comment What determines the (perceived) frequency of tinnitus?
@Jeff Interesting, but rather indigestible and verbose. Would be nice to get an answer that explains things in simpler terms.

comment What chemicals can be detected from one's sweat?
I recently watched a documentary in which a team demonstrated a type of sensor that would compute blood sugar levels from sweat, which was pretty neat. I guess a lot of stuff is leaked out that way.

comment Serotonin - Does being aroused make you sleepy?
I've always wondered whether heightened serotonin was responsible for socially accepted phenomena such as post-coital tiredness and "morning glory"...

comment Why is glucose our primary source of energy?
I don't have a direct answer for you, but you should try to get hold of a copy of Romano AH, Conway T. (1996). "Evolution of carbohydrate metabolic pathways".

comment Predictable microchimerism
Found the article! It's in edition #2869, on page 12. Got a jpeg of it here.

comment Predictable microchimerism
@jonsca Nope, this was recent, perhaps a month or so old. I completely forgot about this last night, but I'll try to remember to dig out the article tonight.

comment Predictable microchimerism
I remember it mentioning increased risk of transfer of diseases, so I'll dig out the article tonight and post an excerpt.

comment Predictable microchimerism
This seems to be counter to what the article I read said. They indicated that genetic material from siblings and a grandparent was found in children.

comment How is the blood volume of a living organism measured without killing it?
Yeah, that's kind of what I was thinking about. My method was a little less refined and involved a lot of "glowing area measurement", but it's essentially the same principle.

comment How is the blood volume of a living organism measured without killing it?
Could this be done with radioisotopes? I'd imagine a set of scans from different angles could give a reasonable estimate of blood volume.

comment What actually happens when my leg 'falls asleep'?
Whilst it's not particularly academic or explanatory, this article does give you a basic explanation in layman's terms: health.howstuffworks.com/human-body/parts/question552.htm - I too would be interested to know the details, though.

comment Altering the human genome
Thanks for the answer. I hadn't considered nanotechnology as a possible injection payload - certainly very interesting stuff! I'll read through those wiki articles for more information.

comment Altering the human genome
Thank you very much for the detailed answer. I'll certainly have to read into behavioral genetics!

comment Mechanism of syndesmophyte growth in AS
Interesting. So the symptomatic inflammation over long periods of time ultimately causes fibrosis and fuses the vertebrae? Also, what causes the lack of oxygen at the site?

comment Which aspects of renal physiology are standing in the way of an artificial (mechanical) kidney?
I'm aware of this, but transistors are highly complex in comparison with a mechanical device. In the case of producing very fine filters and sponge-like structures, 20nm is no big deal.

comment Which aspects of renal physiology are standing in the way of an artificial (mechanical) kidney?
Note that the above just refers to the overall transistor size. The internal layers and interconnects are often smaller than 1nm in at least one dimension. Clearly we already have the capability to produce simple parts at a much smaller scale than 100nm.

comment Which aspects of renal physiology are standing in the way of an artificial (mechanical) kidney?
I question your "100nm scale microprocessors" remark. We can manufacture microprocessors down to at least 30nm, if not lower. I think the current minimum transistor size is 14nm. Update: Intel and IBM are using 14nm in next-gen fabrication, several other companies are using 15nm. Intel have also been experimenting with 12nm and 11nm units.

+1 for that GIF, it's mesmerising.

comment What are the major evolutionary pressures for Bioluminescence?
Whilst it's not exactly academic, the BBC documentary "Blue Planet" had an excellent episode on deep-sea creatures, containing a large section about bioluminescence. Well worth a watch.

comment Are there any pre-Holocene venomous animals?
It always tickles me that the platypus is poisonous, despite looking so ridiculous.
