Ore­gon sci­en­tists do first hu­man gene em­bryo edit­ing in U.S.

The Hamilton Spectator - - HEALTH -

For the first time in the United States, sci­en­tists have edited the genes of hu­man em­bryos, a con­tro­ver­sial step to­ward some­day help­ing ba­bies avoid in­her­ited dis­eases. Ac­cord­ing to MIT Tech­nol­ogy Re­view, the ex­per­i­ment was just an ex­er­cise in sci­ence — the em­bryos were not al­lowed to de­velop for more than a few days and were never in­tended to be im­planted into a womb. The pub­li­ca­tion re­ported the news on Wed­nes­day. Of­fi­cials at Ore­gon Health & Sci­ence Univer­sity con­firmed that the work took place there and said re­sults would be pub­lished in a jour­nal soon. The sci­en­tists re­port­edly used a tech­nique called CRISPR, which al­lows sec­tions of DNA to be al­tered or re­placed. The only pre­vi­ous work like this has been re­ported in China.
