Why do vaccines provide longer immunity from a virus than natural infection? Posted: 24 Feb 2021 09:38 AM PST I know that the antibodies released by the B cells in the secondary infection will be more specific to the deactivation of the virus for the vaccine compared to natural infection and other advantages like that. However, I couldn't find much when I was looking for the reason that vaccines provide longer immunity, I was only reading how in both cases there will be memory cells for secondary infection. Sources would be greatly appreciated. submitted by /u/Awing9 [link] [comments]

Is it possible to scale down a linear accelerator for it to fit into a spacecraft to power it by firing particles out of the other end? Posted: 25 Feb 2021 12:39 AM PST I was looking at methods of propulsion in space and I was wondering if this was possible. submitted by /u/oh_lyraj [link] [comments]

Do we know the climate of Pangaea? Posted: 24 Feb 2021 08:30 PM PST I was wondering if we know the climate of the supercontinent Pangaea, and if we do know then how do we? I tried looking this up but all I got was weather for my town (probably because they both start with p) and the typical description of "Pangaea or Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras." If anyone can answer this question, thank you! submitted by /u/ILikeBoats01 [link] [comments]

Is it a legitimate claim to say that random, erratic weather is a result of climate change? Posted: 24 Feb 2021 09:57 PM PST I'm just thinking how over the course of a couple weeks we have swung from very cold temperatures on the East Coast in US and now it feels like spring today. So I guess my question is asking if that sharp change could occur under regular weather patterns or is it so because of climate change. submitted by /u/Gsticks [link] [comments]

Dumb question but, how is Caesium just chilling in the ocean after the Fukushima Daiichi disaster? Posted: 24 Feb 2021 01:01 PM PST I read about how Caesium-134 and 137 were found found in the ocean after the reactor disaster. But I thought Caesium will always react violently with water. So what is going on with that? Did it react with something else and won't switch? Sorry this is probably a dumb question submitted by /u/germattack3 [link] [comments]

What would happen if a fully vaccinated individual were to contract coronavirus? Would it just feel like a light cold for them or would they literally not get sick at all? Posted: 24 Feb 2021 10:24 PM PST submitted by /u/Crimson_Carp748 [link] [comments]

What happens when the angular quantum number is greater than 3? Posted: 24 Feb 2021 06:48 PM PST I was learning about quantum numbers, and how the principle quantum number n determines l, the angular momentum quantum number. But when I'm looking at electron configuration for higher elements, it has values of n up 8. This would follow that there are values of l up to 7. The problem is that I'm only taught up to 3 with the f-block. Can someone please explain this? On a related note, what is the purpose of the magnetic quantum number? Does it determine which of the orbitals an electron is in within l? Why are some values of it negative and others positive? Sorry if this is the wrong sub for this question. I just can't find any answers by googling. submitted by /u/ThePlatinumDragon999 [link] [comments]

What is the process for decontaminating sites where nuclear waste is present? Posted: 24 Feb 2021 08:29 AM PST Just wondering the main stages after a nuclear event both long term and after and if there is regulations for it Also any links to interesting videos on the subject submitted by /u/plutonium_77 [link] [comments]

Do nuclear submarines use the hydrogen they get from electrolysis or just dispose of it? Posted: 24 Feb 2021 02:18 PM PST Not 100% sure if this is the right flair, call me out if I'm wrong. I'm curious, since nuclear submarines get their O2 from the water surrounding them do they also use the hydrogen for power or even welding purposes? Or do they have other ways of disposing it? Edit: For some reason I can only see some of the comments... responding is hard when I can't see the comment itself. submitted by /u/Autistic_Lurker [link] [comments]

Virologists- can you please explain why there needs to be a different antibody test for COVID19 when you were vaccinated vs getting the virus from natural infection? Posted: 24 Feb 2021 05:58 PM PST submitted by /u/ThefirstWave- [link] [comments]

