| What is happening physiologically when you have a “knot” in a muscle? Posted: 04 Feb 2022 10:30 AM PST What is happening physiologically when you have a "knot" in a muscle? By knot I am referring to a tight or particularly sore area in a muscle belly. When palpated it can feel like a small lump or tense area. They tend to go away with stretching, and or some pressure to the area. [link] [comments] |
| Why is the omicron wave *falling* so quickly in so many different political jurisdictions? Posted: 05 Feb 2022 07:53 AM PST For example: In NY (and several other US states), daily new cases has dropped by ~75% in the past 2 weeks. That seems much faster drops in new cases than previous waves. Why are case rates, after the peak of the wave happens, dropping so very quickly? [link] [comments] |
| Would plants still be green for photosynthesis if we had a different kind of star for our sun? Posted: 05 Feb 2022 07:21 AM PST Let's say we had a blue dwarf, neutrino, or red giant instead of Old Sol. Assuming we were still in a comparable habitable zone and life developed along similar lines, would our plants still be mainly green? [link] [comments] |
| The influence of Isaac Newtons spectrum at his time? Posted: 05 Feb 2022 08:43 AM PST Hello everyone, I wonder which influence Isaac Newton had with his discovery of the color spectrum and the invention of his color wheel at his time. I know that a lot of astrophysics today is done with spectralanalysis, but the spectralanalysis today is much more developed. Where did Newton had a direct influence with his color theory at his time? Who did use Newtons color wheel or spectrum so you could say Newton had a direct influence on him? [link] [comments] |
| Is it actually possible for a healthy individual to increase their lung capacity/function? Posted: 05 Feb 2022 03:05 AM PST When I was a kid I uses to think free divers and other swimmers could increase their lung size via breath training, but it turns out training actually just increases CO2 resistance. Still cool, but I'm still slightly disappointed these swimmers aren't actually growing their lungs like muscles. So, my question is, is it impossible for a healthy adult to increase their lung capacity/function? [link] [comments] |

| If a pregnant woman were to end up in a coma, would there still be childbirth? Posted: 04 Feb 2022 10:45 AM PST Say that the woman is now braindead and 8-9 months pregnant, would the child die in the womb or would there be sort of an "inactive" birth where the body takes control?

| Can someone explain the physical or chemical mechanics of cleaning carrot juice with vegetable oil? Posted: 05 Feb 2022 05:45 AM PST I washed for the first time carrot juice stain from a new white plastic kitchenware whit vegetal oil. It blew my mind how effective it was! Looked like a magic trick... [link] [comments] |
| Posted: 05 Feb 2022 04:55 AM PST It seems like so much happens between 0 and 200 degrees, and I just imagine that up in the thousands of degrees stuff doesn't change all that much. Is it just our confirmation bias since we obviously evolved to notice and care more about things that relate to us, especially organic compounds? (Is there a whole potential series of compounds analogous to hydrocarbons that have lots of things happen between 10,000 and 10,200 that we don't know about/there aren't conditions for in the universe?) Is it that more things happen between 0-200 at our pressure, but just as much would happen between 10,000 and 10,200 at, say, 0.01 atm? Or is it that the number of "interesting" changes is the same according to a geometric change in temperature, rather than arithmetic? So between 273K and 473K is almost double the energy, so maybe the correct comparison is 10,000K and ~17,000K? Or is the answer yes, just as much interesting stuff happens at any given band of 200 degrees? [link] [comments] |
| Lagrange plot: what is it really? Posted: 05 Feb 2022 03:28 AM PST There is a classic plot used to visualize or explain Lagrange points. Sometimes it uses isobars, sometimes it's 3d. You know the one. It's sometimes captioned as "potential energy". Sometimes people assume the gradient indicates the net force on a particle at that position. But what does this plot represent exactly? What is the value at an xy position? What is its unit? Is it scalar or vector? And why are the L4 and L5 points kidney-shaped "hilltops", implying a state of high energy? Aren't they supposed to be stable? [link] [comments] |

| Does albinism influence the body ability to synthesize Vitamin D from sunlight? Posted: 04 Feb 2022 06:46 AM PST Also, does an albino individual need around the same amount of Vitamin D as a non-albino individual? [link] [comments] |
| Posted: 04 Feb 2022 03:36 PM PST Hi r/askscience! Ive tried to do some personal research into the above question. Though I am aware that there are differences in the 'behaviour' of each individual species (D primarily affects cattle whereas A and B are infamous for seasonal epidemics in humans etc), I was just wondering what causes these differences in behaviour? Ive tried to find relevant papers, though most of those results focus exclusively on the subtypes of influenza A. I feel as though the answer might be obvious. If I were to hazard a guess, I would say that genetic variation has resulted in the evolution of four distinct strains (differing surface / spike proteins?), each with characteristic behaviour (host specificity, infectivity etc) differing one from the other. I might be completely wrong - but it was enjoyable to research. Any and all answers are greatly appreciated! [link] [comments] |
| How does heart transplantation work? Posted: 05 Feb 2022 01:46 AM PST Hi there, I am a high school senior studying for my med school exam and the materials sent by the university are about the cardiovascular system, more specifically the part about the anatomy and physiology of the heart, and about heart failure (pathophysiology, diagnosis, treatment options, education), from Kumar and Clarks Clinical Medicine 10th edition. I was reading about non-pharmacological treatments for HF, and they mention heart transplantation, but further down it says that heart allografts do not function normally because of denervation. At first I thought they meant that receiving a heart allograft means you have to take life-long immunosuppresant therapy for it to work, but then I realized that the denervation part cannot be solved by immunosuppresants. Right now I am at a loss to be honest, how does heart transplantation even work? Do the nerves reattach themselves in some case? Because I genuinely don't see how it would work. [link] [comments] |
| Posted: 04 Feb 2022 06:37 AM PST For example in the eye you can sometimes see very squiggly veins, but also in other places on the body. Would it not make more sense if all our veins were straight, meaning they're shorter and less work would be needed to pump the blood across the body? Or is there a reason for the squiggles?

| Why does chocolate keep its form until disturbed when being melted? Posted: 04 Feb 2022 07:51 AM PST So unlike most things (butter, candy, ice, etc..) that just turn into a puddle of liquid when melted, when I melt chocolate, usually on a double broiler, and refrain from constantly stirring it, the pieces of chocolate basically look the same but when touched by my spatula "spill" into their liquid form [link] [comments] |
| What’s up with the nerves in a horse’s hoof? Posted: 05 Feb 2022 03:36 AM PST Obviously there's a reason behind this: https://www.reddit.com/r/interestingasfuck/comments/sl1x7c/a_horses_foot_without_the_hoof/?utm_source=share&utm_medium=ios_app&utm_name=iossmf? Are they motor or sensory? I have so many questions, I don't know where to start. [link] [comments] |
