    Very sad to hear that UMass is rescinding all PhD admissions for Fall 2025. This means there will be no new PhD cohort, and UMass will not have a graduating class that year. This is just unprecedented and I am so very sorry for all the affected students.

    This is incorrect. UMass is NOT rescinding all PhD admissions for Fall 2025. Only the Morningside Graduate School has done this. Other UMass programs have not. Read here for details: masslive.com/worcester/2025… “applicants to UMass other graduate schools …. are not impacted” boston.com/news/health/20…

    Beautiful picture with all my fellows’ babies born in the lab recently and one on the way ! Scientists don’t hesitate to have kids if you want one ! parenthood often increases productivity, focus and happiness !

    25 years ago, I came to Stanford on a J1 visa and worked so hard to be worthy of that privilege. Today, I lead Immunology at Mount Sinai and I am the one who feel privileged when brilliant international students chose to join us.

    One family spent their entire vacation budget on these tests. On my way back I saw that in Paris’ airport, antigen tests were free! Antigen tests cost max 15$! @JFKairport should forbid test centers that make disgraceful profits out of people misfortune!

    Excited to share our new paper in @NatImmunol on how TREM2+ monocyte-derived macrophages in lung cancer reduce activity of natural killer cells that fight tumors. We provide potential dual targeting strategies to improve antitumor immunity. Read here: rdcu.be/damS8

    Our paper on the effect of fasting on innate immunity was published today alongside a beautiful study on the role of fasting on memory T cells by my very close friend and compatriote Yasmine Belkaid ! hate chauvinism but a bit happier than usual today !

    We started a large effort to review all COVID19 studies posted BioRxiv. Our goal help highlight relevant new data . Trainees screen and write short reviews and faculty review and post on BioRxiv. Thank you very much Sinai Immunol for the effort. @SinaiImmunol #COVID19

    Given the accumulation of #COVID19 literature posted in preprint servers, we have started an institutional effort to provide critical reviews on articles posted on @biorxivpreprint and @medrxivpreprint. Direct links to these reviews will be updated in this thread ⬇️

    Immunology takes center stage again at the #NobelPrize! Congratulations to Mary Brunkow, Fred Ramsdell & Shimon Sakaguchi for uncovering how regulatory T cells maintain immune tolerance—a discovery that transformed our understanding of autoimmunity and cancer immunotherapy

    I travelled this week to paris from @JFKairport . @Delta did not ask for vaccine passports but I saw several families in tears because they were forced to get an antigen test before boarding regardless of vaccine history-cost of the tests were 200$ per person ( adult& kids)
