The first hybrid embryos in Europe - a blend of human and cow DNA - have been created by scientists in Newcastle.
The milestone, which is political rather than scientific, will trigger a furore, since the advance comes a month before MPs are to debate the future of such research, which has been condemned by the Catholic Church as "monstrous".
A British Council meeting in Israel was told by Dr Armstrong that the hybrids were created by injecting DNA derived from human embryo cells into eggs taken from cows ovaries which have had DNA responsible for their characteristics removed, so called nuclear DNA, and leaving only cow DNA used to power the cells.
