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.

Abstract Since its emergence in 1996, the Asian H5 Goose/Guangdong (Gs/Gd) lineage has circulated widely in poultry in southern China, spilling over to wild birds by 2002. Wild bird infections facilitated global dissemination via migratory waterfowl and repeated spillback into poultry, challenging the view that HPAI primarily arises from LPAI mutation. Subclade 2.3.4.4b emerged in Asia in 2013, reached Europe in 2016, caused recurrent epizootics, diversified into multiple genotypes, became dominant in wild birds, and shows zoonotic potential.This thesis investigates critical knowledge gaps regarding H5Nx subclade 2.3.4.4b in poultry: (1) early within-flock spread after punctual introduction in chickens, particularly during the first European epizootics; (2) influence of pre-existing immunity on silent circulation; (3) limitations in diagnostic throughput during epizootic peaks; (4) potential of environmental surveillance, including air and dust sampling; and (5) impact on egg contamination and the reproductive tract, relevant for food safety and zoonotic risk.Four main objectives were addressed: (1) development of an experimental model simulating punctual introductions and spread, comparing 2017 and 2020 strains and assessing pre-existing immunity; (2) enhancement of diagnostic capacity via alternative sampling, semi-automated RNA extraction, and high-throughput processing; (3) evaluation of air and dust sampling for virus monitoring under experimental and field conditions; and (4) assessment of egg contamination risk. Alternative sampling and environmental monitoring were also applied to Newcastle disease virus as a comparative notifiable pathogen.

This doctoral study assesses pathways to enhance coastal sustainability in the Anthropocene, by promoting the sustainable use of mangroves and strengthening their social-ecological resilience through an interdisciplinary approach. The thesis is structured into four specific objectives: assessing the role of traditional beliefs and local deities in promoting the sustainable use of mangroves, analyzing the synergies between legal frameworks and traditional beliefs in enhancing the social-ecological resilience of mangroves, developing a novel interdisciplinary framework to evaluate the social-ecological resilience of mangroves, and operationalizing the proposed framework in Benin's mangroves, West Africa.  We collected field data using ethnobiological surveys, drone image analysis and document review, in-depth interviews, focus group discussions, plant and fish inventories across three coastal communities in Benin. The study draws insights from the seven principles of resilience to analyze mangrove sustainability. The interdisciplinary methodology of this study links plant biology, fisheries sciences, and human geography to analyze mangroves as complex social-ecological systems. Findings of the thesis show that traditional beliefs and local deities play a significant role in regulating the use of mangrove resources, while the overlapping of formal and informal institutions offer opportunities to enhance their social-ecological resilience. The novel proposed framework called Mangrove Social Ecological Resilience Appraisal (MaSERA) outlines variables and indicators tailored to mangroves to assess their social-ecological resilience. Its application in Benin highlights its potential in identifying factors that enable or erode mangrove resilience, for informed decision making. The study argues that promoting the sustainable use of mangroves and enhancing their social-ecological resilience represent dual imperatives for achieving coastal sustainability in the Anthropocene. It contributes to the growing body of knowledge on mangrove conservation and provides actionable insights for integrated coastal zone management.

For its inaugural conference, the SPiN (Science & Philosophy in Namur) center will be joined by Claire Rommelaere, a lawyer and researcher at the Center for Bioethics at the University of Namur, and Aude Bandini, a philosopher of science at the University of Montreal, to take a critical look at the theme of "distrust of science." The urgency of addressing this issue is clear in our era, where, despite an overall stable level of trust in science, the parameters of public debate are frequently blurred by misinformation.Having had the opportunity to observe philosophers of science in their natural habitat for nearly fifteen years, Claire Rommelaere will share her thoughts on whether or not we should trust those who think about science.For her part, Aude Bandini will address a major problem that we all face at a time when the mass of available knowledge is such that it is impossible to acquire it on our own. Indeed, the socially distributed nature of knowledge generally leaves us no choice but to rely on the authority of experts, even on very important issues (such as health). However, when we rely on others in this way and follow recommendations that, due to our ignorance, we have no means of evaluating, we place ourselves in a relationship of "epistemic dependence" that conflicts with our aspirations for intellectual autonomy and forces us to ask ourselves a question whose answer may prove unbearable: is intellectual autonomy nothing more than a myth?Conference hosted by journalist Maïté Warland.Program:5:30-6:30 p.m. | Drinks at Quai 22 (Rue du Séminaire 22, 5000 Namur)6:30 p.m. | Claire RommelaereDistrust of philosophers of science7:00 p.m. | Aude Bandini Intellectualautonomy in the face of scientific authority: a headache for social epistemologyRegistration deadline: April 16.Free of charge.

