Test reproduced by independent labs and there is absolutely no superconductivity at room temperature. They most definitely did NOT get it this time.

- I really wanted this to be real. Ughmonospaced
- Still do!monospaced
- Who are you science boy?grafician
- excuse me?monospaced
- in the link from sted, a bunch of the labs had partial success, so something is happening or they are close_niko
- Yupmonospaced
- one independent lab.
also if it works, industry labs are already thinking about and developing implemantations.uan - We’ll see but the fact that it hasn’t been absolutely confirmed despite the worlds top labs working on it constantly for weeks is very worrying.monospaced
- In fact, there’s little to back up the claim at all, that’s verified. Nothing to confirm the claim in any way sadly.monospaced
- except 2 theoretical calculations that claim it could work.
https://www.science.…uan - blog post is old (2weeks), but I want to read his next update before I jump to conclusions:-)uan
- it’s now 2 months old and still no confirmationmonospaced
- https://www.science.… 2 possible explanation according to this update.uan
- 1) entire initial report was bungled
2) Authors are about a patent for creation of material. he links a patent application in Korean.uan - Thanks for that. Even the author agrees that there’s almost no likelihood whatsoever that it’s anything but a bullshit study and claim.monospaced

- The issue with many replication experiments is that they don't follow the original "recipe" as it's not straightforward
But overall, it seems we finally got itgrafician - Most of these labs are following it and not able to reproduce with success. How do you know they aren’t doing it right? Really?monospaced

"National Lab (LBNL) results support LK-99 as a room-temperature ambient-pressure superconductor."
"Simulations published 1 hour ago on arxiv support LK-99 as the holy grail of modern material science and applied physics.
(arxiv.org/abs/2307.16892)Here's the plain-english explanation:
- The simulations modeled what the original Korean authors proposed was happening to their material - where copper atoms were percolating into a crystal structure and replacing lead atoms, causing the crystal to strain slightly and contract by 0.5%. This unique structure was proposed to allow this amazing property.- @sineatrix from Lawrence Berkeley National Lab simulated this using heavy-duty compute power from the Department of Energy, and looked to see what would happen to the 'electronic structure' of this material, meaning, what are the available conduction pathways in the material.
- It turns out that there are conduction pathways for electrons that are in just the right conditions and places that would enable them to 'superconduct'. More specifically, they were close to the 'Fermi Surface' which is like the sea-level of electrical energy, as in '0 ft above sea-level.' It's believed currently that the more conduction pathways close to the Fermi surface, the higher the temperature you can superconduct at (An analogy might be how its easier for planes to fly close to the surface of the ocean due to the 'ground effect' that gives them more lift.)
This plot in particular shows the 'bands', or electron pathways, crossing above and below the Fermi surface.
- Lastly, these interesting conduction pathways only form when the copper atom percolates into the less likely location in the crystal lattice, or the 'higher energy' binding site. This means the material would be difficult to synthesize since only a small fraction of crystal gets its copper in just the right location.
This is insanely bullish for humanity."

Today might have seen the biggest physics discovery of my lifetime. I don't think people fully grasp the implications of an ambient temperature / pressure superconductor. Here's how it could totally change our lives.
1. 100 billion kWh of electricity are wasted on transmission losses each year in the US alone. That's equivalent to 3 of our largest nuclear reactors running 24/7. Superconductivity enables lossless electricity transmission at high voltages and currents.
2. According to the authors, the LK-99 material can be prepared in about 34 hrs with extremely basic lab equipment (a mortar & pestle, basic vacuum, and furnace). These results could replicate within days-weeks.
3. Nuclear fusion reactors rely on superconductors for plasma confinement. Modern designs use RBCO/YBCO superconductors cooled with LN2 or Liquid He, creating a huge temperature gradient and challenging operation. Ambient superconductors enable a whole host of new reactor designs
4. Quantum computers use superconductors to preserve coherence in qubits. Small changes in temperature and pressure can cause the entire QC to fail during operation. Imagine a room temperature quantum computer on your desktop - now possible.
5. Superconductors might be the best batteries out there. Simply inject a current and keep it in the coil until you need it. Previously, too costly to maintain. Now, totally feasible.
6. Your iPhone won't overheat when playing subway surfer with a youtube video in the corner anymore! Ultra-efficient computer chips will have 0 resistive losses during operation with superconductors. No need for cooling fans!!
7. And, the common ones: super-cheap MRI machines, MagLev trains everywhere, and a super efficient electric grid.
8/8 I cannot contain my excitement. It feels like January of 2020 with a huge wave coming that no one realizes yet, but in a much better way. What a time to be alive!!
- Awesome. Further support that science is not, in fact, a belief system ;)monospaced
- Confirmed

This is going to be a black swan event, only gooddrgs - I’ve seen conflicting results that do not confirm it.monospaced
- There is still hope, the original study was poorly documented, or at least it opens up a new direction in physics which eventually will get us theredrgs

Something Was Messing With Earth’s Axis.
The Answer Has to Do With Us.
Water experts have long warned of the consequences of groundwater overuse, particularly as water from underground aquifers becomes an increasingly vital resource in drought-stressed areas like the American West. When water is pumped out of the ground but not replenished, the land can sink, damaging homes and infrastructure and also shrinking the amount of underground space that can hold water thereafter.

Humans actually possess a protein (cryptochromes) needed for the detection of magnetic fields which they could theoretically sense, but it seems that our brain doesn't seem to have any way to decode this information
- maybe they didn't discover it yet...I recall a reading Aboriginals in Australia are known to always know where N,S,W,E is.uan
- they greet each other in the middle of the desert by saying which direction they are coming from. this might train / develop that capability from small age on.uan

Hidden Brain had an episode on it.

It can be learned, I guess they're consistently keeping track at a low level.palimpsest - could also just be we know east/ west on sunrise/set and somehow our brains process the tweening in the background during the day:)uan

You may have thought you were progressive but are you really compared to this?
"The Radical Plan To Phase Out Earth's Predatory Species"
The Hedonistic Imperative outlines how genetic engineering and nanotechnology will abolish suffering in all sentient life.

More evolution facts insipired by shapesalad.
Herbivorous animals actually need twice as much sleep as carnivores, because they have to spend half of their sleeping time keeping watch with one eye open. That's why you'll often see cows and other herbivores napping during the day - they're catching up on all the sleep they missed while keeping an eye out for danger at night!
They need extra time to dream up new ways to outsmart carnivores who are always trying to catch them for dinner.- It's also why their mating lasts mere seconds as it's a vulnerable time when a predator could potentially get a 2 for 1 lunch option.shapesalad

- "It’s a very strong theory that cooking was one of the direct causes of our punctuated evolution as a species."palimpsest
- yawn, I know you’re just baiting me, but I’ll bite. There are different meanings to the word theory and we are using both. You know this.monospaced
- And our species evolving into modern humans isn’t THE theory of evolution. Don’t conflate them.monospaced
- I hope someone as scientifically literate as yourself sees why claiming that any behaviour in a species is a by-product of evolution is unnecessary and stupid.palimpsest
- And the use of punctuated as an adjective in our evolution just went over my head. Please educate me.palimpsest
- Daddy.palimpsest
- Since we're being petty. There is a single theory OF evolution. But one can propose multiple theories ON evolution.palimpsest

Me and shape were having fun until you came in with your dumb "Science isn’t a belief system." out of nowhere comment.palimpsest - Now the light's on you.
So go on and educate us.palimpsest - Plays on words, double-entendres, and banter all just sail right over your head, don't they, mono? I've never seen anyone take things so literally as you.Continuity
