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.

A delegation from the Université de Namur took part in an exploratory mission to the Université Cheikh Anta Diop (UCAD) in Dakar, Senegal. The aim: to discover the research carried out in the field, meet UCAD researchers and initiate future collaborations between the two institutions.

The Covid-19 pandemic is a human tragedy that has caused millions of deaths worldwide and put our entire society under great strain. But it has also been a tremendous collective moment for many UNamur scientists, whose research continues in an attempt to better understand this disease and its consequences.

The three Belgian scientific experiments selected to be carried out on board the International Space Station (ISS) during astronaut Raphaël Liégeois' mission in 2026 have just been unveiled by the Federal Science Policy Public Service (Belspo). One of them is carried by a team from UNamur for an experiment at the crossroads of biology and physics aimed at analyzing the resistance of the "blob", an atypical unicellular organism.

Beautiful victory for Margaux Mignolet, a researcher at the Faculty of Medicine's Unité de Recherche en Physiologie Moléculaire (URPhyM), who wins 1st prize in the Belgian inter-university final of the Ma thèse en 180 secondes (MT180) competition. Her research? To better understand the mechanisms of antibodies active in cases of long COVID. The second prize in this national competition was also won by a candidate from Namur. It was Petra Manja, from the Unité de Recherche en biologie des micro-organismes (URBM), Department of Biology, Faculty of Science, and is pursuing a thesis aimed at understanding resistance mechanisms in the bacterium E. coli. Both are also researchers at the NARILIS Institute.

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)

This is a first in Wallonia! The Citadelle de Dinant now offers an augmented reality tour that plunges visitors right into the heart of its history. At the helm: the French company Histovery, specializing in heritage reconstructions, with scientific support from Axel Tixhon, professor in the History Department at UNamur.
