The US President's new proposal to tax international students has been approved by the White House for release this week. It's an unprecedented $100,000 tax on int'l grads who stay to work after graduation on Optional Practical Training (most grads do), a crucial bridge to remaining by any channel.

NIH funded peeps: This is insane and coming for us.
For FY 2026 RPPRs:
If there are any publications with a foreign co-author, a statement submitted through the Signing Official (SO) confirming the author will no longer publish or collaborate with the foreign partner is sufficient to show the collaboration has ended. Also indicate that no IDeA money was transferred via subcontract to an institution in a foreign country. This path will minimize delays.For FY2027 RPPRs onward:
Pls are required to submit prior approval requests for any publication co-authored with individual(s) affiliated with a foreign institution(s).
Per NOT-OD-26-026, prior approval requests must be initiated and submitted by a SO for the recipient organization.
In addition to noting the foreign site and the name of the foreign investigator, the prior approval request should provide information about the nature of the research being conducted; why the involvement of the foreign site is necessary; and whether any data will be transferred.

If their goal is to choke off economic advantages from the US’s university system it’s hard to think of a more effective way. Scientists and other academics come to the US to study— then stay in the US often via green cards, to start companies, do unique work, and contribute to the US economy.

It’s brutal in academia right now. A lot is out of our control, but it doesn’t cost anything to remember that there are humans behind papers and grants…reviewers, program officials and funders can be more empathetic in the face of unprecedented chaos in the US scientific enterprise.

before I started my lab, I asked several senior PIs what their one piece of advice would be and PI pointedly said: “Know when to drop a project.” And that advice has been invaluable in my lab. There are always other projects to follow up on, dropping one isn’t a failure in and of itself.

An essential development over the past decade-plus is that the ignorant went from feeling chastened when their ignorance was revealed to banding together and deciding that, actually, they were right. They might disagree at times, but they agreed that ignorance itself was an indicator of trust.

I agree what matters is how funding priorities are set, and by whom. Institute directors must be hired based on expertise/ experience, not partisan politics, or funding priorities AND DECISIONS will reflect ideology. The system already allows this, but one can read intention into making this easier

And I’m a big fan of Turing, von Neumann, Shannon, Metcalfe, Hinton, Sejnowski, and all the other algorithmic and computation people. No shade. But data limits still limit understanding of the brain. That’s why the #NIH US BRAIN Init was so important: public investment made new tools.

Same for neuroscience. The lack of ability to measure many neurons’ activity, perturb them, and measure intracellular processes and connections is what limits understanding the brain. The key barriers are not algorithms or AI. 🧪#neuroscience 🧠🤖 #MLSky
Anshul Kundaje @anshulkundaje
Francois usually has good takes. But this suggests a bit of cluelessness about what the key barrier to progress in biology is. It's not algorithms or Al. It's still a lack of the ability to measure many important things in cells ie. assay techdev. Perturb-seq is not all u need.

Intriguing new insights on axonal TDP-43 in ALS from @labperlson.bsky.social and colleagues www.nature.com/articles/s41...
nature.com
Muscle-derived miR-126 regulates TDP-43 axonal local synthesis and NMJ integrity in ALS models - Nature Neuroscience
Ionescu, Ankol et al. show that, in ALS mouse and iPSC models, TDP-43 aggregation at NMJs stems from aberrant axonal translation, normally repressed by muscle EV-derived miR126. Loss of miR126 in ALS increases TDP-43 buildup, impairs local synthesis and triggers degeneration.
