Researchers link patterns seen in spider silk, melodies (MIT)

Using a new mathematical methodology, researchers at MIT have created a
scientifically rigorous analogy that shows the similarities between the
physical structure of spider silk and the sonic structure of a melody, proving
that the structure of each relates to its function in an equivalent way.

The step-by-step comparison begins with the primary building blocks of each
item — an amino acid and a sound wave — and moves up to the level of a beta
sheet nanocomposite (the secondary structure of a protein consisting of
repeated hierarchical patterns) and a musical riff (a repeated pattern of
notes or chords). The study explains that structural patterns are directly
related to the functional properties of lightweight strength in the spider
silk and, in the riff, sonic tension that creates an emotional response in the
listener.

While likening spider silk to musical composition may appear to be more
novelty than breakthrough, the methodology behind it represents a new approach
to comparing research findings from disparate scientific fields. Such
analogies could help engineers develop materials that make use of the
repeating patterns of simple building blocks found in many biological
materials that, like spider silk, are lightweight yet extremely failure-
resistant. ...
