Harnessing botanical remedies for respiratory health
Plant-based cough syrup - a blend of tradition and science
Muhammad Siddiq, a PhD student, recently carried out a project exploring natural alternatives to synthetic cough syrups, with a focus on medicinal plants from the TCD Botanical Garden. This independent project, while separate from his doctoral research on plant chemistry and climate change, contributes to the broader conversation about the role of plants in healthcare.
Siddiq’s work focused on identifying plants with potential cough-relieving properties, drawing on both historical knowledge and scientific evidence. He highlighted five plants known for their medicinal value: Allium sativum (garlic), prized for its antibacterial and immune-boosting effects; Aloe vera, recognized for its soothing and anti-inflammatory properties; Equisetum hyemale (horsetail), a mild expectorant; Thuja occidentalis, traditionally used for respiratory congestion but requiring controlled use due to its thujone content; and Rubus armeniacus (blackberry), rich in antioxidants that help alleviate throat irritation.
Using these plants, Siddiq developed a natural cough syrup, blending garlic extract, aloe vera juice, horsetail infusion, blackberry syrup, and honey—an age-old natural remedy known for its preservative and throat-soothing properties. This simple yet effective formulation offers a plant-based alternative to commercial cough syrups and demonstrates the potential of botanicals in modern medicine.
Although separate from his PhD research, Siddiq’s work highlights the relevance of plant-based treatments in healthcare, bridging traditional knowledge with modern scientific validation. His project also emphasizes the value of locally available medicinal plants, many of which visitors to the TCD Botanical Garden can explore firsthand to learn about their historical and medicinal significance, both in Ireland and beyond.

Behind-the-Scenes of the Evolutionary Weathering Experiment at the VAL Lab
Preparing for the Evolutionary Weathering Experiment – A Behind-the-Scenes Look
As part of the TERRAFORM ERC-funded project, the upcoming evolutionary weathering experiment in the Variable Atmosphere and Light (VAL) Laboratory aims to investigate how vegetation influences silicate weathering and its role in shaping geochemical cycles over time. This project requires extensive preparation to establish precise experimental conditions for plant-mineral interactions in a controlled setting.
A selection of plant species has been carefully acclimated to growth chambers, where they will be monitored under controlled environmental conditions. These plants will be grown in a specialized mineral substrate, allowing researchers to examine weathering processes over time. The study will involve regular geochemical assessments to track changes in environmental variables.
Extensive groundwork has been undertaken to ensure experimental consistency, from refining growth conditions to optimizing substrate composition. The climate chambers have undergone thorough testing to maintain stable conditions, ensuring a replicable study environment.
With preparations nearly complete, this research aims to provide valuable insights into how plant evolution has influenced biogeochemical cycles and atmospheric processes. Stay tuned for future updates and findings!

Final Year Thesis Spotlight on Investigating Plant Responses and Molecular Signaling
How do plants sense their environment?
Philip Brennan is a final-year Botany undergraduate student. He is working under the supervision of Dr. Ailbhe Brazel who is a Teaching Fellow on the Terraform project. Philip will be answering questions on how plants dynamically respond to their environment by integrating multiple molecular mechanisms. Philip will be working with a commonly used model organism in plant genetic research, Arabidopsis thaliana. Arabidopsis is a small herbaceous plant in the Brassicaceae family, a family containing many of the crops we eat every day such as cabbage, broccoli, cauliflower and turnip. Philip will be taking advantage of the vast genetic resources available in Arabidopsis to dissect the interactions between different molecular signalling pathways in response to stress and development. He will be using molecular as well as microscopy techniques in his project.

