| Are there any challenges for parasites living in animal blood? Posted: 21 Sep 2017 05:32 PM PDT As far as I know, most habitats have qualities that challenge inhabitants, so I was wondering how a blood habitat would challenge a parasite living in it. [link] [comments]  |
| What happens to heavy elements in a star? Posted: 22 Sep 2017 04:20 AM PDT I know that stars produce them when they explode, and that's the google result that is hard to dig through for an answer to this, but as the title says; What happens to heavy elements in a star? Do they get ejected, do they coalesce and get pushed aside in the core, or what? Edit: I should clarify, I looked up heavy elements and apparently that means anything over #92 on the periodic table. I really just meant any metals, like gold as an example because it's relatable. [link] [comments]  |

| Posted: 22 Sep 2017 01:52 AM PDT I understand the clinical side of ptsd but not the neurological side and am interested in finding out more, but don't know where to start or what the basics are. My preexisting knowledge is a B+ worth of Brain and Cognition five years ago in my undergrad. I presume there'd be arousal in the amygdala because it is fear inducing and the temporal lobes because it is a memory but that is guess work. Thank you for your time! [link] [comments]  |

| Is it possible to crack/shatter a quartz (or any piezoelectric material) with enough electricity? Posted: 21 Sep 2017 11:42 PM PDT Will it crack, explode, shatter, or just melt when too much voltage is applied? [link] [comments]  |
| Will cooling a piece of plastic increase its rigidity? Posted: 21 Sep 2017 11:37 PM PDT Since getting it hot has the opposite effect (melting), if I stick a piece of plastic in the freezer will this make it more rigid? [link] [comments]  |
| Can trapped charged particles escape the Van Allen Belts? If so, how? Posted: 21 Sep 2017 03:36 PM PDT I teach a general astronomy course at my university. While discussing the Earth's magnetosphere and the Van Allen Belts, a student asked if the radiation was just building up or if a portion of it could escape somehow. I didn't know off the top of my head, so rather than BS an answer, I told them I'd find out and report back. A quick google and wikipedia search hasn't provided me with a succinct answer, so I'm hoping reddit can help me out. My best guess is that random collisions give random particles enough energy to escape from the belts, but I'm not sure. [link] [comments]  |

| How was the modern science of photosynthesis and respiration discovered? Posted: 21 Sep 2017 02:11 PM PDT I'm a second level science teacher and I often get asked when teaching photosynthesis & respiration "how did people discover this?" I can never give a definite answer. I'm aware how it was originally discovered ,but I want to be able to give the answer as to how the electron pathways and things like the Krebs cycle were discovered. Thanks [link] [comments]  |
| Why do bubbles in a glass or cup tend to move to the edges and stay there? Posted: 21 Sep 2017 09:38 PM PDT I don't mean carbonation. When I pour a coffee or something, the bubbles are all spread out and then "migrate" to the sides of the cup, even if you slosh it around a little. [link] [comments]  |
| What, if anything, are we doing to reduce waste buildup orbiting earth? Posted: 21 Sep 2017 07:37 PM PDT From what i know, it will soon become increasingly more difficult to launch spacecraft due to a field of it growing in our orbit. Could we somehow pull or push it into earths atmosphere for it to burn up? [link] [comments]  |

| How exactly do scents just "disappear"? Posted: 21 Sep 2017 11:12 PM PDT How do scents disappear? From what i understand scent is caused by small particles, but as long add those particles exist, shouldn't the smell last forever? For example, if i were to spray perfume into a pillow, i would expect the scent to last indefinitely until i wash it since the particles are still on the pillow. [link] [comments]  |
| If sea level is rising, why are the beaches I know still the same size and shape? Posted: 21 Sep 2017 10:20 AM PDT It seems pretty clear that sea level is rising (3mm a year): https://oceanservice.noaa.gov/facts/sealevel.html That being the case, shouldn't that be obvious when looking at beaches and other coastlines? All the coastlines I know well (Northern Europe) haven't noticeably changed in the last 20 years and looking at old photos, haven't changed in over 100. I could understand the argument that some areas rise while others fall for various reasons but, again, looking at historical photos of other regions, the story is the same. So why doesn't sea level seem to be rising to a layperson when the actual rise is significant? [link] [comments]  |
