Looking forward to it!
On September 9th Ashley St. John from Duke-NUS (@StJohnLab) will give a Semmelweis Seminar with the title 'Flavivirus immune history as a determinant of future viral infection outcomes'. 2pm at the Jugendstilhörsaal of @MedUni_Wien

Day 2 of @SgSI_Immunology Annual Symposium ended on a high note with @EvNewell1 sharing exciting updates on his work since leaving Singapore. Great #science and #friendship are the best combination for our thriving community. Looking forward to meeting again next year! – at Singapore

An analysis of skin and blood after #dengue infection in @ScienceAdvances shows a more dramatic reshaping and enrichment of T cells in the skin, indicating that vaccinations bolstering the skin’s immune response could help protect against dengue infection. scim.ag/4drlIcP

A new @SciImmunology Review discusses the lessons learned from Zika virus infection research, including maternal-fetal immune crosstalk and potential strategies for therapeutic targeting. scim.ag/3NCWQUC

Approximately 10 years after the discovery that #Zika virus infections cause #congenital defects, a new Science #Immunology Review examines how experimental models have shed light on the mechanisms driving disease outcomes. @StJohnLab @dukenus scim.ag/4uD5lzN
We wanted to put over a decade of advances on the immunology surrounding fetal Zika infection in context in our review "Immune mechanisms of congenital Zika syndrome" @SciImmunology. So happy to see it's #openaccess! written with @Abhay_R_ science.org/doi/10.1126/scii…

The @aller_gyimm was officially opened today. The result of a journey which began a long time ago. It really transforms our ability to do research.
So thankful to our whole family @aller_gyimm and @chandi2012 for making this happen.
Exciting times ahead!

Analysis of data from nearly 1.5 million Danish children suggests that infants hospitalized for #RSV infections have a significantly higher risk of developing asthma when one or both parents are also asthmatic. @bart_lambrecht @BosteelsCedric

Very inspired that Yaghi, a Palestinian refugee who came to the U.S. at 15 received the 2025 chemistry #NobelPrize . A reminder of the power of education to unleash talent, a testament to U.S. capacity to attract/ enable talent, and how much progress a we lose to incessant wars
This year’s chemistry laureate Omar Yaghi was born in Amman, Jordan, in 1965 to parents who were refugees from Palestine. When we spoke to him he shared his story:
“I grew up in a very humble home, we were a dozen of us in one room, sharing it with the cattle that we used to raise. I was born in a family of refugees, and my parents could barely read or write. My father finished sixth grade and my mother couldn’t read or write. It’s quite a journey. Science allows you to do it. Science is the greatest equalising force in the world.
Smart people, talented people, skilled people exist everywhere. That’s why we really should focus on unleashing their potential through providing them with opportunity.”
Today Yaghi shared the 2025 Nobel Prize in Chemistry with Susumu Kitagawa and Richard Robson for their work developing metal–organic frameworks.

Delighted to see Chia-Lin featured by @JExpMed - one of the #womeninSTEM I’ve always admired.
👩🔬 JEM invited NYCU’s Prof. Chia-Lin Hsu to share her journey as a female scientist—founding a lab, chasing dreams, and overcoming challenges.
A voice from Taiwan to empower more women in science. 💡

The Granulocyte Meeting 2025 has officially concluded!
🙏 Huge thanks to all the incredible speakers & chairs, your contributions made this meeting a success.
📍 Looking ahead: see you all at #GMeeting2027 in Korea! #GMeeting2025

“I was fired for holding the line on scientific integrity. The stakes are not theoretical — we have already seen the largest [US] measles outbreak in more than 30 years, which claimed the lives of two children.”
