What is the science behind CDC reducing quarantine to 5 days for covid? Posted: 28 Dec 2021 07:27 AM PST The CDC recently reduced quarantine guidelines stating: "The change is motivated by science demonstrating that the majority of SARS-CoV-2 transmission occurs early in the course of illness, generally in the 1-2 days prior to onset of symptoms and the 2-3 days after. ". Sounds good but they don't provide references.

What's the human body tolerance for sustained lateral acceleration? Posted: 28 Dec 2021 02:15 AM PST Hello reddit. I was wondering what the limit is for lateral acceleration for the human body. I'm interested in sustained acceleration, like from cornering at high speed, not in peak acceleration, like from a crash. I would also be interested in repeated short periods of acceleration, so, again, like a car driving around a circuit, but I understand this information might not be available. I've been looking around but there is much more research about vertical and longitudinal acceleration, which is understandable since that's more relevant for aircraft and spacecraft. So I'm having trouble finding what I want. Thanks in advance! submitted by /u/MrTrt [link] [comments]

How sure are we that the "original" virus that causes Covid 19 identified in Wuhan was the "original" and not a mutation of an undetected coronavirus?

How long does it take for a virus to replicate? Posted: 27 Dec 2021 08:37 PM PST Basically, once a virus enters a cell, how long does it take to do its dirty work and rupture the cell and releasing more copies? A few minutes? A couple days? Could it be broken down into essentially a chemical reaction? submitted by /u/cracksintheegg [link] [comments]

Do allergens become less potent over time? Posted: 27 Dec 2021 09:46 PM PST For example, say I'm allergic to dogs, and I visit a friend's house that has dogs and some dog hair gets onto my scarf. I wear the scarf the following week and sneeze a bit more due to the dog hair on the scarf. Then winter is over and I put the scarf uncleaned away until next winter, will I have as much of a reaction from the allergens on the scarf than I did the past winter? Comparing apples to apples and just the allergens on the scarf. Do they lose potency over time as in do the allergens break down or are they just as potent? Corollary? Should I be dry cleaning my scarves every winter? submitted by /u/dtanmango [link] [comments]

Do birth defects cause more preterm births, or do preterm births cause more defects? If the latter, does the rise in preterm births due to COVID mean higher risk for birth defects? Posted: 27 Dec 2021 09:06 PM PST So after a bit of research I've found a few sources00019-3/fulltext) showing that women who had COVID during pregnancy have an increased risk of preterm birth than women who didn't have COVID. And in the conclusion of this study it says "Birth defects contribute to the occurrence of preterm birth", suggesting that it is the birth defect that increases the chances of preterm birth. They found that 3% of full term births had defects and 8% of preterm (2.65x risk). So the question is: do the babies born to a mother who was sick with COVID have a higher risk of birth defects, and that is causing the rise in preterm births? Or are they healthy babies that are just preterm? The easy way to find out would be to see if the rate of birth defects has changed in total or in preterm overall. It the rate of defects for preterm births has not changed (or gone up), that would mean COVID is increasing risk of defects. But if the rate is going down, then COVID is not causing defects and they are otherwise healthy babies. Unfortunately I have not been able to find any data or studies with this yet myself. submitted by /u/Solmors [link] [comments]

What determines the temperature of space? Posted: 27 Dec 2021 11:23 AM PST I read that the temperature of space is -270C, although I can't fathom why an empty vacuum would have a temperature. It doesn't seem like there should be any source of heat or cold to influence this, so ideally, it should be 0. submitted by /u/69420sixnine69 [link] [comments]

Diet planning based on genetic tests or blood genotype tests. Science or scam? Posted: 27 Dec 2021 02:59 PM PST I am wondering is there any sense in ordering genetic tests or blood genotype tests, made by more and more private, commercial genetic laboratories? Is that evidence-based medicine? Or it is simply a scam? For example, today i have seen advertisement: It is a genetic test that allows the determination of a unique nutritional profile and individual DNA diet. The test consists of analyzing 20 genes - metabolism and obesity, vitamin and antioxidant metabolism, and food intolerances. submitted by /u/alfokloda [link] [comments]

