10 Things To Know About

Season 11: Episode 4 – Invasive Species

RTÉ’s award-winning science series 10 Things To Know About… 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.

Each week, we meet the researchers and communities working at the coalface of science and
innovation, revealing how Irish scientists are tackling some of the world’s most pressing
problems.

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 ground-breaking 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.

Episode 4 – Invasive Species

Earlier this year, the discovery of Asian Hornets in Cork made headline news and sparked nationwide conversations about the significant threat invasive species pose to Ireland. They can alter ecosystems and habitats, disrupt natural processes, and some introduce diseases that can have catastrophic impacts on nature, wildlife and human health. We have exclusive access to the lab and researcher tasked with the job of freezing, dissecting and analysing the nests to determine the Queen’s DNA origins, we literally look into the hornets’ nest and discuss the potential implications for Ireland’s pollinators. Invasive insects can damage and destroy crops and one of the worst offenders across Europe is the stink bug, which is particularly problematic for tree fruits like pears and apples. For producers, insect and pest monitoring is critical, but traditional methods are time-consuming and labour intensive. We meet the researchers working to automate and accelerate the pest identification process, protect food systems and keep the smell of the stink bug out of Ireland. On Lough Neagh, millions of invasive zebra mussels are disrupting the food web and unintentionally promoting toxic algal blooms that threaten wildlife, pets and humans. We investigate the latest technology being developed to monitor these contaminants and improve early detection to make our lakes and watercourses safer for all. Meanwhile in Curious Chronicles, Fergus charts the rise of the rabbits that inadvertently led to a full-scale war on a beloved national icon of Australia

Fergus McAuliffe has a PhD in Environmental Science and is an award-winning science communicator. As Communications and Public Engagement Manager at Ireland’s Research Centre in Applied Geoscience he worked closely with researchers, artists, teachers and the media, and he has recently taken on the role as
the Head of Research Engagement and Impact at Trinity College Dublin. He has been part of the 10 Things team since its inception, writing and presenting short, quirky stories for his own segment titled “Weird Science”. Over the years, he has worked with the producers to evolve this segment to incorporate intriguing tales connecting science with arts and literature which he now presents as “Curious Chronicles”. In 2025, Fergus joined Kathriona and Amy as part of the main 10 Things presenting team and he has thoroughly enjoyed meeting the researchers and members of the public and looks forward to discussing their work on our tv screens.
