Engineers solve the paradox of why tissue gets stiffer when compressed

Tissue gets stiffer when it’s compressed. That stiffening response is a long-standing biomedical paradox, as common sense dictates that when you push the ends of a string together, it loosens tension, rather than increasing it. New research explains the mechanical interplay between that fiber network and the cells it contains.
