Why do all the planets orbit along the same plane? Posted: 20 Jul 2020 11:42 PM PDT Every model I've seen of planets has them orbiting the sun along the same plane like a Frisbee. Same thing for the milky way, is everything along the same plane? submitted by /u/Nartana [link] [comments]

Why is COVID non-response (asymptomatic) considered a problem for elders? Posted: 21 Jul 2020 08:16 AM PDT I was reading this article in National Geographic, when I came across this quote that I am finding confusing, "...a range of immune responses to COVID-19, independent of age, including one that was essentially a non-response. That lack of response among some older people in the study 'could be linked to immunosenescence,' speculates Michael Betts, an immunologist at the University of Pennsylvania's Perelman School of Medicine..." I understand that means that a vaccine will not be as effective in elders, but wouldn't non-responders be fine, and not necessarily need a vaccine anyway? Because they may be infected but have no symptoms - they'd need to be quarantined until the infection period passes, of course, so as not to spread to others; but otherwise, wouldn't they survive and be just fine?

How do you get one virus to display parts of another virus? Posted: 20 Jul 2020 07:41 PM PDT I read that the Oxford vaccine for SARS-COV-2 used an adenoviral vector expressing the spike protein of SARS-COV-2. How do scientists get one virus to express the spike protein of another? submitted by /u/WeirdWyr [link] [comments]

Will a COVID-19 vaccine have any effect (positive or negative) on cytokine storms that may be occurring in some victims? Posted: 20 Jul 2020 06:00 PM PDT To further expand on the question, it's my understanding that some COVID-19 patients may experience a cytokine storm, where the immune response gets out of hand. Since a vaccine elicits an immune response, would there be a risk of it also causing a cytokine storm, either from the vaccine itself or if the person is subsequently exposed to the virus? Or is there something in the vaccines that would prevent this from happening? submitted by /u/BtdTom [link] [comments]

When a person receives a successful donation, do the genes in the donated body part retain their difference from the host genes over time or is there some kind of assimilation that occurs? Posted: 19 Jul 2020 11:36 PM PDT As an example, if I receive blood donation from someone else. Does that mean my blood now contains blood cells that differ in DNA? If I went for a DNA test would that produce mixed results? Would it be two distinct ones forever or will the DNA mix over time? submitted by /u/CozyAndToasty [link] [comments]

Has there been any further research into the alleged contraindication of Ibuprofen/Advil and COVID-19? If so, what is the current consensus of the scientific community? Posted: 20 Jul 2020 06:23 AM PDT It has been over four months since a widespread belief that Ibuprofen exacerbated symptoms of COVID-19. Shortly after, there were many articles that claimed that many researchers found no such evidence, but at the same time, advised to avoid taking it (if possible) until we learn more. Have we learned more? submitted by /u/ubccompscistudent [link] [comments]

Are traces of Neanderthal DNA found in every single person on Earth? Posted: 19 Jul 2020 11:25 PM PDT I've been reading that Neanderthal DNA is now found in all populations on Earth, including, as it was recently discovered, African populations. I'm confused about this wording. Does that mean every single person you test on Earth will have Neanderthal DNA? Or does this mean that Neanderthal DNA is found in all populations, but not everyone in those populations will necessarily have Neanderthal DNA? Thanks submitted by /u/heavyboi77 [link] [comments]

What would happen to petroleum deposits if they just stayed in the ground for an other million years or so?

Posted: 19 Jul 2020 09:45 PM PDT https://imgur.com/a/f81z8q8 This image is what sparked my curiosity. Since pangea was just a combination of all the continents, or close to that in my understanding, why is it that when the tectonic plates get recycled we still have the same massive continents? submitted by /u/Cliche_Irish [link] [comments]

SARS-CoV-2 is closely related to the original SARS-CoV. How many of the "novel" pathogenic features of COVID-19 were probably also shared by the original SARS (or all coronaviruses), but infections were too few to study? Posted: 19 Jul 2020 08:44 PM PDT SARS-CoV-1 and SARS-CoV-2 are described as being very closely related, but we've still been hearing a lot about new facets of COVID-19, some of them related to how the infection presents, and others related to the actual mechanisms by which the virions replicate. So certain factors appear to be entirely new to SARS-CoV-2 - most important seems to be the pre-symptomatic contagion - but others are maybe not so clear? For example, we hear a lot about how much COVID-19 affects clotting. Is it likely that this contributed similarly to the severity of SARS, but SARS didn't infect enough people to warrant the same degree of scrutiny (and resultant identification of this effect)? In another sense, SARS-CoV-2's use of filopodia to spread infection adjacent cells - do we know if this mechanism was possibly used by the original SARS as well? How likely is it that many coronaviruses can make use of these functions, or affect bodily functions in similar ways, but most just aren't strong (virulent?) enough to do so? submitted by /u/werderber [link] [comments]

