| How does the standard model of particle physics explain Newton's laws of motion? Posted: 20 Jun 2020 04:05 AM PDT The way I understand it, the standard model of particle physics describes four fundamental interactions: electromagnetism, gravity, the strong force, and the weak nuclear force, gravity being unexplained in specific terms. Where then does Newton's "F" in F=ma come from (in particular the "applied force"), and why does it act upon aggregates of particles according to the Newtonian laws of motion? [link] [comments]  |
| Do creatures with shorter lifespans evolve faster? Posted: 19 Jun 2020 05:33 PM PDT Maybe I'm wrong with this but my (very) basic understanding of evolution is that there are genetic mutations in a species that "win" over vast amounts of time and change things as a result. So, if you have certain creatures that only live a few years, then wouldn't any mutations happen faster if they were far more generations to travel through? [link] [comments]  |
| What causes shingles (and the zoster virus in general) to manifest as a rash? Posted: 20 Jun 2020 06:46 AM PDT Shingles is a reactivation of the varicella-zoster virus. In searching online, I haven't been able to find out what triggers the virus to exhibit a painful rash with blisters. Why is it a rash instead of, say, a sore throat? [link] [comments]  |
| Can an individual be continuously reinfected by a virus? Posted: 19 Jun 2020 07:24 PM PDT For example, if I have a bad cold and am sitting in my room all day retouching the same objects over and over, am I continuously reinfecting myself (or "erasing" my body's progress of fighting it) by taking in more of the virus?

| What exactly is the lymphatic system for and what are it’s evolutionary origins? Posted: 19 Jun 2020 12:32 PM PDT I've always learned answers such as "it's important for the immune system" and also that it aids in fat transport. However, it seems excessive to have a separate vessel system just for those purposes, when the circulatory system is generally adequate for most immune response and nutrient circulation. How did the lymphatic system evolve and remain present? Did it once hold greater importance? How bad would it be if someone didn't have it? [link] [comments]  |
| Are the chances of multiple vaccine prospects for COVID-19 working correlated or independent? Posted: 19 Jun 2020 07:55 PM PDT The NY Times is tracking the number of COVID-19 vaccines in each phase of human trials. If one of these vaccines fails does that mean others are more likely to fail as well, perhaps due to some underlying trait of the disease, or are these independent rolls of the dice? Do we get more information from a failed trial about if other vaccine prospects are likely to work? [link] [comments]  |
| Assuming that coronavirus antibodies only last for a few months, what would this mean for immunity? Posted: 19 Jun 2020 09:23 PM PDT There was an article in r/science that said that there is evidence that COVID antibodies may only last for two to three months. Does this mean that your immunity would end after that time period if you had already caught the virus? Does that mean a potential vaccine would only be effective for a few months? How will this affect attempts to eliminate the virus in the future? [link] [comments]  |

| Why is there a high tide in the opposite side to the moon? Posted: 19 Jun 2020 01:40 PM PDT It makes sense why there would be a high tide facing the moon, because the moon's gravity pulls the water. But why a high tide on the opposite tide, therefore 2 high tides a day? [link] [comments]  |
| Which is more efficient, high or low altitude flight? Posted: 19 Jun 2020 09:20 AM PDT I know nothing about this but I was just considering air density and flight. I think low altitude has higher density air which would make more friction on a fuselage and slow an aircraft down BUT the engines would have more thrust/material to push. In very high altitude there would be less friction but also less air/material for the engines to push so they might have to work harder to go the same speed? I suspect that it might depend on what speed an aircraft wants to go. Also, getting to altitude might remove any efficiency advantage of high altitude flight. Think Solar Impulse versus the X-15. Which is more efficient, very high or very low fight? [link] [comments]  |
| Why are smartphones cameras so small? Posted: 19 Jun 2020 04:48 PM PDT As I understand, the bigger the sensor, the more light goes in and the better a image is. So, why must smartphone cameras be so small? There is plenty of space on the back [link] [comments]  |

| Posted: 19 Jun 2020 02:50 PM PDT I was reading a bit in the famous Gray's Anatomy about some functions of the left recurrent laryngeal nerve's unusually long pathway. One section says: "As the recurrent laryngeal nerve curves around the subclavian artery or the arch of aorta, it gives several cardiac filaments to the deep part of the cardiac plexus (Gray's Anatomy, 1980, p. 1081). I've tried to find out what exactly that means, but I'm struggling to understand what "cardiac filaments" are. Any help would be most appreciated. [link] [comments]  |

| Posted: 19 Jun 2020 11:09 AM PDT Let's say you get exposed again after building immunity. Is there a period where the virus is able to spread before your immune system can kill it? [link] [comments]  |
