| If a recently deceased human corpse is placed in the sun will it get sun burned? Posted: 19 Aug 2021 02:47 PM PDT And if so when is the average cutoff time where the process of skin becoming sunburned will cease to take place? Edit: since there seems to be a lot of confusion not physically inside the sun but on earth in direct sunlight. [link] [comments]  |
| Why do teenagers need the covid-19 vaccine? Posted: 20 Aug 2021 03:55 AM PDT Okay, hear me out and I'm sorry if wrong sub. Mom is anti-vax so all I get is it will shorten life expectancy. I've received a letter saying I can book my vaccine, I am eager to, however, it doesn't stop transmission and my mum says as a teenager I would not be ill with covid? I will probably still get the vaccine, but why is england mandating that teenagers get it? My government has also said herd immunity cannot be reached? I AM NOT ANTI VAX- I just would like this cleared up. I still want to get my vaccine because it makes life easier for me/others. Thank you for an award! Thought I'd add this I can't find the comment saying england isn't mandating for teenagers, sorry let me clear it up this is my fault. Yes it's being offered, however certain things are becoming (in September I believe) where you can't enter/go if you aren't vaccinated isn't that the rules, if I am wrong I apologise, I should have explained that properly. I don't want to be unable to do things as I'm not vaccinated. My bad that is me being misinformed ! Also, unsure if anyone cares, spoken to my dad, getting vaccinated next week. Thankyou for all the comments :) [link] [comments]  |
| Does anything have the opposite effect on vocal cords that helium does? Posted: 20 Aug 2021 07:30 AM PDT I don't know the science directly on how helium causes our voice to emit higher tones, however I was just curious if there was something that created the opposite effect, by resulting in our vocal cords emitting the lower tones.

| Posted: 20 Aug 2021 04:27 AM PDT Long story short, I found myself in on the cusp of an argument with someone over getting the seasonal flu shot. I mentioned I wanted to get a flu jab to help avoid the risk of potentially giving my mother, who is receiving chemotherapy, the seasonal flu. The other person said I was more likely to transmit the flu if vaccinated, as the vaccine would make me an asymptomatic spreader. Is there any basis to this argument? [link] [comments]  |

| What makes one type or species of wood harder than another? Posted: 19 Aug 2021 06:33 PM PDT On a cellular level, why are woods like oak, rock maple etc. so much harder than others like pine or cedar? Is it a different amount of lignin, or smaller cells packed tighter together? Do softer woods have thinner cell walls or weaker connections between the cells? [link] [comments]  |
| If you are allergic to one vaccine are you likely allergic to all vaccines? Posted: 20 Aug 2021 04:29 AM PDT If I understand, there is a one on 760,000 chance someone will be allergic to the Covid 19 vaccine, which is why they ask you to wait. The CDC website also states if you have a severe reaction to the first shot, you shouldn't receive another. My question is, if someone had previously had a severe allergic reaction to a different vaccine, would their doctor recommend skipping all further vaccination, or just that vaccine in the future? What makes someone allergic to a vaccine, and if you were vaccinated with any in the passed and DIDN'T ever previously have a reaction, does that change the 760,000 to one odds in any way?

| Posted: 19 Aug 2021 09:59 PM PDT Watching the season finale of Alone and I always wonder about the common strategy of rationing food. If you have, say, ~5000 calories at your disposal, are you better off eating 1700 calories worth of meals for 3 days, then fasting for 4 days, or eating 700 calories worth of meals every day for 7 days, or 350 calories a day for 14 days, or does it not really matter - it's net calories that matter?

| Is most melatonin produced synthetically? Posted: 20 Aug 2021 03:19 AM PDT tldr: Are we still prying melatonin out of mammalian pineal glands and placing it in supplements or has this practice effectively ended? I think the risks associated with doing this are substantial, but there is poor oversight in some jurisdictions where melatonin is OTC, and I'm not sure what to believe about this. Melatonin is found in a bunch of places: certain plants contain it, it can be synthesized from tryptophan, and of course it is contained in the pineal glands of mammals. Apparently, some melatonin supplements are derived from the pineal glands of cattle. This is worrisome, there are all kinds of risks associated with consuming this kind of thing and among those risks is CJD, the most common prion disease in humans. What I would like to know is whether this is still a common practice, and if not, when exactly did we stop doing this? All I can find on this topic is a few vague statements in various places along the lines of "most melatonin is synthetic now," but this doesn't seem convincing to me. Adding to my skepticism is the fact that the quality among OTC melatonin supplements has been demonstrated to be terrible, with huge inconsistencies between stated dosages and actual dosages contained within the pills. I would not be surprised if all of the OTC melatonin continues to be produced in this very risky way given the very poor quality control. A convincing counterargument would be that synthetic melatonin is cheaper to produce than the animal-derived kind, but I have no way of estimating the margins either way here. HGH derived from cattle brains has caused CJD in children who were administered it. This is a very real risk with melatonin as well if it is still being produced non-synthetically, hence my question. I'm not really sure that this question has a definitive answer, nobody can speak for every single supplement out there, so I suppose I'm asking more about the likelihood that this practice is widespread.

| Why are (human) atriums and ventricles separated? Posted: 20 Aug 2021 02:19 AM PDT I understand that a fish's two chambered heart is less efficient because oxygenated and deoxygenated blood mix, but in a human heart the left and right side pump blood in two independent systems. So why does our heart have four chambers and not just two left and right chambers? [link] [comments]  |

| Why is Bismuth naturally Diamagnetic? Posted: 20 Aug 2021 03:53 AM PDT I know many elements are ferromagnetic like Iron, but how is Bismuth naturally Diamagnetic? Is it only diamagnetic as an ingot, or are it's crystals naturally diamagnetic as well? [link] [comments]  |
