2 scientists win Nobel chemistry prize for gene-editing tool

Two scientists won the Nobel Prize in chemistry Wednesday for developing a way of editing genes likened to "molecular scissors" that offer the promise of one day curing inherited diseases.

Working on opposite sides of the Atlantic, Frenchwoman Emmanuelle Charpentier and American Jennifer A. Doudna came up with a method known as CRISPR-cas9 that can be used to change the DNA of animals, plants and microorganisms. It was the first time two women have won the chemistry Nobel together—adding to the small number of female laureates in the sciences, where women have long received less recognition for their work than men.
