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.
