| Posted: 21 Aug 2021 10:44 AM PDT Obviously it's best to be careful about these things. That said, with this new form of vaccination, a lot of the uncertainty of 'old school' vaccines is out of the picture, right? Supposing the method of getting mRNA into the body remains the same, and the proteins produced are innocuous – is there still reason to think that there could be unforeseen side effects?

| Does organic matter decompose in highly irradiated zones? Posted: 21 Aug 2021 08:23 AM PDT So I have read in the past that the most irradiated areas of Chernobyl are at high risk of wild Fire due to the abundance of deadwood that accumulates because bacteria aren't able to successfully colonize the area enough to initiate decomposition due to the radiation. So this question came to my mind, it might sound a bit obvious or silly but does this mean that all organic matter is unable to be decomposed or does wood resist the hindered bacteria because it's more resistant to decomposition than flesh? Is the radiation in the high-risk zones high enough to kill all bacteria or enough that it renders all processes of organic decomposition impossible or not? If, for the sake of experimentation, I were to put a chunk of meat in a highly irradiated zone and leave it there for decomposition to take its course would I find it still unaltered as if I had sterilized it using irradiation?

| How significant are asymptomatic COVID-19 infections to the transmission of the disease? Posted: 21 Aug 2021 04:27 PM PDT I know vaccines like Pfizer were shown in clinical trials to be quite effective at preventing symptomatic infections. What about asymptomatic infections, though? How big of a deal are they at this time, esp. with the rise of the Delta variant accompanied by waning vaccine effectiveness? [link] [comments]  |
| How do we know that the neutrinos have spin? Posted: 21 Aug 2021 11:41 AM PDT Neutrinos are neutrally charged particles that do not interact neither by strong force or electromagnetism. How do we know that neutrinos are spin 1/2 fermions? Could neutrinos have higher spin numbers? [link] [comments]  |
| Posted: 22 Aug 2021 04:55 AM PDT I know the flu mutates quite rapidly, hence why the vaccine needs to be updated, but presumably the strains in 2 successive years are more similar to each other than 2 strains 10 years apart. Does that mean that having had the flu in a given year provides some protection the next year (even though a different vaccine will have been made)? Edit: This question has arisen because there have been headlines saying this year will be a very bad flu season in areas that have had lockdowns over the last 18 months as flu rates were so low during that time.

| Why do water bottles act differently in my fridge? Posted: 21 Aug 2021 09:10 PM PDT Hi all I'm curious about something. My fridge is a basic one. Big fridge compartment and a small freezer one. Inside the fridge compartment there are the standard 2 drawers for storing vegetables. The one difference is that the fridge allows me to set a separate temperature for one of those drawers. The fridge itself is at 4 degrees Celsius and I've set that compartment to -4 degrees. Am using it for drinks storage Mostly I'm washing and reusing glass coke bottles (both the 300 and 385ml varieties, have about a dozen or so of each #CokeFiend) as water bottles. It's super convenient to just reach into the fridge and grab an ice cold bottle of water, especially when I have guests over. Now I know from high school the melting point of water is 0 degrees, so at -4 I'd expect my drinks to be frozen solid. In fact when I first discovered that I could change the temperature I kept reducing it gradually at first until I was sure the drinks in there wouldn't freeze (also had some soft drinks and beers in there and didn't want the bottles to explode). So when I got all the way down to -4 and they were still drinkable I was surprised. Sometimes my soft drinks freeze a little and develop a slushy like texture but I'm totally not complaining, I love that) However what's confusing me is this. Some of the water bottles freeze amd others don't. I'd say maybe one in every 10 bottles will freeze. I've done some experiments over time and nothing makes a difference. Doesn't matter if it's a 300ml or 385. Doesn't matter if there's many bottles or few. Doesn't matter where I put the bottle in the compartment, left/right/middle or on top of or beneath other bottles. The freezing seems to be random and I'm really curious what's causing certain bottles to freeze and not others Also, side question. Occasionally the frozen bottles burst. My theory is I'm simply overfilling them occasionally and the ice has no room to expand. Can anyone confirm/deny this? [link] [comments]  |

| Posted: 21 Aug 2021 11:37 AM PDT How does that "memory" work? This comes from a friend asking whether the protection from a COVID-19 vaccine would be diluted somehow by a blood transfusion from an unvaccinated person. [link] [comments]  |
| Posted: 21 Aug 2021 04:05 PM PDT Health agencies have seen a slightly elevated rate of myocarditis after vaccination with mRNA vaccines particularly in young adults mainly between 18-24. It should be noted that despite this, the risk of myocarditis after an mRNA vaccine is far lower than the risk of myocarditis after COVID-19. However, I'm curious, have we seen higher than normal incidence of myocarditis after vaccination with an Adenovirus vector vaccine, such as the J&J, AstraZeneca, and Sputnik-V vaccines? If not, why not? If this myocarditis risk was due to immune response, would it not affect Adenovirus vector vaccines as well? Both vaccines encode for the spike protein and have the dendritic cells produce these antigens. AFAIK the only difference between Adenovirus vector and mRNA vaccines is the delivery method. Adenovirus vector vaccines deliver spike protein encoding via DNA by infecting cells. mRNA vaccines have a lipid nanoparticles that shuttles the mRNA into cells. But after delivery, procedures are the same no? [link] [comments]  |
| What actually kills a plague victim? Posted: 21 Aug 2021 09:22 AM PDT Is it something the bacteria do to the body, or is it sepsis that kills plague victims? [link] [comments]  |
| Is Covid more infectious than a common cold? Posted: 21 Aug 2021 08:09 PM PDT Not sure if this is quantifiable, but just curious. I've seen lots of things comparing it to the flu and saying it's more infectious than that, but I've only ever had 2-3 flus in my life, i've had dozens of colds though. Curious if it's quantifiable. Thanks [link] [comments]  |

| What do telescopes actually record/capture? Posted: 21 Aug 2021 05:55 PM PDT I was watching the documentary on Netflix about Event Horizon Telescope and they had three teams working on processing data to generate an image of black hole. What data are they actually working on? What information does a telescope output? I always thought telescopes captured light and gave out images just like cameras do. But now I do not think that is true. [link] [comments]  |
| Does the Bering strait ever freezes enough so that somebody could cross it by car? Posted: 21 Aug 2021 04:20 AM PDT I have heard some people tried it before, is it actually possible to drive from America to Russia via the Bering strait? [link] [comments]  |
| Do lights hurt deep ocean entities? Posted: 21 Aug 2021 02:43 AM PDT Do scientists that do deep sea/ocean exploration know that the videos and pictures they take of deep sea/ocean creatures won't blind them? It's been a question of mine for a long time. These animals are used to a dark environment and they may see in different light spectrums than we do. So do scientists take that into consideration when they film them? [link] [comments]  |
| How does sand form from rocks on planets without atmosphere? Posted: 21 Aug 2021 08:25 AM PDT I'm thinking about very fine grained sand in significant quantities on planets that do not have an atmosphere. The question could extend to dust as well. [link] [comments]  |
