Eight Healthy Babies Born Using DNA from Three People

Researchers in Britain have reported the birth of eight healthy babies using a groundbreaking technique involving DNA from three individuals. The method, which is approved in the UK and Australia but not the US, avoids passing on devastating mitochondrial diseases from mother to child. Scientists transfer the mother's nuclear DNA into a donor egg with healthy mitochondria, effectively circumventing the harmful mutations. While one baby showed slightly higher-than-expected levels of abnormal mitochondria, it's not considered disease-causing. This represents a significant advancement for families affected by mitochondrial diseases.
