The European Euclid satellite will be launched into space from Cape Canaveral in the United States at 5.11pm on Saturday 1 July. The telescope is intended to provide a more accurate map of billions of galaxies over a distance of around twelve billion light years. A team of Belgian scientists and engineers from UCLouvain, ULB, ULg, UNamur and Ghent University, as well as the Space center in Liège (CSL), took part in this ten-year project, bringing together more than 3,500 people from 21 countries.

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.

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.

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.

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...

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 three Belgian scientific experiments selected to be carried out on board the International Space Station (ISS) during astronaut Raphaël Liégeois' mission in 2026 have just been unveiled by the Federal Science Policy Public Service (Belspo). One of them is carried by a team from UNamur for an experiment at the crossroads of biology and physics aimed at analyzing the resistance of the "blob", an atypical unicellular organism.

An astrophysics expert, Professor André Fűzfa (Faculté des sciences, Institut Naxys) also harnesses his scientific knowledge to take everyone on a journey into the world of the imagination, through literature. Finding Ganymede is his new novel, co-created with illustrator Fabrice Rasir, an alumnus of the Mathematics Department. A book that incorporates images generated by artificial intelligence (AI). The novel is thus a skilful blend of graphic AI, physics and fiction that helps stimulate the imagination while providing an instructive dimension.

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.
