ACADEMIC BOYCOTT Israeli universities are major, willing and persistent accomplices in Israel’s regime of military occupation, settler-colonialism, apartheid, and now genocide.

A dysbiotic microbiome triggers TH17 cells to mediate oral mucosal immunopathology in mice and humans Combined patient and animal model studies implicate microbiota-triggered TH17 cells as disease drivers and therapeutic targets in periodontitis.

Would be interesting to see if this variant decreases susceptibility to periodontitis as well! check out this one ! www.science.org/doi/10.1126/... A dysbiotic microbiome triggers TH17 cells to mediate oral mucosal immunopathology in mice and humans | Science Translational Medicine

I am starting my lab at @ki.se and will be eventually opening PhD positions early 2026.
Gastrointestinal mucosal immunology and exocrine glands biology!

Impressive!

Excited to share a new chapter:
As of July 1st, I’ve joined @ki.se as an Assistant Professor and #NewPI!

The Monasterio Lab is officially up and running — we’ll study physiological circuits driving #salivaryglands and #GItract communication in health and disease.

Stay tuned for the science ahead!

I can’t unsee it

Lets not forget, all the below is 2ndary no matter how painful it may be. GAZA has no internet & still starved & massacred. lets not allow GENOCIDE GENOCIDE & FAMINE continue in darkness by the distractions of the horrifying Israeli policies #FreeGaza #StopGenocideInGaza #PeaceNow #BringThemHomeNow

A close-up of the star RIK 113, seen here surrounded by a cloud of gas and dust called a protoplanetary disc. These discs are a common feature around young stars, containing all the building blocks needed to make a new planet. Over time, these dusty discs will fragment and condense under the influence of gravity, forming larger objects like protoplanets. These planetary embryos carve out gaps in the dust around them, forming the intricate, ring-like structures that we can see in this disc.

New observations from the Very Large Telescope in Chile may have caught a Jupiter-like planet at its moment of birth around another star.

The xenacoelomorph gonopore is homologous to the bilaterian anus The bilaterian through gut with an anal opening is a key invention in animals, since it facilitates effective food processing, which allows animals to grow to a larger body size. However, because non-...

When and how did our “two-hole” digestive tube first appear in evolution? Such a fascinating question, recently tackled in this preprint!

“Our results suggest that the bilaterian anus evolved from a male gonopore that came in contact with the digestive endoderm to form the posterior opening.” 🧪

A huge shoutout to the incredible Anna Rudnitsky that led this project as a master student at the @weizmanninstitute.bsky.social. Many thanks to other lab members that contribute to this work, and to our collaborators and next-door neighbors @zivshulman.bsky.social /16

Incredible! Over the past 2 months, 5 independent manuscripts — from @TheColonnaLab, Dan Littman, @gardnerlabucsf.bsky.social and @chrysothemisbrown.bsky.social , and our own (now in @nature.com, www.nature.com/articles/s41...), reports that the dietary pTreg program is initiated by RORγt⁺ APCs. /1

It was amazing to do a Night Science workshop today at the Karolinska Institute in Stockholm!

Still buzzing after the Night Science workshop at KI — 6+ hours of creative thinking with @itaiyanai.bsky.social (#NightSciencepodcast)

Loved the deep dive into day science (structured, hypothesis-driven) vs night science (exploratory, intuitive). A brilliant way to rethink how we do science.

Amazing work!

Dear US researchers: break the outrage addiction. I survived the besieging of science. So can you As I watch US researchers respond to threats against science, I’m reminded of when scientists in Brazil navigated a similar storm.

EU's Von der Leyen announces 500 mln euro package to lure top researchers to Europe European Commission President Ursula von der Leyen announced on Monday a 500 million euros ($566.6 million) incentive package to boost European science research, as Europe hopes to lure top U.S. scientists disgruntled with President Donald Trump.

This is huge news!
