The number of infertile couples seeking help abroad has tripled since lawmakers in Roman Catholic Italy crossed party lines last year to approve one of Europe's most restrictive laws on assisted reproduction. This weekend the standoff will come to a head with a four-part referendum that, if passed, would significantly change the law. The poll has shattered traditional political alliances and elicited emotional appeals from church pulpits. Picture taken June 6, 2005.

据 Digital Trends 和 MIT Technology Review 报导,上週一群波特兰的科学家用基因编辑技术 CRISPR 实现美国首次成功尝试基因改造的人类胚胎。先前曾公诸于世,类似的改造人类胚胎测试都有 3 次,都发生在中国。
这次的实验特别之处在于,实验胚胎的数目更多,而且有望透过 DNA 编辑修补基因缺陷,预防先天性疾病。由奥勒冈健康与科学大学的 Shoukhrat Mitalipov 所领导,进行了多个单细胞胚胎的 DNA 编辑。
