Sticky mussel threads could have medical applications

Telegraph : Marine mussels attach themselves to rocks and other surfaces with a network of what are called byssus threads. In a study published in Nature Communications, researchers discuss the secret behind the strength of the filaments. They are composed of a protein that forms both stiff and stretchy threads in a 4:1 ratio. As a result, the byssus works like a bungee cord to rapidly dissipate the impact energy generated as the mussels are battered by ocean waves. The unique properties of an organic material that combines stiffness and stretchiness could be applied in medicine for repairing damaged bones or as surgical sutures in blood vessels.
