| Do long-distance fibre optic cables ever make mistakes with the data they transmit? Posted: 11 Dec 2021 10:49 AM PST For example, could I send an email and the recipient views it with a misplaced letter because the fibre optic cable was damaged or just because something weird happened in transmission?

| Why is Dexamethasone used for severe covid patients if it has immunosuppressant effects? Posted: 11 Dec 2021 02:44 PM PST While I can see why you would want to take these steroids if you were experiencing cytokine storm, but most people who have covid, even if they need supplemental oxygen, aren't having cytokine storm. Is taking immunosuppressants while trying to fight off and infection counter-intuitive? Furthermore, dexamethasone inhibits gene expression of all three nitric oxide synthases. Isn't this also counter-intuitive? Not only does nitric oxide dilates the blood vessels, but it also works as an anti-inflammatory. Why would we want to purposefully lower nitric oxide levels if we are trying to recover from Covid? [link] [comments] |
| Posted: 11 Dec 2021 12:15 PM PST I just got my J&J booster today, and I got to thinking… The J&J vaccine uses a modified adenovirus to ultimately get into your cells and cause them to produce the covid spike protein (instead of more adenoviruses) so that you can develop antibodies to it. Makes sense. But wouldn't you also develop an immune response to the adenovirus itself? So if you get a second shot, how come your body doesn't end up destroying the adenovirus before they have a chance to get into your cells? Is it a case where it does, but not 100%, so it's still able to work? I guess another way of phrasing the question would be: how come they don't need to change the vector each time?
