Cannot be more excited about the lineup for the inaugural Function of Evolving Systems GRC conference I am co-organizing with the amazing Joy Bergelson. Less than a month away: August 9 - 14, 2026. Still a few spots left! And do check out the amazing list of speakers: www.grc.org/function-of-...

‘A society that loses science loses the future’ says Neil Shubin, as he starts his tenure as the NAS President @neilshubin.bsky.social - thank you for speaking to us @nature.com 🧪 #AcademicSky www.nature.com/articles/d41...

How good is MiniBWA, the successor to BWA? To test it, I ran MiniBWA on sequencing from 76 different species, comparing mapping speed, rate and accuracy with BWA MEM. In short, it's really good. If you map short reads, it's well worth your time. andrewcarroll.github.io/2026/06/30/t...

Votes for the 2026 SMBE election have been counted, and we are happy to announce that Dmitri Petrov will be the next President-Elect of SMBE, with Esther Betran and Sohini Ramachandran as the new Councilors. They will join the Council in 2027, serving 3-year terms. Congratulations! #society

Day 4 at #SMBE2026 and the keynote talk is on “Evolution in the human gut microbiome” 🦠🧬 Associate Professor Martin Sikora welcomed Associate Professor @nanditagarud.bsky.social from UCLA to the stage where she shared a very interesting talk with the @official-smbe.bsky.social community 🤩

Please welcome @vscooper.micropopbio.org as the new ASM President and Federico Sisti, Ph.D., as President-Elect. They begin their terms on July 1. ASM congratulates its new & continuing leaders and looks forward to their leadership in advancing ASM’s mission. asm.social/2Zx

😮 @danielgorelick.bsky.social @biologyopen.bsky.social www.nature.com/articles/d41...

Sad to be missing #SMBE2026 in general but missing @nanditagarud.bsky.social plenary is particularly painful!

We are very excited to share our latest. We thought that soft sweeps would be the only type of sweep spreading across human gut microbiomes. Turns out many are hard! Reach @peterlaurin.bsky.social 's thread on why! And tomorrow at #SMBE2026 I will share this work and more!

This is wonderful news!

Very pleased with the response and still have spots & funding especially for students/postdocs. Sign up soon before it gets full. If you are working at or wanting to learn about the intersection of functional biology and ecology/evolution, you would get a lot of it! www.grc.org/function-of-...

Please join us in NH (perfect place to be in August!) for this inspiring conference organized by @petrovadmitri.bsky.social and Joy Bergelson. Very interdisciplinary, so I look forward to learning tons of new concepts. www.grc.org/function-of-...

New research in #G3journal leverages ultra-long Nanopore #sequencing to identify structural variants. 🧬 @jahemker.bsky.social, @petrovadmitri.bsky.social and the team also present new high-coverage (>100x) long-read assemblies for #Drosophila inbred lines. 🪰 🔗 buff.ly/j3v3GAY

Excited to be at #PEQG26! I have a poster tonight on measuring selection on intraspecies variation in large microbial communities (415W), would love to hear what folks think!

I agree. Sorry I missed your paper. I does remind me of this one doi.org/10.1371/jour... by @petrovadmitri.bsky.social

I have started updating my website because I am no longer at San Francisco State. I also wrote on my website landing page that I am writing a book about my favorite topic: evolution of drug resistance. That's my biggest goal for the year! pleunipennings.wordpress.com

wow — the preprint host, arxiv, is banning authors for a year if they submit papers with hallucinated citations 🤖

Help needed! Does anyone have experience extracting nuclei from flash frozen tissue? Especially helpful if it is fish skin or tail tissue! We are trying to get some precious melanoma samples processed for snRNAseq but are having issues with either nuclei number and/or quality

Excited to share this new pre-print from the fantastic @kelsiehunnicutt.bsky.social! Kelsie put together a thoughtful and thorough review on hybridization in animal evolution: ecoevorxiv.org/repository/v.... She tracks notable shifts in perspectives on the study of hybridization through time.

Do you know any students who are planning to apply to graduate school this cycle? Encourage them to apply to the Biology Preview Program! We provide intensive workshops to help students w/ their applications + 1:1 mentorship.

Our paper entitled "The persistence and loss of hard selective sweeps amid admixture in ancient Eurasians" is now out in PNAS! www.pnas.org/doi/abs/10.1.... A really fun and informative collaboration with @mharris.bsky.social, Ziyi Mo and Adam Siepel. (1/n)

It's official-- my promotion to Associate Professor with Tenure has been approved by the Executive Committee of the MIT Corporation!! This is a surreal moment and I owe my deepest gratitude to the members of my lab, collaborators, mentors, and colleagues who made this possible. Thank you!

Simons Graduate Fellowships in #Ecology and #Evolution #science #scienceSky #evoSky www.simonsfoundation.org/grant/simons...

