A study biochemically and structurally characterizes a lanmodulin from Hansschlegelia quercus with an oligomeric state sensitive to rare-earth ionic radius.

Organ-like 3D cultures are advanced model system for biology and medicine limited by their uncontrolled cell self-assembly. Here, the authors develop a hydrogel-in-hydrogel bioprinting approach to dynamically control the growth landscape of a broad range of living 3D cell cultures.

Safe delivery of genes is needed for gene therapy. Here the authors build “artificial viral vectors” (AVVs) by engineering the well-characterised structural components of bacteriophage T4: the large capacity, all-in-one, multiplex, programmable, and phage-based AVV nanomaterials have potential for gene therapy.

Many diseases involve reduced or absent levels of a particular protein and would benefit from therapies that increase gene expression. In their Review, Khorkova et al. discuss the growing range of RNA-targeted therapies in development that aim to boost gene expression, including nucleic acid-based therapeutics targeting the complex regulatory network of non-coding RNA species.

Organic molecules and materials are generally insensitive or weakly sensitive to magnetic fields due to their small diamagnetic force. Here, the authors show a strategy to amplify the magnetic responsiveness of self-assembled peptide nanostructures by synergistically combining the concepts of perfect α-helix and rod-coil supramolecular building blocks
