The muon g-2 measurements have nothing to do with floating rocks. This is not a superconductor update. This is a high energy physics thing about failing to find something beyond the standard model. Just your regularly scheduled "5 sigm

Can we foresee what the consequences would be if it doesn't stay within range? Is it 'just' a matter of adding some sufficiently elusive heavy particle to makes the numbers come out okay without really disturbing anything els

That very Wikipedia article says that adult neurogenesis essentially does not exist in humans, according to the latest studies. This used to be a very controversial topic, and some people still hold on to the older view, but new research ha

A glance at Wikipedia confirms that some pathogens are aware of PD-L1 and like to mess with proteins that regulate the immune system. Epstein-Barr Virus (EBV), the most common human virus, the herpes that 90% of people have had and a common

New neurons cannot be created in an adult brain (only new synapses), so over the years it's a very slow process of brain atrophy where neurons that die for any reason cannot be replaced. That already makes indefinitely untenable in a m

I truthfully don't know. A few people suggested they might have measured an insulator, the threshold where resistance changes being the breakdown where current starts flowing. I'm skeptical either way, I think it's too early

It shouldn't devalue the point. As you said, it's orthogonal.

It would be cool, but there are no world-changing implications to a new diamagnet made of lead. It's just kinda neat if you find one.

One response to the levitation video is that it is hard to distinguish from a non-superconductive diamagnetic effect, which can occur even in not very exotic materials. There are videos of graphite levitating that are circulating, for examp

There are several rumors from zhihu.com posts that various Chinese labs are racing to replicate it (which is not unexpected). Some claims that "The Institute of Physics of the Chinese Academy of Sciences has successfully synthesized th

Couldn't we make really thick wires to increase the current limit :) ? After all, there's no need for expensive cooling and the material looks reasonably cheap! (assuming it's real, of course..)

Thank you. I really appreciate your patience and your careful replies, as well.

>This is contradictory. Most drugs fail, how do we identify the efficacious ones other than through trials? One idea is to make trials somewhat less costly by relying more on post-approval monitoring, but there are more subtle critiques

That's fair, I'll admit I didn't check the inclusion criteria in the case of OP. I'll take your point, and I appreciate the time you took to write a good response, though I've read about enough examples other than t

You're right that there are alternatives, and there is an existing standard of care. I don't think I'm ignoring that. Let me clarify, I am not saying that patients with poor prognosis are being offered nothing. They are being

Trials are done in multiple phases, with a progressively wider population. There is a point where we consider a drug to still be unproven, but safe enough for human trials. I think that situations like TFA make a compelling case for selecti

It may help to not view the options as a binary choice between drugs approved under the current process and any drug not currently approved. What constitutes the acceptable tradeoff is the heart of the matter. On the one hand, even the curr

That's true, though I'll note that treatment options seem to have broadened a bit [0]. Thalidomide is effective, but suffers from cost and limited availability (in addition to the teratogenic effects). https://www.ncbi.

If we can only prove that an inconsistent system is inconsistent, and we can never prove our (presumably) consistent system is consistent, then it is incomplete. We can't say it's inconsistent just because we can't prove othe

The Busy Beaver numbers express a limitation of classes of axiomatic systems, not merely of Turing Machines. It's not merely that computers aren't guaranteed to be able to calculate these. BB(n) for some n <= 745 is independent

I could hardly disagree more, in light of all the goodness, the lives saved, the artifice that we have gained through hard work and choose to not throw away every day. The worries that we have today are, to me, preferable and much less viol

I haven't voted on that comment, but it's overconfident, it jumps to conclusions too quickly. It's possible aspartame is bad for migraines. Given that migraines are really bad, then you might as well avoid aspartame, it'
