Did the ocean go through the same mass extinction 65 million years ago that the dinosaurs also experienced? Posted: 17 Aug 2021 08:52 PM PDT This is just an assumption, but it seems like the deep sea wouldn't get as affected by the so-called meteor then the land would. And even after the meteor strike, I feel like the survival rate would be a lot better in the ocean. And like we have experiences of deep sea gigantism today. I feel like there should just be more deep sea gigantic reptilians as well. I mean like I've heard that like alligators, and sharks and shit have been like around for like long ass times. So why don't we have more like big boys in the ocean nowdays? You know like the size of whales or bigger. submitted by /u/JoeyPepperoni101 [link] [comments]

Why is the Moon's Core Cooling? Posted: 18 Aug 2021 07:29 AM PDT According to NASA, the moon's core is cooling, making the it shrink in size. If the Moon has the same amount of mass with an even smaller diameter, shouldn't the pressure make the Moon heat back up? Also, consequently, get a bit bigger (But that's beside the point)? submitted by /u/TheRealCrazyKingBest [link] [comments]

Can someone help break down this Covid-19 Delta variant vaccine ADE research? Posted: 18 Aug 2021 04:25 AM PDT This article was recently shared with me in an attempt to discourage me from getting my child vaccinated against Covid-19. That biased me against the article immediately, but Journal of Infection appears to be a reputable, peer-reviewed source. At a high level, the article appears to be saying that generation 1 mRNA vaccines show a preference (in a lab environment?) for ENHANCING Covid-19 Delta variant infections. Every news report I have seen up until now has indicated that, although breakthrough infection is more possible with the Delta variant, vaccination has strong co-indications with less severe infection, easier hospital stays, and survival, regardless of variant, so I don't understand what, ultimately, these "Enhancing Antibodies" are doing and whether this actually presents a cause for concern, as Yahi, Chahinian, and Fantini seem to be saying ("ADE of delta variants is a potential risk for current vaccines") or if this simply helps to explain WHY the Delta variant is slightly more likely to result in a breakthrough infection. The conclusion of the article absolutely doesn't support the "don't vaccinate your kid" message of the person who shared it (simply saying more research is needed), as it says more study is needed, but I'd still like to ensure I understand the article correctly. https://www.journalofinfection.com/article/S0163-4453(21)00392-3/fulltext#relatedArticles Edit to fix broken link submitted by /u/thain1982 [link] [comments]

Do all autoimmune antibodies appear on antinuclear antibody titers? Posted: 18 Aug 2021 07:47 AM PDT I'm having difficulties understanding how the suite of antibody tests fit into the diagnostic process for autoimmune disorders. It was my vague understanding that any appreciatively positive result for a specific autoimmune antibody would also correlate to a positive ANA titer (ie, the ANA is a general test and further testing is to specify the type of antibody present). Is this a matter of reference ranges, instead? Is it possible to have an ANA titer below the generally accepted reference range but a specific antibody concentration above its corresponding reference range? submitted by /u/SomethingPunnier [link] [comments]

Where do germs go when they’re killed? Posted: 18 Aug 2021 01:38 AM PDT If there's a table covered with germs, and you spray some disinfectant on it, are the germs still there, but dead? Or does the cleaner make them evaporate? I guess I'm just asking what happens to germs and other microscopic organisms when they die? submitted by /u/Turbulent_Compote_83 [link] [comments]

Why is the Hubble Sphere expanding? Posted: 18 Aug 2021 12:00 AM PDT I've seen several sources that claim the hubble sphere (the point where objects begin to travel away from us faster than the speed of light) is expanding and only say because of the expansion of the universe, but if things are accelerating away from us as well, wouldn't the hubble sphere be decreasing in size? submitted by /u/xVenomDestroyerx [link] [comments]

