| How come small cuts on the anus from over wiping or hemorrhoids does not cause serious septicemia? Posted: 21 Apr 2016 01:12 PM PDT Since feces is swarming with many bacteria capable of causing serious infection. [link] [comments]  |
| Do sickle cell anemia and thalassemia interact? Posted: 21 Apr 2016 09:01 PM PDT Sickle cell anemia and thalassemia are similar disorders. Both are caused by genetic mutations that result in malformed hemoglobin. In both cases a single copy of the gene will do little harm and confer a slight advantage against malaria, but two copies will result in serious disease. I'm wondering if a child with one copy of the sickle cell gene and one copy of the thalassemia gene would also be at risk of serious disease. In other words, is it possible for two different but similar recessive genes to behave as if they were paired with copies of themselves? [link] [comments]  |

Are they "hiding" acetaminophen deaths in this figure? Is it a significant percentage? [link] [comments]  |
| Do photons (ie. light) possess the property of inertia, or inertial mass? Posted: 21 Apr 2016 01:22 PM PDT It seems surprisingly difficult to find an authoritative (layperson-friendly) answer to this. It's pretty obvious that a hypothetical box of photons will have a greater inertial mass than an identical-but-empty box, but can light be said to have inertia? [link] [comments]  |

| Why is iridescence usually green and purple? Posted: 21 Apr 2016 01:29 PM PDT I'm thinking of iridescent birds, oil slicks, Mystic paint . . . Green and purple are the prominent colors. Why is this? [link] [comments]  |
| When testing new drugs, does the FDA consider the acceptability of side effects? Posted: 21 Apr 2016 04:50 PM PDT If there was a new drug or procedure that treats sudden and explosive hemorrhage, would extreme kidney or liver damage be acceptable? For a new Alzheimer's drug, would extreme elevated risk of cancer be acceptable? [link] [comments]  |
| What are some of the factors causing an increase in STD rates among gay men since 2013? Posted: 21 Apr 2016 09:49 PM PDT The CDC released some information regarding STDs (see fact sheet and article below), and there was an increase in the rate of infection by 15% between 2013 and 2014 data. This seems statistically significant, but I can't seem to figure out why the large increase. What are typical causes of sudden increases like this? My speculations are that either the ability to be tested, or sampling method have changed, but hopefully someone more familiar with the topic can comment. Thank you very much. [link] [comments]  |
| Is there a correlation between climate change and movement of the tectonic plates?? Posted: 21 Apr 2016 04:28 PM PDT Is there a correlation between climate change and movement of the tectonic plates. We talk about how climate change is going to affect the weather -storms, heat waves, tidal erosion from ocean levels rising. Wouldn't these things affect the tectonic plates?? Loss of ice pack, which reflects some of the energy the Sun throws at us, is shrinking due to warmer water temperatures. This means more of that energy is being absorbed by the oceans, which get warmer, and that brings about more melting. Does the shrinkage of the ice pack affect the tectonic plates?? Does water pressure change with temperatures?? If I am diving, am I under the same pressure at the same depth in hot vs cold water?? I am not a scientist, but I am kinda baked. Any errors in logic and/or anything else should be blamed on sativa. [link] [comments]  |
| Why specifically is Tris buffer problematic with single junction AgCl pH meters? Posted: 21 Apr 2016 11:36 AM PDT Why specifically (what's the chemical reaction?) is Tris buffer problematic with single junction AgCl pH meters? Our double junction pH meter broke and we switched to single junction AgCl meter for a ~month. All my experiments stopped working and I didn't correlate right away cause' everyone elses pH meter stuff worked fine … tried all sorts of unhelpful stuff (getting new polymerase, isolating fresh gDNA, re-making all of my reagents from scratch etc.,). It turns out that Tris buffers form a complex, with silver, that clogs single junction AgCl meters. http://www.bio-rad.com/…/faq/268453677/technical-support-faq Everything's working now, but I'm wondering: what specifically is the precipitation reaction here? I recall that methylamine can form a soluble complex with the Ag of AgCl (is it just that this Tris complex is too big to be soluble?), BUT there are three hydroxyls on Tris that can play too! Anyone know the deets? Google was vague. I don't actually need to know, cause' everything works now … I'm just wondering :D [link] [comments]  |

| Why is the Sin 0i/Sin 0r ratio is equal to the refractive index of a material? Posted: 21 Apr 2016 05:28 PM PDT Hi, I was covering sine's law in my science class and could not figure out how this ratio is equal to the refractive index. Thank you! [link] [comments]  |
| Are nuclear weapons more difficult to develop using fusion technology as opposed to fission? Posted: 21 Apr 2016 02:18 PM PDT Hypothetically, if the world governments somehow successfully prohibited fission technology, would that make fusion developed weapon harder/more expensive to make? I don't understand the relation between the two [link] [comments]  |

| Posted: 21 Apr 2016 10:42 AM PDT I'm having a tough time wrapping my head around how they are made and work. Surely encrypting with both would lead to the same result? From what i understand they can be used as a digital signature, which I quite like the sound of but I just don't quite have enough knowledge to understand. I could only find short videos on it, or hour long lectures (literally a camera sitting in on the lecture). I understand this may not be the usual question this subreddit gets asked but I believe cryptography counts as a science. [link] [comments]  |

| In HPLC systems coupled to electrochemical detectors, what is the guard cell actually doing? Posted: 21 Apr 2016 11:18 AM PDT Also, we have a dual ECD cell system and only use the readout of the 2nd EC cell as our data. Will changing the applied voltage at the first EC cell have any effect on the amount of detectable molecules that I am trying to read with the 2nd EC cell? Likewise, will changing guard cell voltage effect my readouts? I am a neuroscientist measuring neurotransmitters (catecholamines) in mouse brain slices. I really just started getting into HLPC a few months ago and I think I have most of it down, but if you have any questions on the setup let me know. [link] [comments]  |
| How does the brain process images from either side of the head (such as Parrot eyes)? Posted: 21 Apr 2016 09:02 AM PDT I googled the question, (couldn't find much) but it came up with some eye science stuff, with a link to binocular rivalry. I looked into it a little and it said it was when the eyes "alternate between different images presented to each eye". Wouldn't the same sort of thing happen all the time for animals such as rabbits, with eyes on either side of the head? or does this only apply to species with binocular vision.

| Is the temperature of a black hole absolute zero? Posted: 21 Apr 2016 07:17 AM PDT Since matter keeps getting denser and denser, and moves less and less to the point of absolute zero where nothing is moving or vibrating, and it is giving off no black body radiation, would a black hole be absolute zero? It fits the characteristics of what something would be like at absolute zero. [link] [comments]  |
