It doesn't even matter if it works or not as for whether it's newsworthy; the mystery, human backstory, and Argonne/China/independent scientists jumping to replicate alone is a whole swathe of viable and fascinating topics ready to be published.
The crazy thing is NYT just bothered to publish a story about the Dias superconductor paper retraction; a paper that had never even crossed my radar in the first place because TBH I don't care about superconductors unless they're going to be a huge step change in practical applications, which the Dias "finding" wasn't.
What are they doing?!
