| What happens to fish that die near the poles? Posted: 26 Dec 2017 10:50 AM PST Some fish have to die of natural causes, and since freezing temperatures preserve food, is it possible that there is a massive graveyard of fish that have died and are just sitting on the ocean floor near the land masses frozen in time? Or do they float off into warmer waters, then are eaten? [link] [comments]  |

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 27 Dec 2017 07:06 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |

| How is having two colors depending on the angle possible? Posted: 27 Dec 2017 07:24 AM PST A friend of mine extracted a substance that is green if you shine light from the bottom and red if you shine light from the side onto it. How does it work? [link] [comments]  |
| Do all galaxies have the same elements? Posted: 27 Dec 2017 07:07 AM PST Always wondered if that is true or not, like the composition of the space in this galaxy is different from other. *sorry for bad english or science things said I'm dumb. [link] [comments]  |
| Posted: 26 Dec 2017 02:35 PM PST Also, are all "plants" types important to an ecosystem because they are autotrophs (apart from some archea bacteria)? The basic ecosystem (for me) is: herbivore, carnivore and omnivore. Mosquitoes - do they help in pollination? (like insects do). If answer is no then one can also argue that even humans are not required, but I'd say the "brain power" we've got changes the answer to "yes" (imo). Just a thought, (consider) for female aedes mosquito, the virus apparently lives in her, so in a way the mosquito is helping the virus, does it count as a role? At the same time viruses are neither living nor dead so do they really need a place to "live", also if the mosquitoes suddenly vanish can the virus "live" somewhere else, is there any problem here?

| Posted: 27 Dec 2017 04:53 AM PST If I come across a strong beta emitter, why couldn't I just use alpha radiation to neutralize it and just create normal Helium gas? It seems like these two radiation sources should de-ionize each other? [link] [comments]  |
| Why doesn't sunrise and sunset turn on the same day during winter solstice? Posted: 26 Dec 2017 09:12 AM PST I noticed on my weather station at home that around the time of winter solstice, the evenings started getting longer while the sun was still rising later in the day. This is only for a couple of days before the sun starts rising earlier again. I always thought that sunrise and sunset turned simoultaneously, but this appears to not be the case. What is the reason behind this? Does this happen in the summer as well? I live in Norway if that could have anything to do with it. [link] [comments]  |
| What would be needed to cause a nuclear reactor to explode? Posted: 26 Dec 2017 03:45 PM PST I've read that even if you remove cooling and let it overheat, nuclear reactors wouldn't explode, they'd just meltdown and leak radiation. What reasons, if any, would cause it to explode, instead of just melting down? [link] [comments]  |
| What decides a battery voltage? Posted: 26 Dec 2017 12:58 PM PST I've got a bunch of Lipo batteries of various sizes. They all have 3.7v per cell. Is there a reason it was standardised to 3.7v? [link] [comments]  |
| When an embryo is cryogenically frozen, is it alive or dead? Posted: 27 Dec 2017 01:57 AM PST I guess we'd first have to determine what distinguishes an organism from being alive or dead and the attributes of these states, and then apply that to frozen embryos. But it seems like they'd be considered neither... [link] [comments]  |

| Are there EM waves (noise) being constantly produced by a DC current on a real conductor? Posted: 26 Dec 2017 10:57 AM PST In a conductor, the charge carriers move with an average speed in the direction of the flow (drift velocity), however, each carge carrier is not moving at a constant speed - they are propagating randomly through the conductor, colliding with it's structure and moving in many directions that are not solely the direction of the flow. This means that the charge carriers are not moving with constant speed. If they are suffering deviations in the direction and speed as they move, this means they suffer accellerations through their path, even if the average speed is kept the same in a larger time scale. So, my question is: Shouldn't they produce EM waves because of that? And of what order would be frequency of those EM waves (the frequency in which they suffer these collisions)? The agitation of charge carriers by an AC current surely produces EM waves and I know that, but here i'm asking about EM waves being produced not because of an AC current, but due to this erratic movement they follow in a DC flow. Thanks! [link] [comments]  |
| Is there anyway to create low-background steel today? Posted: 26 Dec 2017 03:38 PM PST I recently learned about low-background steel on a TIL. Low-background steel can't be made because of radionuclides in the air caused by nuclear tests. So I started wondering if there is anyway to create low-background steel now or if there is a risk of running out of low-background steel to use. [link] [comments]  |
| Posted: 26 Dec 2017 07:42 AM PST There are basically 2 ideas as to what's in a black hole. Either it's a single point with infinite density or it's a bundle of mass that's managed to become smaller than its Scherz child radius. If it turns out they're perfect spheres then we know it's a point of infinite density. If it's shown they aren't perfect spheres then we know it's not a single point. What would either of these discoveries indicate for theoretical physics and physics in general [link] [comments]  |

| Posted: 26 Dec 2017 04:12 AM PST I would assume smaller diameter and more turns are better, because I see commercial electronics with them, but I think that is only to save space and material. After a bit of research, I found out (this was a while so I could be wrong) that: doubling wire diameter doubles the strength of the electromagnetic field, and that doubling the amount of turns also doubles the strength of the electromagnetic field. Therefore, if I double the diameter, the amount of turns would halve, resulting in the same electromagnetic strength (assuming negligible wire insulation). Do industrial electromagnets have thicker coils? And for what reason would that be? P.S. While writing this post I realized that thicker wires would be able to carry more current, but I would still like a second opinion. Thanks in advance! Edit: Thank you for all your answers! I will take it all into consideration. [link] [comments]  |
