Today, March 31st, is International Trans Day of Visibility. In an era of immense difficulty for the community, it can be hard to remember that Trans Day of Visibility is as much about positivity as it is about awareness and resistance.

Ever receive a BAM aligned to “GRCh38” and realize that could mean several different references? We just released ref-solver, a tool that identifies the reference genome behind BAM/CRAM/FASTA files by comparing sequence dictionaries to known builds. 🔗 whatsmygenome.fulcrumgenomics.com Read more 👇

it has been [0] days since I've tried to emulate 64-bit atomic operations using 32-bit atomic ops in a system with relaxed memory ordering

Our latest vg release introduces GBZ v2 with better compression for sequences. I originally assumed that the total sequence length in a pangenome graph would be similar to the size of the genome. This does not hold in the full HPRC graphs due to unaligned centromeres.

Looking for a postdoc to build my new lab at TGen (Phoenix, AZ) focused on pangenome methods for cancer and complex disease. Full stack — from pangenome assembly and compression to association studies and somatic variant discovery. Reach out if interested! guarracinolab.github.io#join

This was such a fun project. Adam's thread on it is a great summary!

Excellent piece about why race is not a biological category and how medical education needs to respond. www.bmj.com/content/392/...

Apply ASAP to be a "Genomics Senior Systems Architect" AKA Linux Herder at @ucscgenomics.bsky.social ! The first test is convincing www.ucsc.edu/careers/ to show you #job number 82880.

Are #redhat #quay.io Docker container builds down for anyone else? Mine are failing with no logs, and then my trigger gets "automatically disabled due to successive internal errors".

You find yourself in the middle of a fastq file. You see + and @ all over the place. How do you find the start of the current record?

Did anybody ever actually write up the "Heng Effect" (where adding variants to your pangenome graph can *reduce* its usefulness for samples unlikely to contain those variants)? Or is it just deep vg lore known only in our lab?

I am just hearing that Rust contains a type `Infallible`. Its description, "The error type for errors that can never happen.", sounds like the tagline for someone's next startup. doc.rust-lang.org/std/convert/...

This double helix is not double helixing correctly.

One day I will ... write out this database (in a graph orientated, Json compatible data format with Rust bindings). The one graph to rule them all (though @benedictpaten.bsky.social's Cactus graph is pretty darn close to the graph to rule them all from the genomics side)

I found a paper in the wild today where I couldn't click through to the cited references, because the DOIs for them appeared to have been sampled from a large language model instead of actually looked up, producing plausible-looking but wrong links.

SAVE THE DATE! Stoked to organize the 2026 Santa Cruz Developmental Biology Meeting with @rashmi-priya.bsky.social, @lowelab.bsky.social, and Shelbi Russell. Come learn about Biomedicine, Biomechanics, and the Biosphere, August 24-28, 2026. Registration dates, etc., coming soon! Please RT

Going through @samuelhorsfield.bsky.social presentation on pangenome graphs in comparative genomics, courtesy of @training.ebi.embl.org. Fascinating tidbit on history of alignment based sequence graph - it goes all the way back to 1989 (Hein), era of Apple IIs and IBM PS/2s. Great talk! 💻🧬🦠🧫

Going through #pangenome lecture from @camillemrcht.bsky.social I missed yesterday. It looks like I get a shoutout on a slide! 🥳 Fantastic presentation, love the conceptual connection between traditional natural history collections and the modern bioinfo repos 🧬💻 www.ebi.ac.uk/training/eve...

If you know of any scientists, historians, journalists, or anyone else working this beat that aren't already included, please let me know so I can add them!

The T2T zebra finch genome has hatched! 🐣 🧬 @vertebrategenomes.bsky.social

🦒Long read giraffe is out!🦒 Mapping long reads to pangenome graphs is ~10x faster than with GraphAligner, with veeery slightly better mapping accuracy, short variant calling, and SV genotyping than GraphAligner or Minimap2

Also note: for comparison speed, 1-bit hashes beat everything else (top-right red line here). Because each bit is an independent sample, the entropy is very high. (Whereas comparing 8-bit sketches loses some information, because if two 8-bit values differ in the first bit, the other 7 are unused.)

Here are the results in terms of the number of projects. The number of funded projects in FY2025 is 4014 fewer than the number for FY2024. 2/3

I have eaten the precisionFDATruth Challenge v2 dataset that was in the NIST Public Data Repository and which you were probably going to cite in your paper Forgive me it takes 2.85 minutes to load vendor.js

Is the #precisionFDA Truth Challenge v2 dataset in NIST's Public Data Repository under doi.org/10.18434/mds... meant to be mysteriously missing?

"We present exciting and novel new findings on the topic of the gel I'm about to run, with confirmatory experiments I'll run next Tuesday..."

for some reason i thought being a professor would involve more mentoring and research and less filling out disclosures concerning whether plants and seeds were used in my computational study
