Our paper on myxozoan genomes is out now in G3! See thread below for a brief recap (slight change of title from the preprint, same content).

Thank you also to @arunsethuraman.bsky.social for handling the manuscript and @joannamasel.bsky.social for helpful comments.

Really, really happy that our work on microsporidian genomes is now out in @plosbiology.org! A huge thank you to my coauthors, my supervisors @mblaxter.bsky.social & @marakat.bsky.social, the editors @roliroberts.bsky.social & Joseph Heitman, and the reviewers ❤️ plos.io/48HsAQJ

My parents were contemplating a holiday in Sweden in October, and pointed out it was recently 30°C in Abisko

LLMs would make great conspiracy theorists though. I was trying to identify the the hashing function used to map an identifier to a directory path, and the model claimed that my system is compromised because the output didn't match the prediction. Nope, my guess about the input was wrong...

Have long-read data and want to know what you've really sequenced, and how much of it? Reliable taxonomic labels are often scarce if the target is from a less well-explored group. Fortunately, 2D embeddings from a VAE can tease apart different organisms in read sets:

I'm more bemused by the lack of exterior blackout shutters. My grandma's house in Germany was nowhere near as warm as my apartment in Cambridge last week, even though it had hit 36°C there. It's as though I never left my top floor Philly row house apartment that didn't have window AC in the kitchen

Proud to have authored this review with brilliant people. Hope we inspire more attempts to sequence the #protist genomes that are within reach! Huge thanks to Alexandra Schoenle for leading. #ProtistsOnSky

New preprint! We generate 40 new high-quality microsporidian genomes from infected arthropod hosts that were sequenced to create reference genomes by the Darwin Tree of Life project. 8 of our genomes are chromosome-level, and we’re able to generate Hi-C data for 7! 🧬

I think you can keep the topology fixed in FastME if you tell it to only optimise the branch lengths

There was an edited extract from the O'Sullivan one in the Graun a few days ago (a bit too anecdotal for my personal liking).
