Three-person IVF moves closer in UK

The UK has moved closer to becoming the first country to allow the creation of babies from three people.
The Human Fertilisation and Embryology Authority (HFEA) has advised the government that there is no evidence that the advanced form of IVF is unsafe.
The fertility regulator's public consultation also showed "general support" for the idea as the benefits outweighed the risks.
A final decision on whether to press ahead rests with ministers.
