  • Downsizing into the strong confinement regime can improve single-photon purity in quantum dot emitters, but often at the expense of optical stability. Here, the authors present an alternative approach leveraging electron–phonon coupling to achieve stable, room-temperature single-photon emission with enhanced purity in colloidal hybrid lead halide perovskite quantum dots.

  • A quantitative morphological framework for the human thymus reveals the establishment of the lobular cytokine network, canonical thymocyte trajectories and thymic epithelial cell distributions in fetal and paediatric thymic development.

  • Greatly enhanced light absorption is reported in large perovskite quantum dots by realizing a transition with a giant oscillator strength at the optical bandgap.

  • Colloidal perovskite quantum dots hold promise for polaritonic devices with strong excitonic confinement. Here the authors report the observation of room-temperature cavity exciton-polariton condensation in a perovskite-based quantum dot solid, opening the door towards quantum and photonics applications.

  • Phospholipids enhance the structural and colloidal integrity of hybrid organic–inorganic lead halide perovskites and lead-free metal halide nanocrystals, which then exhibit enhanced robustness and optical properties.

  • Excitonic single-photon superradiance is reported in individual perovskite quantum dots with a sub-100 ps radiative decay time, almost as short as the reported exciton coherence time.

  • Narrow emission is desired for light-emitting devices. Here, Kovalenko et al. demonstrate that the emission line-broadening in perovskite quantum dots is dominated by the coupling between excitons and surface phonon modes which can be controlled by minimal surface modifications.

  • The gut microbiome can change with age and influence aging-related diseases systemically, including in the brain. The authors show that rejuvenation of the gut microbiome by fecal microbiota transplantation from young mice reverses aging-induced deficits in the hippocampal immune system, metabolome and transcriptome, and rescues selective cognitive deficits.
