British researchers are now allowed to genetically modify human embryos


In a landmark decision Monday, British researchers will be the first worldwide to edit human embryos for genetic research, The Guardian reports.
The Human Fertilization and Embryology Authority is allowing Kathy Niakan, a London stem cell researcher, to genetically modify embryos using CRISPR and study them for up to 14 days. The embryos, which come as donations from couples who had some leftover after undergoing in vitro fertilization, cannot be implanted in women.
The research is expected to help scientists understand what causes miscarriages and how to treat infertility.
