(Another by Nicole Gaudelli's team apparently coming soon.)
Why care:
Base editors can install predictable gene edits without DNA breaks. The described C-to-T editors are as efficient at current tools, but create less off-target damage in the genome and are smaller, which helps with delivery in vivo.
