Dry solution to a sticky problem
Sticking plasters revolutionized the protection of minor wounds, but they're not ideal for fragile skin. A material that mimics the adhesive properties of certain beetles' feet might provide a solution.

Nanoscale chemical tomography of buried organic–inorganic interfaces in the chiton tooth
Many biomineralized tissues (such as teeth and bone) are hybrid inorganic–organic materials whose properties are determined by their convoluted internal structures. Now, using a chiton tooth as an example, this study shows how the internal structural and chemical complexity of such biomaterials and their synthetic analogues can be elucidated using pulsed-laser atom-probe tomography.

Designed biomaterials to mimic the mechanical properties of muscles
Here, artificial proteins are described that mimic the molecular architecture of titin — a protein that helps to govern the passive elastic properties of muscle. The new artificial proteins combine structured and unstructured domains, and can be photochemically crosslinked into a solid biomaterial that is resilient at low strains and extensible and tough at high strains. This provides an example of tailoring the macroscopic properties of a material through engineering at the single-molecule level.

Muscle mimic
An elastic polymer has been made whose molecular structure mimics that of titin, a protein found in muscle. The resulting material is tough, stretchy and dissipates energy — just like muscle itself.
