You are not arguing from a valid scientific perspective, then. There are many unique brains in the animal world, including larger and more complex in certain areas. You start from the assumption that humans must be unique and then build your classification around that.
-
This is a prime example of making up definitions. Yours is that you think humans are unique and therefore are a different category. All other animals are less (less what?). The scientific definition is based on relationship and has a fairly stringent basis that is not randomly pulled out of someone's posterior. Another hint: if you look broadly, all animals are to some degree unique. The idea that humans are entirely separate is entirely driven by ideology and religion.

And here again we have left any resemblance of science.

Yes, but the (rough) studies looking at folks with regular church attendance did not really see that (but in some studies the effects i found). My reading is that it might have an effect, but the effect size is small and there are many confounders who can erase any effects.
-
Yes absolutely, there is just a general finding of association, and the speculation of potential protective elements. I am obviously not an expert on this subject, but the few studies I came across didn't delve much into details or spent much effort into identifying confounding factors (the only one I came across was alcohol and substance use). Also, one could speculate that quite a few mechanisms available to struggling folks, are based on religious organizations (more so in the past). One argument made especially in earlier studies suggested that the community afforded by being member of a parish to play a factor, but some studies, including the linked one, found no such correlation.

There is some evidence that religiosity is associated with lower suicide risk, as most religions forbid suicide. The protective factor differed between religions, and I believe the strongest effect was found in Muslims. However, this is not the correct conclusion: The article suggest that in the study cohort, religiosity was associated with lower suicide rates, which is not equivalent to atheists in general conducting at a higher rate. Longitudinal studies who look at large cohort, track suicide rates and then investigate the religious affiliation found contrasting results, and one of the largest ones that I know of (9 yr- over 1 mio folks) found no difference between religious and non-religious groups (https://doi.org/10.1192/bjp.bp.113.128694) There are a few reasons why adherence to religions can have certain protective factors. For example, practicing Muslims do not consume alcohol, which can exacerbate mental health episodes. This would be the same for non-drinking atheists, of course. Other effects that are difficult to disentangle are age, but also overall religiosity of the population (or cohort), as religions can have very different manifestations in difference societies (e.g. in theocracies).

There is a report on pollsters that you can read here. While it does not cover all the details, they refer to sources where the information might be included (or not). https://www.pewresearch.org/wp-content/uploads/sites/20/2023/04/PM_2023.04.19_Polling-Landscape_FINAL.pdf

538 forecasts still put Trump slightly ahead of Harris. https://projects.fivethirtyeight.com/2024-election-forecast/

This is also one of the relatively few examples where we can link a single gene to a fairly clear phenotype (it also affects ear wax consistency). However, I want to reiterate that only because we know one if its associated phenotypes, it does not mean that the phenotype in itself is the trait under selection. While it is possible that body odor is under positive in some and negative in other populations, it is also possible that it is associated with some else that we are unaware of that is being selected, or it could be co-selected with a different allele that we are not considering and so on.

Horrible idea. Think about the risks associated with getting injected with stuff from random people. Moreover, where is the need? Availability of vaccines is not an issue in developed countries, just walk into any pharmacy. Again, think about the issue surrounding administering drugs for a few more seconds.
-
Yes, but one can turn the claim around. For example, mutations in the gene I mentioned earlier (ABCC11), reduces reduces the level of odorant precursors in human sweat. In some populations this variant accounts for over 90% of the population and it was speculated that reduction of body odor might have been under positive sexual selection. This might be an example of such

I have not read the full paper, but based on a skim, I think the authors may have overstretched their claims. To be fair, most of it is in the discussions, which allows for some level of speculation, but this is (IMO) somewhat close to a wild guess. The bacterial enzyme might be an adaption to the human metabolite as it might provide them with a selective advantage. But the analysis would not allow to make any statements regarding this process also being a selective advantage for humans. The authors speculate that the human precursor have no purpose and then speculate on how further processing might have a selective advantage. This is a rather broad extrapolation and would require a much deeper analysis of the metabolic processes leading on the humans side of things (i.e. the precursor). The production of them might not be the primary role of the involved enzymes, but rather a side aspect, that are exploited by bacteria, for example.

Precast, gradient gels in SDS PAGE of proteins
CharonY replied to BabcockHall's topic in Biochemistry and Molecular Biology
I generally do not use precast gels, so I don't have first-hand experience. But I believe that manufacturer generally recommend (obviously) their own loading buffer (LDS). While it is generally recommended to use the same buffer as the running buffer, I believe that most LDS buffer composition are also simple Tris-HCl at pH 6.8. I.e. it shouldn't make much of a difference either way. For power settings, I generally run at constant current as I prefer controlled and more homogenous separation (mostly as I approach this from a 2D perspective). But if your gel are the same size, you can keep the values the same (i.e. 10-15 V/ cm). But depending on the buffer the run time would change. -
I think this is exactly it.

It is pretty much srandard case of an expert talking outside their area of expertise. That being said, it seems the current convention of media is moving towards non-expert talking nonsensense on all areas.

OK, maybe you can tell me what I am doing wrong. Measure twice, cut once. Measure again: darnit. Cut just a little bit more. Hold on, was it inches or cm? Measure again: doubledarnit. Go to Home Depot and get more material and glue. Measure again, oh I forgot the wood screws, why didn't I get them while I was there? Measure once more. Hold on, why is the line not where it is supposed to be? Maybe the pencil sucks. Anyway, cut once. Hold on, why is it too short again? Oh goddamnit, I screwed up the frame in the first place, didn't I? Off to Home Depot, return, forgot the stupid screws again. Just for reference, in the lab I have built devices with <5 micron precision. And they worked! Why am I unable to get 5 cms right? Does this measure tape actually have cm on it?

I am so envious of everyones woodworking abilities. And here I am arguing with contractors about about all the random things they keep destroying for no god reason.

At minimum, interference from that court would need to be more explicitly partisan. Though some might argue that that ship has already sailed.

Changes in high school education and impact on colleges.
CharonY replied to CharonY's topic in Science Education
Found an interesting poll on K12 educators in the US. It is only a snapshot and I have not looked whether there is temporal data available https://www.pewresearch.org/social-trends/wp-content/uploads/sites/3/2024/04/ST_24.04.04_teacher-survey_topline.pdf -
On the one hand Smith made a very strong case by laying out specifically what might be considered official duties or not and the evidence is damning (and public, which is a major point). On the other hand, I am not sure whether it is enough, considering the length SCOTUS already went to derail the case.

Thanks, I am vaguely familiar with major processes in at vents and was under the impression that chemolithoautotrophy is the major mechanism of energy generation (and used for carbon fixation), which is an aerobic respiratory process (e.g. from hydrogen to metals). I was therefore curious about the non respiration part of your comment i.e. whether there are other energy harvesting strategies specific to the vents that I am unaware of (as it is more on the outer fringe of the organisms I know of). Thanks!
