    I hope their claim pans out and I find the fact that this link stupidly only mentions the temps and pressures in imperial measurement rather than metric; A classic sign of the usual BS kind of BS pseudoscientific websites I have so often seen in the past! So I will have to reserve judgment on their claim just for now and wait and see whether the real experts say this is valid or BS.
    But, even if their claim does prove correct, don't get too excited because for now the only room temp one they have got only works at extremely high pressures thus making it impractical for common use.

    That is the original source:

    https://www.nature.com/articles/s41586-020-2801-z

    and they do give pressure in GPa and Temperatures in K as scientist routinely do 😉

    Phys.org is a Website for the american public, so they sometimes try to boil down Things or give perspective which is not really warranted by the original report. (as the Claim to have any application in reach.

    well that's a relief! So I now think it is almost certainly valid claim. In the past I have seen huge numbers of BS pseudoscientific websites all over the net and one thing they nearly all have in common is that they state all measurements in imperial units rather than metric so I have come to see that as one of the typical signatures (along with vague BS made-up terms, often containing the word 'natural' in them, pretending to be scientific terms, and also assertions so vague as to have no scientific meaning, which fortunately this link lacked) of a pseudoscientific website which is why I was initially immediately a bit suspicious of this one.

    I'm curious about DeepThought's opinion on this. This is in his wheel-house.

    Sadly enough you are Right here… phys.org I would exempt as I did argue in my previous post.

    267 GPa is about 2.6 million atmospheres, so it's looking a little impractical.

    I have only just found these link about this breakthrough;
    https://physicsworld.com/a/superconductivity-endures-to-15-c-in-high-pressure-material/
    "...Superconductivity endures to 15 °C in high-pressure material
    Superconductivity has been observed at temperatures up to 15 °C in a hydrogen-rich material under immense pressure – shattering the previous high-temperature record by about 35 degrees.
    ...."
    and found this wiki page about this;
    https://en.wikipedia.org/wiki/Carbonaceous_sulfur_hydride
    "...The chemical formula is possibly CSH8 ...."
    I am a bit surprised by that above "possibly"; I would have thought they would have at least determined the ratios of the chemical elements it is made of.
