As in, if certain species decreases, but another increase, it's not clear to me one is more bad than another.
Obviously, wouldn't want entire ecosystems wiped out. I'm just curious what a good measurement of ecosystem health would be.
I'm sure there's one out there hopefully, as technology advances, we'll be able to mitigate the effects we have on the environment, and occasionally, maybe even help it.
It made me realize why structures in biology might arise in very short time spans "fully formed" as opposed to the the relatively slow process of natural selection (which is an important part of the evolutionary process, but strikes me as insufficient given the short time scales at play).
It makes sense if simple rules can create complex structures. Then it would just be a matter of "exploring" this universe of complex structures which would likely produce this wild assortment of distinct organisms, gradually shaped and refined over time.
I don't think it's the full picture, but it adds an interesting perspective I never considered before.
About 5 normal Vitamin D pills every few days so.
I was trying to treat something else out of desperation and noticed my tooth sensitivity more or less vanished.
Which makes sense when considering their role.
But as always, n=1.
Don't understand the script, but this is only for personal use. I wouldn't do the same in a work setting (obviously).
And in this specific example, it's been quite a powerful tool to make many parts of my life easier.
Interesting. And somewhat counterintuitive.
CZ and SH were employed by Tsingtao Brewery Co. Ltd. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.”
From the study:
What I find interesting how the thymus becomes essentially a blog of fat as we get older and partially explains why infections tend to hit us harder as we age.
Tweets in question:
"This chart doesn't measure app usage, only traffic to the website on desktop and mobile." https://twitter.com/Similarweb/status/1676576445764624385?s=...
"The graph indeed shows traffic only to the specific URL, http://chat.openai.com. It should be reviewed in this context." https://twitter.com/Similarweb/status/1676573510490046467?s=...
If you notice the app came out in May 2023 and traffic decreases for the first time in the following month in June 2023.
Additionally, you may notice the tweets refer to a specific chart, which might give the impression if you go on the site, they have the actual data, but this is not so.
As of July 7, 2023, Similar Web can't measure iOS app usage. Only their relative ranking on the App Store which doesn't tell you much about daily traffic usage, although we might be able to infer some patterns.
"Usage data is currently available only for apps in Google Play Store. We're working hard to support iOS apps soon"
https://www.similarweb.com/app/app-store/6448311069/statisti...
Additionally, the article has this to say, which might also give a false impression:
> Downloads of the bot’s iPhone app, which launched in May, have also steadily fallen since peaking in early June, according to data from Sensor Tower.
Downloads isn't the same as traffic. Once you've downloaded an app, you don't generally delete it, then download it over and over again. You just use it and that isn't being measured. Although I would expect traffic usage to slow down or decrease somewhat as downloads decrease as well. I just think there are other factors playing a role here as well that aren't being documented.
Growth can't happen forever and it may be that it's slowed down considerably, but it's also possible the decrease is due to users switching the platform they use to access ChatGPT. As it stands, it's not clear from the data from what I've seen. It may be that users switched en masse to the iOS app or something else entirely.
Would need more data to clarify and confirm.
Also, what the heck is up with this tagline for their newsletter? It sounds so adversarial.
"Tech is not your friend. We are. Sign up for The Tech Friend newsletter."

Just being able to take blood tests in general to get a better sense of what might be going on can be so informative.
Yes the article strongly implies this with some added nuance:
> I’m extremely grateful to Cookie Clicker for the journey it put me on, but even if I hadn’t ended up learning JavaScript because of it, I still wouldn’t regret, and would cherish, the many many hours I spent tinkering and clicking away in my college dorm bedroom.
For example, you'd be surprised at the number of people who have met on Twitter. It's quite a lot.
Even John Carmack recently met his significant other on there following his divorce.

But I haven't heard of any place like that so far. No real competitor for users to jump ship towards.
As it stands, there doesn't seem to be anywhere for these people to go, so they'll likely come back after a few days. Habits are hard to break.
Habits are a moat too.
Then you can run searches for content even if the exact words aren't the same.
Like let's say you have a document titled "Measuring canine tooth caries over 2004-2020" and it never once mentions the word "dog".
If you type in "dog" after doing the embeddings, it'll suggest that specific document because "canine" and "dog" are closely related.
Great way to organize large groups of texts, there's plenty of YouTube videos on how to do it, and best of all, you don't have to spend time manually organizing everything. You just let the machine model do it for you.
You could even get it to auto-tag your documents based on what it thinks is the best category for the document and make it easier for you to parse that way as well.
I know GPT-4 in particular has made exploring new, small projects fairly easy.
You could do something similar. Mix up the tediousness of doing the same thing day after day. Or find ways to automate certain portions of your work, if possible. I always get a kick out of that.
Or talk to your boss and explain the problem. You could explore switching things up a bit. That's always an option as well.
It’s talked about in terms of Long COVID and whether or not it’s psychosomatic, the policies made during the lockdowns, and so forth, but always with so much emotion, and sometimes for good reason. I don’t want to dismiss that or trivialize it. Those are important topics to discuss for how we’ll handle future pandemics.
But the evidence is accumulating that COVID does seem to impact CD8+ T cells, causing T cell exhaustion and reduced effector response. One running hypothesis is that the impaired immune response is caused by a persistent viral reservoir infection, particularly in the gut (although not all people show signs of a spike protein months after the initial infection) causing your CD8+ T cells to express more inhibitory receptors (similar to what happens in HIV or cancer with excessive and prolonged exposure to cancer cells).
Another hypothesis that is lesser known but I find particularly compelling is gut dysbiosis following a COVID infection causing a persistent immune activation that leads to T cell exhaustion or impaired T cell functionality especially through persistent activation of the dendritic cells (which are important for presenting antigens to the adaptive immune systems (i.e. T cells, B cells, etc)).
I think a researcher put it best when they said COVID is roughly halfway between HIV and the common cold in terms of the impact it has on the immune system. It may also not be accurate. We have to find out.
For context, think about how long it took to realize the Epstein Barr virus was a causal factor in multiple sclerosis. It took years of evidence collecting and data analysis to eliminate other confounding variables.
We shouldn’t rush to judgement or a narrative, but remain calm and dispassionate here and examine what’s going on, both for the virus, the vaccine, and the actions taken during the pandemic. It’s important we get it right.
It's a bit like being given a piece of paper to solve math problems, instead of trying to do it all in your head.
Makes a huge difference.
Like being able to do rule-based sentiment detection analysis and injecting that code into my browser, so I only see neutral/positive comments on Hacker News instead of the usual cynical takes lol.
Metabolic processes and immune pathways are closely interlinked together (such as through the mTOR pathway).
Activate mTOR and you get the signal for T cells to proliferate as well as muscle growth, especially in the context of hypertrophy.
Not the kind that looks like sludge, but the kind that would be indistinguishable from a beef patty you buy at the store, not least because it would be a more efficient way of producing food at scale.
But also because some of that technology would also eventually be applied to the creation of human organs.
And I'd like to live in a world where the waiting list for an organ transplant is just a few hours for everybody.
