At a time when bacterial resistance to antibiotics is a public health problem, Professor Stéphane Vincent's team is currently developing dynamic constitutional frameworks (Dynamic Constitutional Frameworks, DCF): a molecular system that would be able to break down certain resistances and thus deliver antibiotics as close as possible to pathogens.

Are we prisoners of our genetic heritage? Can filiation be reduced to genes alone? Can we escape our destiny? Existential questions we all ask ourselves, and to which Gaëlle Pontarotti, lecturer and researcher in the Department of Sciences, Philosophies and Societies at UNamur, sheds new light in her book Par-delà les gènes. Une autre histoire de l'hérédité, published last October by Gallimard.

The F.R.S.-FNRS has just published the results of its various 2025 calls for proposals. These include the "Credits & Projects" and "WelCHANGE" calls, as well as the "FRIA" (Fund for Research Training in Industry and Agriculture) and "FRESH" (Fund for Research in the Humanities) calls, which aim to support doctoral theses. What are the results for UNamur? Twenty-eight projects have been selected, demonstrating the quality and richness of research at UNamur. 

In the coming months, the University of Namur will participate in an exceptional space mission aboard the International Space Station (ISS), alongside Belgian astronaut Raphaël Liégeois. The BeBlob project, led by researchers Boris Hespeels (ILEE Institute) and Anne-Catherine Heuskin (NARILIS Institute), aims to study the DNA repair capabilities of a fascinating organism: the blob (Physarum polycephalum).

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.

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.

Abstract Primarily described as an alarmone, secondary messenger (p)ppGpp, when accumulated, binds to many targets involved in DNA replication, translation, and transcription. In the asymmetrically-dividing a-proteobacterium Caulobacter crescentus, (p)ppGpp has been shown to strongly impact cell cycle progression and differentiation, promoting the non-replicating G1/swarmer phase. Mutations in the major subunits of transcriptional complex, b or b' subunits, were able to display the (p)ppGpp-related phenotypes even in the absence of the alarmone. We identified that the transcriptional holo-enzyme, RNA polymerase (RNAP) is a primary target of (p)ppGpp in C. crescentus. Furthermore, mutations that inactivate (p)ppGpp binding to RNAP annihilated the (p)ppGpp-related phenotypes and phenocopied a (p)ppGpp0 strain. Our RNAseq analysis further elucidated the changes in the transcriptional landscape of C. crescentus cells displaying different (p)ppGpp levels and expressing RNAP mutants. Since the DNA replication initiation protein DnaA is required to exit the G1 phase, we observed that it was significantly less abundant in cells accumulating (p)ppGpp. We further explored its proteolysis under the influence of (p)ppGpp. Our work suggests that (p)ppGpp regulates cell cycle and differentiation in C. crescentus by reprogramming transcription and triggering proteolytic degradation of key cell cycle regulators by yet unknown mechanisms. In Part II, we identified two σ factors belonging to the ECF family that might be involved in this (p)ppGpp-accompanied phenotypes. In Part III, we propose an overlapping role of the ω subunit, RpoZ, and the heat shock subunit, RpoH, in carbon metabolism.JuryProf. Gipsi LIMA MENDEZ (UNamur), PresidentProf Régis HALLEZ (UNamur), SecretaryDr Emanuele BIONDI (CNRS-Université Paris-Saclay)Prof. Justine COLLIER (University of Lausanne)Dr Marie DELABY (Université de Montréal)
