Will the Dias Lab's report of an N-doped lutetium hydride near-ambient superconductor be replicated by 2025?
closes 2025

The report was published in Nature on March 8th, 2023:

Dasenbrock-Gammon, N., Snider, E., McBride, R. et al. Evidence of near-ambient superconductivity in a N-doped lutetium hydride. Nature 615, 244–250 (2023). https://doi.org/10.1038/s41586-023-05742-0

This will resolve to yes if an independent replication is published in a reputable scientific journal before 01/01/2025.

Admittedly an early pub, without review, but it doesn’t look good for the Dias lab

@craftyvisage Ah! My mistake, I misread that disclaimer

So how does this resolve if there are one or more non-replications? Still wait until 2025?

Yes, wait until 2025.

A hypothesis has been advanced in this paper that different isotopes of Nitrogen might have been used by the Dias Lab (15N) to dope their lutetium hydride compared to potentially (unverified guess) of 14N doping by Hai-hu Wen et. al. One of these isotopes has a negative NMM (15N), the other (14N) has a positive NMM. https://ej-physics.org/index.php/ejphysics/article/view/255

This market is indeed free money. Being passingly familiar with RetractionWatch, and how hard it is to call out even blindingly obvious and not even very effortful fraud, it's easy to see all the signs. Scientists will hem and haw to be polite but "this other time very recently, some of the people in this team fabricated data" overrides any optimism about the paper. The chances of another team independently manipulating their data the same way, which can pretty much only happen intentionally, are minuscule.

Haha this market is free money. It's peer-reviewed and in nature. Yes, obviously this group has stirred controversy before, but there's no way anyone in this field (myself included, as a materials scientist) would give this anything below 50% chance of being replicated.
