- When a virus like Ebola kills its host before they can spread it to others, it helps lower the R0, but does there ever come a point where the R0 drops due to decreased population density resulting from deaths? If so, what determines the tipping point?

- When electricity is flowing, do electrons travel on top of a conductor or do they penetrate and flow inside?
- Can food products be damaged from being frozen at temperatures lower than the recommended -18 C (-112 F)?

| Posted: 15 May 2020 06:38 PM PDT Suppose someone figures out how to make 3 grams of antimatter leaves it to explode. How would it differ from a normal nuclear bomb? What kind of radiation and how much of it would it release? How would we able to tell it came from an antimatter reaction? [link] [comments]  |

| How many diseases can we develop immunities for? Posted: 16 May 2020 02:47 AM PDT I know that our immune system can essentially "remember" certain types of diseases to respond rapidly to them. Is there a limit to the number of diseases we can develop an immunity for? [link] [comments]  |
| Posted: 15 May 2020 08:29 PM PDT I do a lot of electrical work on cars and it's common to sometimes have to scratch a small portion of metal to remove any paint or rust when trying to find a good ground source. Got me wondering if electrons penetrate into the metal and that scratched part just acts as an "entry point" for them to get into. [link] [comments]  |

| Why does the oxidation state of Fe in haemoglobin change when an oxygen coordinates onto it? Posted: 16 May 2020 08:10 AM PDT This does not appear to be the case when ligands bind to other metals. Does carbon monoxide also oxidise iron from Fe2+ to Fe3+? What am I missing? [link] [comments]  |
| What is the hard science on mask wearing? Posted: 16 May 2020 07:32 AM PDT From this post three months ago the consensus seems to be that wearing masks was not terribly useful. It now seems that the consensus is that wearing masks should be the defacto standard. Sars cov 2 is not the first airborne virus we've had. Why has so little research been done in this area?

| Can light come in anything other than a sine wave? Posted: 15 May 2020 05:39 PM PDT If not, can other waves be approximated? Such as a square wave... and if so... what would it look like to us? [link] [comments]  |
| Where/how are antibodies stored in the body? Posted: 15 May 2020 09:07 AM PDT Is the antibody just encoded into all bodily defense mechanisms, or are they stored somewhere until the specific type is needed and then produced at that time, or none of the above? [link] [comments]  |
| What causes immunity to disappear after some time? Posted: 15 May 2020 11:06 AM PDT I often read that SARS-CoV-2 immunity may only last 1-2 years. How does that work? Also would a second exposure to the virus within that time frame "refresh" the immunity and extend it to another 2 years? [link] [comments]  |
| What is the pressure difference from the Heliosphere to interstellar medium? Posted: 15 May 2020 11:36 AM PDT I'm assuming that there's a lot more hydrogen and miscellaneous junk around the sun than outside the solar system, and for the lack of good resources or a way to phrase it to google, I just can't find an answer.

| How is the mortality rate for COVID-19 calculated? Posted: 15 May 2020 08:56 AM PDT I've seen estimates of 1%-5%. Looking at the total deaths vs. total recoveries yields a much higher number. What other factors are considered in the calculation? [link] [comments]  |
