Music


The music of the silks

Researchers synthesize a new kind of silk fiber --- and find that music can help fine-tune the material’s properties

This diagram of the molecular structure of one of the artificially produced versions of spider silk depicts one that turned out to form strong, well-linked fibers. A different structure, made using a variation of the same methods, was not able to form into the long fibers needed to make it useful. Musical compositions based on the two structures helped to show how they differed. (Credit: Markus Buehler/MIT)
Research by MIT’s Markus Buehler — together with David Kaplan of Tufts University and Joyce Wong of Boston University — has synthesized new variants on silk’s natural structure, and found a method for making further improvements in the synthetic material.
The work stems from a collaboration of civil and environmental engineers, mathematicians, biomedical engineers and musical composers. The results are reported in a paper published in the journal Nano Today.
“We’re trying to approach making materials in a different way,” Buehler explains, “starting from the building blocks” — in this case, the protein molecules that form the structure of silk. “It’s very hard to do this; proteins are very complex.”/.../
