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.
I’m most excited for fusion power generation. Currently we can ignite a fusion reaction but it takes more energy to control and contain it than you get back because it takes a huge amount of electricity to generate a magnetic field strong enough to contain the plasma. The strength of the magnetic field is proportional to the current flow, which is limited by how much cooling is required to maintain superconductivity. Without cooling taking a huge chunk of the power created by the fusion reaction we could net positive energy from the reaction and finally have a clean source of scalable nuclear power.
Long-distance energy transfer without energy loss will make it possible to connect more energy grids and sources together, so stuff like the saharan desert providing solar power to Europe, for example, suddenly becomes feasible. Maglev trains will no longer require lots of power to run, since they could utilize superconductor magnetic levitation. You could make super-efficient processors that wouldn’t really heat up at all. Superconductors are also key to quantum computers, so expect lots of advancements in that field as well. They will also make it much easier to build and run fusion power experiments.
Lots of tech in general would benefit from this discovery, stuff like MRIs, electric vehicles, space telescopes or particle accelerators would become way more efficient, cheaper and easier to produce.
Edit: also, check out this video by Isaac Arthur for some more sci-fi examples of what this tech can be used for in the future (discussed in the second half). It’s more space-colonization-focused and kinda like a thought experiment, but interesting nonetheless.
Not really. If that turns out to be true (nothing is guaranteed yet), the processes described are pretty straightforward and don’t require any super-advanced tech to be reproduced. Full-scale production could be rolled out in mere years. That would become beneficial for stuff like MRIs or electric cars as soon as production starts.
After that, my guess would be that some large-scale energy infrastructure projects, for example, could be completed in about a decade.
Does this get us hovering without rails? Could we theoretically generate a magnetic field strong enough to repulse the earth? Or is that still Science Fiction?
You still need a magnet-superconductor pair for quantum locking and magnetic levitation. This is called the Meissner effect and it seems like it has been confirmed for this material. Here’s a video showing an example of such a system.
Before, the best way to scale this up might’ve been to make permanent magnet rails and run a superconductor train along those rails, but that would have been totally infeasible and inapplicable in real life, since building rails out of permanent magnets is expensive and dangerous, and the train would need to house a really large superconductor chilled to liquid nitrogen temperatures. You couldn’t have built a track out of superconductors irl because good luck keeping those at the temperatures required for superconductivity to kick in.
If this material turns out to actually work as claimed and to be producible at scale, you can switch those and make an electromagnetic train that travels along superconductor tracks. Which is way easier, cheaper and much more doable in general.
But the earth’s magnetic field is extremely weak, and even the tiniest pieces of superconductors are unable to lock with it. So no, it does not allow for trackless levitation.
But a cool new train system design becomes possible though!
You're right, haven't heard about that one. They actually do use superconducting magnets on a train that runs along a magnetic track.
But I feel like my feasibility comment still stands. It seems like all they had built is a 18km test track, and there's some info about extending it to 48 km, but it doesn't seem like the extended part uses superconducting tech yet, it only mentions regular maglev. The Tokyo — Osaka line is planned for 2037. So yeah, its technically possible, but it's not like you can cover Europe or the US with this type of track for any sensible amount of money.
That's the cool part about room temperature superconductors, they make this type of tech possible on much larger scales.
It sounds like the full line will eventually go across most of Japan and operate in the same way as the test track, however it is expected to be very expensive, and room temperature superconductors would likely lower the cost.
Superconducting materials will expel an induced magnetic field as it creates internal fields that exactly cancel out the induced one. You’d still need some sort of “rails” to created the induced field and to move it to generate forward motion.
That is for the Meissner effect I think. I guess what I was thinking is to use the SC to create an incrediblely strong electromagnet to repel the Earth’s magnetic field. But it looks like we are orders of magnitude away from that
If they can be made into wires (or close to them) you can create things like lossless electricity transmission, lossless batteries, electronics without heat generation (or very low), etc. Transmission lines would likely still need some sort of cooling but at room temp it would be a lot less than for the current superconductors that require at least liquid nitrogen.
