comment How to DIY preserve pet DNA today so that it can be used in 20 years
Its possible that we will have machines that can take DNA from a DNA prep and produce a living cell... well, we can do that for bacteria!

comment Human Body “Fat” Equilibrium
@DanielStandage: that is exactly my point. As it stands it looks like with any combination of x and y you will never gain weight. I am not doubting that SOME people may not gain weight for y<<x but that would definitely not be the norm.

comment Human Body “Fat” Equilibrium
What makes you think your theory is true? Definitely your first premise is false, otherwise nobody would ever gain weight...

comment Decreasing the alcohol proof and faster in hangover, why?
well, it's not the decrease, but the fact that if you start with vodka rather than wine you'll get intoxicated faster, as there is more alcohol in it.

comment Decreasing the alcohol proof and faster in hangover, why?
Are we speaking of faster hangover or faster intoxication? In the second case the answer is trivial I would say... in the former I wouldn't see the utility for a secret agent to do that

How much distilled water do you have to drink to get acidosis? Coke has a pH of ~2.5...

comment Is it true that newborn babies don't produce tears while crying? Why?
This does not really answer the question of whether newborns cry without weeping. They have a lacrimal system, but that does not mean that 1) it is fully functional and 2) they use it when crying.

comment Are there any structures in mammals that are used only by males?
@Shep: my point is the fact that an example of a shared structure that is used only in females exist does not in any way imply that the opposite should also be true. It could, but there is definitely no causality here.

but it seems like the opposite should also be true. Why?

comment Is it true that newborn babies don't produce tears while crying? Why?
See my comment here: biology.stackexchange.com/questions/2087/… Seems to be related to insufficient development of their nervous control (at least according to Wikipedia)

comment Is there an evolutionary advantage to crying when sad?
It seems to me that your neoteny hypotesis just shifts the question. How did crying evolve in human infants? Animal pups only have the "vocalization" part of it, by the do not shed tears... (also, as Wikipedia reports, human newborns often cry without weeping, probably because of insufficient development of their nervous control)

@Peter Tamaroff: because I don't know any paper showing that (but I would be very interested in seeing one)!

comment Do trees age on a microscopic level?
Although I understand telomeres are fancy these days, I wouldn't really restrict aging at the microscopic level to their shrinkage. There are many more things going on, telomeres are surely one of the components of aging, but they are not the only one.

comment What is a coupled reaction and why do cells couple reactions?
Think of this: would you rather take a can of fuel and burn it or take a can of fuel, put it in a car and let it burn (in a controlled way) in there?

comment Is it possible to live without health problems sleeping one day and not the other?
You may want to cite some paper showing that perturbation of sleeping results in significant perturbation of hormonal rhythms.

comment Downloadable worldwide database of disease statistics?
In general it's always better to politely ask and wait for a reply. Cross-site scripting means you are using their bandwidth so you should only do that if you have permission.
