The ceiling on how bad it can be is much _much_ lower than "it doesn't instantaneously kill you". It also doesn't dramatically decrease fertility, or cause significant increases in cancer rates, etc. etc. etc. Any effects it has, by definition, _have_ to be subtle and minor or else we would know. Subtle like "doesn't obviously appear over the course of decades and across tens of millions of people". That is _extremely_ minor.

And because I mentioned fertility and two other people have already mentioned sperm counts, I'm gong to get out in front of that one: We aren't even sure sperm counts are actually decreasing [0], let alone that they are caused by plastics

Indeed. So? Again if you want to code in Haskell or Rust, those are fine choices. What you want, you can't have absent a complete rework of C's type system. And you don't actually want that.
musicians often use them to generate distortion, which is purely an electrical phenomenon. germanium components tend to filter high frequencies and don't clip as sharply as silicon, generating tonal effects that can't really be replicated.

but mostly, a lot of early guitar pedals used germanium components, and so they are associated with prestigious historic guitar players.

here's a video demonstration. silicon first, then halfway through they flip the switches and play the same circuit with germanium components.

The world's leading science journal publishing grand claims without verification, in the face of mounting evidence that the claims might be incorrect, is most certainly not "the scientific method".

What nonsense. Why would that be infeasible?
Never mind that any half decent amp design biases the base voltage to make sure that you're not going to have that problem.
Falls into the bucket of "specialists can have weird hobbies" element though - i.e. the background to do this is basically "has access to lead oxide, copper and red phosphorous" and "a kiln" - particularly if you dispense with trying to do the vacuum synthesis as that account claimed too (also a point in favor: having random access to dangerous chemicals is sort of something I'd expect out of states with less enforcement of drug synthesis laws).

The mechanism is plausible - if the reaction actually proceeds by driving off the sulfate and substituting in the copper at high temperature, it's entirely possible the vacuum synthesis of the authors is unnecessary (I have in fact had personal experience with trying to replicate a paper where it turned out that a pretty important step was acting as an oxygen-diffusion rate-limiter, and this just...wasn't identified at all by the papers authors).
We actually are not sure that sperm counts are dropping globally. The quality of evidence is extremely poor: https://astralcodexten.substack.com/p/declining-sperm-count-...

But no matter what effect they have, if you can't conclusively prove it after decades and millions of people, it's by definition pretty minor.

For these papers in particular, it seems like peer review was badly needed before publication. Sure, it's a meme that Reviewer 2 is always going to complain that could you please run like, 50 more experiments, and for something as potentially groundbreaking as room-temp superconductor, even more so.

But one of the main issues with the papers right now is their chemistry is deficient. The key chemical reactions don't balance, and there's also an unexpected and unexplained oxidation state change in the copper. This is the kind of issue that would be flagged quickly in peer review, and it's the sort of catastrophic paper issue that makes replication problematic--how can you be sure that you're comparing against what the original sample was?
I'd be very curious how much of that evidence is a) realistic dosages and b) in humans (actual humans not human cells in a dish). My guess is very close to none.

Why it (and what I presume is its DAC) have had their surfaces scratched off is beyond me;

The author seems to have arrived at the answer later in the article:

I assume these opaque parts codes were meant at least in part to make things a little harder for bootleggers. Sure, you can’t stop them, but you can slow them down.

Custom parts are difficult enough to RE, but a common trick was (and to some extent still is) to grind off the markings on common parts. Remember that this is in the 80s, where large databases of ICs, sortable by pinout, were basically nonexistent.

Ironically, with the degradation of search engines today, IC part numbers and markings have gotten far more difficult to find too, since there are now so many more companies making parts but search engines are barely indexing them. One wonders if that's a deliberate move from anti-right-to-repair advocates.
If you are a human who wrote that statement, you are a conscious being with free will. You know this to be true through your direct experience. It is not subject to debate or falsification, and it is not merely a model.