What kind of magnetic fields would be induced with superconducting wires/rails carrying an AC current? Or is there even any reason to use AC with superconductive transmission?
Those ultra fast and efficient trains required superconducting rails IIRC (which I think indicates strong magnetic field because they used magnets to levitate so that the only friction involved came from air). I wonder if we could combine the trains with transmission and basically have trains that use the power mains to get from A to B.
If we had a practical room temperature/pressure superconductor its kind of hard to overstate how amazing that would be. Its the kind of thing that normally gets put in the same category as faster than light travel in terms of all the amazing stuff you could do with it.
Not thrilled that it is a lead alloy. Just when we are starting to get rid of all the lead in our communities, this would put it back as part of critical infrastructure everywhere…
The transition to lead free solder (and lack of experience using it) led to the XBox 360 red ring of death issues, Playstation 3 yellow light of death, and nVidia 8000 series no video failures.
And indeed the transition happened a long time ago.
As others have mentioned lead is still everywhere. All our combustion car batteries are still lead/acid batteries, but if what /u/[email protected] mentioned the paper claims is true, the method for inducing superconductivity in the metal could possibly be used to create other lead free ones.
Interesting and it wouldn’t be a ceramic. Downside is that it is lead based. Not exactly good for the environment or very flexible without breaking. Lead doesn’t make good wire.
A lot of people were wondering this during the later Trump years: what’s to stop government officials from simply ignoring the Supreme Court (or another branch, for that matter). It’s surely a “Constitutional Crisis”, but many conservatives seem more interested in preaching about the Constitution than actually following it.
what’s to stop government officials from simply ignoring the Supreme Court
A federal government being willing to enforce the law Reconstruction style and send in federal troops to effect the arrest of these traitors and the unconditional surrender of their government. Anything less is just giving the anti-democratic forces time to get stronger and chip away at more of our society.

At first I was writing a comment to say the Posse Comitatus Act wouldn't allow this, but it seems like the Insurrection Act of 1807 is an exception, and would apply in this instance.
The President, by using the militia or the armed forces, or both, or by any other means, shall take such measures as he considers necessary to suppress, in a State, any insurrection, domestic violence, unlawful combination, or conspiracy, if it—
(1)so hinders the execution of the laws of that State, and of the United States within the State, that any part or class of its people is deprived of a right, privilege, immunity, or protection named in the Constitution and secured by law, and the constituted authorities of that State are unable, fail, or refuse to protect that right, privilege, or immunity, or to give that protection; or
(2)opposes or obstructs the execution of the laws of the United States or impedes the course of justice under those laws.
In any situation covered by clause (1), the State shall be considered to have denied the equal protection of the laws secured by the Constitution.
Edit: I feel compelled to point out that we're not here yet, because the SCOTUS order has a review process for the new voting maps, and if a judge rejects them, the judge can authorize a third party to draw the maps for Alabama. If the Alabama government rejects those third-party maps, then shit gets real.
It won’t get that real. Ohio’s GOP has been ordered by our state Supreme Court since before 2016 to redraw fair voting maps and not only did they not, but they submitted blatantly unfair maps that didn’t even come close to their guidelines. The Court has done nothing and will continue to do nothing.
We are most certainly within a constitutional crisis. You can probably start the timeline at the 2000 Supreme Court ruling where the court said it had no authority to rule, but it did. The republicans blocking the supreme court nomination was also a clear breakdown of the system.
I feel like a lot of these people are unprepared for the civil war they claim to want
When you live your whole life in a cushy environment with more competent people than you making sure that the lights stay on and the food keeps coming, it’s easy to have this weird fantasy that you are God’s chosen person and you can wander around believing and doing whatever you want. Just looking at this woman’s face, though, I feel like she would be the first to abandon her convictions and say yes judge I’ll do whatever you want once the cell door swings closed for real. Maybe I am wrong but that is the feeling I get from looking at her.
