Minibwa is a hybrid of bwa-mem and minimap2 and the successor of bwa-mem for short-read mapping. ~4X/2.5X as fast as bwa-mem/bwa-mem2 for WGS reads at comparable accuracy. Native support of directional bisulfite-seq. Applicable to long reads. Preprint at arxiv.org/abs/2606.15357

Modern DRAM is based on a brilliant design from IBM. But, we're still paying for a latency penalty that's existed since the 60s! In this video, I'm introducing my research project (Tailslayer) that immensely reduces p99.99 latency on traditional RAM!

Can't wait to release a 10-year-old birthday version for SeqKit! - 10 years - 2 papers, 3500 citations - 20 contributors - 40 subcommands - 880 commits - 500 issues - 685.5K Bioconda total downloads Thank you all, dear contributors and users! I'll keep maintaining it. github.com/shenwei356/s...

For those of us interested in software development, data structure design etc in science, this is a must-read. A taste of what is happening in communities letting AI agents go wild writing code, creating PRs, writing documentation : spoiler - humans get addicted, lose perspective, slop everywhere.

Weekend thoughts on Gas Town, Beads, slop AI browsers, and AI-generated PRs flooding overwhelmed maintainers. I don't think we're ready for our new powers we're wielding. lucumr.pocoo.org/2026/1/18/ag...

Most exciting study have seen for ages, and Fernando the most excited speaker. Much anticipated. Highly recommended, a lot of food for thought (and quite a dense paper - lots to think about)

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/ www.science.org/doi/10.1126/...

Cool paper new paper from Lorién López-Villellas, @santiagomarco.bsky.social and others! Super cute and simple idea: In Gotoh's affine-cost alignment, only the M matrix is needed during tracing: we can just search for a gap-length x such that M[i][j] = M[i-x][j]+o+x*e or M[i][j] = M[i][j-x]+o+x*e.

I also have serious concerns about the consolidation of roles (one person is now publisher, chief editor, and also a frequent author) as exemplified in a recent paper that was fast-tracked for publication.

Really exciting that the preprint on Barbell, a new demultiplexer, is finally out! It's the first tool that builds on Sassy, the approximate-DNA-searching tool that @rickbitloo.bsky.social and myself developed earlier this year, specifically with this application in mind.

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...
