Posted on: 19 December 2025 The team has uncovered that the Irish Cervical Cancer Screening programme has prevented over 5500 cancers in Ireland, that would over wise have occurred in the lifetime of women screened. The outcomes figured by the team give a solid support for the clear efficacy of cervical cancer screening in Ireland and beyond.

A new study has revealed bumblebee workers are getting smaller in areas with high honeybee activity. The research, carried out in the Dublin and Wicklow Mountains, found that managed honeybee colonies can alter the behaviour and physical traits of wild bumblebees, even in flower-rich environments. Publishing their findings in Proceedings of the Royal Society B , researchers from University College Dublin and Lund University examined how different numbers of honeybee hives affected forage availability and bumblebee activity across late summer sites dominated by blooming heather.

Posted on: 04 December 2025 Higher plant diversity in agricultural grasslands increases yields with lower inputs of nitrogen fertiliser. That is the headline finding of a landmark, international study led by Trinity that paints a promising picture for more sustainable agriculture. And in further good news, the research shows that under warmer temperatures, the yield benefits of more diverse grasslands further increase.

Posted on: 02 December 2025 Trinity researchers have led a new collaborative study, combining large genetic datasets with satellite weather data and uncovering over 30 distinct genes that influence vitamin D status, many of which were not previously known. The study involved collaborators from Maynooth University, the Netherlands, UK, Denmark, Austria, and Germany and is published in the journal Nature Communications.

Posted on: 26 November 2025 The scientists have discovered that a single inherited mutation causes whole-body issues in a model of inherited primary mitochondrial disorders after the immune response is sparked into action. Although the scientists stress the research is at a relatively early stage, it is one of the first pieces of work to show that a heritable mitochondrial DNA mutation can independently remodel immune cell function and inflammatory signalling.

Findings have major implications for design, use, and regulation of interactive AI systems Humans bring gender biases to their interactions with Artificial Intelligence (AI), according to new research from Trinity College Dublin and Ludwig-Maximilians Universität (LMU) Munich. The study involving 402 participants found that people exploited female-labelled AI and distrusted male-labelled AI to a comparable extent as they do human partners bearing the same gender labels.

Posted on: 14 November 2025 A comprehensive programme of new research from the Health Research Board (HRB) Collaborative Doctoral Award (CDA) in Multimorbidity has provided crucial insights and evidence-based solutions to improve healthcare and outcomes for people living with multiple long-term conditions (multimorbidity).

Posted on: 13 November 2025 There's no scientific evidence that the gut microbiome causes autism, a group of scientists argue in an opinion paper publishing today in international Cell Press journal Neuron. They say conclusions from past research that supported this hypothesis-including observational studies, mouse models of autism, and human clinical trials-are undermined by flawed assumptions, small sample sizes, and inappropriate statistical methods.

Posted on: 11 November 2025 An international study led by Agustín Ibáñez and co-authors reveals that speaking multiple languages may slow the biological processes of aging and protect against age-related decline. Multilingualism protects against accelerated aging in cross-sectional and longitudinal analyses of 27 European countries Can learning another language help you stay younger for longer?

Posted on: 31 October 2025 Two landmark international studies led by Professor Ignacio Martin-Loeches have been recently published in The Lancet and Nature Medicine - placing Irish critical care research firmly on the global stage.

Posted on: 23 October 2025 Researchers wanted to know what allows the infection to hang on or come back, and whether it develops new tricks or resistances while living inside the lungs. Researchers at Trinity Translational Medicine Institute (TTMI) and the Irish Mycobacterial Reference Laboratory at St James's Hospital have uncovered how the bacterium Mycobacterium avium -a leading cause of difficult-to-treat chronic lung infections -changes and adapts inside patients over many years of illness.

Posted on: 22 October 2025 Researchers from Trinity College, St Patrick's Mental Health Services, Queen's University Belfast, Ireland, investigate use of twice-weekly ketamine infusions as an add-on treatment for inpatients with serious depression Findings from a randomised and blinded clinical trial investigating repeated ketamine infusions for treating depression have revealed no extra benefit for ketamine when added onto standard care for people admitted to hospital for depression.

Posted on: 21 October 2025 This "UTPC" seemingly applies to all species and dictates their responses to temperature change. It essentially "shackles evolution" as no species seem to have broken free from the constraints it imposes on how temperature affects performance. All living things are affected by temperature, but the newly discovered UTPC unifies tens of thousands of seemingly different curves that explain how well "species work" at different temperatures.

Posted on: 09 October 2025 Researchers wanted to understand how steroids selectively affect human macrophages, which are a key cellular player in the immune response to Mycobacterium tuberculosis (Mtb); the bacteria which causes TB. Tuberculosis (TB) remains a major global health challenge, affecting over 10 million people annually worldwide, with 1.25 million people dying of TB every year.

Astronomers have detected the explosive, highly toxic gas phosphine (PH3), in the atmosphere of an ancient brown dwarf (Wolf 1130C) located 54 light-years from the Sun in the constellation Cygnus. Phosphine has long been recognised as a possible biosignature for anaerobic life, given that there are few natural sources in terrestrial planet atmospheres.

Posted on: 03 October 2025 Engaging in creative experiences like music, dance, visual arts, and even specific video games can slow brain aging and promote healthier brain function, says a trailblazing international GBHI study from published in Nature Communications Although creativity has long been celebrated for its cultural and personal value, this study is the first large-scale scientific evidence directly linking creative engagement to direct measurable protection of brain health.

Posted on: 15 September 2025 Scientists from the Trinity Biomedical Sciences Institute (TBSI) have discovered how nanoplastics - even smaller than microplastics - disrupt energy metabolism in brain cells. Their findings may have implications for better understanding neurodegenerative diseases characterised by declining neurological or brain function, and even shed new light on issues with learning and memory.

Posted on: 12 September 2025 Parents report improvements in physical activity, social engagement and family life in their children in the first qualitative assessment of its type led by researchers from Trinity. This study provides important evidence in an area of growing therapeutic interest. Specifically, the parents of 10 children aged 6-12 with neurological and/or physical impairments in their walking perceived improvements in most of the childrens' physical activity levels, as well as in their social engagement and family life.

Posted on: 09 September 2025 The Irish Longitudinal Study on Ageing (TILDA) has released its 'Wave 6' findings which points to challenging times for Ireland's older population. Ireland is one of the fastest ageing countries in Europe, with the population aged 65 and over projected to double by 2051.
