We already have genetically modified fruits and vegetables. Many that are overtaking natural species, and many that are designed to die off and not self propagate. We read that cloned meat, from cloned animals who have higher rates of disease and mutations, is in the US food system. Mmm, serve up that steak.
Where is it all leading to?
British authorities on Thursday approved scientists' use of animal eggs to create human stem cells, a ruling that will boost the supply of stem cells for research.
The decision means that researchers will be able to refine their techniques for producing human stem cells by practicing first on animal eggs, of which there is a steady supply. Similar work involving human-animal stem cells is also under way in China and the United States.
"This is good news for research, but most importantly, it is good news for patients," said Sophie Petit-Zeman of the Association of Medical Research Charities.
Scientists have been exploring the use of stem cells to cure many degenerative diseases such as Parkinson's, since the cells have the ability to develop into any cell in the human body.
The Human Fertilization and Embryology Authority said it had granted conditional one-year licenses to two institutions to conduct research using mixed human-animal embryos. In Britain, all research involving human eggs and embryos must be approved by the authority.
Scientists from King's College and Newcastle University submitted applications last year to create human stem cells using animal eggs.
