Links, sources? This is a weird article, it seems to be a rewrite without sources of a hackaday article, which in turn references a paper that is now 6 days old.

I just wrote a comment in another thread that's relevant here too. It looks like the first superconductor paper was released by a rouge researcher, without the agreement of the other two authors or the rest of the LK-99 group. This forced the LK-99 group to rush to publish the official paper, with a cost to quality. The LK-99 group released v2 a week later (on Saturday), and probably will continue to update it. A premature release explains many of the oddities about the two papers The first paper submitted is titled "The First Room-Temperature Ambient-Pressure Superconductor." It lists three…

It doesn't reproduce: https://arxiv.org/abs/2307.16802. That doesn't mean there's not something to further investigate, but LK-99, at least as described in the paper, is not it.
