Scientists Question Superconductivity Claim from Physicist Accused of Plagiarism

They buried the lede in the bottom third of the story via this tangential comment:

> Last week, a different group of scientists at institutes in South Korea and at William & Mary in Virginia claimed they saw superconductivity without extreme conditions in a lead compound in the presence of copper, but scientists have said they are skeptical about the findings, posted ahead of peer review to arXiv.

For reference, this is not about the recent superconductor discoveries.

Rather, this article is about Ranga Dias, the disgraced physicist who made prior claims.

What is there to question exactly? This is not a philosophical discussion, but hard science. Can this experiment be replicated or not?

Several scientists and labs have raised doubts about Ranga Dias’s room-temperature superconductor
