Multi-robot systems are physically embodied networks — they sense, move, and communicate through the physical world. The bar for safe decision-making rises as these systems enter safety-critical, real-world settings where they must perform well under uncertainty. Our work shows that physicality is a resource against the two kinds of uncertainty they face: intentional (or adversarial), where data is manipulated by malicious agents, and natural, where aspects of the environment are simply unknown. Most of this talk concerns intentional uncertainty. Here, one way to exploit physicality is by using communication as a sensor. Because the signals robots exchange are difficult to forge, they carry evidence that can be cross-validated to yield a quantifiable likelihood that an agent's data is trustworthy. This is the foundation of cy-trust, in which stochastic observations of trust model an agent's trustworthiness probabilistically from physical rather than cryptographic evidence. Each neighbor's contribution is then weighted by its trust value. Under this framework, we show that consensus, distributed optimization, and other core coordination tasks admit almost-sure convergence with bounded deviation from their nominal performance, even when malicious agents exceed half of a node's connectivity, past the classical Byzantine bound. We support this finding with both theory and hardware experiments under adversarial attack. Against natural uncertainty, we show that real-time sensing can be folded into rollout-based reinforcement learning, where the same machinery reweights futures rather than neighbors. We apply this idea to routing a fleet of robots to stochastically appearing demand and, with Project CETI, to the first autonomous robotic rendezvous with sperm whales at sea. Finally, we preview some of our future work combining trust with long-horizon sequential decision-making, targeting planning that stays provably resilient when the data informing the plan may itself be corrupted.

Memories are not static representations but evolve over time through consolidation and their progressive reorganization across distributed brain networks. This process allows memories to remain persistent while also becoming sufficiently flexible to guide behavior in novel situations. In this seminar, Gisella Vetere will discuss how memory engrams are reorganized from learning to remote recall and how distinct neuronal ensembles contribute to the balance between memory specificity and generalization. Combining activity-dependent neuronal tagging, circuit manipulations, and brain-wide analyses, her research seeks to uncover how memories are transformed over time and how these transformations shape adaptive—and potentially maladaptive—behavior.

Lysosomes sit at the crossroads of cellular catabolism and quality control, where they must dismantle chemically diverse cargo while preserving their own integrity. I will discuss two discoveries that reveal how lysosomes solve these complementary challenges and how their failure creates disease vulnerabilities. First, I will describe Lysosomal Leucine Aminopeptidase (LyLAP), an enzyme specialized to processively degrade the hydrophobic α-helices of transmembrane proteins. LyLAP is highly expressed in pancreatic ductal adenocarcinoma, where its loss causes hydrophobic peptides to accumulate, compromises lysosomal function, and ultimately leads to cancer cell death, revealing a potential vulnerability in tumors with elevated endocytic activity. I will then describe LASER, a damage-responsive protein assembly that couples lysosomal membrane injury to repair. At its core, the oligomeric protein TFG recognizes LC3/GABARAP proteins conjugated to damaged lysosomes and recruits the ESCRT machinery to restore membrane integrity. Neurodegenerative disease-associated mutations in TFG disrupt this process, linking defective lysosomal repair to human disease. Together, these findings reveal lysosomes as dynamic systems that coordinate cargo degradation with membrane surveillance and repair to maintain cellular homeostasis.

Le stress et l’anxiété font aujourd’hui partie intégrante du quotidien, d’autant plus dans un cadre professionnel. Pression de performance, surcharge d’informations, incertitudes et distractions digitales, nous affectent toutes et tous. Lorsqu’ils deviennent chroniques, ces états impactent la santé mentale, le sommeil, la concentration, la motivation, les relations sociales et la qualité du travail.
\r\n
\r\nComprendre ces mécanismes, apprendre à les réguler, et surtout identifier ses propres déclencheurs et ressources devient alors essentiel pour évoluer dans un cadre professionnel et promouvoir un travail stable et une qualité de vie plus saine.
\r\n
\r\nCette formation vise à renforcer votre résilience, vous permettre d’identifier vos déclencheurs personnels, et d’activer des ressources internes et externes pour retrouver calme, clarté mentale et stabilité au quotidien.
Le projet Unearthed de l’artiste Rahel Oberhummer est une aventure visuelle et scientifique au cœur du développement de micro-organismes contenus dans le pergélisol de la montagne Muot da Barba Peider (Schafberg) en Engadine et collectés par l'Institut fédéral de recherches sur la forêt, la neige et le paysage (WSL). Cette collection préserve des micro-organismes provenant de régions menacées telles que les Alpes et l'Arctique et compte déjà plus de 2000 spécimens.
\r\n
\r\nL’artiste a sélectionné des levures, bactéries et champignons souvent vieux de 12’000 ans, qu’elle a cultivés dans son propre studio et photographiés tous les deux jours. Les différents micro-organismes sont déposés sur un fond d’agar pour qu’ils puissent se développer. Leur évolution est rapide et hasardeuse. La documentation est méthodique : plus de 13'300 photographies ont été prises représentant des instantanés de matière vivante.
\r\n
\r\nDeux séries de photographies ont été produites : l’une se concentre sur des monocultures, dans lesquelles une souche microbienne sélectionnée occupe une boîte de Pétri et se propage largement. En adaptant les méthodes d'inoculation et les milieux de culture, différentes impulsions sont déclenchées. La deuxième série fait cohabiter plusieurs organismes différents. La lutte pour les nutriments dans le milieu de culture ainsi que les symbioses qui peuvent se développer entre les microbes sont documentées. La pratique d’atelier se mêle à la pratique de laboratoire.
\r\n
\r\nL’exposition
\r\n
\r\nL’exposition Unearthed présente 18 photographies de plusieurs micro-organismes différents évoluant dans les boîtes circulaires qui les abritent. Filaments, textures, entrelacs, pointillés, cercles produisent des configurations abstraites spectaculaires. Les couleurs enchantent et vivifient les formes en turbulente circulation et en constante métamorphose. Les photographies pointent le sublime de l’extraordinaire variété des cellules : la naissance du vivant.
\r\nLes photographies de Rahel Oberhummer révèlent deux nécessités indissociables : d’une part celle de comprendre le vivant même dans ses organismes les plus simples et d’autre part de le préserver. Parallèlement, il s’agit de créer des images qui manifestent la qualité visuelle des formes et des couleurs de ces micro-organismes. Notre rapport à la nature exige l’admiration de sa beauté. Aujourd’hui, des artistes comme Rahel Oberhummer s’engagent dans une double mission : participer activement à des processus scientifiques et créer des images sensibles tout autant que savantes.

\r\n
\r\nRahel Oberhummer (*1991, Loèche-les-Bains) est diplômée de la HEAD, Genève. Elle a étudié aussi à la Royal Danish Academy of Fine Arts, Copenhague, à la Hochschule für Kunst und Design de Lucerne et au Billy Blue College of Design à Sydney. Au début de l’année 2026, elle a obtenu une résidence de trois mois à Hanoï, au Vietnam, dans le cadre d’un séjour de recherche soutenu par Pro Helvetia et accueilli par l’espace Exutoire. Elle vit et travaille à Vevey.
\r\nLa relation entre les structures sociales humaines et les formes de vie non humaines est au cœur de son approche artistique. Rahel Oberhummer se concentre sur les interactions subtiles entre les humains et l'environnement, avec une attention soutenue pour les écosystèmes dont nous dépendons et que nous mettons pourtant en danger. Des questions se posent, que l'artiste explore à travers une recherche scientifique autant qu’artistique.
