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!

Cartoon strip, someone believing the universe is elegant, made of lisp programming language coding. But then god saying it's actually just held together with perl
I often think of DNA like this comic

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...

Two more #kakapo nests found on Anchor today: Waa on 3 eggs and Hauturu (pic) on 2.
Also two matings last night:
Anchor: Konini 💚 Quill
Whenua Hou: Hera 💚 Tutoko

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.

I use a vacuum with the attachment removed. And have also gotten some sundews, which are certainly pretty, but have caught 2 out of ∞ bugs so far
Exploring #PAG33 and San Diego for the first time! If you're interested in knowing more about why bird microchromosomes are so hard to sequence, come by poster 287 this afternoon!
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.

#kakapo breeding seasons are always roller coasters.
☹️ Young male Tau Kuhurangi has died on Pukenui, likely from a wing injury. Population is now 236.
🙂 Second mating of the year: Esperance (pic) and Ian. #conservation #parrots #birds
We made a podcast for @bioprotection.bsky.social Have a look if you are interested in all things that start with b, Nick singing 80's songs or, perhaps more importantly, why and how to save the planet. bioprotection.org.nz/under-the-le...
I'm delighted to share that our publication 'Nest survival models and genomics illuminate hybridisation attempts, guiding culturally informed management to recover a critically endangered seabird' is out now in Animal Conservation @animalconserv.bsky.social! doi.org/10.1111/acv.... 🧵 1/9

Big bluestem has been a lovely and complex system to work with for the majority of my PhD and will always have a piece of my heart! Very excited to share this work with the community.
It’s Tuesday folks, and you know what that means:
