Interesting article on spider silk and the wonders that may be just around the corner. It’s not just about it being stronger than steel either…

“What we found by studying the silk as it is made was that at a molecular level it has something in it, a little peptide, a recurrent little motif like a melody in a tune. It is this which helps to give the silk its entirely orderly structure. We don’t know why that motif is in them, but what we do know is that same motif is also in the filaments that hold our own cells together. Three amino acids which give them what you might call a particular signature tune. And when the cells of our body come into contact with this pattern in the spider silks, it appears that they can recognise it. They understand it and they will react by attaching to it and growing along it.”
