Scientists edited DNA in human embryos; the breakthrough is real, but so are the risks - Ynetnews

## Columbia researchers used base editing, a CRISPR-related method designed to alter single DNA letters with less damage, in embryos never intended for pregnancy; the work revives questions over disease prevention, inherited genetic change and ‘designer babies’. A team led by developmental biologist Dieter Egli reported that it carried out precise genetic editing in human embryos at the earliest stages of development, using embryos that were not intended for implantation or pregnancy. The resear
