Why dolphin poo is being scooped out of West Wales waters

The 200-or-so bottlenose dolphins who frequent Cardigan Bay are the focus of an innovative research project.
Collecting of the dolphins' poo will give valuable clues about their diet and behaviour.
The samples are being collected by researchers from the Wildlife Trust of South and West Wales before analysis by scientists at Aberystwyth University.
They are using the latest environmental DNA (eDNA) techniques to extract detailed data on the animals' diet.

As well as showing what prey the dolphins have been feeding on and where, the tests will help build individual profiles for each one.
These profiles will enable the project team to identify the dolphins' gender, the relationships between family members, population size, breeding potential and movement patterns.
They will also attempt to match and compare each unique profile with individual photo ID records of bottlenose dolphins which have been gathered by the Wildlife Trust of South and West Wales over several years.
The new information will inform future marine conservation efforts in Cardigan Bay and help protect the area's rare population of semi-resident dolphins.
The 'Dolphin Diet Detectives: Unveiling Dolphin Diets and Engaging Communities for UK Conservation' project is being led by the Wildlife Trust of South and West Wales in collaboration with Aberystwyth University, with support from the Welsh Government's Nature Networks Fund.

(Image: Aberystwyth University) Dr Sarah Perry, Marine Conservation and Research Manager at the Wildlife Trust of South and West Wales said: "We are thrilled to be leading this groundbreaking project, which covers an area of research that we have aspired to embark on over the past decade or so.
'We are excited that it has come to fruition at a time when it is even more important that we build on our knowledge of the species in the waters around us.
As part of the project, a series of community science days will give local people opportunities to find out more about the research study and help collect additional data about Cardigan Bay's dolphin population.

Dr David Wilcockson from the Department of the Life Sciences at Aberystwyth University said:
'What is really exciting for us, aside from finding out more about what dolphins are eating and their behaviours, is the fact that we are involving the public in this work.
'They are the 'dolphin detectives' and we hope this will provide another pathway by which they can feel more connected to their local environment and encourage conservation activities beyond the project.'
The project is funded by the Nature Networks Programme. It is being delivered by the Heritage Fund, on behalf of the Welsh Government.

Llusern Scientific Speeding Up Infection Diagnosis with Welsh Innovation Support

Llusern Scientific is developing rapid diagnostic tests to transform how urinary tract infections are diagnosed and treated. With targeted support from the Welsh Government's Innovation team, the company, which is based at Cardiff Edge Business Park, is bringing its first product to market. It is set to pave the way for faster diagnosis, better patient outcomes and reduced antibiotic misuse. Established in 2020 as a spin-out from the University of South Wales, the company set out to address a major health challenge. Urinary infections affect more than 100 million people worldwide each year. Its portable, easy-to-use molecular diagnostic device delivers accurate results within 35 minutes, giving clinicians fast and reliable information. The company has now announced that it has been awarded ISO 13485 certification for its Lodestar DX testing system, a rapid molecular diagnostic platform for urinary tract infections (UTIs). Dr Emma Hayhurst, co-founder and CEO of Llusern Scientific, said: 'When we founded Llusern Scientific, we were on a mission to make a positive difference in healthcare by developing a point-of-care diagnostic that would enable us to improve antimicrobial stewardship. Achieving ISO 13485 certification is a major milestone in our mission because it demonstrates that we have built a manufacturing facility to world-class standards. 'Not only does our Lodestar UTI testing system help a clinician decide whether or not to prescribe an antibiotic, but it will also identify the bacterial cause of the UTI. This enables clinicians to quickly target the right bug with the right treatment to save lives. Now we have ISO 13485 certification, our next goal is to achieve IVDR certification to further expand the market potential for our innovative molecular diagnostic globally.' There are more than 400 million UTI cases globally each year, of which around 90% are women. According to the Sepsis Trust approximately 15-30% of sepsis cases are caused by a UTI. Research has shown that antibiotics are overprescribed by as much as two times for UTIs leading to them being a major driver of antimicrobial resistance (AMR). As well as providing guidance on the best treatment option, Lodestar DX also provides a clear 'rule-out' decision where antibiotics are not necessary, helping to reduce AMR through antibiotic stewardship. ISO 13485 certification is a crucial regulatory step for marketing medical devices globally, as it demonstrates that a manufacturer has a robust Quality Management System in place, showing commitment to patient safety, regulatory compliance, and consistent product quality. Llusern is preparing for commercial launches across India and the Middle East and North Africa region this year, and the US in 2026. The company has received a range of targeted support from the Welsh Government's Innovation team, including SMART Flexible Innovation Support (SFIS), expert design assistance and intellectual property (IP) strategy development—each playing a vital role in advancing the technology and preparing for commercial scale-up. Initial SFIS support in early 2024 enabled the team to develop a clear innovation plan, setting out priorities for product improvements, new clinical applications and growth. A second SFIS award in September 2024 has since supported the delivery of this plan, while design and IP interventions have strengthened its route to market. As a result, Welsh Government innovation support has helped Llusern Scientific to: Enhance its existing diagnostic platform, making it suitable for use in a wider range of clinical settings. Develop a new unique test panel design, addressing contamination risks and improving ease of use for non-laboratory settings. Strengthen its IP portfolio through a comprehensive audit and actionable recommendations, boosting investor confidence. Expand research and development facilities at Cardiff Edge Business Park. Advance collaborations with Public Health Wales and NHS partners, supporting clinical validation and real-world evidence generation. While Agile Cymru funding has provided valuable opportunities to explore international markets, the company's core innovation progress has been driven by targeted support from the Welsh Government's Innovation team.

Survival of the swift in north Powys project begins

A NEW project called 'Screams and Streams' is investigating the relationship between river water quality and the survival of the common swift in northern Powys. It is being led by community groups with support from the Dyfi Biosphere and academic mentors. The project, which runs for four months over the summer, is funded by the Local Policy Innovation Partnerships (LPIPs) project in which Aberystwyth University is a partner. 'Screams and Streams aims to bridge the gap between academic research, communities and policy makers,' explains James Cass, from the Dyfi Biosphere. 'We are pleased to be working with groups from the community and building new relationships between Lab Dŵr Dyffryn Dyfi and Dyfi Swifts, as well as the New Dovey Fishery Association.' Volunteers will be performing regular water tests at 10 set points along the river as well as monitoring swifts across the Dyfi catchment. They will be asking the research question: 'Is there a clear relationship between river health and common swift survival?' The project kicked off with a training evening at the Centre for Alternative Technology near Machynlleth on May 20, with over 25 enthusiastic individuals. Conservationist Ben Porter spoke about the impressive annual migration of the common swift, how to identify them, and why they are threatened. The project will be estimating populations, studying their feeding behaviours and see what use they are making of nest boxes. Jenny Lampard, of Lab Dŵr Dyffryn Dyfi, then gave a demonstration of water testing before a hands-on session where participants practised using equipment and recording data. The event wrapped up with a trip to Ceinws, where the group grabbed a drink and got to watch the local swift population at sunset. 'We are keen to hear from anyone who would like to get involved with the project, whether you're interested in water testing or swifts,' said Bryn Hall, project coordinator. 'We'll give you training and you'll be making an important contribution to our knowledge of wildlife in the biosphere.' Bryn can be contacted on bryn@
