I 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

Exited to have such a great set of speakers for Ancient genomes: perspectives on human biology and medicine The program is now online and registration is still open! registrations.hg3conferences.co.uk/hg3/frontend...

Exciting new study led by @ekerdoncuff.bsky.social and @meaghanmarohn.bsky.social on the evolution of Lactase Persistence in South Asia. www.biorxiv.org/content/10.1...

Save the date! ProbGen 2026 will be hosted at UC Berkeley, March 25 to March 28, 2026. Featuring keynote speakers @jkpritch.bsky.social and Sally Otto. More details soon...

@leonardoiasi.bsky.social High sharing of N. segments between populations except the earliest Out of Africa populations. Duration of gene flow inferred. Evidence of rapid - and + selection. Deserts of N. ancestry rapidly formed after the introgression. 🏜️ #HumanEvo25

Aneuploidy is the leading cause of pregnancy loss. In work led by @saracarioscia.bsky.social and @aabiddanda.bsky.social, we reanalyzed genetic testing data from 139,416 IVF embryos to discover variants associated with recombination phenotypes and aneuploidy risk. www.medrxiv.org/content/10.1...

Posting on behalf of Shamil Sunyaev: Eimear(Vice Chair) and I (Chair) are organizing the 2025 Gordon Research Conference (GRC) on Human Genetics and Genomics, which will be held on July 6-11, 2025 in beautiful University of Southern Maine, Portland, Maine.

Had the opportunity to present my work on Lactase Persistence in South Asia, in collaboration with Meaghan Maroon, at #probgen25! Excited to share our findings with this amazing community!

From the editors of @asm.org journals, a call to action! Below we discuss the U.S. scientific research enterprise and provide evidence and arguments we hope the ASM community can use to advocate for science. journals.asm.org/doi/10.1128/...

Despite the chaos in the world, I am excited to share our new paper just out in Mol Ecol. We studied the interplay between the effects of host plant variation and viral infection on physiological responses and gene expression in Melissa blue butterflies. onlinelibrary.wiley.com/doi/full/10....

Inexplicably, US administration has launched an unprecedented assault on science, on research institutions & on vital international organizations & initiatives. An assault on science anywhere is an assault on science everywhere; the global community must unite 🧪 www.nature.com/articles/d41...

CT friends! We are standing up for Science on March 7th in Hartford! Stay tuned for details — @centromellone.bsky.social @davidbreslowlab.bsky.social @gregggonsalves.bsky.social @luskinglab.bsky.social

Happy 37th birthday to the LTEE! the-ltee.org/history/

I'm very proud of my organisation for showing clear leadership during these challenging days. "PLOS will always anchor our decisions in our values and our principles. And we will continue to speak up vocally for open, independent science."

Reminder to call House Energy & Commerce Committee chaired by KY Rep. Brett Guthrie (202-225-3641) and Senate HELP Committee chaired by LA Sen. Bill Cassidy (202-224-6770). Call Guthrie’s regular office too (202-225-3501). Register your concern regarding:

To all people who value science as a source of truth, cures for diseases, and hope for our climate and future, here are 2 hard truths: 1) our current research ecosystem is already strained and very fragile; 2) If it gets broken it will take a generation or longer to repair. Here’s why: 1/n

Excellent story fleshing out hie midern humans migrated far and wide in Europe for the beginning, and when they made it with Neanderthsls: www.science.org/content/arti...

My summary of the new aDNA papers on Neanderthal interbreeding

Enthralled to see our work published in Science. This wouldn’t have been possible without the wonderful contributions of the team comprising @moorjanipriya.bsky.social @leonardoiasi.bsky.social @benmpeter.bsky.social @lauritsskov.bsky.social @matejahajdi.bsky.social and Alba!

More on the timing of neanderthal/sapiens admixture www.nature.com/articles/d41...

The first paper, lead by @arevsumer.bsky.social, Kay Prüfer and Johannes Krause, describes some amazing new genomes from Ranis and Zlaty Kun. See Arev’s write-up here:

The second paper is a systematic survey of Neandertal ancestry through time; a joint effort with @moorjanipriya.bsky.social ya.bsky.social’s lab at UC Berkeley, co-led by @leonardoiasi.bsky.social and Manjusha Chintalapati. Leo has a great summary of our main findings here:

Very excited to see our study published today, joint effort with @benmpeter.bsky.social group, co-led by @leonardoiasi.bsky.social & Manjusha Chintalapati. Excitedly, @arevsumer.bsky.social et al. in Nature today show similar timeline of N gene flow. Details👇
