It is annoying that they use different scales, though. The overall studies are not strongly conclusive regarding the effect of the buyback program, it seems.

I also believe that in Canada there are stricter rules for storing and securing firearms and generally do not allow carrying guns outside of occupational reasons. This counters the mindset of using guns for split-second self-defense.

Yes, they can. The issues is that many studies rely on accurate statistics collected by agencies such as CDC to document gun deaths, for example. Without those you 'll have to try to estimate these numbers from other public sources (say, police reports) which can be difficult and less accurate.

I mentioned that earlier, there are restrictions on research in place, including preventing CDC to collect relevant information. And the lack of these data is hampering research aside from the lack of actual funding.

I have mentioned earlier that gun-related deaths and injury are an underreseached subject. The RAND corporaton (and independent think tank) has made a similar point. However, they also have collected a summary of existing studies to synthesize at least some of the findings, incomplete as they may be (link here). The strongest evidence seem to indicate that child-access prevention laws might decrease suicide as well as unintentional injuries and deaths. Background check may have a moderate impact in decreasing suicide and violent crime. Likewise, there is moderate evidence that stand-your-ground laws may increase violent crime. For other outcomes the evidence was inconclusive.

I think only part of it does. But at the same time they overlook that the idea of having militias is also connected to the fact that many of the founding fathers were suspicious of a standing army. Madison famously said : I am no constitutional scholar, but I kind of doubt that the 2nd amendment was created with also having the largest military power in mind. Rather, militias could have risen in response and/or to prevent the creation of a large military force that could be used to suppress the populace. But that ship has clearly sailed (or taken out by a laser guided missile).

So if I understand it correctly the issue is that known extraction methods would also release bound isocyanates?

Isocyanates are associated with asthma in sensitive persons. IIRC this: was generally assumed to be true, but recently more sensitive methods were used and isocyanates were detected in a wide range of cured products. However, and quite commonly in these studies, it is not quite clear whether the detectable amounts pose health hazards. As MigL mentioned, once symptoms show up (which can be skin sensitization or asthma-like symptoms) it is better to replace them. Likewise, hypersensitive individuals may be better off not having those products around.

IIRC dogs have dichromatic perception, which allows them to see more than black and white (but fewer colours than we do).

There have been many threads in which gender differences in the brain have been discussed. The real question is how big are these differences and do they justify societal differences. Most research is not conclusive in that regard. Most of the societal aspects you mention later in your post (but did not outline earlier) seem to be the result of gender roles characteristic of a patriarchic gender roles (you have only focused on a few aspects, though there are others with different ramifications). However, your anecdotes at your school specifically may be about something else entirely. As a whole I do find the posts somewhat incoherent, though.

I hoped for genuine curiosity. But judging from the outline I should have known better. The quote is from one of the early feminists, Caroline Bird. But obviously one cannot argue with a random youtube video (like, literally).

Yes and context matter if one wants to ask how to deal with it. That is not what subspecies are. How do you define sexism? Note that there is a difference between sexism and misogyny or misandry. As such, sexism exists on a spectrum. A good quote that I heard is "Sexism is judging people by their sex when sex doesn't matter".

Take a look at the atomic force microscope, which is a further development of that principle. One of my favorite toys.

Actually I would be careful with generalizations in that regard. There are studies that indicate that sexual selection often favours dissmilarities in major histocompatibility complex genes. I.e. people prefer people who are genetically dissimilar (and hence likely to look different). The reason being that a larger variety in these genes offers selective advantages to combat pathogens. A difficulty here is the large numbers of covariates and the complexity of outcomes (such as stability of relationships). For example, having a similar background can lead to more stable relationships as one shares a similar language and beliefs.Also, people with same background may also be more genetically similar. If one only considers genetics, one may assume that the basic is genetic, whereas it just coincides with the actual determining factor.

