comment What reasons allow for women to outlive men?
Ahh! That makes sense then :-) Even so, it would be interesting to know if they accounted for things like syphilis which might make sense in the context of this study. OK, I should read the paper ...

comment What reasons allow for women to outlive men?
Are they really saying that the lifespan of their control samples (i.e. men with testes) was only 51-56 years? That is worryingly low - I suspect that something else may be going on there .. ?

comment Is there life on other planets and if so how frequent?
Giant reservoirs of water have not been found on Europa, although it is hypothesized that there may be a subsurface water ocean due to the way that the surface ice has deformed. However, I do agree that Europa is an exciting target. Enceladus also, which has been seen to have cryovolcanos spurting out water-ice. I suspect Mars is too dry and cold. We'll see.

comment What elements are a possible basis for life?
It's an interesting question. However I suspect we'll be finding lots of weird carbon-based slime rather than anything silicon based. However, it's a big Universe out there!

@aland That's the problem isn't it? How do we know thatt whales are really intentionally beaching themselves?

comment laboratory mice, nutrition, and humans
This is an important question I think. The commonality of genes among eukaryotes does not necessarily mean they share the same metabolism etc.

comment Why do DNA and RNA have the functions they have?
I suggest going to the original refernces instead of wikipedia. Look up Gilbert (1986) in Nature for the RNA world.

comment Ramifications and possibility of a diet consuming exclusively of human semen
I downvoted because the question as phrased is not suitable for this site. Asking "what is the nutritional content of human semen" would be more appropriate for a biology forum. In what possible context would you be confronted with a situation where you had to survive on male ejaculate?