Any attempt to debate this point is self-refuting.
The problem is that repetitive work is inherently injurious. Also, working under high pressure is very likely to lead to mistakes that cause injury.

I did hard physical labor for eight years and felt great (it's honestly the best I've ever felt physically and I miss it), but I did not do repetitive work or work under extreme pressure. We were always strongly encouraged to take tons of water breaks, not rush, switch tasks several times a day, and stop working immediately if something started hurting or didn't feel right.

If people are regularly wearing themselves out on physical labor, it's the fault of management.
So load it with an electrical generator and use power electronics to present a constant load. Problem solved.

Many old high efficiency engine designs were discarded because they had poor torque characteristics at the bottom end of their speed range. This is because they were coupled directly to the load through gears. That does not have to be a requirement any more.

There are so many bad DFT papers out there because it's cheap to do DFT compared to growing and measuring samples carefully. DFT is notoriously unreliable as a predictive tool in strongly correlated systems, though when electron correlations are small it works well. I mean, I want this to be true, but I put little stock in DFT that doesn't calculate observables. So yes, you're right.

Seems my headphones can replicate it judging from hearing the audio. Am I missing something?
Most superconducting logic families aren't using transistors at all. They use Josephson junctions, which are just two pieces of superconductor separated by a non-supercondutor. RSFQ (Rapid Single Flux Quantum) uses millivolt-high picosecond-long pulses to represent logic 1 and their absence as logic zero, instead of using voltage level as in CMOS.

You are correct, and that was actually my first thought. If you win (1st, 2nd, or 3rd place), they have rights to your game and the right to make their own derivative works. And you have rights to make derivative works. But then I thought of how this could play out.

So you make "UltraCiv" for the competition and win. You decide that it was a good idea and decide to expand on it. You make "UltraCiv: Election Paradox". Now you have something successful. They make "UltraCiv: City Manager". You can't stop them, because you already gave them permanent rights. They claim that they only use it for "educational use", which is 100% true, since it is an educational game. So was Oregon Trail. In this case, however, your franchise is tainted.

It's just poisioning your own well and IP.

Again, someone will win $20k, but that someone won't be me. I'll put my efforts elsewhere.

Everyone in this thread needs to understand that particularly for materials science, and particularly when there is bad methodology documentation, it is really, really normal for early replication attempts to fail. What works in one lab will often need to be adjusted to work in another, with different equipment, altitude, humidity, all sorts of stuff. Making it even worse, apparently the original team can't even get production correct in more than 10% of runs! Combined with the slipshod methodology, doesn't this make you feel like it was silly to release the arXiv paper when they did? Well, the LK-99 team agree, according to them it was a rogue industrial scientist that they'd apparently fired four months ago who published it to arXiv with himself listed as third author. They wanted more time to nail down sample production and otherwise make a paper to their standards before release, but it effectively leaked and to avoid having credit taken from them for potentially months (or like, forever - science can be brutal) some of them decided to publish what they had on hand within a few hours. This sucks for them, a lot. I don't believe that their intention was to put out work with errors in it or incomplete methodology.

Secondly, this all happened two days ago! If the methodology was perfect, I still wouldn't expect good replication results back within two (part non-business!) days.

I don't know if this material is legit. I really hope it is. But the process of figuring that out could potentially take months (or more), and a two-day-later failed to replicate is not a death sentence.

As much as it sucks, this is really just going to take time to prove it's not a superconductor. If it is a superconductor, we may not know for a while either, unless one of the influencers/"makers" attempting to reproduce the material succeeds and posts some good convincing video of flux pinning or other Meissner effect stuff (that person is going to go insanely viral, if it happens).
I sometimes wonder what it would have been like to witness the emergence of fundamental new technologies, like electricity or radio.

Then I remember I'm further along the tech tree than they were, and what a gift that is. It's very exciting to watch it update in real time.