How do respiratory viruses spread in the body? Posted: 27 Dec 2021 05:49 PM PST I'm aware that viruses like an influenza or a common cold replicate in the respiratory tract, but my question is what is the mechanism for spreading? Is it confined to locally spreading from one adjacent cell to the next? (Is this how a viruses reaches the lungs for example) or can it get into the blood stream and get transported to other tissues? If for example influenza can't get into the bloodstream, how/does it(?) infect other organs or cause organ failure? I know that some viruses like HIV are found in the bloodstream, so what decides if the virus is able to get into the bloodstream or not? Thank you so much submitted by /u/mostinho7 [link] [comments]

Is grafting plants hybridization? Posted: 27 Dec 2021 09:03 PM PST Is it just hybridization of plants by attaching a branch to a stem? Can almost any plant do this?

Posted: 27 Dec 2021 08:10 AM PST A lower centre of mass for an object (ie) when the centre of mass is near the base of the object ,it has higher stabilty ,now why is this the case? Is it because when the centre of mass is lower ,the potential energy is less ,so it's in a stable equilibrium ? submitted by /u/EulerMathGod [link] [comments]

Does taking two lateral flow tests at the same time have a multiplicative effect on the results' specificity and sensitivity? Posted: 27 Dec 2021 01:02 PM PST I understand the lateral flow tests should, properly administered, detect COVID between 70 and 90 per cent of the time, perhaps slightly higher than that in the early days of syptoms. Let's assume 90 per cent is correct. Does taking two LFs at the same time, and getting 2 negatives, mean you are approx 1% (90% * 90%) likely to have COVID and 99% likely not to have it? If it doesnt work like that, why not? Would taking the second test the next day change the answer? Same questions but in reverse for sensitivity submitted by /u/GooseOfTheLine [link] [comments]

Why do some birds (owls, eagles) have feathers on their legs while others (seagulls, corvids) don't? Posted: 26 Dec 2021 08:15 AM PST Is it to do with flight? Warmth? Other? Does this factor into taxonomy? submitted by /u/fromthemakersof [link] [comments]

How does the immune system determine which anti-bodies are needed to deal with a virus infection? Posted: 26 Dec 2021 07:20 AM PST I guess it tries a lot of different anti-bodies and some will work but how does it tell which are working?

Did the solar panel on the JWST deploy a little earlier than planned? Will that cause problems? Posted: 25 Dec 2021 07:47 AM PST I was watching the live stream, and just as the JWST separated from the last stage and the video was showing it drift away, the solar array deployed. It was pretty clearly a few minutes earlier than expected, and there seemed to be some sudden tension in the audio among the flight control team. Was the deployment early? And, will that cause problems down the line? submitted by /u/TallEric02 [link] [comments]

How many of the single-point failures of the James Webb Space Telescope are already behind us? Posted: 25 Dec 2021 07:27 AM PST I assume there was a bunch of single point failures that could have occured at the time of launch, now there will be a somewhat "easier" period, and there will be another bunch when JWST arrives at the Lagrange point and opens up. At the time of writing this post JWST is ~4.5% of the way to the Lagrange point 2. submitted by /u/Oficjalny_Krwiopijca [link] [comments]

Since JWST will be so far from earth, will we be able to get better distance measurements through parallax from it? Posted: 25 Dec 2021 08:13 AM PST JWST is going to be 1 million miles from earth, much further than ground based or orbiting telescopes. Are scientists planning to use the additional distance to be able to look for shifts in relative positions of objects due to parallax to help us refine distance measurements? Typically we get astronomical parallax measurements from the changing position of the earth through its orbit, but that takes time (6 months). Maybe JWST will help measure distance to short-lived phenomenon? I've heard lots of discussion of how JWST will help image the farthest/oldest objects, but not anything concerning if it can help refine our measurements of closer objects based on it being offset from earth. submitted by /u/notimeforniceties [link] [comments]

