| How did the SARS 2002-2004 outbreak (SARS-CoV-1) end? Posted: 01 May 2020 02:29 PM PDT Sorry if this isn't the right place, couldn't find anything online when I searched it. [link] [comments]  |
| Why are antiviral medications so much less prevalent than antibacterial? Posted: 01 May 2020 12:55 PM PDT It seems like we have a lot of defenses against bacterial infections, and have had them for quite some time. I'm curious why it appears that anti-viral equivalents are so much less pervasive? And the ones we have, seem so much more dangerous than the antibacterial counterparts. [link] [comments]  |

| Can we use soap and water to clean everything instead of using disinfectant? Posted: 02 May 2020 12:28 AM PDT They have explained to us that we should wash our hands with soap and water because the soap rips apart the outer lipid / fatty layer of the virus and destroys it. So why do we need lysol, Clorox, multi purpose cleaners, alcohol, bleach etc. if soap and water are so effective at destroying the virus? I do understand that hand sanitizer is necessary for the times when we do not have access to running water BUT why can't we just clean our countertops, floors and other surfaces with just soap and water? Why can't we spray soapy water onto surfaces to destroy that outer lipid layer and destroy the virus then wipe it away? Thanks [link] [comments]  |
| How do surgical masks become ineffective? Posted: 02 May 2020 12:27 AM PDT I was told that surgical masks last shorter/becomes less effective if used in a hospital compare to say when you go out for groceries. But how does it become ineffective exactly? Does it get saturated like a cloth getting wet, or filters trapping dust? On a similar note, if the virus can only survive on surfaces for certain amount of time: If we leave a used mask/clothings untouched for that amount of time, does that make it safe to use again? If we can disinfect clothings and other surfaces, why can't masks be disinfected? [link] [comments]  |
| What makes outside air smell fresh? Posted: 02 May 2020 12:14 AM PDT What is it that makes the air from outside feel so refreshing when I let it mix with the "neutral" feeling air of my bedroom? Is there something in the air outside that somehow dissipates when it's enclosed somewhere for a while? Is something psychological going on? What's up with that good-feeling air? [link] [comments]  |
| Why do Saturn’s rings stay in rings? Posted: 02 May 2020 12:32 AM PDT As far as I know, the rings are made out of ice and just space debris I guess that are stuck in orbit around the planet (again as far as I know I'm guessing it would be similar to how our moon orbits us). But what makes them stay flat the way they are? If they're in orbit in the first place because of gravity, why aren't they pulled closer to the planet, in more of a spherical shell around it or something? [link] [comments]  |
| What is the most optimal shape for a glass to keep my beverage cold ? Posted: 01 May 2020 03:46 PM PDT I just took a cold beverage out of the fridge and I wondered what shape of glass would be perfect to keep the beverage cold the longest. Would a spherical glass have less surface to take heat from? Or would for example a high but small diameter cylindrical glass be better? Or would they behave the same? What would be the ideal ratio between beverage-to-glass and beverage-to-air surface size? (while still considering the glass to be drinkable from) [link] [comments]  |
| Is it possible that COVID-19 was endemic previously? Posted: 01 May 2020 12:37 PM PDT Over the past couple weeks, I've heard from several people that they're convinced they caught COVID-19 before this pandemic happened. For instance, my Mom visited Disneyland three months ago, and about ten days after she got back, she got sick with all the classic symptoms. (Dry cough, loss of taste and smell, fever, etc.) This is obviously a very small sample size, but as I've heard from more and more people that feel the same way, I began to wonder. Is it even remotely feasible that COVID-19 could have already spread across the world, and now that we've noticed it and are testing for it, we see the pandemic? It seems like a long shot and I know there's something wrong with my logic, but I can't put my finger on it. [link] [comments]  |
| Difficulties in mass producing antibodies? Posted: 02 May 2020 03:00 AM PDT Our pharmaceutical companies seem to have little problem synthesizing the molecules of their chemical drugs on a mass scale. Why is mass producing proteins and antibodies so much more difficult? We still have to use convalescent plasma from living donors to provide antibodies, and monoclonal antibodies don't seem to be produced on a mass scale. Is it because proteins like antibodies are many many times more massive and complex than the molecules synthesized in traditional drugs? [link] [comments]  |
| When steel decomposes completely does it turn back into carbon and iron? Posted: 01 May 2020 03:59 PM PDT My wife and I have been talking about composting and things decomposing. (Context - planning for our apocalypse farm and discussing the different ways to get rid of trash). If you bury steel in the ground, what would happen? How long would it take? [link] [comments]  |
| Posted: 01 May 2020 11:14 AM PDT So with everyone thinking about SARS-CoV-2, I will frame my question with examples related to this virus. I'll abbreviate SARS-CoV-2 to CV. The primary mechanism of infection by CV is uptake by the body's ACE2 receptors. My understanding of cellular receptors is that they are naturally specific and only interact with a very limited range of molecules, with the CV spike protein unfortunately being among them. However, there are plenty of other molecules that act with these ACE2 receptors, molecules produced by the body or some pharmacological body (only pun here!). Antibodies should be specific to target the virus and not much else, but specificity isn't absolute, as is with the cellular transport machinery. Do we know of cases where the antibodies produced in response an infection also have loose-specificity with other things in the body and can be deleterious? What would this look like? Would this be an environmental cause of certain autoimmune diseases or allergies? Given the use of ACE inhibitors for management of high blood pressure, could CV antibodies affect the utility of these drugs? I know plenty isn't known about CV, but figured it would be an appropriate example to describe my thinking about protein specificity, so I'm not looking for just CV responses. Thanks!

| How do villages and civilizations become buried? Posted: 01 May 2020 08:18 AM PDT Archeologists dig up bones, objects, even entire villages 10-20 feet underground. How did they get that far down? Where did all the dirt that is covering them come from? Why aren't we being buried? [link] [comments]  |
| Posted: 01 May 2020 11:55 PM PDT It's not for me it's for a book. The exact numbers I used were a temperature of 108.1 Fahrenheit and a heart rate of 143 over 92. Also, the character is a 10-year-old so should I adjust these numbers to make that more realistic? The doctors don't know what's wrong with him he was just brought into the ER after fainting. I don't know if that is realistic considering what is wrong with him (though the doctors don't know yet) is that he has a blood infection. Any help would be greatly appreciated. [link] [comments]  |

| What are the differences in new EUA approved Covid-19 rRT-PCR tests? Posted: 01 May 2020 04:52 PM PDT So I'm looking into all the new Covid-19 tests being approved for use under EUA and for all the rRT-PCR tests, other then some being multiplexed or being for a specific detecting machine I dont really aee any difference in the 40+ plus new tests. Is all that is differentiating them patented reagents for binding to the N, E, or ORF1ab Gene's of the virus? Has each one found a new way to bind to these Genes to detect them or is there some other difference I'm not understanding or seeing? Hope this question is ok for this sub! Thanks for any information! [link] [comments]  |
| What happens to the sperm when not masturbating? Posted: 01 May 2020 04:21 PM PDT ive heard of people not masturbating for a year, but what exactly happens with the sperm thats being produced, doesnt it "overflow" or "spill out" in some kinda way? Or do you after a long period without releasing semen just ejaculate at night during a wet dream or something else [link] [comments]  |
| How do the plants completely underwater make their food? Posted: 01 May 2020 08:41 AM PDT Where there is total darkness, and the plant is unable to carry out photosynthesis, how does it make its food? [link] [comments]  |
