Ice is less dense then water due to extensive hydrogen bonding, lattice of hydrogen bonds form when water freezes. Chemistry!

Wait what the hell Trump actually went ahead and captured Maduro today? Holy shit I did not keep up with the news.

I did indeed read those papers. Some of them were decently interesting actually, but none of them say “ADHD is caused by food dyes”, one review paper explicitly states the cause is unknown.

They suggest that food colourings MAY (not do, may) affect behaviour and exacerbate the symptoms of ADHD, and that more research is needed.

To note, the meta-analyses all say that more research investigation is needed for a more concrete conclusion. Additionally, they add that the studies may have had publication biases or had small ungeneralisable sample sizes. (their words, not mine)

The third meta analysis says “Improvement in the identification of responders is required before strong clinical recommendations can be made.”

https://pmc.ncbi.nlm.nih.gov/articles/PMC3441937/ (first trial you linked) states that AFCs are not the main cause of ADHD, but it may exacerbate the symptoms of it. Also, they note that it may not be limited to ADHD (general effect was replicated, they said). Current status of evidence is inconclusive.

https://pmc.ncbi.nlm.nih.gov/articles/PMC9052604/ (first recent review you linked) states that the studies that show positive results (5 of 6 since 1990, 8 of 19 before) that may affect behaviour of children (but does not explicitly state that it causes ADHD) and that more research is needed for a conclusion.

https://pmc.ncbi.nlm.nih.gov/articles/PMC9573786/ (last one you linked) states that the cause of ADHD “is not known, but, along with genetic factors, it is possible that environmental factors including toxins and diet may affect symptom severity.” (again, exacerbating the symptoms!) They also note that more research is necessary. “There is a need for more research to determine how these individual compounds affect humans” “More research is necessary to describe the neurotoxicity of artificial blue dyes in humans.”

But certainly not ADHD…

Artificial colours don’t cause ADHD I think. And just before you ask, no, vaccines don’t either.

I remember there was this one case where a particular red dye caused a form of cancer and is now out of production, which is interesting. And also Napoleon’s (I think it was him?) walls had a toxic green paint that certainly didn’t help his chances of not-dying

Fair enough

One more thing, for PSUs, is the Seasonic Vertex GX1000 better than the Focus GX1000 in any way aside from 2 years extra warranty (10 vs 12 year warranty)

Both the U.S. and the Soviets supported countless proxy wars across Asia, the Middle East, Africa, Latin America, and the Carribean, with weapons, training, manpower, and a lot of propaganda. So many small conflicts were blown up to huge ones by massive amounts of funding and support from the two nuclear superpowers. They both had numerous spy operations involving the CIA and KGB respectively. Both sides were aggressive, there was no side that was not.

both can be true

It’s a nice idea in theory, but that requires all the humans to be super altruistic and just give stuff to everyone for seemingly no benefit to themselves.

As the other person said, bartering would only work if you both have the thing you need. If Allen is a woodworker and doesn’t have any bacon, and Alice wants some bacon in exchange for X thing, then a transaction can’t happen. It worked well when different tribes of humans could sustain themselves (hunt their own food, gather their own resources, etc.) and when people had very few needs (no technologies, no nice furniture, less mass produced plastic, etc.)

In other words, humans are selfish, and the promise of future benefit in the metals and paper (and now 0s and 1s with stuff like PayPal and plastic cards) we call “money” is necessary for people to trade effectively in the modern, interconnected world.

There’s this neat laptop by Honor (the “MagicBook Art 14” I believe, I think it has the option of either a Snapdragon X Elite or the Intel Core Ultra series processors…) where the webcam magnetically attaches and can be flilled both ways, and tucks in to the side when it is not needed, so the display doesn’t have a notch/hole.

It’s a gimmicky feature though, most people don’t need something like that, and the people that do have other ways to go about it (e.g. document scanner, smartphone, mirrorless/DSLR camera). Most laptop webcams aren’t very good anyways

For PCs, I guess you could mount a webcam the other way? For most people you would only see wall.

Oop, yeo, they do. But it’s optional I think since I never used it

RSS feeds are incredibly useful, I use them to keep up with all sorts of news. Most feed readers also let you group different feeds into categories. I have mine divided between science, technology, world news, etc.

Many RSS feed readers let you create an account to sync your read items and such (useful if you have multiple devices, also useful for bad actors to see everything you’ve read…) but there are plenty of readers where it’s not a thing/is optional. On Android, there’s “Feeder” and “CapyReader” (I use the latter) and on iOS there’s NetNewsWire

Nope

I don’t think anyone needs more toenail pictures

When I was little, I think I kicked something really hard and bent my left little toe (pinky toe? Why do people call the little finger a pinky anyways? It’s equally pink as the rest of the fingers…) where the toenail now grows way off to the right, it’s bent to the right permanently it seems, which is kind of interesting.

He’s asking why, after you cut your toenails, it gets pointy in the middle. It’s a fair question, I just think nobody likes to see a picture of toenails in their feed, it would have been better if that was omitted

I think I understand what you’re saying. You are wondering why the middle of the toenail (not body, feet are clearly on the very end of that) grows a bit faster than the bits on the side, leading to a toenail that’s a bit pointy in the middle, which could be quite annoying to you.

I think it’s because, when you cut your toenails, you almost always cut from the corners, not straight on, leading to a toenail that is more pronounced in the centre, since you usually make the edges of the toenail shorter than the middle.

Another theory is that (pulling this from a hat, I didn’t take Biology), since toenails are essentially just dead stuff that’s growing from the corpses of alive stuff underneath the toenail, there was some evolutionary advantage to having extra alive stuff in the middle of your toenail. (perhaps to better protect that alive stuff, as it could be more vulnerable out near the edges or maybe to make the toenails sharper and pointier for better grip)

There is more alive stuff in the middle, I know this from experience that when cutting too far into the toenail, it’s far easier to touch the alive bits in the middle (it’s painful!) compared to the edges.
