Notes on a compelling discussion with @tsanglab.bsky.social
Genome = blueprint.
Immunome = real-time sensor.
The "curse of dimensionality" (millions of data points per sample!) meets AI compression.
Result? We can finally map the human immune system at scale.

Just saw a post which misspelled 'Machine learning' as 'Machine earning', and I wondered if that was a Freudian slip.

So important! Please contact your Republican senators, especially Sen. Susan Collins (R-ME), Sen. Shelley Moore Capito (R-WV), Sen. Bill Cassidy (R-LA), Sen. Katie Britt (R-AL), and Sen. Dave McCormick (R-PA). 🙏 amplify!
As Robert Kuttner writes, the NIH will need support from Republican Senators to avoid draconian cuts to its FY2026 budget.

Atul Butte’s talk introduced me to systems biology—I was presynapse scientist and opened my horizon to "biomedical moments, thawing frozen discoveries in data". Ideas that changed my career. Thank you for the science, the spirit, and the inspiration. You will be remembered.

Atul has been a constant inspiring force. He is perpetually optimistic and never stops to empower the world with more data and motivate all of us to dig deeper and be more innovative with data. I miss his energy and our conversations. RIP - May memories of Atul continue to inspire us all.
Atul Butte died yesterday.
The world lost a giant.
A big bear of a man.
With a huge smile.
With love for everyone.
With energy that could power a room.
I loved everything about Atul.
I loved how he was always happy.
I loved how excited he was about science and helping people.

I appreciate the offers from other scientists to help Harvard (students, labs, etc) through this attack, but what would be most helpful is for you to use your position to contact your elected representatives and make it clear this fight isn't just Harvard, it will affect you, and their districts too

All of NIH funding to Northwestern University is frozen. This pause includes noncompeting approved funding, new and competing grants with fundable scores. No reimbursements for money already spent have been received since March. This situation is rarely reported so please Please get the word out!

7/10 In a combined analysis of infants and previously sequenced adults (generated by @tsanglab.bsky.social lab; PMID:33713619), infants display a similar ISG signature in monocytes but a markedly enhanced ISG signature in T and B cells, which is consistent with infant specific immune features.

1/10 I am very excited to share our latest study, now out in @natcomms.nature.com. We applied a multidimensional approach to decipher the immune responses to SARS-CoV-2 infection in 2-month-old hospitalized infants. We analyzed: scRNA-of PBMCs, serum cytokines and antibody responses. rdcu.be/emkNa