When I see a star, did the photons entering my eye actually come from that star? Posted: 19 Jul 2020 09:20 AM PDT Or were they absorbed and re emitted along the way somewhere, such as in the atmosphere? submitted by /u/gargleblast [link] [comments]

To what extent does the increase in testing relate to increase of daily covid-19 cases? Posted: 20 Jul 2020 05:38 AM PDT I'm sorry if this question has been covered but I couldn't find a clear answer elsewhere on the web. It seems as though there has been a significant increase in testing availability over the last couple months and I was just curious if this is driving the increase in new cases we are seeing recently. I was also wondering if publishers of data have some way to adjust their figures to account for increases in testing. Thanks in advance! submitted by /u/Harpua-2001 [link] [comments]

Why do CPUs have a maximum frequency they can achieve even if they are maintained cool? Posted: 19 Jul 2020 03:35 PM PDT So, I've seen a lot of overclocking videos in the past, and have always asked myself the same question: What does 'stability' mean in CPUs/Software? Like, for example, a lot of people have been able to keep it at really low temperatures with liquid nitrogen, but they still can't push, I don't know, say 10GHz on a chip because it's not 'stable enough' I want to know what that 'Chip stability' means, like, the chip can't withstand that frequency? Is it a Software/Windows problem? Both? I want to understand why we can't push them really far even if they're really cool. submitted by /u/DontKnowHowToAdult [link] [comments]

How much does viral load contribute to the severity of symptoms for COVID-19? Posted: 18 Jul 2020 12:39 PM PDT Have there been studies on this yet? For those that have said they had mild symptoms, was this mainly because they were infected with a small amount of virus vs. Someone who say inhaled a lot of virions? Or are severity of symptoms independent of viral load and strictly based upon immune system? submitted by /u/Jimbus88 [link] [comments]

Has scientists exposed the Covid-19 virus to extreme environments to see how strong it is? Posted: 19 Jul 2020 01:28 AM PDT What does a hot environment do to it? At what hot temperature does it die? Can it survive 100C for example? 200C? Etc. Whaf temperature range does it do it's damage the most? What does a cold environment do to it? Will -50C slow it down? Will -100C kill it for example?

Why is flu test much faster than covid-19 test? Posted: 18 Jul 2020 06:19 AM PDT When I take my kids to get flue tests, the results usually come back within half hours. But I have heard that covid tests can last for weeks. What are the main differences between testing flu vs testing covid? Obviously they are different viruses, but in terms of the testing technology, what's the main difference? submitted by /u/ThePiggleWiggle [link] [comments]

Does an ACE inhibitor have an effect on ACE2 receptors? Posted: 18 Jul 2020 06:42 PM PDT Reading about how Covid-19 attacks the body, it seems that the ACE2 receptors are the main entry point of of Covid into the cells. I have no idea if ACE2 receptors are of any relevance to ACE inhibitors but both contain the term Angiotensin-converting-enzyme so I figured I'd ask. I'd assume that difference between ACE and ACE2 makes them completely incongruent. As someone who is taking an ACE inhibitor prophylactically and is otherwise healthy, I wonder if an ACE inhibitor has any effect on my susceptibility to Covid-19. submitted by /u/Special-Bite [link] [comments]

Will related viruses compete with one another in a singular host?

How can the Earth's magnetic field be so weak, yet so large? Posted: 18 Jul 2020 03:35 PM PDT Considering how weak the Earth's magnetic field is, how is it possible for it to have an effect all the way in space; whereas much stronger magnets, like refrigerator magnets and MRI scans, only have a small "effective" range, and doesn't affect global navigation (e.g. compasses) and such? submitted by /u/mimocha [link] [comments]

How come we don't need oxygen tanks when exploring deserts and other areas with little to no plant life? Posted: 19 Jul 2020 03:47 AM PDT I know there's probably a good reason for this that I don't know or haven't researched but honestly I'm just curious. For places like Mt. Everest or other high altitude areas it shows that we need oxygen tanks to survive in those places because of a severe lack of it. If that's the case how come we don't need them in places like the desert or the Antarctic where there aren't any plants to produce oxygen? submitted by /u/Sadashi17 [link] [comments]

What is the excess mortality of the pandemic? Posted: 18 Jul 2020 04:27 PM PDT It's easy enough to see how many people have died, but much more difficult to see how many more have died than were expected?

