Solving the riddle of nature’s perfect spring

Solving the riddle of nature’s perfect spring
Scientists have unravelled the shape of the protein that gives human tissues their elastic properties in what could lead to the development of new synthetic elastic polymers.

University of Manchester researchers, working with colleagues in Australia and the United States, used state-of-the-art techniques to reveal the structure of tropoelastin, the main component of elastin.
Elastin allows tissues in humans and other mammals to stretch, for example when the lungs expand and contract for respiration or when arteries widen and narrow over the course of a billion heart beats.
