Scientists in the U.K. have been given the green light to edit human embryos. The decision will allow researchers to genetically modify early embryos and watch them develop for up to seven days, in a bid to figure out what influences miscarriages. The controversial procedure will be carried out at the Francis Crick Institute in London, and will work with up to 30 embryos to begin with, though there are hopes they could extend their research using more.