What type of enzymes break down urine? Posted: 18 Aug 2021 07:29 AM PDT Hi, I find many many products and product recommendations for enzyme cleaners to act upon uric acid crystals (in a word, to eliminate urine stains and smells). But, when I look closer at the ingredients or MSDS data, I find absolute garbage information, like the product is composed of live bacteria, or composed of antimicrobials, or both. Especially with cleaning materials it seems like there is a dearth of clear information available. The best I have found is : https://nationalincontinence.com/pages/removeurine My question: What kind of enzyme(s) are used to eliminate urine stains, and what temperature range, pH range or any other requirement is needed for the compound to work effectively? (I'm happy to referred to a more appropriate sub) submitted by /u/spammmmmmmmy [link] [comments]

How are vaccines tested for efficacy? Posted: 17 Aug 2021 09:34 PM PDT Specifically, I read a story about a new potential mRNA vaccine for HIV that made me curious. I did some googling, but everything said they "are tested" and are "monitored for safety" but I'm curious about the actual methodology used to determine effectiveness. How they test for safety would probably be interesting too, but I'm more interested in the efficacy test Take the HIV example... I mean, you can't exactly just go about giving someone a shot and exposing that person to a potentially-debilitating, very expensive, lifelong, uncurable illness..... can you? And you can't really just let the person go about their life after the shot hoping they're exposed to the disease and call it a success if they don't get sick. So, how do they actually test the vaccine? submitted by /u/UnkindPotato [link] [comments]

What are the primers for SARS-CoV-2 PCR testing? Posted: 18 Aug 2021 06:49 AM PDT TaqMan? SYBR Green? or is it not standardized? submitted by /u/squirrelynugget [link] [comments]

How many fundamental particles are there? Posted: 17 Aug 2021 08:30 PM PDT It doesn't look like this has been asked before, and it seems like a simple question, but this article says there are 57 fundamental particles, this article says there are 36 fundamental particles, this article says there are 31 fundamental particles, and this article says there are 12 fundamental particles. So how many fundamental particles are there and what gives with the descrepencies between each of these articles? Have some fundamental particles not really been observed / proven, but are only suspected to exist? submitted by /u/Imminent_Extinction [link] [comments]

Can volcanoes form from 2 colliding continental plates? Posted: 17 Aug 2021 11:29 PM PDT In my very limited understanding, you need an oceanic and a continental plate for volcanoes to form? Or am I wrong? submitted by /u/Meowthful127 [link] [comments]

Why do photons always move at the same speed? Posted: 18 Aug 2021 05:23 AM PDT Not much more to it, this question just popped into my head. I don't remember learning the why of photons only moving at the speed of light, no more, no less. submitted by /u/Notagunner96 [link] [comments]

How do you track the orbital track of a satellite over another planet without a ground station? Posted: 18 Aug 2021 05:14 AM PDT With Earth orbiting satellites we have ground stations, but what about a satellite orbiting Mars for instance, are we able to tell the position of the satellite in relation to surface coordinates on another planet? submitted by /u/AuContraireRodders [link] [comments]

What proportion of transretinal is regenerated into 11-cis-retinol? Posted: 18 Aug 2021 04:39 AM PDT It can't be 100%, or else there would never be any need to add additional retinol into the system through the diet. Do we know how much it is? Google and the usual scholarly sources are coming up blank for me. submitted by /u/jamesbeil [link] [comments]

Have there been any recent studies or information regarding COVID and its infection rate in smokers? Posted: 17 Aug 2021 02:34 PM PDT I remember early on in the pandemic through to April and May of 2020, there was speculation that smokers were under-represented as COVID patients with significant infections, some calling it a "smoker's paradox". Has there been any more information regarding this idea? submitted by /u/tots4scott [link] [comments]

How can power have an imaginary component? Posted: 17 Aug 2021 09:51 PM PDT Okay, I did mechanical engineering for a few years undergrad, and I recall for a motors course we were taught power triangle. Power can have real and imaginary components, but how can something that's imaginary exist in the physical world? Is it something that we can harness? Is there any intuitive understanding to this? I sometimes plug in my phone charger and think there's so much happening that I'm just overwhelmed lol. Would love an explanation about this, or resources to learn more! Find it very interesting :) Also yea, I guess I should've paid more attention in class.... submitted by /u/willie_wonkerson [link] [comments]

