Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).

A brief 🧵 (carried over from the old place)

Petunia hybrida has been bred into an incredible diversity of colors and patterns.

Most arise from mutations in the anthocyanin pathway or post-transcriptional gene silencing that turns pigment genes on and off 🧬🎨

Striking signal for much above-normal temperatures across California, the Great Basin, northern Rockies and Desert Southwest from March 15-20. Temperatures will be more typical of summer than early spring (potentially 25 degrees above normal) in many areas and monthly records could be shattered.

🌿 Postdoc opportunity in plant evolutionary ecology/genetics!

My lab in the Dept. of Ecology & Evolutionary Biology at the University of Michigan is recruiting a postdoctoral researcher to start Fall 2026.

We study plant adaptation, using weeds as model systems.

Hahah correctly guessed they'd named it after the county.

Great to see such a large crowd out today! #standupforscience

Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success. Data source: https://report.nih.gov/nihdatabook/report/302

The data is in: the NIH goalposts have shifted.

What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards.

Another manifestation of how HHS policies have led to fewer awards and less science.

Here is the "effective payline" for each institute, estimated (by Claude) as the percentile where one can expect 80% probability of funding from a logistic regression fit. The effective payline has gone from a historic ~12% to 6% in 2025.

7/ In reality, my colleagues still inside NIH tell me that their assessments are largely ignored.

Once a grant or application is picked up by the tool, they are almost never able to move the grant forward as is - regardless of the scientific justification.

Current NIH leadership want you to think they are using rigorous, consistent & scientific processes to screen studies to align them with agency priorities.

But the process that they have put down on paper is a sham.

It’s important to know NIH is not following its own guidance. Here’s why:

One protein. One pathway. A whole germline fate.

you're just jealous that all these horses are off living their best lives and totally didnt go to the glue factory.

FY26 is in a worse place Evan than FY25. NIH barely got funding out last year. This is very worrying.

Recently we're working with SNPs from whole genome assemblies to estimate ARGs. It's a pain to go from alignment files to vcf, keeping track of masked and invariant sites. So we wrote a snakemake/SLURM pipeline. Hope it's useful to others, and don't hesitate to post issues if there are problems!

@pratikkatte.bsky.social and I just released Lorax 🌲, a tool for interactive exploration of biobank-scale ancestral recombination graphs (ARGs).

If you’ve ever wanted to scroll across the ancestries of thousands of genomes… this is for you.

We are happy to announce that the Internal Conflicts and Organismal Adaptation STN has funding available to support several small travel grants for early-career researchers to enable them to visit another laboratory. What is this for? This funding is intended to enable early-career researchers – PhD students, postdocs, and junior research fellows – to visit another laboratory. In so doing, they can learn a new method or approach and/or initiate novel collaborations in the form of manuscripts, grants, or fellowship proposals. We envision that these visits are short stays (a week up to a month) but longer stays are also permitted. Who can apply? Early-career researchers, i.e. PhD students, postdoctoral researchers, and up to junior research fellows (i.e., those in tenure-track positions but not tenured yet). Priority will be given to ESEB members and to trips that reflect novel collaborations (i.e., between people who have not previously collaborated, defined by co-authorship). ESEB membership is cheap (€40 annually, €20 for students) and discounts are available for residents of low to upper-middle economy countries (see ESEB website for details). Membership also comes with additional benefits such as reduced fees for conference attendance. What can be requested? Applicants can request funding to support a short research visit at another institution. The maximum amount of support that can be requested is €1.000, to be used for travel and accommodation. The provided funding cannot be used to cover research costs, wages, and/or stipends. ESEB policy states that we should minimize the environmental impact of e.g. travel; therefore, we will only support travel by airplane if the distance travelled exceeds 500 km and the travel time with alternative forms of transport would be more than 6 hours. How to apply: Download the application form and fill it out. Obtain two short letters of support, one from your supervisor/line manager and one from the host research group explai…
