| Posted: 28 Aug 2021 03:07 PM PDT Hi all, Aquarium enthusiast and 2x rabies shots recipient. I have lived dangerously so to speak, and lived! But I have a question for you all. I was at my local fish store joking with the owner who got gouged by one of his big fish (I think a cichlid). I made a joke about rabies and he panicked for a brief moment, until I told him it's common knowledge that fish don't get rabies. I was walking home (and feeling bad about stressing him out!) when I started to wonder why. For instance, the CDC says only mammals get rabies. But there's a case of fowl in India getting rabies. I saw a previous post on here that has to do with a particular receptor that means birds are pretty much asymptomatic and clear it if exposed. Birds have been able to get it injected in lab experiments over a hundred years ago. I also know rabies has adapted to be able to grow in cold-blooded vertebrates. So, what about fish? Why don't fish get it? Have there been attempts to inject fish in a lab and give them rabies? Or could they theoretically get it, but the water where they bite you essentially dissipates the virus? Or is there a mechanism (e.g. feline HIV —> humans) by which the disease can't jump to fish? Thanks for any insight. I will be watching Roger Corman's "Piranha" while I wait on your answers.

| What are the effects of vaccine mandates on vaccination rates? Posted: 28 Aug 2021 01:18 PM PDT In King County, WA USA there appears to be no effect as vaccination rates are relatively unchanged since the August 9th mandate announcement by the Governor and County Executive.

| Why does the Watermelon mosaic virus cause a ring/ripple pattern, skipping some tissue ? Posted: 28 Aug 2021 11:48 PM PDT It looks like it's spreading from a center point but skips some tissue and leaves gaps - what mechanism would cause this ? If it's just the spread of a virus shouldn't it be a continuous yellow spot ?

| Posted: 29 Aug 2021 07:05 AM PDT For the inactivated coronavirus vaccine. Pretty much the title. As in; if you have strong t cell immunity before vaccination would that cause the killer T cells to destroy the viral particles from the vaccine faster and more efficiently so there would be less antibodies produced?

| Posted: 28 Aug 2021 11:27 AM PDT I just really got into Botany and love it. I can't help but appreciate all the hard work that has gone, goes, and keeps going into taxonomy, and I think it's really neat/classy how if a plant was named by Linnaeus it just gets an "L." instead of a name (just a plant thing and not an animal thing which is even neater to me but I digress). I'm kind of interested in him and I'm interested if there were any plants that held significance to him for helping him with his naming conventions. Also maybe just wondering if he had some plants he really liked, even on a personal level. More generically if there are any good videos or guides about Carl. Sorry if this is more of a history question, but it seemed like the people who would be knowledgeable about this would be botany majors way more than history majors. [link] [comments]  |
| What is a good beaker specifically for use with laboratory hot plates? Posted: 28 Aug 2021 03:53 PM PDT Apologies if this barely skirts by the rules of posting, but I couldn't find a more relevant subreddit. I recently purchased a hot-plate, and it gets plenty hot, but it can't seem to properly heat my solutions. I've pretty much narrowed it down to my beakers having exceedingly poor surface-contact with the hot plate. Any suggestions on beakers with nice flat bottoms to avoid this issue? Water/oil baths are not practical. [link] [comments]  |
| Why do tectonic plates "float" on magma and not sink? Posted: 27 Aug 2021 10:46 PM PDT Every explanation of plate tectonics begins with the phrase "the plates float on a layer of magma". And generally speaking the solid form of a substance tends to be more dense. Therefore, shouldn't the tectonic plates sink, form a new cooled crust, then that would sink, etc...? I assume I am missing something fundamental here. Please educate me. Edit: I am trying to be polite about this, but the more I look into it, the less I find and the more I seem to get veiled mocking for even asking the question. If it's so damned simple, would someone please just explain it. Its not like I'm asking you to teach our nations children to read or unify Feynman's work with the new testament. [link] [comments]  |
| Does burning your rockets in retrograde really make you go faster while in orbit? Posted: 28 Aug 2021 04:46 PM PDT So, I posted this in today I learned, and have gotten nothing but pushback since posting it. Could some of you smart people weigh in on it? https://www.reddit.com/r/todayilearned/comments/pd4qb0/til_that_orbiting_the_earth_you_actually_move/?utm_source=share&utm_medium=mweb I saw it watching #veritassiumcontest videos, which are supposed to be counterintuitive. This is the video in question: https://youtu.be/kgFehXwKFMM Thanks smart people! [link] [comments]  |
