Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp.... genzplyr is dplyr, but bussin fr fr no cap.

Studying cancer evolution needs multi-region or single cell seq for phylogenetics, right? Amazingly (I think!) we found single-sample bulk methylation suffices, via analysis of "fluctuating methylation". In @nature.com today led by brilliant @calumgabbutt.bsky.social www.nature.com/articles/s41...

Clonal tracing with somatic epimutations reveals dynamics of blood ageing - Nature
The discovery that DNA methylation of different CpG sites can serve as digital barcodes of clonal identity led to the development of EPI-Clone, an algorithm that enables single-cell lineage tracing through cellular differentiation at scale.

🚀 Our Nature paper on EPI-Clone is live I loved analyzing the human data - we discovered that after age 50, blood production shifts to an oligoclonal pattern, and these expansions aren’t driven by CH mutations! Dive into @larsplus.bsky.social thread for the full story & visuals.
