Original source: Safe and ethically uncontroversial stem-cell treatments for a host of diseases came closer to reality on Sunday thanks to a major breakthrough by British and Canadian scientists.

The research raises the practical prospect for the first time of developing wide-ranging ‘spare part’ stem-cell treatments without having to destroy human embryos.
