Was the 1918 H1N1 virus the "source" for the 1957 H2N2, 1968 H3N2, and the seasonal flu that comes around each year? Posted: 30 Aug 2020 08:55 AM PDT I was listening to a podcast and they suggested that since the H1N1 virus came to be, due to genetic drift and shift, the virus itself has swapped genes becoming H2N2, then H3N2, which also still circulate though out the population. Is this true? I was doing a little of my own research but I am not sure what exact keywords I would use to find an accurate answer. submitted by /u/Farmher315 [link] [comments]

Does the airflow behave differently after Mach 1? If so, how? Posted: 30 Aug 2020 07:41 PM PDT Hello there. Well, the question basically sums it up. I went to a technical school and kind of know how the air molecules behave or "flow" under certain circumstances, but I have no idea nor I was able to find any information about if it behaves in a particular manner after it surpasses the speed of sound submitted by /u/Yo_mamma_said [link] [comments]

What happens to the water that goes inland after a tsunami? Posted: 31 Aug 2020 03:19 AM PDT I saw a short clip of the Japan tsunami and it said it went up to 3 miles in land. The clips show huge quantities of water flooding the towns with buildings almost entirely submerged in water. My question is Where does all that water go? How do towns go back to normal? submitted by /u/JohnyyBanana [link] [comments]

How do scientists find functions in real life? Posted: 30 Aug 2020 08:11 PM PDT In calculus I learned several applications that are used in real life, such as line integrals, doubles, triples, derivatives, vector fields, integral theorems, etc, etc. I recently wondered how much mass a log had that I use to support things. Ok, I use an integral, ahh but I need to know its density function !! And its limits of integration! I learned several interesting things, but I don't know how I could apply them, because for almost always a function is needed. ​ For example I want to calculate how much mass a train track has, for this I need to know, for example, with a double integral, how is the density function and then how are the limits of integration in expressions of x, y, z. (what is this? A cylinder? With a domain with holes ?! and then two planes ?! and for a anvil? They are very rare shapes) or I want to calculate the volume of a chair, how the **** do I do it? It is composed of cylinders, but then it has strange shapes that I do not know of any function like that Or worse, if I want to calculate how is the work that the river does to a flower that I threw, I would need to find the vector field "river". Is that how they do it? do they find functions? do approximations like Taylor polynomials? integral theorems? (even there it is necessary to know how the functions are) Sorry if I write too much, I would be happy to hear from your answers or comments submitted by /u/AlePaff [link] [comments]

When a chemical reaction is “slower” than another, what actually takes more time to happen? Posted: 30 Aug 2020 01:38 PM PDT In other words, is it just the moving of atoms to different places taking longer or is it something else? I know reactions require the molecules involved to hit each other with the correct orientation and amount of energy, so is that just less likely in slower reactions and it takes longer for that event to happen? submitted by /u/AUpballa [link] [comments]

Is there anything that can ONLY be seen in peripheral vision, no matter what? Posted: 30 Aug 2020 02:51 PM PDT So I know that we can see better in the dark (albeit in black and white) in the corners of our vision, but the things we see in these cases - the things that we can't see when viewing head-on in darkness - are always visible when lit up. To my knowledge, at least. Could or are there any objects that can only be seen in peripheral vision? If not in reality, then what would it take for a phenomenon like this to occur in a sci-fi setting? submitted by /u/notwhatimeanbutok [link] [comments]

Role of sun in eye evolution? Posted: 30 Aug 2020 08:45 AM PDT Solar radiation that reaches the earth is predominantly UV, visible, and IR radiation. As visible accounts for the largest part of the radiation, it makes sense that we evolved to perceive visible wavelengths through eyes. Why don't we see IR radiation? Is it because at some point of evolution we (whatever thing we were back then) were able to see it but evolution phased it out because it's not really beneficial for our survival? There are still some animals who can sense IR radiation. If sun radiation is predominantly X-ray we would have evolved X-ray vision? Most of the UV radiation is absorbed by the ozone. If this is not the case if all the UV radiation reaches earth, would we have evolved into beings who don't have negative health effects because of UV or life on earth would not have been possible? submitted by /u/bananapen [link] [comments]

What are the molecular characteristics of air pollution-tolerant plants/trees? Do they have higher expression of antioxidants or terpenes? Posted: 30 Aug 2020 01:32 PM PDT submitted by /u/inquilinekea [link] [comments]

Has there been an observation of the difference in problem-solving skills in a person who has been not been given guidance but still solves a problem, and a person who has been given guidance? If so, how were the observations? Posted: 30 Aug 2020 03:35 AM PDT submitted by /u/lazypawtato [link] [comments]

