Does the auditory nerves activate, when we hear the voice of our thoughts?

I was wondering whether the nerves that are firing when we process sound activated, when we "hear" sound in our mind. Same could be asked for visualizations.

How does the immune system work outside the bloodstream?

I know we have white blood cells and other immune cells floating around in our bloodstream that attack pathogens, but how do our bodies fight infections that occur outside the blood vessels?

Is there any way to use the polarization of electromagnetic radiation to transmit information?

Posted: 18 Feb 2022 01:54 AM PST

I'm currently educating myself about electromagnetic radiation, mostly with a focus on environmental and health concerns, but hopefully with a solid physics background.

I just read about how EM-waves are modulated in three ways for the transmission of information in technical applications: amplitude modulation (AM), frequency modulation (FM), and phase modulation.

Light is also a kind of EM-wave, and I remember from chemistry class, that light has another characteristic feature: polarization. I suppose this also applies to other kinds of EM-waves.
Is there any sort of application, where the polarization of EM-Waves (like radio waves) is used to transmit information? Is this even theoretically possible?

I would really like to learn more about this subject. So please enlighten me! (pun definitely intended)

Does working out specific muscles as a child cause those muscles to be bigger or more defined permanently as an adult?

Posted: 18 Feb 2022 02:29 AM PST

I'm probably not wording this right, but say you ride a bike in a really hilly area for years as a child and you develop large and strong quads and calves from it, are you more inclined to have bigger leg muscles, naturally throughout your adult life?

I know a few people with naturally big, specific muscle groups, and I when I ask if they work out those muscles the answer is usually no, but that they did some kind of activity as a kid which made those muscles big, and now they're just naturally big forever.

Food safety sources often say that re-cooking questionable food isn't safe because, although it may kill bacteria, the contaminants could have produced "toxins" that won't be destroyed. Is this true? What are some examples of this?

Posted: 17 Feb 2022 08:59 PM PST

You made a mistake with your food -- you left it out too long, or cooked it at too low a temperature. But it's not salvageable. You have to toss it, because while re-cooking it properly may kill bacteria, it won't remove the "toxins" they could have produced.

I've seen this many times over the years and it always seems like folk wisdom that's repeated without a complete understanding. I've never seen an example of what these toxins may be or what contaminants may produce them.

Suppose some meat was left at room temperature for 24 hours, well outside the FDA "danger zone" (40 to 140 °F for more than 2 hours). If that meat is then thoroughly cooked at high temperatures for an extended period of time, what specific risks remain?

I would guess there are also factors involving bacterial population... i.e., eradicating a large population of E. Coli that grew over 24 hours is maybe more difficult than killing a smaller infection. But I'm specifically interested in the idea that bacteria or other parasites may produce byproducts that go on to survive a thorough cooking.

If you could, theoretically, inject live cancer cells in a body would that person get cancer?
