Genetic diagnosis says that the embryo stage is now possible. embryo胚胎(对人来说，一般指三个月以内的胚胎) Hope: embryo stage (possible) Hope walks hand in hand with spectra of designer babies; breakthrough work combining in vitro fertilization with genetic selection, could soon take things a step further by creating a healthy baby whose bone marrow will save the lives of a dying sister. What could be wrong with that? spectra (单 spectrum)光谱；波谱 Technological breakthrough: Spectra of designed babies: + fertilization “The problem is that the technology is way more in advance than legal understanding. The technology and sciences change almost daily. It’s as if the law were running at full speed to catch up.” Technology law It all began with Louis Brown, the world’s first test tube baby born in 1978. Human life can be created outside the womb and thousands of previously infertile couples were able to have children. womb 子宫 infertile不结果实的，不生育的 But there was another side of that coin.
