Chinese researchers used CRISPR technology to safely treat a man with cancer and HIV, Bloomberg reports, a major step forward for the gene editing field.

Why it matters: "The man's medical case, published Wednesday in the New England Journal of Medicine, is the first detailed report in a major academic journal of how doctors are using the experimental tool [CRISPR] to manipulate the DNA of a living patient in an effort to cure disease," Bloomberg writes.

Research deepens on using "jumping genes" in CRISPR therapy

Two prominent teams of scientists recently announced transposons — or "jumping genes" — can improve the precision of CRISPR gene editing.

Why it matters: While this research is still in early stages, as both teams tested their techniques on bacterial cells, experts say the technique could allow edited genes to be more precisely inserted into genomes, possibly addressing concerns with current CRISPR systems that can lead to off-target editing and random deletions or even cancer.
