| Why do illness symptoms vary in intensity by time of day? Posted: 09 Aug 2016 06:38 AM PDT I'm suffering through a case of strep throat at the moment, and every day is the same pattern. I wake up feeling terrible, then for the next few hours it quickly improves to the point where I feel pretty good in the middle of the day. Then around 2 - 3 PM my throat and head start to hurt more, and by bedtime I'm in a lot of pain again. What's changing in my body to vary the amount of pain I'm feeling? [link] [comments]  |
| How is MRI scanning used to accurately determine age? Posted: 09 Aug 2016 02:52 AM PDT I saw the post about the majority of the U17 Nigerian football team being banned because they failed MRI tests. How can a scan determine age so accurately when adolescents enter puberty at different times and grow at different rates? [link] [comments]  |
| Posted: 09 Aug 2016 12:32 AM PDT The question im dealing with is; A charge Q is in an Electric field E that is directed vertically upward what is the work done by the electric force when the charge is moved X meters to the right. What i understand is that i need to find Force to find work (w=fx) and i need to find force using F=EQ However, because the direction of motion of the charge is to the right, and the field is vertically upward does this formula still work? or is the answer zero? im unsure. Also, first time submitting here, not sure if this is the correct place to do so [link] [comments]  |
| Posted: 08 Aug 2016 04:11 PM PDT I assume that radiation getting thru unshielded materials is the equivalent of this for non-visible light. If not, why not? [link] [comments]  |

| Posted: 08 Aug 2016 11:00 AM PDT I've read that proton decay is handled by x and y bosons, but I don't get how. They have color charge and weak isospin so I assume they act on a single quark, bu what happens to the other quarks, and why can the x and y decay into two quarks despite only having one color charge?

| Why do we feel mosquito bites? Posted: 08 Aug 2016 02:01 PM PDT Why do we feel mosquito bites? It is not a sting, but it itches. Is there some evolutionary "rationale"*? Or is it just a random side effect of some sort? *Don't worry, I am aware evolution is arational. [link] [comments]  |
| Posted: 08 Aug 2016 09:09 AM PDT Big Bang graphics explain what happened at what time very precisely. At what speed or under what gravitational forces are those time measurement supposed to be made? [link] [comments]  |
| What is the 'bump' at rotation of a commercial airplane? Posted: 08 Aug 2016 11:52 AM PDT At rotation (when an airliner's nose first rises up, during takeoff), there is usually a noticeable 'thump' or 'bump', in terms of both sound and physical sensation. Given that the plane is becoming airborne at that point (i.e., applying increasingly less weight on the wheels and ground), what causes this 'bump'? [link] [comments]  |
| Why are the polar ice caps melting at different rates? Posted: 08 Aug 2016 01:50 PM PDT As I understand it, the arctic ice caps are in pretty bad shape, but the antarctic sea ice actually posted a record max extent. Not sure how to explain this one to a climate change denier friend of mine. I haven't been able to find an answer that was very definitive or particularly satisfying. The article sites the shape of the earth, terrain, and weather (particularly wind) as potential factors, but I didn't get the sense that we have a concrete understanding.

| Posted: 08 Aug 2016 10:55 AM PDT I know I can get an interval between two integers in the graphic, with the function f(x) = x! and obtain the corresponding value to "x" which in this case would be decimal. But what it really means that value? (conceptually). [link] [comments]  |

| How does a PET Scan locate the tumor(s)? Posted: 08 Aug 2016 01:36 PM PDT My father had cancer a few years ago and he had to have a PET Scan. They injected the radioactive material into him and he had to sit still for 8 or so hours. When it was over the doctors knew where and how big the tumor was. Basically I want to understand how the scan locates tumors. Why does the material go to the tumor? Also, is the reason the patient can't move because the material would conglomerate to the muscles used to move if they did? [link] [comments]  |

| Can the GMO mosquitoes transmit something to humans? Posted: 08 Aug 2016 01:29 PM PDT In the wake of Zika, Florida is considering releasing GMO mosquitoes to mate with native mosquitoes and produce sterile offspring in order to reduce the population. People are wary though. I reasoned that there's no way that the released mosquitoes could be an issue for humans because they are male and only females bite humans. But then, females only bite to nourish their babies when they are pregnant by said males. Could the modified mosquitoes transmit something to their mate which in turn is transmitted to the human they bite? [link] [comments]  |
