Stanford University has published a prestigious ranking that highlights the most influential researchers in a wide range of scientific fields. The list, based on bibliographic criteria, aims to provide a standardized means of identifying the world's scientific leaders. It is one criterion among others for assessing the quality of scientific research. Twelve researchers from the University of Namur are among them!

While still only a dream, the quantum computer is the subject of intense research. The Artemis project, funded by the European Union (EU) and involving UNamur, aims to develop new sources of single photons, and thus lay the technological foundations. A member of the project, physicist Yves Caudano hopes, at the same time, to further explore the foundations of quantum physics.

In October 2024, Guillaume Berionni, a researcher in the Department of Chemistry at the University of Namur, received the Royal Society of Chemistry's (RSC) triennial prize from its President, Professor Anne-Sophie Duwez. A fine reward for his research team in organometallic reactivity and catalysis (RCO), but also for our institution and its Department of Chemistry.

If interdisciplinarity is a buzzword within the academic bureaucracy, it's hard to conclude that it exists in practice. Embracing a slogan does not an epistemology make, and claiming progress is no guarantee of it. To prevent the interdisciplinary approach from being reduced to avant-gardism, it is necessary to define the practical conditions for bringing together the different social sciences, going beyond the encounter between academic disciplines or the eclectic taste for the exotic. The eight sessions of the course presented below will seek to provide both a method for the construction of analytical notions by young researchers in history and sociology, and a set of tools favoring the objectification of scientific work in the social sciences.Session 2 - The construction of notions: analytical operators, comparatism and singular conceptsAs the division of labor between sociology as a producer of notions and history as a source of examples constitutes one of the main epistemological obstacles to a consistent practice of historical sociology, it is necessary to define a method for the elaboration of notions that can serve as analytical operators. In this context, the question of comparatism, a term covering diverse and sometimes contrary practices, appears central.Possibility of following the seminar online via Teams

The F.R.S.-FNRS has just published the results of its various 2024 calls. Equipment calls, research credits and projects, FRIA doctoral grants and Mandant d'Impulsion Scientifique (MIS), there are many instruments to support fundamental research. Find out more about UNamur's results.

Space has become a major economic and strategic issue. As a member of the European UNIVERSEH Alliance, UNamur explores this space theme in its various departments, from physics to geology, via mathematics, computer science or philosophy. Without forgetting to address the general public, who still dream of the stars...

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)
