The two Chinese labs working on replicating LK-99 appear to have found a room-temperature superconductor at ambient pressure. (arxiv.org)

Here's what's different from last time:

it's more like "room temperature" than room temperature, the paper says 250K which is -23 C.
it has already replicated, with two separate labs in China confirming the results.
The chemical difference appears to be that this thing has sulphur where LK-99 did not.

There are tons of useful applications for superconductors that are impractical to do currently. Some examples, include cheap magnetic levitation, fusion containment, computing, power transmission, etc. Finding a superconductor that works at roughly room temperature and ambient pressure has been the holy grail in material science for a little while now. Basically, it would be a huge breakthrough that could allow a lot of new tech we can't currently make.
