> When copper oxide superconductors were discovered in 1986, researchers leapt to probe their properties. But nearly four decades later, there is still debate over the material’s superconducting mechanism, says Vishik. Efforts to explain LK-99 came readily.

To me, the interesting take-away is that, right at the end. All too often we see peer-review as this slow, inching, excruciating process, particularly in social sciences where it's a de-facto afterthought. It was great to see science chugging ferociously away like a (somewhat!) well-oiled machine, such as the electronic analysis via slightly different methods (e.g. DFT) and the material synthesis efforts by the Argonne NL and Max Planck Institute.

Farewell for now, RTSC.

Side-note: Pure LK-99 is visually beautiful! Who would-a known from those crumbly grey flakes, huh?

That German lab should sell LK-99 crystals. I wouldn't mind buying a souvenir for this whole episode!

I'd like to second this. Bonus points if a magnet were included so that the sample could be "levitated" over it. This is definitely a kind of novelty gift suitable for science-y and geeky friends.
