So, these folks replicated the material and it does highly unusual things, is that right ? It had seemed the fabrication process was still very dodgy and unreliable, this team got it to work independently?

My layman understanding is that this paper states the team replicated LK-99, and confirmed that it has a property of a super-conductor - this particular type of magnetic levitation.

What is interesting is that assuming it all pans out these are all in entirely unrelated fields. That sets the stage for a whole raft of follow on inventions. Similar to how the telephone + basic electromagnetism led to radio, tv, radar, transistors and ultimately to computers small enough to be practical for businesses, the internet, cell phones and so on. My grandmother was born in a house without running water, no…

Yeah - I think the next 40 years are going to be absolutely stunning to witness. It’s an amazing time to be alive and be a nerd.

The last 20 are already mindblowing to me, to the point that I am a bit overwhelmed. Just reading to keep up with all of the tech developments is basically impossible today.

This makes me so happy for my children and their children. God bless those scientists and all scientists that push our species forward. I'm so lucky to be in my prime at the same time AGI and superconductors become a reality. Wow.

> AGI Wait, I missed that one. Was it yesterday?

yes

On a completely different front, let's say the paper completely checks out and they have discovered this miracle. How strong are the patent protections on materials science? For example, if someone could replicate the effect with lead + gold, would that be considered a novel material which would not be subject to licensing? Is it the material itself or the method of production?

I hope they're as weak as possible. The worst possible outcome of a room temp superconductor being discovered is stifling innovation to make money off it

i wonder if this will become the next version of hopium, where we struggle to refine a material that can actually be used in a wide enough temperature range to operate outside.

The initial paper claimed superconductivity up until 400 K (127 °C or 260 °F), so I think if that's the case it would be able to withstand outdoor conditions just fine

It’s a breath of fresh air reading about actual revolutionary science happening. The deluge of news about non-replicable results, fabricated data, overhyped press releases from both academia and industry had become really depressing. For once after a long time it’s the real deal. Even if this is not a RT superconductor, it’s now evident that the original authors didn’t cheat and are not crackpots as initially suspect…

You know, most of that stuff you hear about are bad takes on science. Science has moved into the realm of trying to understand complex systems with a lot of noise and with unknown variables. There will be a lot of misses; but that is how sausage gets made.

I'm sure it depends on jurisdiction, but in the US, you can't patent a material, only a method to make it. If I recall correctly, their patent for method covered a wide range of constituent elements, but left off gold. I would feel pretty bad for them if they genuinely discovered an RTP superconductor but that omission prevents them from becoming billionaires. But more likely the issue is that their current method ha…

> in the US, you can't patent a material I'm no patent lawyer, but there is literally a US patent-office category covering "material" for exactly this kind of invention. Section 505 - "Superconductor Technology: Apparatus, Material, Process". > This is the generic class for subject matter involving (a) superconductor technology above 30 K and (b) Art collections involving superconductor technology. Apparatus, devices…

Yeah, apparently wrong. Not a lawyer, obviously, recovering physicist/current SWE.

Noob question. Does this breakthrough also translate to advancements in quantum computing? Can we expect quantum computers with far more qbits?

Nope. Quantum computing requires low temperatures not because of resistance but to maintain coherence.

Im posting this reply from my mainstream smartphone: a pocket supercomputer with a 4K 60Hz HDR video camera. I’m chock full of designer vaccines and can watch a catalog of almost all the movies ever made on demand tonight. I listened to an podcast in my EV on the way to work. And SpaceX probably launched 60 satellites this week on the 14th flight of a rocket that flew home afterwards. Things have been moving along. e…

And it’s only going to get faster… unless it all ends suddenly.

I feel we will eventually outpace our own means of destruction. The next big step is getting self-sustaining colonies off Earth, which will do wonders for our ability to survive as a species. The biggest threat is perhaps nuclear weapons and climate change, in my opinion.
