New research from a team at Trinity College Dublin has unearthed a cheap and environmentally friendly new option for removing pollutants from our water. The key? Oyster shells that would ordinarily end up in landfill sites after consumption. The research, just published in the journal Science of the Total Environment , shows that waste seashells - especially those from oysters - can capture and remove rare earth elements from polluted water.

.This published research shows that Trinity scientists have discovered a way to "train" the immune system to better fight drug-resistant infections like MRSA and TB. Today is World TB Day 2026. As antibiotic resistance continues to rise worldwide, scientists are searching for new strategies to combat infections.

Researchers in Trinity College Dublin have found that a machine learning model could help clinicians predict which people with depression are more likely to improve with digital cognitive behavioural therapy compared to antidepressant medication. The study, led by researchers in the School of Psychology, also describes how digital cognitive behavioural therapy (CBT) can be personalised sooner than in other settings, such as face-to-face therapy.

The work, led by teams at Trinity and the FutureNeuro Research Ireland Centre, has pinpointed the mechanism linking some sports injuries to poor brain health in retired athletes. The research, published today in leading international journal Science Translational Medicine, has identified a breakdown in the blood-brain barrier (BBB) as the key link between repetitive head injuries (RHIs) and long-term brain health issues in this cohort.

From dragonflies to starfish, new Trinity research shows that the speed of visual perception across the animal kingdom is driven by lifestyle and environment, with fast-paced lives demanding faster vision. Animals don't just see the world differently from one another, they experience time itself at dramatically different speeds.

A new study led by researchers from Trinity and the Moffitt Cancer Center shows how radiation therapy can be used to expose-and then eliminate-therapy-resistant cancer cells using natural killer cell immunotherapy. Many patients with metastatic cancers receive therapy that is initially highly effective, often resulting in complete remission.

New Trinity study is first of its kind in Ireland to specifically focus on women to address the disproportionately poor physical health of this population when compared to the general population. A study published by Trinity College researchers from the School of Medicine in the journal BMJ Open , explored the effect of an exercise programme in a Dublin day centre for women who are dealing with challenging issues.

Researchers believe this study further highlights that a key immune system switch warrants full investigation in MS and may be a promising potential target for future MS therapies. Trinity College Dublin researchers have published a new study on MS that has uncovered evidence that a key immune system switch, known as the NLRP3 inflammasome, may play a significant role in the inflammatory processes associated with the pathogenesis of MS.

Trinity research shows that depending on how schemes are designed and delivered, wellbeing impacts can be positive or negative. Time spent in nature and peer discussion groups are key to fostering positive wellbeing outcomes. While AESs are a familiar part of modern farming they typically focus on environmental outcomes such as biodiversity and climate action.

Ireland's approach to protecting vulnerable energy consumers could help other countries phase out harmful electricity disconnections without destabilising power markets, new research has found.

Posted on: 03 February 2026 The research, led by neuroscientists from Trinity, combined brain imaging with artificial intelligence models.

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?
