The secret of resistance—shattering into a thousand pieces

Being all in one piece is not always a good strategy for resisting external strain. Biological tissues are well aware of it: they tend to crack simultaneously and gradually in several places, rather than catastrophically in one place only. This makes them particularly resistant. A group of SISSA researchers conducted a theoretical study that explains the mechanism underlying this phenomenon, which was experimentally observed in epithelial cell cultures. By doing so, they take their first steps towards creating artificial materials with features inspired by biomaterials. Materials of this kind may have a number of applications, for example in the medical field. The study has just been published in Physical Review Letters.
