New replication video coming from China https://twitter.com/lereguy/status/1686363900651151360

Hang on, wouldn't a sliver of any magnetic material behave like this within a moving magnetic field? This replication is a fail, yes?

From the paper about the replication, they cast strong doubts on the original paper and consider it a fail

Yeah, hnews is the place to be, nobody here is ever excited about anything new.

Don't be to excited, lest you're branded a bro.

You're not being branded a bro for being excited.

I'm astounded that the MSM seems to be ignoring this ATM. I did a Google news search on LK-99 and saw nothing from major publications. A search on the NYTimes returned an article from 1974.

It's still not believed. It's just Twitter that I've seen the juicy stuff, like a (very sketchy) claimed replication from a Russian, and now another claim from a Chinese group.

I could still see this being something "new" but not a true superconductor. If you read the link, there seems to be some kind of discovery brewing, but the original discovers may not have understood what they found.

> They also predict that substituting gold atoms into the Pb(1) site could lead to a material with very similar properties, which will be an extremely interesting idea to put to the test. Since the base material is lead apatite, I had a random thought that maybe medieval alchemists trying to turn lead into gold just had it backward, as doping gold into lead might be a breakthrough. :-)

Now I'm imagining what history would have looked like if the alchemists had indeed stumbled upon a floating lead apatite sample a few centuries ago...

The ring of solomon was a curious mix of metals with a magnet in it. Its inventors were definitely up to something.

I want to believe

And a great many people also want you to believe. Just remember: don't give anyone any money, not until this is properly verified.

Why would I pay any money when I can just cook it up at home?

I think them waiting until there’s more research is preferable to them coming out and making random claims which pan out not to be true.

I think it's more likely that the bulk of folks don't fully comprehend why this would be so important. I would imagine alot of reporters look at the things they could write about and the choices are politics, war, polarizing news, or nerds nerding hard trying to prove other nerds right or wrong, and it just doesn't make the cut.

Not just low... _zero_. That's where things get weird.

Well, you still lose current over time... for example, we had to dump a bucket of electrons into our superconducting, supercooled magnet about every month ago to keep things swirling properly. (The EE I worked with later didn't believe me. See https://en.wikipedia.org/wiki/Superconducting_magnet#Persist... and note that the loss was due to details of magnetic superconductors, not superconductors in general)

If you can extract work from the field generated by the supercurrent, it must come from somewhere. Small supercurrents make small fields, so things like adiabatic CPUs seem interesting.

Though that's like the opposite of how most media operate.

I am also completely baffled by this! So many stupid mouse-model medical discovery stories over the years and actually zero LK-99 coverage.

It doesn't even matter if it works or not as for whether it's newsworthy; the mystery, human backstory, and Argonne/China/independent scientists jumping to replicate alone is a whole swathe of viable and fascinating topics ready to be published.

The crazy thing is NYT just bothered to publish a story about the Dias superconductor paper retraction; a paper that had never even crossed my radar in the first place because TBH I don't care about superconductors unless they're going to be a huge step change in practical applications, which the Dias "finding" wasn't.

What are they doing?!

True, but that hasn't stopped MSM in the past
