Mutant worms engineered with spider genes spin silk six times tougher than bulletproof Kevlar


Researchers at China's Donghua University inserted spider genes into the DNA of silkworms resulting in worms that can spin fibers six times tougher than the bulletproof material Kevlar. They used the gene editing technology CRISPR to replace the silkworm gene that codes for its silk protein with one from a particular East Asian orb-weaving spider. — Read the rest
