Sadly, yeah, this appears to be a solid case against LK-99.
But this is all I ever wanted. This is not validation for all the negative-nellies who were instantly dumping all over the possibility that LK-99 could have been superconductive before these further tests were done. When these sorts of apparent breakthroughs are made the proper response is to do as these people publishing in Nature did - take it seriously enough to actually check it out. That’s the only way to avoid missing out on the actual breakthroughs.
