# Research Daily Summary: What Happened on October 20, 2026

**ALTER edits RNA more efficiently than two Cas13 tools in cells**

The editor uses engineered human Argonaute 2 and showed similar or lower off-target editing in comparisons with CURE and RESCUE.

## Today in brief

In HEK293T cells, the RNA editor ALTER produced 1.9 times the average C-to-U editing of the Cas13 editors CURE and RESCUE, with similar or lower off-target editing. [1]

## The day in numbers

- **1.9-fold**: ALTER’s average C-to-U editing of mRNA targets compared with CURE and RESCUE in HEK293T cells. [1]
