Max Collinet, professor of geology at the Faculty of Science and researcher at the Institute of Life, Earth and Environment (ILEE), has just been awarded equipment funding (EQP) from the F.R.S - FNRS following calls whose results were published in December 2024.

They are future veterinarians, doctors, lawyers, historians, geographers, or even computer scientists, and they share this common point: the concern to train themselves, voluntarily, in the challenges of sustainable development and transition. Since October 2024, 25 mainly 3rd-year students from various UNamur faculties have been taking part in a pilot experiment: the Journées de l'Education au Développement Durable et à la Transition (JEDDT). This Monday, March 17, they presented in a creative form, the fruit of their reflection after 6 months of training.

Several researchers at the Namur Institute of Structured Matter (NISM) have recently been awarded funding from the F.R.S - FNRS following calls whose results were published in December 2024. The NISM Institute federates the research activities of the chemistry and physics departments of the University of Namur.

Researchers at ULiège and UNamur are developing a new electrochromic material: MoWOx.

An international research team led by the Swedish University of Agricultural Sciences has uncovered how pharmaceutical pollution alters the behaviour and migration patterns of Atlantic salmon in nature. Professor Eli Thoré, from the Department of Biology and the ILEE research institute at the University of Namur, contributed to this groundbreaking field study, which has just been published in Science.

The 24th edition of Printemps des Sciences was held from March 24 to 30 throughout Wallonia and Brussels, on the theme of "Eau-rêka". The aim of this annual event is to make science and technology accessible to as many people as possible. Mission accomplished for this new edition!

The 11th edition of the Ma Thèse en 180 secondes competition was held this Friday, March 28, 2025 at the Faculty of Science. Three biologists will represent UNamur at the Belgian final, to be held in Mons on May 21.

How can we better understand the landscape around us? For over ten years, UNamur has been offering continuing education in landscape analysis. What does this concept involve? What are its objectives? And how is landscape analysis practiced? Answers with Corentin Fontaine, Coordinator and Trainer for "Les Ateliers du Paysage" organized by UNamur's center for continuing education in science and mathematics (CeFoSciM).

Maxime Lucas is an FNRS Research Fellow in the Department of Mathematics and a member of the naXys Institute. He works on complex systems within the "Network Dynamics" cluster headed by Professor Timoteo Carletti. He is co-author of two papers on complex systems, recently published in prestigious journals Nature Physics and Physical Reviews Letters.

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.

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.
