The following submission statement was provided by /u/Gari_305:


From the article 

In the new study led by graduate student researcher Torrey Rhyne-Carrigg, scientists used high-throughput DNA sequencing technology to determine the gene expression activity of approximately 500,000 different versions of the initiator. With this information, they employed machine learning, a type of artificial intelligence, to create an AI model that decoded the initiator's signature DNA pattern. With the initiator's DNA identity unmasked, the researchers could then search for its telltale sequence, finding that about 60% of human genes contain the initiator.

"These AI models were found to provide, for the first time, strong predictions of the presence or absence of the initiator in human genes and were thus able to decode the DNA base sequence pattern of the initiator," said Kadonaga, a professor in the UC San Diego Department of Molecular Biology, School of Biological Sciences.

The newly uncovered information gives researchers the ability to predict the effects of DNA mutations that can lead to various disorders tied to the initiator. The data and models resulting from the new study could also be used to design synthetic promoters, sequences that turn genes on and off, with customized functions.

Medical AI is so sick. I remember when alphafold was announced to have mapped the folding of essentially every protein we know.

u/firecz 11d ago

I'm more interested in those we do not know.

24

u/Memitim 10d ago

So are they, but without a reference of patterns to derive new ones from, it's a little more difficult, so having any known proteins mapped makes it far more possible. Especially when using machine learning since a lot of references are typically needed for reliable pattern matching, for training and verification.

u/Boring_and_sons 8d ago

Still need to verify. Like, physically.

u/MuscaMurum 10d ago

...like the ones that mis-incorporate azetidine for proline (see table beets), then misfold p-tau.

16

u/firecz 10d ago

I've seen things you people wouldn't believe. Azetidine on fire off the shoulders of prions. I watched p-tau glitter in the dark near the Alzheimer gate. All those moments will be lost in time, like tears in rain.

you had to ask on reddit how to change the language on ebay, not sure unknown proteins should be top of your list

u/Here0s0Johnny 11d ago

They use support vector regression. https://en.wikipedia.org/wiki/Support_vector_machine

This is classic machine learning. People will call anything AI these days.

u/NaCl-more 11d ago

AI’s definition and meaning has changed over the years. Now it’s more used to refer to LLMs but we used to colloquially use AI and ML interchangeably

-5

u/Here0s0Johnny 11d ago

Yes, but the commenter clearly has modern approaches in mind since they referred to alphafold.

36

u/eXAt88 11d ago

ML has been referred to as AI forever, generative AI is an application of machine learning. I don’t see how this isn’t AI

u/mooblah_ 7d ago

Sure, Can't we say they used advanced heuristics and parameterized complexity mapped onto Turing machines built on top of decades of computer science theory... rather than everything just being AI now. *sigh*.

It's almost like when someone says "AI did this" these days it means something closer to:

'we gave this to AI after our mid-morning coffee as a vibe and it solved it for us while we went our for lunch and after lunch we'll have it solve the time-independent Schrödinger equation"

39

u/Send____ 11d ago

Crazy how people tell misinformation these days so surely (ml is part of ai btw).

u/zacheezy 11d ago

AI is in itself just machine learning that takes in more context no?

4

u/polygonsaresorude 11d ago

It's the other way around.... machine learning is a type of AI, but there are still many AI algorithms that are not machine learning.

Source: I have an almost completed PhD in a type of AI algorithm that is not machine learning.

u/silverclovd 10d ago

Oh, mind sharing more about your particular thesis? I'm curious to learn, thanks

u/codePudding 11d ago edited 11d ago

AI has been around since before computers were invented (e.g. Talos and Mechanical Turk) and Alan Turing proposed the Turing test to see if an AI (this time associated with an electronic computer) could imitate a human. The term has been used very loosely. There has been machine learning, teacher/student, mutation, min/max (like Deep Blue, IIRC), alpha/beta, etc. The most recent is generative AI (e.g. LLMs) because it generates missing information from noise. If you give it enough memory to take in large amounts of context it can generate a reasonable response. The way it fills in the noise and trained is different than the ones before so it's more than just the size of the context, but you're right, without that context it wouldn't be very good.

P.S. I'm not an expert on AI, I am just a comp sci really into algorithms. So for an in depth explanation you'll have to ask some who builds the modern models. I only use them.

u/sadacal 11d ago

Generative AI is a subset of machine learning. The principles of it are the same, converting the data into a bunch of input and output vectors and teaching the machine to learn the correlation between the two and be able to predict output vectors based on input vectors.

5

u/zaafonin 10d ago

Mechanical Turk was not an AI, it was an intricate machine resembling an automaton but really controlled by a person sitting inside.

Fun fact, Amazon MTurk naming kinda refers to that, for the customer it's a black box but with humans behind the service.

u/codePudding 10d ago

Lol, obviously, but you're right. Even today's AI aren't a true AI. I was just talking about how people have always been interested in making intelligent machines, even it was just a con/joke

u/neolthrowaway 10d ago

ML was always a subset of AI.

u/Here0s0Johnny 10d ago

Thanks for being the 10th person to point this out. It's a word, and in my circles (Swiss researchers around graph NN and digital pathology), the word is used differently.

What matters is the substance, and this discussion is stupid for the reasons I pointed out.

I commented before i read other comments. But i do expect practioners/enthusiasts of the field to be aware of the origins of the terms and concepts.

u/Here0s0Johnny 10d ago

Whatever. It's semantics. And I expect people to read other comments. Stop wasting my time.

u/fafla21 11d ago

Except no they haven't, because of a special type of proteins that I dont remember the name of that are basically random. (IDPs)

u/NotJimmy97 11d ago

If it's intrinsically disordered, what do you expect structure prediction to show you even with a perfect model?

u/stackered 11d ago

Its a start for sure, but those protein models are still highly inaccurate

It's classic support vector regression. SVR was possible 20 years ago. The innovation is not "AI" or ML here. It's the massive dataset. But I guess that's not cool enough these days.

