How dense are asteroid fields and would they pose a problem flying through? Posted: 30 Aug 2021 04:45 AM PDT I was watching StarWars episode V and was curious if asteroid fields were seriously that dense?

Why do surgeons use intermittent pneumatic compression devices even during short surgeries? Posted: 29 Aug 2021 09:03 PM PDT Sorry if this is the wrong subreddit. A couple years ago I had a surgery that only lasted about 1.5 hours, but my surgeons put an IPC machine (the leg squeezy thing that prevents blood clots) on my legs anyway. wouldn't it take more time to develop a blood clot than lying down for a few hours? Is it more of a liability thing? submitted by /u/violinwitch [link] [comments]

Is it possible for the delta variant to only infect a vaccinated individual's nasal cavity? Posted: 29 Aug 2021 07:18 PM PDT I've been reading how a lot of vaccinated people are testing positive with typical sinus infection or cold symptoms. They have some congestion and sinus pressure, may lose their sense of smell, but that seems to be the extent of their symptoms. Many people seem to think it's just allergies. From some research, it seems like the vaccine promotes IgM antibodies, but IgA antibodies which reside in mucosal surfaces fade quickly. Is it possible that an individual could be infected where they get exposed to the delta variant, but because of IgM antibodies it stops in the nasal cavity, which is why the symptoms seem to be less severe in vaccinated folks? Would this also prevent long covid if the virus never can inflict damage to other organs? submitted by /u/protrader305 [link] [comments]

Why EXACTLY are Category 5 hurricanes classified AT 157 mph? Why THAT number exactly? Posted: 29 Aug 2021 07:44 AM PDT So with Hurricane Ida impending, I was curious as to why the Saffir-Simpson Hurricane Wind Scale appoints hurricane category cutoffs like it does? I understand damage proportion and know the scale does not account for storm surge, flooding, or tornadoes. Thanks! submitted by /u/WraithsRevenge [link] [comments]

Why was Cassini destroyed and Voyager not? Posted: 29 Aug 2021 12:32 PM PDT So I know the Voyagers are still controlled by NASA but after they run out of fuel and stop sending information, isn't it possible that they could hit a planet and contaminate it with bacteria from Earth? We don't know what exactly the spacecrafts could find there because that area is so unexplored, so what if there is a planet with a chance of supporting life? It's like the Cassini mission, where they sadly destroyed the spacecraft because they didn't want to risk a collision with Enceladus or Titan and contaminate it with Earth bacteria. But NASA won't destroy the Voyager spaceships, so isn't that risky? I know that technology wasn't as developed when they launched them as it is nowadays, but NASA took the mission not to affect other worlds and let them in their natural state. It has very low odds to happen but still, what if they crash in an Enceladus-like world and possibly contaminate it? That would basically break NASA's vow not to affect other planets and so. Would it have been better to end them like Cassini to avoid this possibility? Is it possible though? (ok that's a lot but these questions have been troubling me for quite long :)))) submitted by /u/Andreea_Tornado [link] [comments]

Do hurricanes hit the east Atlantic? Posted: 29 Aug 2021 07:38 AM PDT We always hear about hurricanes in the Atlantic hitting the east coast of the US, Caribbean, etc. The west side of the Atlantic. But I can't remember ever hearing about them hitting the west coast of Africa or anything like that. Is that just US focusing on US and not talking more about the outside world, or do they really hit over there more rarely? And if so, why? submitted by /u/prncrny [link] [comments]

What material would break the loudest? Posted: 29 Aug 2021 02:12 AM PDT I was wondering, if loudness of breaking things is somehow connected to their hardness. In that case, a diamond rod (for example) would be unbeatable in terms of sound? submitted by /u/teh_biggy_bunny [link] [comments]

Can infinite ordinals include negatives? Posted: 29 Aug 2021 06:28 AM PDT So for example can one have the ordinal number omega - 1, which comes immediately before omega, or omega2 - omega, which would be somewhere between omegaarbitrarily large number and omega2? Or omegaomega + omega3 - omega*4 + 5? Or must Ordinals be strictly increasing? submitted by /u/Ixthos [link] [comments]

