Now, researchers had successfully gene-edited silkworms to produce spider silk that’s six times stronger than Kevlar, the material used in bulletproof vests. This heavy-duty fiber could one day be used for surgical sutures, wound dressings, armored vests and structural materials for vehicles. It could also one day serve as a greener alternative to synthetic materials, like polyester and nylon, which shed harmful microplastics and were derived from fossil fuels. Researchers recently described their process and findings in the journal Matter. To advance ecological civilization, developing sustainable, eco-friendly high-strength and ultra-tough alternatives to non-...
