Turns out the order of your scRNA-seq QC pipeline matters more than we thought: removing ambient RNA before doublet detection can reduce doublet detection performance! Our new paper from the amazing PhD student @michellemeier.bsky.social

StrainSpy’s GLMM framework enables straightforward integration of large, multi-cohort microbiome studies. Re-analysis of a large colorectal cancer dataset identified both known and novel strain-level associations, including in E. coli, with an accompanying enrichment of adhesin-encoding genes.

Exciting collaboration with @annabiosys.bsky.social's lab just went online. @isbscience.org metaSPLiT: a fast, efficient, and relatively low-cost method for single-cell transcriptomics in the human gut microbiome. 👇

👀👇 New work on sexually transmitting Shigella (press-friendly: bit.ly/4bBarEL) From continued collaboration with @clairejenkins2.bsky.social @ukhsa.bsky.social, @pducambridge.bsky.social co-lead @hsalje.bsky.social, a talented student Julia Marshall www.linkedin.com/in/julia--ma..., and others! 🧫🧬💊

Using MxSure, we estimated within-host substitution rates and transmission SNP thresholds for multiple commensal bacterial species, including Bifidobacterium longum and Bifidobacterium bifidum.

In addition to accurately identifying strain replacement events in S. pneumoniae, we show that phylogenetically informed thresholds outperform methods that do not model the underlying evolutionary process, such as Youden's J statistic, which is often used in metagenomic transmission studies.

ggCallaroo v0.1.0 is now out! This snakemake pipeline predicts, clusters and annotates bacterial genes using ggCaller, Panaroo and Bakta. It generates Panaroo files with functional annotations already integrated, which can then be used with the usual downstream tools. github.com/samhorsfield...

@wytamma.bsky.social 's WASM tools have transformed my experience of teaching Python to first year undergraduate biologists this year. Since last year, I've been teaching ~400 undergrads how to code (functions, lists, dictionaries, loops) over (one hour intro lecture +) two 2-hour practicals. 1/n

Great talk from Michael Payne at #ABACBS2025 on DAMPA - tool for designing probe panels for targeted metagenomics using pangenome graphs! Captures all diversity efficiently, uses fewer probes than competitors. Critical for syndromic surveillance! 🧬🔬 #Metagenomics

Happy to see that Spacedust is now published on Nature Methods! It combines sensitive Foldseek structure search and conserved neighborhood detection to discover functionally-associated gene clusters in prokaryotic & viral genomes. 1/6🧵

Sometimes you meet absolutely incredible bioinfo-magicians. It was a huge privilege when @shenwei356.bsky.social joined our group for a year on an @embl.org sabbatical. While here, he developed a new way of aligning to millions of bacteria, called LexicMap 1/n www.nature.com/articles/s41...

Large AI models are reported to achieve high accuracy (AUROC) predicting pathogenic variants across the genome. A preprint reports that the predictions are based on splice variants. Using only this info (no sequences, no AI) achieves AUROC=0.944 across noncoding variants. 1/2
