🚨🚨I’m excited to present our lab’s new paper where we tried to provide a mechanistic explanation for the link between antibiotic use and risk of developing inflammatory bowel diseases (#IBD). A 🧵/1 https://t.co/k2wUPoIwTm

Antibiotics inhibit production of the protective mucus in the colon, thus predisposing to gut inflammation.

Antibiotics also anti-you? Antibiotics have been wondrous drugs for humanity—saving millions or perhaps billions of lives and decreasing much human misery. However, they are promiscuously prescribed and often by doctors who give little or no thought to whether they may be

The arms race between bacteria and bacteriophages (phages) gave rise to multiple layers of antagonistic mechanisms, many of which remain unexplored. Here, we investigated the anti-phage defense...

We are not our government. Today hundreds of thousands of Israelis, including academics and presidents of all major universities in Israel, went on strike calling to seal the deal to bring our hostages back and end the war now!!

This is one of the coolest stories I've seen. Fight the virus to clear the fungus.
🚨 Fungi + viruses + mammalian lungs? Buckle up! Our new paper in @natmicrobiol.nature.com uncovers the story of a deadly fungus and its gnarly viral hitchhiker — and how this duo may change how we diagnose & treat fungal disease 🍄🫁🚨 https://t.co/Y9GPa76GrU ⬇️

A huge milestone for the lab, and for me personally 💪Thank you Israel Science Foundation #ISF for supporting our research on #nocebo effects in everyday life. We'll examine how health perceptions can causally shape physical health outcomes, and study the mechanisms involved.
Congrats to our #ISF 2025–2026 grant recipients from the @Bar_ilan Azrieli faculty of medicine: Dr. @LironRozenkrant is exploring how subjective health perceptions impact physical health; Prof. David Karasik is studying early bone development to prevent osteoporosis later in

Some personal news: I was promoted to Full Professor at @UChicago. This milestone is deeply meaningful and also feels quite surreal. When I started as a grad student at UChicago in 2005 I never imagined my journey would lead me here 20 years later as a professor

1/4 I am saddened of the passing of my former Ph.D. mentor, Prof. Zelig Eshhar, earlier this week. Zelig pioneered the development of CAR-T therapy (which he dubbed “the T body approach”) decades before immunotherapy became a hallmark of cancer treatment. In recent years, he...
