LK-99 is an online sensation – but replication efforts fall short

A Korean team has claimed to have discovered a superconductor that works at room temperature and ambient pressure, causing a viral sensation. However, initial attempts to replicate the discovery have failed to provide direct evidence of any superconductivity. The team’s compound, named LK-99, is reportedly a superconductor at temperatures above 127 °C. Scientists remain skeptical and have highlighted the dangers associated with amateur replication attempts. Theoretical studies have suggested interesting electronic features in LK-99 but have not found evidence that it is a superconductor under ambient conditions. Some scientists have responded to the hype by creating videos mimicking levitation with everyday materials.
