house spider and red silk. a) CRISPR gene editing components were b) injected into spiders, which edited genes in their oocytes to c) result in modified baby spiders.

Their offspring produced red fluorescent silk, showing that CRISPR-Cas9 can be used to alter silk proteins without affecting production. The results are good news for materials science research.

Researchers used the popular gene-editing technique CRISPR to modify the DNA sequences of house spiders, causing them to produce red fluorescent silk. Scientists are hoping that the US Navy and ...
