This Week in Nature

In Nature Biotechnology this week, a team led by Massachusetts Institute of Technology researchers report on the use of a gene-editing approach called CRISPR to correct a disease mutation and phenotype in mice, furthering the therapeutic potential of the technology. In the study, the scientists were able to deliver into the animals the Cas9 nuclease, along with a snippet of RNA that directed the enzyme to a specific portion of DNA where it causes double-strand breaks.
