Thrilled to share our new paper, out now in @natneuro.nature.com, uncovering how estradiol, the most potent estrogen, modulates reinforcement learning and reward prediction errors across biological levels. www.nature.com/articles/s41... #blueprint 1/7

A “promise of a vote” is no better than a “concept of a plan”

This White House made a choice to pay ICE instead of SNAP and ATC - we could just as easily be flying just fine and feeding people instead of harassing them. Don't cave now

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...

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. www.leadingedgesymposium.org/apply/

Applications are open for the 2026 Zara Weinberg cohort of Leading Edge, named in honor of the incredible, brilliant, fearless @weinberz.witchlab.org. The LE community has been truly transformative for my scientific journey and my happiness. Please apply!! www.leadingedgesymposium.org/apply/

I have been blown away by the level of support (both practical and emotional support!) from the #LeadingEdge community. I feel so grateful to be a part of this group. Consider applying!! www.leadingedgesymposium.org/apply/

Zara Weinberg passed away earlier this week. She joined my lab earlier this year when her postdoc lab formally closed. She was a brilliant scientist, supportive mentor, dear friend, avid music fan, rabid believer in public transit, open science champion, and above all just an amazing human.

Hi everyone! We are taking a look at the state of funding in the neuroscience field so we are looking for PIs to answer this survey. Please feel free to fill out and share with colleagues. Ty!

The Sosa Lab website is now live! www.sosaneurolab.com 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.

New preprint alert! The uterus expands ~500-fold in pregnancy, yet we know little about how pressures are sensed. Led by @yunxiao-dr.bsky.social, we show PIEZOs are required for contractions and birth in mice, with dual roles of PIEZO1 in muscle and PIEZO2 in neurons www.biorxiv.org/content/10.1...

Great news for science and for Stanford!! Laura’s research is amazing! 🤩

The proposed budget slashes NIH by ~40%, devastating medical research, clinical trials, treatment breakthroughs—life-saving work. Thousands of lives at risk for tax cuts for the rich? NO THANKS. Tell your senators to oppose the cuts HERE: zurl.co/qiKdX zurl.co/RCR0y #CutsCostLives

Great piece from @thetransmitter.bsky.social about the field’s current understanding of the hippocampus! Honored for the nod to our recent paper among these many other excellent studies www.thetransmitter.org/memory/expan...

I spoke with Jade Hindmon, host of @kpbssandiego.bsky.social Midday Edition, about the consequences of the current administration’s cuts to science funding. Please share to help spread the word and raise awareness. www.kpbs.org/podcasts/kpb...

Add your name to our open letter condemning Trump’s latest Executive Order that appoints politicians — not scientists — to evaluate research. Take action now! actionnetwork.org/petitions/op...

After ruling the NIH grant cuts were illegal yesterday, Judge Young, a Reagan appointee on the bench since 1985, ended the hearing with a blistering 15-minute speech. I've cleaned up my notes — here are his remarks in full. 🧵

Neuroscience research and training has taken a $323 million hit in the form of grants rescinded by the U.S. NIH, according to an analysis by @thetransmitter.bsky.social. By @claudia-lopez.bsky.social #neuroskyence www.thetransmitter.org/funding/nih-...

It's officially published!! In my main postdoc work with @markplitt.bsky.social and @lgiocomo.bsky.social, we found that the hippocampus simultaneously encodes an animal's spatial position and its experience relative to reward in parallel population codes. 🧵 www.nature.com/articles/s41...

New paper from the lab officially out! Congratulations @marisosa.bsky.social - amazing work - and just before she sets off to UC Boulder to start her own lab!

Many thanks to @stanfordbrain.bsky.social for this beautifully written feature of our latest work!!

Has anyone successfully tried to submit Form ITA-338P to request a tariff exemption for scientific instruments for nonprofit use? www.trade.gov/sites/defaul...

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. unbreaking.org/issues/medic...

We're suing the Trump administration over its politically-motivated termination of research grants that has already harmed scientists and our communities. Political ideology shouldn't dictate public health.

1. It's Fustilarian Friday and today's drop is the "Restoring Gold Standard Science" executive order. My read is that this is designed to (1) protect far-fringe figures such as the antvaxxers now heading our health agencies, and (2) kneecap efforts to use scientific evidence in regulatory policy.

🚨Hiding under 6 sections of science sounding rhetoric is an edict to appoint officers at each agency that will be responsible for detecting research that isn't "Gold Standard Science" as defined by the White House🚨 Stay tuned for rapid response action! www.whitehouse.gov/presidential...

Our R01 was part of yesterday's "mass termination" at Harvard; 1 of ~1000 NIH grants in Trump's "fight". The irony of how many Jewish (& non-Jewish) researchers/scientists/physicians/patients/students will be harmed in the name of "fighting antisemitism" is sickening.deliberately cruel. #AcademicSky

This is extremely disappointing. My heart breaks for all of the scholars that spent so much time and energy on this.

Yesterday, the NIH R35 “Outstanding Investigator” grant to fund scientists in my lab studying antibiotic resistance was terminated for reasons not related to the content of the science, or any actions taken by me or members of my lab

New lab alert!! Mari is an incredibly creative and awesome scientist - plus an amazing mentor! If you have the opportunity to join her lab - I can’t recommend it enough - can’t wait to see her get started ❤️

Exciting news!! I’m joining the tenure-track faculty at University of Colorado Boulder this fall as an Assistant Professor of Psychology & Neuroscience! The Sosa Lab will study how memory is shaped by cognitive and physiological demands, including during pregnancy and the postpartum period. 🧵

ACTION ITEM-----ACTION ITEM Implementation of Schedule F This is what a lot of us have been worried about. This allows for many civil service positions to replaced with political appointees. This could include NIH institute directors and even POs. BUT THERE IS A COMMENT PERIOD... 1/n

I've already had two federal grants terminated and face a 33% pay cut due to future terminations. It's painful, but not as painful as the conversations I'm having every day with brilliant trainees in graduate school and postdoctoral positions who see little future for themselves in US science.

This is so not okay.

Super exciting work from @oliolabs.bsky.social! Efforts like these are so important to improve treatment outcomes for women.

First and foremost, an incredible THANK YOU to everyone who has supported Stand Up for Science—whether you attended our events, donated, shared, or volunteered. We are so humbled by how many people showed up to support us & all of the passion that people brought with them.

Whenever you hear someone sneer about scientific research that seems useless to them — “they’re studying the spit of lizards?!” — remind them that’s exactly how we got Ozempic. globalnews.ca/news/9793403...

It's time to educate our neighbors about the importance of science funding. Local news papers still exist and are read by folks. Here is the op-ed I wrote for this week's "News of Orange", a local paper in Orange Co NC. Full text is on the alt-text 🧪

Anyone know why Pubmed/NCBI is experiencing such heavy traffic on a late Thursday evening? 👀

@neuronline.sfn.org has made it incredibly easy to contact your reps and urge them to protect federal funding for biomedical research! Please sign today, it takes about 10 seconds: www.sfn.org/Advocacy/Adv...

NSF FUNDING FREEZE UPDATE I received this email from the NSF about 45 minutes ago. Attached are the links. I believe this should restore trainee funding but await confirmation on that. nsf-gov-resources.nsf.gov/files/TRO-NY... new.nsf.gov/executive-or...

Grateful to @avaskham.bsky.social and @claudia-lopez.bsky.social for getting the word out about this alarming attack on NIH funding and programs to support diverse early career researchers.

“The NIH communications pause feels like a part of a bigger shift and attack on sciences because there is a suspicion about our work or who is selected to do this when it is in fact very competitive and benefits society as a whole.”
