| Posted: 08 May 2020 07:44 AM PDT I'm a materials scientist, so from a crystallographic point of view I'd imagine the sugar, when exposed to air, crystalizes in such a way that locks and prevents movement between sugar grains. If this is true, why would the crystals form when exposed to air from a scientific perspective? Additionally, what function does putting a slice of bread inside hardened brown sugar serve? Does it absorb moisture thus allowing sugar crystal movement again? [link] [comments]  |
| Posted: 07 May 2020 05:41 PM PDT To be clear, I'm not anti-vaccination. I'm very much pro. But if the idea behind a vaccine is that the antibodies will provide immunity, but that we don't have evidence that these antibodies are doing that, then why are we so confident a vaccine is the answer?

| Why high end audio equipment tend to have higher impedance? Posted: 07 May 2020 11:58 PM PDT I just got myself a Shure SM58 as a mic which has an impedance of 300 Ohms compared to the 150 of my previous, lower end microphone. Same goes with headphones with some high end models going in the range of 200/300 Ohms while common earbuds sit at around 30 Ohms. The basic principle across all of those devices is the same, being magnetic induction so why higher impedance is preferred for good audio quality? Does the fact that by increasing resistance the inductance (which complex impedance varies with frequency) is less important so the response at the various frequencies is more constant? I'm a physics undergrad so you can go pretty deep with technical explanation if you want, I hope to be able to understand it. [link] [comments]  |
| Posted: 08 May 2020 12:38 AM PDT So there's some hope of giving blood plasma from COVID19 recoverers to those that are infected and high risk of death. Would donor and recipient of the plasma have to be of the same blood type? Or does the separation process remove that requirement? [link] [comments]  |
| How does the coronavirus/COVID19 test detect the presence of the virus? Posted: 08 May 2020 08:15 AM PDT I tagged chemistry because I guess it would be to do with that? To elaborate, what is actually done with the sample to find the virus? Is it like just put in a computer and it detects... something? Or do you put the sample in a solution and then it goes purple for positive and a bluer purple for negative? I'm just curious about the process and how it works after the initial swab that we see from the side of being tested. Hope this doesn't violate any rules, and isn't too broad a question, and I'm sorry if the flair's wrong. [link] [comments]  |
| Posted: 08 May 2020 04:57 AM PDT I was thinking, just like how legal marijuana was unfathomable a decade ago but thanks to individual states trying it out it's now slowly spreading across the country. Why can't the same be done with single payer healthcare? Isn't that why states have these rights? So they can act as testing grounds for ideas? Thanks [link] [comments]  |

| Why are some scars permanent? Why do they last longer than your other skin cells? Posted: 07 May 2020 03:30 PM PDT Why don't scars just slough off over time like your skin? What about them makes them more permanent? [link] [comments]  |
| Why is the moon covered in so many craters but the Earth isnt? Posted: 07 May 2020 02:26 PM PDT Why does the Earth have seemingly so few large craters unlike the moon? Weren't they created at the same time? And technically, since the moon is smaller shouldn't it have a lesser chance of being hit? Or were the craters on the moon not created my meteorites?

| Do animals feign death intentionally or is it uncontrollable reflex from a threat? Posted: 07 May 2020 04:48 PM PDT I saw a popular and funny video of a snake faking death by turning upside down. When the person with camera turn it back over it continuously turn back upside down over and over. It seemed like the snake could have quickly scurried into bushes to get away, but it's just kept turn upside down over and over again. Can animals control this behavior or is it a reflex that they can't control? [link] [comments]  |
| How does algae cells assimilate phosphorus? Posted: 07 May 2020 05:39 PM PDT I was wondering how plant cells take in phosphorus. For an example when phosphorus from fertilizer gets into a nearby lake. Then the algae take in the nutrients, and can create blooms of algae. How exactly does the the phosphorus get into the cell through the cell membrane. I have tried to find pictures, but I can't seem to find any. Thank you in advance! [link] [comments]  |

| How are tectonic plates mapped? Posted: 07 May 2020 12:59 PM PDT I was just reading this post about volcanoes and it got me thinking- how do we know where the boundaries of the tectonic plates are? How precisely can we know the boundaries? [link] [comments]  |

| What makes different parts of the brain carry out functions? Posted: 07 May 2020 05:15 PM PDT I have been searching on the internet but can't seem to find any explanation to why distinct areas from the brain ,like lobes for instance, carry out tasks that don't have anything to do with each other if they are all made up by the same nervous tissue. Are chemical receptors the key to what each area is responsible for, is it the architecture, or is it something else? [link] [comments]  |
