Data sets of asthma/other lung conditions in Asia/outside of US

For my capstone master's project, I'm trying to do something with air pollution and asthma rates/deaths and I'd like to look at some countries outside of the US as well as inside for this, preferably in south, east and southeast Asia. Does anyone know where I can look? (I'll also happily take outside of Asia, it's just that's where I'm hoping to find data.) [more inside]

What do we know about the Russian and Chinese vaccines?

And also, are they "good enough" that if a large enough population is given them, that covid will "go away"? I guess on that last one, are any of the vaccines (including the "more effective" other vaccines)? [more inside]

Why doesn't the moon rise in the same place every night?

I was never good at astronomy, obviously. But since the moon circles the earth shouldn't it rise and set in the same place in the sky night after night? [more inside]

Do your rEsEaRcH-What doyou call the type of research Qanons try to do?

I’m writing something up about Qanon researchers competencies and skills. I don’t know what kind of research they are trying to do, but I need to identify the closest type to tie it to relevant skills. My first instinct is investigative journalism but I think that’s a stretch. Historical research focusing primarily on primary sources, secondary, tertiary, quaternary and beyond as well? Bonus if you can suggest a book or resources to understand the relevant suggested research methodology. [more inside]

About the positioning of stars and planets

I'm no astronomer, so my description might be lame. But in the opening sequence of the Big Bang Theory, the viewer enters the solar system from the outer orbits, after traveling through the cosmos and beyond several other galaxies. They pass Saturn, Jupiter, the Sun, Mercury and Venus before coming upon the Earth. [more inside]

Mathematics Filter

Help a biologist trying to do math and in over their head. I'm trying to do some modeling and would like to find the inverse of the equation f(x) = ln(|x|)/u - (ln(|vx-p|))/kv + C when 0<x<p/v. Is this possible? Can anyone point me to a solution or a resource where people good at math answer these types of questions? Stuck and really not sure who to ask. Thanks!

What bug is this?

Last night I found a few bugs on a sock somewhere in my daughter's room. Can anyone identify this bug? How do I best check for more and how do I get rid of them? (The coin in the image is a Euro, for size, my guess is the bug is about 3.5 mm/0.14 inch?)

Is there any way to do citizen science around misinformation?

I have an advanced degree in an applied social psychology, work psychology. I have training in research methods/design and statistical analysis using R and SPSS, relevant subjects such as attitude, knowledge and learning theory, and some consumer behavior theory as well as real-life marketing experience. (marketing and consumer behavior seem like it might be pretty generalizable to understanding the epistemic crisis we are in). I'd like to help in any way I can and it sounds very interesting.

When might we know whether coronavirus vaccines limit transmission?

All the news articles about the SARS-CoV-2 vaccine say that we still need to wear masks, keep distance, etc., because we don't know yet whether being vaccinated stops transmission of the virus. Well, when are we likely to know the answer to this?