Connecting Through Stories - The Power of Storytelling at European Researchers' Night
Science Storytelling at European Researcher's Night
On September 27, 2024, the Botany Department hosted an interactive performance titled Storytelling Your Science as part of the European Researchers’ Night. The event, organized by intern student Yoshii Jawei Xu and delivered by members of the Plant Climate Lab, including Catarina Barbosa, Antonietta Knetge, Katie O’Dea, and Dr Sate Ahmad, invited participants to experience science through a unique, human-centred approach.
This innovative project transformed researchers into “audio books,” sharing brief, personal narratives about their scientific journeys, including both achievements and challenges. By emphasizing the emotional and subjective aspects of their work, the event sought to challenge the common perception of scientists as detached or unemotional. Instead, it highlighted the deep commitment and emotional resilience required to pursue a career in research.
The goal of this event was to communicate science in a non-traditional format, fostering deeper audience engagement and reshaping how researchers are perceived. The project proved highly successful, attracting approximately 200 attendees, including both casual passersby and those who came specifically for the Human Library experience.
Although the original plan was for 10-minute stories, the sessions often extended beyond 30–40 minutes, illustrating the profound impact of personal storytelling in building connections. Each participant, or “book,” effectively conveyed their experiences, creating meaningful dialogue and engagement.
While there is always room for improvement, the event provided valuable insights and demonstrated the power of personal narratives in science communication. It has also inspired greater confidence in pursuing future initiatives.
Special thanks are extended to Val Lab and Professor Jennifer McElwain for their support in making this opportunity possible.
Trees as Climate Warriors - Dublin's Long-Term Study on Trees, Air Quality, and Carbon Sequestration
Third Year of the monitoring project "Witness Tree" in Trinity College Botanic Gardens & National Botanical Gardens
Researchers at Plant Climate Lab entered the third year of the 30-year-long “Witness Trees” project to study how trees can help fight climate change and improve air quality. Using the mix of native and non-native trees, the project collects long-term data on carbon capture, air filtration, and ecosystem health in Dublin. This year, trees from both Trinity College Botanic Gardens and the National Botanical Gardens were included, expanding the study to North Dublin.
Led by Prof. Jennifer McElwain, with contributions from Dr Sate Ahmad, Dr Christos Chondrogiannis, Dr Michelle Murray, and Erasmus Master students Tina Monteiro and Morgane Weissenburger, the research aims to identify tree species most effective at absorbing pollutants and requesting carbon. The findings will provide valuable insights for future urban planning, helping cities adapt to environmental stresses. By focusing on species’ resilience and performance under varying conditions, the project not only supports Ireland’s climate goals but also offers insights into how urban forests can aid in addressing climate change worldwide.

Our Erasmus Adventure - Botany, Friendship, and New Skills at Trinity College
Our Erasmus Adventure - Botany, Friendship, and New Skills at Trinity College
Hi guys, we’re Tina and Morgane, two French students who completed our six-month master’s internship at the Trinity College Botanical Department. This internship was our first international experience and allows us to improve our English skills while learning a lot about botany.
We’ve been warmly welcomed by the entire team, which is quite diverse in botanical science and ecology, and allowed to learn about different fields of botany. The team was always there to help when needed and we had the chance to attend social events outside work. The botanical garden is a very peaceful place that we thoroughly enjoyed. We loved working in this environment and having the opportunity to take breaks by walking through the garden or sitting quietly in the arboretum to enjoy a ray of sunshine. It was also fascinating to observe the changes in the garden over the seasons, from winter to summer.
This internship allowed us to develop our autonomy and initiative, especially by adjusting our projects based on the skills we wanted to acquire. Working primarily independently taught us the importance of organization when handling long-term projects.
The experience of living in another country has enabled us to discover another culture, meet new people and discover amazing landscapes. It developed our self-confidence, independence, resourcefulness but also our English skills. The experience also enabled us to step out of our comfort zone and do things we’d never done in France.
Being an Erasmus student in this team was a great experience that helped us shape our professional path and explore a field that really interested us. Doing this experience together helped us to support each other while sharing very good souvenirs.
If you are a person who wants to meet people from around the world, improve your plant biology skills, and enhance your English, this is the right place for you!
Christos attends 2nd European Congress on Photosynthesis Research
2nd European Congress on Photosynthesis Research
After the success of the first edition, the European Congress for Photosynthesis Research came back in 2024. From June the 25th to the 28th 2024, experts in the field of natural and artificial photosynthesis gathered in the historic city of Padova (Italy), the cradle of the scientific method developed by Galileo, for an exciting second edition of this scientific event.
The conference started on the 24th of June with the ePS Young Session, tailored for PhD candidates and early-career postdocs. This session fostered an informal and interactive setting, encouraging discussions and idea exchanges among young participants from diverse institutes.
The main conference started with the opening talks in the impressive Aula Magna, the most impressive room of Palazzo Bo, where the great Galileo gave his lectures. The conference continued with numerous sessions on structure, acclimation and evolution of the photosynthetic apparatus, photosynthesis in microbes like algae and cyanobacteria, and new perspectives and technologies of photosynthesis like artificial photosynthesis. The attendees had the opportunity to enjoy a serene evening filled with delectable Italian cuisine and fine wine at the conference’s gala dinner. The conference was a huge success, and the participation exceeded the organizers’ expectations.
Dr. Christos Chondrogiannis presented his research on the presence of CAM activity in the ancient group of cycads. He proposed two species as potential candidates for facultative CAM activity. This project carried out in collaboration with Trinity College Botanic Gardens and National Botanic Gardens in Dublin, generated a lot of interest and led to in-depth discussions about the significance of the findings and the prospects of the project. The conference also provided an opportunity to establish future collaborations and rekindle friendships from previous conferences.

