Nearly seven years ago, MIT scientists mapped the molecular structure of proteins in spider silk threads onto musical theory to produce the “sound” of silk in hopes of establishing a radical new way to create designer proteins. That work even inspired a sonification art exhibit, “Spider’s Canvas,” in Tokyo last fall. Artist Tomas Saraceno created an interactive instrument inspired by the web of a Cyrotophora citricola spider, with each strand in the “web” tuned to a different note.
Now MIT materials engineer Markus Buehler and his colleagues are back with an even more advanced system of making music out of a protein structure—and then converting it back to create novel proteins never before seen in nature. The team also developed a free app for the Android smartphone, called the Amino Acid Synthesizer, so users
