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 ...

For the first time, researchers have created a gene-edited spider that spins red fluorescent silk. Led by a team at the University of Bayreuth, the project tackled a long-standing challenge in ...

Researchers have, for the first time ever, used CRISPR gene editing on spiders. While the genetically-modified critters lack the ability to give you spidey senses, they do spin glowing silk.

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.

Apart from turning their silk bright red, the researchers also attempted to knock out a gene called sine oculis, which is responsible for the development of spider eyes.
