| AskScience AMA Series: Updates on COVID vaccines. AUA! Posted: 04 Feb 2021 06:00 AM PST Millions of people have now been vaccinated against SARS-COV-2 and new vaccine candidates are being approved by countries around the world. Yet infection numbers and deaths continue rising worldwide, and new strains of the virus are emerging. With barely a year's worth of clinical data on protections offered by the current batch of vaccines, numerous questions remain as to just how effective these different vaccines will be in ending this pandemic. Join us today at 2 PM ET for a discussion with vaccine and immunology experts, organized by the American Society for Microbiology (ASM). We'll answer questions on how the current COVID vaccines work (and what the differences are between the different vaccines), what sort of protection the vaccine(s) offer against current, emerging and future strains of the virus, and how the various vaccine platforms used to develop the COVID vaccines can be used to fight against future diseases. Ask us anything! With us today are:

| How do antibodies attack coronavirus in the upper respiratory system? Posted: 04 Feb 2021 05:28 AM PST Every simple explanation I've ever heard about how antibodies work, describes an example where the virus is "floating around in fluid" like either blood or some other kind of fluid, and the antibodies float around too and "stick" to the antigens and neutralize the virus. But from my understanding, SARS-CoV-2 attack vector is the upper respiratory system, where it enters our body from floating droplets in our airways through the nose and mouth. The droplets then settle on the tissue inside of our airways and the infection begins there. Is my visualization of how that works correct? If such is the case, the virus is initially hitting "exterior" cells, because it is touching the cells that line your airway, so they are hitting a "wall" of cells in your nose and throat and beyond that wall is just a cavity filled with air. So how do the antibodies neutralize the virus in this situation? If the virus is not "inside" our body floating around in our blood stream. I'm curious to know the mechanics of this or if I'm just totally wrong about how all of this works. Thanks! [link] [comments]  |
| Why is so much of the American West dominated by coniferous forests? Posted: 03 Feb 2021 04:41 PM PST It seems like the West has a much higher proportion of conifers than forests east of the Great Plains do. Is this only because of generally higher levels of elevation and aridity? [link] [comments]  |
| Where in the US does the most weathering occur? Posted: 03 Feb 2021 06:50 PM PST I read that the most weathering occurs in warm wet environments so does that mean the most weathering is in Florida? I assumed it would be somewhere with mountains. [link] [comments]  |

| Does Photon Redshift (and blueshift) violate conservation of Energy? Posted: 03 Feb 2021 12:27 PM PST So, according to the laws of physics, energy cannot be created or destroyed, meaning the amount of energy stays constant, however, Photon redshift has the photon losing energy, but wouldn't that violate energy conservation? Because what exactly would the photon be losing energy to? If there's nothing for the energy to be transfered to, the only way for the photon to lose energy would be to destroy energy, which according to the laws of physics, isn't allowed, but since the photon is losing energy and it's not being transfer, is energy being destroyed as the photon redshifts?

| How do muscles store Glucose ? Posted: 03 Feb 2021 01:14 PM PST So as we studied, the liver regulates the amount of glucose in the blood , if the blood has 2.5g/l of glucose before entering the liver it'll come out with 1g/l , so how do muscles store glucose too? I mean, i understand they need it but if it's regulated when it comes out of the liver how can they store more of it. Please excuse me as English isn't my first language so i couldn't explain well my inquiry. Nevertheless, i hope you underatand and am awaiting your answer . Thank you. [link] [comments]  |
