I can't speak to math and theoretical CS, because both of those fields now have methods to make proofs that can be verified (and math is probably the only situation where you can "prove" something true; all other fields are effectively probabilistic, not logical in nature).

I disagree with your premise. Part of our job as scientists (thankfully no longer mine) is to reduce the irrelevant and incorrect noisy as early as possible. I have seen so many grad students get excited by a paper and put enormous effort into reproducing somethign that was a false or fake result.

I'm not aware of any fatally flawed paper that leads to the claimed result when done properly. Could you share an example?

Change the word LLM to "teacher" and I think the statement is still true.

You can get a good idea by reading Retraction Watch and following a few papers/scientists who show up in it. That defines the current norms.

To me, a single significant error of any kind brings the entire paper into question. If a less important figure contains an image duplication, that makes me wonder if I can trust any of the images.

The most common and obvious example is image duplication. This is used to invalidate large numbers of paper (I was absolutely shocked at the observed rate of image duplication). I am not sure I would call that a model.

The next example I can think of- I am not sure it qualifies. I read a paper where they deleted one gene at a time in yeast (it has 6000 genes) and determined whether the mutated yeast could live or not. For each gene where the yeast died, they added that to a list of "essential for life" genes. The paper concluded they had found some interesting proteins that should be studied. I read the paper and the first thing that sprang to mind, are any of these genes overlapping? Because we know (somebody already demonstrated in a lab) that genes do overlap (which is truly weird!)

I wrote a script and showed that every gene they reported as essential for life overlapped an already known gene that was essential for life. I wrote the authors, who never responded, but wrote a followup paper where they acknowledged they probably had a high false positive rate due to overlapping genes with known fatal effects. My guess is you'd say that either I used a model (existing literature) or I compared against the world, but realistically, what I did was trivially come up with a better explanation than the authors. T hat's what I want LLMs to do for me, and it seems like the direction LLMs are going will fulfill my desires.

I think you misunderstood. I'm not asking for an oracle that can determine whether a paper is correct, I want an oracle that can find real mistakes in papers (thus invalidating them).

I work full time on "lab in the loop" AI, so I'm pretty familiar with the need for real-world experiments. I am not proposing a fully autonomous scientist that could read an arbitrary paper and emit whether it's universally true without some verification method.

Also, to your statement: " Because by the time you are a practicing scientist, you've developed a feel for what constitutes a satisfying explanation."

I'm a practicing scientist (well, ex-scientist) and it seems like most "satisfying explanations" end up being wrong or incomplete simply because they seem so satisfying.

This is realistic. We already do this today: it's called "journal club". A bunch of grad students read the same paper and then criticize it. I've read papers that I thought were amazing only to. have somebody else notice a key issue in a method, or a conclusion that didn't follow, or outright omission of an important detail, in a way that could be verified by both the students and the authors of the paper.

I think one of the end-game components for AI is to be able to read all the literature and generate a reliable list of which ones are not correct and a convincing reason why.
dekhn··on Biology might not be quantum, but its math is quantumlike
If you filled a classical bag with classical locks and classical keys and shook it for a very long time, you would indeed see a small number of keys in locks. There's a non-zero probability set of steps by which that can happen. Am I missing something obvious here?
dekhn··on Biology might not be quantum, but its math is quantumlike
The real question is whether biology exploits a subset of special quantum phenomena (entanglement, coherence, superposition). Just about everybody in the field acknowledges that biology, being made of chemistry and physics, is "quantum", but in a "boring" way (just the energy calculations), but the bar to convincingly demonstrate exploitation of special phenomena is much higher.

I think it's mainly to be close to the sample collection area while also having a place to do microscopy in semi-privacy. Looking at their equipment, I think they bought everything out of pocket and pay for the hotel on their own.

Right- that's really just a version of a worm pick. I use similar tools (including a mouth pipette... remember kids, in chemistry: don't pipette by mouth, in biology: oops I think I just inhaled something!) working with tardigrade. If it was steampunk there would be some sort of goggles, leather, gears, and a tincture of laudunum.
dekhn··on Allow babywearing carriers on planes
I remember the very first time I installed a car seat, I rigorously followed the instructions, verifying each step both textually and by image. After that, we had it inspected by the local FD who said "you did it wrong" and rearranged it in a way that looked wrong to me (some detail with the straps and routing). I still don't know who did it right.
dekhn··on Why is the liver so weirdly regenerative?
The current model is that evolution acts on the molecular, cellular, and genetic level, and most importantly, at the population level.

To your last paragraph: when opposing something, it makes sense to use the laziest argument first. Only if that doesn't achieve your goals, would you move towards less lazy arguments. I forget what the term for this is, it's generally criticized ("you should just put your strongest arguments first").

dekhn··on Why is the liver so weirdly regenerative?
In retrospect I conclude you're right (that it's splitting a hair). I went back and some literature does use the term self-replication although at least within my academic circles, we consider autocatalyzed template matching simpler than self-replication.
dekhn··on Why is the liver so weirdly regenerative?
No, evolution is not an observation that there are things that replicate. Darwin's view, which has survived mostly intact, is that there is replication with variation and that more fit individuals replicate at a higher rate ("survival of the fittest" isn't a correct description; plenty of less fit individuals do replicate, but they contribute very little to the population genetics in the long run)

And amyloid protein doesn't self-replicate. An instance of the misfolded form causes other folded proteins of the same type to transition to the misfolded form. It's a form of catalysis, not self-replication.

dekhn··on Why is the liver so weirdly regenerative?
the claim isn't complete, either. Recent research has demonstrated adult neurogenesis (growth of new cells that originate from neural stem cells).

dekhn··on Claude discovers a novel enzyme system with CRISPR-like repeats
I think you fundamentally misunderstand both the results published here, and how scientists operating at the highest level of academic research operate. None of these authors has to worry about citing previous work to get the attention of biotech labs.
dekhn··on Claude discovers a novel enzyme system with CRISPR-like repeats
Can you elaborate on what you're thinking? I don't see any support for this being a hallucaination; from what I can see, it's a pretty typical "early biological discovery".

The pre-print authors all have long publication histories.

Pagerank was inspired by academic citation networks; it just turned it in a recursive matrix problem (of which there was some prior literature).

I can't tell- the paper says the harness details are in Sup 1 which I don't think got published.

It's arguable; see the Sapir-Worf hypothesis in the strong and weak forms.
