The morphologies of biological materials, from body shapes to membranes within cells, are typically curvaceous and flexible, in contrast to the angular, facetted shapes of inorganic matter. An alternative dichotomy has it that biomolecules typically assemble into aperiodic structures in vivo, in contrast to inorganic crystals. This paper explores the evolution of our understanding of structures across the spectrum of materials, from living to inanimate, driven by those naive beliefs, with…

Influence of Pyruvic Acid and UV Radiation on the Morphology of Silica-carbonate Crystalline Biomorphs
In this work we report the effect of introducing pyruvic acid (PA) in the growing process of silica-carbonate biomorphs. Gas-diffusion and single-phase methods were performed, and different
What macromolecular crystallogenesis tells us – what is needed in the future
Although the general rules governing protein crystal growth are known and a diversified panel of crystallization methods is available, producing focused protein crystals remains challenging. In the
Wire cut of double-sided minimal surfaces
TLDR
The entire workflow from mathematical modeling to production involves no 3D models or CAD/CAM software and employs a general-purpose language (Java) to create machine instructions from the Weierstrass representation of minimal surfaces.
Introduction for bioinspiration
The articles published in this issue of Interface Focus form a very special contribution to the celebrations during 2015 of the 350th anniversary of the first scientific journal, Philosophical

DEFECTS AND TEXTURES IN CHOLESTERIC ANALOGUES GIVEN BY SOME BIOLOGICAL SYSTEMS
Many biological materials are polymerized analogues of cholesteric liquid crystals. The same types of defect occur both in cholesteric liquids and in these more or less solid biological systems.

We argue for a convergence of crystallography, materials science and biology, that will come about through asking materials questions about biology and biological questions about materials,
Hydrodynamics of soft active matter
TLDR
This review summarizes theoretical progress in the field of active matter, placing it in the context of recent experiments, and highlights the experimental relevance of various semimicroscopic derivations of the continuum theory for describing bacterial swarms and suspensions, the cytoskeleton of living cells, and vibrated granular material.
Self-Assembled Silica-Carbonate Structures and Detection of Ancient Microfossils
TLDR
Inorganic micron-sized filaments, whose microstucture consists of silica-coated nanometer-sized carbonate crystals, arranged with strong orientational order, are synthesized, demonstrating that abiotic and morphologically complex microstructures that are identical to currently accepted biogenic materials can be synthesized inorganically.

A satisfactory picture of the structure of liquids has lagged far behind that of other states of matter. Ever since the time of Euler in the eighteenth century or, in a more precise form, since that
Membrane geometry of “open” prolamellar bodies
TLDR
The “open” type of prolamellar body in etiplasts was examined by electron microscopy to characterise its three-dimensional organisation, which is like that of the cages of water molecules in type IV clathrate-hydrates, point group P6/mmm, but about two orders of magnitude larger.
Origin of icosahedral symmetry in viruses.
TLDR
This work presents a minimal model for equilibrium capsid structure, introducing an explicit interaction between protein multimers (capsomers) and shows that the model reproduces the main structures of viruses in vivo and important nonicosahedral structures observed in vitro.
