In some organisms, germ blastomeres appear to enter a state of transcriptional quiescence. For example, in the worm Caenorhabditis elegans, transcription is activated in somatic blastomeres as early as the 4-cell stage, whereas it is not initiated in germline blastomeres until the 100-cell stage. This transcriptional repression in germ blastomeres has been attributed to the PIE-1 protein, specifically localized in these cells from the first embryonic division. PIE-1 is thought to inhibit the activity of CDK-9, a cyclin-dependent kinase previously considered essential for the phosphorylation of serine 2 (CTD-Ser2) of the C-terminal domain (CTD) of RNA polymerase II and for transcription elongation. However, recent studies, showing that embryogenesis proceeds normally in a mutant strain expressing a CTD in which serines 2 is replaced by an alanine (CTD-S2A) and identifying CDK-12 as the main kinase phosphorylating CTD-Ser2, call this model into question.To study the transcriptome of germline blastomeres in the worm C. elegans, an approach combining cell sorting and RNA sequencing (RNA-seq) was developed. Pilot analyses validated this method on a wild-type strain, enabling its use on a strain in which PIE-1 can be specifically degraded using the Auxin-Inducible Degron (AID) system. This made it possible to examine the effect of PIE-1 depletion on the transcriptome of germline blastomeres revealing that in its absence, germline blastomeres adopt a transcriptional profile close to that of somatic blastomeres, confirming the fundamental role of PIE-1 in preserving germline identity during embryogenesis. In parallel, the fission yeast Schizosaccharomyces pombe was used to analyze the consequences of PIE-1 expression in a heterologous organism. The results showed that PIE-1 by localizing near transcription termination sites induces further transcription by RNA polymerase II beyond the termination site, leading to transcription of intergenic regions. These observations led to the hypothesis that in C. elegans,within germinal blastomeres, PIE-1 might regulate alternative polyadenylation in 3' untranslated regions, producing longer RNA isoforms susceptible to degradation. In the absence of PIE-1, shorter isoforms could be generated, allowing accumulation of somatic transcripts and potentially degradation of maternal mRNAs via somatic protein translation. Although further investigations are required in C. elegans to validate this hypothesis, it provides an innovative conceptual framework for understanding the role of PIE-1, independent of CTD-Ser2 phosphorylation.

Several researchers at the Namur Institute of Structured Matter (NISM) have recently been awarded funding from the F.R.S - FNRS following calls whose results were published in December 2024. The NISM Institute federates the research activities of the chemistry and physics departments of the University of Namur.

Researchers at ULiège and UNamur are developing a new electrochromic material: MoWOx.

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.

Depuis son inauguration en 2019, l’observatoire astronomique de l’UNamur a déployé un programme pédagogique et de médiation scientifique ouvert à toutes et à tous, avec l’ambition de faire découvrir les sciences par le prisme de l’observation des merveilles du ciel. 5 ans plus tard, le pari est réussi ! La petite équipe qui anime les lieux multiplie les collaborations et les activités proposées aux étudiantes et aux étudiants, aux écoles et au grand public. Cet automne, l’Observatoire astronomique célébrera l’empreinte durable qu’il a construite dans les yeux et les cœurs de son public en fêtant son 5e anniversaire. Une occasion de rassembler la communauté qui s’est développée autour de ses projets passés, présents et futurs !

Dear teachers, We are pleased to invite you to a unique educational experience at the Antoine Thomas Astronomical Observatory. Offer your students the opportunity to discover the Antoine Thomas Astronomical Observatory, an observatory built on the very site where the Jesuit fathers established their own observation, training and research dome in the 19th century. Located in downtown Namur, in the heart of the university, our observatory is equipped with state-of-the-art instruments, for both night-time and daytime observation, with one of Belgium's largest solar telescopes. A visit to the observatory allows you to discover how astronomy is practiced today and - weather conditions permitting - to observe the sun in complete safety. Plan your visit today! To organize a school visit, please complete the registration form available on our website. Practical information:Guided tour 1ère to 6ème secondaire 1:30 pm to 2:30 pm or 3:00 pm to 4:00 pm Faculty of Medicine - Place du Palais de Justice, Namur Gratuit - Sur inscription The observatory is not accessible to people with reduced mobility Next date:February 11, 2025This activity is organized with the support of Wallonie Recherche.

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.
