3人の親を持つ子供を生む技術がアメリカでも承認されたらしい


2015年2月の時点でイギリスではすでに承認されていた3人の子供を産む技術。この技術がアメリカでも承認されたらしい。
このニュースを聞いてふと思い出したのは、きらきらひかるという小説の中のワンシーンでした。

”きらきらひかる”は江國香織によって1994年に書かれた、アルコール依存症の笑子と同性愛者の夫と夫の恋人の三角関係を描いた小説。
そんなあやうい関係がうまくいくはずもなく、思いつめた笑子が産婦人科医に『夫と夫の恋人と自分の三人の子供は作れませんか?』と質問するシーンが(たぶん)あった。

その時は『なんて突拍子もないことを言うかわいそうな人なんだろう』的なニュアンスでそのセリフが解釈されていたけど、現実に3人の親を持つ子供を作れる時代が来てしまったのだなあと・・・。20年ちょっとで世界はがらっと変わってしまうんですね。

まあでもこの技術はこういった三角関係のために使われるのではなく、まれ(5000人に一人くらい)に起こるミトコンドリア異常を持った状況を回避するために使われるとのこと。




 

ミトコンドリア病の女性の卵子から核を取り出し、健康な別の女性の卵子核と交換するらしい。
健康な子どもが一人でも多く生まれる技術ができたことはすごく喜ばしいことだと思うけど、技術があることで、新しいニーズも生まれてくるだろうから、これから難しい時代になっていくんだろうなと思う。それこそ笑子のような人がでてくるかもしれない。

イギリスとアメリカで承認された技術は日本で承認されるのか、それは何年後になるのかなあ。

I adore the comforter, lovely bltcuckrranay smell, i have the solid perfume of it. I'm not keen on the idea of the solid shampoos not really sure why though.

Microsoft has plans, especially in the realm of games, but I’m not sure I’d want to bet on the future if this aspect is important to you. The iPod is a much better choice in that case.

      1. *grumble mumble*On a related note as soon as I saw Samara I had my first “pulled out of un2vrese&#8i21; experience. Her outfit doesn’t look like it fits the ME universe, especially given her personality. She looked like she had escaped from the Marvel or DC universe. Previously I’d always considered ME to be like playing in Babylon 5 O_o It just doesn’t fit.I don’t even want an explanation really as it’s become clear that whenever the ME devs are asked about things like this they come up with some BS rather then just admit to throwing in fan-service.(I still love the games to pieces though)

    1. Even at the official SEGA forums, things are getting mixed up in regards to the recent layoffs. Hopefully we will hear some news from people like Kate, and maybe they were hired in another career. Rerruucttsing is a risky task, and its a shame we lost some of our friends.