AskScience AMA Series: Hey Reddit! We are NASA scientists that study Earth systems, how they're changing, and how they impact our favorite foods. Ask us anything about agriculture, drought, and food security! Posted: 17 Aug 2021 04:00 AM PDT When you think of NASA, you might think of rockets and space exploration, but did you know we play a big role in the food you eat? From space, Earth satellites have a unique view of fishing, ranching and farming our favorite foods, fruits, veggies, and grains! NASA data helps farmers and local communities address issues like water management, crop-type identification, land use, and sustainable farming processes. As the climate continues to warm, drought preparedness and food security continue to be challenges that NASA data helps overcome. We're here from 4pm - 5pm ET (16-17 UT) to answer your questions about agriculture, drought, food security, and NASA data. Ask us anything!

How did the jawless vertebrate immune system evolve? Posted: 17 Aug 2021 07:16 AM PDT "Jawless vertebrates do not have immunoglobulins (Igs), the key proteins to B-cells and T-cells. However, they do possess a system of leucine-rich repeat (LRR) proteins that make up variable lymphocyte receptors (VLRs). This system can produce roughly the same number of potential receptors that the Ig-based system found in jawed vertebrates can.[4] Instead of recombination-activating genes (RAGs), genes coding for VLRs can be altered by a family of cytidine deaminases known as APOBEC, possibly through gene conversion.[5] Cytidine deaminase 1 is associated with the assembly of VLRA and VLRC and cytidine deaminase 2 appears to assemble VLRB.[1][3]" This is from wikipedia. I wonder, how did VLRs evolve and how did cystidine deaminases evolve to affect the VLR genes in the right way? submitted by /u/ChardCommercial7579 [link] [comments]

How is addiction and dependence differentiated? Posted: 16 Aug 2021 08:48 PM PDT Can two people take part in substance use, both using the same drug, same amount and same schedule of use suffer from different psychological associations with that substance ? Can one be classed as addicted and the other only be classed as having a dependence ? Could someone else use the same substance than these other two and use it more regularly and not have an addiction to the substance or even a dependence ? How are addiction and or dependence determined? submitted by /u/ieatmushrooms7 [link] [comments]

How exactly does training for muscle hypertrophy work? Why do muscles grow the best at a certain intensity and certain volume? Posted: 16 Aug 2021 10:36 AM PDT The general rule of training for hypertrophy - as opposed to training for strength - is something like 70% your maximum, 10 repetitions per set. Those are generalized numbers, I'm not being accurate and this is broscience, but the core advice given is "less intensity and more repetitions will increase the size of your muscles instead of the strength." Alot of sites explain how but not why the muscles respond that way. Why at that amount and duration? submitted by /u/Ergheis [link] [comments]

How are electrons replenished when an element gives off electrons? Posted: 16 Aug 2021 04:57 PM PDT My understanding is that, as an example, the piezoelectric effect causes a crystal to shed electrons in the form of electricity if pressure is applied. If a crystal was to move electrons where do they move to, can the element or compound be stable for an infinite time? I know chemical bonding will directly move electrons between or among atoms. Silicone and gallium arsenide will shed electrons when struck by photons (I think). Does the photon replace the elections lost? submitted by /u/scuzzo500 [link] [comments]

In the 40s the US worked to eradicate malaria in the South through spraying of pesticides (like DDT), draining wetlands, and using things like mosquito nets. But mosquitoes (including ones of species that transmit malaria) still exist in the South. How was just the disease eradicated? Posted: 16 Aug 2021 01:22 PM PDT I suppose this may count as a history question so maybe this isn't the right place. But I am confused as to how mosquitoes, including the "common malaria mosquito", can still exist in the South but somehow the disease transmitted through the mosquitoes was eradicated. During the period of eradication did they just have a time where they had somehow just killed all the mosquitoes and so all the ones that could've had malaria were dead but then non malaria carrying ones of the same species just came back? The stuff I've looked up explaining the process just kind of go "we used DDT, draining stagnant water, and nets to get rid of malaria) but I don't see how that gets rid of malaria and not mosquitoes (which it obviously didn't). submitted by /u/KnightCyber [link] [comments]

I know someone who works with a Mass Spectrometer and LCMS. They seem to have lots of fine-tuning issues on picking up the proper measurements because (I think) is so much larger than what you are actually trying to measure.

