Popular Science - - BEST OF WHAT’S NEW 2017 -

CRISPR, the DNAedit­ing tool, took a deep cut into dis­ease rem­edy this sum­mer. Ore­gon Health and Sci­ence Univer­sity re­searchers be­came the first in the U.S. to at­tempt to tweak hu­man em­bryos’ DNA to fix a ge­netic dis­ease (a mu­ta­tion that causes hy­per­trophic car­diomy­opa­thy, a type of heart con­di­tion). It’s a mile­stone, but more re­search is needed be­fore the edited hu­man eggs can grow into ba­bies.
