Pollution and health of marine ecosystems | A publication that challenges current knowledge
Dr. Sébastien Mouchet, a researcher at UNamur and member of the NISM and ILEE Institutes, has just published the results of research focusing on the effects of pollution on coral reef fish in MDPI-Optics. The findings of the international, multidisciplinary team lead to crucial conclusions with implications for the health of marine ecosystems.

The "Même pas peur! between education, experience and commitment
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.

ILEE lunch seminar
Quentin Willot (Biology) has just joined URBE for a two-year post-doctoral position (Marie Sklodowska-Curie Action, supervisor: Alice Dennis) on a project called ChillAnts. This project focuses on the study of adaptation to extreme temperatures in holarctic (trans-Beringian) ant species, from a physiological, ecological and evolutionary point of view. Quentin will present a more technical aspect of his work (Thermal Death Time Curve Modelling).

ILEE Research day
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!

Biodiversity and the value of nature: geographer Nicolas Dendoncker co-authors a major international publication
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.

A gift for labs in the Faculty of Science and Faculty of Medicine
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.

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.

The long-term effects of pollution in our rivers, oceans and lakes
From 11 to 13 May 2022, a hundred or so scientists and actors from the economic and cultural world gathered at UNamur to discuss the issue of water pollution. The aim? To share and enrich knowledge, but also to alert and inform about its long-term effects on fauna, flora and human beings. Scientific sessions, workshops and a conference for the public were on the programme for these three days.

ILEE lunch seminar
His long-term collaboration with Dr. Aniruddha Chatterjee recently resulted in the first collaborative framework agreement between the University of Otago and UNamur, as well as an international Erasmus+ (EU) credit mobility funding this scientific mission. Frédéric Silvestre deepened his understanding of the advanced DNA methylation techniques employed by Dr. Chatterjee's team, including their bioinformatics workflows and innovative approach to epigenetic editing. He has given several seminars presenting LEAP's research on mangrove rivulus and turquoise molefish. He also presented at the Australasian Epigenetic Alliance conference and had the opportunity to explore potential new collaborations with other departments, including zoology, sustainable development, chemistry and marine sciences.

At the heart of Madagascar's ethical and environmental challenges
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.
