| Are organs sensitive to touch? Posted: 19 Nov 2021 10:09 AM PST If I could somehow touch one of my organs, would I feel it? I can push on any muscle or organ and I only feel it on my skin. But at the same time, liver shots exist which seems to me that you they do feel pain. I'm guessing organs only cause you pain during acute trauma and not regular activities but I'm curious what the truth is. [link] [comments] |
| Do stars exist outside galaxies? Posted: 19 Nov 2021 01:58 PM PST I was watching this video and noticed how empty the space is between the galaxies so it made me wonder if it's possible for stars to exist in the seeming empty space of the universe. I'm not sure if stars are able to form outside galaxies, if it's not is there any known instance where a star has been seen outside a galaxy having formed within a galaxy and then drifted away from it to now be in the middle of nowhere [link] [comments] |

| Posted: 19 Nov 2021 08:29 PM PST I've always wondered about this. When you get a blood test of your total quantitative IgG / IgM / IgA the results are in mg/dL and they should fall within a certain range, also expressed in mg/dL. But when you go to get antibody measurements for a specific antigen (ex. SARS-CoV-2 spike) the results are usually in AU/mL (Arbitrary Units / mL) or BAU/mL (Binding Antibody Units), and these results are not comparable across tests of different brands. Why aren't specific antibodies also expressed in mg/dL? [link] [comments] |
| Posted: 19 Nov 2021 10:18 PM PST It's been demonstrated that PCR tests can still test positive for viral RNA days and sometimes weeks after the virus has been cleared from the body. The viral RNA isn't actually from viable virus, but the remains of destroyed virus.

| How much does vaccine injection site really matter? Posted: 19 Nov 2021 07:22 PM PST Aside from, for example, so long as a subcutaneous vaccine is administered subcutaneously, does it really matter where on the body? Does it impact level of effectiveness, whether it's effective at all, etc.? For context, I was looking into where on the body cats and dogs receive their shots and wondered how much it really mattered. [link] [comments] |
| Are there any specific instances of volcanic eruptions warming the climate? Posted: 19 Nov 2021 12:29 PM PST I'm familiar with the ways in which volcanic eruptions can have lasting cooling effects, such as Krakatoa, and even with the Paleocene-Eocene Thermal Maximum, which could have been triggered by volcanic eruptions causing the release of plant-based carbon into the atmosphere, thus having a warming effect. I know that the release of greenhouse gases by volcanoes is not the cause for the current climate change we are seeing. However, I am interested in knowing if there has been in the past a specific event in which a volcano or a series of volcanoes released enough greenhouse gases to cause a warming effect themselves.

| Do diseases that impact people with hypertension do so regardless of if the BP is controlled? Posted: 19 Nov 2021 05:57 AM PST I'm hypertensive but take medication and am trying to exercise to bring it down. Say I get to a level where, after losing weight and being on the meds for a while, my BP is in the normotensive range. Am I still as susceptible to diseases as I was when I was unmedicated and had high BP? [link] [comments] |
| Posted: 18 Nov 2021 11:00 PM PST My guess is that within minutes my temperature and nutrients would drop more than enough to kill basically everything but I don't know—thats why I'm asking! [link] [comments] |
| How much did taxonomy change with the advent of gene sequencing? Posted: 19 Nov 2021 07:02 AM PST Change the process going forward as well as change the existing classifications. Are there some examples of previously miscategorized species? [link] [comments] |
| What does it mean to drink yourself to death? Posted: 19 Nov 2021 08:09 AM PST Sorry in advance if this is the wrong sub. I was gonna put it in /r/AskDocs, but I felt like it wasn't quite the right place? Do correct me if I'm wrong. As for the question, I'm not talking about dying of alcohol poisoning or anything like that. Every now and then you hear about people who drank themselves to death, and it's always been super vague to me what exactly that means or entails. It sounds like it must be a gradual process, but if that's the case how does it kill someone before they get medical attention? As a person who has been drinking fairly heavily every day, without missing a single day for what I'd assume is close to a year, this is a question that crosses my mind every now and then.

| What does chlorophyll break down into when heated or comes in contact with HCl? Posted: 19 Nov 2021 07:44 AM PST Yesterday, i started a project where i want to extract magnesium metal from spinich leaves. I know chlorophyll contains a single magnesium atom per molecule, and my goal is to seprate it. Ive already done a test on seeing if my method of burning it to ashes and adding HCl to it will make MgCl2 and it seems to work. But i have no idea what else is created/left over in the process. So what is created when chlorophyll reacts with HCl (without burning) , and whats left after buring it (without the acid)? [link] [comments] |

| Posted: 19 Nov 2021 12:12 PM PST Is it a chemical reaction that causes heat and physically raises the temperature of your skin? Or does it make receptors think they are warm and produce that warm sensation? Or does it make blood rush to the area and make it feel warm? or something else entirely? [link] [comments] |

| Why does a group of particules act as a singular body in regards with gravity? Posted: 19 Nov 2021 10:13 AM PST We always explain gravity as if every object's gravity was singular and independent from another's gravity. For example, the moon and Earth have distinct gravities, but it's not because the moon is attracted by the Earth that Earth's gravity changes. My question is, if every particule with mass exerts gravity, how come every gravity of every particule of an object conglomerate to a single gravity for the object? [link] [comments] |
| Autorefractor - how does it measure eye focus? Posted: 19 Nov 2021 02:40 AM PST Even though I watched many videos and read articles about how an autorefractor works - I still haven't found how does it get the result. My understanding is:
How? It might be a silly question, but I am really wondering on how it gets the result. Are the waves reflected back from the eyeball to the machine? (I'd assume yes as I can't think about any other option) I'd be very great full for an idiot proof answer ;) [link] [comments] |

| Are stars actually in the direction we look at? Posted: 19 Nov 2021 12:25 AM PST In an experiment video, a guy talked about that during an eclipse, some researchers tried an experiment to try to look at a star next to the sun from the earth. They could but astronomers knew it wasn't there, it was behind the moon. The photons projected by the star were getting bent by the moon's gravitational pull. My theory, could all the stars we see from earth aren't actually meant to be seen? They're all getting bent by some gravitational pulls across our universe and ended up pointing in our direction?
