| 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? [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? What does high pressure do to it? What will 10 atmospheres do it? 100 atmospheres? How about very low pressure? Anything? What happens to it when we apply electrical current through it? Low current? High current? How does it behave when we apply force to it? 10 Newtons? 100 Newtons? Etc. Is there a way to grow human tissue samples and infect it with Covid-19 to study it? [link] [comments]  |
| 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? [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. [link] [comments]  |
| Will related viruses compete with one another in a singular host? Posted: 18 Jul 2020 08:20 PM PDT Let's say I contract two different strains of the flu at the same time, will one eventually outcompete the other for available cells, or will I just have double the flu? [link] [comments]  |
| 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?

| 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? [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? I think this would be a good way to actually see how well we're doing vs status quo. [link] [comments]  |
| Can plants have too much water? Posted: 18 Jul 2020 02:18 PM PDT In the same way that a human's cells will explode with if they have too much water, can a plant have too much water? [link] [comments]  |
| 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? [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:
