Ep 1. Spider Thread

Innovation Nation season 6 episode 1, titled "Spider Thread," explores the innovative and life-changing technology of spider silk. Host Mo Rocca takes viewers on a journey to learn how this strong, lightweight material is being used in a variety of industries, from medicine to fashion.

The episode begins with a visit to a company called Bolt Threads, where scientists have found a way to recreate spider silk using genetically-engineered yeast. This method allows them to mass-produce the silk, which has the potential to replace materials like polyester and nylon. The silk is stronger than steel, yet much lighter, and can be used in everything from athletic wear to car parts.

Next, Rocca meets with the founder of Spiber, a Japanese company that is also developing spider silk using a similar method. He learns how the company is looking to take advantage of the material's unique properties in the field of medicine, where it could be used to create artificial tendons and ligaments.

The episode also explores how spider silk is being used to help protect soldiers. Rocca visits the U.S. Army Research Laboratory to see how scientists are creating a new type of body armor using the material. The spider silk-based armor is not only stronger than Kevlar, but also lighter and more flexible, which allows soldiers to move more easily in the field.

In addition to its strength and light weight, spider silk also has fascinating adhesive properties. Rocca meets with researchers at the University of Akron who are studying how spiders are able to cling to surfaces, even upside down. This research could lead to the development of new adhesives and coatings for a variety of applications.

Finally, the episode takes a look at the art world, where spider silk is being used in a unique way. Rocca visits a fashion designer who has created a new type of fabric using silk produced by Golden Orb spiders. The fabric is incredibly delicate and beautiful, and is being used to create one-of-a-kind dresses and textiles.

Overall, Innovation Nation season 6 episode 1 offers a fascinating look at the cutting-edge technology behind spider silk, and how it is being used to solve real-world problems in a variety of fields. From medicine to fashion, this innovative material has the potential to revolutionize the way we live and work.
