Our bodies are filled with bacteria that have rich social lives and, just like people, these microbial neighbours and families do not always get along. In some cases, it is the bacterial equivalent of The Sopranos. Dr Sally Le Page delves into the bacterial dramas of loners, crowd-lovers, backstabbers and do-gooders that are fighting it out in the world and inside our bodies. Co-operation, cheating and selfish behaviour can all lead to benefits or disease so scientists are studying this behaviour to help produce new medicines and clean up our environment.

Running a restaurant is hard. Long hours, tight margins and constant stress. In this episode of the Food Chain, Rumella Dasgupta travels to Edinburgh, Scotland, to meet Lisa He and her mum Sophie. Lisa has just put her life and acting career on hold, to try and help her mum save the family's restaurant, the China Star. A video she made documenting her attempt has gone viral, with more than fifteen million views. But is a viral video going to be enough to turn a failing business into a success? Lisa's got to fix the sprawling menu, digitise the paper ordering system and cut costs. Lisa and Rumella meet restaurant turnaround expert David Hopkins from the Fifteen Group in Canada, who's on hand to give advice and to explain why restaurants are such difficult businesses to run. Meanwhile the Mand family in Sydney Australia know only too well what Lisa and Sophie are going through. Last year, son Bhav documented his fight to save his dad's failing restaurant. So how's it doing now? And, in such a difficult industry, when is the right time to walk away? Rumella hears from Carleigh Bond, who made the tough decision to close her vegan fast-food restaurant Forked Up in October 2025.

Switzerland recently voted on a radical and unprecedented initiative: capping the country’s population to limit migration. It is the latest in a series of referendums around immigration policy in Switzerland, which have spanned decades. In the weeks preceding the vote, Josephine Casserly was in Switzerland to speaking to the people championing this policy to understand why concerns about immigration have grown so strong in this small, wealthy country, famed for its neutrality.

In the Studio enters the creative world of award-winning Irish-language poet Ailbhe Ní Ghearbhuigh as she composes a new poem. We follow its journey from first draft to first public reading. Ailbhe writes exclusively in Irish. She is deeply rooted in the language’s literary tradition yet unmistakably modern in outlook and has become one of the most distinctive literary voices of her generation. Working from the early-morning quiet of her kitchen table in Cork, the documentary centres on a new triptych inspired by her nine-year-old daughter’s fascination with Greek mythology. Ailbhe takes Dualtagh Herr behind the scenes of her new work, reflecting on childhood imagination, motherhood, and the creative process.