Why can’t fish get rabies? Posted: 28 Aug 2021 03:07 PM PDT Hi all, Aquarium enthusiast and 2x rabies shots recipient. I have lived dangerously so to speak, and lived! But I have a question for you all. I was at my local fish store joking with the owner who got gouged by one of his big fish (I think a cichlid). I made a joke about rabies and he panicked for a brief moment, until I told him it's common knowledge that fish don't get rabies. I was walking home (and feeling bad about stressing him out!) when I started to wonder why. For instance, the CDC says only mammals get rabies. But there's a case of fowl in India getting rabies. I saw a previous post on here that has to do with a particular receptor that means birds are pretty much asymptomatic and clear it if exposed. Birds have been able to get it injected in lab experiments over a hundred years ago. I also know rabies has adapted to be able to grow in cold-blooded vertebrates. So, what about fish? Why don't fish get it? Have there been attempts to inject fish in a lab and give them rabies? Or could they theoretically get it, but the water where they bite you essentially dissipates the virus? Or is there a mechanism (e.g. feline HIV —> humans) by which the disease can't jump to fish? Thanks for any insight. I will be watching Roger Corman's "Piranha" while I wait on your answers. submitted by /u/AquariumBill [link] [comments]

Why does the Watermelon mosaic virus cause a ring/ripple pattern, skipping some tissue ? Posted: 28 Aug 2021 11:48 PM PDT It looks like it's spreading from a center point but skips some tissue and leaves gaps - what mechanism would cause this ?

Would having strong preexisting T cell immunity result in lower antibody levels after getting the (inactivated) vaccine? Posted: 29 Aug 2021 07:05 AM PDT For the inactivated coronavirus vaccine. Pretty much the title. As in; if you have strong t cell immunity before vaccination would that cause the killer T cells to destroy the viral particles from the vaccine faster and more efficiently so there would be less antibodies produced? submitted by /u/wellimoff [link] [comments]

Learning about Botany and discovered Carl Linnaeus. I discovered he named and classified over 7000 plants, but I was wondering if he had any "special" plants that held value to him? Where there any plants that were special or important to how he decided to name things? Posted: 28 Aug 2021 11:27 AM PDT I just really got into Botany and love it. I can't help but appreciate all the hard work that has gone, goes, and keeps going into taxonomy, and I think it's really neat/classy how if a plant was named by Linnaeus it just gets an "L." instead of a name (just a plant thing and not an animal thing which is even neater to me but I digress). I'm kind of interested in him and I'm interested if there were any plants that held significance to him for helping him with his naming conventions. Also maybe just wondering if he had some plants he really liked, even on a personal level. More generically if there are any good videos or guides about Carl. Sorry if this is more of a history question, but it seemed like the people who would be knowledgeable about this would be botany majors way more than history majors. submitted by /u/ManInBlack829 [link] [comments]

What is a good beaker specifically for use with laboratory hot plates? Posted: 28 Aug 2021 03:53 PM PDT Apologies if this barely skirts by the rules of posting, but I couldn't find a more relevant subreddit. I recently purchased a hot-plate, and it gets plenty hot, but it can't seem to properly heat my solutions. I've pretty much narrowed it down to my beakers having exceedingly poor surface-contact with the hot plate. Any suggestions on beakers with nice flat bottoms to avoid this issue? Water/oil baths are not practical. submitted by /u/LOJABE [link] [comments]

Why do tectonic plates "float" on magma and not sink? Posted: 27 Aug 2021 10:46 PM PDT Every explanation of plate tectonics begins with the phrase "the plates float on a layer of magma". And generally speaking the solid form of a substance tends to be more dense. Therefore, shouldn't the tectonic plates sink, form a new cooled crust, then that would sink, etc...? I assume I am missing something fundamental here. Please educate me. Edit: I am trying to be polite about this, but the more I look into it, the less I find and the more I seem to get veiled mocking for even asking the question. If it's so damned simple, would someone please just explain it. Its not like I'm asking you to teach our nations children to read or unify Feynman's work with the new testament. submitted by /u/NuncErgoFacite [link] [comments]

Is there a known correlation between having sensitive skin or problematic skin in general and having a psychological disorder such as anxiety disorder? Posted: 28 Aug 2021 03:19 AM PDT I had this (stupid) thought. Skin is the biggest organ and the nervous system is connected to our brain and our body, so i thought that people who have an extra "nervous" nervous system might have "extra nervous" skin too? Like being more prone to have skin problems? I know there are a few known correlations like people who have OCD (and wash their hands often) are often having sensitive skin, due to all the washing, but i thought more in general..

