Did you know most 'complete' Streptomyces genomes are missing their telomeres? Thanks to David and Tues hard work, we now have a new tool to recover them! A pleasure to be part of a team. :) 🦠🧪💻 #microsky

I am hiring! - looking for a Staff Scientist to co-run my research group with me. Staff Scientist is a senior professional scientist role at EMBL. Please forward to people you might know who could be interested! embl.wd103.myworkdayjobs.com/en-US/EMBL/j...

Around 10% of your Nanopore reads (SQK-RBK114) are incorrectly trimmed. Here is why, and how our new tool Barbell solves it: www.biorxiv.org/content/10.1... Want to get started? github.com/rickbeeloo/b...

🚀 New in Fasten: fasten_head Unix head, but FASTQ-aware 🧬 ✅ Get first N reads (not just lines!) ✅ Works with paired-end reads ✅ Can limit by bases OR reads ✅ Blazingly fast (it's Rust 🦀) cat huge.fq | fasten_head -r 1000 Stop doing math with -n. Let the tool understand your data.

Bacterial telomeres are common, just not so much in RefSeq 'complete' genomes. But they can be added by the new tool David Faurdal wrote. I am thrilled to see this out as a preprint here: www.biorxiv.org/content/10.1... @tilmweber.bsky.social @thombooth.bsky.social

RIP Jane Goodall, by all accounts a wonderful woman who loved this Far Side cartoon

Delighted to see our paper studying the evolution of plasmids over the last 100 years, now out! Years of work by Adrian Cazares, also Nick Thomson @sangerinstitute.bsky.social - this version much improved over the preprint. Final version should be open access, apols. Thread 1/n

This tool looks incredible, I've been missing something exactly like this to analyze assembly graphs, which is necessary to understand more complex genome structures.

Preprint out for myloasm, our new nanopore / HiFi metagenome assembler! Nanopore's getting accurate, but 1. Can this lead to better metagenome assemblies? 2. How, algorithmically, to leverage them? with co-author Max Marin @mgmarin.bsky.social, supervised by Heng Li @lh3lh3.bsky.social 1 / N

Definitely hard to measure, but here is our best attempt from a new benchmarking paper to be preprinted in the next few weeks. Element appears to be the current king of homopolymers. Illumina does worse than HiFi beyond 20 bp. (This is all measured on human DNA)

New blog post! I added a new feature to @gbouras13.bsky.social's Pypolca: homopolymer-only polishing. Potentially useful for cross-sample polishing - early test on Cryptosporidium looks promising. Check it out here: rrwick.github.io/2025/09/04/h...

Maybe I am being grumpy, but can people please stop using poorly curated databases of antibiotic resistance genes (I am looking at you, DeepARG) on shotgun metagenomic data and then present these results without any reflection on their validity, or shortcomings of databases?

The TaxTriage paper www.biorxiv.org/content/10.1... has a discussion of this that I still need to grok. It's kind of mentioned as an aside in the main text, need to dig!

Just out: metagenomics with internal standards yields phylogenetically resolved genome ("~cell") counts of bacteria, archaea, and photosynthetic eukaryotes per L of seawater, over the AMT29 Atlantic transect, via "single copy" genes (recA, radA, psbO). Compares with microscopy and flow cytometry.

Announcing myloasm, a new long-read (ONT R10/PacBio) metagenome assembler that I've been working on during my postdoc in the Heng Li lab (@lh3lh3.bsky.social). myloasm-docs.github.io

ARTIC 2 is here!

@lh3lh3.bsky.social's latest assembler has really pushed using "routine" ONT libraries (N50s 30KB ish) to get to near T2T assemblies, leveraging read length for (diploid) error correction. Heng continues to be the fountain of excellent sequence bioinformatics tools and it impressive to see.

So glad this is finally out. The method has been instrumental in allowing us to compress the AllTheBacteria data - ~2 million bacterial genomes shrink from 3Terabytes (gzipped) to 100Gb using phylogenetic compression. Great work by @brinda.eu

DTU IT is tracking some network issues that seem to also affect the #antiSMASH servers. I'll post an update once I know more.
