Researchers at the University of Bayreuth have recently successfully bred the world’s first CRISPR-Cas9-modified spider to produce red fluorescent silk. For this work, they used a species of ...

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.
