Des écureuils en quête d'immortalité ? Une équipe de chercheurs franco-canadiens vient de démontrer que les tamias rayés sauvages vivant dans le sud du Québec contredisent ce qu'on sait du processus de vieillissement cellulaire. 👉 iphc.cnrs.fr/actualite/les-…

#RésultatScientifique🔎 Chez les tamias rayés 🐿️ le processus de vieillissement cellulaire défie les connaissances acquises jusqu'ici : contrairement aux autres espèces étudiées, leurs télomères s’allongent avec l’âge. 🧬 ➡️ inee.cnrs.fr/fr/cnrsinfo/le… 📕doi.org/10.1111/mec.16…

New paper for Physiol_Evol_Behv rdcu.be/dp3Gw Striped mice reduce their brain size when it’s getting hot and food gets scarce. First study that found the Dehnel phenomenon in a rodent, in a subtropical climate, and in the southern hemisphere. (2023) Mammalian Biology

New study over 27 years on ground squirrels (125+ mothers, 450 litters) reveals high plasticity in reproductive vs. somatic efforts. Individual variation doesn't always align with population trends, challenging assumptions about animal life histories. cdnsciencepub.com/doi/abs/10.113…

Study on 137 little owls shows telomere length (TL) varies by sex, body condition, and hatching rank. Results highlight TL's role in conservation physiology. ecoevorxiv.org/repository/vie…
