  • High-resolution imaging is essential for quantum simulation and computation in optical lattices and tweezers. Here, authors achieve fast 2.4-microsecond single-atom imaging with 99.4% fidelity and demonstrate number-resolved imaging without parity projection, advancing quantum readout capabilities.

  • The realization of dipolar quantum solids with an ultracold gas of magnetic atoms in an optical lattice ushers in quantum simulation of many-body systems with long-range anisotropic interactions.

  • Autoreactive T cells are normally eliminated during their maturation in the thymus, but an unknown number of autoreactive CD4+ T cells escape to the periphery. Here the authors show, by comparing the T cell receptors of mice sufficient or deficient in CD4+Foxp3+ regulatory T (Treg) cells, that autoreactive and potentially pathogenic clones account for approximately one-third of the peripheral repertoire of CD4+Foxp3– cells.

  • Whether differentiation of regulatory and conventional T cells in the thymus requires similar T-cell receptor affinity is not known. Here, the authors show that cells expressing the same T-cell receptor selected on the same ligand can give rise to both lineages, but different sensitivity to negative selection separates their T-cell receptor repertoires.

  • By using high-throughput sequencing of T-cell receptors, this study shows that thymus-derived regulatory T (Treg) cells constitute most Treg cells in all lymphoid and intestinal organs, including the colon, suggesting that thymic Treg cells and not induced Treg cells dominantly control tolerance to the gut’s antigens such as commensal microbiota.
