Thanks, but I simply quote "hint of near-room-temperature superconductivity" from the article. AFAIK the original title still contains too much details (the composition） for general audience on HN. Of course, the way I change the title will result in more clicks, so it could be "clickbait" in a way.

So how do I know that which title serves better? I'll appreciate the comments in this special case if it is hard to say in general.
