Here, the authors use first-principles-based calculations to demonstrate the possibility of ferroelectric skyrmions in oxide nanocomposites.

Genomic and transcriptomic analyses of chronic lymphoproliferative disorder of natural killer cells identifies somatic gain-of-function mutations in the chemokine gene CCL22 with cell-extrinsic effects. Mutations caused biased signaling downstream of the G-protein-coupled receptor for CCL22 and deregulated interactions with the hematopoietic microenvironment.

The biogenesis and stereochemical origin of many natural products remain unknown. Now the biosynthetic pathway of brevianamide A is elucidated. An isomerase is discovered that can catalyse pinacol rearrangement without a cofactor and determine the stereochemistry of the bicyclo[2.2.2]diazaoctane ring.

Here, Kaiser et al. describe a murine pneumonia virus vectored vaccine expressing spike protein, and show that intranasal immunization of male rhesus macaques provides good mucosal and systemic immunogenicity and efficacy.

Optical clock networks have many applications from precision time keeping, sensing to fundamental physics. Here the authors demonstrate robust and free-space femtosecond time synchronization of optical clocks via a moving quadcopter.

MIND-DC was a randomized, placebo-controlled, phase 3 trial of adjuvant blood-derived natural dendritic cell (nDC)-based therapy in patients with stage III melanoma, showing that nDC-induced immune responses did not translate into survival benefit. Here the authors report that, despite randomization, baseline differences in fecal metagenomics and serum metabolomics profiles between treatment arms might have influenced the clinical outcome of the trial.

Here, the authors isolated and characterized genetic features of spike-specific monoclonal antibodies. They show how the antibodies evolve from infection to after vaccination and conclude that highly polyclonal repertoires of affinity-matured memory B cells are efficiently recalled by vaccination.

Owing to large exciton binding energy, quasi-2D perovskite is promising for light-emitting application, yet inhomogeneous phases distribution limits the potential. Here, the authors improve the performance by using MeS additive to regulate the phase distribution and to reduce defect density in the films.

Long-range magnetic order of quasiparticle doped holes is important for understanding the physics of cuprate superconductors, albeit difficult to probe in experiments. Ong et al. observe ferromagnetism of quasiparticle doped holes in a cuprate heterostructure and discuss implications for cuprates in the ground state.
