#CRISPR

Going beyond genetic letters, the results could transform medicine. Thanks to increasingly efficient and affordable gene sequencing technologies, we can now chart our genetic blueprint in unprecedented detail. But what does each gene do? Of the roughly 20,000 genes that encode proteins,

The new tool, NanoCas, could extend gene therapies throughout the body. When the gene editing tool CRISPR-Cas9 rocketed to fame more than a decade ago, it transformed biotechnology. Faster, cheaper, and safer than previous methods, the tool helped scientists gain insight into gene functions—and
