| 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. [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)?

| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 18 Aug 2021 07:00 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [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 [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? [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? [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?

| 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) [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? [link] [comments]  |
| What are the primers for SARS-CoV-2 PCR testing? Posted: 18 Aug 2021 06:49 AM PDT |
| 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? [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? [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. [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? [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. [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? [link] [comments]  |
| Why is there a burning sensation after a tissue injury? (eg: sprained wrist, etc) Posted: 18 Aug 2021 03:53 AM PDT Why is there a burning sensation after a tissue injury? (eg: sprained wrist, etc) [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.... [link] [comments]  |
