Last week we released dplyr 1.2.0, but we left off something VERY important 🙂 `dplyr::if_else()` and `dplyr::case_when()` are now up to 30x faster and use 10x less memory! We dive into how we achieved these numbers in this new #rstats post! tidyverse.org/blog/2026/02...

@mikelove.bsky.social : There was PyDESeq2, and now there is rust_deseq2! crates.io/crates/rust_...

I started offering career advice to two junior colleagues today in separate meetings, and both times I caught myself thinking that, if I'm honest, I don't have very good advice on navigating the current funding and job climate. I think it's important to say that no one does.

We're donating PyDESeq2 to @scverse.bsky.social for long-term maintenance & development. Python reimplementation of DESeq2, ecosystem member since 2023, now in the hands of one of the best open source communities in omics. Good science requires good open source. github.com/scverse/PyDE...

AlphaGenome is out in @nature.com today along with model weights! 🧬 📄 Paper: www.nature.com/articles/s41... 💻 Weights: github.com/google-deepm... Getting here wasn’t a straight path. We discussed the story behind the model, paper & API in the following roundtable: youtu.be/V8lhUqKqzUc

Excited to share our latest work in @ajhgnews.bsky.social 🧬📄 We mapped the regulatory landscape of human liver at single-nucleus resolution using snMultiome, connecting genetic variants to the cell-type mechanisms underlying cardiometabolic disease. www.sciencedirect.com/science/arti...

It is a PROBLEM that the new MANDATORY ScienCV platform does not (as far as I can tell) enable one to indicate co-first or co-senior authorship in your bibliography. This is a massive disincentive to collaborative science and it needs to be fixed.

This is the most elite change in #Positron, it's so calming. #rstats #python #databs

Our paper on the Expanded Registry of candidate cis-Regulatory Elements (cCREs) is out 🎉 www.nature.com/articles/s41... To celebrate, here’s a "meme-torial" walkthrough of the science. Let’s get started 🧵 1/11

We used a similar design in this paper: www.sciencedirect.com/science/arti... Found that in cis-MR with multiple colocalising instruments (i.e. multiple indepdent signals colocalise between eQTL and pQTL traits) sign concordance was around 95%:

Clever use of proteomic data to stress-test TWAS and QTL colocalization methods, revealing a high false sign rate. This hypothesis about high-LD and cross-tissue confounding is particularly interesting:

If you like larger sample sizes, then do check out our reprocessed and fine mapped cis-eQTLs and cis-sQTLs (leafCutter and MAJIQ!) from the INTERVAL cohort (whole blood, n up to 4,729)! zenodo.org/records/1795... These will be on the eQTL Catalogue FTP soon as well. cc @yosephbarash.bsky.social

It would be interesting to revisit these specific analyses with eQTL sample sizes in 1000s like in @mikelove.bsky.social 's recent work. IMO it's very plausible that while typical cis-eQTL sample sizes find lots of eQTLs, the relevant ones with enough power for colocalization need a bigger N.

We used a similar design in this paper together with @mikelove.bsky.social: doi.org/10.1016/j.xh... Found that in cis-MR with multiple colocalising instruments (i.e. multiple indepdent signals that colocalise between matched eQTL and pQTL genes) sign concordance was around 95%:

Reproducibility is key to science. In computational biology, we routinely manipulate high-dimensional data (spatial, single-cell, bulk) through filtering, normalisation and transformation. Capturing those steps clearly improves reproducibility and transparency. tidyomics.github.io/tidyomicsBlo...

Happy to share our new preprint from @sashagusevposts.bsky.social and @nmancuso.bsky.social labs! We introduce Mr. PEG, a framework integrating perturbational screens, eQTL, and GWAS data to identify mediating genes for complex traits. (1/n) www.medrxiv.org/content/10.6...

GWAS has been an incredible discovery tool for human genetics: it regularly identifies *causal* links from 1000s of SNPs to any given trait. But mechanistic interpretation is usually difficult. Our latest work on causal models for this is out yesterday: www.nature.com/articles/s41... A short🧵:

Happy to share our new method F-MoDA to find motifs in genomic attribution maps just published in MLCB 2025 proceedings! F-MoDA has improved specificity, sensitivity, accuracy, conciseness, and runtime compared to TF-MoDISco. Led by Ofir Yaish: proceedings.mlr.press/v311/yaish25...

While we've been somewhat successful in spurring adoption of alevin-fry/simpleaf for scRNAseq processing, an impediment Dongze brought to our attention (now working directly w/ many experimentalists) was the need for a nice QC report for it's output; hence QCatch www.biorxiv.org/content/10.1... 1/x

Do transcriptional activators work on any promoter? Our data says no. 🙅‍♂️ Despite driving ~2/3 of mammalian genes, CpG island (CGI) promoters have remained a puzzle. We identified >50 activators that are exclusively compatible with this promoter class. 🧬

…and we don’t have this matrix at good completeness & precision, despite many efforts (including our own 👇). Hopefully we will in not too distant future, but given the difficulty of this task, I’m not holding my breath regarding virtual cells. pubmed.ncbi.nlm.nih.gov/41173850/

I've been thinking about the "virtual cell" concept and wanted to write up a few thoughts. Specifically on how I think the prior experience in GWAS informs the most likely way these models will be useful. andrewcarroll.github.io/2025/12/23/t...

Little over a month left to submit an abstract to #EuroBioC2026 (eurobioc2026.bioconductor.org/pages/submis...), which will be held in Turku, Finland. Here are a couple of Finnish Christmas traditions that you might not know:

Our new preprint is out: www.biorxiv.org/content/10.6... We show that GRN benchmarks commonly used can overestimate performance due to negative-sampling choices, sometimes allowing simple degree-based baselines to rival more complex GNNs. A reminder of why bias-aware evaluation matters!

Biologists who teach: in what order do you teach the four forces of evolution? Genetic drift first or selection first? And I'm still struggling to smoothly fit in HWE so that its utility is emphasized (students focus so much on how likely it is that assumptions are violated). #iteachbio 🧪 #Evolution

I have seen many people say that no academic needs to use LLMs for writing, because of course we are all already excellent at writing. I fear that risks exacerbating imposter syndrome in early career researchers. I therefore want to raise my hand and say while I enjoy writing, I find it hard.
