Delighted to see this paper with @anaignatieva.bsky.social now published in Genetics! academic.oup.com/genetics/adv... We tackle a thorny issue arising in statistical tests for genetic interactions (epistasis) using ancestral recombination graphs (ARGs)... 🧵

First pop gen paper from our lab! We find repeated evolutionary turn over of sex chromosomes in darters contributes to reproductive isolation. Turnover may be an escape hatch to resolve mitonuclear conflict & neo sex chromosomes evolved via a rare recessive mutation. www.biorxiv.org/content/10.1...

Very happy to share our work on signature SBS5. See Molly's thread for a short summary

In these dark times, it comes as a rare pleasure to highlight @natanaels.bsky.social ‬ & @marcdemanuel.bsky.social's work on germline and somatic mutations in humans. 1/n www.biorxiv.org/cgi/content/...

Trump admin planning to change student visas from lasting for duration of academic program to fixed 4-yr term, and then much harder to renew Could destroy US ability to attract global talent, particularly those seeking advanced degrees in STEM. The median time to complete a PhD is 5.7 yrs per NSF.

This seems like a wildly useful resource for students applying to college and trying to compare costs - collegetables.info The cost after need-based financial aid varies widely, and often not in ways one might expect

Why do males and females often differ in traits? The expected answer: selection. But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism — even when male & female optima are the same

Not sure how many scientists here have tried Claude Code or similar command line coding assistants. I had a complicated family property tax problem that was best solved by a brute force Monte Carlo simulation approach, so I spent a few days coding up and analyzing a model with Claude Code.

I'm thrilled that my lab at NYU is now supported by an NIH MIRA grant! I'm looking to hire 1-2 senior lab members (outstanding postdoc candidates or experienced staff scientists) with expertise in computational or statistical methods in human genetics or genomics. Please share!

hey folks! so looking forward to seeing everyone at @sse-evolution.bsky.social! if you have space on your schedule, come check out the Kreiner lab contigent on Sunday morning in the Adaptation VI symposium.

Let me remind you: we don't have kings in America — and I won't bend the knee to one. Never stop speaking out and showing up, Illinois. This is what democracy in action looks like.

Here’s a New York Times photo of the Chicago “No Kings” rally. NYT said the march that followed spanned at least 10 blocks.

The #NoKings march in Chicago stretched for blocks and blocks and blocks - No monarchs here! (except for butterflies and drag kings + queens)

Excited for our publication on how the geographic scale of a sample affects the discovery of rare, deleterious variants to be out this week. With a mix of theory, simulation, and data analysis, we show when samples are narrow vs broad, the number of variants discovered and their frequencies change

I'm excited to announce that I'll be starting a lab at UCSF in the @ihgatucsf.bsky.social and @ucsf-epibiostat.bsky.social in July. We'll work at the intersection of statistical genetics, population genetics, and machine learning.

I have an opportunity to hire a staff scientist for my lab. Looking for someone with outstanding skillset in ML/statistics, genomics applications; interest in mentoring, strong publication record, PD experience required. Email CV to me+cc my assistant (see 'contact' on my website). Ad to follow.

Out today in @pnas.org! www.pnas.org/doi/10.1073/...

Jennifer Blanc and @jeremyjberg.bsky.social use theory and simulations to study the process of testing for an association between polygenic scores and axes of ancestry variation when confounding factors are present. Learn more about their findings in #GENETICS: buff.ly/EmKpXyP

Our lab is moving! I’m thrilled to be joining the Department of Ecology & Evolution at the University of Chicago this fall. I’ll be recruiting PhD students so please spread the word and reach out if interested!

