Superconductivity

[John Clark]

In March the journal Nature published an article claiming that a room temperature Superconductor had been discovered. 

Evidence of near-ambient superconductivity in a N-doped lutetium hydride

I was a little surprised Nature decided to publish it because the same people made the same claim a few years ago but the journal had to retract it,  and now to their intense embarrassment it looks like history is going to be repeating itself; the lead author sent another paper to the Physical Review Journal and now it looks like they're going to have to retract that paper too:

‘A very disturbing picture’: another retraction imminent for controversial physicist

Meanwhile a completely different group has claimed to have found a different substance that superconducts at room temperature and pressure. I'll believe it when I see it: 

The First Room-Temperature Ambient-Pressure Superconductor

There were two preprints, this is the other one:

So, what is next, manufacturing for zero-G on earth, MagLev trains? Baby Fusion reactors?

We'll have to see! Commentary from experts leans to this result more
likely being due to strong paramagnetism rather than the Meissner effect
characteristic of superconductivity.

Yeah, it sounds a little too good to be true, but I hope I'm wrong.

Well, I am a fool for good news, so lets hope. 

Thanks.
