2025 update because I'm not seeking to hire anyone or sponsor any new students right now. Possible exceptions for people who are *really* allied with my funded work (e.g., on mpox vax, vax misinfo) and/or have access to external funding (e.g., fellowship, home nation). Lab is at capacity for now.

Prospective students: Here's what you need to know if you think you might want to work with me (a thread):

1. I'm not looking to recruit new students at the moment. (There could be some exceptions, especially for research-oriented Master's students in my school or interdisciplinary studies.)

10 days into 2026 the U.S. has:

• Attacked Syria
• Invaded Venezuela - president arrested
• Deployed ICE - U.S. citizens detained and killed
• Threatens to take Greenland
• Overhauled the childhood vaccine schedule - undermining decades of evidence

This is not normal.
Everyone should be alarmed.

NIH is losing so may good people. First they were fired or RIFd or pressured to retire early.

Now they are leaving because “no longer lend our credibility to an organization that has lost its integrity.”

Proud to know these brave scientists!

The NIH has lost its scientific integrity. So we left

“We can no longer lend our credibility to an organization that has lost its integrity,” write four scientists and administrators who recently resigned from the NIH.

Important context: “Considering that titers wane in vaccinated people and that mpox cases among vaccinated individuals are generally less severe, immunity to mpox likely extends beyond antibodies”

Participants with prior infection were more likely than vaccine recipients to retain some detectable antibodies.

Obviously, this can not replace a trained specialist. I'm hoping someone, though, can take (or has already taken) a stab at quantifying how in/accurate major LLMs are with DNA interpretation, much as has started to be done on other topic areas.

Devon Greyson @greyson.bsky.social · 5d

And, while I'm not a geneticist or LLM expert, I assume these embedded assumptions are also easily lost by a content machine that strings together likely sequences of words.

Yeah. I recognize this is a huge red flag for unmet needs of patients (I observed this in a rare genetic disease community, so patients on the margins for whom personalized info/interpretation may actually be needed) and also YIKES is the LLM actually better than nothing? I honestly don’t know.

Devon Greyson @greyson.bsky.social · 6d

Anyone publishing yet about accuracy of chatGPT or other publicly available LLMs in helping patients interpret their DNA? Seeing more and more reports of people feeding LLMs their sequencing from 23 and me or other source and acting on the interpretation, and...I have concerns.

Sadly, the propaganda related to recent Maduro abduction by USA serves as a cautionary tale about taking photos/video at face value. Combo of old (out of context real images) & new (fictitiously generated w “AI”) tactics at play.

THREAD: Viral misinformation on US capture of Nicolas Maduro - 4 January

This video, shared by Alex Jones and others, falsely claims to show millions of Venezuelans in Caracas celebrating Maduro's capture.

In fact, it shows anti-Maduro protests in July 2024 over a highly disputed election.

In a study following 23 million people age 18-59 (pretty young) for 4 years…despite the fact that the ones who got the COVID vaccine were overall older and sicker at baseline, they not only had 74% lower risk of dying from COVID than the unvaccinated but 25% lower risk of dying from any other cause!

Unless I'm missing something, and I'm pretty sure I'm not, Twitter's AI is cranking out CSAM deepfakes, Elon Musk is making jokes about it, and nobody is doing anything to stop it or hold anyone at Twitter accountable for its creation and distribution.

Is that right?

Fellow PIs, what non-technical lab practices or procedures do you have policies about? Trying to assess what is not covered by my school or university level policies but not so technical that it's project/method specific. Things like records/data mgt, authorship guidelines, outside work/collab, etc.

I have never understood the (over)confidence some profs put in the reliability & validity of their exams. Many exams are not particularly well crafted, few are ever validated scientifically, some don’t even seem to align well w overall course learning objectives.

John Scalzi @scalzi.com · 15d

I had a class on Joseph Conrad and on the first day the professor said that the only grade for the class would be the final, and that it would be passage identification. I never showed up to class again, read nine of the ten books the day before the final and aced the test.

Amanda Gapp @amandagapp.bsky.social · 15d

I skipped out on a Music Theory class and showed up for the final, and passed it! Of course, that was just one grade for the semester, sooo.... 😆

I feel like if I can pass your final without showing up, I deserve the credit though. Cause isn't the point to prove I know the material? 😆
