1. Less than historically still has a quite high baseline compared to after ULEZ - if it was more polluted, presumably the change seen here would be more dramatic. 2. Definitely kickstarted it, but we're looking at taking that impact

I've seen this concept of using LLM/AI/etc for high throughput discovery of materials so, so often in the past 5 or so years and yet there hasn't really been any impact as a result. I think this is the first one that has

These things are interesting but for the most part quite dull and very industry-facing. Just mash together a bunch of random elements and see if it improves the thing you want to optimize.

The kids at private schools are specifically primed for every part of the application process, including the interview and interview questions in a way that state schools simply cannot. It does not matter how smart you are if your competiti

Honestly, when it comes to hacking things together with matplotlib I outsource all of my thinking to chatgpt to do the 80% of doc hunting that is honestly not worth it since everything in matplotlib is labelled inconsistently.

More to the point, when you write an article like this foretelling the doom of the american economy, why would you think you are able to brain drain any country? What stops the countries you are trying to drain from offering better incentiv

This is not really as simple as just going through the permutations. What this is in practice is a triumph of instrumentation. Before this, no one has imaged altermagnetic domain structure. The behaviour of these materials is intrinsically

To add a bit more to this, it's really a new class of magnetism. Traditionally we might think of ordered magnetic materials as being one of two: ferromagnets, which is what you think of when you think of magnets, and antiferromagnets.

Ultimately they still live in the country. They have ties to it. Their assets and wealth may be tied up in the country which is difficult to extricate. And, most importantly, their friends, family and life are in that country. It is absurd

I admit to not really being familiar with either, but it seems that this allows you to display comments alongside the paper in the browser, which is a very nice feature (and overall has a nicer coat of paint). At first blush, I find it a bi

Transparency I assume. I understand the admin likes free speech and maintains some transparency, to explain why content has been removed, and giving away your information is always a risk in legal issues.

The operator of the kiwifarms is himself a US citizen with a US business. It is an advertised fact that if a police force comes after or shuts him down with a legal reason, it will cease to exist and he himself has stated he wouldn't o

You absolutely can, and as you can see in this paper it is absolutely do-able to measure the resistance of these materials. They measure an insulator with something on the order of 10^6 ohm m. For reference, copper has a resistivity of ~ 10

There are measurement configurations that can be used to eliminate contact resistance (such as a van der Pauw measurement). Resistance, and electrical measurement in general, is the true proof - the Meissner effect is secondary and more con

Groups that typically do resistivity measurements on regularly measure low-temperature resistivities on conducting materials of ~ 10s of micro Ohm m. So if you're measuring in this range on a conducting material and hitting the noise f

Something that I find hard to understand is why there is superconductivity without cooper pairs; granted my understanding is related to more traditional superconductors and I'm not really very knowledgeable about the cutting edge high-

Can we stop promoting this ateapie loonie. Every post they made is so thick with narrative it is completely divorced from reality.

Not necessarily true. Complex compounds can be susceptible to oxidisation and generally decay and degrade over time.

Compared to recent controversial results claiming the exact same thing (actually, more restrictive than this claim), it's not insulting it is what you should expect. The recent situation with Dias this year[1] is now under investigatio

Glad to see a realistic take on HN. Endlessly frustrating to see people be like "this will be replicated in days". Yeah, sure, let every other lab just drop what they're doing, order all the reagents on express, do a thorough

As I mentioned in my above post, they have really dodgy data. Ideally, with something like this, you would have collaborators to verify alongside you as joint co-authors. I think something people underestimate if how easy to replicate sampl

0.3 T is pretty insignificant for everyday use - you need some pretty big coils carrying around 10 A to produce that sort of field. For something like this, the benefit would be in just making wires out of it for driving currents without lo

Agreed, this looks bogus. Some suspicious points: In the first paper, they claim to measure zero resistance (on a scale of microvolts), but are very careful not to show full RvT curves - in the second paper, we can still see significant cha

Consider you are another researcher (not the one who has just published). You may want to keep up to date with your field. This is good to do and it helps foster new ideas for now and for future proposals. There will be a selection of journ

As far as I am aware, they don't necessarily even do the final editing themselves; at least with the APS journals, they outsource the final typesetting to another company.

I think it is ridiculous to make such a sweeping statement about all of science when there is so much involved in each sub-field of science that brings its own problems to productivity and output. Take for instance the fact that nobody in E

No, the funding body specifies that all work has to be published as open-access. So if you publish without open access, you are getting yourself into trouble with the funding bodies which is a bad idea.

It's not even about the review. If it was, people who have Nature papers retracted would be in very dire straits (despite the fact, they tend to do very well anyway). It's a metric that you need to advance your career. A line on
