A master class from MIT in responding to authoritarian overreach:

Your “premise … is inconsistent with our core belief that scientific funding should be based on scientific merit alone.
… America’s leadership in science & innovation depends on independent thinking & open competition for excellence.
Dear Madam Secretary,
I write in response to your letter of October 1, inviting MIT to review a "Compact for Academic Excellence in Higher Education." I acknowledge the vital importance of these matters.
I appreciated the chance to meet with you earlier this year to discuss the priorities we share for American higher education.
As we discussed, the Institute's mission of service to the nation directs us to advance knowledge, educate students and bring knowledge to bear on the world's great challenges.
We do that in line with a clear set of values, with excellence above all. Some practical examples:
• MIT prides itself on rewarding merit. Students, faculty and staff succeed here based on the strength of their talent, ideas and hard work. For instance, the Institute was the first to reinstate the SAT/ACT requirement after the pandemic. And MIT has never had legacy preferences in admissions.
• MIT opens its doors to the most talented students regardless of their family's finances. Admissions are need-blind. Incoming undergraduates whose families earn less than $200,000 a year pay no tuition. Nearly 88% of our last graduating class left MIT with no debt for their education. We make a wealth of free courses and low-cost certificates available to any American with an internet connection. Of the undergraduate degrees we award, 94% are in STEM fields. And in service to the nation, we cap enrollment of international undergraduates at roughly 10%.

source: 
https://orgchart.mit.edu/letters/regarding-compact • We value free expression, as clearly described in the MIT Statement on Freedom of Expression and Academic Freedom. We must hear facts and opinions we don't like - and engage respectfully with those with whom we disagree.
These values and other MIT practices meet or exceed many standards outlined in the document you sent. We freely choose these values because they're right, and we live by them because they support our mission - work of immense value to the prosperity, competitiveness, health and security of the United States. And of course, MIT abides by the law.
The document also includes principles with which we disagree, including those that would restrict freedom of expression and our independence as an institution. And fundamentally, the premise of the document is inconsistent with our core belief that scientific funding should be based on scientific merit alone.
In our view, America's leadership in science and innovation depends on independent thinking and open competition for excellence. In that free marketplace of ideas, the people of MIT gladly compete with the very best, without preferences. Therefore, with respect, we cannot support the proposed approach to addressing the issues facing higher education.
As you know, MIT's record of service to the nation is long and enduring. Eight decades ago, MIT leaders helped invent a scientific partnership between America's research universities and the U.S. government that has delivered extraordinary benefits for the American people. We continue to believe in the power of this partnership to serve the nation.
Sincerely,
Sally Kornbluth

Every targeted institution (my own very much included) should cut and paste this letter onto their letterhead.

15 years in the making, we confirmed that mitochondria - the powerhouse of the cell - have an unusual localization in patients who experience psychosis (including schizophrenia and bipolar disorders). You’ll never guess what kind of patient cells we used to make this discovery… 🧵
mitochondria from bipolar patients are closer to the nucleus in these images; control patients' are spread out further

Liberals say that recent Supreme Court ruling have given the executive branch too much power. But they’re wrong, because the rulings only apply to Trump and will all be reversed when there’s a Democratic president.

Johns Hopkins sophomore student Florin Selaru develops a new scheme to deconvolve colors in histological sections for digital pathology.

It greatly outperforms traditional linear color deconvolution.

Congrats Florin!

If you’re applying to your dream lab for an internship/PhD/postdoc, always send a second email 1-2 weeks after the first one if you don’t hear back.

I promise we will be grateful rather than annoyed. My email inbox is a disaster and I’m quite junior - and very few of us have secretarial support

A lot of people think that every international student admitted means one fewer spot for domestic students, when the opposite is more likely true - the tuition revenue international students bring allows public universities to provide substantial discounts to domestic students, improving access.

Has America become so soft and woke that we can't appreciate why all of our top generals need to leave their posts and fly to Virginia to be lectured by the Fox News weekend host about the warrior mentality?

Pleased to update this - The paper is published in Cell Reports!
A long road for this one, the paper grew exponentially and evolved over a couple of years. Thanks to @makris1.bsky.social for sticking with it to untangle all the new data!

Quinnipiac in recent poll asked: Do you think that the way people talk about politics these days is contributing to violence in the United States, or don't you think so? 82% of voters agreed with this including majority of Dems, Independents, and GOP. I said basically this and got fired.

"our analysis indicates that substantial NIH budget cuts—including those implemented at the funding margin—could curtail research linked to a large share of potential drug approvals."

The word “autism” was first used to describe behavioral differences in children in 1911 but autism has been documented using available records going back to the 1700s (definitively) and further.

Acetaminophen (Tylenol, paracetamol) was discovered in 1878 and first sold in the United States in 1950.
