Water may play critical role in how our tissues stretch and spring back

Every time your heart beats, your lungs expand, or your skin stretches, a remarkable protein called elastin helps your body return to its original shape. But what exactly gives this protein its elasticity? For more than 50 years, scientists have debated whether elastin's ability to stretch and recoil comes primarily from the protein's own flexibility or from its interactions with surrounding water molecules.
