Should scientists be allowed to modify human embryos?

The body which regulates fertility research is to consider the first application in the UK to genetically modify human embryos.

The Human Fertilisation and Embryology Authority (HFEA) will consider an application from Dr Kathy Niakan to edit human genes for research into miscarriages.

Dr Niakan said the experiments would provide a deeper understanding of the earliest moments of human life and could reduce miscarriages.
