AI Summary

Cornell University researchers have refined a CRISPR‑based technique for use in fruit flies, creating a safer, more precise method to probe gene function in living tissues. Their approach swaps the conventional double‑strand DNA cuts for gentler single‑strand “nicks,” reducing damage while still allowing functional analysis. The findings were detailed in the Proceedings of the National Academy of Sciences, highlighting the potential to better study gene roles in development and disease.
