The Food and Drug Administration (FDA) has demanded a fertility doctor halt all marketing on an unapproved IVF experiment that creates a human embryo by combining DNA from three separate people.
Scientists have, for the first time, successfully freed embryos of a piece of faulty DNA that causes deadly heart disease to run in families.
Researchers at The Scripps Research Institute (TSRI) claim to have created the first stable semisynthetic organism with extra bases added to its genetic code. The single-celled organism is also able to continually replicate the synthetic base pair as it divides, which could mean that future synthetic organisms may be able to carry extra genetic information in their DNA sequences indefinitely.
