Questions about radon gas and cancer?
Can years long chronic depression IRREVERSIBLY "damage" the brain/ reduce or eliminate the ability to viscerally feel emotions?
We all know that salt can lower the freezing point of water. Are there any chemicals that can raise the freezing point of water?
What determines the color/hue when I’m blowing bubbles? The soap, size and surroundings are (roughly) the same yet some bubbles have a purple, yet other a yellow glow.
How do sailboats work when the wind is blowing in the opposite direction of travel?
Why are certain materials like parchment paper, aluminum foil, etc. not hot to the touch out of the oven while metal and glass are?
Can we use mRNA or viral vectors vaccines technology to produce other types of proteins not related to immunity?
How do springs continue to apply pressure over years?
How similar are SARS and COVID-19 (SARS-CoV and SARS-CoV-2, respectively), in the disease pathology/mechanisms?

Sorry for the long list. Once I started reading up about radon and cancer, more questions kept popping up. I'm hoping somebody here is in the know and can answer some!

If radon is radioactive, and leaves radioactive material in your body, why does it mainly (only?) cause lung cancer?
If radon is 8x heavier than air, and mostly accumulates in the basement, wouldn't that mean that radon is a non-issue for people living on higher levels?
This map shows radon levels around the world. Why is radon so diverse across a small continent like Europe, yet wholly consistent across a massive country like Russia? Does it have to do with measuring limitations or architecture, or is the ground there weirdly uniform?
If radon is the second leading cause of lung cancer after smoking, why doesn't the mapof worldwide lung cancer cases coincide with the map of most radon heavy countries? It seems to coincide wholly with countries that smoke heavily and nothing else. I base this one the fact that if you look at second chart, which is lung cancer incidence in females, the lung cancer cases in some countries like Russia, where smoking is much more prevalent among men, drop completely. Whereas lung cancer rates in scandinavia, far and away the most radon heavy place on earth, are not high to begin with.
Realistically, how worried should I be living in an orange zone, or even a red zone?

Not talking about alzheimer's or similar conditions, but particularly about emotional affect

Can we, in theory, use this technology as a delivery method to give instructions to our body to create other types of proteins and/or amino acids? Would it be possible to deliver said instructions to, for example, make the body create more collagen, actin, protein C, etc?

How do springs continue to apply pressure over years?

Posted: 26 Feb 2021 10:12 AM PST

I repair classic record players, and I've always been amazed that the internal springs can still do their job, even on a 40 year old player. It always seems like they should be much more stretched out than they are, and while I have to replace or rejuvenate some, the majority still work perfectly. How is this possible?

SARS-CoV-2 was the name chosen for the virus that causes the disease COVID-19.

Why was that name chosen? This naming makes it look like a sequel to SARS-CoV (2002). Assumingly, that means the viruses show genetic similarity.

But what about the disease? Do the viruses cause disease through exploitation of similar mechanisms in the body (similar enzymes/receptors)? I've heard the claim that SARS was a respiratory disease, while COVID-19 is a vascular disease. How accurate, or inaccurate, is that?

How do diamond paintings work?

Posted: 26 Feb 2021 05:04 PM PST

You pull the plastic cover off a sticky surfaced painting and place rhinestones over certain areas to finish a "painting".

My questions are:

1) I'm assuming the sticky surface is a contact cement which quickly dried once the plastic rhinestone has been placed over it. Why does the adhesive only dry when it is mated with another surface?

2) referring to above, if the contract cement only dries when contacted with something, why didn't it dry with the protective clear plastic over it? Did it activate once this was removed, and how?

3) how long will the contact cement remain sticky once the plastic wrap is removed? What is the process on a molecular level of adhesive drying I'm air?

Does sedement effect voltage and/or pH of water?

if sediment is sitting at the bottom or suspended in water, will this effect the water's siemens count or pH in any way?
