The Silklab at Tufts University has pioneered the use of silk as a biological solution for many technological challenges. Just like the silk that goes into fine fabric, the silk used in the lab comes from the cocoons of silkworms, but it is processed in a very different way to break it down to its fibrous protein base. Tufts researchers have formed that base into all sorts of useful materials, from faux leather to optical sensors to glue that can be used underwater.
