Series 11 starts Mon 10th November 2025!
RTÉ’s award-winning science series is back, taking a deep dive into some of the challenges facing us in Ireland today and showing how Irish research is striving to provide solutions. Presented by Kathriona Devereux, Amy Hassett and Fergus McAuliffe, the six-part series shines a light on the science that shapes and connects us all — from our health and homes to the planet we share.
This season, we ask why change is so difficult, even when we want it, and explore how individuals and communities are making changes to reimagine our farms and towns. We dig deep into the materials and technologies behind how we build, from the gypsum mines of Monaghan to the craftspeople preserving Ireland’s architectural heritage. As Ireland faces more frequent and powerful storms, the series investigates the science of extreme weather and the efforts to protect forests and coastal communities. We also examine the growing threat of invasive species — from Asian hornets to aquatic invaders – and meet the scientists developing new technologies to safeguard biodiversity. From the limestone landscapes of the Burren to the depths of the Atlantic, the story of carbon reveals how this vital element connects life, geology, and climate. Finally, the series explores the hidden world of bacteria and the urgent fight against antibiotic resistance through groundbreaking research and collaboration.
With thought-provoking stories and a dash of curiosity, 10 Things to Know About… continues to reveal the important research happening on our doorstep and how it’s changing our future.
Produced by New Decade and proudly supported by Geological Survey Ireland, Met Éireann, Research Ireland and Teagasc, 10 Things to Know About… returns Monday 10th November at 8.30pm on RTÉ One and RTÉ Player.
