Postdoc position open in the lab, build a really cool tool to determine how immune cells migrate to and from various organs! Please share job-boards.greenhouse.io/biohub/jobs/...

Wait! I didn’t look closely enough- the equally amazing Will Foster is also tucked in the back! Extremely proud of my team members representing the lab at my fave meeting while I’m at home with 👶🏼

Proud to mentor the fantastic Gaby Berman as part of this amazing line up!

Today in @nature.com, the @christophthaiss.bsky.social & @maayanlevy.bsky.social labs trace age-related memory loss to the gastrointestinal tract & map the complete gut-to-brain pathway driving it. Targeting this pathway can reverse cognitive aging in mice. www.nature.com/articles/s41...

My latest 'pinch yourself' moment from the Lab. We previewed two really really exciting papers from the Eisenbarth and Pabst Labs for @cp-immunity.bsky.social Read our summary here> www.cell.com/immunity/ful... A big well done to Gaby Berman in my group and authors of both excellent manuscripts!

Absolutely thrilled to put this into the world-first Nowosad Lab preprint is live 🥲 Check out what me and @thelundlab.bsky.social get up to when left to our own devices. Full breakdown to come, but for now let us know what you think. @nyulangone.bsky.social www.biorxiv.org/content/10.1... #immunosky

Taxpayers should not accept cuts in funding for cancer research. Bravo 👏🏾👏🏾👏🏾👏🏾👏🏾 @miriammerad.bsky.social 👇🏼👇🏼👇🏼Sign up to show New York State law makers that you want your tax dollars to fund life saving research www.nycures.org

Leaving Basel after an amazing @embo.org meeting on Barrier Immunity! Bravo @maurogaya.bsky.social and @immunologyking.bsky.social for putting together such a brilliant lineup.

Great analogy to illustrate the question @carlanowosad.bsky.social is pursuing on her lab: how GC are form and how GC cells find their way to their specific locations #embo workshop Basel #immunalogy

Fantastic @embo.org young investigator lecture on lung B cell responses from @maurogaya.bsky.social #EMBObarrierTissues

Why does selection feel so weak relative to mutation in affinity maturation? A new blog post giving three perspectives, including our new transformer-based model of natural selection on antibodies: matsen.group/general/202...

Love this series! Great to see some familiar faces in here 😎

🧪 Senate appropriators say: NIH's budget gets a... boost! Rather than 40% cut, NIH gets a $400M *increase* in the Senate committee bill for FY26 (about +1%). "Congress has your back," said @murray.senate.gov. ADVOCACY MATTERS! There's still a long road (esp in the House), so keep up pressure.

BREAKING: Trump wants to illegally cut off $15 billion in lifesaving NIH research. Research to cure cancer, Alzheimer's, and so much more is on the line. These people are LYING about waste, fraud, and abuse at NIH to justify attacking medical research—we all need to say so. My full statement. ⬇️

Starting up OnlyLabs, where people can pay to watch researchers who used to have federal funding do Hot Uncensored Cutting Edge science experiments.

Nowosad Lab will be recruiting postdocs soon. Reach out if you are interested!

S1P is produced in the outer lymph follicle area and degraded by B cells resulting in a negative gradient towards to follicle center. S1PR2 signalling on GC B cells leads to migration arrest, keeping B cells within the follicle. (🐭 data) Green et al 2011 🧪⑂ www.nature.com/articles/ni....

'Under the new administration, the NIH, which for more than 75 years has supported scientists who are pursuing research deemed to be in our national interest, is pulling back. Budgets are being slashed.'

Big day for the lab today 🧪

Congrats to Gaby Berman, officially a Nowosad Lab PhD candidate!!

Please share this widely and encourage students to apply! Many of our current graduate students were recruited through this program -- happy to answer any questions and connect with students bsky.app/profile/stan...

Cream puffs in a tip box can only mean one thing… a celebration! Nowosad Lab milestone- first student qualifying exam complete 🥲

The astounding contribution of US academic science to new medicines www.statnews.com/2025/06/06/u...

NEW: Important Context spoke with a dozen people working at NIH about Director Jay Bhattacharya. The descriptions were universally unflattering, painting the health economist as ineffectual, dishonest, ideological, arrogant, and uncommitted to science. www.importantcontext.news/p/out-of-his...

The bottom line with the proposed cuts to NSF is to cut the number of working scientists and disappear opportunities to train new scientists. This is a PROPOSED budget to Congress. Call your reps.

Presidential budget proposes a 70% reduction in NSF funding for 2026 compared to2024. Instead of funding 23% of proposals (2024) they will fund 7% (2026). A perfect recipe for the destruction of American science.

Not one, not two .... but FIVE recent papers highlighting a role for RORgt+ antigen-presenting cells in the gut in establishing tolerance to food antigens #oraltolerance #immunosky #foodallergy

Last chance TODAY - to register and submit abstracts for #EMBObarrierTissues in Basel 🇨🇭🇨🇭🇨🇭! We've hit our registration goal 🥳, but there's always room for more.

Had the most fabulous day at Stanford today. Thanks all for coming to my seminar and being so interactive!

Fantastic talk from @carlanowosad.bsky.social on B cells and clonal selection - so much cool data! 🤩
