My tweets are not a news outlet (i.e. "All the News That's Fit to Print"). I tweet what I find interesting. I don't tweet things that are stated frequently or better by others. My goal is not to please all readers but simply to amuse myself.
Observed paradox in AI in medicine @NEJM_AI ai.nejm.org/doi/full/10.10… but I suspect as fast as you move the goal posts, AI will be there soon enough. @emollick
A crucial point about human abilities, which I emphasize in my intro psych lectures: In AI, the "hard problems" (in this case, acrobatics) are easy, and the "easy problems" (doing useful things with objects) are hard.
In universities today, hyping results gets you promoted. Finding the truth just gets you in trouble.
Don't do this. Apheresis systems are full of plastic. Oh yeah, there is also no evidence it works and carries significant risks (for example serious infections, bleeding, death) sciencealert.com/celebrity-unde…
Akin to the Generalist-Specialist paradox we are starting to see in medical AI as described in @NEJM_AI ai.nejm.org/doi/pdf/10.105…
I'm observing a mini Moravec's paradox within robotics: gymnastics that are difficult for humans are much easier for robots than "unsexy" tasks like cooking, cleaning, and assembling. It leads to a cognitive dissonance for people outside the field, "so, robots can parkour &…
Doesn't matter if theres 1000 cohort studies confounded designs are confounded data which is not knowledge this is pseudoscience activity is good is it 7k vs 6k or 8k? we won't know until someone randomizes step thresholds Be active to extent you feel healthy & realistic
in case you are wondering this is academia now
ICML’s Statement about subversive hidden LLM prompts We live in a weird timeline…
this is how media narrative works CBER Director overrules on COVID vaccine to ensure more in line with evidence -gets skewered CBER Director overrules to approve a drug based on no evidence of benefit & worry harm signal -hardly a blip (until now with 3 deaths)

Two weeks ago, I posted about this @CellCellPress paper. As it drew more attention than I'm used to, I wrote a longer piece with my thoughts. Beyond the points made before, I also address some of the feedback on the original tweet👇
I read this Cell paper that argues to have discovered a molecule (betaine) that mimics the geroprotective effects of exercise. This is a very valuable multi-omics resource, but the authors seemed to get caught in the rabbit hole of chasing a high-impact narrative🧵
Sadly bad behavior in academia abounds because hardly anybody powerful or senior is willing to speak out Those of us who have spoken out, often pay a real price
One of the hardest things to accept is how many colleagues stay silent. Not because they don’t agree or don’t want to help, but because speaking up could cost them a grant, a title, or a seat at some table. Some even echo university administration talking lines, knowing full…
We don’t just need more funding. We need new institutions. Ones where research is the mission not an excuse for more administration.
Nope. But eating right, treating blood pressure, getting to a healthy weight, exercising, and not smoking might.
5 minutes in a sauna 4x/week reduces cardiovascular risk by 50%
False. But controlling your BP, cholesterol, blood sugar, maintaining healthy weight, exercising, not smoking does cut your CVD risk.

Generalization does not go as expected and fine-tuning does not substitute for RAG. From @NEJM_AI a study by @ericwu93 @james_y_zou on fine-tuning frontier LLM's with medical data. More in the reply below
Perspective on Covid vaccines and myocarditis from @VPrasadMDMPH and @DrMakaryFDA So many people tried to hide this. I and others were attacked and deplatformed for pointing out this issue. jamanetwork.com/journals/jama/…