Fossil-hunting expedition across France
Fossil-hunting expedition across France
Over the past week (June 21st-28th), the two postgraduate members of the TERRAFORM team, Catarina Barbosa and Antonietta Knetge, travelled to Poitiers, France for fieldwork. Alongside Dr Bernard Gomez and his postgraduate student, Axel Montigny from the University Claude Bernard Lyon 1, they visited multiple Mesozoic exposures to collect leaf macrofossils and plant debris. The first quarry visited was in Persac, an Albian-Cenomanian (~ 100.5 ma) paleokarst locality with angiosperm leaves and various fauna such as bivalves, bony fish, crocodyliforms, dinosaurs, pterosaurs, and mammals. The group then travelled to the Île d’Oléron to excavate an early Tithonian locality (~149.2 ma), abundant in fossilised conifer wood. The subsequent localities visited offered excellent examples of different types of plant fossil preservation ranging from petrified, and silicified, to plant cuticles preserved in clay. Many of these sites were situated in the La Rochelle/Rochefort area, including the unique Île Madame, only accessible at low tide. The images below show the group on their last night of fieldwork as well as Eucalyptus-like angiosperm leaves from Puy-Puy (Albian-Cenomanian, ~ 100.5 ma) and the fossilised wood from Île d’Oléron.

XV. International Palynological Congress (IPC) XI. International Organisation of Palaeobotany Conference (IOPC)
Terraform researchers take part in IPC/IOPC Conference in Prague, Czechia
The emerging field of trait-based paleoecology suffers from the siloing of its practitioners along multiple dimensions including the availability of infrastructure and materials, and structure-specific focus. To promote the development of a more cohesive and collaborative ‘paleo-trait’ network Will Matthaeus and Jenny McElwain led a workshop on behalf of the ERC-TERRAFORM project at IPC/IOPC 2024. Following the recent publication by McElwain et al. (2024, New Phytologist, Tansley Reviews), 28 scientists from around the world and across career stages participated in a collaborative evaluation of the potential for utilizing plant functional traits in the fossil record. Attendees gave positive feedback and new collaborations were established in the discussions that followed.
Members of the TERRAFORM project participated in IPC/IOPC field trips. One trip was made to the Pecínov, a quarry in the late Cretaceous Bohemian Basin, circa 50 km west of Prague. The locality offers a transgressional set of sedimentary bodies that allow clear identification of the paleo-coastal area, moving inland through a salt marsh, swamp, and finally into a freshwater braided river. The Cenomanian flora from Pecínov has been extensively described, with an assemblage consisting of gymnosperm and angiosperm taxa. A PhD student from our team was able to collect plant macrofossil material from this locality for future research and was eager to recount her pleasant experience, meeting senior paleobotanists in the field and listening to their epic (and very-niche) plant-fossil tales of yore.
TERRAFORM’s two PhD students, Antonietta Knetge and Catarina Barbosa, presented their first major conference talk at IPC/IOPC in a session focused on the biotic crises of the Mesozoic. Stepping up the plate immediately after lunch, Catarina refused to let conference attendees take a nap by showing them a cool graph and talking about it a bunch. Her talk on paleoecology and turnover in the T/J boundary of East Greenland featured carefully developed visualizations of community composition through time at South Tancrediakløft. Antonietta then took to the stage to deliver a rousing presentation on diversity and taphonomy, using rarefaction curves to compare that same locality and Astartekløft, historically one of the most important sites for the Greenland T/J. Both talks garnered interest, lots of questions, and collaboration requests. A great success!
