Today it was announced that scientists in the Francis Crick Institute in the UK would be allowed to use CRISPR-Cas9 technology to edit the genome in human embryos. There has been a lot of controversy surrounding CRISPR technology (apart from patent rights and giving proper credit, there have been lots of ethical issues with the technology) especially when one Chinese group used the technology (perhaps prematurely) to edit human embryos. This time, the scientists, led by Kathy Niakan, have received official permission from the UK Human Fertilisation and Embryology Authority (HFEA) to be able to conduct their research. The main interests in their research revolve around infertility. For more information, check out Nature News.
