Vibe-coding spaghetti: Unpacking an AI metaphor for biology I recently saw a post on Bluesky just saying “Coconuts”. Intriguing! Underneath was a screenshot of a tweet which was even more intriguing. The tweet said: “A techbro told me that biolo…

I actually really like the coconuts story being a myth. We come up with all sorts of things that we think are true then more evidence and genome research comes out and that long held belief is kicked out for something else.

Thanks for sending this!

New preprint! We sequenced 175 'Alalā (Hawaiian crow) genomes to understand why >50% of eggs fail to hatch in a species recovered from just 9 individuals. What we found was a both exciting and surprising. www.biorxiv.org/content/10.6...

How do we obtain the correct frequency dependent formula for random effects in linear mixed models?

We introduce a principled procedure on how to dump population genetics to linear mixed models.

The youngest #kakapo chick on Pukenui/Anchor Island: Hanariki-A2, at 3 days old. It's a tiny 42g, but doing OK. Managed to keep it mostly dry on a very wet night. #kakapo2026 #conservation #birds

Hoiho - the world’s rarest penguin, fewer than 150 mainland pairs left

🐧We researched one of the world’s rarest #penguins. The yellow‑eyed penguin (aka hoiho/takaraka) isn’t one homogeneous species after all!

Insect research has used Drosophila as a model organism for over a century. But today’s tools now open up a much wider spectrum of insects which deserve to be studied. See the recent commentary in @fly-journal.bsky.social by @peterkdearden.bsky.social, ‘Why just fly?’ doi.org/10.1080/1933...

Very excited about this latest work led by @jermp.bsky.social! Since it's initial release, SSHash has served as the basis for several other tools (Fulgor, piscem, etc.). It was already very fast. It is now *substantially* faster!

A nice opinion paper (doi.org/10.1016/j.pb... ) from @anneroulin.bsky.social that highlights the need for caution when generalizing about the importance of TEs in local plant adaptation.

Now published in Algorithms for Molecular Biology: link.springer.com/article/10.1.... Key message: a tiny CNN model with 7k parameters can capture main splice signals across vertebrates+insect and halves the minimap2 & miniprot junction error rate. I always use this new feature now.