You’re probably right. But the MAGAsphere is going to wring a few more clicks out of her before she’s discarded. And she can’t wait to help them do it.
Well based on what the article states, it says she “expressing unhappiness and saying she wanted to leave home.” Which can mean alot of things, she could have a terrible home life, undiagnosed depression, been coerced into that line of thought by the man or even something else.
We’ll have to wait for more information to co.e to any real conclusion. At least she was safe. That’s what truly matters.
Stomach isn’t enough. If you’re not actively campaigning and donating for her–or whomever the candidate is–then you may as well have been a Republican.
EDIT: Nevermind. Clearly the hivemind wants to stay in our armchairs. Who can blame us, right? We’ll continue this conversation in November. I hope it’s not I-told-you-so.
Squid, I appreciate your contributions to putting content on the platform, honestly, but I couldn’t be any less interested in that take. My history speaks for itself, and anybody can read it who cares to. Everybody must vote. I don’t think I could be any clearer about that. I was a staunch advocate for Biden, and I’ll be a staunch advocate for Harris, Newsom, Whitmer, or anyone else who carries the Democratic party forward.
But every single one of them polls down from Biden. To the extent any of the whining on social media since the debate hasn’t been astroturfed, advocacy for Biden to drop out resulted in this news, and it means that the party has now voluntarily given up the single biggest proven advantage a candidate historically has in a presidential election: being the sitting president.
I’m encouraging people to vote, but you know as well as I do that people who were going to vote anything-blue were going to vote for Biden no matter what anybody said on almost-reddit. Harris has to move the needle further than that, and that means that all the armchair it’ll-be-better-if-he-drops-out analysts now need to step the fuck up if they want this news to mean anything other than “The DNC just handed Trump 2024.”
Everybody knows that the kids screaming “oh if the candidate were just younger, the Dems would have it in a landslide” were full of shit, and now we’re about to see just how big a deficit we’re actually running. I’d love to be wrong! I’d be delighted, ecstatic, beside myself to discover that next weeks polls put all these convention front-runners up 10 points on Trump. But I’ve studied this stuff, and it doesn’t take a veteran pollster to realize it doesn’t work that way. Actual campaigning has to happen.
If you cared enough to want Biden out, but not quite enough to want Harris to win, then you were going to hold your nose in the ballot box either way and it doesn’t fucking matter: Trump would still win. That’s not discouraging. That’s statistics.
Telling people that if they don’t go out and campaign, they might as well be a Republican is just counterproductive. Insulting people is just never a way to get them to do what you think they should do.
I don’t know why so many people think that’s the right tack. Have you ever been insulted into doing something?
You know, Squid. You’re right. This whole time I’ve been venting because I feel like we’ve been completely outplayed by astroturfing foreign propagandists and bots, and it feels like I’m the only one who realizes it. This stuff has real, serious consequences for real people–but why would I expect a bunch of NEETs and children to get that?
Everybody who swallowed it still genuinely thinks they won something, so I guess it’s not fair to lash out. I don’t really want to get anyone on my side because my side doesn’t exist here anymore.
I have to thank you for finally getting me off the platform. It’s just not worth it.
It’s all a huge conspiracy by foreign propagandists to… replace Joe Biden? Why? And this conspiracy either fooled or forced DNC wonks to pressure Biden to drop his campaign, and this propaganda… originating from foreign sources that you but not they can see, caused Biden to concede.
Look dawg i know someone saying take a breath on the Internet has the opposite effect but for real, maybe you need to take a step back right now and take another look
Any moment now, the ‘don’t vote for Biden’ group will be in here telling us not to vote for Harris. And if it isn’t Harris, they’ll tell us not to vote for whoever it is.
Anything but stop the dictator and his plan to commit genocide against Latinos and queer people.
