| Why isn't water used in hydraulic applications like vehicles? Posted: 06 Aug 2021 09:55 AM PDT If water is generally non-compressible, why is it not used in more hydraulic applications like cars? Could you empty the brake lines in your car and fill it with water and have them still work? The only thing I can think of is that water freezes easily and that could mess with a system as soon as the temperature drops, but if you were in a place that were always temperate, would they be interchangeable? Obviously this is not done for probably a lot of good reasons, but I'm curious. [link] [comments]  |
| With such a high r0, why didn't measles just burn itself out? Posted: 06 Aug 2021 12:14 PM PDT I've seen speculation floating around the internet that we will get to herd immunity faster with the delta variant because it spreads so quickly, but I wonder even if that is the case, why didn't we develop enough herd immunity naturally for measles to simply burn itself out (for reference, measles has an r0 of 12-18 compared to the delta variant's 5-9.5). I guess I'm generally curious as to why some viruses burn themselves out (or mutate to become far less deadly, like Spanish flu) but others do not. Thanks r/askscience! [link] [comments]  |

| Does human vision have a better horizontal resolution than vertical resolution? Posted: 06 Aug 2021 03:51 PM PDT Does having eyes in a horizontal line result in better horizontal resolution in humans or is it same in both horizontal and vertical directions? Also, what is the aspect ratio of human vision? Is circular, elliptical or something completely different? I have recently studied few video coding standards and wondered why we have more resolution in horizontal than vertical in most standards. [link] [comments]  |
| Does the COVID vaccine inoculate against the RNA sequence or the protein sequence? Posted: 07 Aug 2021 06:46 AM PDT A virus is an RNA, or less commonly DNA, sequence that gets translated into a protein sequence. From what I can remember a virus consists of at least two genes, a polymerase (pol) and an envelope (env). In theory we can have multiple RNA/DNA sequences that code for the same polymerase and envelope proteins. Does the vaccine inoculate against the RNA/DNA sequence or the protein sequence? Also, are there multiple variants of the pol and env genes that code for the same protein sequence? For the virus to replicate, I assume there has to be a certain protein sequence. As the virus replicates it mutates. If the pol gene has a leucine it can be coded by the triplet UUA, uracil, uracil, and adenine. The gene could mutate to CUC, cytosine, uracil, and cytosine and still translate to leucine. This may still be functional, but not be protected against. If the pol and env genes do have multiple DNA/RNA sequences, can we just inoculate against the protein sequence? Would we be able to eliminate the DNA/RNA of the virus with RNAase or DNAase and not damage the protein sequence? [link] [comments]  |
| Do we have any data about how often COVID causes anosmia or hyposmia and how long it tends to last? Posted: 06 Aug 2021 05:43 PM PDT I keep hearing that COVID often causes anosmia and it's usually talked about as occurring in 'mild' cases. As someone who has had long-term anosmia and hyposmia in the past from other causes, this description of the condition... really grinds my gears, I think is the technical phrase. Anosmia and severe hyposmia are debilitating and drastically reduce QOL. If COVID caused temporary - or permanent - blindness, we wouldn't be calling it mild. Anyway, what do we know about the frequency and duration of this symptom of COVID? [link] [comments]  |

| Are there any signs punctuation is simplifying due to social media? Posted: 06 Aug 2021 11:06 PM PDT Is there any sign that English punctuation is simplifying in general from omission/elision in social media due to practical constraints? For example apostrophes and capitalization are often omitted because they take too long to select/type on phones: is this beginning to carry over in an evolutionary (and not just lazy/uneducated) way to English in general?

| How do we know what objects in space are made out of? Posted: 07 Aug 2021 01:44 AM PDT Is it more of a guess or is there a reliable way to figure it out? [link] [comments]  |

| Is the Covid-19 Vaccine the first to be freely distributed in US? Posted: 06 Aug 2021 02:41 PM PDT I keep hearing that the vaccines distributed in the US are the first to be free and make people question the motive. Are there any counterexamples I can give to people where free medical drugs were distributed in the best interest of the population in the US? [link] [comments]  |
| Posted: 07 Aug 2021 05:20 AM PDT I'm sure everyone has heard of Delta. But I am seeing these new variants like "Lambda" and "Delta Plus". I did my own research, and only found how they were made and how people locate them. Not very helpful to my original question. Edit: I live in Illinois [link] [comments]  |
| Posted: 07 Aug 2021 01:28 AM PDT The emerging COVID-19 variants thought out the world are causing a moderate reduction in vaccine effectiveness and capabilities. I am wondering if it's possible to develop a universal COVID-19 vaccine that is able to target numerous of different variants. [link] [comments]  |
| What’s the connection between The Pill and AZ as far as blood clots? Posted: 07 Aug 2021 01:20 AM PDT Is there actually an increased risk of blood clots if someone is taking the combined contraceptive pill and has the AZ vaccine? From what I understand, the potential clots are different types. I.e. DVT vs TTP. Would the clot risk compound or are the 2 things unrelated? [link] [comments]  |
| Is it possible to to model and predict COVID-19 variants and their effects ahead of time? Posted: 06 Aug 2021 11:41 PM PDT And if so, is anyone working on it? I keep reading news all the time like, say, DeepMind's fantastic success recently with using AI to predict protein folding to roughly atomic accuracy. I don't know biology, really, but I gathered that was a big deal. So I wonder: do we still lack the tech and/or knowledge to randomly explore the state space of potential COVID-19 mutations and be able to have a good enough guess at their characteristics that we could flag potential problematic variants for further review? Even if the prohibitive factor is the enormous range of possible mutations, I'd think a random search would be still be useful inasmuch as that's how the actual disease operates, so it could at least hint at which variants are particularly likely to emerge. And it seems like it would be nice to know whether any real monsters are lurking around the corner, if such a thing were possible. If it's not currently possible, why not? [link] [comments]  |

| Does research show that homework does not increase student performance for k-5? Posted: 06 Aug 2021 01:20 PM PDT I realize this question is not in one of the typical hard science fields, but it's still about scientific analysis of learning. In multiple school meetings, principals have told the attendees that research shows that homework does not improve student performance. Homework is a form of practice and suggesting practice does not improve performance is very counter intuitive. Is there actual scientific evidence backing this claim? Or can we challenge the assertion the next time it's thrown out at a school meeting? [link] [comments]  |
