| Posted: 09 Feb 2019 05:04 PM PST Both men and women have nocturnal tumescences, (erections) in their genitals while sleeping due to the lack of norepinephrine in the blood during REM sleep But as men get older NPT (nocturnal penile tumescences) decrese and if they ever reach full erectile dysfunction they stop completely My question now goes for women As women age, do they loose clitoral capacity? Can their clitoris still receive sexual stimulation and respond to it if they're 90 years old for example? Or 100 years? Do they ever stop getting nocturnal clitoral tumescences? [link] [comments]  |
| What happens to the central nervous system of a caterpillar when it turns into a butterfly? Posted: 10 Feb 2019 02:56 AM PST So we all know that when a caterpillar hatches it's main purpose is to grow and become "fatter". But after it encapsulates in a cocoon it is dissolved by enzymes into a protein fluid and special cell groups that are called "imaginal discs". Those cells take the nutrients from the fluid to turn into adult body parts. My question is: Is the whole caterpillar/larva dissolved or are certain parts preserved especially the central nervous system? Because the first scenario would mean that it sacrifices itself for a some kind of adult "clone" of itself. All previous memories (I know those are extremely limited in insects) would be lost, creating a new life form with only the genetic information in common. [link] [comments]  |
| Why is air resistance proportionally squared to speed? Posted: 10 Feb 2019 05:23 AM PST Please explain in geometric terms. Such as( the faster you go, the closer the air molecules become quashed, adding to the resistive force. Also if you can, please explain mathematically as well. Thank you [link] [comments]  |
| Posted: 09 Feb 2019 06:41 PM PST Title pretty much says it all, i've just been thinking about it and how it would work. As a bonus question, if we were to travel to the cut off point of the ice and dig through it, how far down could the average human get with current-gen technology? [link] [comments]  |

| How much of a role does solar wind play in the earth's climate? Posted: 10 Feb 2019 12:56 AM PST I wasn't sure whether to flair this as astronomy, earth sciences, or planetary sciences, but it's certainly not political science and have no intention of stirring that pot. My question basically has to do with the sun's role in our climate, and if there are any notable correlations in our planet's climate trends and other planets in the solar system. I would imagine that the sun doesn't output a fixed amount of energy and I'd be very surprised if there wasn't a great deal of variance over time. I'm not sure if 'solar wind' is the correct term so please forgive me if the question was ignorantly phrased. [link] [comments]  |

| Posted: 09 Feb 2019 04:54 PM PST I was watching this video about every known nuclear bomb test throughout history. There are parts throughout history where dozens have been tested in a single year. However, when people discuss nuclear war, the resulting global winter and nuclear fallout are always brought up, and yet we haven't experienced anything like this, to my knowledge. Of course during a nuclear war, we anticipate the worst-case scenario in which hundreds go off at a single time. However, even during a period where we're testing them very frequently, it seems we don't even experience minuscule effects on our climate. [link] [comments]  |
| Why does the FCC place occupational limits on non-ionizing RF exposure? Posted: 09 Feb 2019 11:22 PM PST The only concrete explanation this paper from the FCC gives (PDF) is the potential for the heating of body tissues. Is that the only current reason? Edit: When I say "occupational limits," I mean that the warning signs posted about high levels of RF energy are almost always placed for technicians that service transmitters, rather than the public.

| What is the relationship between phase and enthalpy of a fluid? Posted: 10 Feb 2019 07:51 AM PST Not a chemist, but I am using a fluid flow simulator where one can set up a source that pours fluid into a system. The only parameters to set a source by user are flow rate and enthalpy. I assume system's pressure and temperature will define fluid's phase. But what would be the impact of the enthalpy as a parameter that can be set. [link] [comments]  |

| Why is there so much variety in hair? Posted: 09 Feb 2019 08:15 PM PST There are obviously differences, but most features tend to be the same for most people, and those that are different, like different skin colors, have evolutionary explanations. I'm curious how/why so much variation in hair evolved. There are vastly different achievable lengths, textures, and somewhat colors. Is it just more susceptible to keeping mutations in the population since it has little actual survival benefit? Since different ethnicities seem to have similar textures or colors among themselves, it would seem that certain features do give evolutionary benefits, but I can't imagine what they could be.

| Are there physical changes happening in the ear when we wake from sleep? Posted: 10 Feb 2019 07:28 AM PST I tried googling around for the answer and came across a lot of information about how the brain processes information from the ears during sleep etc, but I'm wondering if there is actual physical movement of parts of the ear when we're in the process of waking up. When I gain consciousness in the morning, I can "sense" (over a very brief period of time, like.. 2 seconds) my hearing coming into focus. I imagine that is probably just my brain booting up but I'm wondering if that also "wakes" the ear into a different physical configuration, and if we know if that is something that happens rapidly (on the scale of seconds or less).

| Why is in the Alveolar gas equation the pressure of water subtracted from the atmospheric pressure? Posted: 10 Feb 2019 07:27 AM PST I would have guessed that it would be added on top of the atm-pressure. Any help is much appreciated! [link] [comments]  |

| How to monoamine oxidase inhibitors cause hypotension? Posted: 10 Feb 2019 07:12 AM PST My pharmacology professor said that monoamine oxidase inhibitors can produce hypotension as an adverse effect, but did not elaborate on the mechanism by which this occurs. I do see that orthostatic hypotension is listed as an adverse effect for Phenelzine and Tranylcypromine on Lexicomp. I checked the Goodman & Gilman text but was unable to find additional information. My only thought is that this occurs through a Clonidine-like mechanism due to activation of alpha-2 auto receptors on presynaptic neurons resulting in a decrease in sympathetic activity. However, this seems to contradict the fact that the goal of these drugs is to increase norepinephrine (as well as serotonin) within the synapse. [link] [comments]  |
| Do Amylase and Bacterial Amylase digest starch the same? Posted: 09 Feb 2019 07:06 PM PST I apologize if this is a stupid question, but it is very important to me. I'm doing an experiment where I digest starch at varying pHs using the enzyme amylase. However, the material available to me is bacterial amylase, which includes high concentrations of alpha‐amylase, ß‐glucanase (gummase), and hemicellulase along with moderate levels of protease. I'm just wondering if the reaction will be any different due to using bacterial amylase. This is for a lab that I'm designing, and I just want to make sure I get it right. I understand that it's the alpha-amylase that digests the starch, I'm just wondering if it would be done in the same way. I couldn't find any answers online, and again, my apologies if this is just stupidity on my end. Thanks for any and all help. I really appreciate it. [link] [comments]  |

| How do dense asteroids and Kuiper Belt objects form, given their relatively small size? Posted: 10 Feb 2019 05:46 AM PST I can't see how metallic or silicate or water "dust" can coalesce under gravity to form dense rocky or metallic or icy objects that are, say, only a few km across. I can picture such material clumping together from dust under its own gravity, but the image I get in my head is just a bunch of tiny particles sort of very loosely "glued" to one another like a cosmic dust bunny. I don't see where there would be enough combined force to fuse the material together into a dense metallic or rocky mass. So should I assume therefore that all small, but dense, rocky or metallic asteroids or comets are chunks of what once had been much larger objects that had sufficient mass to go from "dust" to "solid", but through collisions got broken up into these smaller sizes?

| Are "good" bacteria transmitted between people as well? Posted: 09 Feb 2019 06:22 PM PST I understand there is a risk of pathogenic bacteria spreading to different hosts, but on the flip side, when we are around other people, is there also a chance of "good" bacteria being exchanged?
