| Posted: 11 May 2019 05:42 AM PDT It's my understanding that a fever is an autoimmune response to the common cold, flu, etc. By raising the body's internal temperature, it makes it considerably more difficult for the infection to reproduce, and allows the immune system to fight off the disease more efficiently. With this in mind, why would a doctor prescribe a medicine that reduces your fever? Is this just to make you feel less terrible, or does this actually help fight the infection? It seems (based on my limited understanding) that it would cure you more quickly to just suffer through the fever for a couple days. [link] [comments]  |

| How do rocket scientists ensure that a rocket's mass distribution is balanced throughout a launch? Posted: 11 May 2019 04:41 AM PDT I've been playing a lot of Kerbal Space Program (game where you basically run a space program), and I always need to make sure that my launch vehicle (rocket) is either incredibly balanced, has control surfaces to compensate, or the magic reaction wheels. Otherwise my next stop is the ground, not orbit. Considering the constraints that actual rocket scientists face, what options do they have available to make sure that a rocket doesn't spin out of control? [link] [comments]  |
| In capillary effect: where do liquids take the energy from to "climb up" objects? Posted: 11 May 2019 06:19 AM PDT We asked our physics teacher this question and he didn't know the answear nor could anyone figure it out. I'm really curious about this topic since and couldn't find the answear anywhere on the Internet. [link] [comments]  |
| Is there anything “special” about the visible spectrum? Posted: 10 May 2019 08:44 PM PDT Our eyes perceive light in the visible spectrum, which is just one small part of the full electromagnetic spectrum. We can differentiate hundreds of colors out of this relatively narrow spectrum of light. My question is, is there anything special about the part of the EM spectrum that our eyes can see that allow us to distinguish red from blue from yellow? If we instead had evolved to "see" in what we consider the UV or microwave regimes, would an eye be able to perceive different colors? In other words, is the visible spectrum the only spectrum where we could have so much differentiation in color? [link] [comments]  |

| How do plants determine which leaves "die" first? Posted: 10 May 2019 12:46 PM PDT I have a Dragon Tree that I keep in my office. http://www.costafarms.com/plants/madagascar-dragon-tree Every once in awhile, I'll have a brown leaf randomly appear from either not enough sun or not enough water. How does the plant determine which leaf is the one to die while the others remain fully green? [link] [comments]  |
| Can cosmic radiation trigger neurons in any significant or cognitively noticeable way? Posted: 10 May 2019 04:31 PM PDT I'm led to understand cosmic radiation can trigger transistors within electronic circuits. Was curious if it could also energise a neural pathway in the brain to any degree [link] [comments]  |
| Do people with verbal tourette syndrome also have those tics when speaking in foreign languages? Posted: 10 May 2019 06:59 AM PDT Hey, I saw a video of a guy with verbal tourette syndrome (swearing and motoric tics) said that he had conversations in foreign languages where his tourette (at least the verbal part) was suppressed. Now I wanted to know if it is common for this syndrom or it is only a few people? And does it only affect when speaking and not thinking? If it is common is it a therapy form for them to think in those or even change their life in only speaking foreign languages? I couldn't find anything related to this so i would really appreciate it if someone can answer the question. Greetings [link] [comments]  |
| What is the benefit of using telescopes outside of the visible spectrum? Posted: 10 May 2019 10:14 AM PDT What information can you gather by observing other celestial bodies in radio/microwave/xray etc. that you couldnt in the visible spectrum? [link] [comments]  |

| Posted: 10 May 2019 06:58 AM PDT Do cats or dogs show preference for specific breeds or traits in a non-natural environment such as a breeding programme or an small predetermined set of choices? Has any study like this been done? If presented a choice in such an environment do the animals still go for some specific trait reliably or is it just any hole's a goal / random selection of breeding partner? [link] [comments]  |
| Why are mesons and gluons considered the same force but do (largely?) different things? Posted: 10 May 2019 02:04 PM PDT Laman here. My educational level is occasionally browsing Wikipedia and talking about it with other amateurs of the subject. I don't understand how the strong nuclear force "knows" the difference between holding hadrons together via gluons vs holding nuclei together via mesons. Also, why aren't mesons represented as a boson in the standard model? Additionally, Wikipedia says mesons are unstable particles (lasting hundredths of a microsecond), but if so how do nuclei stay held together? Are mesons constantly created to do that job, and if so, how? Additionally additionally, it says mesons are comprised of one quark and one anti-quark held by strong interactions. Why don't they just annihilate themselves when they bond? [link] [comments]  |

| How come the most sensitive seismic sensor we have ever made is on Mars? Posted: 10 May 2019 05:19 AM PDT Flared with planetary science, cos I guess Geology isn't a science or something so, I read this NS article at lunch today which, amongst other things, implies that the seismic sensor set up that they have on Mars is better than any operating on Earth. I have 2 questions The article states that the quake they detected was so slight that the very best sensors currently in service on Earth "might" have detected it. It goes on to state that 3 even smaller quakes were detected in March and April, so weak that "the best detectors on earth would never have been able to spot them". Now, I get that we send very expensive stuff into space but, is it really true that the best seismic sensor that humanity has in service (perhaps has ever made) is on Mars? Maybe there is no use for that level of sensitivity on an earth bound sensor setup? I would have thought science would have use for such a thing down here Supplemental question (and perhaps stupid / completely incorrect, I admit I didn't use my google smarts before posting): I thought Mars and the moon were Geologically dead ... so what is the deal with moon / mars quakes, what causes them what are the cores / mantles etc made of etc etc (or am I just wrong and both are still geologically active?)

| Which came first the ribosome or DNA? Posted: 10 May 2019 09:24 AM PDT I understand to an approximation that a ribosome is a complex machine made from proteins that allow creation of more proteins by interpreting the DNA code as chains of amino acids. Given that ribosomes are made from proteins and proteins through the use of ribosomes interpreting a code written in DNA. What are the various explanations of how this process begins?
