The subject article1 discussed in this News & Views has, since publication, been updated to correctly identify the nuclease used in the study, with a change from Transposon-associated transposase B (TnpB) to Cas12f1 from the Candidatus Woesearchaeota archaeon (CWCas12f1). Discussion of base editing in this article has now been updated from TnpB to refer to Cas12f1 in the HTML and PDF versions of the article.
