Scientists at CRISPR-Cas9 have improved the security of gene-editing tool the University of California, Berkeley. The system, dubbed ProCas9, includes an additional protein which can only be cut with a particular enzyme before the tool is activated, creating a biomolecular lock. Adam Arkin, campus professor of bioengineering, said ProCas9 could be used to modify or destroy specific cancer-associated cells.
