| Is it possible to create a contagious Vaccine? Posted: 21 Jun 2020 10:21 AM PDT I know a lot of half of the information. When learning about the multiple vaccines being developed, I believe one was having portions of the virus (but not the whole code) implanted in another virus to stimulate an immune response. Along with that I believe I heard that weapons manufactures want to splice different diseases with whooping cough to create airborne version of the diseases. Is there a safe way to do this with Vaccines? And if its something that could possibly happen down the line do you think the anti vaxxers would start wearing mask then? [link] [comments]  |
| How is it possible that the Covid19 virus is becoming less deadly over time? Posted: 22 Jun 2020 06:16 AM PDT I read this article and wondered how it's possible that the virus is becoming less deadly / transfarable naturally? How does this happen since the virus is widely spreak, it's not like they can communicate or is human kind acting as a sort of filter where interacting with humans creates a less deadly virus. I believe something similar happened to SARS. [link] [comments]  |
| Why do some viruses or bacteria stick around forever (barring treatment) and some just go away? Posted: 22 Jun 2020 03:13 AM PDT Does it have more to do with the virus/bacteria itself or the part it infects? Seems like flu-like viruses all fade, whereas STIs stick around. [link] [comments]  |
| Posted: 22 Jun 2020 06:22 AM PDT I can understand how e.g. radiowaves can be generated by switching an antenna on and off very quickly, and how quickly I switch produces the frequency of the wave. But what does this function of switching on and off that gives light its frequency? [link] [comments]  |

| Why don’t radios get interference from light waves? Furthermore could a radio pick up light waves? Posted: 21 Jun 2020 07:53 PM PDT I don't have much experience with the physics of light waves and radio waves but I do have enough that I was able to pass the exam to get a radio operators license and I just realized: if lightwaves are considered a part of the electromagnetic spectrum than does it cause any interference with radio equipment? I live near a hospital and frequently will get a lot of interference on my radios whenever they use their MRI machine and the frequencies used by those machines are much higher than that of light.

| Why are COVID cases increasing so quickly while deaths are steadily decreasing? Posted: 21 Jun 2020 09:09 AM PDT Is it just that the death rate lags behind the identified cases? Are more cases being identified due to increased testing? Is there some kind of difference in the reporting of infections and/or deaths compared to several weeks ago? [link] [comments]  |
| What do we know about the longer-term effects of catching and recovering from COVID-19? Posted: 21 Jun 2020 01:02 PM PDT While I know that it's only been a few months so trying to get some objective reports on longer-term effects is premature. Have there been any studies on this so far? As everyone seems to focus heavily on the deaths, there's a growing number of people that have recovered, or are recovering from being infected. And there are anecdotal stories about people who say "I'm only back to 65%" or "there may be scarring on the lungs" or the like. I'm having some trouble going beyond just anecdotal stories. So, is there any hard science -- yet -- on the lasting effects of recovering from the virus, if any? [link] [comments]  |
| How can the Mars Ingenuity drone fly when Mars is nearly a vacuum? Posted: 21 Jun 2020 08:30 AM PDT Mars Ingenuity is a drone set to be launched as part of the Mars 2020 mission next month. Mars has an atmosphere less than 1% as dense as earth's, "equal to the density found 35 km above the Earth's surface". How can a drone operate in a near vacuum? [link] [comments]  |

| When it comes to treating viral infections why aren't serums used more often? Posted: 21 Jun 2020 06:31 PM PDT I heard off handedly that serums might be used in the Corvid 19 and it made me think why don't more viral infection treatments take antibodies from people or animals that resist them and use them for treatments? Seems these days it's either antivirals, vaccines, or nothing. [link] [comments]  |

| Can plasma transition directly to a liquid or a solid, and vice versa? Posted: 21 Jun 2020 11:09 AM PDT One of the first things learned in physics is the four fundamental states of matter, and how to transition between them:
The first three states are all able to transition between each other through various processes, but I only learned about gas and plasma transitioning between each other. Is it possible to plasma to transition to and from another state of matter besides gas? [link] [comments]  |
| What are crystalline porous materials? Posted: 21 Jun 2020 10:05 AM PDT I'm currently trying to get a decent understanding of this chemistry research publication but there's a few terms I'm not understanding, like "crystalline porous materials" or CPMs. I tried searching a basic definition online but all sites/links related to this are just even more detailed research papers which I don't understand. Does anyone happen to know how to explain what this is for a undergraduate student? Thank you so much! [link] [comments]  |
