This week on The Naturalist Bernie sits down with Alex Bolesta, Ariana Rickard, Chin-Li Yan, and Pierre Bull for a discussion on silk and the incredible creatures that make them: silk worms. The secret of silk's origin was kept secret for literally thousands of years, and not without purpose, for silk is stronger and tougher than tensile steel, and a piece of silk the size of a pencil could hold a 747. Tune in for a group discussion on how a tiny little worm can build fortunes and yet is still kept as pets in China. This episode was sponsored by Fairway: like no other market.
