Knowledge Wednesday: colors - where do they come from?
Colors - where do they come from?
Did you know that the color of your favorite red candies was made from little caterpillars? Accompanied by an archaeologist, your children plunge into history as they discover the different materials behind the colors used in paint. They'll be able to try out centuries-old recipes and paint their own illuminations.Fun workshops for kids Workshops with a variety of active pedagogy themes during which your children will develop their sense of observation, analysis and critical thinking through experiments, scientific games and extraordinary discoveries. In practiceWho are the workshops for? The workshops are aimed at children aged between 9 and 12. The number of children per workshop is limited to ensure optimal learning (12 children). The workshop runs if a minimum of 5 children are registered. How do the workshops work? The workshops are held one Wednesday afternoon a month from 2pm to 4pm at the University of Namur. Participation in a workshop costs €5 per child. This price includes supervision, materials and a snack. It is possible to register your children for several or all workshops and thus benefit from an advantageous rate. Reservations close 15 days before the activity date. Please note: preferential rate for children of UNamur staff (discount code: PromoUNamur).Your children are looked after and accompanied by a team of activity leaders. Who organizes the workshops? The workshops are organized by Confluent des Savoirs, UNamur's research outreach and dissemination unit. The team, experts in the transmission of knowledge, works in collaboration with university researchers to offer workshops in which your children question, reflect and experiment while having fun!

Fête de la Musique at Quai22
The Fête de la Musique à Namur , is just over twenty free concerts from June 20 to 23, all styles of music combined, inviting the public to wander, open-minded and curious, from a cultural venue to a garden, a courtyard, a café terrace or a store, in search of a variety of musical universes, sometimes festive, sometimes more hushed, even singular. It's a grassroots project that aims to recapture the original spirit of the Fête de la Musique: a warm atmosphere, great encounters and spontaneous sharing between musicians and audiences.On June 22, come and discover the Namur-based project Orphée.Freely inspired by the eponymous myth, this Namur-based project reappropriates the story to create an original musical form: halfway between techno, classical, ambient and field recording. It draws its inspiration from both primitive and contemporary electronic music. Electrodes that capture variations in the electrical potential of plants generate experimental, improvised music. Electricity ignites the electronic circuits of the modules, energy exalts the plants and love electrifies Orpheus. The result is unique music, powerfully organic and adventurous.Mix & Live analog visuals by Analog Memory aka François Gustin - Myth of Orpheus adapted by Julie Csik & Benoît VermerThe event is free!More information here.

Stellar Scape
With its deep skies that hypnotize and subjugate, space exerts an unrivalled fascination on the human species. As the Anthropocene crisis shakes our balances (environmental, technological, democratic), the 'Land of Night' is by turns the last frontier to be colonized, a resource to be exploited, a tourist destination, an observatory for remote surveillance, a dumping ground for orbiting debris, and forever the infinite constellation of our original interrogations as well as our (meta)physical reveries.From the atomic fragment to the great universal whole, the Stellar Scape exhibition brings together some two dozen international artists, researchers and engineers around the imaginaries of astronomy and the revival of space adventures. Through art installations, immersive environments, scientific innovations, speculative projects, we experience this expanding starry landscape, mirroring the cosmic link that connects us in a single space to all those things that appear there not only as they are, but also as they could be.

Gray-Scott Summer School on High-Performance Computing
The school will deal with optimizing computations on different types of hardware (CPU, GPU), presenting their respective characteristics, architectures and bottlenecks. It will cover both generic optimization methods applicable to all types of hardware, and the various libraries, technologies and languages available to achieve the best possible performance. Ideally, the machine's peak performance. Hardware considered: CPU, GPU.Languages considered: C++17, C++20, CUDA, Fortran, Rust, PythonLibraries considered: SYCL, Eve, Numpy, cunumerics, legate, Jax, Thrust.Compilers considered: G++, Clang++, nvc++, gfortran, nvfortran, dpc++.Profiling tools: Valgrind, Maqao, Perf, NSight, Malt and NumaProfAll methods will be illustrated on simple examples, such as Hadamard products, reductions, barycenter calculations and matrix products in order to be applied to a single problem: the simulation of a Gray Scott reaction. This problem is simple enough to be understood quickly, yet complex enough to be difficult for compilers to optimize without help. Each method will be broken down into simple versions, using default options, and one or more advanced versions, which will allow their advantages and disadvantages to be discussed and quantified.For more information on its content, please consult the school websiteOn the University of Namur satellite site, you'll enjoy the following benefits: Interaction with official LAPP trainers; Group support and a good working atmosphere; Lunch and a drink at the end of the day on the first day; You choose what you want to follow on site. We encourage you to come on the first day, but you make up your own program on the other days.To register for the UNamur satellite site: https://docs.google.com/forms/d/e/1FAIpQLScxikCQTfsQl9zZfnidm4xLSuDpdJGcgyLKOfJ2wo4VMgrgRw/viewform

Public defense of thesis - Louise GÉRARD
ABCB5 belongs to the ABC transporter superfamily composed of 48 members. These transporters have been extensively studied for their role in cancer multidrug resistance and, more recently, in tumorigenesis. ABCB5 has been identified as a marker of skin progenitor cells, melanoma stem cells, and limbal stem cells. Its expression has also been reported, among others, in melanoma, colorectal cancer, hepatocellular carcinoma and several hematological malignancies. The unique feature of ABCB5 is that it exists as both a full transporter (ABCB5FL) and a half-transporter (ABCB5β). Several studies have shown that the ABCB5β homodimer, in contrast to ABCB5FL, cannot confer multidrug resistance. Since these studies focused on a limited number of drugs, we cannot exclude the possibility that this homodimer may be involved in drug resistance or biological functions that have yet to be elucidated. However, it is also reasonable to hypothesize that ABCB5β could dimerize with other half transporters of the ABCB family to become functional. Using three complementary techniques: (1) nanoluciferase-based bioluminescence resonance energy transfer, (2) coimmunoprecipitation, and (3) proximity ligation assay, we identified two novel heterodimers in two melanoma cell lines: ABCB5β/B6 and ABCB5β/B9. Both heterodimers could be expressed in High-Five insect cells when both interacting partners were fused using the linker region of ABCB1, resulting in chimeric heterodimers. ATPase assays revealed that all chimeric heterodimers have a basal ATPase activity and that both functional nucleotide-binding domains in each dimer are required for their basal ATPase activity. Also, we obtained preliminary data suggesting that ABCB5β traffics from the endoplasmic reticulum to melanosomes independently of its dimerization, suggesting that its heterodimers might be located in similar organelles. However, several limitations were encountered when attempting to confirm their intracellular localization. Finally, since several anti-ABCB5 antibodies in the literature have shown a lack of specificity, we generated a mouse monoclonal anti-ABCB5 antibody in collaboration with Atlas Antibodies. The specificity of this antibody was demonstrated by immunofluorescence, making this antibody an important tool in the characterization of ABCB5β and ABCB5FL. Although further studies are needed to elucidate the physiological relevance of ABCB5β heterodimers, preliminary data support the hypothesis that ABCB5β is involved in melanogenesis. Taken together, these results represent an important step towards elucidating the functional role of ABCB5β in melanocytes and melanoma.

CHITEL 2024 - Congress of Theoretical Chemists of Latin Expression
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.