Then why are you insulting people here by making up a strawman argument and insinuating that the people who don’t support unpopular candidates are somehow rooting for Trump? This is like the DNC’s 2016 arrogance all over again and look how that turned out for the country.
It’s still not a strawman argument that people who were posting all over Lemmy that no one should vote for Biden are now posting in this very thread that people shouldn’t vote for Harris either.
Also, I’m not trying to get people who aren’t planning on voting for Harris to campaign for Harris. That would be silly. So I have no problem with anything that I said.
In the countless posts leading up to Biden dropping out, people were saying the same thing about Harris then too. Trading one bad candidate for another isn’t what anybody asked for, so you’ll have to explain how these people you speak of should now be satisfied and stop sounding the alarm.
It seems there are too many people who would rather kowtow to the DNC leadership’s desires than actually prevent Trump from getting elected again after the DNC failed us in the exact same way in 2016 and nearly again in 2020. What will it take for them to wake up? People demand unity within the party, but for some inexplicable reason, they always demand that we unite around their unlikable right-wing candidate.
It seems to me that the way to actually prevent Trump from getting elected again is to vote for his opponent and not to keep telling people not to do that for whatever reason.
With people like you it shows why Trump won culturally even if he doesn’t win the election. He turned a substantial part of the vocal Democrats into Blue-MAGA-hats. It is the same attitude that attacked people who pointed out the mere fact, that Biden is not mentally fit for office anymore. If the Blue-MAGA wasn’t so big, Biden could have left the field to a younger and better candidate half a year ago.
So you think calling everyone that does not campaign and donate to the Democrats a secret Republican is somehow normal?
To me it is the same cultish bullshit like the blatant denial of Bidens old age and mental decline. It is the same “follow your leader no matter what” insanity that is apologetic for Trump on the other side. So yes, this kind of behaviour is MAGA behaviour and if it is done for the Dems instead of the Reps it is blue MAGA
The “hive mind” probably just can’t figure out what the fuck you’re even trying to say. So, what, everybody who doesn’t actively campaign for their preferred candidate just supports fascism by default? I’m guessing your stance isn’t anywhere near that stupid, because that is an extraordinarily stupid stance. So maybe you’d have a better reception if you clarified your point.
Absolutely not. I will spend my time and energy and money supporting my local Democrats. The national level isn’t as important to me because Republicans in my state have veto-proof majorities in both houses and they hold the governorship. Regardless of what happens at the national level, implementation of Project 2025 began in my state about 3 years ago.
You couldn’t browbeat us into voting for Biden and you’ve started it right up with Harris? And now it’s not just voting it’s working the phones and door to door campaign? Am I expected to get airfare to PA too? What do I tell them when they ask where I live?
People should support her campaign to the utmost they can, and for some people that’s right here, with their internet connection.
I was vocally saying biden would never drop out and we just had to swallow the poison pill. I was dead wrong. I will be voting for [insert DNC candidate] and will be excited to do it!
While I don’t think Kamala is the best the Democratic party has to offer (I would have much preferred Biden endorsing Hakeem Jeffries, for example), I’m over the moon that he’s finally decided to step aside. And you know what? Harris is better than Biden in pretty much every metric that matters. I was going to vote for the Dem nominee either way, but him stepping aside in favor of a better candidate has me feeling all kinds of relieved.
It feels like the novelty of an attempted XPOTUS assassination wore off in less than 48 hours. That’s crazy.
Nobody around me is even talking about this anymore - not at work, not on social, not at the grocery store, nowhere.
Idk if that’s due to everyone being super jaded or because it’s Trump. If it’s because it’s him, then I wonder if it’s because nobody gives a shit about him or if it’s just not surprising someone would take a shot at him or just because it’s irrelevant to his candidacy or what else.
Especially the right. If this kid had a little more left in him they’d never stop. Introspection about the normalization of political violence among conservatives is not something they’re interested in.
