Does HIV cancel out any allergies a person may have? Posted: 16 Dec 2019 05:26 PM PST From my (admittedly limited) understanding, HIV causes your immune system to fail nearly completely Allergies are an overreaction of your immune systems reacting to something that is not a threat to the body If you were allergic to cats as an example, contracted HIV, and somehow came into contact with a cat, would your body still react to it in similar ways? Edit: u/streeturchin1337 has said in a comment down there that they may have heard of leukemia and HIV essentially cancelling each other out in terms of white blood cell count. I too am interested in this so have popped it up here submitted by /u/mexicanpenguin-II [link] [comments]

How does a computer know how to do math? Posted: 16 Dec 2019 03:27 PM PST I've been searching for ages for an answer to this question, but I haven't gotten an answer. I know that a computer receives an instruction from memory, converts the instruction into numbers, then into binary 1s and 0s, and only does math as the base for everything, but how does it know every rule of math and how to solve math problems. After all, it's just a piece of silicon with semiconducting transistors that can hold or release current, all put together by wires known as clocks that make up the microarchitecture. How, how, does it know math? submitted by /u/quickmade-acc [link] [comments]

When a tree (or other land plant) is immersed in water, what does it die of? Posted: 16 Dec 2019 06:25 AM PST Let's pretend the water only just covers the tree/plant, so light is still available. Does it suffocate due to lack of oxygen? Does the water leach essential chemicals out of leaves? Both? Does the water just block enough light it starves? submitted by /u/IAMA_Printer_AMA [link] [comments]

Does the effectiveness of the tetanus vaccine (in a vaccinated person) reduce with repeated exposure to C. tetanii? Posted: 16 Dec 2019 10:51 AM PST put another way, does the (vaccinated) human body's resistance to the tetanus toxin reduce with each (or numerous) exposure events? submitted by /u/roraparooza [link] [comments]

How to get a standard deviation greater than value for a nonnegative number? Posted: 16 Dec 2019 11:59 AM PST I have seen in multiple presentations the author present a value of something that can't be negative (cost of healthcare, moles of product formed, survival time, etc) that will have a standard deviation that is greater than the value itself. While this isn't an issue for something that can be negative, what does this mean if you can only have a positive value? submitted by /u/DeadGatoBounce [link] [comments]

Is there a point at which a binary number will use less digits than a decimal number of the same value? Posted: 16 Dec 2019 08:02 AM PST submitted by /u/VerpinBeeping [link] [comments]

The explanation of the Coriolis force that everyone gives about the relative difference between linear velocities on Earth. Is that correct? Posted: 16 Dec 2019 07:31 AM PST https://www.youtube.com/watch?v=HIyBpi7B-dE This is a video that gives the same explanation. Mind you, it's not the only one. Every video/article online that attempts to explain the Coriolis force uses the same logic. I have even had professional lectures on universities where they attribute the Coriolis force on the relative difference of linear velocities. My question is simple: Is this explanation correct? From my experience and knowledge, it's not. The Coriolis force has nothing to do with initial linear velocities that are preserved due to inertia. It's a purely fictitious force that is a result of different observations from the perspective of a rotating frame of reference In fact the explanation of the above video, can't explain why there is still Coriolis force when the object moves on the meridional direction, e.g. when it moves along a constant latitude. I would like to know what are some of your opinions and if you agree with my statement. Thanks in advance. submitted by /u/alerommel [link] [comments]

What makes the eyes lubricated? Posted: 16 Dec 2019 09:28 AM PST Do they lubricate a fluid of their own or when you blink do you reapply a film? submitted by /u/fortnitefan8 [link] [comments]

Do we know of any systems with planets that formed from multiple protoplantary disks? Posted: 16 Dec 2019 11:26 AM PST For example, could there be a system where satellites are orbiting 60 or 90 degrees off each other? I realize that collisions would be at greater risk, and even gravitational affects from it could tear things apart submitted by /u/captcraigaroo [link] [comments]

