  • I had a CT scan after an accident, and no one told me what contrast is going to feel like, the nurse simply injected me without any explanation.

    And omfg, that might’ve been one of the scariest 30 seconds of my life. It felt like I was injected with straight up lava. My whole body was burning from the inside, and I felt like I would just spontaneously combust any second. It very quickly subsided though and there was no negative reaction overall, just higher sensitivity than average. But holy shit, I would want to know about stuff like this beforehand.






  • You know scientists always trying to make things happen but never asking if they “Should”?

    I’ve never seen someone use this as an argument, only as a joke. Can you provide some examples of the things that you think scientists tried to make happen without thinking whether they should or not?

    Also, how is user-specific trust at play here? I never even look at usernames, instead I will upvote or ignore posts based on their content. I don’t think you can really ease Lemmy/kbin users into believing some divisive nonsense that easily.







  • So I read the paper. Here’s a tldr about how their material apparently gains its properties.

    It is hypothesized that superconductivity properties emerge from very specific strains induced in the material. Hence why most of the discovered superconductors require either to be cooled down to very low temperatures, or to be under high pressure. Both shrink the material.

    What this paper claims is that they have achieved a similar effect chemically by replacing some lead ions with copper ions, which are a bit smaller (87 pm for Cu vs 133 pm for Pb). This shrinks the material by 0.48%, and that added strain induces superconductivity. This is why it apparently works at room temperature — you no longer need high pressures or extreme cold to create the needed deformation.

    Can’t really comment on how actually feasible or long-lasting this effect is, but it looks surprisingly promising. At least as a starting point for future experiments. Can’t wait for other labs’ reproduction attempts. If it turns out to be true, this is an extremely important and world-changing discovery.

    Fingers crossed :)
