| Why do salt crystals form in almost perfect cubes? Posted: 16 Sep 2018 05:19 AM PDT At the beginning of last summer I left a bottle with a salt and water substance out in the living room. when we came back from vacation the water was gone and in bottle salt crystals had formed. Now what I don't understand is how the crystals formed in almost perfect cubes. Shouldn't there just be a thick flat layer of salt at the bottom? [link] [comments]  |
| Is there a connection between the age of newborns mother and the life expectancy of the baby? Posted: 16 Sep 2018 03:31 AM PDT For example will a baby born to a mother who is 20 have a longer life expectancy of a baby born to a mother who is 50 or vice versa? [link] [comments]  |

| Posted: 16 Sep 2018 07:29 AM PDT I know that some, but not all, Lowland cities experienced drought and/or famine during the Abandonment. I was curious whether the possible dietary stress from this several century event had an effect on the epigenetics of Maya people in the subsequent Postclassic or even historic/modern periods. I understand that preservation of skeletal remains in the region is not great and that this question may be unanswerable at this time. [link] [comments]  |
| Posted: 16 Sep 2018 04:06 AM PDT After getting a transplant the body is constantly trying to reject the new organ, despite it being healthy human tissue doing it's job, and despite the rejection probably leading to death. What makes the immune system see, for example, my original lungs as "mine" but my transplanted lungs as an "invader"? AFAIK the only current way to manage this problem is to cripple the immune system so it can't do its job, which brings along it's own set of problems. Is there any work being done in the direction of convincing the immune system that the new tissue belongs, or at least some more targeted way to hide just that tissue from the immune system?

| Why is Tantalum the rarest stable element in the solar system? Posted: 15 Sep 2018 10:40 AM PDT Can anyone here explain why it's abundance is so low in "simple" terms? What the heck is up with this neat element? [link] [comments]  |

| Posted: 15 Sep 2018 08:46 PM PDT my car requires 89-octane fuel or above in order to run smoothly. i've never really questioned it–i pay for the more expensive fuel and move on. but what does this mean? what makes a higher grade fuel, and why is it that certain engines can only function with higher-grade fuels? if i put 87-octane fuel in my car, would it run, just poorly, or would it not work at all?

| Are incest restrictions a social construct or do they exist in other animals? Posted: 15 Sep 2018 01:57 PM PDT We've been watching the local deer over the past few years. A year or two ago we had a rare set of triplets born: a buck and two does. They're still hanging out together... along with two new additions. My wife and I have been wondering if the new pair could be the prodigy of the buck and a sister or if another buck was responsible. That led us to the greater issue: is the prohibition against incest social or does it exist on a more fundamental hard-wired level? Is there a general biological imperative to avoid mating with siblings/close relatives? Does it vary among species? Do primates treat incest differently than dogs, for example? What are the resultant problems (provided inbreeding doesn't recur multiple times across generations)? [link] [comments]  |

| Why do protons have multiple combinations of color associated with their quarks? Posted: 15 Sep 2018 12:06 PM PDT From my really basic understanding of QCD, I'm lead to believe that quarks need to exist in a singlet state with no observable color ("white"). As an example, if we've got a red up quark, a blue up quark, and a green down quark, why do these quarks exchange gluons to change their respective colors if they're already in a singlet state? And a follow-up question: why are singlets formed by quark-antiquark pairs not as stable as baryons? [link] [comments]  |

| Posted: 15 Sep 2018 03:57 PM PDT I'm reading it's from the Coriolis force, which is the earth rotating. Does this mean as the hurricane spins it drains angular momentum from the earth's rotation? Secondary question: reading that hurricanes form when warm water in the ocean evaporates. This cools the ocean. Also read that hurricanes emit infrared light into space. Is this a cooling effect on earth as energy is lost into space? [link] [comments]  |
| Emotional behavior in humans and other animals and their neural underpinnings, are they comparable? Posted: 15 Sep 2018 03:55 PM PDT Much of research on the neural basis of emotional behavior is carried out in mices and other animals. My questions is: to what extent are the findings from those studies applicable to the comprehension of the neural basis of human emotional behavior? [link] [comments]  |
