First of all, I obviously don't think medicine is actually making the choice of where to go.

But, if I take (for example) acetaminophen for a sprained ankle, adderall for my adhd, and bupropion and lamotrigine for my bipolar, how does all of that get to where it needs to go? Is it just a matter of getting distributed evenly through the body and then absorbed wherever there happen to be receptors that fit the molecules? Doesn't that end up being really inefficient? -- seems like most of the actual meds would just get filtered out pretty quickly.

Is that were drug interactions come from? -- multiple drugs competing for the same receptors?

EDIT: holy crap. I was not expecting this quantity or quality of responses. Seriously, i think I learned more here than an entire semester of biology. Every comment is a gem. Thank you all for your time and energy! It is very appreciated.

Does putting batteries in a fridge extend their life span? personally I believe it does but the cold weather can cause rust

Does the direction a language is written and read have any effect on the hand used for writing in those languages?

Put another way: Right-handedness is predominant among languages written left-to-right.

Is left-handedness more prevalent (or even dominant) among languages written right-to-left?

Either way, does science give us any indicators as to why?

If a person were to be taking antiviral drugs when taking a viral vector vaccine, would that ruin the effect of the vaccine?

As in, would that destroy and prevent the spread of the adenovirus and thus render the vaccine useless and effectively make it as if the person pretty much received a placebo?

I live in western Washington. Sooner or later the 1700 quake will happen again.

Is there any possible way to know that two particles are entangled without measuring them in the first place?

Specifically I am thinking in the way of quantum circuits. Is there some gate combination we can run them through that does not involve measuring the original entangled pair. But gives us some separate output we can measure with a state of 1 being the originals are entangled and 0 if they are not.

Why does a higher thermal conductivity in the core lead to later inner-core formation?

Posted: 29 Nov 2021 06:51 AM PST

I am confused--intuitively, it feels like higher conductivity would cool the core faster, and so we'd get an older inner core.

But in the literature a higher conductivity is always given as a reason for a younger core (it's never really explained).

Can anyone explain what's actually going on? What am I missing here? Thanks!
