Thanks to @AnnaArco on Twitter for the link to this BBC article on embryo testing: Universal embryo test 'very near'. It is an extroardinary example of skirting round the essential point. The test will be able to discover any of 15,000 genetic defects. There are worries about it being used to discover "less serious" conditions and thus result in "designer babies".
But the whole point of any of these tests is to arrange for the abortion of babies that have "abnormalities". You can call them "abnormalities" when it is a case of an unborn child - it seems that there is no need to scruple about language for children who can be killed to order.
