- To what extent does one's level of sickness (symptoms, etc...) depend on "pathogen dose" (when exposed to virus, bacteria, etc...?)
- We all know whiskers exist with the function of helping the animal sense their surroundings, but how exactly does it work? And just what does it sense?
- Can two samples of the same size, with the same mean and standard deviation, contain different values?

- Dogs are man’s best friend, but when and how exactly did we domesticate them? What was the process and just how much/excessive/specific breeding did it take to turn the ferocious wolf into the cuddly furry best friends some of us own?
| Why do white arctic animals have black noses? Posted: 10 Aug 2020 07:08 PM PDT If animals in the Arctic have evolved to have all white fur/hair to blend in, why do they still have dark colored noses? For example, polar bears or arctic foxes. [link] [comments]  |

| Has anyone thought of doing this during an earthquake with a drone? Posted: 10 Aug 2020 10:55 PM PDT I always wondered how the earth moves when earthquakes occurred. Most videos on the internet show this with shaky camera footage moving WITH the earthquake. I want to see how the ground moves from a very stable and stationary standpoint. What if scientists programmed a drone to fly upward and immediately start filming after it detects an earthquake? This would show exactly how the ground moves side to side whilst the drone stays completely stationary giving us a very interesting POV. Does anyone know if this has been done? Can it be done?

| Are there any dwarf galaxies between the Via Lactea and Andromeda? Posted: 11 Aug 2020 01:50 AM PDT I know there are many dwarf galaxies out there, but wanted to know if there any directly between our galaxy and Andromeda. If yes, is it fair to assume that they will be consumed by either Andromeda or our own galaxy as they hurl towards each other? [link] [comments]  |
| Posted: 10 Aug 2020 12:37 PM PDT I'm trying to figure out how monatomic powder is made, or if it's even real, but every time I try to look it up it's just a bunch of new wave energy healing stuff. Apparently people sell "monatomic powder," usually gold, some ranging from 14$ to 10,000$ and all of the sellers claim to be alchemists and that it's meant to be ingested for "spiritual healing." Is that even legal to sell metal as food? Lol. Can someone explain what monatomic powder actually is and if it's even possible to make? You'd think it would be easy to google but it's not, the only results that show up are conspiracy related [link] [comments]  |
| Posted: 10 Aug 2020 10:45 AM PDT Is there anything in the skeletal morphology that might give us a hint? I know sauropods may have possessed a respiration system similar to birds and not had as much of a problem as a similarly-proportioned tidal respiration animal, and giraffes have some funky stuff going on but not related to bone morphology. Do we know how would have these non-bird aquatic reptiles would have managed their respiration? Thanks! [link] [comments]  |
| Is there any result related to typical overlaps in orbits of Lie group irreps? Posted: 10 Aug 2020 09:15 AM PDT Hey! So a project I'm working on lead me to the following kinda technical and niche question, I wanted to get any information on where to find an answer if it exists. Suppose G is a compact connected Lie group, and that it acts on some finite dimensional Hilbert space H as a unitary representation. Now let g be sampled from the Haar measure on G. Is there any result stating how large one can expect the random variable |< v, gv >|^2 to be? (Where v is an arbitrary unit vector in H.) When G is the unitary group and H is just the defining representation, this is typically 1/ (dim H)^2 (as in, the distribution is rather concentrated around that mean). I was wondering if a similar result exists, but for different groups and irreps. It's also completely fine if one must impose more regularity conditions on G. Thanks in advance!! [link] [comments]  |
| Posted: 10 Aug 2020 08:28 AM PDT A hybridoma is basically a fusion of a B-cell which produces antibodies and a cancer cell. It's useful for creating monoclonal antibodies (basically, tons of identical antibodies from clones of an original cell). However, it's a labor intensive and expensive process. Given that antibodies are just proteins, why can't we just splice the required genes into a vector (like E. coli), like we do with other lab processes? [link] [comments]  |

| Posted: 10 Aug 2020 10:21 AM PDT In the sense that alcohol intoxication (and possible hangover!) is tied to the amount of alcohol consumed, is there a corresponding concept when dealing with pathogens and infection? Does greater exposure lead to more sickness? Is there ever a "safe level" of exposure, even for very dangerous pathogens (e.g. HIV, Ebola, etc...)? [link] [comments]  |

| Posted: 10 Aug 2020 12:29 PM PDT No right? I feel like the answer is no but something is nagging me about it, and it may be such an obvious question which is why I can't find anything online. I thought I would ask here. [link] [comments]  |
| How do we know how ancient civilizations music looked like ? Posted: 10 Aug 2020 05:43 AM PDT Hello ! I am currently listening "wiking-sounding" music like Wardruna, and I was wondering, we discovered instruments used by ancient civilizations, but how do we know how they used them, and how they sang ? (Thanks for your future responses and sorry for bad english) [link] [comments]  |
| How do bones fuse in the human body? Posted: 10 Aug 2020 07:31 AM PDT I read that babies have 300 bones and some bones fuse and make the 206 [link] [comments]  |

| How does the body know when it's had enough of vitamins? Posted: 10 Aug 2020 07:04 AM PDT I heard that the body doesn't consume all the vitamins that is in it but regulates them,how does the body know when it's full and when it's out of something? [link] [comments]  |