What do the studies indicate about covid-19 vaccines effects on fetus and babies? Posted: 17 Aug 2021 02:17 AM PDT The official position in my country (not US) is that the covid-19 vaccine is "not contraindicated" during pregnancy.

Do plants like sundews(drosera), which grow worldwide, come from the same original plant? Or did they all independently adapt and mutate in a similar fashion?

When a vaccinated person is infected with a strain of a virus different from the one they were vaccinated against, do they create different anitbodies? Posted: 16 Aug 2021 03:36 PM PDT So with Covid-19, the vaccines are made with the original strain, so are antibodies work against the original strain. But when a vaccinated person gets infected with the Delta variant, in addition to making the OG antibodies, will the immune system also make antibodies specific to the Delta variant? Or will it just produce the OG antibodies? And to a further extent, if we made a vaccine against the Delta variant specifically, would it help at all with already vaccinated people or will it just reinforce the main strain antibodies? submitted by /u/gregfess [link] [comments]

How can people catch diseases from animals which are not subsequently transmitted from person to person? Posted: 16 Aug 2021 03:35 AM PDT I've just started reading The Plague Year: America in the Time of Covid by Lawrence Wright. In the prologue, he writes: People also get infections from animals, but they are not considered human diseases unless they are shown to be transmitted from one person to another. My reading (which may well be wrong) is that animal diseases may occasionally be transmitted from animal to human, but such transmission does not necessarily indicate that the disease will then be transmitted from that human to another human. But I'm struggling to wrap my head around this. Surely the limiting factor in disease transmission is the susceptibility to infection of the recipient - and so, once a pathogen has demonstrated that it can cross the species barrier and infect a human, that means humans are susceptible and human-to-human transmission is possible? If not, what is it that means animal-to-human transmission of that disease is possible but not human-to-human?

Posted: 15 Aug 2021 07:01 PM PDT The initial question came to me specifically regarding freestyle rappers, who can have marvelous adaptions of language. I am curious now if politicians, comedians, speakers, singers, etc may have enhanced or differential development of the speech/language center of the brain. submitted by /u/onlysoftcore [link] [comments]

Do we expect that "unsolvable" differential equations would have an analytical solution if we simply knew more math? Posted: 15 Aug 2021 05:38 PM PDT In my engineering studies and while reading the book Chaos, I see a lot of mentions of complicated differential equations without solutions. For example, the equation (dx/dt)+sin(x(t))=sin(wt) does not have an analytical solution as far as I know. Is there hope that if we had more functions at our disposal (for example, more functions like sine, hyperbolic sine, etc.) we would be able to find such a solution? Or is something like this fundamentally unsolvable for some reason? If it would be possible, are mathematicians working to discover these new mathematical terms? It fascinates me that we don't have the math to cleanly describe the three-body problem, for example, and it's hard to imagine that a clean solution wouldn't exist if we simply knew more. submitted by /u/JewshyJ [link] [comments]

What sorts of pathogens can we make vaccines against? Is it virus only? How far along are we from fungi vaccines? Posted: 15 Aug 2021 02:08 PM PDT submitted by /u/throwa_rock [link] [comments]

How did we categorize plants before we had access to DNA test? Posted: 15 Aug 2021 12:58 PM PDT I ask because there is a beautiful flower in my yard that is a type of onion even though it looks nothing like an onion. How could scientists tell what different looking plants were closely related? submitted by /u/Koalaesq [link] [comments]

Would it be possible to take a vaccine anywhere else besides in your skin and would it work? Posted: 16 Aug 2021 01:42 AM PDT submitted by /u/Lilyflower051 [link] [comments]

