An anti-CRISPR for gene editing

Researchers have discovered a way to program cells to inhibit CRISPR-Cas9 activity. "Anti-CRISPR" proteins had previously been isolated from viruses that infect bacteria, but now University of Toronto and University of Massachusetts ...

Reading the rules of gene regulation with CRISPR

We have barely begun to crack open the rulebook for the vast noncoding regions of the genome. Two new methods, building on CRISPR advances, may help reveal some of the pages.

Using light to control genome editing

The genome-editing system known as CRISPR allows scientists to delete or replace any target gene in a living cell. MIT researchers have now added an extra layer of control over when and where this gene editing occurs, by ...

Scientists develop new techniques to track how cells develop

Understanding how various cell types differentiate themselves during development is one of the fundamental questions in developmental biology. Using genome-editing tools, Harvard scientists are getting closer to finding answers.

How the butterfly got its spots

By tweaking just one or two genes, Cornell University researchers have altered the patterns on a butterfly's wings. It's not just a new art form, but a major clue to understanding how the butterflies have evolved, and perhaps ...

Human cloning with Chinese characteristics

Chinese genetic scientists must not be put off sensitive research by ethical concerns, the team behind a controversial study on modified human embryos said Wednesday as debate erupted over the paper.
