Brûlures d’estomac : des chercheurs explorent une piste inattendue pour protéger l’œsophage

Un reflux gastro-œsophagien mal contrôlé peut, à long terme, favoriser l’apparition d’un cancer de l’œsophage. Mais des chercheurs américains viennent de mettre en lumière une approche aussi surprenante que prometteuse : l’utilisation de probiotiques pour limiter l’inflammation, réparer les...

Pigeons May Sense Earth’s Magnetic Field Using Superparamagnetic Immune Cells in Their Livers

Lisowski et al. used physical, morphological, functional, and genomic assays to identify the presence of superparamagnetic macrophages in the liver of homing pigeons (Columba livia domestica). Image credit: Spanishguitar101 / CC BY-SA 4.0.

Scientists have identified supermagnetic macrophages in the livers of homing pigeons (Columba livia domestica) that appear essential for navigation when the Sun is not visible, pointing to an entirely new mechanism for animal magnetoreception.