Is Adenovirus "escape" from the lysosome into the cytosol species specific? Posted: 24 Feb 2021 08:24 PM PST I am wondering if human adenovirus was endocytosed/phagocytosed, by an amoeba (for example), would it still be capable of escaping the endosome into the cytosol of the amoeba? I looked into the literature and all I can say is that nothing I read suggested that it isn't a generic process that could work on any endosome... but that is far from a satisfactory answer. submitted by /u/Natolx [link] [comments]

Any connection between a shift in the earth's magnetic north pole and the southward Artic jet stream? Posted: 24 Feb 2021 05:08 PM PST Will a shift of the earth's magnetic north pole (from northern Canada to Siberia) affects the polar vortex, if any? Are we going to expect more frequent Artic jet streams pushing southward if so? submitted by /u/0b53rv3r [link] [comments]

How can light speed up when passing from a dense to a less dense medium? Posted: 24 Feb 2021 10:26 AM PST I took a microscopy course recently and have a question related to Refraction. So, I understand that light slows down when passing into a denser medium. This leads to the light being bend at the border of the two media. (Snell's Law of Refraction) This still makes sense in my head. But apparently it can also "speed up" when passing from a dense to a less dense medium? How is this possible? Where does the energy for acceleration come from? I'm studying molecular biology so I don't understand too much about physics ;) submitted by /u/geneKnockDown-101 [link] [comments]

If a hose is against more pressure than what it produces, what happens? Posted: 24 Feb 2021 11:20 AM PST For example, if a hose spews water at a certain pressure, and it is facing upwards in a relatively deep water body, which creates more pressure than what the hose is exerting, what happens? Does the water go backwards through the hose? Or does it simply stop? submitted by /u/Diegootmz [link] [comments]

New flu strains evolve and successfully spread every year. Does this mean flu is getting more infectious every year? Posted: 24 Feb 2021 07:49 AM PST When new strains evolve and spread, this is them evolutionarily out-competing the old strains, right? That is, they're better able to spread their numbers than the old strains are. Isn't this equivalent to saying the new strains are more infectious than the old ones? If so, and this process happens year on year, doesn't that mean the flu virus is evolving to be ever more infectious as time passes? Or am I misunderstand the way new strains work? submitted by /u/Wootery [link] [comments]

Could there be a magnet so powerful that it attracts human beings like an ordinary magnet attracts screws/nails? Posted: 24 Feb 2021 02:25 AM PST I ask because humans contain many metals (iron, calcium, etc.) and also we're like 70% water and I've read that water is lowkey magnetic submitted by /u/ChadMojito [link] [comments]

Why do viruses have different ways on affecting the human body instead of having the same impact altogether? Posted: 24 Feb 2021 01:32 AM PST What I observed on the viruses is that they have unique ways on affecting the human body like for example the COVID-19 virus affects the lungs, kidneys, liver and many more while Rabies affects the brain. What gives them the ability to affect the organs in their own style just like the other pathogens like bacteria? submitted by /u/TheRealWredge2518 [link] [comments]

Why can't we have contagious vaccines? Posted: 23 Feb 2021 09:13 AM PST Unless I'm misunderstanding, vaccines are viruses themselves that trigger an immune response which is intended to protect against a specific strain of a closely related virus. Why can the target be highly contagious, but we can't have a vaccine that is too? Is mutation too much of a risk? submitted by /u/Lookitsmyvideo [link] [comments]

I am considering using electrolysis to remove rust from a pair of antique Wiss Tailors Shears that have a brass shear bolt that is better left in place. Will the presence of brass on the cathode affect the electrolysis process and vice versa? Posted: 23 Feb 2021 10:37 AM PST I am debating whether or not to use Evaporust or electrolysis. My concern is that the brass might split into its component elements or in some other way be harmed during electrolysis. Or would this only occur if the brass was on the anode? Removing the shear bolt is very difficult and replacements are not available in case it is damaged. Thanks in advance.

