excited that this paper is finally out in @pnas.org : www.pnas.org/doi/10.1073/... Led by Gian Marco Visani (effort initiated by Michael Pun), fantastic collaboration with @pgtimmune.bsky.social @asya-minervina.bsky.social and Phil Bradley.

After many rewarding years at @StJudeResearch surrounded by exceptional colleagues & groundbreaking science, I’m delighted to join @fredhutch to push boundaries in viral & cancer immunology. Grateful to St. Jude and looking forward to what’s next at FH! More here: www.fredhutch.org/en/news/cent...

How much of the TCR repertoire can we make sense of? Can your TCR and GEX data be put in the context of other conditions/tissues? How many varieties of T cells are in the repertoire zoo? All these questions (& more) addressed in our latest preprint: MetaCoNGA www.biorxiv.org/content/10.1... . a 🧵

Eric Skaar presented this week's hospital-wide Danny Thomas Lecture, and it was a spectacular talk! So far outside what I normally think about and my mind was blown 🤯 Such innovative use of imaging modalities! THIS is why it is important for all of us to attend talks outside our usual science lanes🧪

Assessing CAR T cells cytotoxic capacity at the single-cell level can be tricky. Here we provide a method for encapsulating >500.000 single CAR T cells with single target cells in droplets together with reagents to examine killing using standard flow cytometry: app.jove.com/t/67657/drop...

I've got a new book extract in Wired! The book also has lots of stories about the history of controlled trials, case-control studies, cohort studies, confounding, causal inference and more - most of which I suspect you won't have heard before! You can order from: proof.kucharski.io

NEW: @motherjones.com reports that one of the men renditioned to El Salvador is Neri Alvarado, who was working in Dallas as a baker. An ICE agent told him they were questioning all men with tattoos. Neri has an AUTISM AWARENESS TATTOO in honor of his 15-year-old brother with autism.

Part of what’s good about this piece of writing is the clarity of thought, which is deceptively hard to achieve even when the language is otherwise stylistically impressive. Kevin was above all a clear thinker in an extraordinarily broad range of subjects. Even in disagreement he was worth reading.

I chatted with a program director at NIH for a half hour just now It's clear that the people who make American science happen are doing everything they can to keep making it happen in a very difficult environment They deserve our respect and gratitude

Please enjoy our paper showing that Lck- coreceptor association is important for repertoire diversity and lineage fidelity in T cells ☺️

I agree. It seems extremely unlikely that they are trying to get grants flowing again. One of my concerns is that they may be hoping to delay things enough that NIH will not have time to get appropriated funds issued by September 30th, the end of the fiscal year. 1/n

Word discovery of the day is ‘yoke-devil’ (17th century): an accomplice in a villainous or immoral undertaking.

We all owe @jeremymberg.bsky.social a debt of gratitude for his work in clarifying, connecting, and advocating for science in this chaotic time. 🙏🏼

HHS blocked posting indefinitely. Not enough press is being given to this back door approach to blocking NIH grants. If and when it is lifted will still be 35 days before study sections can be held

But many people were not new employees. They were long time employees who had recently been promoted because of their experience and good work, landing on probationary status (don’t ask me why the govt does this) purely because of their ‘good fortune’. Letting these folks go is stupid and cruel. /3

Amid the chaos over USAID funding and waivers, one thing is clear: PrEP (pre-exposure prophylaxis) for HIV prevention is not funded—unless you're pregnant or breastfeeding. 2025 could have marked the start of an HIV-free generation. 🧵

It seems like study sections for the Feb cycle are being pushed back until May. There will be a pile up of reviews in the “best” case scenario that something “normal” happens again. We will all need to step up & ad hoc our hearts out to help the SROs with the backlog (assuming things do get better)

If you worked in an HR department and fired a whole bunch of people to meet a quota, then realized you actually need these people to run the company, and then had to rehire the same people (which might be kind of difficult now), the next person the HR department should be firing is you.

“Defeating the Measles Demon”, by Utagawa Yoshifugi from 1862, when a massive measles outbreak hit Tokyo and killed thousands. As written in the description, the “wry humour [of these prints] encouraged social solidarity and gave hope and levity to people affected by the virus”. Link to info below.

A few people seem to be getting satisfaction from the fact that kids are getting seriously ill because their parents have refused to vaccinate them. I want to state for the record that I am 100% opposed to this type of thinking. These are kids. It was not their choice. They don’t deserve it.

Not exaggerating when I say that the path back is going to be built on people in positions of influence regaining their sense of self-respect. www.nytimes.com/live/2025/02...

#medsky #pedsky #IDsky #immunosky 🧪 I published this a bit more than a year ago. You should expect to hear a ton of falsities about measles in the coming days, mostly concentrated on purported benefits of the disease and the low severity. Here's why measles is best remembered as a monster:

Also because of the times in which we live- if you have ever had a question about the HPV vaccine, I probably covered it here (and if I haven't please ask me in the replies and I will do my best to answer or find someone who can answer) #medsky #pedsky #immunosky #episky #IDsky 🧪

I am deeply grateful to the extremely hard-working and dedicated staff at the NIH and NSF. Thank you to all of the Program Officers, Scientific Review Officers, Grants Management Specialists, and so many more, who have made the engine of US science and innovation run.
