Is educational attainment linked to genetics, and if so why? Posted: 23 Oct 2019 10:42 AM PDT There was an article in the Economist today that seemed to indicate researchers could tell from a person's genetics whether they had decided to stay or leave a coal mining area. Has there been extensive research to back up the claim that education has a genetic factor? submitted by /u/hngysh [link] [comments]

why is pure water not conducting electricity due to autoprotolysis? Posted: 23 Oct 2019 02:11 AM PDT Confused high school student here. We've recently covered acids and bases, and the autoprotolysis of water. If some molecules in pure water can become positive hydronium ions and negative hydroxide ions, why do we always conclude that pure water can't conduct electricity? Are these ion concentrations insignificantly small? Any help is greatly appreciated! submitted by /u/Daniel01m [link] [comments]

Does childhood participation in lotteries have any impact on whether or not a person is likely to develop a gambling problem (then or later in life)? Posted: 23 Oct 2019 01:47 AM PDT Current controversy about loot-boxes is computer games is that they are wrong because they prey on children and they are often characterized as a form of gambling (usually when real money is involved). But is there any scientific knowledge on whether participation in lotteries change gambling tendencies amongst children? submitted by /u/VoiceOfRealson [link] [comments]

How is plasma generated? and what is it really? Posted: 22 Oct 2019 07:51 PM PDT I am looking for a more nuanced answer in truth, what is it specifically about fast moving molecules that causes ionization? ​ my hypothesis is that the atoms themselves are able to knock out electrons from other atoms and you should have some sort of statistical distribution of ionized and non ionized particles, but in a plasma you have mostly ionised particles, is this correct ? , whats the reality? ​ also in regards to plasmas do they lose all of their electrons or just some of their electrons for example does a plasma alumininum lose the outer shell of electrons or all of them . ​ thank you very much to whoever answers submitted by /u/robespierrem [link] [comments]

Does applying current to water affect its refractive index? Posted: 22 Oct 2019 06:02 PM PDT I came to know that refraction in the glass is caused by electric fields interacting with the incoming photons. So is it possible to change refractive index of water by applying electric field? submitted by /u/ted7843 [link] [comments]

Was there a notable difference in oxygen percentages in ancient human history (like 100,000 yrs ago) vs the ~20.9% of today? Posted: 22 Oct 2019 07:16 PM PDT I was talking to someone about atmospheric oxygen levels, algae and land plant life are currently experiencing some issues, and apparently human brains die at around 19.5% oxygen (this part has been dealt with in the comments as incorrect information, thank you) I had mentioned this and they argued that oxygen levels were different before in the past. There's been a dip of about 0.06% since 1992 according to oxygen levels records I could find. If that continued it'd take maybe 600-700 years to kill us all. So I'm not that immediately worried. But I cannot find data about percentages from thousands of years ago, assuming human brains require the same amount of oxygen I suspect the percentage was never very close to 19.5%. submitted by /u/Colddigger [link] [comments]

Does dissolution affect volume differently than just addition? Posted: 22 Oct 2019 01:05 PM PDT Say I have two glasses of x amount of water. If I add y amount of salt to one and y amount rocks to the other, will both volumes be x+y submitted by /u/20-CharactersAllowed [link] [comments]

What's going on with the prints left behind by the stuffed mushrooms we ate last night? Posted: 22 Oct 2019 03:30 PM PDT Here is an image and a short video https://imgur.com/gallery/kS9wCJ8 We cooked and ate stuffed mushrooms last night and after getting home from work today, we noticed very strange patterns left behind on the plate.

Why do statistics behave differently when identical particles are involved? Posted: 22 Oct 2019 08:02 AM PDT I'm borrowing the example from this wikipedia article. Let's say I have two indistinguishable bosons, each of which can exist in two states, |0> and |1>. If I put the two particles together in a noisy environment, let them evolve for some time, and then measure their states, I have a 33% probability each of measuring |00>, |01>, or |11>. This makes sense on some level --- the combined system had three possible states, all of the same energy, and a uniform distribution over those states maximizes entropy. Obviously, this doesn't generalize to normal macroscopic systems. If I put two coins in a cup, shake them for a while, and observe their state, I would expect to find two heads with 25% probability, two tails with 25% probability, and 1 heads and one tails with 50% probability. Of course, macroscopic coins are not indistinguishable, but where exactly does indistinguishably change the statistics so fundamentally? Is it at the time of observation? If I observed the state with a sufficiently low-resolution camera, that could resolve heads and tails, but not distinguish the two coins by any markings, would my observations mimic the quantum-mechanical case? Or is the indistinguishably important while the coins/particles are time-evolving in a noisy environment? Of course, I know that quantum mechanics are inherently counter-intuitive, and I shouldn't expect my normal intuitions to apply. However, the classical behavior should be a limiting case of the quantum-mechanical behavior, and I don't see where the boundaries between the classical and quantum-mechanical behavior lies. In principle, could one construct two atom-for-atom identical coins, put them in Schrödinger's box, shake it, and expect two heads with 33% probability? submitted by /u/person594 [link] [comments]

