Goats are making silk stronger than steel, and we see opportunity. In this video about synthetic biology, Fidelity analyst Robert Chan explains why.

So what is synthetic biology? It's an approach to creating new organisms that fulfill specific functions, using nature as a manufacturing platform and DNA as the raw material. To date, scientists have created goats making spider silk in their milk (it's five times stronger than steel), salmon that grow twice as fast as normal, and bacteria that produce anti-malarial drugs and biodiesel. Each invention could radically increase the supply of these vital products.

As the science evolves -- it is still in a very early, experimental phase -- synthetic biology could become the defining technology of the 21st century, bringing with it new thinking, new questions, and new opportunities.
