In case you want to take a break from ~everything else going on~ to read a lil bit about causal mediation analysis, sample selection bias, and disparities in liver transplantation decisions... here's a new paper: arxiv.org/abs/2509.01969
Mediation Analysis in the Presence of Sample Selection Bias with an Application to Disparities in Liver Transplantation Listing
The study of disparities in the liver transplantation process may focus on quantifying causal effects, particularly the average, direct, or indirect effects of various social determinants of health on...

This paper I contributed to may be of interest to both public health folks and philosophers of science — we outline a view of how to understand and operationalize “intrinsic health” as distinct from “no disease”

(ffo of words like “emergence” and “operationalize”)
cusciofhealth.bsky.social Science of Health at Columbia University @cusciofhealth.bsky.social · Jun 23
Complex systems theory meets evolutionary biology in our new paper on 'intrinsic health.' We propose a first-principles approach to understanding health as an emergent property with measurable dynamics.

A powerful piece by Daniel Malinsky on why scientists must resist Trump’s authoritarian agenda:

“In these times … scientists have a duty to dissent.”

🚨 A new rule would let career scientists like NSF/NIH program officers be replaced by political appointees

Already 14,000+ public comments, deadline is Friday

📣 Comments can be short. Courts consider them—and scientists with NSF/NIH experience are especially impactful

OpenAI's "most powerful system" makes shit up more than half of the time. For its "o4-mini" model, the rate is ***79 percent***
nytimes.com The New York Times @nytimes.com · May 5
The newest and most powerful A.I. technologies — so-called reasoning systems from companies like OpenAI, Google and the Chinese start-up DeepSeek — are generating more errors, not fewer. As their math skills have notably improved, their handle on facts has gotten shakier.
A.I. Hallucinations Are Getting Worse, Even as New Systems Become More Powerful
A new wave of “reasoning” systems from companies like OpenAI is producing incorrect information more often. Even the companies don’t know why.

Decades of research that American taxpayers have invested in is being imperiled at universities like mine. Our paper wrote about some of the projects affected www.columbiaspectator.com/news/2025/04...
Ezra Susser, CC ’74, Public Health ’82, Public Health ’92, professor of epidemiology and psychiatry at the Mailman School of Public Health, said that hearing that two of his grants were cancelled was “soul-crushing.” He said the cuts are affecting a “whole legacy of work.” Susser’s grants were for his research on the genomics of schizophrenia in South Africa and for a psychiatric epidemiology training program. “We had two more years, really, to finish it,” Susser said about his study on schizophrenia. “And we’ve been working on it for 10 years or 12 years, officially, but for at least 15 years, and all that could be lost.”

Every single university president should be asked, in public, why they are not speaking out this way to support all the students currently detained without due process, and all those terrified that they will be next, on every campus in this country. Yes, including Columbia's acting president.

NEW: Tufts files a declaration in support of Rümeysa Öztürk: "The University has no information to support the allegations that she was engaged in activities at Tufts that warrant her arrest and detention." www.tufts.edu/president/sp...
4. With her consent, the University can confirm that Ms. Oztürk is a third-year doctoral student in good academic and administrative standing. Her research focuses on how young adults can use social media in positive, prosocial ways and she is described by her faculty as a hard-working student dedicated to her studies and the Tufts community. The University has no information to support the allegations that she was engaged in activities at Tufts that warrant her arrest and detention. The University has seen an outpouring of support for Ms. Öztürk over the last week from Tufts students, faculty and staff. These individuals have described Ms. Öztürk as a valued member of the community, dedicated to her academic pursuits and committed to her colleagues.
