  • Ferumoxytol (Fer) is an FDA-approved iron oxide formulation that disrupts caries-causing biofilms with high specificity but cannot interfere with enamel acid demineralization. Here, Fer is combined with stannous fluoride (SnF2), resulting in enhanced stability of SnF2 and inhibition of both biofilm accumulation and enamel damage more effectively than either alone.

  • Super engineering plastics that utilise bio-derived cyclic monomers rarely offer the same thermal/mechanical properties, scalability and recyclability as petrochemical derived plastics. Here the authors use a phase transfer catalyst to synthesise a transparent, recyclable and tough isosorbide-based polymer with a high molecular weight.

  • Self-healing materials strive to emulate curable and resilient biological tissue but their performance is often insufficient for commercial applications because self-healing and toughening are mutually exclusive properties. Here, the authors report a tough and strong carbonate-type thermoplastic polyurethane elastomer that self-heals at ambient temperature.

  • Biological tissues are extremely water rich but remain mechanically stiff, behaviour that is difficult to recapitulate in synthetic materials. Here the authors design a hydrogel/sponge hybrid material driven by a self-organized network of cyano-p-aramid nanofibres that combines these properties for biofunctional materials.

  • Using VR, EEG, and contrastive learning, this study found that subjective awe is better predicted by behavioral and neural representations of mixed feelings than by those of purely positive or negative ones, challenging a univalent viewpoint of awe.

  • Bioplastics are yet to replace commodity plastics. In this Review, we address the barriers faced by bioplastics to obtaining standard labels and certificates and we propose pre-screening methods to optimize these processes. Challenges in production, consumption and disposal are also discussed.

  • The interfaces linking biological tissues and man-made devices is challenging due to mechanical mismatch, biofouling, and water content. Soft materials such as hydrogels have emerged in diverse applications, however, their unresolved problem is the loss of functions in a short period. This report explores natural connective tissue, called periostracum, which is perfectly bridged between biological tissue and inorganic nonliving shell with high durability for long-lasting functions. Its hierarchically designed strategy provides a novel blueprint to design durable soft materials for the interfacing device into tissue.
