"UK scientists have applied for permission to create embryos by fusing human DNA with cow eggs.
Researchers from Newcastle University and Kings College, London, have asked the Human Fertilisation and Embryology Authority for a three-year licence.
The hybrid human-bovine embryos would be used for stem cell research and would not be allowed to develop for more than a few days.
But critics say it is unethical and potentially dangerous.
Stem cell research is one of the most promising areas of medical science.
They are the body's master cells and five-day-old embryos are packed with them - each with the potential to turn into any tissue in the body.
It is this ability which scientists want to harness to treat diseases such as Parkinson's Disease, strokes and Alzheimer's Disease.
To do that, they need to have access to thousands of embryos for research."
The result will be, technically speaking, a chimera. The ancient Greeks were probably wiser in this regard. They considered a chimera to be a monster.
Indeed, something seems very monstrous about this idea.
"Thus saith the LORD, thy redeemer, and he that formed thee from the womb, I am the LORD that maketh all things; that stretcheth forth the heavens alone; that spreadeth abroad the earth by myself." Isa 44:24.
