Just like with spider-silk, researchers seem to have found a way to make resilin, an elastic protein used by various insects:
Where are the most promising industrial or non-medical applications? Just better basketballs and tennis balls? Or can it do tires too? (ie. does it have toughness, or just the elastic resilience?)
Since nanotubes are drawing away some of the interest in spider silk, will they do the same with resilin, or is there some other promising molecule that will do this?
