The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) has just published a study in the prestigious journal Nature, listing and assessing the different values we place on nature. Nicolas Dendoncker, professor in the Department of Geography and member of the ILEE Institute at UNamur, is one of the co-authors.

At the 12th International Congress on Mesostructured Materials (IMMA), held from July 8 to 12 in Montpellier, Prof. Bao-Lian Su was re-elected President of the International Mesostructured Materials Association (IMMA).

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.

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.

EMBO Courses and Workshops are selected for their excellent scientific quality and timelines, provision of good networking activities for all participants and speaker gender diversity (at least 40% of speakers must be from the underrepresented gender). Organisers are encouraged to implement measures to make the meeting environmentally more sustainable.Upon registration - More info and registration on the EMBO website.

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.

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.

ECOBAT is an EOS project (FNRS/FWO) that brings together four universities: UCLouvain, KULeuven, the University of Bonn (Germany), and the University of Namur. This consortium currently mobilizes some twenty researchers at all levels (Masters, PhD students, post-docs, promoters), including Dr. Pierre Beaujean, under the supervision of Professor Benoît Champagne..

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.

In a new publication, the European Reference Genome Atlas (ERGA) announces the success of its pilot project. This pioneering initiative has brought together a vast collaborative network of researchers and institutions in 33 countries to produce high-quality reference genomes of 98 European species. This continental effort paves the way for a new, inclusive and equitable model of biodiversity genomics.

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...