Is it true that penguins become "insane," "deranged," or "disoriented" and travel away from their colonies to die, as accounted by Werner Herzog in "Encounters at the End of the World" (2009)? Posted: 24 Dec 2021 11:17 PM PST This moment in the documentary fascinated me, where Herzog shows a penguin stopping in its tracks, and suddenly starts walking alone away from its home or hunting grounds towards the desolate mountains of Antarctica, where it will die. He says that the penguin scientist he talked to (though without directly showing us the scientist telling this) told him that, even if they went out and brought the penguin back, he would just go right back to his death march. I really can't stop thinking about it, it's a strangely, somewhat upsettingly, human behavior that, if is how Herzog describes, certainly appears like the penguins are trying to die. But when looking online, I couldn't find any scientific reports of this behavior, only people referring back to the documentary. The scientist seemed like a real scientist, but there's no information on this I could find. Is there any truth to this? Is this a behavior scientists have observed in penguins, and if so is it as bleak as Herzog describes? submitted by /u/sweaty_garbage [link] [comments]

Do antibodies get used up when preventing an infection? Posted: 25 Dec 2021 04:14 PM PST Suppose I have COVID-19 neutralizing antibodies from a vaccine. I get exposed to SARS-CoV-2, but neutralizing antibodies prevent the virus from reaching my cells. Does that lower my antibody levels, leaving me more vulnerable on next exposure? Would antibody levels drop for other reasons than this? Can the distinction (if this depletion does occur) be measured? submitted by /u/Sgeo [link] [comments]

How do the rapid antigen tests work in depth? Posted: 25 Dec 2021 06:23 PM PST Hi, I was interested in knowing the specifics of how the rapid antigen tests work, I know that they must involve identifying covid antigens but how exactly?

What is going on in the bodies of people with asymptomatic Covid-19? Posted: 25 Dec 2021 02:52 PM PST For the approximately 33% of Covid-19 positive people who have no symptoms (but can still transmit the disease), what is actually happening in their interactions between their immune systems and the virus? If they can transmit the disease to others, the virus must be replicating in their cells; why does this not hammer them with the usual symptoms such as coughing and fever? submitted by /u/gtd98765 [link] [comments]

Fov of a simple eyepiece? Posted: 25 Dec 2021 10:12 AM PST I'm trying to understand these old-style eyepieces where there was only a lens and an aperture at the focal distance of the lens.

Also known as the apparent field of view of a telescope? e.g. https://www.nexstarsite.com/_RAC/articles/fieldofview.htm#:~:text=The%20field%20of%20view%20is,smaller%20piece%20of%20the%20sky.&text=Usually%20astronomers%20refer%20to%20the,field%20of%20view%20or%20TFOV. ​ A diagram to illustrate the problem submitted by /u/Synethos [link] [comments]

Is there a minimum amount of inhaled CO2 required for proper functioning of the human respiratory cycle? Posted: 24 Dec 2021 11:52 PM PST I'm aware of certain levels that need to be maintained in the blood but it is my understanding that this is produced internally. If this is the case would it be safe for me to breath air with a theoretical 0/ppm CO2 composition?

Do Cordyceps tap in to the hosts senses? Posted: 25 Dec 2021 01:19 AM PST I was just watching the BBC Nature doco about the fascinating and kind of scary Cordyceps, and how they take over ants, and make them go to an optimum place then clamp their jaws onto the plant stalk and then the Cordyceps start emitting spores and the whole lovely process can repeat. My question is how does the parasite know when the ant is in the position it wants it to be in, before triggering the next stage (the jaw clamp and spores/growing)? Does it actually burrow into the insects brain and live in it now or is it capable of it's control without doing that? submitted by /u/Y34rZer0 [link] [comments]

Why do some Israeli scientists say a second booster is "counterproductive," and may compromise the body’s ability to fight the virus? Posted: 24 Dec 2021 08:13 AM PST Israel recently approved a fourth dose for the vulnerable citing waning immunity after the first boost. Peter Hotez endorsed a second boost for healthcare workers in the LA Times. This excerpt confuses me though: Article: https://archive.md/WCGDd The proposal to give a fourth dose to those most at risk drew criticism from other scientists and medical professionals, who said it was premature and perhaps even counterproductive. Some experts have warned that too many shots eventually may lead to a sort of immune system fatigue, compromising the body's ability to fight the virus. A few members of the advisory panel raised that concern with respect to the elderly, according to a written summary of the discussion obtained by The New York Times. A few minutes googling didn't uncover anything. I'm concerned because I heard Osterholm mention (37:00) long covid may be the result of a compromised immune system. Could the fourth shot set the stage for reinfection and/or long term side effects? Or is it merely a wasted shot? submitted by /u/Automatic-Mention [link] [comments]

