I saw a Youtube video by @omgenomics.com profiling the work that @plasmidsaurus.bsky.social has been doing in streamlining sample preparation for their Plasmid sequencing and RNA-seq products.
Interesting to see @OpenTrons instruments *everywhere*, and how they turn operations "pipette triggers".
We just released a video from our visit to @plasmidsaurus.bsky.social, where we spoke with Mark Budde and team: www.youtube.com/watch?v=nS2o...
Highlights include:
β
3D printed magnetic bead contraptions
β
When sequencing more is easier than sequencing less
β
Bread machine analogies
Playing with sandbox.bio. This was remarkably cathartic.
That tech oligarchs are noisy and incensed about the remote possibility of a wealth tax and utterly silent about the murder of a man who was only using the phone they invented to chronicle the thuggish government goon squads should tell you everything about these desiccated souls.
π Our new paper on Alignoth just published in Bioinformatics!
Alignoth generates self-contained interactive HTML read alignment plots from BAM files β Rust-based, portable, and ideal for headless workflows.

Blogpost: I took an oral probiotic for a month and did microbiome sequencing at @Plasmidsaurus.

Releasing alignism, a small tool that I have found useful for doing multiple sequence alignment in browser.

- The hard work was done by the awesome biowasm team!
- Does tree building too
- V fast compared to e.g., muscle on EBI
- Not tested that much!
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.

You can also use 42basepairs to view public buckets and preview file contents e.g. 42basepairs.com/browse/s3/op... π
One last bioinformatics puzzle before the holidays: Can you figure out the file formats of unlabeled sequence data? π

These are fun educational puzzles to improve debugging skills of students! thanks to @robert.bio for creating these
sandbox.bio/puzzles
We are thrilled to announce the first official release (v0.1.8) of #π―π²π±π±π²πΏ, the successor to one of our flagship tool, #π―π²π±ππΌπΌπΉπ! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen.
1/n
I'm building out a new section on sandbox.bio with debugging puzzles that could be relevant: sandbox.bio/puzzles
I didnβt realize yβall got Rust tools compiled in a biowasm compatible way, thatβs awesome!
Workshop landing page with demos here -> wasmodic.github.io
Hmmm π§
@wytamma.bsky.social : so, it took a little bit of extra time (not the flight back from the CZI meeting), but I decided to just f#&$ing do it, and the basic code to build and parse with the auxiliary fastq index is working (github.com/COMBINE-lab/...). 1/2
Excited to announce a new bqtools tutorial on sandbox.bio by @noamteyssier.bsky.social! Learn about the BINSEQ file format, and how it can replace FASTQ files for better data compression and faster parallel processing: sandbox.bio/tutorials/bq...
BINSEQ is a high-performance format for sequencing data and bqtools is a CLI tool that lets you create and manipulate these files in the style of samtools.
Excited to release a tutorial with @robert.bio showcasing how to use it to encode, decode, and grep sequences in the browser on sandbox.bio!
Interested in learning materials to prepare undergraduate students for working with pathogens and pathogen data? Iβm hosting a small curriculum development sprint/workshop. Industry/clinical and educators needed.
Please share. Apply by November 28, 2025

Students often ask me how to get bioinformatics experience, and I say "projects, projects, projects!". And inevitably they say "okay but how do I find a project to do?". So I made this video with 15 project ideas:

Illustration of Burrows-Wheeler Transform and many auxiliary structures from the input string how$now$brown$cow$#
New tool "bwt-svg" for making illustrations of the BWT and the many auxiliary arrays and other structures related to it. Pyodide-based no-installation-necessary interface here: benlangmead.github.io/bwt-svg/. (H/t to @robert.bio for pointing me to pyodide!) Full repo: github.com/benlangmead/....
Ah, by sorting the matrix, I meant sorting the set of 9 strings defined by each row of the matrix, not sorting the 2 strings defined by each column of the matrix.
Oh wow, BWT in a Google Sheet, thatβs awesome!
This is wonderful to play with, highly recommended for anyone who wants to understand the BWT
Just published an interactive article about a magical algorithm known as the Burrows-Wheeler Transform, which powers sequence alignment tools like bowtie and bwa: sandbox.bio/concepts/bwt
It's also notoriously unintuitive so I'm hoping this article helps you build that intuition.
Screenshot of the sandbox.bio playground for running a linux environment in the browser
"Pro tip": If you are in a restricted environment & need quick access to a linux terminal running locally in the browser for some #bioinformatics messing around - check the sandbox.bio terminal playground. Made a bitly link for for convenience: bit.ly/bioterminal
Interesting! Have you written about this somewhere?
I still need to get around to reading the binseq paper, but I imagine a sandbox.bio tutorial might help spread the word? @noamteyssier.bsky.social let me know if youβd be interested
