| Posted: 24 Dec 2021 08:13 AM PST Israel recently approved a fourth dose for the vulnerable citing waning immunity after the first boost. Peter Hotez endorsed a second boost for healthcare workers in the LA Times. This excerpt confuses me though: Article: https://archive.md/WCGDd
A few minutes googling didn't uncover anything. I'm concerned because I heard Osterholm mention (37:00) long covid may be the result of a compromised immune system. Could the fourth shot set the stage for reinfection and/or long term side effects? Or is it merely a wasted shot? [link] [comments] |

| Does toothpaste usage alter oral microbiome? Posted: 24 Dec 2021 06:05 PM PST I am unaware of papers that have tested the effect of brushing teeth with or without toothpaste on oral microbiome, but please let me know if there are any. I would hypothesize that the toothpaste would alter the microbiome compared to no toothpaste brushing, as toothpaste is inherently bactericidal and probably temporarily alters the pH of the mouth? There are papers that look into different types of toothpaste on oral microbiome, but I'm not sure how trustworthy they are. The million dollar question would be if using toothpaste alter the oral microbiome for better or worse? Edit: This paper is an interesting read on oral microbiome, does suggest the microbiome is important to tooth health, but still doesn't answer the questions at hand: https://www.nature.com/articles/sj.bdj.2018.81 [link] [comments] |

| Is it possible to catch Covid again immediately having recovered from it? Posted: 24 Dec 2021 04:39 AM PST Say you've completed your 10 day quarantine and recovered from Covid. If you were placed in a room with 5 infected people, would you get it again immediately? [link] [comments] |
| Posted: 24 Dec 2021 04:21 PM PST Given the large number of variations in Omicron, I'm curious if it likely came about gradually across a group of people with new variations occurring as it's passed to new hosts or all variations likely occurred within one person? [link] [comments] |

| Do at home covid tests test specifically for covid-19 or just any coronavirus? Posted: 23 Dec 2021 09:15 PM PST Hi everyone, A friend and I were talking about the at home test for covid 19 and we were wondering if the test are specific to covid-19 or all Coronas in general. We are not scientist and when we did a google search could find a quick answer on reputable sites(like cdc and such). Thank you!!! [link] [comments] |
| Why aren't agonic lines simply the line drawn from magnetic north to polar north? Posted: 23 Dec 2021 07:44 PM PST I was watching a video about magnetic declination and the presenter was describing how there are lines of zero declination (called agonic lines), where you don't need to adjust a compass at all for it to point to true north. That makes sense to me, but when I got curious and looked up NOAA maps that show magnetic declination lines I saw that the agonic lines weren't where I expected them to be, and furthermore they didn't even form straight lines when projected on a globe. Here's a picture of the current magnetic north (as of 2020). If you drew a line through the north pole and the magnetic north pole, and extended it around the globe, it would touch Eastern Russia, and also just west of Greenland. Now here is a map of current declination lines. The weird projection they used makes it hard to visualize on a globe but what's very clear is that there's a big ol agonic line shooting right through the middle of the USA, and that line touches neither the north pole nor magnetic north. There's also a second agonic line that does go from the north pole to magnetic north, except rather than just going straight there it meanders through Africa first! What the heck? Why is this? Wouldn't people in Manitoba have to adjust their compasses quite a bit to point true north? Because according to the map they don't. I don't know what concept I'm missing here but I'm hoping someone can help me out because this just makes no sense to me. [link] [comments] |

| How can we predict solar eclipses? And how were ancient people able to do so? Posted: 23 Dec 2021 11:12 AM PST Just something I've been wondering about for a while now... As I understand it (Thanks, Bill Nye!), the orbit of the moon is "wobbly" and somewhat random. Given that information, how can we accurately predict solar eclipses months, years, and even decades in advance? Additionally, how were ancient peoples able to predict them as well without advanced scientific equipment? [link] [comments] |
