New preprint: a phylogenomic tree of Elateriformia (fireflies, click, jewel, soldier beetles and relatives). 195 taxa, 31 of 34 families, up to ~4,200 genes. The group goes back ~285 Mya, and soft bodies and neotenic females evolved independently at least 15 times. www.biorxiv.org/content/10.6...

I became a biologist because of a museum exhibit. Real artifacts tell stories that are more powerful than anything we can get from scrolling. They are part of our engine for training the next generation of scientists. 🧪 scienceforeveryone.science/the-awesomen...

The awesomeness of museums
Genuine artifacts tell the richest stories that fill our souls. And they fuel the scientific enterprise.

The Academy of Natural Sciences museum is closing, but all eyes are on its specimens — all 19 million of them
"Profound concern" over the fate of the Academy and its internationally significant collection.

New preprint: 338 coleopteran genomes reveal exceptional rearrangement variation compared to other insect orders. Big congrats to @arf-mln.bsky.social, for getting this giant piece together. Big collaboration of @joanameier.bsky.social's and my groups. 🧵👇 doi.org/10.64898/202...
Phylogeny of 338 species with tips painted by the chromosomal ancestry of their contemporary genomes (well separated colours indicate only few changes, while blending indicates rearrangements). Colouring of the branches is by the number of rearrangements. The ring between paints and phylogeny indicates wether the chromosomal rearrangement was fusion dominated (brown) or fission dominated (teal) process.

The fate of mountain biodiversity in a warming world
Nature Reviews Biodiversity, Published online: 25 May 2026; doi:10.1038/s44358-026-00167-9Species living on mountains are thought to be especially vulnerable to ongoing climate change. This Review explores past and present responses of mountaintop species to climate warming to help to understand mountain species’ vulnerabilities and resilience to future warming.
