🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!
We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵
Applications for our Next Generation Leaders program are open!
For 3 years, accepted early career scientists will join a supportive network and contribute to our research initiatives.
Apply by Mar. 31: https://bit.ly/3OjzdRa

The Sosa Lab is going to #SfN25 and actively recruiting ✨postdocs✨ with systems neuroscience experience! We study both fundamental memory processes and how memory changes during pregnancy and postpartum.
If you are interested in meeting at SfN, please email me! www.sosaneurolab.com/join/postdoc...
Thrilled to start my Group Leader adventure with these and other great scientists!
Thank you!
Candid photo of Zara Weinberg. She has short red hair, bangs and glasses. She is laughing.
The Leading Edge Fellows gathered this week to celebrate Zara Weinberg, a beloved member of our community. Our 7th cohort of Leading Edge Fellows (2026) will be named in her honor.
The Zara Weinberg Leading Edge Cohort application is now open! Due Feb 2.

Meet our 2025 cohort of Next Generation Leaders! For the next 3 years, they will network with other rising stars, participate in professional development, and share their ideas for future research directions.
I’m thrilled to share my postdoc work and the first paper from the McKinley Lab! 🎉

We built the first transgenic model of menstruation in mice.
We used it to uncover how the endometrium organizes and sheds during menstruation. 🧪

Today in @nature.com, we present our work leveraging functional genomics and human blastoids to uncover a human-specific mechanism in preimplantation development driven by the endogenous retrovirus HERVK.
Special thanks to the reviewers whose comments improved our manuscript a lot! rdcu.be/eI3tD

We will be seeking a postdoctoral researcher to join the growing team! If you are a rodent neuroscientist and interested in doing systems neuro work in the mountains 🏔️, please check out the "Join" page.
I'm excited to share that I've started my lab @stanford.edu in the Neurobiology Department! neurobiology.stanford.edu/who-we-are/f...

Very cool, congrats!
1) I am delighted to present this terrific tour de force research conducted by my post-doc Dr. Gayani Senevirathne @gayani.bsky.social and published today in Nature -

Extremely excited to share that I’m joining Columbia University @columbiauniversity.bsky.social as an Assistant Professor!
We will explore how the mobile genome works—how transposons shape us, our DNA and how they can be harnessed to build useful technologies. #NewPI #RNAsky #TEsky

Thanks for featuring my new lab @thetransmitter.bsky.social!
Diet/microbes place the gut epithelium as a nexus for evolutionary change. With Jason Spence and Craig Lowe labs we use #organoids to explore how evolution prepared the developing human intestine for exposure to the environment. @science.org #evodevo www.science.org/doi/10.1126/... 1/11
Congrats!! 🎉 🎉 🎉
A chart showing cancelled NIH grants
“I would like to cure brain cancer. I think that's not particularly controversial.” Be that as it may, the NIH terminated that scientist's grant. Here's a huge survey of the 2,500 grants that NIH has killed or delayed...so far. Gift link: nyti.ms/43Jz1yJ

Postdoc position in human brain evolution at the amazing @janetsong.bsky.social lab at Harvard! Despite the freeze, she’s hiring! Send her a message.
Thrilled to share our latest study out in @natureportfolio.nature.com led by the fantastically talented Jing Liu. Our study provides insight into a long standing question in biology: What molecular features make us uniquely human and how do these function? www.nature.com/articles/s41...
Today in @nature.com , we report a spatial single-cell atlas of human cortical development, revealing surprisingly early specification of human cortical layers and areas.
We built an interactive browser to explore the spatial data: walshlab.org/research/cor...

I am thrilled to share our preprint where we take advantage of the unique opportunities offered by human blastoids to uncover a human-specific mechanism potentially playing a role in preimplantation 🧵. www.biorxiv.org/content/10.1...
Woohoo, congratulations!! 🎉
A phylogeny of the 7 ape genomes that have now been completed from "T2T", with Homer Simpson representing mankind.
A project five years in the making, we've now published complete "T2T" genomes for six additional ape species! It turns out that finishing (and analyzing) six genomes is slightly more work than one... doi.org/10.1038/s415...
Compelling evidence that the activity-dependent gene expression program has changed between human and chimpanzee neurons (new preprint by @janetsong.bsky.social and collaborators) 🧪🧬🧠
www.biorxiv.org/content/10.1...
Fascinating new work by @janetsong.bsky.social and colleagues on species-specific neural gene regulation, using human-chimpanzee tetraploid cells 🧪🧬🧫🧠
www.biorxiv.org/content/10.1...
These preprints result from a close collaboration with Ava Carter, who is on the job market this year --- hire her!!! And a huge thanks to our postdoc mentors, Chris Walsh and Mike Greenberg, for supporting these projects!
We show that regulatory changes in neural progenitors affect neurogenesis-related gene programs and that regulatory changes in excitatory neurons affect synaptic gene expression and neuronal firing.
