There’s a new, controversial “Holy Grail” of superconductors.

Last week a series of papers examining LK-99, a material with the apparent properties of a room temp superconductor, dropped. The problem is there have been deeply flawed claims of achieving this “Holy Grail” before. Plus the research didn’t appear in a peer-reviewed journal and at least one paper has “many defects” according to one of the LK-99 researchers.

While LK-99 could potentially lead to a generational leap in technology resulting in more efficient power storage, magnetic refrigeration, and major advances in quantum computing, as New Scientist points out, there’s plenty of reason to be skeptical for now.