Please share widely! We will imminently be posting a technician position in our lab group since @rheasood.bsky.social is off to grad school 🙌! If you know of anyone excited about molecular biology, evolution, and functional genomics please have them reach out (schumer at stanford). Start date ~June

I agree with your framing... We have an example of this in a wild plant species for a strong-effect phytochemistry QTL: www.nature.com/articles/s41... Granted it's just 1 locus but maybe a useful proof of concept. Were the reviewers arguing balancing sel = heterozygote advantage?

I am hiring a popgen postdoc! Looking for a creative scientist to join us at USC to investigate recessive variation and complex traits in model or non-model species. The project is funded by a multi-year NIH grant, contract can be renewed. Job add & details 👇🏽 usccareers.usc.edu/job/los-ange...

We are revising this ms www.biorxiv.org/content/10.1... and responding to reviewers who liked the paper but had issues with how we thought of balancing selection and its relationship to ecological, local adaptation 1/n

Our PhD student Kennedy Orwa, who studies applications of AI to health care, was hastily deported today to Kenya along with his 13-year-old son without opportunity to speak to legal counsel. King 5 reports that he held a valid visa that was rescinded without explanation.

The two papers: www.science.org/doi/10.1126/... and www.science.org/doi/10.1126/...

We’ve been talking in our lab meetings about sexual conflict and sexual dimorphism, and have some thoughts. What if animal genomes are far more sex-specific and less cosntrained than we assume? @linley-sherin.bsky.social pulled it all together here www.zoology.ubc.ca/mank-lab/pdf... 1/n

Very excited about this paper. Olivia did such a beautiful job and in particular tackled an analytically very hard question of whether different environments are limited by the same of distinct functions. Very curious what people think! 1/2

Gonna be some rad science -- @mollyschumer.bsky.social keynote and a bunch of good talks and posters. And I'll personally pay the registration of anyone who wants to come (it's free).

Jeff is way too generous. He and I will split it!

Coming up soon! Check out the excellent line up of talks! @jrossibarra.bsky.social bapg-conference.github.io

Some work from our lab by @grantkinsler.bsky.social , @kgslab.bsky.social and @petrovadmitri.bsky.social pioneered a new way to investigate these genotype-phenotype-fitness maps in microbes, using a top-down approach elifesciences.org/articles/61271. (4/n)

Really excited that this major work from my PhD is finally published in @plosbiology.org ! In it, we were trying to tackle a fundamental question in evolution - how do genetic mutations map onto evolutionary fitness? (1/n) journals.plos.org/plosbiology/...

Really neat piece of work in @plosbiology.org, inferring the hidden layer of "fitnotypes" that link genotypes to fitness, and finding surprisingly low dimensionality. From @oliviamghosh.bsky.social @grantkinsler.bsky.social @benjaminhgood.bsky.social & @petrovadmitri.bsky.social

Happy to share the final version of @oliviamghosh.bsky.social's paper on inferring low dimensional phenotype-fitness maps from high-throughput fitness measurements across environments. Fun collaboration with @oliviamghosh.bsky.social, @grantkinsler.bsky.social, & @petrovadmitri.bsky.social

Predicting the effect of a #mutation on #fitness is hard. @oliviamghosh.bsky.social @petrovadmitri.bsky.social &co use fitness effects of adaptive yeast mutants to show that underlying genotype-phenotype-fitness maps are low-dimensional but context-dependent @plosbiology.org 🧪 plos.io/4dLy2Ez

I think this is our lab's first paper in a proper ecology journal. We are now card carrying ecologists!

Really excited to see this work out now in Ecology Letters! May be particularly interesting to those thinking about life-history trade-offs and eco-evolutionary feedbacks, and how those may interact to maintain variation within natural populations. onlinelibrary.wiley.com/doi/10.1111/...

The conference is quickly filling up! Don't wait to sign up. We also received some funding and can offer fellowships to graduate students and postdocs. Won't cover the whole cost but will certainly make it much easier!

A question for biologists: we often talk about evolutionary novelty. What does “novelty” mean for you? What’s your favorite definition if any? Or just a rule of thumb for what is and isn’t novel.

David Botstein was one of the giants of genetics and genomics, and my mentor, colleague and friend for more than 40 years. I’m sad that he is gone, but his larger-than-life persona comes through here. www.nytimes.com/2026/03/20/s...

Really impressive study with a clear and very interesting conclusion. As @plantevolution.bsky.social says - scale matters - I wonder what the results would show if the sampling continued across more sites, and across more abiotic and biotic esp. disease states?

Very proud of this contribution. Beautiful and hyper careful work by @jahemker.bsky.social showing that not all long read assembles are created equal and at times it really does matter to have enough not just long but very long reads. Curious what you all think!

Proud that this work is now published! We hope it helps orient future #Nanopore long-read sequencing studies hunting for structural variants Also really happy to share eight new high-coverage (>100x) long-read read pools and assemblies with the #Drosophila community! doi.org/10.1093/g3jo...

Very proud of this paper, now officially out at PRX LIFE journals.aps.org/prxlife/abst.... Here @mrazo.bsky.social shows that geometry-aware autoencoder architecture can discover low dimensional phenotypic spaces traversed by evolution. 1/2
