Archaea
Misha Glenny and guests discuss one of the most remarkable scientific discoveries of the 20th century: the archaea microorganisms. In the 1970s the American microbiologist Carl Woese (1928-2012) realised that the tiny bacteria-sized organisms he was studying were not actually bacteria but from an entirely different branch of the tree of life. It became clear that archaea, as he named them, share aspects of the cells in all plants and animals even if they often live in places where other life struggles including salty lakes, acidic pools, under the sea bed and in the gut. While aspects of what followed from Woese are still under debate, further discoveries suggest that life on Earth has been on a journey of separation and reunion: that the first cells developed into bacteria and archaea billions of years ago and that some of those later combined to form the complex cells from which we are made.

Collagen (2026 update)
What's the latest on Collagen?The new series of Sliced Bread kicks off with an update on one of the wonder products most-requested by listeners. Presenter Greg Foot first looked at Collagen in 2022 and returns to the subject to find out what has changed in the scientific landscape since then. Could there be new evidence that it really can do what the manufacturers claim: rejuvenate skin, nails and hair - and even help with joint and bone health? To find out, Greg is rejoined by the expert from that original episode four years ago, dermatologist Dr Emma Wedgeworth, alongside Professor Jayne Tierney from University College London who specialises in reviewing evidence.Together they do a deep-dive on the latest science, including a new study from one of the brands featured in 2022, Absolute Collagen. Does it stand up to scrutiny?If you’ve seen an ad, trend or wonder product promising to make you happier, healthier or greener, email us at sliced.bread@bbc.co.uk or send a voice note to our WhatsApp number, 07543 306807.RESEARCHER: PHIL SANSOMPRODUCERS: PHIL SANSOM AND GREG FOOT
09/04/26 C02 plant back up and running, planting in a bog, oilseed rape
Farmers in the North East of England have welcomed the re-opening of the UK’s only carbon dioxide production plant after 6 months of inactivity. It was mothballed last year, after the US trade deal made it unprofitable. But the war in the Middle East has led to government concerns about CO2 shortages, and they’ve awarded a £100 million pound grant to the Ensus bioethanol factory at Redcar to re-start production. Paludiculture is the practice of farming on wetlands, like bogs or re-wetted peatlands and fens. Defra awarded grants to 12 projects to look at growing crops in lowland peat; the UK’s peatlands store 3 billion tonnes of carbon and keeping peat wet means locking it in the earth, so it’s not lost as C02 contributing to global warming. The Holker Estate on the southern coast of Cumbria is one of those exploring the potential of paludiculture.And oilseed rape is having a good year.Presented by Caz Graham and produced by Beatrice Fenton.
Can the US-Iran truce survive?
Both Iran and the US declare victory as the ceasefire approaches its 24th hour, but can the truce survive?

A new gig theatre production at The Mac in Belfast honours the Women's Coalition in Northern Ireland whose activism was an important force behind the 1998 Good Friday Agreement. Writer Vittoria Cafolla joins us to tell us their story. And as we go on air, the winners of this year's Windham-Campbell Awards for writing are announced. Each recipient receives $175,000, and we'll hear from one of the winners, as well as the Director who heads up the judging panel. Presenter: Kirsty Wark Producer: Mark Crossan