Now I'm envious of future generations (I think humanity has a bright future despite the current gloom groupthink).
If you’re surrounded by dangers, you literally have to ignore some of them while you fight off the others. There is no way to fight every problem at once.

Extraordinary claims require extraordinary evidence.

But seriously, why can't they ship their sample somewhere?
There's value in that, but I think dealing with two vendors (web servers and database) is not terrible, based on my limited experience so far as a hobbyist developer with Deno Deploy and Neon.

The differences between Deno running locally and Deno Deploy can be a bit annoying, such as not supporting npm's on Deploy yet. I expect that will improve.

My development environment is pretty light: Deno itself and VS Code. So far I haven't needed to set up a database locally, or even install any client-side Postgres tools. (The database driver is an npm library that wraps fetch.)

Probably the same type of dynamic advertising I get when listening to US podcasts with inverted French-speaking ads.

Theory confirming experiment is quite different from theory predicting new physics. I think the best use of these types of ab initio DFT calculations is to interpret experimental results. Back in grad school, my theoretical chemistry group regularly was able to help clear up confusing experimental findings with these exact type of calculations (in fact using the same program as used in this paper, VASP).

I always found it interesting that the plastics we think of - nylon, polyethylene, Teflon, etc. - are man-made and that there are actually naturally occurring plastics, or polymers such as pectin, cellulose, silk, and wool.

The shapes, opacity, and colors of man-made objects made of plastic were what I always thought of, not pectin or wool, or our own protein and DNA in our bodies. The synthetic vs. natural dichotomy or phrasing made that seem non-intuitive.

I am not saying microplastics or polymers are not harmful. It just makes me think of it as less of an alien molecule or structure because it's man-made when I became aware of what polymer, or plastic, actually meant. I am also hoping that maybe there is less of concern to worry, but not that they are not doing harm.

I am old enough to remember milk delivered in glass bottles, paper bags, and wax paper liquid containers before plastic took over. Even soda was in glass bottles. All of my children were breast fed and raised with glassware and steel utensils. I buy the wax paper containers of milk and juices, so who knows what's in those?

Even the article mentions they don't know accumulation levels yet, and what does microplastics and nanoparticles in the 4.2 million to 1.2 billion particles respectively plastic shed per square centimeter mean in terms of molarity in a liter of blood and does it accumulate and keep building up? A lot of unanswered questions and another thing to add to the dread pile.
Wind + solar + hydro can go well past 50% without any batteries. Batteries are getting ever less expensive and production just keeps ramping up even faster.

Then why do we have separate names for Graphite and Diamond? Same element, different molecular (crystalline) structures. If CuO25P6Pb9 can exhibit superconducting properties, and reproduction attempts are failing, then there must be a specific isomer that needs to be achieved, the creation of which is not described in the LK-99 paper.

X is a free public service funded largely by advertisers.

Be careful what you wish for. It is arguably disputable if it really is a "public service" and the use of that term promiscuously, will possibly incur consequences. It's freely available, with conditions, it's publicly visible, again with conditions, it's nothing like unfettered.

I'd be very surprised if the T&C describe it that simply: it will be qualified, somehow.

Normally I wouldn't quibble, but in context this is a statement which I find extraordinary. I would have to believe the legal department knew what they were doing.

Maybe I over-react to what "public service" means distinct from "public" and "service" alone.

I’m currently in a Twitter space with some accounts who know more about this process and this question was answered a few minutes ago. To summarize: no one has yet found a way to “steer” which sites get Cu and which ones don’t.

Someone in the space said “if you find a way to get the Cu to the right site that’s a Nobel Prize”

Same molecular structure entirely different crystal lattice.

It is the formation that is different not the molecules. C = C. They are technically allotropes:

And just like here that's a function of how the bulk carbon got to be formed, under extreme pressure and temperatures or less pressure and temperature. It's the recipe that makes the difference, not the ingredients.
