comment Is there a superterm combining “animal line” and “cell line” in disease models?
No, because not all mice or cells are genetically modified. The Black Six and NMRI I listed above are examples of wildtype mice, and they are still lab lines.

comment Are there cats with black skin?
Sorry, I have the habit to read the answers very quickly after they are posted, upvote, and think that I will wait a day or two to pick the best one. Then I forget to come back and accept :( You are right that your answer is really good and accept worthy, thank you for writing it.

comment Can you recharge without sleeping?
I suggested a very radical rewriting edit in order to remove all "personal health problem" wording and thus have the question qualify for reopening. You don't have to accept it, of course. But I think that with it, your question has a chance of getting open again and gathering more answers.

comment Why do some medicines induce sleep?
@InfiniteLight I don't see how reducing it to three-four mechanisms will help. "Why are there many medicines which are H1 receptor antagonists" is not a good question, there is no good reason why there are several of them. Also, I wouldn't say that some mechanisms are more "common" than others, common by what count?

comment Why do some medicines induce sleep?
I'm torn between flagging this as way too broad and thinking that it is a good opportunity to clear up basic misconceptions about drugs in an answer. In any case, I recently noticed that a standard book on pharmacology has three separate chapters entitled "how drugs act", this should give you a hint why the question is hard to answer in this state. Note that these were basic overview chapters, before delving into what specific classes of drugs do.

comment Can you recharge without sleeping?
@Luke I did. Kandell (or rather the chapter author, K. is the editor) says that part about the "kill you sooner". I don't think I can find the exact page because I have the Kindle edition.

comment Are we more attracted to people of the same ethnicity?
There is a good chance that there is a relation mediated by oxytocin, a hormone which influences both romantic attraction and distrust against outgroup members. But I don't know its exact mechanism of action (especially the causal direction of oxytocin release, falling in love, and stranger distrust) to post an answer, so I hope somebody with better understanding will post an answer about that.

comment If a trait would be advantageous to an organism, why hasn't it evolved?
I actually like this answer. This kind of question makes the most sense in a mental model which silently assumes intelligent design of organisms, even if the asker believes in evolution and is unaware of the inconsistency of his knowledge structure. All the other answers explain the points in which evolution behaves unlike intelligent design, but this one also notes which core assumption is responsible for the misunderstanding.

comment How can I keep pond water “alive”?
You want to keep live water indefinitely? I don't know if you'll be able to tell if it gets colonized by Legionella.

comment Do we have evidence of heritable personality traits in chimpanzees?
@WYSIWYG the Big Five are considered to have up to 50% heritability in humans, so I don't see a problem with the premise. I don't know if there is sufficient research on personality traits in apes (or how researchers would deal with the distortion which being lab-reared will introduce to a twin study), but I find the question quite interesting.

comment If eating 100% fat 2 times more worth the energy I spend during the day, will I store body fat?
"is the one that tells the body" sounds like a strange way to say it. The response to food is regulated by many more hormones and neurotransmitters. For example, gut cells secrete GLP-1 in response to both fat and carbohydrates. I don't know all pathways involved but I'd be very surprised if insulin is the only mechanism involved in telling the body to store fat. And then there is the theory that the trouble behind metabolic disorders doesn't come from storing too much fat, but from storing too little fat - the overconsumed but unstored fat would wreak havoc in different tissues.

comment Consequence of Plants as Incomplete Protein Source
You seem to miss that the concept of essential amino acids is human-centric. Why should a plant encode all the amino acids needed by a human? The plant doesn't need them.
