comment What is the oldest example of DNA identified?
My understanding was that DNA in non-living matter had lifetimes of thousands of years, not millions. How did such ancient DNA manage to be preserved? Does this result hold up?

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 ...

Very interesting though!

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.

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!
