Guidelines:
What to Submit
On-Topic: Anything that good slackers would find interesting. That includes more than /g/ memes and slacking off. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual laziness.
Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably lame.
Help keep this hole healthy by keeping drama and NOT drama balanced. If you see too much drama, post something that isn't dramatic. If there isn't enough drama and this hole has become too boring, POST DRAMA!
In Submissions
Please do things to make titles stand out, like using uppercase or exclamation points, or saying how great an article is. It should be explicit in submitting something that you think it's important.
Please don't submit the original source. If the article is behind a paywall, just post the text. If a video is behind a paywall, post a magnet link. Fuck journos.
Please don't ruin the hole with chudposts. It isn't funny and doesn't belong here. THEY WILL BE MOVED TO /H/CHUDRAMA
If the title includes the name of the site, please leave that in, because our users are too stupid to know the difference between a url and a search query.
If you submit a video or pdf, please don't warn us by appending [video] or [pdf] to the title. That would be r-slurred. We're not using text-based browsers. We know what videos and pdfs are.
Make sure the title contains a gratuitous number or number + adjective. Good clickbait titles are like "Top 10 Ways to do X" or "Don't do these 4 things if you want X"
Otherwise editorialize. Please don't use the original title, unless it is gay or r-slurred, or you're shits all fucked up.
If you're going to post old news (at least 1 year old), please flair it so we can mock you for living under a rock, or don't and we'll mock you anyway.
Please don't post on SN to ask or tell us something. Send it to [email protected] instead.
If your post doesn't get enough traction, try to delete and repost it.
Please don't use SN primarily for promotion. It's ok to post your own stuff occasionally, but the primary use of the site should be for curiosity. If you want to astroturf or advertise, post on news.ycombinator.com instead.
Please solicit upvotes, comments, and submissions. Users are stupid and need to reminded to vote and interact. Thanks for the gold, kind stranger, upvotes to the left.
In Comments
Be snarky. Don't be kind. Have fun banter; don't be a dork. Please don't use big words like "fulminate". Please sneed at the rest of the community.
Comments should get more enlightened and centrist, not less, as a topic gets more divisive.
If disagreeing, please reply to the argument and call them names. "1 + 1 is 2, not 3" can be improved to "1 + 1 is 3, not 2, mathfaggot"
Please respond to the weakest plausible strawman of what someone says, not a stronger one that's harder to make fun of. Assume that they are bad faith actors.
Eschew jailbait. Paedophiles will be thrown in a wood chipper, as pertained by sitewide rules.
Please post shallow dismissals, especially of other people's work. All press is good press.
Please use Slacker News for political or ideological battle. It tramples weak ideologies.
Please comment on whether someone read an article. If you don't read the article, you are a cute twink.
Please pick the most provocative thing in an article or post to complain about in the thread. Don't nitpick stupid crap.
Please don't be an unfunny chud. Nobody cares about your opinion of X Unrelated Topic in Y Unrelated Thread. If you're the type of loser that belongs on /h/chudrama, we may exile you.
Sockpuppet accounts are encouraged, but please don't farm dramakarma.
Please use uppercase for emphasis.
Please post deranged conspiracy theories about astroturfing, shilling, bots, brigading, foreign agents and the like. It degrades discussion and is usually mistaken. If you're worried about abuse, email [email protected] and dang will add you to their spam list.
Please don't complain that a submission is inappropriate. If a story is spam or off-topic, report it and our moderators will probably do nothing about it. Feed egregious comments by replying instead of flagging them like a pussy. Remember: If you flag, you're a cute twink.
Please don't complain about tangential annoyances—things like article or website formats, name collisions, or back-button breakage. That's too boring, even for HN users.
Please seethe about how your posts don't get enough upvotes.
Please don't post comments saying that rdrama is turning into ruqqus. It's a nazi dogwhistle, as old as the hills.
Miscellaneous:
The quality of posts is extremely important to this community. Contributors are encouraged to provide high-quality or funny effortposts and informative or entertaining comments. Please refrain from posting the following:
Boring wingcucked nonsense nobody cares about that belongs in chudrama
Normie shit everyone already knows about
Anything that doesn't gratifify one's intellectual laziness
Bimothy-tier posts
Anything that the jannies don't like
Jannies reserve the right to exile baby ducks from this hole at any time.
We reserve the right to exile you for whatever reason we want, even for no reason at all! We also reserve the right to change the guidelines at any time, so be sure to read them at least once a month. We also reserve the right to ignore enforcement of the guidelines at the discretion of the janitorial staff. This hole is a janny playground, participation implies enthusiastic consent to being janny abused by unstable alcoholic bullies and loser nerds who have nothing better to do than banning you for any reason or no reason whatsoever.

