| What makes a virus more transmissible? Posted: 19 Dec 2020 06:52 PM PST The 'new' strain in the UK is being said to be 70% more transmissible. My understanding is that Covid spreads primarily through exhaled droplets. Could the new strain cause a higher viral load or make it hang in the air longer? [link] [comments]  |
| How much salt can be in water before its unsafe to drink regularly (like sea water)? Posted: 19 Dec 2020 10:24 AM PST Also, is it just the sheer amount of sodium chloride that makes sea water dangerous or is there other things in it in large amounts that contribute to it being harmful?

| How common is covid-19 reinfection? Are there any published statistics? Posted: 20 Dec 2020 05:27 AM PST The covid epidemic is in full swing in Europe and the USA, and we've had extensive testing for more than a few months. I know there are individual reports of reinfections, but are there any published statistics on the number of reinfections? [link] [comments]  |
| When should a person who has had covid and recovered get a vaccine? Posted: 20 Dec 2020 04:41 AM PST Since I had it 3 months ago and I have tested negative since then my gut instinct tells me I should be one of the last to get the vaccine. I am not in an "at risk" group. I'm 43, healthy (excluding epilepsy) and judging from actual calculated odds from medical journals articles I have a 3 times greater chance of being eaten by a shark than to be reinfected. Should I even worry about getting the vaccine? Can I rely on my already built immunities? I know it wouldn't harm me to get the vaccine, but that shot could go to someone else who is at risk or has a compromised immune system [link] [comments]  |
| How much radiation did the Demon Core put out when not shielded with Beryllium? Posted: 19 Dec 2020 12:04 PM PST Louis Sloten received around 1,000 rads of radiation when the screwdriver slipped on the top beryllium sphere causing the core to go prompt critical. I am having a hard time finding information about how much radiation the core was putting out by itself when neutrons were not being reflected back into the core. Scientists were apparently handling the core often so my guess is that it wasn't that lethal by itself but I can't find any documentation on how much radiation the core put out normally.

| Posted: 19 Dec 2020 03:59 PM PST I am seeing an increasingly large number of social media posts and press articles claiming Vitamin D can protect people from COVID-19's most serious effects. Some of these posts imply there is a conspiracy to inhibit the dissemination of this information because "big pharma" can't make money on Vitamin D supplements. So... is there currently a consensus?

| Are the antibodies created by the immune system different for each strain of a virus? Posted: 20 Dec 2020 02:44 AM PST As I understand the the immune system identifies an antigen through the proteins from the DNA/RNA of a virus. I also understand that there are multiple strains of the same virus. Moreover there are reports that some people who have recovered from Covid-19 were once again infected by it Broader questions that I have for the community: 1. Does the immune system create a single antigen that can fight again all the strains of the same virus? 2. Are the antigens created by different people different from one another? 3. Taking both 1 and 2, would we be better able to understand how effective convalescent plasma therapy has been? 4. Are there any chances that an immune system can assume that a foreign antigen is an anti body and attack it as well? With my limited knowledge I am assuming that some antibodies can fight multiple strains of a virus but not all the strains. And inferring from that I am assuming that convalescent plasma Therapy may be more effective only when the right antigens are fighting the right antibodies. But I would prefer the community helps me understand these questions better. [link] [comments]  |
| How is a mRNA vaccine, such as for COVID-19, mass produced? Posted: 20 Dec 2020 02:35 AM PST What are the steps for mass producing a mRNA vaccine? I am not sure if there are other vaccines that are based on mRNA other than COVID-19. [link] [comments]  |
| Does the more virulent covid strain mean that prior herd immunity estimates are not accurate? Posted: 19 Dec 2020 10:53 PM PST Number for herd immunity is 1 minus the inverse of Ro. I've read that the new strain is about 70 percent more infectious. I assume this means the Ro is about 4.25. Does this mean that if this strain becomes prevalent, we will need about 77 percent of people immunized before herd immunity instead of 60 percent? [link] [comments]  |
| Posted: 20 Dec 2020 03:49 AM PST My grandparents (80 & 83) have already had covid19 back in april/May. Because we presume they have some immunity, we visit them, but still stay at a distance, don't hug, desinfect our hands, only 2 visitors per day and all the precautions. There has been found a more transmissible strain of the virus, but I can't find anywhere if it is different enough for people to get sick of it again. Are there any results/information about that yet? I'm afraid that because it is more transmissible, I or my family can infect my grandparents. [link] [comments]  |
| Why can't we just use hydrogen combustion engines? Posted: 19 Dec 2020 05:55 PM PST Like, the engine itself would probably have to be drastically reengineered, but hydrogen is an especially powerful fuel, hence why its used in rocket fuel. And it only produces water vapor, so it would play a hig part in reducing emissions. [link] [comments]  |

| Where does the mRNA in mRNA vaccines come from and how does it differ from the virus? Posted: 19 Dec 2020 10:26 PM PST Where does the mRNA used to create the specific proteins one wants to create come from and in what sense can it be equated to a portion of the virus responsible for the production of the specified proteins? I other words, how wrong is it to say: The mRNA from an mRNA vaccine is contained in the RNA virus? [link] [comments]  |

| Posted: 19 Dec 2020 04:16 PM PST [kind of similar to how microplastics accumulate in human tissue - the long-chain tannins and waxes might have some structural similarities to microplastics] [link] [comments]  |
| What makes an infectious disease infectious? Posted: 20 Dec 2020 01:10 AM PST Does the pathogen reproduce a lot more within the body making it spread easier between contact or is it the symptoms they cause like coughing and sneezing that make it infectious [link] [comments]  |
| Are we humans immune to past pandemics? Posted: 19 Dec 2020 07:41 AM PST If someone someday decided to travel back in time would they be immune to the viruses/diseases of that time. [link] [comments]  |
| Did insect "hair" evolve independently from mammal hair? Posted: 19 Dec 2020 10:02 AM PST Or can we tell? Do they look like they evolved from some common innovation before our branch split from insects or are they as different as e.g. human eyes vs insect eyes? [link] [comments]  |
