Nature Nanotechnology, Published online: 29 September 2026; doi:10.1038/s41565-026-02280-4Four-inch rhombohedral-stacked boron nitride wafers are reproducibly synthesized through a step-templated interfacial epitaxy strategy, exhibiting high-density, fast-speed and non-volatile memory performances.

Latent HIV reservoirs evade both antiviral therapy and immune surveillance. Luo and colleagues develop a multifunctional fusion protein that couples reservoir reactivation with targeted immune engagement and clearance, offering a coordinated strategy to expose and eliminate persistent HIV-infected cells.