What makes it so the eyes constantly stay in a moisturized state? Posted: 16 Dec 2019 04:44 AM PST Does the eye itself produce a film or when we blink does it reapply something? submitted by /u/mattmace8 [link] [comments]

Why do we need IPv6? Posted: 15 Dec 2019 07:47 PM PST So i get why IPv4 will be obsolete soon, we need more then 232 address spacess, sure, but why do we need a whopping 2128 addresses (basically billions of billions for every human). Wouldn't it be enough to have 264 possible addresses and therefore they are still relatively readable and it will still last for a few thousand years from now, or am I missing something out? submitted by /u/sergi42o [link] [comments]

Why does smooth water from a faucet ripple and fold when interrupted? Posted: 16 Dec 2019 04:06 AM PST Here is a video of what I mean. Pretty sure it is physics related. Maybe water tension? But I'm so lost trying to find an answer. submitted by /u/videovillain [link] [comments]

Why do we only see noticeable physiological effects with skeletal muscles? submitted by /u/Gonorrhea_NoduIe [link] [comments]

How is insulin purified after E. coli produces it? Posted: 15 Dec 2019 08:55 PM PST Obviously, insulin can be made by genetically engineered E. coli. But how is it separated from the bacteria? I know that the bacteria produces it, but how does it travel from 'in the vat' to 'in this solution you inject into yourself'? submitted by /u/Accelerator231 [link] [comments]

Can a bioengineered rubisco enzyme with improved enzyme kinetics be a potential solution in helping to mitigate carbon overproduction, climate change, and help with food yields? Posted: 15 Dec 2019 08:36 PM PST I am not a plant physiologist or a biochemist, but I do know a little bit about biology. I understand that rubisco is an enzyme found in plant chloroplasts that catalyzes the incorporation of atmospheric CO2 into ribulose-1,5-bisphosphate (RuBP). RuBP can then enter the rest of the Calvin cycle reactions. I've learned that rubisco has one of the slowest enzyme kinetic profiles, and considering that this enzyme facilitates atmospheric CO2 incorporation into organic molecules, wouldn't it be important, in terms of climate change and food yields, to genetically engineer an enzyme with faster kinetics? It seems like such a good solution but almost too good to be true or possible. submitted by /u/Practicals [link] [comments]

Question regarding lightspeed and perception of it’s effects? Posted: 15 Dec 2019 07:46 PM PST Random question popped into my mind. Say you are floating far enough away from our solar system to see all planetary bodies therein, but the sun is "off" (no light emitted), so you see none of it. Now say the sun turns on; what is the order of things you see, as you see them? Would you just see the sun appear, then slowly each planet in succession as the sunlight reaches them? submitted by /u/Borkso [link] [comments]

Why does moving in a hot bath make the water feel much hotter than remaining perfectly still in a hot bath? Posted: 15 Dec 2019 05:56 AM PST I assume its to do with my body actually cooling the water around me down? The difference is so severe that the temperature seems to go from reasonable to searing when moving. Thanks in advance. submitted by /u/Societyinflames [link] [comments]

Why are electrical wires not placed below ground? Posted: 15 Dec 2019 02:11 PM PST Less chance of disturbance, I would think. Can't be that much more expensive than erecting poles and fixing lines. Much more aesthetically pleasing... submitted by /u/squidjuggler [link] [comments]

Why does soda (carbonated beverages) taste different when they go flat? Posted: 15 Dec 2019 10:19 AM PST I assume that the carbonation does not have much flavor (if any) so why does it taste very different after you open a can/bottle and it sits for a while? submitted by /u/motzel [link] [comments]

