Heathy donor DNA can fix genetic problems in the approved fertility procedure.
On Tuesday February 3, the UK House of Commons voted in favor of legalizing nuclear transfer so that a small number of women with a particular subset of mitochondrial disease could try to have unaffected and genetically related children.
There are large social and ethical considerations that mitochondrial replacement forces us to confront. Most importantly, this technology raises one of the thorniest questions humanity will ever face: are we willing to genetically modify future generations of humans?
What if you could trace your ancestry back to around 5,000 years ago? Researchers were able to do just that in a fascinating new DNA study, which found a direct genetic link between the ancient remains of Native Americans and their living relatives.
