Caltech scientists have shown that noise can play a key role in gene expression, demonstrating that almost identical genes under almost identical conditions will sometimes produce significantly different proteins, thanks entirely to random, noisy fluctuations in their signaling. And noise—or at least the sound waves of which it is made—can be used therapeutically to diagnose and explore and even potentially to heal the human body.