Posted: 24 Dec 2021 10:13 PM PST What makes the vaccine antibodies more robust / diverse than the monoclonal antibodies produced in labs? submitted by /u/Spadunk93 [link] [comments]

Does toothpaste usage alter oral microbiome? Posted: 24 Dec 2021 06:05 PM PST I am unaware of papers that have tested the effect of brushing teeth with or without toothpaste on oral microbiome, but please let me know if there are any. I would hypothesize that the toothpaste would alter the microbiome compared to no toothpaste brushing, as toothpaste is inherently bactericidal and probably temporarily alters the pH of the mouth? There are papers that look into different types of toothpaste on oral microbiome, but I'm not sure how trustworthy they are. The million dollar question would be if using toothpaste alter the oral microbiome for better or worse? Edit: This paper is an interesting read on oral microbiome, does suggest the microbiome is important to tooth health, but still doesn't answer the questions at hand: https://www.nature.com/articles/sj.bdj.2018.81 submitted by /u/DegreeResponsible463 [link] [comments]

Is it possible to catch Covid again immediately having recovered from it? Posted: 24 Dec 2021 04:39 AM PST Say you've completed your 10 day quarantine and recovered from Covid. If you were placed in a room with 5 infected people, would you get it again immediately? submitted by /u/TheGreatRaymondinio [link] [comments]

Do Covid variants "occur" all within one host person or do they likely occur across a group of people? Posted: 24 Dec 2021 04:21 PM PST Given the large number of variations in Omicron, I'm curious if it likely came about gradually across a group of people with new variations occurring as it's passed to new hosts or all variations likely occurred within one person? submitted by /u/RUN_MDB [link] [comments]

Do at home covid tests test specifically for covid-19 or just any coronavirus? Posted: 23 Dec 2021 09:15 PM PST Hi everyone, A friend and I were talking about the at home test for covid 19 and we were wondering if the test are specific to covid-19 or all Coronas in general. We are not scientist and when we did a google search could find a quick answer on reputable sites(like cdc and such). Thank you!!! submitted by /u/Yazzjazzpazz [link] [comments]

Why aren't agonic lines simply the line drawn from magnetic north to polar north? Posted: 23 Dec 2021 07:44 PM PST I was watching a video about magnetic declination and the presenter was describing how there are lines of zero declination (called agonic lines), where you don't need to adjust a compass at all for it to point to true north. That makes sense to me, but when I got curious and looked up NOAA maps that show magnetic declination lines I saw that the agonic lines weren't where I expected them to be, and furthermore they didn't even form straight lines when projected on a globe. Here's a picture of the current magnetic north (as of 2020). If you drew a line through the north pole and the magnetic north pole, and extended it around the globe, it would touch Eastern Russia, and also just west of Greenland. Now here is a map of current declination lines. The weird projection they used makes it hard to visualize on a globe but what's very clear is that there's a big ol agonic line shooting right through the middle of the USA, and that line touches neither the north pole nor magnetic north. There's also a second agonic line that does go from the north pole to magnetic north, except rather than just going straight there it meanders through Africa first! What the heck? Why is this? Wouldn't people in Manitoba have to adjust their compasses quite a bit to point true north? Because according to the map they don't. I don't know what concept I'm missing here but I'm hoping someone can help me out because this just makes no sense to me. submitted by /u/typical83 [link] [comments]

If you've got plugged ears, does a high volume sound still damage the ears to the same degree, even if you can't hear the sound as much? Posted: 23 Dec 2021 01:32 PM PST This may seem stupid, but I had plugged ears (like from pressure changes) today while listening to music and became genuinely curious. submitted by /u/Amaryllis_blooms [link] [comments]

How can we predict solar eclipses? And how were ancient people able to do so? Posted: 23 Dec 2021 11:12 AM PST Just something I've been wondering about for a while now... As I understand it (Thanks, Bill Nye!), the orbit of the moon is "wobbly" and somewhat random. Given that information, how can we accurately predict solar eclipses months, years, and even decades in advance? Additionally, how were ancient peoples able to predict them as well without advanced scientific equipment? submitted by /u/brokenimage321 [link] [comments]
