| Are they any examples of 2-way predation in biology? Posted: 04 Dec 2020 03:47 PM PST What I mean is two species who both eat each other as part of their diet. I know there are examples where the prey can be a physical threat to the predator depending on the circumstance, but I've never heard of two species being both predator and prey to each other.

| Differences between Pfizer and AstraZeneca vaccine? Posted: 04 Dec 2020 02:37 PM PST Some countries are getting Pfizer's vaccine some are getting the AstraZeneca. What are the major difference between the two? Are there benefits from one over the other? Is there a specific reason why a country like South Korea would opt for Astra's version?

| With the mRNACOVID-19 vaccine, will your ribosomes eventually stop producing the viral spike? Posted: 05 Dec 2020 08:22 AM PST I can't find much data on this, but my understanding is the mRNA vaccine turns your bodies ribosomes into viral spike factories. Will your ribosomes ever go back to normal and stop producing the viral spike? Is there any information on the potential long term negative effects of it not stoppping production?

| How are isotopes detected in stars? Posted: 05 Dec 2020 02:02 AM PST Is it just that spectrometers are super sensitive enough to do this? Or is there some other trick to it? I'm reading a passage about how oxygen isotope ratios of ¹⁸O/¹⁶O become systematically lower with distance from the galactic centre, and I was wondering how on Earth they measure this? Bonus question: why does this apparent trend occur? The book I'm reading is more focused on the Solar System rather than the galaxy, so it simply states that "this actually represents a Galactic evolutionary phenomenon, which we will not study further here."

| Why does masturbating make a smell in your room? Posted: 04 Dec 2020 05:54 PM PST My mom would always point out a weird smell... I think she knows, maybe she doesn't IDK But why does masturbating make the smell? Is it the semen that is released? Hormones? Or is it the vigorous exercise? [link] [comments]  |
| How did epidemics and disease affect natural populations before humans existed? Posted: 04 Dec 2020 11:52 PM PST Before humanity forced animals nature and people into extremely close proximity how common and devastating were disease epidemics? Have they been responsible for much in the way of a natural population control or evolutionary 'balancing' process? [link] [comments]  |
| Could Different Covid Vaccines Interfere With Each Other Across Populations? Posted: 05 Dec 2020 05:30 AM PST What I am asking is the following scenario: Could I be at risk of catching Covid from the people who have received a different vaccine than I, even though I wouldn't have to worry about people who have been vaccinated with the same vaccine as I was?

| Posted: 04 Dec 2020 09:24 PM PST I know that Shingles is a reactivation of the virus that causes Chickenpox, and if you haven't had Chickenpox, you can't get Shingles (although you can get Chickenpox from someone who has Shingles). Are there any other viruses that lay dormant and cause a future infection? Is SARS-CoV-2 a type that could reactivate later? [link] [comments]  |
| Posted: 05 Dec 2020 03:50 AM PST I can't find any numbers online. Also, how many people do you believe we would need to test before we can have an accurate idea of what to expect? [link] [comments]  |
| Posted: 05 Dec 2020 02:03 AM PST I've done a little bit of research, looking at NHS, APA and DSM-5 definitions and diagnostic criteria, and I had some confusion around what I perceived to be internal inconsistency in the definitions provided. Can science explain, please? [link] [comments]  |

| What are the known risks of vaccines? Posted: 05 Dec 2020 05:21 AM PST How known are the risks of vaccines? How accurate are we at predicting the risks? For example, do we know if certain types of vaccines are only going to cause a known range of symptoms, or are we so unsure that we don't know if a particular/type is going to shutdown people's livers until we do trials?

| Are there any animal species where both sexes are sexual selectors? Posted: 04 Dec 2020 05:29 PM PST First off: sorry if I use any terminology wrong. As I understand it, pretty much every animal species has one sex (usually female) that is the sexual selector, so they're basically the "choosy" one. The other sex (usually the males) then has to sort of earn the right to mate through like fighting or just having the right body parts or dancing, etc. But I always get the impression that the males will pretty much just mate with any willing female. Anyway, I was just thinking: wouldn't it be advantageous if both sexes were selectors? Like if both sexes were choosy and therefore both had to be at the top of their game so to speak in order to mate, wouldn't the fitness of the species be better overall? [link] [comments]  |
| Is there an amount of viral load that would overwhelm an immune individual? Posted: 04 Dec 2020 09:06 PM PST The traditionally immunizable diseases -- chicken pox, mmr, shingles, hep, rabies, etc -- is there some viral load that my immune system would be incapable of fighting off? [link] [comments]  |
| Do flu shots ever provide *some* protection against other non-covered strains? Posted: 04 Dec 2020 08:56 PM PST If they formulate a given shot to cover 3-4 particular strains, would a person getting the shot have some theoretical protection against other strains in the same 'family' of viruses? Like maybe you'd get sick but not as sick as you could have? [link] [comments]  |
| Why is a fourth satellite needed for time information in GPS location? Posted: 04 Dec 2020 02:00 PM PST I understand the onboard clock in GPS processing units aren't an atomic clock cabable of giving the information for variable T, but if all GPSs are equipped with these highly accurate atomic clocks, couldn't one of the satellites already transmitting X Y Z also give data for T rather than having a seperate satellite for X Y Z and T? Sorry if this is a dumb question, I am studying to be a pilot and am onto my instrument rating, I want to try and understand the GPS system to the best of my ability. [link] [comments]  |
