Congrats to the Brown Lab!! Great fundamental question to tackle!, and I’m sure many fascinating discoveries to come!!

A wave of Thetis cells imparts tolerance to food antigens early in life Within the intestine, peripherally-induced regulatory T (pTreg) cells play an essential role in suppressing inflammatory responses to food proteins. However, the identity of antigen-presenting cells (...

Excited to share our study describing a role for a subset of Thetis cells, TC IV, in tolerance to food antigens. A team effort led by Vanja Cabric and Yollanda Parisotto

'I did not complete a customs declaration for frog embryos (...) this would normally result in a warning or fine. Instead, my visa was revoked & I was sent to a detention center in Louisiana, where I have spent the past 3 months with roughly 100 other women. We share one room w dormitory-style beds'

Just deranged. This was a *solved* problem.

Published an op-ed for @cnn.com: “Nobel laureate: I owe America my success. Today, its scientific future is in danger.”
A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world.

-- Senator Cory Booker, today

Thank you, Cory Booker for defending scientific research. Speaking out against the mindless, tragic loss of economic benefit, our global scientific competitive edge and hope for so many families in health crises so clearly after standing there for 24 hrs is remarkable.

People/organizations with means and a vision for the future of biomedical science - we need an “Arc Institute” equivalent in the DMV area to sponge up all the incredible talent, opportunity of a lifetime for a visionary entrepreneur, I will help! @mcuban.bsky.social

1. For the past thirty years I've had the best job in the world.


I've had the opportunity to follow my curiosity; explore the workings of nature and society; mentor students and junior colleagues in the same process; and teach generations of students about it all.

Opinion | DOGE Needs a Different Playbook for Science We need less administrative bloat in science.

‘If a VC firm measured efficiency purely by how little money it spent, rather than by the returns it generated, it wouldn’t last long. We invest in scientific research because we want returns — in knowledge, in lifesaving drugs, in technological capability.’

Opinion | We Were Badly Misled About Covid (Gift Article) The same dangerous mistakes. The same lack of candor.

Well worth a read. Not because of the content - it's total horseshit - but because it's a prime example of what happens when you mix anti-science, conspiracism, arrogance, and a total lack of expertise.

Maybe one day NYT OpEds will engage with the actual science 🤷‍♂️.
