Why is it recommended to avoid lying down after taking iron supplements?

Posted: 23 Mar 2020 08:42 AM PDT

The instructions recommend staying upright for 30 minutes afterwards, why is that? I wonder why don't I see this with things like antihistamines or painkillers. It is a 200mg iron fumarate supplement, if that helps.

Are quantum fields in any way similar to classical fields?

Posted: 24 Mar 2020 05:45 AM PDT

I understand classical fields as being functions of space with spatial(-temporal) coordinate inputs and scalar, vector or tensor outputs (like temperature being a function T(x,y,z,t) with a single scalar output). But when people talk of quantum fields, they talk of "exciting the field to produce particles" and other things that refer to quantum fields more as physical media that can be disturbed and picked apart. Am I missing something big here? Or is QFT just so complicated that it's not worth comparing quantum fields to classical ones?

Has there ever been a recorded pandemic for marine life?

Posted: 23 Mar 2020 07:30 PM PDT

Hi everyone, pandemics seem to be a hot topic right now, and rightfully so, but I was wondering if there have ever been any devastating marine viruses, pandemics, or plagues? Humans have a long history with plagues but I've never heard of marine life being effected by that. Thanks for your time!

Why does the measles virus stay in the air so long?

Posted: 23 Mar 2020 08:02 PM PDT

It is actually bigger than the coronavirus which is less contagious .. what are the mechanics that allow the measles virus to stay aloft for hours?

Thanks

Do piranhas eat other piranhas? Piranhas are site and scent hunters. So, if one of the piranhas got injured during their feeding frenzy or something, can other piranhas distinguish between food and this injured piranha?

Can the placebo effect activate the immune system?

If a doctor tells someone that they're sick when they're not, can that person's immune system be triggered despite the fact they're not sick?

Role of calcium ions in stomatal closure?

Posted: 23 Mar 2020 04:04 PM PDT

Hi I do A level biology and I am confused with what the role of calcium ions is. I understand that it acts as a secondary messenger but not quite sure what it does to assist with closing of stomata. Any help appreciated.

Do the Nuclear Forces have analogs of the CMBR?

Posted: 23 Mar 2020 07:18 AM PDT

I'm guessing that like EM, at some point the universe was just cool enough that the strong and weak nuclear forces became distinct. At each of these points, wouldn't there have been a sudden burst of gluons and W/Z bosons throughout the universe which we should be able to detect? Or at least can we detect what they decayed into?

EDIT: Also might not something like this exist for gravity?

Why did SARS-CoV (Ro of 2-5) not spread to the same levels as SARS CoV-2 (COVID-19) which has an Ro of 1.4-3.9?

Posted: 23 Mar 2020 11:14 AM PDT

SARS had a higher CFR, but also a higher Ro, so why did it not reach pandemic proportions like COVID-19 has?

If your body produces antibodies after defeating a pathogen indefinitely, when an individual gets exposed to many pathogens throughout their life, will they have a larger antibody density in their blood? Is there a limit to this?

What ACTUALLY happens to a person when they take hydroxychloroquine and azithromycin? Or just chloroquine and azithromycin?

Posted: 23 Mar 2020 10:49 AM PDT

I've tried to find the question on here but couldn't, but I wanted to know what happens to a person when they take this and the reaction that it causes, or perhaps the compound that it makes? I've tried googling the interaction but really couldn't find what I was looking for. Any answers are appreciated!

In the context of Covid-19, is herd immunity something that can help stop the spread of the virus? How and when would it set in?

Posted: 23 Mar 2020 12:38 PM PDT

I've heard that herd immunity is something that can help stop the spread of covid-19. Is this true? If it is, what does it entail and how long would it take for it to take effect?

How did the Florida Everglades form?

Posted: 23 Mar 2020 09:24 AM PDT

I've found conflicting information about the geographical development of Florida. I've read that about 2mya the water level was 20m higher than today, but then I've also read that the Florida peninsula extended over 100mi further into the Gulf of Mexico than today. Additionally, I've read that the land was basically a desert 7500y ago, but then it was an archipelago 6000y ago? I can't seem to find reliable sources that have definite (or as accurate as we can get) answers. Can someone clarify the timeline and describe what the land may have been like leading up to modern times?
