| Posted: 27 Oct 2016 10:01 PM PDT The bacteria used in cloning already have plasmids from my understanding. And when we insert a genetically altered plasmid, say for insulin production, and we instigate a transformation reaction the bacteria takes in the new plasmid. What happens to their old, original plasmid? It would be odd if they had two distinct plasmids, or at least I would guess it would be inefficient at producing insulin(in this case) [link] [comments]  |

| Posted: 27 Oct 2016 05:40 PM PDT I mean, is there any difference in speech/language developmental milestone (in terms of age at which the milestone is reached) for a baby raised in USA, China or Iraq? Thanks [link] [comments]  |
| Posted: 26 Oct 2016 10:03 PM PDT EDIT: Ok wow lots of responses. Its going to take a while to read through them all but I think the top comments and most others describe it well. It isn't just time, its environmental factors as well. [link] [comments]  |
| How does the wait time paradox work? Posted: 27 Oct 2016 02:15 PM PDT I've read a lot of it on the internet and I found this. If a bus comes every 10 minutes (certain) then you'll on average wait 5 minutes. But if a bus comes on average every 10 minutes (uncertain) then you'll wait on average 10 minutes. How did they calculate the 10 minutes? I tried google scholar but couldnt really find something. Really interested in this because I'm following a statistics class this semester. [link] [comments]  |

| If you boil gelatin, does it break apart/hydrolyze? Posted: 27 Oct 2016 08:42 PM PDT Was wondering if I was to boil gelatin, if it would break down more? [link] [comments]  |

| What are the conditions for animal carcass to fossilize? Posted: 27 Oct 2016 07:21 PM PDT I was reading on r/worldnews and there was a news about a dinosaur brain being found fossilized. I had burried a cat before and after two years, there was no soft tissue left, just bones. does it have to do with being mummified? [link] [comments]  |
| Does Charpy Impact Strength dictate the feasibility of use in ballistic plate carriers? Posted: 27 Oct 2016 06:50 PM PDT I was researching possible alternatives to AR500 for use in plate carriers, mainly because AR500 is a bit heavier than i expected. I noticed that low alloy steel plates, such as AR500, have a Charpy impact of 24 J, while Nylon 12's impact strength is off the charts. I know that nylon isn't used to protect against bullets, since I haven't seen any purely nylon level III ballistic plates, so this is more an inquiry on how one determines the feasibility of a material to replace AR500 in plate carriers.

| Does drinking Gin and Tonic have a strong antimalarial effect? Posted: 27 Oct 2016 11:43 AM PDT Don't know if this is appropriate for this subreddit, so sorry if this doesn't belong here. So I'm going to Mozambique in December (which is a Malaria district) and I was talking to my dad about how expensive the pills were. He told me that he never takes any pills when visits a Malaria district and that drinking Gin and Tonic is the same as taking the pills, witch I obviously didn't trust at first (he's had Malaria 3 times). So I did some googling and it turns out that Tonic water originally existed as a way to deliver quinine, the active ingredient in most antimalarial drugs. So I was basically just wondering how strong the antimalarial effect of tonic water is. Like, could you get enough quinine just drinking Gin and tonic all day without dying of alcohol poisoning? Note: I am not asking for advice, I will be taking my pills. I'm just curious. [link] [comments]  |

| Is there evidence for former mountain ranges? Posted: 27 Oct 2016 06:15 PM PDT Mountains to my knowledge are made by tectonic plate movement against each other. Earth has previously had multiple former continents such as Pangaea or Rodinia, so clearly there was the same type of events that lead to our current mountain ranges. But do we know of any specific extinct mountain ranges? Are there methods of determining such mountains existed besides estimations of them from known former plate activity? [link] [comments]  |

| What causes blackbody radiation to occur? Posted: 27 Oct 2016 08:46 AM PDT So my question is about the processes that are responsible for blackbody radiation at the atomic/molecular level. As in, what kind of transitions are responsible for BB radiation, e.g., vibrational transitions, or rotational transitions etc. Also I am somewhat confused as to the energy levels of vibrational/rotational and translational motion are discrete, whereas BB radiation is continuous. So how can one account for that? [link] [comments]  |
| Posted: 27 Oct 2016 12:56 PM PDT I know that we should be going faster than earth's escape velocity and normal engines don't work because the atmosphere keeps getting thinner till it disappears, But what if we flew at the highest altitude possible by a hypersonic aircraft then we go full vertical and fire a set of rocket boosters, it should get us to space right, along with some fuel savings.

| Would it be possible to code evolution? Posted: 27 Oct 2016 11:38 AM PDT I know we don't have all of the information for the various branches of evolution. But assuming we did, would it be possible to create a base class as some initial prokaryotic organism (maybe even a simple organic compound) with primitive behavioral functions, keep creating sub classes that build upon it iteratively adding more basic functions based on a rough concept of how evolution happened? Coding even a basic Eukaryota organism would be pretty hard, but could building upon it incrementally work to create an organism, as a simulation of evolution? I'm sorry if the question seems poorly thought out, because it is. It's just a thought I had studying software design because inheritance diagrams look extremely similar to the evolutionary tree (which is kind of the point). [link] [comments]  |
| Why are there no Calico humans? Posted: 27 Oct 2016 10:19 AM PDT For reference, perhaps watch this video. It's where the bulk of my knowledge of what 'causes' Calico comes from. https://www.youtube.com/watch?v=BD6h-wDj7bw Hopefully Derek hasn't led us astray on this one. But the question remains, why don't humans show this 'calico' pattern, specifically in children of mixed race? I found this Q/A with a couple of scientists, but both of them seem to have just gone with "well we really don't know" http://www.thenakedscientists.com/HTML/questions/qotw/question/1000075/ Surely there must be a better answer out there. I know about Chimerism, but that's not the same thing, and still doesn't show physically (except on episodes of CSI) Thanks! [link] [comments]  |
| How are extremely rare minerals found underground? Posted: 27 Oct 2016 11:55 AM PDT I was reading around on extremely rare minerals like Painite. Where only 2 crystals of it have been found ever. It got me wondering, how do people find stuff like this? I'm assuming stuff like this is just found by accident. When Miners are digging away with their machines, do they have to check for really rare minerals or is it found later down the line at processing? [link] [comments]  |
