While DNA may be the blueprint of life, proteins are the workhorses, says Polly Fordyce, a bioengineer, explaining how one of her favorites, kinesin, “walks” in 8-nanometer steps transporting chemical cargo through the body.

More remarkable still, Fordyce says, kinesin is just one among thousands of “incredible” proteins that make life happen, as she tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
