I'm a former Community Notes super-user interviewed for this piece. Whether the notes are written by people or language-mimicking algorithms, the central flaw of Twitter's Community Notes is the same as it's always been: it's a "fact-checking" system that doesn't involve the checking of facts.

Super excited to see this out! Fantastic collaboration with Luke O'Connor and trainees Amber Shen and Xinran Wang. Thread with details will come soon, but linear ARG provide a HIGHLY efficient representation of genotype data that can be treated as a linear operator www.biorxiv.org/content/10.6...

If you use dim. reduction, you may be interested in two recent preprints we've posted on contrastive PCA: The Rayleigh Quotient and Contrastive Principal Component Analysis I & II w/ Maria Carilli & Kayla Jackson. They cover a lot of ground from theory to practice. 1/🧵

Latest from Shendure & Qiu labs (@cxqiu.bsky.social) )! We combined a new 4M cell mouse whole embryo scATAC-seq atlas (E10-P0), millions of 'evolutionarily coherent' orthologs from 241 mammalian genomes (Zoonomia), and the CREsted CNN framework (@steinaerts.bsky.social).

Friendly reminder that ordinal values admit an ordering, but no notion of distance. Without a notion of distance even the concept of linear models is ill-defined. Please do not use ordinary least squares to analyze ordinal data. For gratuitous discussion see betanalpha.github.io/assets/chapt....

You know what's better than inflating the variation of your observational model to heuristically accommodate "outliers"? Actually modeling the contaminating data generating process.

Ambient RNA & barcode swapping is a serious issue in single-cell genomics. Tools such as CellBender, scAR, DecontX & SoupX. We have developed CellSweep which is faster (in some cases by a lot) and much more accurate. Extensively tested and benchmarked. www.biorxiv.org/content/10.6... 1/

The empty drops you threw out in your single-cell RNA sequencing analysis might be hiding mysterious things 👀 check out our bioRxiv preprint! The empty drops do not contain cells. Yet we can still use them to learn interesting things about biology and technology. 1/

Excited to share this preprint that describes my latest work on using GPUs to accelerate processing of RNA-seq data. The title says it all: "RNA-seq analysis in seconds using GPUs" now on biorxiv www.biorxiv.org/content/10.6... and github github.com/pachterlab/k... Figure 1 shows they key result

How many samples should you sequence? Collect too few, and the experiment is inconclusive. Collect too many, and the costs add up very quickly. Check out our bioRxiv preprint and calculator at poweranalysis-fb.streamlit.app! 1/

After years of work, the centerpiece of my PhD is published in @natmethods.nature.com! Read it to learn about the biophysical insights we can get from single-cell data! But first, I would like to talk a bit about RNA velocity and normalization. 1/
