So far lab replication efforts are: Two from HUST: https://www.bilibili.com/video/BV14p4y1V7kS/ https://www.bilibili.com/video/BV13k4y1G7i1/ One by USTC https://www.bilibili.com/video/BV1Ex4y1X7ix/ this tiny sample can stand on its pointy side. One by Qufu Normal University https://www.zhihu.com/zvideo/1669820225079070720 One with THU background but claims a personal project https://www.bilibili.com/video/BV14z4y1s7V…

> Why are't more labs outside China making LK-99 and publish videos? some possibilities: - they have not been able to conclusively replicate anything and don't want to publish a negative result for fear of someone else publishing a conclusive positive result later. - they are more careful to publish something that they are not (yet?) 100% sure about - they don't care so much about the whole 'science in the spotlight'…

To add to your list of possible reasons:

- There are way more STEM graduates in China by a wide margin

- 18/20 of top universities in the world for chemistry research is in China according to Nature, including one of the attempts by USTC (#2 ranking): https://www.nature.com/nature-index/institution-outputs/gene...

- Supply chain is faster in China for chemicals and materials

- China has more money/equipment for this sort of stuff

- China is on average, more pro-science than the rest of the world

I am from China. Not surprised at all.. Young researchers in China often face intense competition and pressure. While they are generally well-funded in the short-term, even more so than their counterparts in the US or Europe, the lack of long-term career security can be challenging. They must continuously chase after every potential scientific breakthrough, like LK-99, not just out of passion or curiosity, but as a n…

Would this lead to rushed results? Or it's worse to give bad results than no results?

Yes, as you have seen this time.

For those experiencing this type of "black swan, but good" event for the first time, it is helpful to recognize that the human tendency to believe that all future "big events" will be dystopian downers, is statistically unsound. For a while I've kept a list of the things that could be "good" swan events, but to be fair I didn't have "room temperature superconductor on that list" :-) Other things that could happen: 1)…

4) useful bipedal robots - this one is probably just around the corner (see boston robotics). We often talk about how much AGI could benefit humanity, giving knowledge workers a digital "team" of helpers, but we gloss over the physical version. Everything from dangerous industries all the way through health services and into retail could be enhanced by having robots do all the literal heavy lifting.

5) programmable matter / nanobots - the applications of a swarm of nanobots or even microbots are pretty much endless.

It's likely we will be able to grow full working organs, tissues and limbs in a lab before we can reanimate frozen bodies. So wouldn't be more efficient to cryopreserve only the brain?

Are you in the wrong thread?

Sorry to piss on your sunny parade, but: >> 1) Fully decoding the cellular mechanism of cells allowing for the curing of any disease, repairing any genetic disorder. -- so you want to cure aging then- how many billions of people you think can a planet with a 6k km radius sustain ? You think Claus Schwabs of the world wont buy it out to keep it to themselves ? >> 2) Commercially viable fusion energy. Will change a lot…

> -- That will eventually happen, and electricity will be just as "expensive" as it is now, simply because the price of a product has nothing to do with its cost and everything to do with the purchasing power of its intended audience.

100%

If we had fusion tomorrow it would help decarbonise our grids, which is a great thing, but the consumer would see zero financial benefit. Companies would charge the same and make record profits.

This is literally happening right now! The market price of energy in Europe has dropped after a huge hike when Russia invaded Ukraine, but customer bills are still extortionately high

ok full disclosure, I had not heard the term Black Swan event before and I was trying to remember what happened in the movie

Things also tend to be invented at about the same time at different places. I wonder if there are other people who were this close to invent it but just couldn't get it right.

Apparently the theory behind LK-99 was inspired by the studies from Eastern European scientists. However, after the Soviet collapse, the study was lost.

very interesting, is there a an article about it?

One somewhat ironic fact of this story is that the rogue former employee perhaps deserves some credit for bringing this thing out into the world. They had been working on this for quite a long time themselves, rightfully so. But now the whole world is working on it and exploring other methods and combinations of materials I would assume (to improve upon the original design and avoid any patents). How long would they…

We will never know, but maybe they receive some governmental pressure to never publish and pretend the research lead nowhere so that their country only gets the benefit.

But the rogue scientist wanted to share it with the entire world.

It would make for a nice movie.

We’ve survived for a few millennia so I think your sentiment is valid - it’s more likely that “good black swan” events happens more often that “disastrous black swan” events.
