Researchers have discovered indications of superconductivity in a new blend composed mainly of variant apatite and covellite (copper sulfide). By heavily doping sulfur into an apatite framework, they observed significant diamagnetism around 260 K, dropping sharply below 30 K, suggesting the coexistence of two superconducting phases. The upper critical magnetic field exceeded 1000 Oe at 250 K. Electric measurements showed deviations from normal linear behavior, indicating a zero-resistance effect, with a critical current of approximately 50 µA at 140 K. These unique magnetic and electric properties suggest that variant apatite and covellite individually trigger two superconducting phases at temperatures close to room temperature and lower. The study provides insights into the potential for superconductivity in this novel material blend.

10 commentsSince this thread is down from the top, I'm also considering posting another one as soon as the stream link comes out. I'm not sure if this violates the "duplicate" rule of HN, but I think broadcasting such a major physics breakthrough is worth a try.
The materials are cheap and readily available. This could be reproduced by random YouTube chemists, so expect confirmation or not within weeks.
Update: One of the authors have left official comments there. If you have a real-name authenticated account, you can ask the authors about the thing.