Do new covid-variants need new antibodies? Posted: 28 Aug 2021 07:59 AM PDT Suppose one is fully vaccinated (lets say with J&J, which has low delta-protection), but nonetheless becomes infected with the delta variant. Would that require a new set of antibodies and hence a new set of B-cells? In my logic, that would mean a much milder illness due to the suppression of virus by initial antibodies, but nonetheless a minimum disease period of 7-10 whilst the new B-cells are developed? Bonus question(s): does everyone make the same antibodies from the same vaccine and does each individual make more than one? submitted by /u/aCityOfTwoTales [link] [comments]

Why are some species of jellyfish only deadly in the tropics? Posted: 28 Aug 2021 04:08 AM PDT I have read that some species of cubozoa jellies (specifically Morbakka Fenneri) live in both tropical and temperate waters, and the first aid response is different for a sting from the same jellyfish species. A sting by this jelly in temperate waters calls for only mild first aid, whereas a sting in tropical waters calls for immediate medical attention for possible irukandji syndrome. How does this work? Can the jelly only produce toxin in warm waters? Or is it to mitigate a case of possible misidentification of more deadly species? Thanks! submitted by /u/billgreg0000 [link] [comments]

Is Quantum Mechanics compatible with relativity of simultaneity? Posted: 28 Aug 2021 01:14 AM PDT I don't know much about QM, but I've heard it has a lot of "truly random" phenomena. If so what are these and are they compatible with the b - theory of time that relativity of simultaneity suggests? Im wondering if someone from a certain reference frame "A" was moving such that he could witness the future of a random quantum event in reference frame "B" could travel to reference frame "B" and predict the outcome of the random quantum event.

What is the biological basis for the "pant tugger" behavior in tree squirrels? Posted: 27 Aug 2021 11:58 PM PDT As a general rule, squirrels are - like many rodents (and other small mammals) - afraid of humans. While in some urban and suburban areas where contact with humans is frequent (e.g., parks, college campuses) squirrels may not flee when a human approaches, in the wild, their natural instinct when we or another large animal or object approaches them is to run away. But from time to time you hear stories of wild squirrels that will follow humans around incessantly, usually when the "following" squirrel is either a juvenile or a mother caring for a juvenile. This story from 2019 was widely reported on, and here's another from last year. A few isolated incidents could be written off as just erratic behavior, but looking into it more, this is evidently a fairly common phenomenon, common enough that wildlife centers often discuss it with specificity (see this example from Toronto, Canada), and it is a recurring topic on web forums and social media (for example, from within the past year alone, here's a post from May, and here's a Reddit comment discussing it from October). It thus seems to be a behavior that tree squirrels exhibit (under certain circumstances) as a species rather than aberrational behavior in a few individuals. The most common scenario by far seems to be when a young squirrel's mother is killed or abandons it. The juvenile squirrel will gravitate to a human and follow them around at great peril, exactly the opposite of the normal "flight" response you would expect. The usual interpretation is that the "pant tugger" / "pant hugger" squirrel is essentially desperate and looking to the human for help, but this could be us inferring too much about an animal's "motives" (for lack of a better term). I am nevertheless very curious about what the basis for this behavior could be! What would be the evolutionary benefit of it? Is it unique to squirrels or do other rodents (or other animals generally) exhibit it? Is the drive to just seek out the nearest warm-blooded thing or is it a unique behavior evolved alongside humans? (I have never heard of this behavior exhibited towards a non-human species, but of course we have selection bias there given that only humans could report on it in the first place!) submitted by /u/chainsawinsect [link] [comments]

Why is the south pole so much colder than the north pole?

Why do Cranes (Family Gruidae) have red-topped heads? Posted: 27 Aug 2021 09:25 PM PDT I am a recent Zoology graduate, and I can rationalise many things with animals, but trying to find an answer to this seems impossible. So many crane species have a head with a red-top, is there an ecological significance to this I am missing? I would assume it's something related to mate-signaling but I am massively bothered by the fact that, over my life as an animal enthusiast, this is the only question I can't find an academic answer or even credible allusion to why on earth these birds have little red caps on them. submitted by /u/6multipliedby9is42 [link] [comments]

During the cruise we have used all this equipment to explore the deep sea through mapping, imaging, and sampling the seafloor and water column. We've seen cold-water corals, sponges, fish, sea cucumbers, anemones, mud and rocky substrate! This cruise is part of the EU Horizon 2020 project iAtlantic. You can read all about the cruise on our expedition website where you can meet the team, learn about our scientific missions and equipment on board as well as catch up with the latest news at the expedition blog. You can also follow us on Twitter, Facebook, and Instagram. We will be here from 17:00-19:00 UTC (1-3 PM ET) to answer your questions about scientific cruises, the deep sea, and ocean exploration.

