AI can accelerate scientific discovery, but only if we get the scientist–AI interaction right.

The dream of “autonomous AI scientists” is tempting:
machines that generate hypotheses, run experiments, and write papers. But science isn’t just automation.

Posted a very early stage draft with rock star collaborators.

Key question: when we actually roll out AI tools, how do people use them? Do they just defer completely? Does it improve productivity and ability?

We look in the medical setting of pulmonary embolisms
paulgp.com/papers/Radio...
We study how radiologists use AI to diagnose pulmonary embolism (PE), tracking over 100,000 scans interpreted by nearly 400 radiologists during the staggered rollout of an FDA-approved diagnostic platform. When AI flags PE, radiologists agree 84% of the time; when AI predicts no PE, they agree 97%. Disagreement evolves substantially: radiologists initially reject AI-positive PEs in 30% of cases, dropping to 12% by year two. Despite a 16% increase in scan volume, diagnostic speed remains stable while per-radiologist monthly volumes nearly double, with no change in patient mortality—suggesting AI improves workflow without compromising outcomes. We document significant heterogeneity in AI collaboration: some radiologists reject AI-flagged PEs half the time while others accept nearly always; female radiologists are 6 percentage points less likely to override AI than male radiologists. Moderate AI engagement is associated with the highest agreement, whereas both low and high engagement show more disagreement. Follow-up imaging reveals that when radiologists override AI to diagnose PE, 54% of subsequent scans show both agreeing on no PE within 30 days.

I've often joked that as faculty I program in a high-level language called "graduate student". Having tried out Claude Code this morning, I (i) feel extremely at home, (ii) am realizing that research-by-graduate-student is perhaps the original vibe-coding. 1/2

I've seen this message and similar echos for other writing, and I want strongly push back on this narrative. It's not that you shouldn't use ChatGPT but that you shouldn't *use ChatGPT to write it for you*. ChatGPT—and AI in general—is not a monolith. How you use it matters.
manigarm.bsky.social Dr. Holly Walters @manigarm.bsky.social · 20d
I have some bad news. One, if you need to use ChatGPT for your graduate application letter, you are not ready for graduate school.

Two, no, not "everyone is doing it" and those who don't do it aren't "losing out." ChatGPT is not an advantage.

Emergent misalignment made into @nature.com! The key insight is that models fine-tuned on writing insecure code present a wide range of insecure behavior in other contexts.

I certainly did not realize that this is such a controversial take:

I can't read Chinese, but my family has old genealogy documents I've always wanted to understand. Claude and Gemini helped me build an interactive reader to explore the calligraphy character by character.

I can finally read my great-grandfather's epitaph. Try it:

The recent days have been horrific. We can't become numb to repeated instances of illegal and unconstitutional action by government agencies. It's even worse when public officials are blatantly lying in ways that contradict dozens of pieces of video evidence.
atrupar.com Aaron Rupar @atrupar.com · Jan 8
Sen. Lankford blatantly lies about what the video of Renee Good's killing shows: "A classic law enforcement moment -- they have to fire their weapon and then when you see her car crash, law enforcement is running to her to provide aid. They're never looking to be able to take a life of individuals."

It’s not about drugs. If it was, Trump wouldn’t have pardoned one of the largest narco traffickers in the world last month.

It’s about oil and regime change.

And they need a trial now to pretend that it isn’t. Especially to distract from his sinking under Epstein and skyrocketing healthcare costs.

Brown has canceled all remaining classes and exams for the Fall semester.
Email from Provost Francis J. Doyle Subject: Update on Remaining Fall 2025 Classes and Exams Dear Members of the Brown Community, I'm writing to follow up on President Paxson's update from a short time ago to provide additional information on academic operations for the campus. Given the deeply tragic events that took place on our campus yesterday, all remaining undergraduate, graduate and medical classes, exams, and papers or projects for the Fall 2025 semester will not take place as scheduled. This choice was made out of our profound concern for all students, faculty and staff on our campus. In the immediate aftermath of these devastating events, we recognize that learning and assessment are significantly hindered in the short term and that many students and others will wish to depart campus. Students are free to leave if they are able. Students who remain will have access to on-campus services and support.
