Why aren't more people cured of HIV with bone marrow transplants?

It's been 13 yrs since the first person was cured while attempting to treat their cancer and several others have been as well. Why isn't this used as a treatment? Is it just because it's so hard to find a match? If so, why isn't there a HUGE push for sites like Be The Match? Every time it happens every article just says "this may lead to a cure" well it's been over a decade now.

Have we ever found alive specimen of a supposedly extinct specie?

Are there any chances that a supposedly extinct specie could still be around, a small number of them. Was this ever the case in science, finding something allegedly extinct?

What would happen in mathematicians decided to change the order of operations? Would math still work if everyone agreed, or is something about it intrinsic?

What waves are used for aircraft communication?

Posted: 30 Sep 2020 09:41 PM PDT

Is it radio waves or microwaves, because I wrote radiowaves in my exam and I lost one mark. According to my teacher, it is microwaves. I googled but some sites say micro and some other say radio. So what is the real answer and can I demand to get my one mark which he deducted?

How come when you wet a piece of paper and then let it dry it gets all crinkled and makes a crinkly noise when folded?

Posted: 01 Oct 2020 07:09 AM PDT

So I was messing with some watercolors and the paper was getting all stiff and crinkled after I'd finish wetting it, I know that's just what happens when you wet the paper but why does it happen, is it just setting the paper and setting it into place crinkled or Is something else happening with the water and paper? I have no clue if it's physical or chemical why this happens.

What process causes the cells to become cancerous when smoking cigarettes?

Posted: 30 Sep 2020 12:56 PM PDT

When smoking cigarettes the cells have the potential to go cancerous, but why ? What is the cause ? And if there would be a way to circumvent it is it possible ? Such as smoking organic tobacco grown in your own back yard, with no harmful additives added .

Why are cloud bases flat but cloud tops fluffy?

Posted: 30 Sep 2020 08:26 AM PDT

In a typical cloud you see in the sky or drawn, the cloud base is flat and the top is fluffy. Drawing example and photo example.

I know this pattern seems to be developing in cumulus clouds of some vertical extend at least. I understand that, in the idealized model, these clouds form in an unstable atmosphere, and that rising warm air pockets cool at the dry adiabatic lapse rate before they reach the temperature of the environment at the dew point (the intersection of the DALR line and the ELR curve), at which humidity is 100% and water starts condensing as the air pocket keeps rising, now at the saturated adiabatic lapse rate. However, it's unclear to me why the condensation stops at irregular patterns of altitude at the top of the cloud, but seems to be starting all at the same altitude at the base of the cloud.

I thought of several explanations for this: That the temperature of the atmosphere isn't uniformly distributed according to the ISA atmosphere; that there are insufficient condensation nuclei and some water cannot condense and these are not uniformly distributed; or that the humidity of the air pocket is not uniformly distributed. However, these hypotheses do not seem to explain the discrepancy between the base of the cloud and the top. So, what's really going on here? Thanks!