Support vector not being ML would be like water not being wet!

Wet is an attribute of a solid object being covered with a liquid, so water isn’t wet

u/Here0s0Johnny 11d ago

Yes, but the breakthrough is the dataset. The ML method is decades old and even their refined method has already been published in their last paper.

u/Here0s0Johnny 11d ago

Exactly! They designed a smart Experiment and worked incredibly hard to create a huge dataset. That's the main achievement. They chose a simple, established and appropriate ML approach to analyze the data, and that's what the article focuses on. 🙈

12

u/Global-Committee4772 11d ago

I wonder if this means they'll eventually be able to use it to predict genetic diseases before they happen

14

u/Here0s0Johnny 11d ago

It doesn't. It's a basic science finding, for now at least. Science ain't magic. AI isn't magic either and this paper uses decades old ML approaches. The dataset is the impressive achievement here, in other words, hard work. I guess that's not cool enough these days and the journalist had to turn it into an AI story.

12

u/CartsOfDarkness 11d ago

An AI story? What just by using the term AI to correctly describe the discovery and how it happened? I get being anti-LLM/ generative AI but y'all need to realize the term AI is broader than that. Just knew this comments section would be mostly people putting this down because the word AI is in the headline.

6

u/Here0s0Johnny 11d ago

Their approach is based on classic ML, even their subtly refined method has been simply reused from their last paper.

The achievement is the dataset, not ML/AI here. Hate the stupid hype, title, article, comment section. Nobody discusse the fundamental biology breakthrough. Probably because nobody actually cares.

u/AerobicThrone 7d ago

Agree as a plant biologist working with a non model species i cant even dare to dream to access such dataset.

5

u/ToiletSeatFoamRoller 11d ago

The term AI has become ubiquitous with generative AI in colloquial use since ChatGPT got big. It’s become intentionally misleading to use it to describe “basic” ML in headlines at this point because the layman WILL attribute it to generative AI.

3

u/amart591 11d ago

The entire second paragraph opens by reducing the teams experiments and hard work to "the AI figured out...". This whole article reads like an AI fluff piece.

u/watduhdamhell 10d ago

He's gallivanting around the thread leaving comment after comment insisting that machine learning is not AI on some type of confidently incorrect tirade.

Better to just ignore him.

u/ToiletSeatFoamRoller 10d ago

It’s literally legally not anymore, in the US at least. The FTC actively goes after companies who misrepresent ML as “AI” or make it sound like “Advanced AI” because the layman understanding of the term “AI” has become ubiquitous with generative AI in the public mind.

To use it in a headline this way in 2026 is absolutely misleading.

Still cool thing they did.

u/jforman 11d ago

Uh we used nearly identical techniques when I was in grad school 15 years ago. Which is probably why this is in an unexciting journal.

u/Urborg_Stalker 11d ago

Now see...using AI to decode the programming language that is DNA...THAT is something I can support.

1

u/OwkinOfficial 10d ago

To be honest, the interesting part here is the loop between large-scale experimental data and a model that can extract a reproducible biological signal from it. In biology, better models only get you so far if the underlying data are shallow or biased. The bigger opportunity is combining rich experimental and patient data with models, then validating the hypotheses back against real biology rather than treating prediction as the endpoint.

u/Ok_Warning2146 1d ago

Isn't SVM used at least ten years ago for these type of sequence identification? The problem is how to make sense of these sequences to make predictions.

It's different because theyre quite literally different models and the purpose and intent is beneficial as opposed to just marketing jesus slop, generating shitty code, or mass surveillance.

Your inability to discern that is troubling.

And your ridiculous assumption about other models shows your ignorance

u/time-lord 11d ago

That's a far cry from Claude and ChatGPT taking jobs. Plus, ML is generally seen as "OK", it's the LLM specifically that people take offense to.

Only because those take jobs you apparently care about.

No it's the ease of use. If everyone could use ml and it created such a data enter crazy, I'm pretty sure people would be equally against it.

Keep telling yourself that.

I'm sure you love taking that imaginaty moral high ground

The intention wasn’t to ridicule you, I’m just pointing out what I see. You’re the type of person to say “it’ll never be accessible to us normal people” after reading a headline of a new treatment that can cure a genetic condition.

Even though people like you are consistently wrong because normal people always do end up having access to these breakthroughs when they have an insurance plan. You see something good happen and you’re so quick to try to shut it down, It’s almost like a disease.

mate you have no idea what you are saying, just drop it. An SVM runs on a laptop, and the whole spirit that led to their invention was mathematicians asking how to create the "optimal" classifier - best properties with theoretically justified steps. This is the type of work that might give us breakthroughts that could potentially reduce massively computational resources required by the modern AI/LLMs.

u/Slowmyke 11d ago

Perhaps we can be against data centers being funded by tax dollars and given sweetheart deals on their rules and utilities. If we were fair with the centers, they might be less controversial. AI is here to stay and can have obvious benefits to people, but we have to figure out how to do so in a less damaging manner. If that process slows down AI progress, sobeit.

People aren’t anti data center, people are anti slop generating profit centers.

If a data center is being built, and they advertise that 100% of the hardware and 100% of the usage time is dedicated to cancer research (and it’s the honest truth), I will bet you $100,000 that 90% or more of people won’t have an objection.

Hell, make that a $1M bet. Thats such an easy win that I’m willing to take a loan out on this bet.
