| Posted: 11 Mar 2021 06:00 AM PST Is there a connection between what you eat and how you feel? A large body of research has demonstrated a strong association between the gut microbiome and mental health. Microbes have been associated with neurological disorders ranging from degenerative diseases (such as Alzheimer's, Parkinson's, ALS and dementia) to mental health disorders (like depression and anxiety) that are becoming all-too-prevalent in today's society. However, there is still much that we don't understand about how these relationships are established or maintained. Join us today at 2 PM ET (19 UT) for a discussion with experts on what is being called the "psychobiome", organized by the American Society for Microbiology (ASM). We'll discuss what we know about the relationships between microbes and hosts, how these relationships impact our behavior, moods and mental capacity, and what each of us can do to strengthen the health of our microbiomes, and, ultimately, improve our mental health. With us today are:

| Posted: 10 Mar 2021 01:44 PM PST Edit: I apologize to this community for asking such a foolish question, and potentially "wasting everyone's time." I obviously know the moon is tidally locked, but I know very little about planet science and wasn't sure of how rare or common the phenomenon is. I suppose I'll do more research before coming to this sub and asking such a basic question. To those that did help and were so polite in doing so, thank you immensely, you've given me a lot to go off of. I'm trying to come up with interesting settings for a fantasy/sci-fi novel, and this idea came to me. If its possible, what would the atmosphere and living conditions be like for such a planet? I've done a bit of googling to see what people have to say about this topic, but most of what I've read seems to be a lot of mixed opinions and guessing. Any insight would be great to have!

| How does a black hole consume matter? Posted: 10 Mar 2021 07:53 PM PST I watched the documentary Black Hole Apocalypse. Great show! Mind blown trying to comprehend super massive black holes. Host Janna Levin is describing how as you fall into a black hole time would slow to a crawl.( As seen by an outside observer). Neil DeGrasse Tyson then chimes in and says that you would literally watch the entire future of the universe pass before you. If time slows for matter approaching a black hole then how does anything ever get "consumed"? Shouldn't there be a traffic jam of cosmic proportions around the accretion disc, of matter waiting for billions of years to pass before it falls in? [link] [comments]  |
| Posted: 11 Mar 2021 04:06 AM PST I apologize if this question has already been asked, i could not find any threads or concrete answers about this (or maybe i just didn't understand them :). So, i've been reading about the mechanism of the new Adenoviral vector vaccines (AZ, J&J, etc). From all explanations i've read, this is my (very simplistic) understanding:
What i'm wondering is, basically, what exactly happens with the cell after that: Does the viral DNA degrade at some point? Once this DNA is in the cell's nucleus, for how long is step 3 executed? Since those vaccines are administered in the muscle, i'm guessing it's exactly the muscle cells that get 'infected' and start expressing the spike protein. And from a very quick search, it seems that the lifetime of a muscle cell is 10-15 years. I guess a bonus question would be, once the cell expresses the spike protein, does the immune system kill it or persistently continues trying to? In both cases, it doesn't seem like a great deal for a cell that's supposed to live that long :) [link] [comments]  |
| Posted: 10 Mar 2021 09:46 PM PST Specifically would like to know about the covid vaccine but also if there's a general tendency across the board. [link] [comments]  |

| How does gluons carrying charge influence the properties of the strong force? Posted: 11 Mar 2021 07:14 AM PST I have heard the reason why the strong force is unlike electromagnetism despite both having massless carriers is because the gluon of the strong force carries charge itself, meaning gluons can interact with each other. But what exactly happens when two or more gluons interact with one another that it makes the strong force so different from the electromagnetic? [link] [comments]  |
| When doing a pull up, is the bar exposed to more force when pulling up compared to hanging? Posted: 10 Mar 2021 11:59 PM PST I imagine that there would somehow be more force on the bar when pulling up even though the weight attached to the bar stays the same? I would love to hear an explanation as to why it is equal or more. [link] [comments]  |
| How can I improve the colour of a liquid solution? Posted: 11 Mar 2021 02:39 AM PST Good morning, This is the first time I've posted something on Reddit, and I'm curious to see what happens! I am working on a project to make fertiliser from plant waste through crushing, composting and other biological processes. I'm left with a dark brown/ black liquid that doesnt look very attractive! Could anyone give me some ideas about industrial processes which are used to change the colour of a solution to make it look more attractive. Many thanks, Alex [link] [comments]  |
| How long does a "toilet plume" last? Posted: 10 Mar 2021 03:51 PM PST I heard about this recently and i was wondering how long before the air in my bathroom (and the surrounding hallway) aren't contimated with fecal matter anymore and i don't care if its technically not harmful, i am disgusted by the thought of breathing in any of that air at all.