Does global warming effect the frequency that we will see rare cloud formations? Posted: 29 Aug 2020 02:59 PM PDT As the Earth's climate changes, will we see rare formations become more frequent, and inversely will our currently common cloud formations become rarer? I have seen a lot of cool clouds is recent posts across several subreddits. I understand that this is probably just a internet trend but it got me thinking. submitted by /u/DukePhelan912 [link] [comments]

Why do there seem to be so many meteors rich in iron and not gold or copper or some other metal? Posted: 29 Aug 2020 06:01 PM PDT Meteors seem to sometimes be iron globs. What's do special about iron? submitted by /u/Treefrogprince [link] [comments]

Since we as humans perceive different light spectrums, are there celestial bodies in the universe that are out of our light spectrum and can't percieve? Posted: 29 Aug 2020 05:06 PM PDT As the question states, so we can perceive only a distinct spectrum of light, is there a possibility that there are celestial bodies out in the universe that we humans can't see? And if so how do we know if they're there or not? submitted by /u/shogunhitotiri [link] [comments]

How does antigen binding of the ectodomain of CARs cause changes in the (CD3) ζ signalling tail to permit signal transduction? Posted: 30 Aug 2020 04:58 AM PDT I was under the impression conformational changes in the antigen binding site make their way down and cause conformational changes in the endodomain to permit activation. However, I fail to see how a modular construction of the receptor in the case of CAR would lead to the same event? Is the intermediate linking part of the receptor unimportant and as long as a ligand binding domain is linked to a signaling domain activation is possible? TLDR: How does the endodomain know that the antigen binding domain is linked to an antigen? submitted by /u/GauntherODimm [link] [comments]

What is the difference between Hydrogen and Protium? Posted: 29 Aug 2020 09:48 AM PDT Protium is an isotope of hydrogen but the atomic structure seems to be the same as hydrogen everywhere I look ( 1 proton, 1 electron, no neutrons ).

How did NASA and/or spaceX control the landing of robots like Opportunity and Curiosity on Mars when the signal need over 3 minutes to arrive? Posted: 29 Aug 2020 05:39 AM PDT I assume they controlled something since lots of people were on the computer when they landed. Was it all just automatic? It's like gaming with 180 000 ms of ping. F Same goes for general space exploration. Do scientists here on earth have to wait 2*distance/(light speed) to see their effect on the craft when they send a command? Maybe it's programmed like: if (passed saturn) { turn around and take picture of big planet } submitted by /u/Hello_Its_Microsoft [link] [comments]

Do endocrine disrupters have a permanent effect or do you recover hormonal balance after excretion and reducing exposure? Posted: 28 Aug 2020 07:02 PM PDT BPA and phtalates are very common among the products we use everyday. If you were to be more aware of them and reduce exposure, would your body adjust hormonal balance to a point before being exposed to these chemicals or do they damage the organs which produce hormones physically? submitted by /u/roadmaptonowhere [link] [comments]

How do non-nuclear organelles replicate during mitosis? Posted: 28 Aug 2020 12:39 PM PDT When learning about cell replication, we learn how the DNA itself is replicated in interphase and how the DNA is devided beteeen 2 new cells in mitosis, but what about the rest of the cell's organelles besides the nucleus? Are they replicated and divided within the process or mitosis? Are they created after cytokinesis through coding from the DNA? How long after cytokinesis does the cell actually begin carrying out its normal cell processes? submitted by /u/catzandplantz [link] [comments]

Why does the Covid Nasal Test have to be so invasive? How is it necessary to dig that deep? Posted: 29 Aug 2020 12:17 AM PDT Ouch! Why?! I don't get it, if the germs are in the air, living on objects for days, just everywhere and insanely contagious why dig so deep to test us? If I was infected and picked my nose and wiped it on you, wouldn't you be pretty certain to contract it? Wouldnt the boogers in the front of my nose have covid bacteria too?

