New preprint! We unexpectedly discovered that some Caenorhabditis species delete parts of their somatic genome early in development, which fragments their chromosomes and eliminates key germline genes. Multiple lines of evidence suggest this bizarre process was present in the ancestors of C. elegans

I'd only dabbled with napari, but needed to use it for a paper we're writing. This is a quick post about getting started: from installation to a folder full of thousands of processed images, with gotchas along the way.

What a gem from @dudinlab.bsky.social @gautamdey.bsky.social @centriolelab.bsky.social in Cell! Expansion microscopy atlas of >200 eukaryotes comparing cytoskeletal architectures revealing structures not seen before. Stunning visualisation! Exactly the kind of transformative cell biology we need.

Zohran Mamdani looked at a clock and said he knew it was 6pm, and in fact it was 6pm, but he didn't _know_ that; he merely had a justified true belief that it was 6pm, since in fact the clock had stopped that morning at 6am.

@joann-trejo.bsky.social, @marymunson4.bsky.social and I have a commentary in @natcellbio.nature.com on recent attacks on DEI in biomedical research: "If scientific research, especially biomedical research, is meant to serve everyone, then it requires that everyone has an opportunity to participate"

The Skagit River is my new favorite river. It's a beautiful, diverse, glacial watershed. All 5 North American salmon species, steelhead, coastal cutthroat, bull trout, & dolly varden are all native & extant. It's an salmonid paradise that aptly means "place of sanctuary" in native Lushootseed. 🐟

Took a late afternoon hike through the woods down to Kyoto with the kids today — I couldn't manage to focus well but there was absolutely a persistent, full-color rainbow streaking through this (ジョロウグモ) spiderweb! About 3 in the afternoon with the sun already getting low.

A selenium-binding protein contains the sequence "SELEN…" - OK, not that surprising, I guess.
Are there any unlikely coincidences in a protein sequence akin to the prescient name of Su(var)3-9? A kinase that has "KINASE" as part of its sequence for example.
