"It is absurd to mindlessly decimate the workforce that has led the world in science over the past 75 years, and to willingly give up excellent scientists and talent," Beyer wrote. www.reuters.com/world/us/us-...

US science agency reclassifies hundreds of workers as probationary, US lawmaker says

National Science Foundation administrators reclassified hundreds of employees from permanent to probationary status in violation of labor contracts, according to a U.S. lawmaker and agency employee.

It's weirdly difficult to remember that Trump's popular vote margin was /less/ than Hillary's in 2016. Biden got more votes in 2020 than Trump got in 2024 and Trump surrogates all under-performed in congressional races. This is not a mandate, I don't get why it is being portrayed that way.

Somebody yelled at me for posting about Ganymede instead of /the state of things/ last night. I know we’re (almost) all on the same page here, but a Bluesky without cute cats, science facts, and dumb jokes would be bad for everyone.

Preprint finally out! I show that eco-evo feedback can drive a tipping point where genetic drift overwhelms adaptation. This can result in a contraction of a species' range border or range fragmentation. Fragmentation is abrupt and arises readily under rapid temporal change. doi.org/10.1101/2025...

Suggestion: Search up Energy Share programs that help people stay warm in the winter. Katherine and I are making a $10,000 donation to Energy Share of Montana today.

A new method for trimming alignments in #phylogenomics — PhyIN. It identifies and trims regions with high phylogenetic discord. Able to trim well even on single loci — an advantage for gene tree/species tree studies. #evolbiol #phylogeny 🧪http://doi.org/10.7717/peerj.18504 Some backstory... 🧵

PhyIN: trimming alignments by phylogenetic incompatibilities among neighbouring sites

In phylogenomics, regions of low alignment reliability and high noise are typically trimmed from multiple sequence alignments before they are used in phylogenetic inference. I introduce a new trimming...

I don’t plan on retuning to Twitter but I am curious to hear thoughts on the point of deleting all past posts before closing an account. Is this mostly performative or are there other reasons to do this?

Carl T. Bergstrom@carlbergstrom.com · 2y ago

My twitter account has been closed and locked since November 2022, but I had left the posts up until now. I just deleted the entire thing in 15 minutes, thanks to a great script from Luca Hammer: github.com/lucahammer/t... Thanks to @amyhoy.bsky.social and @thomasfuchs.at for steering me there.

Great to work with @ekopania.bsky.social, @jeffreygood.bsky.social, and everyone else on this project! I was happy to be able to present Emily's cool figure showing dN/dS of genes in different tissues and different time-points at Evolution a couple years ago:

A color figure (3) from the paper linked in the quoted post. The top panel A shows a drawing of the male rodent reproductive tract with different tissues shaded different colors, from dark blue to red, indicating median dN/dS values for genes expressed in those tissues. Below are colored cells using the same color scale from five different stages of spermatogenesis. Panels B and C below are graphs with points on the x-axise corresponding to the four cell stages shown above, with the y-axis for panel B being the proportion of genes under positive selection for each time point and for panel C being the proportion of genes expressed during that stage that are testis-specific. The points in panel B hover around the genome-wide average shown with a dotted horizontal line, while the points in panel C increase steadily above the genome-wide average, peaking in stage 4 (spermatids).
