Here’s what’s different from last time:

  • it’s more like “room temperature” than room temperature, the paper says 250K which is -23 C.

  • it has already replicated, with two separate labs in China confirming the results.

  • The chemical difference appears to be that this thing has sulphur where LK-99 did not.

    I would suggest not posting research papers as news, especially regarding superconductors which was controversial topic last year. I found a Chinese article that references this tweet, which I assume is where you got your post from:

    The paper’s title uses “Possible Meissner effect near room temperature”, which does not automatically translate into the sensationalist title “room-temperature superconductor”.

    Some of the authors of this paper have responded to questions on Zhihu (something like Chinese Quora) here: https://www.zhihu.com/question/637763289 https://www.zhihu.com/question/637763424

    From what I gathered this paper is a milestone on the road to a “near room temperature superconductor”, and there is optimism but more work needs to be done.

      I think it’s still news worthy. I realize there’s a lot of hype around the subject, but it looks like it has been replicated by two separate labs now.