I mean, they’re not going to stop regardless – they’ll be blatantly lying about the assassination’s motivations to smear the left until the election and beyond. Still, from an election strategy point of view, that’s definitely better than them being able to make “both sides” claims that are true.
I actually have a different perspective on it, I think people stopped caring because it was a shooting where “only” 1 person was killed. Gun violence is so normalized that the only 2 reasons it got any coverage at all is because of the timing and the target.
Yea, it’s a pretty dark realization. I don’t feel bad for Trump. I feel bad for every single gun death that has occurred leading to this incident being a minor footnote.
The same week that Jamar Clark, there was a mass shooting at the warehouse district blue line stop. 3-4 people died with a few more shot.
Jamar was shot by cops. The others were shot in a gang dispute (the victims were not associated, but mostly black, the shooter was black, iirc,)
You won’t find the names of the victims anywhere online.
Also, before Sound Bar closed down, there were weekly gang fights spilling out of the joint, into the streets/lot out back.
People were shot monthly with a string of deaths for about 2-3 years.
Then a C-tier Vikings player got winged and suddenly they yeeted the liquor license.
We’re absolutely desensitized and the only time we know about a stranger getting shot is because there was something about the case- killed by cops, the shooter was famous, the victim was famous, or it was some kid, or it was in the context of a mass murder and nothing else was going on.
Mannnnn flashback to me working valet at sound bar the night of their last shooting. Heard them pops inside the joint and we all book. Ladies spilling out the door tripping over each other. Goofy fucking night
Well, even if he was wearing one over the weekend, it’d have to be one of the discreet ones that go under your clothes. I don’t think those are actually rated for stopping rifles, and I definitely wouldn’t trust someone of his age and health to not seriously get fucked up even if it did.
I feel like this is just the state of America now. When everyone was freaking out that this was the downfall of the election yadda yadda… I was just thinking to myself “this is the country where kids get slaughtered in school and we’re sad for like 2 days… I give this a week at most”
I get your point, but damn I’d love to have a Powerball ticket that was off by one number. That’s more than enough money to retire on. Not that I need it, it’d just be nice to retire at 43 rather than 49.
Really? I was at the gym yesterday and they couldn’t stop framing things with the assassination attempt. “Two days after assassination attempt, day two of the RNC.”
Like, that was literally the chyron on CNN. Yesterday evening.
Yes, really! I thought you might find the post I’m linking above interesting. It was at the top of my feed this morning and may be relevant here.
I am curious if maybe you were witnessing people of the Boomer generation (or older GenX) discussing this because they are more likely to be consuming mainstream broadcast news?
Maybe I’m crazy here but if I saw a dude with a rifle on a roof at a political rally I would 100% assume it was secret service. I don’t see much here that convinces me otherwise
Edit: there is some evidence that he may have been on a roof. It’s hard to get accurate information this soon after an incident so we’ll see in the coming days
Edit: yeah, pretty much confirmed it was the gunman, assuming this guy is talking about the right roof (secret service were on a different roof). I still stand by my original comment, I wouldn’t have thought anything of it if I saw it
And if you saw him getting into position mid speech that wouldn’t strike you as odd? The shooter was seen low crawling into position. Secret Service shooters would be in place from the start not moving mid speech.
If they were in legit gear or a suit, I wouldn’t think it was odd. Any other guy with a rifle would be a red fucking flag because plainclothes USSS have concealed guns and don’t play on roofs.
No. USSS Snipers are all over the place. Some visible most are not. In one of the videos you can clearly see a USSS sniper above stage right. That’s the guy who took out the shooter.
Yeah, I think that that’s been normal for a long time. There are even pictures of the law enforcement on a rooftop at this rally with scoped rifles.
EDIT: One of the top posts on Reddit says that this is the shooter after having been shot. Assuming that is correct, gives an idea as to what he was wearing.
