Cas9 senses CRISPR RNA abundance to regulate CRISPR spacer acquisition

Prokaryotes create adaptive immune memories by acquiring foreign DNA snippets, known as spacers, into the CRISPR array1. In type II CRISPR-Cas systems, the RNA-guided effector Cas9 also assists the acquisition machinery by selecting spacers from protospacer adjacent motif (PAM)-flanked DNA2,3. Here, we uncover the first biological role for Cas9 that is independent of its dual RNA partners. Following depletion of …

CRISPR can stop malaria spread by editing a single gene in mosquitos

CRISPR gene-editing therapy has shown great potential to treat and even cure diseases, but scientists are now discovering how it can be used to prevent them as well. A team of researchers found a way to edit a single gene in a mosquito that prevented it from transmitting malaria, according to a paper published in Nature. These genetically modified mosquitos …
