Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.
Research paper: https://arxiv.org/abs/2307.12008
I'm gonna go out on a limb and say that until this is peer-reviewed and replicated, this is worthless.
I'll also gladly eat my shorts if it turns out they actually did it but ATM I'm very skeptical.
I do hope they are right I would love see you eat your shorts.
Just a word of caution: Non-peer reviewed, non-replicated, rushed-looking preprint, on a topic with a long history of controversy and retractions. So don't get too excited yet.
This is huge, is it not? No loss in potential energy means that I could have an infinitely floating coffee cup without the use of power, no?
What's the purpose of posting these results before they have been peer reviewed and reproduced?
Because this is how they get peer reviewed and reproduced? Publishing is how science works?
Publishing this outside of a reputable journal is definitely not how papers get peer reviewed. In fact, its a huge red flag.
This is a preprint published on arXiv.org, which is as reputable as it gets before peer review (so no red flag but standard practice). But I agree that people shouldn't place hopes in this before it's been peer reviewed and replicated by independent researchers.
My comment was directed specifically at the parent's comment about publishing (in general not in a reputable peer reviewed journal which arxiv isnt) being how peer review happens. Arxiv is a preprint server. There is no peer review and while many of the papers there have survived the peer review process, a paper being on that server doesnt really say anything about the quality of that paper. It could be a great paper, it could be garbage or somewhere in between the two extremes. In any case, the hype around this paper is concerning because it has not, as of yet, survived the scrutiny that is demanded by the claims it is making.
Reposting my comment from another thread to add a bit of context in case anyone’s curious.
So I read the paper, and 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 pressures. 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.
Room temperatur 127?? You fucking kidding me?