I have to get the first dose on Friday but I'm pregnant (35 weeks) and just got the Tdap vaccine last Wednesday. It will be day 10 when I'm scheduled for the covid vaccine.

Does ice sublimate in freezers? Posted: 23 Feb 2021 09:40 AM PST I was looking at the phase diagram of water and I don't understand how ice can sublimate in a freezer. At 1 atmosphere and say, -10 to -15C, it looks like the ice would have to melt before reaching the gas phase. Or the pressure would have to drastically drop. Does ice really sublimate in a freezer and if so, how? submitted by /u/Enferno82 [link] [comments]

How do Computers Use Electricity to Complete Computational Tasks? Posted: 23 Feb 2021 08:42 AM PST Whenever my computer or Playstation is "working hard" to complete a computationally intensive task, the fan starts whirring to cool the circuitry inside it. I'm guessing that has to do with the amount of electricity being used to complete the task, which is what's generating the heat, but I don't understand how that electricity is used to fulfill the computing task or why more is required for more difficult tasks. submitted by /u/dyohann3396 [link] [comments]

Are the biological children of gay people more likely to be gay than the biological children of straight people? Posted: 22 Feb 2021 07:24 PM PST When I try searching for an answer, I get a bunch of results about whether gay couples can be good adoptive parents, or the affect of fraternal birth order on sexual orientation. This isn't what I'm looking for. Surely in societies where being gay is taboo, a significant number of gay men end up having biological children due to social pressure. I am curious if these children are more likely to be gay. If so, would this lead to a larger percentage of people being gay in societies where homosexuality is oppressed? That would be ironic. Any sources you could point me to would be awesome. submitted by /u/JamesonLKJ [link] [comments]

The outer planets in our solar system understandably take longer to orbit the sun than the inner planets. Is it possible to have an outer planet that moves so quickly that it completes revolutions more quickly than the inner planets? Or conversely, an inner planet that moves so slowly?

How much of the recent news about magnetic poles flipping is legitimate? Posted: 22 Feb 2021 02:58 PM PST Not sure if this is flaired appropriately, if not let me know. I've been seeing a lot of articles lately about the magnetic poles flipping 42,000 years ago and causing extinctions and such. My prior understanding was that the connection between poles flipping and any sort of catastrophic changes was tenuous and heavily disputed, but it seems like the consensus has changed somewhat. All of this seems to follow a relatively recent study based on fossilized and very long-lived trees in New Zealand IIRC. However, I'm not sure how much of what I'm seeing is legitimate and well supported vs. media doing its thing and my feed reacting to my activity and showing me more of the same. Any insight is appreciated, thanks y'all. submitted by /u/k3kat_aljabn [link] [comments]

Do COVID-19 vaccines prevent Long COVID? Posted: 21 Feb 2021 06:04 PM PST There have been reports that COVID-19 can for some leave lasting damage to organs (heart, lungs, brain), even among people who only had minor symptoms during the infection. [Q1] Is there any data about prevalence of these problems among those who have been vaccinated? Since some of the vaccines, notably the one developed by Oxford-AstraZeneca, report ok-ish efficacy in preventing symptomatic COVID-19, but very high efficacy in preventing severe COVID-19, I'm also interested in how does this vaccine fare in comparison to the ones that have higher reported efficacy against symptomatic COVID-19. So, to phrase that as a question: [Q2] should we expect to see higher rates of Long COVID among people vaccinated with vaccine by Oxford-AstraZeneca than among those vaccinated with vaccine by Pfizer-Biontech or Moderna? submitted by /u/am9qb3JlZmVyZW5jZQ [link] [comments]

What protocol(s) does NASA use to communicate long distances? Posted: 21 Feb 2021 09:32 AM PST I am looking at https://mars.nasa.gov/mars2020/spacecraft/rover/communications/ which talks about how the rover communicated with Earth, which is through the orbiter. I am trying to figure what protocol does the orbiter use? Is it TCP/UDP, or something else? Naively I'd assume TCP since the orbiter would need to resend packets that were lost in space and never made it to Earth. submitted by /u/melbogia [link] [comments]

