What is a perfect fluid? It is a theoretical model of a fluid that allows us to assume that the fluid is not viscous, that it does not conduct heat, that it is incompressible and does not create vortices. It is therefore an approximation of reality that simplifies theoretical predictions of fluid flows. For the first time, an international team has experimentally demonstrated this same behaviour for light immersed in a medium of low refractive index.

An international team of researchers, including Prof Frederik De Laender, from the University of Namur, publish in Nature Communications. The editor highlights that the authors use theoretical models and field data to show how eco-evolutionary processes can force species to develop more similar characteristic traits in more species-rich communities to avoid competition. Which goes against what we intuitively perceive.

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.

Increasingly sophisticated technologies are invading our spheres of activity without our prior consultation as citizens. Shouldn't the new digital tools, artificial intelligence or technologies resulting from progress in neuroscience, which are transforming our identity and social relationships, be the subject of broad and sufficiently informed democratic debates? This question is at the heart of the international "research-action" project "A new humanism in the age of neuroscience and artificial intelligence" in which UNamur is participating.

This is a technical and scientific feat that has just been patented at the UNamur. Researchers from the Laboratory of Analysis by Nuclear Reactions (LARN), the Department of Physics of UNamur (NISM Institute) and the spin-off Innovative Coating Solutions (ICS) have succeeded in developing a carbon-based coating with innovative properties that can be used in a wide range of fields, including fuel cells, decoration, and mechanical parts for automobiles.

As part of the English course of the Bachelor in Science and Medicine, students are introduced to the oral popularisation of scientific concepts. This year, these future biologists, chemists, geologists/geographers or pharmacists expressed themselves in the form of videos inspired by the famous French science popularisation programme, "C'est pas sorcier". A competition to choose the best video has been launched as part of the Printemps des sciences.

A frightening figure in traditional tales, the wolf is the object of a myth carried by the popular memory of our elders. Long gone from our landscapes, this large predator is making a comeback in Wallonia and is posing us with major challenges. Does it still have a place? A historian and a veterinarian talk about this fascinating natural phenomenon.

The wolf, a majestic animal that has had many tumultuous adventures with man. Respected in ancient Rome, then demonised from the Middle Ages onwards, the wolf is now gaining ground in Belgium after having disappeared from our lands since the end of the 19th century. This subject was at the heart of the conference "Return of the wolf in the Walloon Region", organised by UNamur on 9 March 2023. This was an opportunity to decipher the past and present presence of the wolf in our countryside and forests, with Julie Duchêne, FRESH-FNRS doctoral student in History, and Benoit Muylkens, Head of the Department of veterinary medicine.

From 17 April 2023, UNamur will host two prestigious international Francqui Chairs. Professor Timoteo Carletti (Department of Mathematics - naXys Institute) will host Professor Ginestra Bianconi, one of the leading experts on networks and high-order structures. Professor Romain Houssa (Faculty of Economics, Social Sciences and Management - DeFiPP Institute) will welcome Professor Karel Mertens, an expert in macroeconomics.

Raising students' awareness about the importance of contraception was the aim of the Sexual Health Week organised on campus by the Biology Circle. It took place from 13 to 17 March 2023.

At the beginning of each academic year, the Board of Trustees grants Namur Research College (NARC) Fellowship status to researchers who demonstrate a high level of research achievement and who have recently received a prestigious award or funding. A look back at the fellowship of Professor Frederik De Laender.

The Department of Art History and Archaeology of UNamur is participating for the first time in an experimental archaeology project, within the framework of a doctoral thesis on the production of glass in the Roman period. Conducted in partnership with Malagne, the Rochefort archaeopark, the Specularia project aims to gain a better understanding of the reality of the gestures and techniques of Gallo-Roman craftsmen and to scientifically validate hypotheses that are still debated today. To carry out this experiment, the Department of Art History and Archaeology is launching its first participatory funding.