What exactly causes vision loss in astronauts aboard the ISS? Posted: 15 Dec 2019 03:20 AM PST Interviews with Chris Hadfield describe what it is like going blind in space, and I've been fascinated by why space causes vision loss in astronauts. The inability to shed tears in space (requiring them to be wiped away) has always made me wonder what effect that might have on the anterior part of the eye. A little digging around about vision loss in space showed theories that it could be down to increased levels of cerebrospinal fluid causing intracranial pressure. I thought it might be something to do with blood pressure, though the measurements of astronauts' blood pressure when returning from the ISS varied greatly; some astronauts had low blood pressure but high levels of CSF. Some astronauts with vision loss were observed to have choroidal folding, this I know very little about as I'm a first year optometry student. If anyone could shed some light on this I would be grateful. Thank you for your time. submitted by /u/DNAmber [link] [comments]

How much heat does the earth lose to space? Posted: 14 Dec 2019 10:24 PM PST I hear a lot about global warming and it got me thinking that the earth must naturally lose a lot of heat out into space over any given period, so how much are we losing? submitted by /u/tjmaxal [link] [comments]

What would the inside of sun look like to the human eye? Posted: 14 Dec 2019 12:41 PM PST So yesterday I saw a documentary about the sun and how photons are created in the core of stars. When they are first created though, they have so much energy that are in the form of gamma and X rays, which aren't visible to the human eye. So if these photons don't become visible light until the outer layer of the sun, does that mean the inside of the sun would be invisible to us? submitted by /u/S3xseaTurtle [link] [comments]

Is there a theory, that explains why daily/common activities are often described by irregular verbs? Posted: 15 Dec 2019 05:31 AM PST I have the feeling like most irregular verbs in most languages are those you use often on a daily basis, like "see" "want" "go", etc. I stumbled upon this because I learned/tried to learn new European languages. My first theory was, that it's because they all developed from the Indo-European language family. But then I looked into the irregular verbs in Japanese. And their only irregular verbs are "to come" and "to do"! Sooo is there a theory that tries to explain this pattern? submitted by /u/josebert_ [link] [comments]

Is the act of shrugging socially learned or biologically learned? Posted: 15 Dec 2019 02:20 AM PST I believe emotions are universal, as are the displays of them in most cases, but there are cultural differences of expression.

If photons are electromagnetic radiation/the particles (bosons?) that transmit electromagnetic force, why don't magnetic and electric fields reflect/refract the way visible light does, even in different materials?

Why we don't see solar emission lines when we put sunlight through a prism but a continuous spectrum? Posted: 14 Dec 2019 07:50 AM PST When you put prism in the path of the sunlight you get a nice spectrum spread from red to violet (and beyond the visible part). Why do we get that spectrum? Why don't we see emission lines from hydrogen or helium? Where do other wavelengths come from? How do you "take out all those photons to see say He lines (how helium was first discovered)? I think I read somewhere you can sometimes see absorption lines from atmosphere gases, but why not original source bands? How does it work that we can determine composition of other stars or even exoplanets from their light if everything we get is "white"? Sorry for lots of questions, it just popped in my head. submitted by /u/Ishana92 [link] [comments]

Does the Earth's atmosphere wear away from the suns rays? (and is there a time limit?) Posted: 14 Dec 2019 06:30 PM PST Basically, does the Sun wear away at the Earth's atmosphere in the same way the sun UV rays wears away the colors on a poster? If so, is there a certain time limit of the atmosphere has to be worn out?

Why is the speed of heat conduction so different from the speed of sound in a solid material?

Why do female Reindeer grow antlers as well as the males? Why don't other Cervidae do this? Posted: 14 Dec 2019 01:07 PM PST I am wondering about antler growth in female Reindeer as compared to other Cervidae, where it is mostly just the males who grow and regrow their antlers. Often antler growth in other female Cervidae (ie. White Tailed Deer) is usually attributed to more testerone or some sort of "abnormality" but it is not percieved as abnormal for the female Reindeer. Why is it more common for the female Reindeer? What causes their growth? Thanks folks! submitted by /u/trolle222 [link] [comments]
