Our Stem Cell Reports cover story titled, “GABA produced by multiple bone marrow cell types regulates hematopoietic stem and progenitor cells” is out today! doi.org/10.1016/j.st...

The Shutdown of U.S.A.I.D. Has Already Killed Hundreds of Thousands The short documentary “Rovina’s Choice” tells the story of what goes when aid goes.

The shutdown of USAID has already killed hundreds of thousands of people.

It was also the most effective soft power organization on planet earth helping American interests across the globe.

This was a powerfully foolish thing to do, inhuman and cruel.

Spatial dynamics of brain development and neuroinflammation - Nature A tri-omic atlas of the mouse brain from postnatal day 0 to P21 reveals that layer-specific projection neurons have a role in coordinating axonogenesis and myelination.

Our latest collaboration with @rongfan8.bsky.social, spatial triomics to investigate myelin and cortical brain development, and demyelination, spearheaded by Leslie Kirby in our lab @ki.se and Di Zhang in Rong's lab! Check it out @nature.com

Kmo restricts Salmonella in a whole organism infection model by promoting macrophage lysosomal acidification through kainate receptor antagonism Author summary Standard therapy for bacterial infections involves antibiotics to clear pathogens. However, the host immune system can also efficiently eliminate bacteria. We have recently shown that a...

Very happy to share the continuation of our discoveries on how the kynurenine pathway regulates innate immune responses during Salmonella infection. Congratulations to Emily Goering for leading this work and for starting her postdoctoral journey! 🥂👏🏻🍾

arXiv will no longer accept review articles and position papers unless they have been accepted at a journal or a conference and complete successful peer review.

This is due to being overwhelmed by a hundreds of AI generated papers a month.

Yet another open submission process killed by LLMs.

Gut–brain communication: types of sensory nerves and mechanisms of activation Nature Reviews Gastroenterology & Hepatology, Published online: 28 October 2025; doi:10.1038/s41575-025-01132-1This Review explores the different types of sensory nerves involved in gut–brain communication, detailing the locations of these nerve endings in the gut and their mechanisms of activation. Insights and new information regarding spinal and vagal afferents alongside viscerofugal neurons are detailed.

I love my lab so much 😭❤️🥹 feel so lucky

Hello Fly Folks. quick note FlyBase is under duress due to termination NIH$ to Harvard and intl collabs. The hardworking folks @flybase.bsky.social are doing their darndest to ensure access to current data. For US, there will soon be a new site to donate. Please spread the word, ideas and support 🪰💪

MIC-Drop-seq: Scalable single-cell phenotyping of mutant vertebrate embryos Pooled perturbation screens can reveal cellular regulatory networks, yet scaling these techniques for large-scale screens in animals remains challenging. To address this, we developed MIC-Drop-seq, wh...

To dissect the gene regulatory networks used to build organisms, we need Perturb-seq-like tools that work in whole animals.

For this purpose, we developed MIC-Drop-seq, a tool that couples high-throughput CRISPR in zebrafish embryos with single-cell RNAseq.

Medical Research Funding — Unbreaking How the administration is breaking the government, and what that means for all of us.

I urge everyone to read Unbreaking’s new page on everything the govt is doing to destroy & diminish medical research funding.

It’s the best thing I’ve read on this topic: @lizneeley.bsky.social & co have such done an incredible job.

Trump’s NIH And NSF Cuts Estimated To Cost The U.S. Economy $10 Billion Annually Economists find public R&D drives a quarter of U.S. productivity growth — and pays for itself

Trump’s proposed $23 billion in cuts to NIH & NSF could cost the U.S. economy at least $10 billion a year, according to new research. Public science funding drives innovation, productivity, and long-term growth. Slashing it isn’t saving money; it’s losing our future. www.forbes.com/sites/johndr...

My ongoing request:

If your NSF or NIH grant was terminated--whether at Harvard or elsewhere--please report it here.

NSF: grant-watch.us/submit-nsf.h...

NIH: grant-watch.us/submit-nih.h...

Our trackers are actively used in lawsuits and are often the only record that terminations ever occurred.
