  • Incoherent optical spatial solitons are self-trapped beams with a multimodal structure that varies randomly in time. All incoherent solitons observed so far have been supported by nonlinearities with slow response times. Here, Segev and colleagues demonstrate such solitons in nonlinear media with fast (essentially instantaneous) response times and show that new physical features appear.

  • Electron-chirality interactions affect charge and spin transport in chiral conductors. Here, the authors show that helicene-based single-molecule junctions behave as a magnetic-diode and spin-valve device, enabling the identification of an atomic-scale coexistence of different electron-chirality interactions.

  • The conductance of single-molecule junctions based on oligoacenes is shown to saturate when the molecule length increases. The saturation trend depends on the frontier orbitals of the metals used and on their hybridization with molecular π-orbitals.

  • Magnetic effects can emerge due to structural variations when the size of materials is reduced towards the nanoscale. Here, Chakrabarti et al demonstrates the opposite effect, showing that the interatomic distance in atomic wires changes by up to 20% depending on the orientation of an applied magnetic field.

  • Chronic UV exposure has been associated with immune system suppression. Here the authors show that enhanced tumor growth and resistance to PD1 blockade in mice exposed to UV irradiation is associated with induced expression of Ly6a in CD8 + T cells and that targeting Ly6a enhances anti-tumor immune responses in models resistant to anti-PD1.

  • Quantum interference can be used to control electronic transport with high sensitivity at the nanoscale. Pal et al. show that without the need for magnetic materials, quantum interference can also filter spin transport approaching the limit of ideal spin-polarized ballistic transport in molecular junctions.

  • Building on a pre-existing pooling pipeline for the efficient detection of SARS-CoV-2, the results of a large-scale implementation study show the feasibility and benefits of saliva sample pooling to enhance neonatal screening for congenital cytomegalovirus.

  • New data from a large healthcare organization in Israel reveal a reduction in new infections in an unvaccinated population in communities with rapid vaccination rollouts, suggesting that mass vaccination strategies confer cross-protection of unvaccinated individuals.

  • Activating mutations in Interleukin-7 receptor alpha (IL7Ra) have been reported in B-cell precursor acute lymphoblastic leukaemia (BCP-ALL) but its role in leukaemogenesis is not clear. Here, the authors show that activation of IL7Ra in primary human hematopoietic progenitors initiates preleukaemia and cooperates with CDKN2A silencing to develop BCP-ALL.
