Summary

Researchers at Cornell University have developed a safer and more precise way to study how genes function in living tissues by refining a recently developed CRISPR-based genetic technique in fruit flies, enabling researchers to better study how genes contribute to development and disease. Published in the Proceedings of the National Academy of Sciences , the work highlights a new method that replaces the harsh DNA cuts used in traditional CRISPR analysis with gentler cuts known as "nicks."