When should adaptation arise from a polygenic response versus few large effect changes? https://www.biorxiv.org/content/10.1101/2025.05.15.654234v1

Racist and sexist roots in the cancellation of NSF grants under Trump: Grants with female PIs canceled 2x more than men Grants with Black PIs canceled 4x over White PIs Grants with Hispanic PIs canceled 2x over White PIs Grants with PIs with disabilities canceled 2x more than without

Postdoc job opportunity! We're looking for ECR in evolutionary genomics to study the relation between intra-specific gene expression variability, polymorphism, and macro-evolutionary rates. We have the data in 3 fishes & amphioxus, just waiting for your expertise and enthusiasm! tinyurl.com/3aewk286

It's going to be increasingly important to read foreign news coverage of US politics as the domestic US media gets more afraid of continuing threats & intimidation from the Trump regime

It's infuriating that grant mechanisms intended to improve diversity in science are frozen-those apps are identical to other career development award apps-but we advised students from underrepresented groups to apply to the special mechanism. And now they, specifically, are losing their funding.

Several Columbia Univ student journalists are suspended after covering protests (while wearing press ID) in the main library. Their access to campus is blocked, and they can't take final exams. Also: Columbia's acting president is a former ABC journalist www.columbiaspectator.com/news/2025/05...

Top scientists are cutting staff. Postdocs are leaving the country. Promising students – can't find labs. How the Trump cuts to science are playing out. @uwnews.bsky.social www.nbcnews.com/science/inno...

And then called the NYPD and violently arrested them, while sending out emails about the terrible disruption to studying that was caused by peaceful protesters in one room of one library. There aren't words to describe how disgusting and hateful this is.

Thirty-eight of 43 experts cut last month from the boards that review the science and research that happens in laboratories at the National Institutes of Health are female, Black or Hispanic, according to an analysis by the chairs of a dozen of the boards.

[Please share] 📢‼️ I have 2️⃣ postdoc positions advertised at the Swedish Museum of Natural History: Postdoc on "Theory of adaptive radiation" recruit.visma.com/spa/public/a... Postdoc on "Homoploid Hybrid Plant Genome Evolution" recruit.visma.com/spa/public/a...

I'm hiring a postdoc! Searching for a candidate interested in the process of speciation to come join me at Georgia Tech in Atlanta -- an exciting place with a growing core of eco-evolutionary researchers. Various skill sets will be applicable. Please share!

Notably, Booker is still talking about policy and staying on message. Much earlier into their own filibusters, Ted Cruz was reading Green Eggs and Ham and Thurmond was reading from the phone book.

This pointless stunt by Cory Booker is accomplishing nothing but drawing attention to the Trump administration’s wrongdoing and delaying the work of the Senate and energizing the Democratic base and, wait, hang on, let me come in again

This is one of the best features I have seen on blue sky yet- a custom feed of papers from people you follow. I had to un-follow the various biorxiv channels, as it was dominant, but now I am seeing lots of cool papers from people I follow. Great work on this feed, @paper-feed.bsky.social team!

Can anyone recommend a good foundational bioinformatics course (in person preferred) for a molecular biology PhD student interested in improving on bioinformatics/command line tools for WGS projects? Topics related to his project: variant calling, long-read sequencing, HMMs

NEWS: Last night, the Department of Homeland Security detained a Palestinian who helped lead the Columbia encampment. Agents told him his visa was revoked. He said he had a green card. They were confused—then said that was revoked too. His attorney demanded a warrant. Agents hung up instead.

Just in case you thought that removing DEI criteria would mean that everyone is competing equally: NIH is removing grad students from underrepresented backgrounds from the applicant pool altogether. Their applications will not be considered. Other students, not from these backgrounds, will be.

Are you an HHMI-funded researcher affected by the cancellation today of IC3 (Inclusive Excellence 3)? Find me at [email protected] or on Signal: meredithwadman.13

What should you do in that case? MOST IMPORTANTLY: Don't respond right away. Bring it to your sponsored research office first and consult with them. This prior thread has some practical tips for contesting an award suspension or termination:

Just got word that our Howard Hughes Medical Institute (HHMI) Inclusive Excellence 3 (IE3) Grant was being canceled. All 100+ institutions. So even private funding is susceptible to this administration’s unraveling of DEI initiatives