A plant does not seem to have much in common with animals. Yet naturalists of the eighteenth and nineteenth centuries attempted to study plants as if they were animals: they set out, for example, to find an equivalent to the circulatory or respiratory systems. Why did they feel the need to resort to analogical reasoning? What results did they obtain? And more generally, what is the value of this type of reasoning?On the agendaTuesday, May 5, 202612:15 PM – Welcome and light lunch1:30 PM – Introductory remarksThibault De Meyer (University of Namur): Why Analogy?2:15 PM – Session 1: Theory and Practice - Cristiana Oghina-Pavie (University of Angers): The analogy of pragmatic knowledge: actions and transactions in 19th-century horticulture and Quentin Hiernaux (FNRS / Free University of Brussels): The plant-animal analogy employed by A.-P. de Candolle’s physiology in addressing the issue of the sensitivity of living beings3:45 PM – Coffee break4:15 PM – Plenary Session 1 - Thierry Hoquet (University of Paris Nanterre): Is the plant/animal analogy valid?5:45 PM – End of the first day7:00 PM – Conference dinnerWednesday, May 6, 20269:00 AM – Welcome9:15 AM – Session 2: Relationships and Boundaries of the Living - Dario Galvão (University of Namur): Analogy and the Faculties of the Living: Animal Reason and Plant Sensibility in the Enlightenment and Ugo Batini (University of Poitiers): Understanding Humanity Through Plants: Analogy and the Metaphysics of the Living in Schopenhauer10:45 AM – Coffee break11:15 AM – Plenary Lecture 2 – Pascal Duris (University of Bordeaux): Plants as Humans.

Abstract Wood combustion has historically provided essential heat and remains a crucial renewable energy source today. However, residential batch combustion inherently emits significant pollutants, including CO, VOCs, and PM. Since primary optimization measures cannot completely eliminate these emissions, secondary post-combustion remediation is necessary.To address this, the University of Namur and Stûv collaborated to evaluate the integration of a monolithic oxidation catalyst into an 8 kW residential wood stove.The initial study demonstrated exceptional abatement, reducing CO by 87%, PM by 66%, and highly toxic PAHs by over 90%. Crucially, in vitro assays on human lung cells proved that this chemical reduction directly translates to a 50% decrease in overall emission cytotoxicity.Subsequent mechanistic investigations using advanced speciation (PTR-TOF-MS) mapped the partial oxidation of non-methane VOCs. This revealed that the catalyst’s overall conversion efficiency is primarily limited by mass transfer rather than chemical kinetics.Finally, to overcome the inherent variability of batch combustion, a precise simultaneous direct-comparison methodology was developed. This novel approach confirmed the overall study’s findings, providing a robust and accurate framework for evaluating residential abatement technologies.

Ethics is practiced in hospitals. But ethics is also practiced in care and support facilities for the elderly and people with disabilities, as well as in pharmaceutical companies, research centers, and universities.We “practice ethics” in groups whose scope may be local, regional, national, continental, or international. We “practice ethics” by organizing conferences, conventions, meetings, roundtables, workshops, symposia, think tanks, and so on.But what exactly “do we do” in these settings? Is there really anything in common among all these groups, these settings, these collectives? It is not desirable to strive for a single model that would ignore the specific characteristics of the environments in which this activity takes place.But it is interesting and undoubtedly necessary to seek to better understand and define what each group does in this regard.
