Recognized for his expertise in ecotoxicology, Professor Patrick Kestemont is one of the scientific experts mandated by the Walloon Region, to advise the Government and examine all the consequences on human health of PFAS, these chemical substances present in our environment.

At a time when around a fifth of Europe's 200,000 species are threatened with extinction, researchers from the University of Namur are taking part in a pan-European consortium to act fast and together to generate high-quality genome resources on a large scale.

Characterization of trehalase from Acyrthosiphon pisum for the design of new insecticides SummaryAphids are major pests in agriculture, causing direct damage to plants and acting as vectors for phytopathogenic viruses. Conventional insecticides are widely used to control them, but their toxicity and efficacy pose problems in terms of the environment, human health and the emergence of resistance to these compounds. New alternatives are therefore needed, such as biological control using predators or parasitoids. However, these methods are not always economically viable on a large scale. As part of this thesis, another approach is being explored which involves developing new insecticides targeting the biochemical functions of aphids.The project aims to discover new inhibitors of trehalase, an enzyme essential for insect energy metabolism. Inhibition of this enzyme could disrupt vital insect functions without affecting mammals. This research involved several stages: the purification and complete characterization of trehalase from Acyrthosiphon pisum (the model for this study), the in vivo, in vitro and in silico analysis of commercial inhibitors on this enzyme, before moving on to the search for new inhibitors. Two points of integrated insect management were explored, biological and chemical control.The biological side saw the study of a strain of Streptomyces naturally producing trehalase-inhibiting metabolites, notably validamycin A, a molecule recognized in the literature as one of the best inhibitors, but not applicable as an insecticide. Other molecules appear to have interesting features, but we have not been able to isolate and characterize them.The chemical side has enabled us to create a pharmacophore hypothesis based on experimental results on molecules obtained by virtual screening. Although these molecules are not usable as insecticides as they stand, this hypothesis provides a better understanding of trehalase inhibitors in general and can be used to refine future analyses.

In 2021, the European Union has embarked on a titanic project to safeguard the genomes of all eukaryotic species in Europe. In other words, all living organisms, with the exception of bacteria and archaea (micro-organisms). Called ERGA, for European Reference Genome Atlas, and in which UNamur is participating thanks to Professor Alice Dennis, this project hopes to help safeguard biodiversity, at a time when a fifth of European species are in danger of extinction..

The wolf, long banished from our lands, has made a remarkable comeback in Wallonia since 2016. This mysterious being, now protected, arouses as much fascination as fear. Through an exhibition, held as part of the Cultural Project course, third-year history bachelor students have traced the history of the wolf. From April 11 to 27, 2024, the exhibition entitled "Même pas peur! Une évolution de l'image du loup à travers les siècles" invited audiences to plunge into the heart of a historical exploration.

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!

Researchers from UNamur's Departments of Biology and Physics have conducted a scientific experiment to assess the radioresistance of the common black ant Lasius niger. The results of their work have just been published in the Belgian scientific journal Belgian Journal of Zoology. The Namur-based scientists demonstrate a level of resistance far superior to that of humans. Their spontaneous approach also demonstrates a lesser-known approach to scientific research.

With oral and poster presentations by ILEE affiliates. Students and young researchers are particularly invited to present their research and practice their presentation skills in English. The day is also important for ILEE members as it enables them to keep abreast of ongoing projects in different disciplines and to foster collaboration.At the end of the day, the annual general meeting of all members will take place with a summary of the past year's activities and achievements.We are honored to announce that Arnaud Péters, PhD in history and founder of sites_H, will be the keynote speaker!

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.

Located in the Indian Ocean, Madagascar is an island with a rich natural heritage and multiple cultural influences. For over 15 years, researchers from the University of Namur have been working with a number of Madagascan universities and institutes on a variety of themes, including environmental preservation, water management and institutional capacity building. Focus on some of these projects.

In late November, the Mont-Saint-Guibert-based company Cellistic® donated equipment it no longer used to UNamur. By enabling the university to give this equipment a second life, Cellistic is making an important gesture in support of the development of university research.
