- Reposted by Grant KinslerSpaceBar: a cellular barcoding approach for simultaneous analysis of cell clonal and spatial identities. www.nature.com/articles/s41...
- Excited that SpaceBar is now out in Nature Methods!🥳 We combined clone tracing with spatial transcriptomics to untangle what drives gene expression in tumors: a cell's identity or its neighborhood? Most genes were driven by location, but some showed strong clonal patterns. rdcu.be/eVhpc
- We designed SpaceBar to be as easy to use as possible: Cells are labeled via lentivirus transduction, and barcode detection works with any standard imaging-based spatial transcriptomics workflow. w/ Yael Heyman and @arjunraj.bsky.social Check out the thread from the preprint for more info!

- Reposted by Grant Kinsler🗞️ New preprint from the lab, led by our postdoc Ana Garoña (not on here) in collab with @andreagiometto.bsky.social: “Experimental evolution of cellular miniaturization reveals a mechanism for cell size evolution”, aka: “honey, we shrank the yeasts!” 🎥 www.biorxiv.org/content/10.6...
- Reposted by Grant KinslerSo excited to share this work led by @alexrob.bsky.social with Ben Kerr! We investigated a poliovirus capsid inhibitor that exploits a breakdown in the genotype-phenotype map to prevent drug resistance evolution. Or does it? See Alex's thread, but a few extras: #socialviruses #evosky #virosky 🧪
- My first lead author paper is out with Ben Kerr and @alisonfeder.bsky.social! We found that making an antiviral too strong can sometimes make resistance easier to evolve. This has implications for how we design drugs, choose doses, and think about viral evolution in the face of treatment. (1/n)
- Reposted by Grant KinslerThrilled to finally share the magnum opus of my PhD that focuses on the genetic basis of evolutionary change! Specifically, we know we can map the genetic basis of a trait, but can we tell which genes will underlie the trait shift when it evolves? doi.org/10.1101/2025...
- Reposted by Grant KinslerI am so excited to share new work on a TE insertion that regulates iridescence in swordtails, led by fantastic grad student @nadiahaghani.bsky.social and with help from many coauthors! In a time that has been so difficult to navigate, this & other projects have kept my spirits up: shorturl.at/NE65A
- Reposted by Grant KinslerHow is functional variation at large-effect loci maintained in natural populations, even as environments change? In a paper led by @mkarag.bsky.social, we tracked known pesticide resistant alleles in outdoor 𝘋. 𝘮𝘦𝘭𝘢𝘯𝘰𝘨𝘢𝘴𝘵𝘦𝘳 cages & inferred selection and dominance from temporal sequencing data.

- Reposted by Grant KinslerOne of the most exciting works of my career, years in the making. We used high-throughput precision genome editing to test the fitness effects of thousands of natural variants. Our findings challenge the long-held assumption that common variants are inconsequential. www.biorxiv.org/content/10.1...
- Reposted by Grant KinslerOur latest work is out in Nature today. In this paper, we introduce an improved version of NanoSeq, a duplex sequencing protocol with <5 errors per billion bp in single DNA molecules, and use it to study the somatic mutation landscape of oral epithelium in >1000 people www.nature.com/articles/s41...

- Reposted by Grant KinslerThe constant barrage of terrible news on bluesky has made me feel weird about promoting papers, but people in the lab have been doing so much amazing work over the past few months that I want to share a few brief teasers/links:
- Reposted by Grant KinslerHow common are frequency dependent fitness effects? New preprint out today 👇 doi.org/10.1101/2025...
- Reposted by Grant KinslerBittersweet to be leaving @docedge.bsky.social after a wonderful postdoc, but excited to share that I'm joining @uoregon.bsky.social next month as an Assistant Professor in the Department of Data Science.
- Reposted by Grant KinslerI'm excited to announce our new biorxiv preprint, wherein we investigate the evolution of the weirdest genetic locus I've ever seen! Behold the tgr genes of the social amoeba, which mediate self/non-self discrimination during facultative multicellularity 🐅 🧵 1/ www.biorxiv.org/content/10.1...

- Reposted by Grant Kinsler1/27 We have a new paper out! Turns out that snowflake yeast have been hiding a secret from us - they've evolved a (very!) crude circulatory system. Not with blood vessels or a heart, but through spontaneous fluid flows powered by their metabolism. 🧪🔬 www.science.org/doi/full/10....

1/n 🧵 Excited to share our new paper! We developed a framework to reveal hidden simplicity in how organisms adapt to different environments, particularly focusing on antibiotic resistance evolution. #EvolutionaryBiology #MachineLearning - Reposted by Grant Kinsler[Not loaded yet]
- Reposted by Grant KinslerWhy is sex so common if it's so costly? Super excited to share our new preprint “Sex decreases the pleiotropic costs of local adaptation”, where we bring a new angle to this age-old evolutionary question. Co-led by Parris Humphrey, in Michael Desai's lab. Short thread here: (1/n)

- Reposted by Grant Kinsler1/ Hey y'all, I'm excited to share my latest paper, which is out now in PNAS! We introduce FAVA, a statistical framework to measure compositional variability across microbiome samples. If you want to measure variability across a stacked bar plot, FAVA is for you! Paper: doi.org/10.1073/pnas...
- Excited to be co-chairing the Molecular Mechanisms in Evolution GRS this year! Please submit an abstract by this Sunday (3/16) if you want to be considered for a talk!
- Reposted by Grant KinslerI’m thrilled to share my first ever publication, now published in PNAS! www.pnas.org/doi/10.1073/... With mentorship from the amazing @ksxue.bsky.social, I looked at how the outcomes of species introductions to microbial communities are influenced by the number of introduced microbes.

- Reposted by Grant Kinsler1/46 Hey folks, we have a new paper out on the MuLTEE. Strap in and I’ll tell you the story of how this “little paper on polyploidy” turned into the most data rich paper our lab has produced, largely thanks to the leadership and work ethic of @kaitong25.bsky.social. www.nature.com/articles/s41...

- Reposted by Grant KinslerVery excited to have this paper officially out. This one is pretty special... Unfortunately, @kevinwoodum.bsky.social passed away when this paper was in its final stages. He was my biggest supporter, and I miss him deeply as a mentor and friend.
- Evolution of antibiotic resistance #AMR can lead to collateral resistance/sensitivity to other drugs; @jeffmaltas.bsky.social &co show that these effects can fluctuate over time, needing precise timing & stochastic control models to optimize treatment strategies 🧪 @plosbiology.org plos.io/3C2Ao1y

- Do mutations that drive evolution improve many traits or few? Does this change over the course of evolution? Excited to share our work in PLOS Biology exploring these questions in the first 2 adaptive steps w/ Yuping Li, @gsherloc.bsky.social, @petrovadmitri.bsky.social 🧵 doi.org/10.1371/jour...
- Theory predicts that adaptation should be slow and gradual, driven by mutations that incrementally improve the organism one trait at a time. However, work from microbes, cancer, and other fields often find LARGE mutations that improve multiple traits at once. 2/n
