https://www.theguardian.com/commentisfree/2017/aug/03/gene-editing-mitochondrial-replacement-therapy-designer-babies >A landmark US study by scientists at Oregon Health and Science University in Portland has for the first time successfully edited out a genetic mutation that could cause heart disease, but the fearmongering over designer babies rages on. Where would research into cures for genetic diseases be without a good old debate around the scary future of eugenics? >For once, let’s not allow that rhetoric to take over the headlines, in the way that it did two years ago, when research into mitochondrial replacement therapy, so-called three-parent babies, made strides. This is a good and promising breakthrough, not something to fear.