What kind of distances would you need in order to show that on a sphere, three 90 deg turns make a triangle? Posted: 22 Feb 2021 04:09 AM PST First, yes I know the earth isn't a perfect sphere but it should be close enough for this. So on a "close-enough" sphere, someone should be able to travel some distance, x, make a 90 degree turn and travel x again, make another 90 degree turn, travel x again and return to their point of origin. My question is: what ballpark distance would x need to be in order to demonstrate this? submitted by /u/jradio610 [link] [comments]

Are there more frequently occuring faces? biology/neuroscience Posted: 21 Feb 2021 07:11 PM PST What I mean is, are there more common strings of DNA/genetics to determine facial features than others? Or is it related to how I perceive faces? There have been many times when I see someone and in my head I think they have a "common" face, as in, they share a lot of features and/or a similar composition of those features to a lot of other people I've seen. I don't recognise the person, or think they look average. It's that they just have 'one of those faces' that I see a lot. I'm wondering if this is actually a thing that has been studied on a genetic level, whether certain sequences of dna are more typical than others, or if it may be more or a neurological thing related to how I process faces and interpret/recognise them. If it helps, I also don't see identical twins as being fully identical. I think they look VERY similar but they always look different to me. This could be related if its neurological rather than an actual biological phenomenon. P.S. I don't study science in anyway so apologies if anything I've said sounds dumb haha submitted by /u/abscissioninbloom546 [link] [comments]

If you had a hypothetical indestructible submarine that was pressurized and could drill thru solid rock and you drilled right to the exact center of the earth, how would gravity act on you at that center? Posted: 21 Feb 2021 10:05 PM PST Or would this theoretical submarine break so many physical laws that the outcome is unfathomable? Would you float at that center point? Would you implode into yourself as gravity acts on you from every direction at once? submitted by /u/Snaz5 [link] [comments]

How is it determined if a vaccine reduces transmission of the virus? Posted: 21 Feb 2021 05:36 PM PST Reports are saying that data coming out of Israel shows that the Pfizer / Bio-Tech vaccine is slowing the spread but all I'm seeing in the articles is that it is reducing infection by 89%. How does this relate to the transmission rate? If you are vaccinated and not as likely to get infected, does that automatically mean you are also less likely to spread it?

Why does the theory of general relativity suggest celestial objects operate on a two dimensional plane? Posted: 21 Feb 2021 09:08 PM PST Models, which represent the mass of objects, show that as mass increases, the depression in this theoretical two-dimensional plane increases. I wonder, why does this represention of mass rely on the idea of a this plane? Obviously, the universe is three dimensional, so I can not comprehend the idea of massive objects creating a depression in a two dimensional plane, whch contributes to certain properties of gravity. Unless, this is looked at on a smaller scale, such as a solar system, in which most bodies could be coplanar. For the record, I am not familiar with spacetime curvature, or in depth analyses of Einstein's theories of relativity. TLDR: how do two dimensional representations of three dimensional space time curvature work? How do you break down what exactly the model is showing? submitted by /u/_flipside- [link] [comments]

Which galaxies could we send probes to? Posted: 21 Feb 2021 11:54 AM PST Trying to research this. Usually journalists point out that spatial expansion will make other galaxies unreachable through normal transit (disregarding wormholes or similar possibilities). But that's not true because at least one galaxy, Andromedia, is going to merge with our Milky Way galaxy. Obviously at least one galaxy is accessible. Is Andromeda the only one we could send a probe to? How does expansion figure into this? It would be a one-way trip, but is a window of opportunity to send probes or even spread life to other galaxies closing? submitted by /u/NippleSuckingAsshole [link] [comments]