Posted: 29 Aug 2020 07:02 AM PDT Maybe I just haven't found an accurate animation or image, but all the ones I have seen already have the beginnings of the Gulf of Mexico shortly after Pangea started breaking up which was about 200 million years ago. submitted by /u/grandchester [link] [comments]

How do robins find the worms? Posted: 28 Aug 2020 11:57 AM PDT My yard frequently has robins hunting in it, and they always have the same basic method. They scurry around, then stop for a while, looking at the ground occasionally tilting their head from side to side. Then they either scurry to a new place, or rapidly pounce and pull a worm out of the ground. How do they do it? Sight? Sound? Some sort of arcane worm summoning ritual to bring Shai-hulud to the surface? submitted by /u/manachar [link] [comments]

Is the research going into a vaccine against Covid19 likely to help us against other diseases? Posted: 28 Aug 2020 08:36 AM PDT I've read that there is being developed vaccines against Covid19 using technology which is new for vaccine used in humans, and that made me wonder if all the research going into finding a vaccine against Covid19 is likely going to lead to significant improvements in the search for vaccines for other diseases - or if two diseases have to be extremely similar for that to be possible, so the influence of the Covid19 vaccine on other vaccine research will be negligible. submitted by /u/Vinternat [link] [comments]

Can natural elements be created the same way that man-made element are? Posted: 28 Aug 2020 02:43 PM PDT Its my understanding that man-made elements (such as Californium and Einsteinium) are created using a particle accelerator, nuclear reactor, or the explosion of an atomic bomb. Can naturally occurring elements also be created in the same way? For example, iron or gold? I've heard that all the natural elements beyond lithium were all created in supernovas and such. But could they also be created in a particle accelerator, for example? submitted by /u/tesuji42 [link] [comments]

What causes diurnal temperature variation on the south pole during its polar winter? Posted: 28 Aug 2020 10:10 AM PDT I see that there is a 8C (15F) temperature difference between the daily highs and lows on the south pole during the winter months. Considering that the sun would be far below the horizon, what causes this? submitted by /u/dodsu [link] [comments]

Why did they have to put the Large Hadron Collider right next to Geneva? Posted: 28 Aug 2020 11:12 PM PDT Bad things aren't supposed to happen, but we have been wrong before! Why take the risk?

AskScience AMA Series: We're are cosmologists at the online Cosmology from Home 2020 conference, ask us anything! Posted: 28 Aug 2020 04:00 AM PDT We are a bunch of cosmologists all currently attending a large online cosmology conference Cosmology from Home: 2020. We have a wide variety of expertise within cosmology, from very theoretical and speculative early universe models down to the detailed observational analysis of data from large telescopes (and most of the evolution in between). We're keen to answer questions about what the state of cosmology is in 2020, e.g.: what are the questions we're currently trying to answer where do we see the field moving in the near future what recent developments got us to where we are in 2020 how do you run a large research conference during COVID19 You can still ask all your burning questions about general cosmology, but seeing as we're all at a conference where people are presenting their present-day research we thought we'd try to frame the AMA towards that present-day state of cosmology. We'll start answering questions from ~7pm GMT (3pm ET/12pm PT) as well as livestreaming our discussion of our answers via YouTube (link coming soon!). submitted by /u/AskScienceModerator [link] [comments]

Can Black Holes Evaporate Into Neutron Stars? Posted: 28 Aug 2020 05:05 AM PDT I'm very much a lay-person in science, so all my attempts to Google this answer have directed me to sources very much beyond my ability. My understanding is that a black hole is a very dense thing, and that a neutron star is a less dense thing both caused by collapsing stars that no longer have enough outward force holding up their massive mass. (Forgive me if I don't use any correct terminology). Well, if a black hole can slow evaporate by losing particles through Hawking Radiation does that mean it can one day lose its denseness and become something like a neutron star. Or once something has collapsed to a density of a black hole is it stuck in that density forever? If I got the smallest possible black hole and using magic split it in half so it contained half the mass, would it continue to be a black hole or would it eventually have enough outward force to "uncollapse" and stop being so dense? Thank you submitted by /u/DStaniforth [link] [comments]

If water is made up of 2 atoms of hydrogen & 1 atom of oxygen, then why can't we manufacture water? Posted: 27 Aug 2020 11:06 PM PDT They say 1 unit of water element = 2 atoms of hydrogen+1 atoms of oxygen.

Why are facial recognition algorithms "racist"? Posted: 27 Aug 2020 12:18 PM PDT I have heard that facial recognition algorithms have more false positives for black and Asian faces than white faces because of the way they are programmed. However, surely there SHOULD be more false positives for Asian and black faces? I'm not trying to be racist here, but they are much less varied than white faces, especially in photos where the resolution may not be great. In a photo any blemishes, flushes, spots, freckles, or other unique facial features show up much more clearly on paler skin. As well as that there tends to be more variance in eye and hair colour in white people. So shouldn't a higher false positive rate be expected in these groups? submitted by /u/noithinkyourewrong [link] [comments]
