Hot off the presses and so so thrilled. Thanks to @inaturalist.bsky.social + computer vision we found something beautifully simple: Red and orange flowers bloom later than all the other colors in the eastern United States. Paper here: authors.elsevier.com/a/1kwzh3QW8S...

Aaah! New preprint from the Sethuraman Lab has dropped! Tamsen and I have been working on this for a while, and we can’t wait for your feedback. Short thread on our swanky new polyploid genome simulator, DemographiKs, and its functionality.
Hidden in Plain Sight. How Ks histogram dynamics can reveal and obscure ancient whole genome duplications. https://www.biorxiv.org/content/10.1101/2025.11.19.689290v1

I’ve released a tool to sketch and edit phylogenetic trees!
yawak.jp/PhyloWeaver/

Load a Newick file and intuitively add/remove/resize branches.
Useful for quick conceptual trees, extracting subtrees, or turning ideas into Newick.
PhyloWeaver – Interactive phylogenetic tree editor
Edit and visualize phylogenetic trees directly in your browser. PhyloWeaver lets you interactively rearrange tree topologies and export high-quality figures for publications and presentations.
