Scientists have successfully synthesized spider silk using genetically modified silkworms, creating fibers with a toughness six times superior to that of Kevlar, a material prominently used in bulletproof vests. This revolutionary work is the first to fabricate full-length spider silk proteins through silkworms, presenting a methodology that might give rise to an eco-friendly substitute to prevalent synthetic commercial fibers such as nylon. Tackling synthetic fiber issues Synthetic fibers like nylon have been widely used, but they pose environmental concerns due to their ability to release detrimental microplastics...
