**New CRISPR-Cas9 System Achieves Simultaneous, Targeted Cell Engineering**

Researchers have developed a novel CRISPR-Cas9 system capable of performing multiple, distinct cell engineering tasks simultaneously. This new system, referred to as a polyfunctional editor, expands the capabilities of CRISPR-Cas9 technology by enabling researchers to target and modify different cellular functions at the same time.

The study, published in *Nature Communications*, details how the polyfunctional editor works by delivering multiple guide RNAs and Cas9 enzymes to a cell. Each guide RNA directs a Cas9 enzyme to a specific DNA sequence, allowing for the simultaneous editing of multiple genes or the introduction of different genetic modifications. Researchers demonstrated the system’s effectiveness by simultaneously knocking out one gene and inserting a new gene into a different location within the cell’s genome. This advancement overcomes limitations of previous CRISPR-Cas9 methods, which typically focus on editing a single target at a time. The polyfunctional editor holds promise for accelerating research in areas such as gene therapy, drug discovery, and synthetic biology.
