The Territorial and Socio-Environmental Transformation cluster brings together researchers who seek to understand and support—even stimulate—the transformations that human societies must undertake in the face of major contemporary challenges.

The transformation of our societies is affecting the construction of our lives and life courses. These are traversed by a dual movement of de-standardization and de-institutionalization, leading to a gradual detachment from social roles, but also to a rise in social, cultural and gender uncertainties and inequalities. The "Transitions and Ages of Life" cluster studies the way in which these life courses are recomposed according to new social constraints and normative imperatives. It thus focuses on the fragility of populations at any age of life, and also on the repercussions of political devices and measures on the construction of life courses.This cluster brings together researchers from different disciplinary backgrounds who analyze both the normative transformations affecting life courses and life-age transitions..

The Chair is dedicated to the study of security, from both traditional and critical approaches. Its axis of rotation is the analysis of safety performance - at cultural, organizational and technological levels - and its relationship to social order. Here, safety is approached primarily from a transdisciplinary angle. This localization of safety, at the intersection of several disciplinary influences, directly structures the theoretical and methodological orientations of the studies conducted within the Chair.

A practical training course in computational quantum chemistry was organized from May 26 to 30, 2025 as part of an ERASMUS+ collaboration between the University of Sfax and the University of Namur. This inter-university training course for PhD students in chemistry and physics from the Tunisian University brought together more than 20 students.

Abstract Radiotherapy is a cornerstone of cancer treatment and is currently administered to approximately half of all cancer patients. However, the cytotoxic effects of ionizing radiation on normal tissues represent a major limitation, as they restrict the dose that can be safely delivered to patients and, consequently, reduce the likelihood of effective tumor control. In this context, delivering radiation at ultra-high dose rates (UHDR, > 40 Gy/s) is gaining increasing attention due to its potential to spare healthy tissues surrounding the tumor and to prevent radiation-induced side effects, as compared to conventional dose rates (CONV, on the order of Gy/min).The mechanism underlying this protective effect-termed the FLASH effect-remains elusive, driving intensive research to elucidate the biological processes triggered by this type of irradiation.In vitro models offer a valuable tool to support this research, allowing for the efficient screening of various beam parameters and biological responses in a time- and cost-effective manner. In this study, multicellular tumor spheroids and normal cells were exposed to proton irradiation at UHDR to evaluate its efficacy in controlling tumor growth and its cytotoxic impact on healthy tissues, respectively.We report that UHDR and CONV irradiation induced a comparable growth delay in 3D tumor spheroids, suggesting similar efficacy in tumor control. In normal cells, both dose rates induced similar levels of senescence; however, UHDR irradiation led to lower apoptosis induction at clinically relevant doses and early time points post-irradiation.Taken together, these findings further highlight the potential of UHDR irradiation to modulate the response of normal tissues while maintaining comparable tumor control.JuryProf. Thomas BALLIGAND (UNamur), PresidentProf. Stéphane LUCAS (UNamur), SecretaryProf. Carine MICHIELS (UNamur)Dr Sébastien PENNINCKX (Hôpital Universitaire de Bruxelles)Prof. Cristian FERNANDEZ (University of Bern)Dr Rudi LABARBE (IBA)

For more than 30 years, the Department of Flexible Scheduling at the Faculty of Economics, Management, Communication, and Political Science (EMCP) at the University of Namur has been helping adults returning to school to acquire new skills. In 2023, the Department launched a brand-new program: a Master's degree specializing in sustainable development management and economics. This one-year program addresses environmental and societal challenges by training professionals to support the ecological and economic transition. 

In May 2025, the Department of Physics welcomed two special visitors: Serge Mathot and François Briard from Namur, both alumni of UNamur and members of CERN. Several activities were on the program, ranging from a visit to the particle accelerator, to science popularization and thematic seminars, particularly in heritage sciences. The aim? To identify areas or activities in which UNamur and CERN could strengthen their collaboration.

The discovery of nuclear energy marked a turning point in human history. Today, alongside debates about its role in energy production and its destructive potential, nuclear energy continues to be used in a wide range of fields, such as medical research and cancer treatments. At UNamur, nuclear energy is thus at the heart of the work of biologists, physicists, and art historians.
