Expanding upon previous projects that laid the foundation for making music from amino acid chains, MIT scientists can now use their process to create never-before-seen proteins—especially ones with beneficial properties. Using amino acids as notes, and artificial intelligence to turn them into chords, scientists can craft proteins based on frequencies and patterns that they can hear, and lean into rhythms or loops that lend proteins preferable traits. This would assist in making synthetic versions of naturally-available materials better and ultimately easier to invent. Spider silk, for instance, is a material that’s stronger than steel and kevlar, and could have antimicrobial properties.
