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 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 master's student in physics at the University of Namur, Kevin Persoons is not only passionate about science, he also embodies student and cultural engagement! At 24, he already has several years of involvement in university life under his belt, notably within the General Student Assembly (AGE), where he has served as administrator, cultural delegate, and then president. Today, as a youth representative, he is preparing to promote Namur on the European stage.

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.

For several years now, researchers have been striving to make their laboratories "greener". A series of actions have been implemented, funded by the CaNDLE 2023 call for projects have been supported by the Department of Biology at the initiative of Alison Forrester and Frédéric Silvestre, the project leaders, as well as by Campus Infrastructure Management Services (SIGeC) and Prevention Services (SerP). In March 2025, a Green Day was held to provide information on the project's progress, and to motivate people to join the initiative.  

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.

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.

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)

Five years after its inauguration, the Astronomical Observatory of the University of Namur has been enriched by a new set of instruments unique in Belgium: a Schmidt astrograph of the Rowe-Ackermann type, 28 cm in diameter, equipped with a 62-megapixel full-format color camera. These exceptional instruments will offer the public an immersive educational experience unrivalled in the Walloon Region.