How does maintaing methane levels influence global heating? Posted: 22 Oct 2019 04:19 AM PDT I best explain. First of all I am a scientist myself, though is slightly outside my comfort zone. I'm hoping a greenhouse gas specialist could answer. Methane breaksdown over 8-10 years. So lets say that every year we produce exactly the same amount of methane, we get to a state where the methane is being put into the atmosphere at the same rate by which it is breaking down (let's forget about CO2 and other GHGs for now). If atmoshpheric methane remains constant, will it maintain the current temperatue (pre-industrial +1.5c)? or will it continually have a warming effect, pushing up global temperatures. To word it a different away: Is the impact of methane in the atmosphere mainly from the simple abundance of it. Or is it the abundance of it multiplied by it's time present. I appreciate it is a bit more nuanced that I am making it, but I hope my question comes across. Please ask if I am not being clear enough. submitted by /u/ac13332 [link] [comments]

Why Do Drugs like Losartan and other ARB's take weeks to have full effect? Posted: 22 Oct 2019 06:20 AM PDT The manuals for Losartan says that while the initial dose will be in effect in 4-6 hours after ingestion, the full effect of the drug will take a few weeks. Why is that? submitted by /u/isowater [link] [comments]

Why can you crumble paper but not fabric? Posted: 22 Oct 2019 06:48 AM PDT When you fold or crumple paper it stays this way and it is really hard to get rid of the folding lines (if even possible). If you try the same with fabric it does not work and you cannot tell whether a piece of fabric has been folded before or not. Why is that? Edit: I misspelled crumple in the title but cannot change it. So the question is about crumpling and not crumbling. submitted by /u/StNimmerlein [link] [comments]

Eye lense - help me understand? Posted: 22 Oct 2019 04:29 AM PDT With reference to the lense in an eye. Why do they say that when the lense is round (versus flat) that the cilliary muscle is relaxed and the syspensory ligament is TIGHT? Surely the cillary muscle becomes longer when relaxed (versus short) when it's contracted? So that extra length in the muscle should allow the ligament (which is not elastic) to be SLACK( not tight)? submitted by /u/SSeah [link] [comments]

How exactly is memory stored in our brain? Posted: 21 Oct 2019 11:41 AM PDT I mean like I know it is stored in specific areas of the brain but at the molecular level,how does it "stay"? submitted by /u/Riki1996 [link] [comments]

Do live vaccines grown in human embryos have the potential to affect our DNA? Posted: 21 Oct 2019 03:05 PM PDT So I had this anti vaxer in my class bring up that certain live vaccines are propagated in human embryos and that if the embryo has a predisposition to cancer it would be passed to us. My professor isn't too bright and didn't know what to reply with. Can someone give me a scientific explanation of why this is not true so that I can at least debate against this person? I know that the virus is replicated. I don't know whether or not it's an RNA or DNA virus. If RNA I know it would replicate outside of the nucleus and have no contact with our DNA. Any clarification? submitted by /u/prometheus181 [link] [comments]

How does the stomach replenish loss of acid? Posted: 21 Oct 2019 06:26 AM PDT When you vomit, and even just through the regular process of digestion the stomach looses some acid, how does it "refill" itself? submitted by /u/Farkle_Griffen [link] [comments]

How do the center of planets/stars behave? Posted: 21 Oct 2019 06:07 AM PDT Is the material in the center of planets and stars just held there by the pressure of everything above it. Is it "weightless" in the center of planets/stars? It seems counter initiative that there is more mass outside the very center point of a planet/star so shouldn't that gravity be pulling it apart all around and away from the center but at the same time all that mass is pulling itself inward because to an outside point there's more mass towards the center were the matter is being pulled and making that pressure that the center feels. submitted by /u/pwn3dbyth3n00b [link] [comments]

How Do The Electronics Of LCD/OLED Displays Work? Posted: 21 Oct 2019 01:41 AM PDT To clarify, I'm not asking about the optical side of things. I understand how you can create an image by activating/deactivating LEDs or light blocking liquid crystals in a large grid matrix. However, since a typical display has millions of pixels you wouldn't be able to just run a wire from the controller to every single individual pixel. I'm assuming it works with some kind of periodic timed signal similar to old cathode ray tubes, but how do the actual electronic components for this work? How does the display controller select which of the millions of pixels it's talking to? submitted by /u/Hellothere_1 [link] [comments]

Posted: 20 Oct 2019 04:43 PM PDT In 1932, the Dutch government completed the damming of the Zuiderzee, a shallow salt water bay after devastating floods. Since then, the former sea has been turned into a freshwater lake, and is the subject of ongoing land reclamation projects Did the damming of the Zuiderzee and changing of the water from a salt water sea to a freshwater lake have negative ecological effects?

What genes are conserved in animal phyla with bilateral symmetry? What do they do? Posted: 20 Oct 2019 03:13 PM PDT Structural symmetry is more of an emergent phenomenon than something that is hard-coded into the genes, but phyla that have left-right symmetry in common presumably have common genes that are conserved (more than genes shared with all life, less than let's say genes shared among primates).
