"Justin Jones, a biologist who engineers spider silks at Utah State University but who was not involved with the research"
The material, described today in Matter, is “a really high-performance fiber,”
Jones says it’s surprising that the MiSp-based fibers were so flexible. This protein typically makes for strong, but not stretchy, fibers, he says. “But it does make a flexible fiber when you put it in a silkworm.”
Jones notes it could be challenging to protect intellectual property rights when commercializing the spider silk because it would likely entail distributing transgenic silkworm eggs to many farmers.
It also remains to be seen, he says, whether the inserted genes will persist when the silkworms are bred
