- Studies from 2003 in China, showed that 80% of the wild animals in the markets and 13-60% of traders with wild animals had SARS-Cov-1 antibodies indicating of larger spreading of the virus. Do we have similar early studies for SARS-Cov-2?

I can't find such studies for SARS-COV-2. Are there any? [link] [comments]  |
| Why is gravity stronger in the ocean than on land? Posted: 26 Aug 2021 03:50 AM PDT This gravitational anomaly map shows that all of the oceans have more gravity than all of land. Is this because land is more elevated? Water is less dense than rock, so I would have assumed it would be the other way around. [link] [comments]  |
| Does the moon, other planets experience earthquake? Posted: 25 Aug 2021 10:35 PM PDT Someone asked a question in r/moon whether there are earthquakes on the moon and it made me wonder do other planets (it's moons also?) experience earthquakes? [link] [comments]  |
| Does antibody response adapt with exposure to different Covid strains? Posted: 26 Aug 2021 05:52 AM PDT If you recieved a Covid-19 vaccine, the vaccine generated antibody and T-cells to equip the immune system to respond to the alpha Covid-19 virus. In the case of the mRNA vaccines, it was really primed just toward the spike protein. If you are vaccinated and are exposed to a variant such as Delta, I understand that current vaccines have a high probability of attenuating illness. When this occurs, does your antibody response further adapt to be more efficient in warding off that variant in future exposures, or if it is good enough to work, does it remain unchanged? What exactly does or does not change? [link] [comments]  |
| Posted: 25 Aug 2021 07:03 PM PDT Like a volcano in a cold country, would the volcano be warmer than the ground around it? I understand that when it erupts there would be a lot of heat lol [link] [comments]  |
| How long is the COVID-19 incubation period for vaccinated people? Posted: 25 Aug 2021 10:13 PM PDT Is it the same as unvaccinated people? I thought it might be shorter because of a faster immune response. I couldn't find any info about this. [link] [comments]  |
| Posted: 25 Aug 2021 04:51 PM PDT If I understand the "survival of the fittest" concept, random mutations occur causing a change in a species. Sometimes, those random mutations lead to a change that gives that species an advantage. That advantage allows that species to thrive and outlive other's of its kind. It provides offspring which is more likely to be born with that new trait as well. Over time, that species with that new trait becomes the "new normal". Simply put of course. All that said, if this is accurate, how do random mutations that don't really provide an advantage also become a "new normal"? For example (this is the specific topic that got me wondering about this, so if anyone can also address this specific example, it would be much appreciated!): Humans crying when they are sad. From what I have read, it is mostly believed that the purpose of this is simply to signal our emotions to others. I am having a hard time understanding how something like this becomes a normal trait. How did this give humans an advantage that helped to out last humans other humans that did not produce tears or the other physical actions/expressions that crying produces? There are of course many other examples of this. I am sure there is a simple answer. Can any of you more enlightened on the subject than I help me understand this, or what I am not understanding correctly about evolution/SOTF? [link] [comments]  |
| Why Tuberculosis is still a major death cause if we have the vaccine? Posted: 25 Aug 2021 10:46 AM PDT I'm not an anti Vaxxer, without any doubt, but i don't understand, why are there so many deaths every year 1,4M in 2019) because of a disease that has a vaccine since almost 100 Years? Thanks! [link] [comments]  |
| Is it possible to have high inflammation and low C-reactive protein? Posted: 25 Aug 2021 11:04 AM PDT Or low inflammation and high CRP? Is CRP really *that* great of an inflammation marker? [link] [comments]  |
| Is it known if Covid is able to infect through the eyes? Posted: 25 Aug 2021 02:38 PM PDT |
| Posted: 25 Aug 2021 02:04 PM PDT Specifically, how does the plasmid enter cells and what prompts the body to start expressing proteins from foreign DNA instead of trying to get rid of the foreign material? [link] [comments]  |
| What do non-integer orbital occupation values mean? Posted: 25 Aug 2021 07:13 PM PDT computational chemistry can often spit out molecule structures that have decimal values in the calculated number of electrons occupying an orbital. What does this actually MEAN? Is it saying that an individual molecule is in some kind of "resonance" hybrid between two or more electron configurations? Or is it saying that in a sample of many molecules, those values are the *average* occupancies, but any given single molecule in the sample has either 0, 1 or 2 electrons in any given orbital?

| Why do we use latin and greek root words for scientific vocabulary? Posted: 25 Aug 2021 09:23 AM PDT Is it mostly a historical reason? Are there significant pragmatic reasons? [link] [comments]  |
