Possibly more on that superconductivity at ambient room temp thing Kent posted

I don't have enough chemistry background to completely understand the steps, but if it works... the secret sauce seems to be the diamagnetic properties. Did some reading up and it seems that water has diametric properties causing it be repelled slightly went thinly placed on a very strong magnet. Frogs and other critters (with high water content, I suppose) have been levitated if magnets are strong enough. Weird stuff. Thanx for the info, you really did some homework.

I'm just closely monitoring the topic on a few sites with high quality data. [Space Battles forum](https://forums.spacebattles.com/threads/claims-of-room-temperature-and-ambient-pressure-superconductor.1106083/) has a great thread following the situation. The /r/singularity sub is also a good resource. And Zhihu for monitoring the Chinese progress.

First claimed successful replication of LK-99 Accomplished by a team at the Huazhong University of Science and Technology and posted 30 minutes ago. Why this is evidence: The LK-99 flake slightly levitates for both orientations of the magnetic field, meaning it is not simply a magnetized piece of iron or similar 'magnetic material'. A simple magnetic flake would be attracted to one polarity of the strong magnet, and repelled by the other. A diamagnet would be repelled under either orientation, since it resists and expels all fields regardless of the polarity. Caveats There is no way to verify the orientation of the strong magnet in this video, also, there are yet to be published experimental measured values of this sample. Diamagnetism is a property of superconductors but without measured and verified data, this is just suggestive of a result. (emphasis honey's) Take-away If this synthesis was indeed successful, then this material is easy enough to be made by labs other than the original research team. I would watch carefully for results out of Argonne National Lab, who are reported to be working on their own synthesis of a sample. This overall corroborates two independent simulation studies that investigated the original Korean authors claim about material and crystal structure, and both studies supported the claims. Lawrence Berkeley National Lab: https://arxiv.org/pdf/2307.16892.pdf[^] Shenyang National Lab: https://arxiv.org/pdf/2307.16040.pdf[^] Anyway, my takeaway is this is another bit of evidence that points to this being more than just a fluke or a bad experiment. It has been replicated. Can they do it again? Can they get around the limitations of their current methodologies? None of this is peer reviewed yet, to my knowledge so caveat emptor. However, it's extremely interesting.

Thanks for this report, "honey." This is good stuff, and not something that makes the local news. For my purposes, I want to see the current density this tech can support, but I know it's far too soon to expect that.

Wow what a weird website. Interesting to say the least. I'll get back.

I always like to remember the Nature reproducibility paper when hearing about things like this -> 1,500 scientists lift the lid on reproducibility | Nature[^] On the whole individual scientific breakthroughs tend to be quite small, so I tend to be on the skep[tical side when hearing about this sort of thing. Bearing in mind that scientists survive from grants and competition for grant money is fierce, it's always good to be skeptical when claims are made that are not backed by easily reproducible evidence.

Check Sabine Hossenfelder's video on this you YouTube. It's all very dodgy and they have a history of bad science. So in short, yeah nah.

I remain skeptical, yet interested enough to follow the development of this, if that makes sense. I recognize that all prior claims like this have been debunked, and it does give me pause, but not quite enough for me to tune it out. :)

I think that's a reasonable and rational approach you are taking. It's an area I know nothing about and I have seen too many Hyperloops,Theranos and FTxs in my life to not be a little bit cynical on some claims.