Is there a chemical that has the opposite effect of capsaicin? Posted: 18 Jul 2020 09:09 AM PDT Capsaicin triggers the sense of burning when it touches tissue. Is there a chemical that has a coldening effect? I don't think I mean like menthol as that seems too brief. But something like it, I suppose? submitted by /u/tehstoni [link] [comments]

Does being very fit for a long period of time cause any permanent beneficial changes to the body, or if you stopped exercising for years will your body end up exactly the same as it would be had you never exercised at all? Posted: 17 Jul 2020 02:48 PM PDT For example, this article suggests (almost) permanent benefits can be realised from strength training in the form of increased muscle nuclei making it easier to rebuild muscle after inactivity: https://www.npr.org/templates/story/story.php?storyId=129359637 How confident are we that this is the case, and have any permanent benefits been identified for cardio training? I'm curious whether the effort put into getting very fit is essentially 'wasted' after a long period of inactivity. submitted by /u/astonewall [link] [comments]

Why does breast cancer often spread to the liver? Posted: 17 Jul 2020 02:29 PM PDT The liver seems to be one of the organs most commonly affected by breast cancer metastases. According to this study, bone metastases (65%) are the most common, followed by lung (31%) and liver (26%). According to my (limited) understanding of human anatomy, the breast does not drain directly into the liver via the portal vein, so I assume if the cancer spreads into the liver via the blood stream, the cancer cells will pass through the lung first. Therefore, my questions are: Does breast cancer spread to the liver primarily via the blood stream? If so, why is the liver affected nearly as often as the lung, although the lung is upstream of the liver and its capillaries should "filter" out cancer cells? Are the cancer cells which make it through the lung simply very likely to get "stuck" in the blood vessels in the liver? submitted by /u/TeaPotChaos [link] [comments]

Black Lives Matter Posted: 02 Jun 2020 10:57 AM PDT Black lives matter. The moderation team at AskScience wants to express our outrage and sadness at the systemic racism and disproportionate violence experienced by the black community. This has gone on for too long, and it's time for lasting change. When 1 out of every 1,000 black men and boys in the United States can expect to be killed by the police, police violence is a public health crisis. Black men are about 2.5 times more likely to be killed by police than white men. In 2019, 1,099 people were killed by police in the US; 24% of those were black, even though only 13% of the population is black. When black Americans make up a disproportionate number of COVID-19 deaths, healthcare disparity is another public health crisis. In Michigan, black people make up 14% of the population and 40% of COVID-19 deaths. In Louisiana, black people are 33% of the population but account for 70% of COVID-19 deaths. Black Americans are more likely to work in essential jobs, with 38% of black workers employed in these industries compared with 29% of white workers. They are less likely to have access to health insurance and more likely to lack continuity in medical care. These disparities, these crises, are not coincidental. They are the result of systemic racism, economic inequality, and oppression. Change requires us to look inward, too. For over a decade, AskScience has been a forum where redditors can discuss scientific topics with scientists. Our panel includes hundreds of STEM professionals who volunteer their time, and we are proud to be an interface between scientists and non-scientists. We are fully committed to making science more accessible, and we hope it inspires people to consider careers in STEM. However, we must acknowledge that STEM suffers from a marked lack of diversity. In the US, black workers comprise 11% of the US workforce, but hold just 7% of STEM jobs that require a bachelor's degree or higher. Only 4% of medical doctors are black. Hispanic workers make up 16% of the US workforce, 6% of STEM jobs that require a bachelor's degree or higher, and 4.4% of medical doctors. Women make up 47% of the US workforce but 41% of STEM professionals with professional or doctoral degrees. And while we know around 3.5% of the US workforce identifies as LGBTQ+, their representation in STEM fields is largely unknown. These numbers become even more dismal in certain disciplines. For example, as of 2019, less than 4% of tenured or tenure-track geoscience positions are held by people of color, and fewer than 100 black women in the US have received PhDs in physics. This lack of diversity is unacceptable and actively harmful, both to people who are not afforded opportunities they deserve and to the STEM community as a whole. We cannot truly say we have cultivated the best and brightest in our respective fields when we are missing the voices of talented, brilliant people who are held back by widespread racism, sexism, and homophobia. It is up to us to confront these systemic injustices directly. We must all stand together against police violence, racism, and economic, social, and environmental inequality. STEM professional need to make sure underrepresented voices are heard, to listen, and to offer support. We must be the change.

