| Which planet is the most visible from another planet in our solar system? Posted: 14 Oct 2019 12:30 AM PDT I personally believe it would be Venus from Earth, but I think other possibilities would be Venus from Mercury and Jupiter from Mars . Is there someone who has the data or who can do the math? I suspect having a planet fully "behind you" reflecting all of the suns light could mean that looking outward(Mercury to Venus, Venus to Earth or Mars to Jupiter) would make that arrangement much brighter "when the planets align" [link] [comments]  |
| Posted: 13 Oct 2019 11:37 AM PDT Why does that happen? Their body is dying, so what's the deal with suddenly feeling better. Is it similar to how your body goes into shock to keep you from feeling pain? [link] [comments]  |
| Why is the Pacific Ocean split in temperature? Posted: 14 Oct 2019 02:42 AM PDT Why is it that on the California coast, the Pacific Ocean is so cold, yet when you go to Hawaii, the ocean temperature warms up much more? [link] [comments]  |
| Why don't the slits in a dual slit experiment cause decoherence in the wave function? Posted: 14 Oct 2019 07:41 AM PDT In the dual slit experiment the wave form collapse occurs on measurement at the detector screen. The screen is a macroscopic element, and this make some sense. However, the light also interacted with the screen, which is also a macroscopic element. Why did this not cause collapse as well? It is due to not being entangled with the screen?

| Are camera CMOS sensors sensitive to beta radiation? Posted: 13 Oct 2019 05:06 PM PDT Specifically, I have a MILC and a piece of depleted uranium. Could the camera pick up on its beta radiation? [link] [comments]  |
| How do strong acids "eat through" things? Posted: 13 Oct 2019 02:41 PM PDT Just wondering what the chemistry is here. I know that acids are compounds that either donate protons or accepts electrons, but I'm not sure how that results in the effect of eating through stuff. Why is it almost a universal effect for strong acids to eat through things? Can bases do the same thing, and if so how do they do it? [link] [comments]  |
| Posted: 13 Oct 2019 12:30 PM PDT If a patient builds up a considerable tolerance to a prescribed stimulant (i.e. Vyvanse) then stops the drug, and restarts it years later, can there be evidence of residual tolerance left over from that initial experience? What would be the mechanism? I've heard of the notion of receptor "down-regulation" being thrown around casually, but its hard to find anything evidence-based. Essentially I'm asking, does tolerance completely go away/reset, or does some aspect of it stick around, and if so, how? In this paper, there's some discussion of the mechanism of tolerance and "up-regulation of adenosine receptors" in caffeine tolerance as a comparative mechanism but it still doesn't directly address the question or phenomenon.

| What role does serotonin play in IBS-C vs IBS-D? Posted: 13 Oct 2019 12:37 PM PDT I was reading this article on serotonin's significant role in IBS. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4266036/ So from my understanding it is saying IBS is caused by an excess of inflammatory cytokines which stimulates the IDO enzymes which mess with conversion of tryptophan to 5-htp and serotonin by creating kynurenine instead of serotonin. This causes a serotonin deficiency. Since serotonin is important for gut motility this deficiency is the cause of IBS. Question 1: Am I understanding the article correctly? Question 2: But this all seems to relate to IBS-C where gut motility is too slow. Does this mean IBS-D, gut motility which is too fast, is caused by an excess of serotonin? If so through what process is the body making too much serotonin? [link] [comments]  |

| Do larger animals have a bigger chance to get cancer? Posted: 13 Oct 2019 09:18 AM PDT Larger animals have more cells, and since cancer is a defect cell, more cells should mean a higher chance at cancer, right? [link] [comments]  |

| How Do Inward-Rectifying Calcium Channels INCREASE "Resting" Potential In Pacemaker Cells? Posted: 13 Oct 2019 11:46 AM PDT I understand that less inward-rectifying Ca2+ channels is responsible for the higher mV "resting" potential of pacemaker cells (and consequently keeps the fast Na+ Channels inactive), but how does that make sense? The inward-rectifying Ca2+ channels are responsible for uptake INTO the cells. By having less of them, would it not mean that there are less positive Ca2+ ions going into the cell, thus the charge would be MORE negative? Additionally, as a bonus question, would the decrease in intracellular calcium due to less of these channels affect the rate /force of contraction, given the need for Ca2+ to release calcium from the SR via CICR?

| Why does the length of twilight differ according to latitude? Posted: 13 Oct 2019 07:52 AM PDT I have observed how day changes to night much more quickly at the equator than at home around 50°N. Do the seasons also change twilight's length here? [link] [comments]  |

| What, besides the ship skin, protects cosmonauts from solar radiation during the long stay in space? Posted: 13 Oct 2019 06:34 AM PDT If I'm not mistaken, solar radiation is able to almost fully pass through the ship skin and deal damage to cosmonauts' health. So, how can people be protected from it during for example the flight to Mars which will last for about 8 months? [link] [comments]  |