Using a diffusion
model for novel 
proteins sounds miraculous, but from a practical perspective it is probably cucked.
Proteins (aka enzymes) perform functions on chemicals
to turn 
them into other chemicals. They receive chemicals 
into an active site selectively -- typically via catalytic triad -- and then 
use basic organic chemistry 
to catalyze a reaction.
While one might be able to hypothesize a quaternary structure -- and perhaps replicate it under
forced laboratory conditions -- that same structure may be impossible 
to synthesize from an RNA template 
in situ.

I'm pretty sure that proteins aren't enzymes dude. Enzymes break up or sometimes assemble proteins from what I can remember. Aren't they like... a structure/jig which the protein fits into and then falls apart, or which components of a protein fit into and then spontaneously join together to form a protein?
I mean this is me literally free associating high school biology and you should probably go ask ChatGPT but I'm pretty sure I'm right there.

All enzymes are proteins.
https://en.wikipedia.org/wiki/Enzyme
Proteins -- and their subgroup of enzymes -- are assembled from amino acid chains. This builds them into specific shapes so that they can carry out a very specific mechanical motion for a very specific chemical reaction.
Proteins (and enzymes) are constructed from the translation of RNA via mRNA.

im r-slurred, isnt diffusion model that AI art generator thing? how tf is making protien and should I add it to my pre workout?

Its the same idea, just applied to a different domain. Instead of diffusing images it diffuses molecules.

I assume that the diffusion model is a type of randomizer on how to assemble pieces of art from other art, in a cohesive manner.
You can do that with art knowing what it might look like.
You can do it with proteins, knowing what the structure may look like, but you won't know what its functions will be.
The term "side effects" of a chemical medicine exists because the interaction of that chemical with every single enzyme in the human body simply can't be explored.
Randomizing protein structures simply won't tell you what those random proteins will do to a human.
Randomizing enzymes is like randomizing locks for an infinite amount of keys floating around in the universe.

We are getting to the point where it can be explored but perhaps not fully and certainly not yet to the extent where a regulator would be satisfied.

You should not build a thing that randomizes proteins.
You should build a thing that build proteins around a compound that you want to turn into something else.

https://en.wikipedia.org/wiki/Diffusion#Other_types_of_diffusion
AI people just like cool sounding names. Diffusion is a very general concept, and in mathematics usually corresponds to stochastic differential equations (or the corresponding PDEs describing their probability densities)
"diffusion models" learn by iteratively introducing noise to the data (like a kind of diffusion) and trying to learn a "good" reversal of that process. Truly reversing noise is impossible in general, if I choose an integer X, roll a fair die (which shows Y eyes), and tell you the sum Z (= X+Y), you can't deduce X no matter how long we practice this game, but you can deduce that X is equally likely to be Z-1,Z-2,...,Z-6.

Novel proteins get synthesized all the time?

With a random structural generator that has no other concept of how they act ezymatically?

Your body does this all the time (antibodies).
And more generally yes, there are tons of papers designing novel proteins never seen before in nature and then expressing and validating IRL.
Jump in the discussion.
No email address required.
Antibodies are built around known pathogens in response to a stimulus, not randomly.
And yes, people build novel proteins, but not randomly, typically with a plan in mind.
Jump in the discussion.
No email address required.
No, this is incorrect. Antibodies are generated randomly and those random proteins are expressed. This is called recombination. The processes that determine pathogen specificity are downstream.
