Iris Alexandra's twitter is especially enthralling. Seems like so much discoveries and innovation happens from computer science to physics, chemistry and biology all from people with anime profile pictures.

There's a certain subset of people on the intersection of high IQ, high-functioning ASD and LGBT that produces a lot of high impact activity in STEM fields.

High-functioning LGBT for sure

It is interesting to see how much of the replication is done by the Chinese and how little is done by the Western countries. Is this the difference between the making-stuff-happen attitude and the sclerotic attitude?

Someone on Twitter spoke on this, so I cant' confirm its accuracy. They said that the reagents for this are usually made in China. As soon as this paper was published, labs in China bought out the reserves and they became hard to source in the West.

Saw some people hyping up markets where people are betting on prediction markets whether or not LK-99 will replicate. Can't help but feel like that money would be better spent just paying off some labs to actually try to replicate the process. The response I got from a predictions market enthusiast was that having a sufficiently large market would motivate people to attempt to have the process replicated and buy opti…

This type of instictive negative reaction to prediction markets is, unfortunately, common, but, I think, misguided.

Prediction markets are one of the (or just, the?) best ways of aggregating knowledge from multiple sources and producing the best predictions. Having good legible predictions of impactful events such as LK-99 replication is extremely useful for society - it would be an invaluable input for a savvy policy maker for instance.

What I think is silly is that vastly bigger amounts of money are put in betting markets for any mildly important sportsball game. Meanwhile, markets on LK99 replication, one of the most potentially important possibilities in the world right now have only on the order of hundreds of thousands of dollars in them.

And there is no scamming involved. If you are participating in a prediction market, either you have some reason you believe you know something the market does not or you should expect you are simply subsidizing those with better information. The latter is a perfectly reasonable thing to do - it's not easy for an average person to "pay off some lab", but if they provide liquidity to the prediction market they are giving an explicit subsidy for anyone that can answer the question.

Assuming LK99 is legitimate, my hope is that the principles that make it work are more broadly applicable - and with that, refined production processes or newer alloys can be found. Simply knowing that it's possible would lead to a huge amount of research immediately focusing on this kind of thing. There's nothing more revolutionary than a discovery of a new class of materials. After all, we often name eras throughou…

Is there any HN effect by which enough contrary early opinion here could increase the odds of eventual triumph? On the chance that there is, I will do my part: In mice.

No synthesis. Less critical current than YBCO. Lame.

Currently, Cold Fusion used in small scale isotope breeders for medical purposes. One 2kWt breeder with CF can replace 100kWt traditional breeding plant.

Cite please. I think you've mistaken neutron feed sourced medical imaging radionuclide from low energy research reactions for cold fusion e.g. https://www.itnonline.com/content/fda-approves-additional-mo... NorthStar produces non-uranium based Mo-99 in collaboration with its manufacturing partner, the University of Missouri Research Reactor (MURR), in Columbia, Mo., using neutron capture technology.

I think there's also an aspect of doing it and presenting it in an unusually attention-grabbing way.

Stone Age Bronze Age Iron Age LK-99 Age (source: https://news.ycombinator.com/item?id=36869209 )

Stone Age Bronze Age Iron Age I would add Steel Age here LK-99 Age

Given that human flight and putting things in space rely on Aluminium, I think that's worth a mention too.

Are there any prediction markets where you can bet money on this? I thought people talked only about Moneyfold, which is just a game. (You cannot take money out of it, although you can use it to make a charity donation.) I suspect that people on actual real money market would make different predictions to Manifold.

I like that that website seems to use just smallish penny amounts, no big betting amounts. And that it's a simple formula; if you're right, you win $1 per share, if you lose, you get nothing. There's one about whether Trump wins the election with everyone voting 'no', so the winners will gain fractions of pennies on their bet. But if he does win, those voting 'yes' can gain 99% of their bet.
