| How would having a fish in the ISS work? Posted: 21 Jun 2018 09:13 PM PDT I was puzzling this with my friends and we ended up with a lot of questions. We had two assumptions: the fish was in a bowl, and the bowl had just regular water in it. 1) Would the fish be able to get oxygen from the water? 2) Would it be possible for the fish to flap its fins and create an air bubble around it? That would presumably kill it. And beyond all this, would the fish be able to even handle being in 0 gravity? Thanks [link] [comments]  |

| Do certain languages have higher percentage of people who stutter? Posted: 22 Jun 2018 07:01 AM PDT I believe (as layman) that some sounds 'trigger' a stutter. Different languages have different sounds, so maybe there are languages that trigger stuttering more than other languages. And if so, which languages has the most people who stutter?

| Do immediate family members share a scent? Posted: 21 Jun 2018 08:25 PM PDT Downvote away if this is silly, but I'm sitting here wondering what my newborn smells like to my cats. Since my son is half my DNA and half my wife's, is his scent a mix of us as well? [link] [comments]  |
| How do you ground electronics in space? Posted: 22 Jun 2018 05:14 AM PDT Usually here on Earth I know we do this by sinking grounding rods into the earth. How does space based electronics do it? I assume they don't tote a giant tub of dirt up into space, as funny as that sounds. [link] [comments]  |
| Why do our voices crack/change when emotional? What is the cause? Posted: 22 Jun 2018 02:56 AM PDT It seems to happen with a bunch of emotions too. Whether angry, upset, nervous or whatever. [link] [comments]  |
| Posted: 21 Jun 2018 04:40 PM PDT I've been wondering if animals have ever been observed training their bodies. This could mean an animal running to practice it's stride, a monkey continually slamming a heavy stick like a human swings a hammer, etc. [link] [comments]  |
| Posted: 22 Jun 2018 12:02 AM PDT How does NASA and other countries space programs simulate a "zero gravity" experience for astronauts preparing to go to space? Are there ways to simulate an anti gravity force on earth, if so, how? [link] [comments]  |
| How do bird species pass the same songs and calls on through generations? Posted: 22 Jun 2018 03:38 AM PDT I understand that genes are passed on down generations, which helps determine birds' structure, size, plumage etc., and to a certain extent, behaviour. But something as specific as a very particular song or call with a certain number of notes at a certain speed with a high level complexity, which is incredibly accurate/similar over a vast geographical range and a vast time range too, through generation after generation? I'm not talking about birds that mimic other sounds, and I don't believe young birds learn songs or calls from their parents (birds such as the cuckoo never interact with their parents for example). Humans obviously learn language from others, and apply that to a genetic ability to make sounds with their throat and mouth. While birdsong isn't anywhere near as deep as human language, it is still complex. So is it really just developmental proteins containing instructions for behaviour as intricate as a bird's song, passed on genetically? How on earth can such information be stored? (I think I need to do more reading on genetics if that'st the case!) [link] [comments]  |
| Scientists find missing baryonic matter. Why is this significant? Posted: 21 Jun 2018 09:37 PM PDT Can someone explain why the significance of this discovery? Link to article here [link] [comments]  |
| Has there been an attempt to create a unifying measuring system? Posted: 21 Jun 2018 05:40 PM PDT By measuring system I mean like "metric", "empiral" etc. And by unifying, I mean where all constants in well known formula (permeability, permittivity of vacuum, etc) resolve down to 1? I've always felt that if you scaled the metric system carefully you could effectively get rid of some, most, or even all constants. [link] [comments]  |

| Posted: 21 Jun 2018 07:32 PM PDT It is observed that after sucking liquid medicine from vial into syringe, there is air left in it. The doctor holds syringe in vertical position with needle at top and pushes piston from bottom till the air gets removed and little bit of liquid comes from needle. And then it is injected in body. What if some air remains in syringe and gets injected in body? What effect will it have on our body? [link] [comments]  |
| How often are new species discovered? Posted: 21 Jun 2018 04:41 PM PDT Does anyone know roughly how many species (of any domain) humans discover per week/month? And if so, what are the more common types that get discovered? I feel like most of them would either be microbial or insects. Thanks! [link] [comments]  |
| why are different kinds of disinfectants used in different situations? Posted: 22 Jun 2018 12:08 AM PDT i'm specifically thinking of iodine hydrogen peroxide and rubbing alcohol ex. rubbing alcohol is used for shots iodine for surgeries and hydrogen peroxide for at home use on cuts and scrapes and i'm just wondering why they are used this way (my last post was removed for this so i would just like to clarify that i am in no need of advice and i will not change my general health practices based on any answers i receive i am only wondering why doctors recommend or use these disinfectants in these situations) [link] [comments]  |
| Can insects, reptiles, or fish have actual emotions such as happy, sad, angry, or scared? Posted: 21 Jun 2018 05:45 PM PDT Not instincts, but actual emotions. Something outside of what their instincts tell them to do. [link] [comments]  |
| Are protons and neutrons polar or nonpolar? Posted: 21 Jun 2018 10:26 PM PDT Similar to how a water molecule is polar because part of the molecule is positively charged and part of it is negatively charged, I've recently been wondering if a proton or neutron is polar due to the placement of its quarks. There's no good information on this question online that's not in relation to its spin, or antiquarks, or something. [link] [comments]  |
| Do all observers agree on where their respective light cones are, regardless of reference frame? Posted: 21 Jun 2018 06:24 PM PDT And additionally: Do two observers with light cones that overlap agree on the sequence of events within that overlapping volume? [link] [comments]  |
