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.

Congress will leave in place a ban on genetically modified human embryos, despite a push to overturn it, Stat News reports.

Where it stands: Since 2015, Congress has effectively banned a procedure that combines genetic material from a mother, father and female donor.
