    Creation of bioinspired ion channels that separate ions without compromising selectivity, conductivity or rectification ability has long been a challenge. Integration of metal–organic frameworks into asymmetric nanopore membranes overcomes this limitation.

    Two initially neutral conjugated semiconducting polymers are found to transfer electrons when put in contact in the solid state, leading to mutual electrical doping.

    Reprogramming normal cells into tumour precursors involves complex reconditioning of the tissue microenvironment. Cumulative integration of genetic drivers with extrinsic mechanical inputs is now shown to engage YAP/TAZ to rewire cell mechanics and initiate tumorigenic reprogramming.

    NiCoFeGa single crystals exhibit large non-hysteretic superelasticity over broad temperature and composition ranges. It is attributed to the continuous phase transition with applied stress, which is related to the fluctuation of entangled ordered and disordered crystal structures.

    Dendrite formation during electrodeposition while charging lithium metal batteries compromises their safety. Solid-ion conductors are now designed with a universal chemomechanical approach, resulting in either pressure- or density-driven dendrite-suppressing properties.

    Here, using an interfacial growth strategy, UiO-66 MOF nanocrystals are asymmetrically embedded into conical pores in a polymer membrane. These pores have a mono/divalent cation selectivity of 103, which can be tuned by pH, and act as ionic rectifiers.

    Receptor tyrosine kinase (RTK)–Ras oncogenes have now been shown to reprogram normal primary human and mouse cells into tumour precursors by empowering cellular mechanotransduction, in a process requiring permissive extracellular-matrix rigidity and intracellular YAP/TAZ/Rac mechanical signalling sustained by activated oncogenes.
