    I’m not even smart enough to understand this headline

      Superconductor. It’s baa-aaack!

    And how is this different than LK-99, which was pretty conclusively proven to not be superconductive?

      It has already replicated, with two separate labs in China confirming the results. When LK-99 was announced, it was still awaiting replication. The chemical difference appears to be that this thing has sulphur where LK-99 did not.

    A potential “room-temperature” semiconductor?

        Oh no, a potential revolution in technology, again. How tedious.

          copper substituted lead apatite is literally what lk-99 was. Obviously the exact number and process could be different but colour me extremely skeptical after how that played out.

          Call me when it gets past being a headline in some tech journal.

      There are many room-temperature semiconductors, for example silicon.

      Meissner effect is related to superconductors

        Pretty much all my semiconductors operate well above room temperature! (relatively)

    "The Meissner effect (or Meißner–Ochsenfeld effect) is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state when it is cooled below the critical temperature. This expulsion will repel a nearby magnet. " - from wikipedia. I had to look it up.