That kind of uncertainty about if the shooter was part of the security detail or not may have been the source of hesitation that let him get shots off before immediately getting shot himself. The speed of the return fire makes it seem like someone was already pointing a gun at him and awaiting confirmation he wasn’t supposed to be there.
Agreed. It’s going to further inflame chaos and tensions in the country, it’s going to further radicalize Trump himself into an even nastier man, and it’s going to motivate his base. Even if Trump were to pass away, that base still remains, and we have the risk of a much more intelligent and gifted speaker taking up its leadership.
If it were anyone else, almost getting shot should be a wake-up call. “What have I become that this happens? Maybe I need to change how I act, and what I do.” But , no.
There have been many failed and successful assassinations of political leaders or other public people. You think if John Lennon had survived his assassination he should have taken it as a wake-up call and revisit his values and public stances?
There is many good reasons why Trump should start introspecting. And if he would develop some sort of empathy and decency probably the pain of seeing who he was and is would kill him better than any bullet could.
But this is because he is Trump. This is not because someone wanted to kill him. All sorts of people want to kill all sorts of people for all sorts of reason.
True, it was always never going to lead to good things. But this will keep it on track to not changing.
I just hope Trump pusses out when he realizes he and a bunch of supreme court justices are foing to get this for nearly every public appearance for four years if he manages to eek out a win lol. It was said above already.
Violence demands self defense. Today was an act to try and save everyone.
Meta said it had a responsibility to allow political expression and that Americans should be able to hear from presidential nominees on an equal basis.
Meta said fascists should have their voices heard. Zuck’s a coward, what a fucking surprise.
E: though tbf it wouldn’t surprise me one bit if he’s letting trump back on the platform because he wouldn’t mind him winning. After all, trump is good for billionaires, there’s no question about that…
I mean…at the very least it’s consistant. I never had an issue with Bill Clinton getting a BJ. I felt like Hillary should have the right to be mad, but everyone else should fuck off.
The right on the other hand lost their shit. They made it into a 4 year big deal. If Bill had just told the truth on the stand, that he got sucked off and loved it, then they’d have no tools to impeach him. But to them the sexual deviancy was the big deal to them.
I guess same here. They don’t care about laws or the country, but if you include sexual misdoings, they faint like a karen in a church seeing people outside having fun.
Like stormy. He doesn’t say he didn’t pay the media to influence an election. Apparently he thinks that part was ok. He throws a fit saying he didn’t have sex with her.
That’s just a facade they put up in public. Newt Gingrich lead the charge on that impeachment and at the time was cheating on his wife (later to deliver her divorce papers at the hospital where she was receiving cancer treatments and leaving her and their children completely broke).
Furthermore, you can look at all the scandals with organizations like the Boy Scouts of America or the Catholic church and they still get unwavering support from the right.
They always denied it was about the sex though. Even at the time. We all knew it was, but they constantly were claiming it was about lying on the stand.
And then Larry Flynt inadvertently helped them on that front when trying to shame them by putting out a report detailing all the Republican congresspeople who had affairs. I appreciate what he tried to do, but that made it even easier for them to say it wasn’t about the sex since no one got rid of them for an affair.
It was about the letter after his name. If sex was illegal (and I think sex with subordinates often should be), they would have gone for that. Lying under oath is illegal, so they went for that. This wasn’t some principled mission, this was to stop the guy they disagreed with using whatever would stick.
Until these assholes stop taking in record profits each year & their ceos get more money than some countries generate they can fuck off on saying wages are a problem. The working poor deserve every penny they can get.
Agree. None of these CEOs have any groundbreaking ideas either. It’s all the same strategies for short term profits rather than longer sustainable growth.
That’s just it, as a business owner, some years may be good, and some years may be bad.
So some years your profit should be less.
That doesn’t mean you’re going under. Less profit is still profit. That means everyone (including yourself) has been paid and you have money left over.
But because CEOs are paid mostly in stock, the profits have to rise every year, for no necessary reason besides “I like money”
And eventually that’ll break, and it’ll happen all at once.
