Channeling Spider-Man

What’s blue and red and webbed all over? Spider-Man: Homecoming, the latest installment of our favorite superhero film franchise. We often get compared to Spider-Man, and although we’re not superhuman, we share Peter Parker’s love of science and we’re using technology to make materials we think he’d be proud of. In fact, Spider-Man has been such an inspiration to... Read more »

On March 10, we launched the world’s first ever human-made spider silk consumer product, a knit silk necktie. Why a tie?

The Interwoven Paths of Tech and Textiles – Part 1

Bolt Threads lives at the intersection of the two seemingly disparate worlds: fashion and biotechnology. We realize that technology and textiles aren’t so different after all: in fact, they have a long history of intertwining. (For an excellent longread, check out Virginia Postrel’s essay “How Textiles Repeatedly Revolutionized Human Technology”) Stone Age clothes were pretty... Read more »

Why Making Spider Silk Is So Tricky – Part 2

Over the past few decades, a number of groups have tried to make spider silk via modern biotechnology techniques, but spider silk textile products still aren’t available for sale. Why not, and what are we doing differently? Engineering a silk-producing organism neatly sidesteps the obstacles we mentioned in the previous post, but the method has... Read more »
