  • Hydration frustration — such as burying polar residues or exposing hydrophobic ones — is a hallmark of protein chemistry and critical for biological functions. Now, such frustration can be designed using synthetic copolymers, without the need for defined sequence or structure.

  • Despite the high incidence and mortality rates of hepatopancreatobiliary cancers in the African continent, epidemiological and clinical data are scarce. This Roadmap article describes the efforts of the Africa HepatoPancreatoBiliary Cancer Consortium to establish cancer registries in the region.

  • The directed self-assembly (DSA) of block copolymers (BCPs) has shown great promise in fabricating customized two-dimensional (2D) geometries at the nano- and mesoscale. Here, the authors report the discovery of spontaneous symmetry breaking and superlattice formation in DSA of BCP.

  • This study reports the preparation of degradable poly(β-amino ester) microparticles as a promising replacement for nondegradable microplastics in cleansing products and food fortification, demonstrating effective cleansing, toxic element removal and robust nutrient protection with efficient release.

  • Sparse templates can be used to direct the assembly of block copolymers into patterned structures. Here the authors report a small set of template tiles that can be combined in different arrangements and orientations to form a variety of non-trivial patterns.

  • Physics out-of-equilibrium is necessary to understand a variety of interactions, for example in biological systems. Here, the authors show that the interactions between non-Brownian active spinning particles can change from repulsive to attractive depending on the properties of the surrounding passive medium.

  • Blood clotting is caused by biopolymer-mediated aggregation of platelets and is enhanced by fast shear flows. Chen et al. find a similar process that arises during the self-assembly of polymer–colloid composites—a process that can be controlled and even reversed by flow rate and interparticle interaction.

  • Block copolymer self-assembly can successfully generate monolayers of complex nanopatterns. Here, the authors orthogonally self-assemble 2 or 3 layers of distinct molecular weight block copolymers, and fabricate complex nanomesh structures without alignment or high-resolution lithographic templating.

  • The accessibility of catalytically active sites in enzymes is maintained by the surrounding amino acid residues, but in synthetic metal clusters, these sites are typically blocked by the organic groups used to coat them. It has now been shown that the accessibility of gold clusters bound by calixarenes can be controlled by tuning the relative sizes of the metal cores and the ligands.
