<p>2.2 Animals and Study Design
The study comprised two cohorts of C57BL/6 mice: young adult (3 months old) and late middle-aged (18 months old). We chose 18 months old mice, as this mouse age is approximately equivalent to a 60-year-old human (Dutta and Sengupta 2016).<p>I posted paper above, DOI was linked at the end.</p>

<p>I had to laugh as I read this, but it feels so appropriate to the current state.<p>I will say off topic that, speaking to an early googler, there is actually documentation of meetings where they discussed what "don't be evil" meant and decided actual business options they should and should not pursue. It was not <i>just</i> a motto or a "code of conduct", but meant as and used to justify consequential actions.</p>

<p>If you're not aware 3M (and other companies) now sell electrically de-bondable tape.

<p>Well, there's all sort of different problems, but most modern display technologies both in software visual profile and hardware implementation use LUTs. When sRGB was born the monitors were unable to even meet it as a spec so some crazy simplifications were fine. Now we're using those bits to drive HDR monitors over much larger color volumes and dynamic range, but it's hard to move on from the "good enough" legacy of sRGB.<p>Certainly, eyes don't have a consistent gamma, they don't even match between people, much less outside the foveal field.</p>

<p>If you're using sRGB with 16bit color you already have problems.
It is an 8bit per color hack that worked perfectly well with CRTs and early LCDs.
There were multiple different hacky versions with different vendors that were visually indistinguishable on displays of the day.<p>Even most modern displays are not really capable of more than 10bit color (RGB miniLED and QD-OLED barely are). Even REC2020 doesn't need 16bit.<p>sRGB doesn't even have a consistent gamma, and it's not anywhere close to uniformly covering the color volume. Why use it? DCI-P3 works fine.</p>

<p>Normally, discussions of climate refer to the last 12k year interglacial period as having come out of an "ice age". You're using the broader geologic term referring to any presence of any polar ice cap as an "ice age", which would cover the last 3 Million years. So what you're saying is that in the 300k years homo sapiens have never existed outside of an "ice age" and that the our speciation (eg in savannahs of Africa) was driven by the many glaciations of this current Ice Age? Even homo habilis hasn't been around that long.<p>That's saying that since the continents and earth's currents haven't changed, we're in the same age, AMOC is a minor technicality, and the oceans would need to rise to the straight of Panama to be significant.</p>

<p>In Japan the cost of building the tunnels through mountains and undersea for Shinkansen ranges from $20-100M/km. Since there's no default ownership of subsurface land rights in CA it would be cheaper and faster to dig tunnels than pay for the land rights and environmental impacts.<p>For the $231B you ought to be able to get 2-3000 miles of tunnel done (3x what is proposed on the surface). Of course the stations are still a huge cost, because those have to be above ground, but you could choose where to put them. The bridges and aqueducts that have been built so far (Bakersfield to Merced) are intentionally where land costs are low and no one will ride them.<p>I agree, this isn't about figuring out how to build high-speed rail for riders. This is about figuring out how to extract maximum funds from tax/rate payers. It's just like PG&E. I'd go as far as to say that all the consultants and construction companies that have been paid should be banned from future public infrastructure builds unless the money spent is paid back.<p>And I WANT highspeed rail.</p>

<p>It's fairly hilarious in a dangerous way, how confident people are that neither they, nor their boomer parents could be fooled by a persistent LLM with access to their mail, text, voice, and that of their co-workers and supervisors. The social engineering attacks have always been a weak point, and now they can be combined with other information to target individuals and fake voice/sms tone.<p>Look at what happened on r/changemyview. That was over a year ago, using only text, and not only went undetected, but was highly effective at changing opinions.<p><a href="https://www.reddit.com/r/changemyview/comments/1k8b2hj/meta_unauthorized_experiment_on_cmv_involving/" rel="nofollow">https://www.reddit.com/r/changemyview/comments/1k8b2hj/meta_...</a></p>

<p>They compounded them, which just means buying the API, reconstituting it, adding another compound (Vit B6), and putting it in sterile vials.<p>They did not make the peptides. They sourced them from China.</p>

<p>It would be shocking to me if the large model trainers didn't have tools like this to analyze their outputs, but this is <i>interesting work</i>!<p>You can see who likely (post)trained/distilled their models or borrowed parameters from each other. I do wonder if the 32 dimensions were chosen/named from principal components or pre-selected and designed, but the tool seems like an effective discriminator in any case.<p>Were the prompts similarly selected for orthogonality? I've wondered how the different LLMs would respond from iterative zero-shot prompt_n generation by summary from a previous response_n to generate zero-shot response_n+1. Would it statistically converge to a more distinguishable prompt for that LLM?</p>

<p>Actually, you just described most of the tele-health and compounding pharmacies that carry GLP1s!<p>Where do you think Hims, Ro, Brello, or the rest get the APIs they sell to their customers? They get them from grey market suppliers in China. They don't go to Ely Lilly or NovoNordisk and say, "politely sir, may I skirt around your IP and sell your drugs for 10x what they cost instead of 10,000x what they cost?" Hopefully, they test them and filter them and use sterile/pharma processes for what they sell to their customers. Well, except for the Medspas, those are just wild west snake oil farms.</p>
