| How do testing results for viral diseases get false positives? Posted: 11 Jul 2020 06:34 AM PDT This question came about because of COVID19 of course, but I've always wondered how tests can receive false positives for something that isn't even in the body. I'm guessing it could be other viruses triggering the tests, but I'd love to know more about it. [link] [comments]  |
| Does the chicken pox vaccine, varicella, prevent herpes (cold sores) outbreaks? Posted: 11 Jul 2020 02:49 AM PDT As a sufferer of cold sores, is this a possible solution to reducing/stopping outbreaks? [link] [comments]  |
| Do protons and neutrons touch each other within the nucleus an atom? Posted: 10 Jul 2020 04:13 PM PDT We've all seen the models of atoms which show a pile of protons and neutrons, making of the nucleus. Is this model accurate? More specifically, is there a measurable distance between the individual protons and neutrons, or are they "touching" in the way people normally use the word? [link] [comments]  |

| Does infection testing use bisection search? Posted: 10 Jul 2020 03:13 PM PDT Is it feasable to pool drops of samples and bisect in the hope that one half will test negative, halfing the search space in one fell swoop? There's two sides to the question. I know that, mathematically, binary search is optimal under certain conditions, but I'm not sure the conditions are met in this context. I don't know at all if pooling samples is in any way feasable. I heard reparts meassuring about the time for a single test (taking far too long), implying only single tests are run, unless the number was amortized. [link] [comments]  |

| Are there any fuel/oxidizer combos which rapidly decompress or implode when burned? Posted: 09 Jul 2020 11:05 PM PDT I know when most things burn they release gas and if contained some can explode. I'm wondering if anything does the opposite. [link] [comments]  |
| Is there a sociological minded approach to maximizing the tips placed in a tip jar? Posted: 09 Jul 2020 09:47 PM PDT I work at a takeout counter and my coworkers all have different approaches they say get the most tips, from trying to keep the jar empty, to making sure there's always only a few dollars in it, to leaving a $5 or $10 in there to entice others to give more. I figure there's got to have been some serious study or at least a couple published experiments on stuff like this, but I don't feel like I have the context or background on the field to work them into a proper approach.

| What makes certain geographic locations that are far away from each other similar in climate? Posted: 09 Jul 2020 10:18 PM PDT I have noticed that certain locations (for example, the coast of Chile and the coast of California, longitude-wise, or the American Northeast and Germany, latitude-wise) seem to have similar climates, even though they are far away from each other. What factors contribute to this phenomenon? [link] [comments]  |
| Do animal communities learn fear of humans? Posted: 09 Jul 2020 10:55 PM PDT I have heard about animals on the Galapagos being not fearful of humans bec they had not seen any or been exposed to violence. Now there are reports of animals who have been left alone w humans all quarantining walking about towns and supermarkets into open doors at houses, all of them seemingly less fearful of humans. What is this phenomenon? Is it an actual thing and how does it develop? How can animals learn fear of humans if upon experiencing say a hunter the organism dies and can not contribute adaptation towards that experience or pass it on? Isn't a longer period of time necessary for the change in behavior of many animals? It also seems that it's the whole community of animals sharing this learning? Is that possible? And can it be btw different species communities? Has that ever happened? I need an animal behaviorist to explain, . Ty. [link] [comments]  |
