Weekly: The truth about Iron Age women; Climate whiplash and the LA wildfires; Rebooting the world’s first chatbot

Episode 285 New archaeological evidence from Iron Age Britain has shaken up long-held beliefs about the role of women in ancient civilisations. By studying the genes of the Durotriges tribe, who lived in Dorset 2000 years ago, researchers have discovered women were the centrepiece of Celtic society - supporting evidence that they had high status across Europe. Rachel Pope, Reader in European Prehistory at the University of Liverpool, explores the “jaw-dropping” findings. We also hear from author and archaeologist Rebecca Wragg-Sykes, who explains why we shouldn’t be surprised that women in prehistory had such power and autonomy. Sudden swings in weather extremes caused by climate change could be to blame for the wildfires spreading across Los Angeles. The effect, known as “climate whiplash”, is becoming increasingly common and has wide-reaching implications, threatening crops, water supplies and more. And with the news that we breached 1.5C of global warming in 2024, we discuss what this all means for our climate goals. The world’s first chatbot, ELIZA, has been resurrected. Created by MIT computer scientist Joseph Weizenbaum in the 1960s, it contains just 420 lines of code and is a very basic precursor to the likes of ChatGPT and Gemini. The team demonstrates its (limited) capabilities live on the show. They also discuss news of a woman who has an AI boyfriend on ChatGPT…that she has sex with. Hosts Rowan Hooper and Penny Sarchet discuss with guests Rachel Pope, Rebecca Wragg-Sykes, James Dinneen and Madeleine Cuff.
