In a recent paper in Nature, Bernatz and colleagues report a measure of the health of the thymus — an organ in the chest that produces T cells. The researchers derived a ‘thymic health’ score from an analysis of computed tomography (CT) images, and showed that a low score was associated with mortality and several disorders (S. Bernatz et al. Nature 652, 986–994 (2026); see also G. Anderson Nature 652, 865–866; 2026).
