The recent discovery of room-temperature superconductivity was cool but required impractical pressures.

What is the future of superconductivity?

Apparently superconductivity arises from a desirable interaction of electrons and phonons... Would it be possible to nanostructure or influence a material so that phonons and electrons interact in such a way that superconductivity is achieved?

Did the high pressure cause this strong coupling? Why can't it be engineered somehow to be even stronger?

>> No.12401993

>>12401925
Because the high pressure compresses the lattice making the coupling stronger. iirc theorists actually worked it out in computer simulations first before experimentalists then proved it. This is no known method to distort the lattice in such a way without extreme pressures.

N,N-dimethyltryptamine compound found in the hallucinogenic tea ayahuasca, regulates adult neurogenesis in vitro and in vivo

Abstract

N,N-dimethyltryptamine (DMT) is a component of the ayahuasca brew traditionally used for ritual and therapeutic purposes across several South American countries. Here, we have examined, in vitro and vivo, the potential neurogenic effect of DMT. Our results demonstrate that DMT administration activates the main adult neurogenic niche, the subgranular zone of the dentate gyrus of the hippocampus, promoting newly generated neurons in the granular zone. Moreover, these mice performed better, compared to control non-treated animals, in memory tests, which suggest a functional relevance for the DMT-induced new production of neurons in the hippocampus. Interestingly, the neurogenic effect of DMT appears to involve signaling via sigma-1 receptor (S1R) activation since S1R antagonist blocked the neurogenic effect. Taken together, our results demonstrate that DMT treatment activates the subgranular neurogenic niche regulating the proliferation of neural stem cells, the migration of neuroblasts, and promoting the generation of new neurons in the hippocampus, therefore enhancing adult neurogenesis and improving spatial learning and memory tasks.

I had a look at this study and it's surprisingly of better quality than a lot of other papers on the same topic often posted here.

That said, there are a few things to keep in mind when drawing firm conclusions. Most importantly, I don't find the demonstration of behavioral relevance particularly convincing. The effect size of the between group differences in escape latency are quite small, and the authors seem to treat trend level effects as significant. Critically, co-administration of an antagonist does not block the behavioral effect, at least not when taking escape latency as the measure of interest. So this means that either the behavioral outcome measure is flawed, or the molecular pathway that underlies the behavioral effect is different from the pathway that is linked to neurogenesis.

I know it's tempting to conclude here that if neurogenesis is ramped up by DMT, it results in beter memory performance. But the subtleties in the data here indicate that any changes in memory performance may not be the direct consequence of the pharmacological effects of DMT.

You speak fair words about science, but! I see behind your toleration of science! In a comer of your heart you believe, all this notwithstanding, that you do not need it, that you are being magnanimous in according it recognition, in being indeed its advocate, especially since science does not exhibit the same magnanimity in regard to your views on life. Do you realise that you have no right whatever to this exercise of toleration? that this gracious demeanour is a cruder insult to science than the open mockery of it which some arrogant priest or artist permits himself?. You lack the strict conscience for what is true and actual, it does not torment you to find science in conflict with your feelings, you do not know a greedy longing for knowledge as a law ruling over you, you do not feel it as a duty to desire to be present as a witness wherever knowledge is present and to let nothing already known escape again. You do not know that which you treat so tolerantly! And it is only because you do not know it that you are able to adopt so gracious a demeanour! You, precisely you would glare in bitter and.fanatical hostility if science should ever look you straight in the face with its eyes! What do we care, then, if you practise toleration towards a phantom! and not even towards us! And what do we matter!

With the "no free will" option you are probably referring single universe, unaltered timeline type of time travel. But it's better to not bring free will into it, since either it's libertarian free will which is simply self-contradictory and makes no sense with or without time travel, or compatibilist free will which is totally compatible with this kind of time travel.

Traveling to the past will inherently spawn a new timeline so you can never return to the original future, only the alternative one you've created

If Democrats had commited no fraud (or didn't know about it on a local level but were confident that no fraud was commited), there would be absolutely no reason to wipe these computers. In fact, their integrity should be a top Democrat priority as it solidyfies their victory claims and tampering with them for the sake of an "update" would be absurdly reckless. If they truly are wiping the voting machine computers this means three things:

>1) They have committed fraud and are aware of it.

>2) As Democrats destroy the evidence, Trump's prospects for victory diminish rapidly.

>3) Since the judiciary and other "checks-and-balances" entities have not intervened to prevent Democrats from destroying evidence, they have already accepted the Biden victory - therefore Trump lacks the support required to oppose Biden.


Trump will lose and in 20-30 years historians will point out the the Fraud with cool matter-of-fact rhetoric based on the abundant discrepancies and red flags, similarly to how the CIAs endeavours to overthrow governments in SA (for instance) used to be a crazy conspiracy theory and is now accepted fact, even though the available evidence then and now is virtually identical.
It will only be "obvious" decades after the fact, even though we know it's true even as it unfolds. There's too much inertia in the political system to reckoncile such events, the same happened after 9/11 and during the Iraq "WMD" war campaign.

Yes. Because Quantum Immortality is really telling, the people who want it to be true want to kill themselves. They cannot handle this world and they hope and they dream that there is a life after death, that is like ours but where they didn't end up in the same place. But the causal chain ensures that they'll end up at the same place. So one death is all deaths for them and they simply enter the void, incapable of thinking.

while I do see the normal 1=0.999... and quantum immortality threads EVERY FUCKING DAY.... I still find people who can talk about gauge theory and higher up physics maths so, pretty worth it

How does someone calculate the odds in this story? (see pic) Which relevant factors should be considered?

This is a cluster where each case shares a relationship with the other.

Just admit it, you failed statistics.

I'm pointing out the flaw in your logic, retard. and statistics is a part of my phd. you're just chasing some nonsense and throwing out any information that would imply you're doing anything other than that

Here is a simple question: Same geographical area, decades apart,... positions of planets should appear random under normal circumances but they don't. Why is that?

what the fuck does this mean? planets have orbits. their motion is predictable and results in repeating patterns.

Venus is closest planet to Earth about 35% of the time.

If you pick three random moments in time, the probability that the closest planet is Venus at all three moments is 4%.

>This is a cluster where each case shares a relationship with the other.
The relationship is that they disappeared at the same approximate area at different times. So every place that has three recorded disappearance events, which is a lot of places, is another attempt at that 4% probability. If we assume there are only 20 places in the entire world which fit this description, you should expect a 56% chance that you'll find a cluster like this somewhere.

In short, it's not anomalous, it's literally nothing, take your meds.

stuff like this is really going to set back public trust and support of the soiences, not that it will make any difference.
