Room-Temperature Superconductivity, Revisited
After a year of retractions and replications, where does the search for ambient superconductors actually stand?

Few claims in modern physics have collapsed as publicly as the room-temperature superconductor. And yet the underlying ambition is sound: a material that carries current without loss at ambient conditions would reorganize the energy economy.
The lesson of the past year is methodological. Resistance dropping to zero is necessary but not sufficient; the Meissner effect, isotope shifts, and reproducible synthesis must all line up.
Hydride compounds under extreme pressure remain the most credible high-temperature superconductors we know of — the catch being the pressure of a planetary core.
Progress here will be incremental and unglamorous: better characterization, shared samples, and a community that treats extraordinary claims with proportionate skepticism.
