who has read millions of books but never stepped out of their home. The conversation also explores how AI is already helping scientists and doctors, why probability lies at the heart of every chatbot response, and why healthy scepticism is one of the most important skills we can develop as AI becomes part of everyday life. As always, Dr C's curiosity steers the discussion into unexpected places, proving that any complex topic can be understood through simple examples and analogies involving cakes, cookies, phone books, and grandmas.
