comment Magnetic-activated cell sorting vs. FACS
@canadianer true, I hadn't thought of that. I'm an antibody guy, so I usually think in that direction :)

comment Magnetic-activated cell sorting vs. FACS
@canadianer assuming one would want to use live sorted cells in their subsequent experiment(s), FACS has the same constriction.

comment How do disinfectant sprays work? Difference with antibiotics
Can you please focus on a particular class of disinfectants, such as Lysol spray, 70% alcohol, or bleach (sodium hypochlorite)? This will keep the question from being closed as "too broad" and help us to focus our answers.

comment What is Vagal modulation of Heat Rate?
This question is far too broad (it contains 5 questions, not 1), and could be answered by doing some basic background research first. Please read the help center and take the tour to learn more about this site, how it functions, and what is expected of questions.

What do you mean "while staying as close to real humans as possible?"

comment Experiment using nocadazole
The concentrations and timepoints used entirely depend on what sort of effect you're looking for.

comment Safety of cobalt-chromium and nickel-chromium dental implants
@so2 I understand. I'll update the answer as soon as I can (I'm at work now, and a bit busy).

comment Safety of cobalt-chromium and nickel-chromium dental implants
@so2 that page is full of random quotes from dentists, unsourced claims, and links to other unverified websites, without a single citation to reputable peer-reviewed literature or actual evidence - it's scare-mongering. Just because a doctor associated with a medical institution says something, doesn't mean it's true - you need evidence. Yes, heavy metals on their own can be highly toxic. However, as I described in my answer, amalgam is an alloy of different elements, and its chemical properties are entirely separate from the properties of the individual components that make it up.

comment Why are there no trees in Texas?
@questionhang my last sentence should address your question. There are drought-resistant trees, and fire-resistant trees, and flexible, tornado-resistant trees, and trees with deeply-penetrating root systems, and trees that are resistant to extreme changes in climate, but not all in the same species. It's not any one factor that prevents trees from growing, but the combination of them all together.

comment Why are there no trees in Texas?
I've edited the question and nominated it for re-opening. I think it's clear what the OP is asking, even if the premise is faulty.

@questionhang see my edit above for some reasons.

comment Can a person's body produce enough electricity to break a wristwatch?
I do think this has the potential (haha, electricity joke) to be a very interesting question - there's a lot of anecdotal evidence out there about people (a friend of mine included) who cannot wear watches because they are continually dying or otherwise malfunctioning. It would be great if someone could find a study on this.

comment Why are there no trees in Texas?
@questionhang there are plenty of places like that across middle America, and around the world. Here, we call it "prairie," in Europe and Asia it's called "steppe," and in southern South America (especially Argentina) they call it "pampas." There is sufficient rain for grasses, and trees can survive if planted and maintained, but they generally do not prefer to grow there.

comment What is a complex?
@Remi.b no, they do not need to be answered. If they are answered, they should be answered correctly, which I agree to, instead of posting a link to LMGTFY. However, I think canadianer's comment is a completely sufficient answer, and after it the question can be closed as homework. I don't think this site should be for explaining every single piece of terminology (especially extremely common terminology) that is come across in a paper or textbook. A very important part of learning is being able to find answers for yourself, and not just asking someone to answer it for you.

comment Before Evolution was proposed by Charles Darwin, what were the leading secular theories to explain how life developed?
Of course, not all things behave this way - we know that ducks come from duck eggs, and puppies come from a bitch, and so forth, but when you don't have the knowledge or creativity to set up a completely controlled experiment, it all seems to make a great deal of sense. Remember, the average level of education back then was much lower than today, and most "scientists" (they called themselves natural philosophers) were self-taught.

comment Before Evolution was proposed by Charles Darwin, what were the leading secular theories to explain how life developed?
@GabrielFair absolutely. And it makes total intuitional sense - you take a piece of meat, put it outside, and within a relatively short period of time it has maggots on it. Same thing with hay - cut and dry it in the field, put it on the wagon and bring it back to the barn, and before you know it there are mice in it, which certainly weren't in there before. It feels completely logical. Besides, fresh hay doesn't produce maggots, and rotting meat doesn't produce mice, so the "seeds" of those animals must be within the originating substance.

comment Why should or shouldn't we allow the human body to take its natural course?
Dehydration/hyperthermia isn't just an issue for elderly people, it can affect anyone.

comment Why didn't a concept like “pointers” in Computer Science evolve in the genome?
@Resonating "50% of your genome doesn't do anything at all" is not necessarily true. A large portion of our genome does not have any currently-known function, but that is completely different from saying it has no function whatsoever.

comment DIY storing family DNAs' samples for future uses (eg medical)
I don't think OP is asking about storing live cells, but rather DNA. You certainly don't need liquid nitrogen for that, once you've purified it.
