Or Beijing, since they apparently have fully replicated it.

I don't know why so many institutions and scientists are so quick to call it nothing. It feels like hubris to me, the scientists in Korea spent many years on it, if it were so easy to dismiss I don't think that would have continued their research... right?

> The superconducting-like behavior in LK-99 most likely originates from a magnitude reduction in resistivity caused by the first-order structural phase transition of Cu2S

The preprint you are citing is explicitly dismisses the sharp transition seen as being non-superconducting.

Nah, I know. But it still looks like a similar material, no?

Even if it looks unlikely to be superconducting, I still think people should remain level headed about it. They spent a lot of time and effort on it.
