>Why is it _necessary_ for other labs to produce the material themselves to _verify_ the claims? I highlighted "necessary" and "verify" because your wording of your question somewhat hides the motivations of the labs. Multiple labs around the world are not just doing a "homework assignment" to academically verify someone else's work. Instead, the tantalizing idea of a "room-temperature superconductor" would be a miracle material and That Scientific Leap In Progress is why independent labs are racing to reproduce it. Same excitement of so-called "replication" would happen if somebody put out a plausible "cold fusion" paper or a workable synthesis of a new "drug molecule" to cure cancer. Multiple labs around the world would be motivated to implement their own cold fusion machine and cancer drug. It isn't "necessary" that they replicate it. Instead, they're genuinely excited about making their own miracle devices/drugs and possibly extending the scientific discoveries beyond the original authors' findings.