Why are diabetics considered to be at higher risk of death from COVID_19? Posted: 17 Jul 2020 04:25 PM PDT My little brother is diabetic, and I was wondering why I read everywhere that people with preexisting conditions like diabetes are susceptible to more severe symptoms of the virus. I understand that a person with a condition that would affect their immune system would have a harder time fighting the virus, but I don't see how a diabetic would struggle with it. submitted by /u/BadassSteve2 [link] [comments]

How likely is it that the modern human genome has genes from other hominids besides Neanderthals and Denisovans? Posted: 18 Jul 2020 05:06 AM PDT Since we've confirmed that early humans interbred with Neanderthals and Denisovans and that some people have genes that can be traced back to them, can we also assume that there are likely other modern genes that were acquired from other hominids we just don't have a fossil record of? submitted by /u/Gradath [link] [comments]

Given two sets of twins (male and female). If each pair has a child, can you determine which child “belongs” to what parents purely from a DNA test? Posted: 17 Jul 2020 07:36 PM PDT As the question implies, if you have two sets of twins (male and female) and each pair has a child, of the same sex or different sex, would you be able to tell what child "belongs" to what parents? If each dad and mom shares identical DNA with their twin, wouldn't these children (who are cousins) be genetically identified as siblings? And in addition, can you tell if there's any genetic difference between identical twins? submitted by /u/amenotekijara [link] [comments]

Has the ratio of Carbon 14 to Carbon 12 in the atmosphere been the same over Earth's history? Posted: 18 Jul 2020 07:16 AM PDT Hi all! I'm curious about the question "has the ratio of C14 to C12 in the atmosphere (1 to 1 trillion) remained a constant across Earth's history?" This came up because I'm active in discussions on Young Earth Creationism. During one of these discussions, I came across this article: https://answersingenesis.org/geology/carbon-14/doesnt-carbon-14-dating-disprove-the-bible/ The main argument in the article is this: Carbon 14 dating is unreliable because assumptions are made about the ratio of C14 to C12 in the Earth's past. Since the ratio could have been different in the past, we can't get accurate readings on the age of dead animals/plants. ​ A critical assumption used in carbon-14 dating has to do with this ratio. It is assumed that the ratio of 14C to 12C in the atmosphere has always been the same as it is today (1 to 1 trillion). If this assumption is true, then the AMS 14C dating method is valid up to about 80,000 years. Beyond this number, the instruments scientists use would not be able to detect enough remaining 14C to be useful in age estimates. This is a critical assumption in the dating process. If this assumption is not true, then the method will give incorrect dates. I also came across a short article that directly conflicts with the above: https://chem.tufts.edu/science/FrankSteiger/carbon14.htm Creationists assume, usually on the basis of a "flood" argument, that there have been large changes in the amount of carbon dioxide in the atmosphere during the past several thousand years. There probably have been small fluctuations, leading to an uncertainty of plus or minus ten percent, confirmed by dating objects of a known age. However, the evidence does not support the creationist claim of large changes in the amount of carbon dioxide. The creationist argument that the ratio of C-14 to C-12 is not constant is actually based on the assumption of a young earth with an age of 10,000 years, and sudden changes in the amount of carbon dioxide in the atmosphere caused by the assumed catastrophic events of the Genesis flood. This is the motivation behind the 30,000 year figure quoted in the creationist position. Creationists attack all radioactive dating with the claim that radioactive decay rates may have been different in the past. There is absolutely no valid evidence to support this claim. It is entirely at odds with everything that is known about nuclear physics. So is the ratio of C14 to C12 over history an assumption? Or do we know that the 1 to 1 trillion ratio has been more or less a constant over the history of life on Earth? If it's not a constant, how to we resolve that and account for the difference when dating fossils? submitted by /u/KittyCatBuddha [link] [comments]

Oxford COVID-19 vaccine, why use a different virus ? Posted: 17 Jul 2020 10:24 PM PDT Excerpt from the article. "The technical name of the vaccine is ChAdOx1 nCoV-19, as it is made from a virus called ChAdOx1, which is a weakened and non-replicating version of a common cold virus (adenovirus). The vaccine has been engineered to express the SARS-CoV-2 spike protein." Question: 1- Why do they have to use a different virus, why not use inert COVID-19 virus itself? 2- Why do they have to engineer a spike protein when COVID-19 already has the spike? https://www.ovg.ox.ac.uk/news/trial-of-oxford-covid-19-vaccine-starts-in-brazil submitted by /u/Infuriorating [link] [comments]

Why does motion sickness cause vomiting?
