| Why is chickenpox more dangerous for adults? Posted: 25 Jun 2021 04:59 PM PDT Adults get more dangerous symptoms and are more likely to die because of chickenpox but why does it hit adults so much worse than children? Google couldn't tell the reason. It only told it is worse for adults but didn't tell why. [link] [comments]  |
| When someone is emotional and “choked up” or has a lump in their throat, what is actually happening? Posted: 25 Jun 2021 08:46 PM PDT Basically the title, sometimes when I'm really sad and crying, it's really hard for me to talk because my throat feels like it's closing up, what's the deal with that?

| Posted: 25 Jun 2021 09:22 PM PDT It seems that most people we meet now have some form of depression, anxiety, PTSD, obsessive-compulsive, etc. and the mental health crisis is (rightly) very often in the news (though admittedly that's not a conversation limited to how many cases there are but also treatment, social attitudes, funding, etc.) and it makes me curious if the scientific community regards this as a relatively new thing? To clarify, we're all aware that the history of mental health is an interesting and complicated one. From an issue with one's "humours" to the application of the word "melancholy" to mean anything from full-on psychosis to general unhappiness to "hysteria" and so on, there have been words that really didn't convey individual illness-symptoms. There's also "madness" and the argument of mental illness as a disease, a state, a phase, etc etc. The past didn't quite document symptoms and illnesses with as meticulous records as our own and we have far less documentation than we'd like about the epidemiology(?) of mental illness from the past I'm sure. Even Samuel Johnson is often-seen now as having obsessive-compulsive disorder but in Boswell's biography it's mentioned that he suffers from melancholy and has strange "gesticulations" but not connection is drawn between the two with the latter seemingly regarded as more of a character oddity. Does the poor categorisation and diagnosis(ses?) of mental illness in the past (or, flipping it I guess, the widening of terminology to include more things within the bounds of 'mental illness') largely contribute to why mental illness seems so common now or is there actually a genuine explosion of more mental illness occurring in recent years? EDIT: Also, I'd be curious about the self-reported vs. diagnosed conversation, too. [link] [comments]  |
| How they capture the galaxy's photo? Posted: 25 Jun 2021 02:40 PM PDT Can i ask? How is it possible to capture the galaxy's picture? If we are on this galaxy like milky way. How? You have to like fly a drone to capture something below from above, right? So how? [link] [comments]  |

| What would happen if you have (asymptomatic) corona at the time of your vaccination? Posted: 26 Jun 2021 02:21 AM PDT Would you get extra sick? Would it stop you from developing symptoms? I could not find an answer to this online. [link] [comments]  |
| Posted: 26 Jun 2021 08:11 AM PDT This article claims they've discovered a new species of human, which is awesome, but since the claim is based off a single fossil, how do we know that it wasn't just one person with some sort of genetic defect? [link] [comments]  |
| Does infection produce different kinds of antibodies than vaccination? Posted: 25 Jun 2021 12:57 PM PDT I know that for example Hepatitis B vaccination produces different antibodies than infection. This is because the vaccine does not contain certain structural components of the virus. Does something similar happen with SARS-CoV-2 as far as we know? [link] [comments]  |

| This might sound like a stupid question, but was the sky pitch black eons ago? Posted: 25 Jun 2021 01:47 PM PDT I'm new to this sub and I was curious, since I had nothing to answer this question with other than my own headcanon. So this might actually have a short answer than expected. So light takes a super long time to travel right? Since what we're seeing up there (outside of the solar system) are dead or dying stars and the info hasn't reached our eyes yet. So was there a time when no light from outside the solar system had reached the earth, making the sky pitch black at night save for the sun? [link] [comments]  |
| What affects buoyancy more, density or total mass? Posted: 25 Jun 2021 10:46 PM PDT So my thought is basically if you take a metal boat and you put a wooden crate inside of it that the boat would sink deeper in the water. I have no idea how all this works but that kind of just makes sense in my mind, yet I have to consider that an equivalent wooden boat would float much closer to the surface, obviously because wood is less dense than metal. So my question to you all, is what would happen? Would the boat rise in the water because the overall density of everything on it has lowered; Or would the boat sink because more weight has been added to it? [link] [comments]  |
| Covid testing for Tcells and memory cells? Posted: 25 Jun 2021 10:43 PM PDT I was reading some discussion about how the lack of detectable antibodies sometime after covid infection doesn't necessarily indicate a lack of immunity because we don't yet know the effectiveness and duration of the T-cells and memory cells acquired in the body after infection (and after vaccine?) Is there any current testing for Tcells and memory cells from Covid like the antibody testing? [link] [comments]  |

| How does rain come down diagonally with no wind? Posted: 25 Jun 2021 11:43 AM PDT I suspect it has a simple answer such as wind at higher elevations? I've Googled and searched Reddit and couldn't find a definite answer. [link] [comments]  |
| Quantum mechanical spin and rotation of the wavefunction Posted: 25 Jun 2021 07:52 PM PDT If you rotate a spin-1 particle by a full circle, you get back the original wavefunction. If you rotate a spin-½ particle by two full circles, you get back the original wavefunction (if you rotate it by one full circle, you get a factor of -1). If you rotate a spin-2 particle by half a circle, you get back the original wavefunction (I believe, and cannot find a proper reference) Does this pattern hold for higher half-integer spins? If you rotate a spin-3/2 particle by ⅔ of a full circle, do you get back the original wavefunction? If you rotate a spin-5/2 particle by 2/5 of a circle, do you get back the original wavefunction? If the answer is yes, do you have a maths reference? This isn't a homework question - I'm a very, very lapsed physicist and I've never quite seen the right maths or physical intuition to answer this question [link] [comments]  |
