If LK-99 is the real deal, it could be a game-changer for everything from quantum computing and medical imaging to energy and transportation. But there are a lot of red flags. If LK-99 is the real ...

If there was any hope remaining that LK-99 might be a room-temperature superconductor, it’s pretty much dead now. In fact, it’s worse than that. Pure samples of the substance show that it is an ...

Experts continue to push back against extraordinary claims of a room-temperature superconductor. But even a flop could open up new pathways for materials research. Jackson Ryan was CNET's science ...

A newly discovered material called LK-99 kicked off a frenzy to see if it really was a game-changing superconductor. The results are disappointing. A newly discovered material called LK-99 kicked off ...
