Un aperçu de la recherche en Normandie

  • French classrooms are cautiously wiring up for AI, and the headline is nuance: little data collected, even less machine learning in use, and teachers firmly at the helm. A nationwide survey shows that “better protect to better value” remains the watchword as education players test-drive analytics while defending privacy and pedagogy. Study lead Solène Zablot with CIRNEF UR; IRIHS (with Khansa Ghabara and Éric Bruillard) maps the current terrain and urges human-in-the-loop designs that fit school values (Index 865).
  • On the wider Web, explainability has left the lab and entered the ethics page. At the Ethical Web Science workshop, Gaël Dias and colleagues at GREYC argue that if algorithms can’t explain themselves to citizens, they shouldn’t be steering anything of consequence. Their call to arms: pair technical clarity with social accountability so platforms stop being black boxes and start being public infrastructure (Index 552).
  • Meanwhile in the arts, words are learning to look. By infusing text encoders with visual cues, a team led by Gaël Dias (GREYC, with Youssef Chahir, Raphaëlle Lemaire, Jérémie Pantin, Alexis Lechervy, Azamat Kaibaldiyev, Fabrice Maurel) improves how machines separate what’s seen from what’s said in artwork descriptions—without needing images at deployment. Result: crisper classification of visual vs. contextual content in museum texts (Index 543).
  • Inside the university, syllabus plumbing gets smart. Wissal Essalah at LITIS UR shows how sentence embeddings and the ESCO skills graph can semi‑automate the thorny task of aligning cross‑cutting competencies with course outcomes—turning hours of faculty deliberation into a transparent, reproducible matching step (Index 50).
  • And in high‑energy physics, self‑supervision goes mainstream. Antonin VacheretLPCC) and Frédéric Jurie, Guillaume Letellier (GREYC) unveil JP‑JEPA, a foundation model that learns jets from raw particles, resists detector quirks, and competes with fully supervised rivals using fewer labels—a playbook for robust science at collider scale (Index 1935).

  • Across western France, mud remembers—and it dates itself. Using ultra‑bright quartz OSL, a team led by Meryem Mojtahid at Morphodynamique Continentale et Côtière (M2C) clocks rapid estuary infilling—up to 6 cm per year in the Loire—while calling out radiocarbon pitfalls in restless tidal channels. The punchline: human works and warming are rewriting geomorphology on human timescales (Index 1238).
  • Zooming into two hypertidal mouths (Orne and Somme), Laurent Dezileau and M2C partners braid maps, cores and geochemistry to show how tide, sediment hunger and engineering produce distinct but converging estuary trajectories. Managing one‑size‑fits‑all won’t cut it—site‑specific fingerprints matter (Index 1239).
  • On Cuba’s fossil reef staircases, Leandro Peñalver‑Hernández and collaborators at M2C use in‑situ 36Cl to quantify how fast carbonate coasts wear down. Beaches act as living shields for low terraces; older surfaces weather more and faster—hard numbers that help separate storm scars from slow creep (Index 1237).
  • As offshore wind rises, anticorrosion systems meet ecology. The ECOCAP project led by Christelle Caplat (BOREA) tests metal‑rich plumes from galvanic anodes on crustaceans, coupling acute and chronic exposures across life stages. Bottom line: quantify cocktail effects early, so protection at sea doesn’t become pollution at sea (Index 623).
  • Deep corals, deep time—now in a tank. Lenaick Menot and the BOREA team build pressure‑controlled mesocosms for long‑term coral experiments under realistic cold, dark, acidic futures. Continuous flow, isobaric feeding, and clear viewports bring reef resilience science from abyss to bench (Index 1767).

  • When molecules get bulky, classic zeolites choke. Enter extra‑large‑pore frameworks. Lu Lin and a global team at Laboratoire Catalyse et Spectrochimie (LCS) chart how 3D megapore architectures bridge micro‑ and meso‑porosity, unlocking greener catalysis and separations—while flagging costs, defects and the need for ML‑guided design (Index 1459).
  • Inside a single SAPO‑34 crystal lies a city of differences. Using etching, multiscale imaging and advanced NMR, Jing Niu and Svetlana Mintova at LCS map zones of defects, silicon, intergrowths and reactivity. These hidden districts steer selectivity and coke in methanol‑to‑olefins, turning “imperfections” into design knobs (Index 1980).
  • ZEO‑1, the poster child of extra‑large pores, gets a recipe book. Dongyue Wang and co‑authors at LCS show how swapping phosphonium templates—and toggling hydroxide vs. “deficient fluoride”—tunes particle size, acidity and active‑site distribution. Same framework, different personalities (Index 1463).
  • Power‑to‑ammonia under mild conditions? Sabrina Akrour, Cyril Thomas, Alexandre Vimont and Guylène Costentin at LCS boost Ru electron density with basic hydroxyapatite supports, enabling greener NH3 synthesis and practical hydrogen storage without furnace‑level pressures (Index 1464).
  • And for oxygen evolution, interfaces win games. André Olean‑Oliveira and colleagues at Groupe de Physique des Matériaux (GPM) anneal amorphous high‑entropy nanoalloys into interface‑rich heterostructures, harnessing metastability to light up OER performance (Index 2144).

  • In sight‑threatening fungal endophthalmitis, the retina speaks in patterns. Across 8 centers, Salil Mehta and an international team with COMETE show that OCT features—lesion size, satellite dots, hemorrhage/vasculitis, choroidal changes—separate Candida from Aspergillus with ~85% ML accuracy, guiding therapy while cultures lag (Index 1823).
  • At lymphoma diagnosis, pixels predict. In primary mediastinal B‑cell lymphoma, Fabrice Jardin and collaborators (CBG, GPMCND, IRIB) find that PET‑derived tumor volume and dispersion metrics (TMTV, Dmax, medPCD) form a 3‑parameter radiomic score that outperforms clinical risk factors for overall survival (Index 1857).
  • Surgeons need simple, strong signals. The 4‑item AFC score—validated by Yves Panis, Arnaud Alvès, Eric Vicaut, Fabrice Kwiatkowski, Karem Slim, Georges Mantion at ANTICIPE—predicts postoperative mortality after colorectal resection, turning pre‑op data into clearer conversations at the bedside (Index 459).
  • Public health needs clean numbers. A France‑Ireland‑Germany team led by Mari‑Vorgan Louyer (ANTICIPE) shows commercial ELISAs overestimate low urinary glyphosate and lack repeatability versus MS/MS. Takeaway: use mass spectrometry for non‑occupational exposure levels to avoid false alarms (Index 350).
  • Even contact lenses get a digital twin. Laure Adam and co‑authors at LCS couple corneal metabolism with oxygen transport to show how scleral lens clearance, permeability and decentration shift the cornea from aerobic to anaerobic—and how smarter designs can curb swelling (Index 1465).
