| Why is 20:20 the standard for perfect vision? Posted: 23 Sep 2019 11:26 PM PDT Even when I'm wearing glasses right after going to the eye doctor, there are people with better vision than me. Why do glasses only bump me up to 20:20 vision when its possible for humans to see better than 20:20? [link] [comments]  |
| What is a rash at cellular level? Posted: 24 Sep 2019 02:00 AM PDT What is it that actually changes the skin colour? Why are there different types and patterns of rash? Why is it sometimes affecting only a particular area and other times the whole body? [link] [comments]  |

| How do they measure what happens when hadrons collide in the Large Hadron Collider? Posted: 24 Sep 2019 01:08 AM PDT I understand there are some different measurement systems such as Atlas Experiment. I have not understood how this actually manages to measure anything, e.g. 'direction and degree of curvature' of some particles. On YouTube and Wikipedia it specifies what is measured, but not how.

| Why Descendants of those who survived the plague in europe are immune to HIV? Posted: 24 Sep 2019 02:01 AM PDT I just read this somewere and i am a medical student so i just wanted to know the reason [link] [comments]  |
| Why can't a fighter jet reach orbit? Posted: 24 Sep 2019 03:07 AM PDT Hey guys, I just had a discussion with a friend which began with the reasons for the failure of the Space Shuttle. In the process we asked ourselves why you can't just fly straight upwards with a fighter jet to reach orbit which would cost much less than a rocket launch. We thought that maybe it is because the jets kinetic force is too low to reach the first cosmic speed so we compared it to a falcon 9:
So they both have around the same force per kg - shouldn't a Eurofighter then be able to just fly to space (maybe with some extra tanks)? Maybe there is a obvious reason why this can't work so thank you for your answers :) [link] [comments]  |
| Posted: 24 Sep 2019 02:38 AM PDT So, a two part question really that I came across while reading a bit of an old article: https://pdfs.semanticscholar.org/77ec/de583e04f0d3a112eeabd458d5dbcc05d6b1.pdf This mentions that heat shock proteins (HSPs) "aid in refolding of damaged or denatured proteins," but it does not discuss the mechanism by which this is accomplished other than stating that it increases the fidelity of protein synthesis. Wikipedia seems to just state that it stabilizes partially unfolded proteins, and chaperones other proteins, as I read it across organelle membranes. I am curious of the mechanism, is it attaching to other proteins like a ribosome or enzyme? Also, can HSPs be used to help treat prion diseases as they are a result of misfolded proteins? I see an article in 2014 discussing this potential, and also one this year showing mice lacking genes encoding for HSP synthesis have accelerated prion disease progression. I don't see anything further suggesting advances in trying to use HSPs for prevention or treatment of prion diseases, and maybe I'm just missing a piece of the puzzle. I'm just curious about HSPs and their potential. I'm in a pathophysiology course and this article is suggested reading but I don't have to do any homework related to it so I'm not asking for homework help, just trying to answer some questions that came up when reading. Thanks. [link] [comments]  |

| How do we know when quantum computers are correct? Posted: 23 Sep 2019 08:29 AM PDT How do we know that the Google Sycamore processor actually achieved quantum supremacy if we have no way of checking the results to see if they are correct, given that the same calculation it solved would take 10,000 years to run on the most powerful commercially available supercomputers we have now?

| Can a star in a solar system orbit another star? Posted: 23 Sep 2019 01:13 PM PDT So I'm making a world for D&D and I want it to include multiple suns but unfortunately I know nothing about astronomy. If a solar system is orbiting a sun, is it possible for one of the bodies in its orbit to be another star? If so then how would that affect the light or the heat on the planet (Like would the planet be in constant daytime, or would it be unusually hot?) Thanks for any help! [link] [comments]  |
| Does skin interact with itself between distant parts of the body? Posted: 23 Sep 2019 04:30 PM PDT In the same way an organ like the lungs function as one unit, can the skin on your legs communicate with or assist the skin on your head? For example, will the skin on your knee react to a pinprick on the skin on your shoulder? [link] [comments]  |
| How do brain regions actually communicate together? Posted: 23 Sep 2019 11:21 AM PDT This seems like it has a pretty obvious answer, but I couldn't really truly find any information on it without making my own guesses. To be clear, I mean 2 things by 'communicate'. How does the above vary with the split between the left side of the brain and right side of the brain? A particular reason for asking this is because we can for example verbally communicate and do a visualization task with a lot less interference simultaneously. [link] [comments]  |
| Why haven't Saturn's rings coalesced to form a moon? Posted: 23 Sep 2019 06:48 PM PDT If i'm not mistake its the remnants of a moon, but why has it spread out instead of lumping together over a long period of time? [link] [comments]  |
| Posted: 23 Sep 2019 09:13 AM PDT It's well know that adult teeth develop different for vegetarians and meat eaters, I was just wondering what else changes. Do former vegetarians break down protein more slowly? [link] [comments]  |
| How do we know that the Milky Way is a spiral galaxy? Posted: 23 Sep 2019 04:14 AM PDT Everywhere I read, it states that the Milky Way is a spiral galaxy. I never understood this since we can't (yet) see our own galaxy from an outside perspective. So my question is, how did we conclude that the galaxy we live in, is a spiral galaxy?