Going through lit two things stood out. It is still commonly used and much of the utility is, as John said, for debridement. What has been criticized is that its antibacterial efficacy is undertested. Nonetheless there are publications that ~2% or even lower concentrations seem to have benefits in a variety of applications, including for grafts but also for general wound healing. There are a few that indicate slower wound healing at higher concentrations and in animal studies even concentrations as low as ~200 mM were associated with delayed healing. But at lower than 10 mM would healing improved. By skimming, I could not find any publications with decent data that would support the notion that it could be unsafe (if that was the assertion in the video, I have not watched it).

The second article seems to be more interesting. Will peruse it when time permits.

I find it a bit heavy on inductive reasoning and a bit light on contextualization (it is just not a very scholarly article). I have read that some trends of women's clothing were essentially co-opting male trends as part of the feminist movement. But I am not sure what historians have to say on the conclusions by the author of the above article. Here (still not a scholarly article but with more sources) it is implied that the loss of pockets was driven by a change in waistline.

In that case, let's talk about the bobbit worm (Eunice aphroditois). It grows up to 3m (I believe around 10 ft in silly units), It can get into aquariums by hiding in rocks. It also seems to produce a nice toxin, though I think it has not been properly characterized. https://vimeo.com/28280553

Actually there are many, many companies who do that. Primers (short fragments of about 20 bps) have been around forever (now at the cost of few bucks) with all kinds of modifications that you might need. Longer fragments (up to ca. 3000 bp without additional cost for stitching) are also available, but I think the cost is closer to 0.2 cents per base, meaning that an average gene may cost more than ~100 bucks a piece.

Yes, cor syrup would show up there, after all it is the US' favorite (subsidized) sweetener. It is true that it is literally everywhere, and coming from a elsewhere it is hard not to notice. Even things like sausages are often disgustingly sweet. Sometimes it is even worse if you buy a product that you think should be the same as in Europe (as in the Ketchup example) but even things that are supposed to be sweet (e.g. chocolate) are made sweeter and creamier in the US. That being said, it seems that the sugar content is slowly increasing in Europe, too, from what I heard. The highest levels were ~125g/day, whereas Germany is around 100 and UK about 93 g. In comparison China has about 28g daily intake and India only 10g.

I will have to dig out some books to be sure, but now that I reflect on it, I am likely (and embarrassingly) conflating events surrounding the spurt of Latin translations in the 12th century. Especially Aristotle's work were translated, circulated and maintained in the Middle East (but also Egypt and Constantinople), together with Greek manuscripts as early as the 8th century (via the Abbasid caliphate). To this point only few books were translated into Latin (of that I am fairly certain). At the same time few Greek works existed in Western Europe. However, as you rightfully pointed out, that does not mean that the books survived exclusively as Arabic translations. It would probably be somewhat more accurate to state that the works survived to a large extent due to contributions of Islamic scholars at a time when the ideas fell out of favor in the West. So yep, after writing this I am now quite sure that I was wrong. Which again demonstrates the importance of coffee as a part of as breakfast. Good call, btw. We cannot have something factually wrong be on the internet now, can we?

In that context it is perhaps interesting that much of the writings of Aristotle that we have now is based on translations made between the 12th-13th century. Most of it based on translations of Arabic texts, which effectively saved his writings (and quotes) from vanishing from history.

Yeah, the same way I fine tune my car with a sledgehammer. It runs faster out of fear.

The question is too broad to have any meaningful discussion. The population of chronic cannabis users is broad, and as such they differ in many relevant aspects. Some may be embedded in large social groups, some may be loners. Some may be affluent, some struggling. Some are old some are young. As such each of them would be subject to different kinds of social pressure. There are, however, a lot of studies that show a correlation (though not necessarily a causation) between chronic use and e.g. mild cognitive impairment and poor mental health. There is specifically a strong association between high level chronic use especially among teens and development of schizophrenia and psychosis. However, it is not clear whether it is caused by cannabis use or that people susceptible to psychosis are drawn to cannabis use. Some studies focus on the mechanistic link (e.g. Malone et al Br J Pharmacol 2010) but others look into the societal area. So the first question cannot be answered and the follow-up is just a non sequitur.

Possible and rather typical for what effectively is fusion food (but less pretentious). Incidentally, food is for me one of the best arguments for immigration.
