Humans and Animals Being Hybridized
Regulators in the UK have given scientists the green light to create human-animal embryos for research.
The Human Fertilisation and Embryology Authority granted permission after a consultation showed the public were "at ease" with the idea.
Experts said it was vital for research into life-threatening diseases.
Two centres, King's College London and Newcastle University, will now be able to begin their work under one-year research licences.
Any other centres wishing to do similar work will have to apply to the HFEA for permission, which will make a decision on a case-b-case basis
