The standard model of modern cosmology might be cracked by the recent persistent hot debate on the Hubble-constant(H_(0))tension,which manifests itself as the sound-horizon(r_(s))tension or absolute-magnitude(m_(B))tension if deeming the origin of the Hubble tension from modifying the early or late Universe,*** this study,we achieve a fully model-independent constraint(fitting a model-independent global parameterization to a model-independent inverse distant ladder with a modelindependent high-redshift calibration)on late-time models with strong evidence against homogeneous new physics over theΛ-cold-dark-matter(ΛCDm)*** using this model-independent constraint to calibrate sufficiently local supernovae with corresponding late-time models extrapolated below the homogeneity scale,we find surprisingly that,although both H_(0)tension and mB tension are absent in our local Universe,a combination of H_(0)and m_(B)as the intercept a B of the magnitude-redshift relation exhibits 3~7σtension even for theΛCDm *** aBtension seems to call for local-scale inhomogeneous new physics disguised as local observational systematics.

Zinc homeostasis plays an essential role in maintaining immune function and is tightly regulated by zinc transporters. We previously reported that the zinc transporter SLC39A10, located in the cell membrane, critically regulates the susceptibility of macrophages to inflammatory stimuli; however, the functional role of SLC39A10 in T cells is currently unknown. Here, we identified two SNPs in SLC39A10that are associated with inflammatory bowel disease(IBD). We then generated transgenic mice with T cell-specific deletion of Slc39a10(cKO) and found that its loss not only protects against disease progression in IBD and experimental autoimmune encephalomyelitis(EAE),but also induces massive apoptosis via a p53/p21-and Bcl2-independent process. mechanistically, we show that Slc39a10 serves as a key zinc importer upon activation of T cell receptor to safeguard DNA replication. Together, these findings provide new mechanistic insights and potential targets for the development of new therapeutic strategies for the treatment and/or prevention of T cell-mediated autoimmune diseases.
