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 Air Force-funded research could lead to the development of new "supermaterials" TK, Fast Company reports. As detailed in a paper published in the journal Angewandte Chemie, a team of researchers at the University of Bayreuth, Germany, a team injected the eggs of unfertilized female spiders with a CRISPR-Cas9 solution to insert a gene sequence for a red fluorescent protein. After mating with males of the same species, the offspring produced […]
