Created on the initiative of the Belgian Nuclear Research Center SCK CEN, this Chair is awarded every two years by the F.R.S.-FNRS and the FWO to recognize a leading researcher in the field of nuclear sciences and their applications. In 2025, the Chair will pay tribute to Carine Michiels' brilliant career and her outstanding contributions to radiobiology and cancer research. 

South America is a subcontinent rich in natural and cultural resources. Between biodiversity preservation and development cooperation, UNamur maintains valuable partnerships to address the challenges of biodiversity loss and understand current socio-economic transformations. Immersion in Ecuador and Peru. 

At a time when bacterial resistance to antibiotics is a public health problem, Professor Stéphane Vincent's team is currently developing dynamic constitutional frameworks (Dynamic Constitutional Frameworks, DCF): a molecular system that would be able to break down certain resistances and thus deliver antibiotics as close as possible to pathogens.

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. Explanations.

The F.R.S.-FNRS has just published the results of its various 2025 calls for proposals. These include the "Credits & Projects" and "WelCHANGE" calls, as well as the "FRIA" (Fund for Research Training in Industry and Agriculture) and "FRESH" (Fund for Research in the Humanities) calls, which aim to support doctoral theses. What are the results for UNamur? Twenty-eight projects have been selected, demonstrating the quality and richness of research at UNamur. 

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).

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.

The IBAF Meetings have been organized since 2003, every two years since 2008, by the Ion Beams Division of the French Vacuum Society (SFV), the oldest national vacuum society in the world, which celebrated its 80th anniversary in 2025.As in previous editions, IBAF 2026 will offer a rich and varied program with guest lectures, oral and poster presentations, and technical sessions. All this will be complemented by an industrial presence to promote exchanges between research and innovation. The conference will cover a wide range of topics, from ion beam instruments and techniques to the physics of ion-matter interactions, including the analysis and modification of materials, applications in the life sciences, earth and environmental sciences, and heritage sciences.

Abstract Primarily described as an alarmone, secondary messenger (p)ppGpp, when accumulated, binds to many targets involved in DNA replication, translation, and transcription. In the asymmetrically-dividing a-proteobacterium Caulobacter crescentus, (p)ppGpp has been shown to strongly impact cell cycle progression and differentiation, promoting the non-replicating G1/swarmer phase. Mutations in the major subunits of transcriptional complex, b or b' subunits, were able to display the (p)ppGpp-related phenotypes even in the absence of the alarmone. We identified that the transcriptional holo-enzyme, RNA polymerase (RNAP) is a primary target of (p)ppGpp in C. crescentus. Furthermore, mutations that inactivate (p)ppGpp binding to RNAP annihilated the (p)ppGpp-related phenotypes and phenocopied a (p)ppGpp0 strain. Our RNAseq analysis further elucidated the changes in the transcriptional landscape of C. crescentus cells displaying different (p)ppGpp levels and expressing RNAP mutants. Since the DNA replication initiation protein DnaA is required to exit the G1 phase, we observed that it was significantly less abundant in cells accumulating (p)ppGpp. We further explored its proteolysis under the influence of (p)ppGpp. Our work suggests that (p)ppGpp regulates cell cycle and differentiation in C. crescentus by reprogramming transcription and triggering proteolytic degradation of key cell cycle regulators by yet unknown mechanisms. In Part II, we identified two σ factors belonging to the ECF family that might be involved in this (p)ppGpp-accompanied phenotypes. In Part III, we propose an overlapping role of the ω subunit, RpoZ, and the heat shock subunit, RpoH, in carbon metabolism.JuryProf. Gipsi LIMA MENDEZ (UNamur), PresidentProf Régis HALLEZ (UNamur), SecretaryDr Emanuele BIONDI (CNRS-Université Paris-Saclay)Prof. Justine COLLIER (University of Lausanne)Dr Marie DELABY (Université de Montréal)
