His long-term collaboration with Dr. Aniruddha Chatterjee recently resulted in the first collaborative framework agreement between the University of Otago and UNamur, as well as an international Erasmus+ (EU) credit mobility funding this scientific mission. Frédéric Silvestre deepened his understanding of the advanced DNA methylation techniques employed by Dr. Chatterjee's team, including their bioinformatics workflows and innovative approach to epigenetic editing. He has given several seminars presenting LEAP's research on mangrove rivulus and turquoise molefish. He also presented at the Australasian Epigenetic Alliance conference and had the opportunity to explore potential new collaborations with other departments, including zoology, sustainable development, chemistry and marine sciences.

Quentin Willot (Biology) has just joined URBE for a two-year post-doctoral position (Marie Sklodowska-Curie Action, supervisor: Alice Dennis) on a project called ChillAnts. This project focuses on the study of adaptation to extreme temperatures in holarctic (trans-Beringian) ant species, from a physiological, ecological and evolutionary point of view. Quentin will present a more technical aspect of his work (Thermal Death Time Curve Modelling).

Space has become a major economic and strategic issue. As a member of the European UNIVERSEH Alliance, UNamur explores this space theme in its various departments, from physics to geology, via mathematics, computer science or philosophy. Without forgetting to address the general public, who still dream of the stars...

High-Sensitivity Birefringence Mapping Using Near-Circularly Polarized Light I will describe several techniques for mapping a two-dimensional birefringence distribution, which can be classified according to the optical schemes and principles of work:Illumination geometry (transmitted light/reflected light)Image acquisition (sequential acquisition/simultaneous acquisition)Polarization control (electrically controlled variable retardance/mechanical rotation).This classification facilitates a comparative analysis of the capabilities and limitations in these methods for birefringence characterization. Polychromatic polarizing microscopy (PPM) provides unique capabilities to alternative methods. It leverages vector interference to generate vivid, full-spectrum colors at extremely low retardances, down to < 10 nm. PPM is a significant departure from conventional polarizing microscopes that rely on Newton interference, which requires retardances above 400 nm for color formation. Furthermore, PPM's color output directly reflects the orientation of the birefringent material, a feature absent in conventional microscopy where color is solely determined by retardance.Joint seminar of ILEE & NISM!The seminar is open to external people too, no need to register.

From 2020 to 2025, as part of her doctoral thesis in history, researcher Julie Duchêne conducted a ground-breaking investigation blending history and biology to trace the cohabitation between humans and wolves in Wallonia and Luxembourg, from the 18th to the early 20th century. Thanks to an innovative interdisciplinary approach, including DNA analysis of naturalized 19th-century specimens, her work sheds light on the mechanisms that led to the local extinction of the species. This research was made possible thanks to the support of numerous scientific and cultural partners.

Professor Eli Thoré and Justine Bélik have just been honoured by the Adrien Bauchau Fund (FAB). Created in memory of the founder of the Biology Department at UNamur, the FAB has been promoting excellence in education and research in the life sciences since 1989.

An unusual piece of research recently mobilized teams from UNamur's Biology Department. Genetic analyses carried out by the Environmental and Evolutionary Biology Research Unit (URBE) were able to confirm the protected status of a herd of wild mouflons based in Gesves, and thus highlight the importance of saving them.

In 2025, two iconic Walloon products—Walloon honey and Liège white blood sausage—were awarded the prestigious European PGI designation. Behind this success lies the AgriLabel project, to which UNamur has been contributing for over a decade. Working alongside producers, specialists, and public institutions, our Department of History played a decisive role: demonstrating, through historical sources and scientific analysis, the close connection between these products and their local terroir. A project at the heart of economic, identity-related, cultural, and scientific issues.

Well hidden from passersby, caves nevertheless conceal particularly aesthetic secrets. For the past four years, Martin Vlieghe has been pursuing a PhD in geology at UNamur.  He is exploring the origin of the surprisingly varied colours of certain concretions nestled in the heart of Belgian and French caves. Together with Prof. Johan Yans and Gaëtan Rochez, he samples, observes, and analyses these magnificent objects with the aim of uncovering the mysteries they conceal.

In the coming months, the University of Namur will participate in an exceptional space mission aboard the International Space Station (ISS), alongside Belgian astronaut Raphaël Liégeois. The BeBlob project, led by researchers Boris Hespeels (ILEE Institute) and Anne-Catherine Heuskin (NARILIS Institute), aims to study the DNA repair capabilities of a fascinating organism: the blob (Physarum polycephalum).

Today, our planet is undergoing major climatic changes. Particularly in the face of rising temperatures, it is not easy to predict how flora and fauna will react and adapt in disturbed ecosystems. International research, in which Professor Johan Yans' team (Department of Geology and ILEE Institute) is taking part, has found some answers in fossils, which have been the memory of Darwinian evolution for millions of years.

This doctoral study assesses pathways to enhance coastal sustainability in the Anthropocene, by promoting the sustainable use of mangroves and strengthening their social-ecological resilience through an interdisciplinary approach. The thesis is structured into four specific objectives: assessing the role of traditional beliefs and local deities in promoting the sustainable use of mangroves, analyzing the synergies between legal frameworks and traditional beliefs in enhancing the social-ecological resilience of mangroves, developing a novel interdisciplinary framework to evaluate the social-ecological resilience of mangroves, and operationalizing the proposed framework in Benin's mangroves, West Africa.  We collected field data using ethnobiological surveys, drone image analysis and document review, in-depth interviews, focus group discussions, plant and fish inventories across three coastal communities in Benin. The study draws insights from the seven principles of resilience to analyze mangrove sustainability. The interdisciplinary methodology of this study links plant biology, fisheries sciences, and human geography to analyze mangroves as complex social-ecological systems. Findings of the thesis show that traditional beliefs and local deities play a significant role in regulating the use of mangrove resources, while the overlapping of formal and informal institutions offer opportunities to enhance their social-ecological resilience. The novel proposed framework called Mangrove Social Ecological Resilience Appraisal (MaSERA) outlines variables and indicators tailored to mangroves to assess their social-ecological resilience. Its application in Benin highlights its potential in identifying factors that enable or erode mangrove resilience, for informed decision making. The study argues that promoting the sustainable use of mangroves and enhancing their social-ecological resilience represent dual imperatives for achieving coastal sustainability in the Anthropocene. It contributes to the growing body of knowledge on mangrove conservation and provides actionable insights for integrated coastal zone management.
