In a new study published in February 2023 in the Journal of Luminescence, an international group of scientists led by Sébastien Mouchet from UNamur, reported the previously unknown fluorescence properties of transparent insect wings. This research highlights the valuable information that can be obtained from advanced optical characterisation techniques.

The Namurians of the Year for 2022 are known! Organised by the ASBL "Namurois de l'année" in partnership with the magazine AlluMeuse, the "Namurois de l'année" ceremony has just unveiled the Namur personalities who have distinguished themselves over the past year. And among them, in the science category, we find Anthony Cleve, professor in the Faculty of Computer Science.

The Ten-years Most Influential Paper award has just been presented to three members of UNamur's Faculty of Computer Science: Xavier Devroey, Gilles Perrouin and Maxime Cordy. The award recognizes the paper published ten years previously that has had the greatest impact on the research community. It was awarded at the 18th edition of the International Working Conference on Variability Modelling of Software-Intensive Systems (VAMOS '24), which took place in early February in Bern, Switzerland..

Lately, and thanks to LUMI, one of Europe's largest supercomputers, the limits of our knowledge of cell lipid membranes have been pushed back. A team of Namur researchers, including Professor Benoît Champagne and Drs. Pierre Beaujean and Charlotte Bouquiaux, has just published in the Journal of Chemical Information and Modeling. The results of this study pave the way for new approaches in the field of membrane lipid therapy.

The University of Namur is involved in the European CERTAINTY project, an initiative led by the German Fraunhofer Institute to explore new avenues in cancer treatment. Launched in December 2023, this European consortium is funded by the European Union - Horizon Europe program - to the tune of almost 10 million euros over the next 4.5 years.

One year after receiving funding from the European Research Council (ERC) for his B-Yond project, Prof Guillaume Berionni has just been named a Fellow of the prestigious European chemistry society Chemistry Europe. This distinction makes him the new representative for Belgium for a period of 2 years.

The annual conference of Trail, the structure that brings together all artificial intelligence researchers in the Wallonia-Brussels Federation, and entitled "Inclusion, Parcimony and Plurality: the Future of AI?", was held at UNamur on May 14. 150 participants came to listen to a particularly rich and varied program.

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.

Initiated in 1969 by Pullmann and Del Re, the congress is an annual meeting to promote collaboration and friendship between Latin-speaking theoretical chemists. In its early years, European researchers were the main contributors. Subsequently, the Latin American community has made a major contribution, with the emergence of teams whose international reputation now extends far beyond our own community.We are delighted to be holding this meeting at the University of Namur, 55 years after the first CHITEL was organised in Paris, France. We are sure that this 2024 edition will once again be an opportunity to take advantage of the good humour and dynamism of Latin to encourage, develop and strengthen scientific exchanges.We look forward to welcoming you at the University of Namur,The CHITEL 2024 Local Organising Committee.

A bilingual French-sign language dictionary (LSFB), which can be queried in both languages, thanks to cutting-edge technology (facial recognition) and access to a vast database compiling more than 4,500 signs, words and expressions.

Let's go and discover the qualified researchers of UNamur, winners of the funding granted by the FNRS in 2022. Today, we meet Michaël Lobet, currently a lecturer at UNamur, who will begin his new mandate as a qualified FNRS researcher at the NISM Institute next fall. The subject of his research: twisted optics for the manipulation of slow photons or how to create light traps. Explanations.

How can teleworking and face-to-face work be reconciled? How can these professional practices be framed to reinforce the innovative and sustainable dimensions of hybrid work? These are the questions that Michel Ajzen, a specialist in organizational management, is tackling as part of his teaching assignments in the Department of Management Sciences at UNamur. His research focuses on hybrid work and organizational innovation, with a transdisciplinary approach aimed at reinventing managerial practices to meet contemporary challenges.
