If I would go into my vegetable garden and scoop up a tablespoon of soil, inspected it millimeter by millimeter under a 40x-100x microscope: which and how many visible-sized organisms (insects, arthropods, etc.) would I be able to find?

If I would go into my vegetable garden and scoop up a tablespoon of soil, inspected it millimeter by millimeter under a 40x-100x microscope: which and how many visible-sized organisms (insects, arthropods, etc.) would I be able to find? Posted: 01 Nov 2020 03:33 AM PST For context: my backyard is a vegetable garden in coastal Western Europe with dark brown dirt and grows mostly beans and gourds. I'm slightly interested in purchasing my own (cheap) microscope and just having a field day in my backyard, if that'd be viable. I've been looking at some Wikipedia pages and there's tonnes of pages that list tiny (0.1/0.2mm) insects and other critters whilst stating that they're commonly found in regular top soil everywhere. Some sources that I've found online list incredible numbers of arthropods, insects, nematodes, etc., with numbers up to millions per square feet. submitted by /u/Straight_Chip [link] [comments]

What makes a virus airborne? Some viruses like chickenpox, smallpox and measles don't need "droplets" like coronavirus does. Does it have something to do with the size or composition of the capsid? Posted: 31 Oct 2020 09:18 AM PDT In this comment: https://old.reddit.com/r/askscience/comments/fjhplb/what_makes_viruses_only_survive_in_water_droplets/fkqxhlu/ he says: Depending on the composition of the viral capsid, some viruses can be relatively more robust while others can never survive outside of blood. I'm curious if size is the only factor that makes a virus delicate. https://en.wikipedia.org/wiki/Capsid this article talks about capsomere and protomere, but doesn't talk about how tough it can be. Is there any short explanation about capsid thoughness, and how it related to virus survival? submitted by /u/jokoon [link] [comments]

What are the numbers of Influenza infections yearly? All I can find on the internet is death tool. Doing infographic about comparing Covid to Influenza, and infection rate is really important factor imo. Posted: 01 Nov 2020 03:54 AM PST People in my country love to compare influenza to a Covid. Most of them not realizing that Covid death tool is only so low cause of rules, while if the Covid been as common as influenza, numbers would be a lot worse (New York, Italy and frankly my Country) submitted by /u/LegendCZ [link] [comments]

What happens when I open the window in a warm room? Posted: 01 Nov 2020 03:38 AM PST When I open the window, cold air comes in and warm air leaves. But how does this happen? I vaguely imagine the the cold air comes in at the bottom of the opening and warm air leaves at the top. Are there vortices somewhere in the middle? If I could dye the air on the inside one colour and the air on the outside another colour would I see anything interesting when I open the window? submitted by /u/l_lecrup [link] [comments]

When a person donates a kidney, what is filled in that void left by the kidney? Posted: 01 Nov 2020 02:34 AM PST I know that a human can live with one kidney but when it is donated or removed because it's damaged, what is filled in the void? If nothing is filled, will other organs just move and occupy the space of this kidney? submitted by /u/jabhiram [link] [comments]

How does a hard disk create space for new files after deleting old ones but is still capable to recover those deleted files? Posted: 31 Oct 2020 07:34 PM PDT As soon as I empty my recycle bin my windows PC tells me, I got now more space to put new files in to. I can even limit out this space. Still with apps like Windows File Recovery I can see files which has been deleted months ago and recover like they were never gone. How is this possible? submitted by /u/bulwix [link] [comments]

When draining a double sink with unequal water volumes, why does the one with less water not drain until the other one has an equal volume? Posted: 31 Oct 2020 11:47 AM PDT This is a phenomenon that can be observed in your average kitchen sink at home or the office, provided the one with less water is directly over the t-pipe and both drains are unplugged simultaneously. It has never ceased to puzzle me since I first observed it. submitted by /u/SupersuMC [link] [comments]

When we drink, why does our urine turn clear? I thought alcohol was supposed to DEhydrate us? Posted: 31 Oct 2020 07:41 PM PDT So my intuition tells me that urine color is not the best indicator of how hydrated we are. So, what is it that makes our urine dark/clear and why are we always told it is an indicator of how hydrated we are? submitted by /u/Wzup [link] [comments]

Theoretically, if all currently living aquatic creatures were to suddenly disappear from the ocean, would it cause a significant change in the global sea level? If so, is it possible to estimate how drastic the change would be? Posted: 31 Oct 2020 07:02 PM PDT This is, of course, assuming no other dire consequences such a extreme change in equilibrium in the planet's ecosystem. submitted by /u/HailToTheThief225 [link] [comments]

How does relativity allow for this to be true? Posted: 31 Oct 2020 02:52 PM PDT If you are in a lab that is moving near the speed of light in the x direction and you shine two beams of light in the negative x direction and the positive x direction how would they travel at the same speed from the rest frame of the lab? From my intuition it seems that the beam traveling in the negative x direction should reach the other wall in about L/2c while the one in the positive x direction would take super long. How does time dilation change both of these to L/c when one is faster and one is slower? submitted by /u/walkerspider [link] [comments]

Clean Coal? Are there different types of coal that give off different emissions? Posted: 31 Oct 2020 11:13 AM PDT Listened to Joe Roegans interview with Tim Dillon and Alex Jones today.... One of many questions I have is the "clean coal" discussed, is it real? Namely is there a large deposit in America that burns much cleaner than other types of coal irrespective of coal fired plant technology used to "scrubb" Thanks submitted by /u/weshtlad [link] [comments]

What is actually happening when you get “BrainFreeze” after eating something cold? Posted: 31 Oct 2020 12:39 AM PDT Is it really your Brain you can feel and why is it so unpleasant? submitted by /u/CrapTaxidermy [link] [comments]
