On 9 June 2023, the NISM and naXys Institutes, the Physics and Chemistry Departments and the Namur Research College were delighted to welcome Prof. Jean-Luc Brédas from the University of Arizona. A prestigious speaker of international renown, Prof. Brédas completed his doctoral thesis with Prof. Jean-Marie André at the University of Namur.

Very often in nature, we observe phenomena of natural synchronisation and the emergence of regular patterns: a crowd applauding in unison at the end of a concert, the cells in the walls of the heart pulsating in a coordinated fashion, black and white stripes on a zebra, brown spots surrounded by black in leopards... But how can we explain this uniformity if there is no global controller or explicit rule directing this coordination?

BepiColombo will fly past Mercury on 19 June 2023. It will pass close to the planet's surface at an altitude of approximately 236 km. BepiColombo is an ESA/JAXA mission involving a team of researchers from the University of Namur (naXys institute).

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.

Modelling the Universe to understand how it came into being, how it works and how the physical objects that make it up work - that's the day-to-day work of the researchers in the naXys SPACE cluster. It's a subject that fascinates not only scientists. An international conference on "Complex Planetary Systems (CPSII)" is being organised at UNamur from 3 to 7 July 2023, with activities open to the public, including two round tables, a show at the Delta and a Space Quiz!

At a time when around a fifth of Europe's 200,000 species are threatened with extinction, researchers from the University of Namur are taking part in a pan-European consortium to act fast and together to generate high-quality genome resources on a large scale.

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.

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.

A pterosaur from Brazil that preserved melanosomes in its feathers provides insight into the function of primitive feathers. An international team of palaeontologists and geologists, including UNamur (Dr Aude Cincotta and Prof. Johan Yans), has demonstrated that pterosaurs, the flying cousins of dinosaurs, had feathers and were able to control their colour.

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.

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.

Within the SPACE pole of the naXys Institute, researchers are interested in the evolution of planetary systems at different scales: space debris, natural and artificial satellites, asteroids, (exo)planets, etc. As part of the JUICE mission, post-doctoral researcher Alexis Coyette and Professor Anne-Sophie Libert are interested in Ganymede, one of Jupiter's moons, and are seeking to model its internal composition and rotation. It is believed that this satellite has a global ocean of liquid water beneath its surface. The study of its rotation will provide more information about this ocean and thus the potential habitability of this satellite.
