Medical Ethics Issue

AP is reporting:

Britain has granted permission to scientists to create a human embryo with genetic material from two mothers, officials said.

Scientists from Britain's Newcastle University plan to transfer the pro-nuclei - the components of a nucleus of a human embryo - by a man and woman into an unfertilized egg from another woman to prevent mothers passing certain genetic diseases to their unborn babies.

Wow! I've got no clue whether this is a cause to celebrate (women with genetic diseases can now have healthy children!) or mourn (we've reached a new level of tinkering with humanity). I think it's more a cause to think and hope that someone intelligent will present an articulate opinion that is not just a knee-jerk reaction.