Can someone pinpoint me the exact location of the source of the Nile river? Posted: 16 Aug 2021 04:57 AM PDT The questions is not just about the Nile river, but any river, like the Amazon river, for example. What exactly is a source of a river? Why don't we see pictures of one? "The source of river X is hard to find" I've heard this many times and it makes no sense to me. There maybe multiple sources of a river and that's fine, but not being able to exactly pinpoint all of them is kind of silly in my opinion. What would happen if I were to walk a riverside backwards? I would definitely reach somewhere, where there's no river anymore, right? So, that's the source! (or a source, in case of multiple) Not to mention the ability to use satellite images. Searching for "Source of Nile river" literally yields to no useful results, just a few maps and some other random river pictures! I'm so confused. I would really love to see how a river starts or even visit it. submitted by /u/Outlaw_07 [link] [comments]

Do OTC expectorants like Mucinex offer any long term benefit for “clearing” symptoms permanently? Or do they just mask symptoms temporarily, and it’s better to let your immune system do the work itself? Posted: 15 Aug 2021 09:38 AM PDT This is always something I have been curious about. Some people seem to believe these medicines can be curative vs. just a temporary masking of symptoms, so I wasn't sure what was true. Thanks everyone! submitted by /u/jasminesunbear [link] [comments]

How does blackhole attraction at the same relitive distance away but different size blackhole work? Posted: 16 Aug 2021 02:28 AM PDT If I had a large blackhole and stood 5 radiuses away from it, then got a blackhole the size of my thumb and stood 5 of its radiuses away from it. Would the attractions be equivalent or not connect at all? (Assuming that there is no spin and charge and the blockholes are scale models of each other) submitted by /u/BrainSlug03 [link] [comments]

Was there less actual land mass when the continents were all pushed together or has it fluctuated over time? If it has, does that mean when the land mass was smaller, were the oceans on average not as deep? Posted: 15 Aug 2021 08:43 PM PDT submitted by /u/Tehbeardling [link] [comments]

Does the liver recover 100% from a live liver donation/transplant? Posted: 15 Aug 2021 08:06 AM PDT When a donor gives part of their liver for a transplant, does the donors liver recover 100%, or is there some damage/scarring that carries over from the surgery? Can complications arise later in life due to being a donor? Secondarily, does the donated liver become a 100% functional healthy liver in the person getting the transplant? Or is it life saving but not as good as having their original liver (if it was healthy)? I've been having trouble finding the specific information. I know both livers are expected to "recover and regenerate", and I know the transplati's body has to accept the new liver, but I've been having trouble finding if the livers are considered "100%" once healed, or if long term side effects are expected (however minor) submitted by /u/DwayneTheRockJson [link] [comments]

Could the use of Aducanumab in pre-symptomatic Alzheimer's patients halt progression of the disease? Posted: 15 Aug 2021 07:50 AM PDT While lots of medications for Alzheimer's focus on stopping the breakdown of acetylcholine, Aducanumab is directed towards "attacking" the amyloid plaques. Does this mean that an early diagnosis, at a stage when plaque formation is starting to occur but not to a high enough level to affect ones cognitive abilities (pre-symptomatic stage), could potentially result in a halting of the condition?

In oxygen concentrators, how do the zeolites (e.g. zeolite 13X) selectively bind N2 and not O2? Posted: 15 Aug 2021 04:52 AM PDT Apparently N2 binds via pi-interactions with the cations in zeolites? But why doesn't O2 do the same? Is the size difference of O2 and N2 relevant? And why is O2 smaller than N2, even though N2 is a triple bond and therefore much shorter in bond length?? submitted by /u/cowhead [link] [comments]

What is the science behind asymptomatic people with covid-19? Posted: 15 Aug 2021 01:44 PM PDT I mean, if you don't have symptoms, then you don't have the virus right? I am confused, but never knew where to ask submitted by /u/No_Philosophy8805 [link] [comments]