Does exposure to COVID-19 after vaccination extend the immunity received from the vaccine? Posted: 27 Aug 2021 06:39 AM PDT From what I understand, the immunity provided by vaccination lessens over time which is why a booster shot is going to be offered (at least for Pfizer). However, if a person who is vaccinated were to begin going out to public places a short time after receiving the vaccine in such a way that they are regularly exposed to the virus but not necessarily infected, would this preserve the immunity received from the vaccine? submitted by /u/comdoriano [link] [comments]

When the LHC first started the beams had 3.5TeV per beam but the heaviest particle discovered is 173GeV. Since they're upgrading, does that mean no new particles have been found between 173GeV and 7TeV? Posted: 27 Aug 2021 04:13 AM PDT submitted by /u/ThePigDot_26 [link] [comments]

Are there any patents on the covid vaccine or are all companies sharing "open source" tech at this point? Posted: 26 Aug 2021 06:16 PM PDT submitted by /u/t0xicmarie [link] [comments]

What happens when you blue shift into a gamma ray so much that it should turn into a particle anti particle pair? Posted: 26 Aug 2021 05:05 PM PDT I was wondering what would happen in a scenario like this. Once a photon gets enough energy it turns into a matter antimatter particle pair, and when you move in the direction of something that ejected a photon, that photon blue shifts for you to keep the speed of light constant, gaining energy. So what would happen? How could it be a particle pair relative to you, but a photon to an outside observer? submitted by /u/Potatoboiv2 [link] [comments]

Are venomous snakes born venomous? Posted: 26 Aug 2021 02:09 PM PDT I was wondering if a newly hatched cobra would be venomous, or does it take time. Do they need their fangs to form first? Do they become venomous after going through snake puberty? submitted by /u/Bobby_-_D [link] [comments]

How much similar (or dissimilar) is the mechanism of "immunity - development" in the human body, caused via a 'natural infection' and an 'whole-virus type Inactivated vaccine'? Posted: 27 Aug 2021 12:08 AM PDT submitted by /u/nimitpathak51 [link] [comments]

Arc length: linear vs curved ? Posted: 26 Aug 2021 02:08 PM PDT Regarding the Crinkle crankle wall, Is it true that it uses a less number of bricks compared to standard linear brick wall? If I consider a brick wall ranging from x=0 to x=2\pi, the arc length, L, I'd get for the two cases would be Linear : L = 2\pi = 6.2832... Sinusoidal curved : L = 4\sqrt(2)E(1/2) = 7.6404... ; where E(m) is the elliptic integral --- Curiosity, driven by a simple problem coupled with insightful discussions on math stack exchange. P.S I really wanted to typeset math here, but I am struggling to do so... Thank you submitted by /u/kedarsb [link] [comments]

How do kernel programmers access software interrupts while writing code in C? Posted: 26 Aug 2021 06:56 PM PDT Additionally, is there any mechanism in place to prevent someone from writing an ordinary program that, when compiled and run in user mode, prevents it from hijacking this same functionality and entering kernel mode? submitted by /u/The_Drunk_Dutchess [link] [comments]

Can cold temperature negatively affect a magnets strength/performance? If so how? Are those effects permanent? Posted: 26 Aug 2021 03:08 PM PDT Hi all! I just found this site, that states Ferrite-Magnets must not get colder than -40 C. I can't find any explanation for this online. One site I found briefly mentioned something about electron spins being affected at low temperatures, weakening magnets, but that's all I could find. I understand how heat affects them, at least good enough to be content, but I can't wrap my head around how cold could have a negative effect. Thanks for anyone wo read my question and thanks in advance for any answers. submitted by /u/GiantClaw [link] [comments]

Are there any other pairs of diseases like sickle cell and malaria that have unexpected positive interactions? Posted: 26 Aug 2021 07:57 AM PDT "Positive" for lack of a better word, I realize sickle cell is a horrible disease to have that kills infants and young children but confers some resistance to malaria. Are there any other genetic problems or diseases that end up helping against other diseases? submitted by /u/pupperonipizzapie [link] [comments]

Do vaccines (in general) weaken your immune system for the days that your body is building antibodies? Posted: 26 Aug 2021 08:56 AM PDT This has nothing to do with the big C, just a question. What I mean is, is it easier to catch a cold etc. the days after a vaccine? submitted by /u/Adorable-Chemist-444 [link] [comments]

How can we have anti-A and anti-B antibodies at birth (depending on our own blood type) but Rh- folks only develop anti-Rh antibodies after exposure? Posted: 26 Aug 2021 09:48 AM PDT submitted by /u/pomegranatevale [link] [comments]

How do anticonvulsants work? Posted: 26 Aug 2021 04:04 AM PDT I was wondering if someone could explain how medications function to stop seizures. Take for instance benzodiazepines such as Ativan and Midazolam. Do they work by slowing or stopping the seizing process in the actively convulsing body or is it that it slows down or stops the wonky misfiring in the brain that causes the body to have convulsions? Thanks so much :) An always curious ER nurse submitted by /u/StatisticianFine9452 [link] [comments]
