Crispr technology is sort of like a pair of tiny and precise scissors for the molecular world. This gene-editing tool can snip out sections of DNA and replace them with new, healthy genetic stretches. Scientists and doctors have high hopes for its health implications, and they’ve used it to alter severe genetic defects in single-celled embryos. Here, Live Science brings you news and features surrounding Crispr achievements and challenges.
