Dolphin 'mysteries' to be solved by collecting poo
Conservationists are hoping to learn about a group of bottlenose dolphins that make their home in Welsh waters - by studying their poo.
About 200 bottlenose dolphins are said to live in and around Cardigan Bay and, although they have been studied for several years, experts want to learn more about their relationships, breeding potential and movement patterns.
Analysis of samples will help them to understand what they have been feeding on and where and help build individual profiles for each dolphin.
They will also attempt to match the samples with photo identification records of the dolphins gathered on camera by members of the Wildlife Trust of South and West Wales.

The trust secured funding for the project from the Welsh government's Nature Networks Fund in collaboration with Aberystwyth University.
The samples will be gathered by net after the dolphins defecate and then analysed by university scientists using techniques to extract detailed data about the animals' diet using environmental DNA (eDNA).
Sarah Perry, the trust's marine conservation and research manager, said she hoped the study would "unravel the mysteries of bottlenose dolphin ecology in Cardigan Bay".
"This project covers an area of research that we have aspired to embark on over the past decade or so and 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."

This expanded agreement provides the Welsh Government with Planet's high-resolution SkySat tasking capabilities, PlanetScope near-daily global satellite imagery and historical archive, and the company's analysis-ready Planet Fusion data. Through this deal, these products are accessible to all eight universities in Wales, through Campus licenses, to inform novel research and model future landscape scenarios for government policy. The government of Wales has leveraged Planet's satellite data since 2020, and this expansion aims to further develop its existing work, moving from test and trial projects to development of operational systems and use as part of business-as-usual processes. The Welsh government is focused on developing the use of satellite imagery to identify, monitor and understand 'change' in support of priority policy areas including compliance and monitoring, land use, flood, forestry, and water quality management. With Planet's historical archives of high-cadence and high-resolution satellite imagery, the Welsh Government is also evaluating the economic trade-offs of landscape change. 'With our ability to deliver global satellite data on a near-daily basis, Planet is uniquely suited for government-wide monitoring, compliance, and broad area management initiatives,' said Planet President and CFO Ashley Johnson. 'It's really exciting, as we are seeing countries across Europe transform their agricultural lands and increase resource efficiency by integrating our data into their policy plans.' By combining Planet's data with the Welsh government's robust research initiatives, Wales is able to build innovative policy outcomes, to better understand the Welsh environment, to support evidence-based policies now and as part of long-term frameworks for the Wellbeing of Future Generations.

Specific hot drink helps you avoid 11 serious conditions and 'age better'
Women who drink coffee every day age better, according to a new study. Researchers found that women who enjoy three small daily cups of caffeinated coffee in middle age stay sharp, strong and mentally well as they get older. But tea and decaffeinated coffee didn't show the same benefits while colas were "strongly associated" with less healthy ageing, according to the findings of the study that followed thousands of women for 30 years. Study author Dr Sara Mahdavi said: 'While past studies have linked coffee to individual health outcomes, our study is the first to assess coffee's impact across multiple domains of aging over three decades. 'The findings suggest that caffeinated coffee - not tea or decaf - may uniquely support aging trajectories that preserve both mental and physical function."

Chan School of Public Health in the US, and an adjunct professor at the University of Toronto, Canada, said: 'Our study has several key strengths. In addition to the large sample size and 30 years of follow-up, we assessed several different aspects of longevity and healthy aging as well as very comprehensive information on nutritional and lifestyle habits that were collected every four years after the initiation of the study.' The study included 47,513 women with dietary and health data collected since 1984. The research team assessed caffeine intake using questionnaires that included consumption of top contributors of caffeine such as coffee, tea, cola and decaffeinated coffee. Healthy ageing was defined as living to age 70 or older, being free from 11 major chronic diseases, maintaining physical function, having good mental health, and showing no cognitive impairment or memory complaints. After 30 years, the research team estimated how the likelihood of healthy ageing changed for every 80mg of caffeine that the study participants consumed per day. They also examined specific drinks including coffee, tea, decaffeinated coffee, per eight-ounce cup, and cola, per 12-ounce glass. The analysis accounted for other factors that might influence healthy ageing including body weight, smoking, alcohol use, physical activity, education level and protein in the diet. By 2016, 3,706 of the women in the study met all the requirements for being considered healthy agers. In middle age, from 45 to 60, those women typically consumed an average of 315 mg of caffeine per day - about the amount in three small cups of coffee or 1.5 large cups by today's standards. More than 80% of that caffeine came from regular coffee consumption. For women in the healthy agers group, each extra cup of coffee per day was tied to a 2% to 5% higher chance of doing well later in life, up to five small cups per day, or about 2.5 cups according to today's measures. The research team didn't find any significant association between drinking decaffeinated coffee or tea with an increased likelihood of healthy ageing. And each additional small glass of pop - another major source of caffeine - was associated with a 20% to 26% lower likelihood of healthy ageing. The researchers say the findings indicate that not all sources of caffeine confer benefits. Dr Mahdavi said: 'These results, while preliminary, suggest that small, consistent habits can shape long-term health. 'Moderate coffee intake may offer some protective benefits when combined with other healthy behaviours such as regular exercise, a healthy diet and avoiding smoking. While this study adds to prior evidence suggesting coffee intake may be linked with healthy ageing, the benefits from coffee are relatively modest compared to the impact of overall healthy lifestyle habits and warrant further investigation.' The researchers note that, in general, up to two cups of coffee per day should be safe and potentially beneficial for most people. Beyond that, drinking more may offer additional benefits for some - but may not be healthy for others. Dr. Mahdavi and her colleagues have shown in a previous study that genetic variation can influence the relationship between caffeine intake and health outcomes, so more caffeine isn't always better- particularly for people with lower caffeine tolerance or specific genetic susceptibility. The team now plan to investigate how specific bioactive compounds in coffee interact with genetic and metabolic ageing markers, especially in women. They say that understanding those mechanisms could guide personalised medicine approaches to develop diets that support healthy ageing. Dr Mahdavi presented the findings at the annual meeting of the American Society for Nutrition in Orlando, Florida.
