'Human-animal' embryo green light

Regulators have agreed in principle to allow human-animal embryos to be created and used for research.
But scientists wanting to use hybrids will still need to make individual applications, the Human Fertilisation and Embryology Authority said.

An HFEA consultation showed the public were "at ease" with the idea when told it could pave the way for therapies for conditions such as Alzheimer's disease.

Opponents have said many people would be "horrified" by such a move.

I don't see the issue, as long as the space is kept very clean and no possible contamination can escape. But we mess with viruses and the like all the time... same thing.
If it can save lives and end suffering, do it.