| How does a computer know whether a number is negative or not? Posted: 10 Mar 2021 02:26 PM PST Since a computer subtracts by adding the two's complement of a number to another, how would it know if the output is negative? For example, 2-3 in a 4-bit system is 0010 + 1101 = 1111 1111 converts to -1, but it also converts to 15, so how would it know the difference, because when you ask a computer to perform 2-3, it doesn't give -1 and 15, it only gives -1.

| Why is the weekly variation of COVID deaths in the US stronger than the variation of cases? Posted: 10 Mar 2021 08:30 AM PST Basing my question on the daily case and death graphs here: https://www.worldometers.info/coronavirus/country/us/ Both cases and deaths depend strongly on the day of the week, but cases fluctuate by about 20% around the rolling average, and deaths can fluctuate by over 100%. This seems backwards to me...people can decide when they get tested, when they see the doctor, when they go the hospital (to an extent) so I get why it's more common during the week. However, people don't choose when they die. Does this have some boring explanation like the fact that coroners don't work weekends? [link] [comments]  |
| Is it possible to make a radio-based “camera”? Posted: 11 Mar 2021 07:48 AM PST As I understand it, radio waves are just low-energy photons. Modern camera sensors are obviously designed to capture photons in the visible light spectrum, but a photon's a photon, right? What's stopping someone from making a "camera" that can capture radio waves to do things like looking through walls? [link] [comments]  |
| How are adult teeth moving in to place? Posted: 10 Mar 2021 10:30 PM PST I understand they are pushing into baby teeth and absorbing part of that root so the baby tooth will fall out but what is actually pushing the adult tooth? Is it a group of muscles? [link] [comments]  |
| Posted: 10 Mar 2021 09:48 PM PST Thinking about it, the only reason earthquakes are destructive to us now is because of the sheer amount of buildings we have built everywhere. There's also the tsunami afterwards but ancient people away from the coastline shouldn't have problems even with the strongest of earthquakes. Am I missing something here, or are they just not as big of a deal before than it is now? [link] [comments]  |

| Posted: 11 Mar 2021 01:00 AM PST Compare the charts of the daily cases of Israel to other countries especially the USA and Canada. The charts look almost the exact same. Why are the cases not decreasing with 43% fully vaccinated and 55% with at least one dose? [link] [comments]  |
| Posted: 10 Mar 2021 12:29 PM PST When you see "1000x as powerful as the bomb that dropped on Nagasaki", I implicitly assume it would cause 1000x as much damage. But surely that isn't the case? [link] [comments]  |
| What impact does alcohol consumption have on the efficacy of the new COVID-19 vaccines? Posted: 10 Mar 2021 03:30 PM PST Is there any hard data? Do immunologists have any kind of precedent here? [link] [comments]  |
| [electricity] Can we generate electricity by running wheels? Posted: 10 Mar 2021 10:47 PM PST Can we generate electricity by running wheels (such as car wheels). When the car move over the road, the flap deflects in downward direction due to the load exerted by the car. Converting the energy into reciprocating motion first and then converting this reciprocating motion into rotary motion. This rotary motion is used to generate the electricity ?? [link] [comments]  |
| Posted: 10 Mar 2021 01:17 PM PST News reports about covid vaccines claim a recent study found that moderna is about 12x less effective against the south african covid variant. They also claim the pfizer is 10x less effective. I was unable to find out exactly what that means by a typical google search. All the articles I saw repeated the 12x value, rather than breaking it down into numbers per 1000. Could some kind soul explain what they mean by this? [link] [comments]  |
