Sometimes two genes are inserted at the same time. One gene produces some desired product or characteristic. The other is there just to demonstrate that the other one also must be there. Care to elaborate Pax?
Wasn't that hypothesis already proven?
Yes. Repeatedly. This is nothing new.
I've made flourescent mice. It's pretty routine actually.
And CBS is wrong. Just because you can express gene A does NOT mean you can express gene B.
I was trolling for you, dude.
Not a waste of time. It proves a concept. Once you can reproducibly introduce one gene (and more importantly, express it) you can introduce any other gene you want.
They only become fixed if you don't know how to place them properly or your second doesn't know how to clean them. I've never had any trouble with them.
Oh, goody, I just learned a new knot- The Blake's Hitch. Now what's so special about it? It's a friction knot that can be used with a single strand of cord. It's like a taught line hitch on steroids.
I think Dave blew it by posting at all on RC.com. Whatever he might have said, they'd jump all over him for it, just to be cool. Internet forums are not the way to do business.

I wouldn't be too quick to dismiss this risk, just yet. I think more work needs to be done.
The HDPE are supposed to be safe. REI sells them. But do they affect the taste the water like polypropylene?
I tried testing Nalgene water for Bisphenol A by LC/MS, but it was below the detectable limit. I figure, I'd have to extract into organic solvent and concentrate to get measurable quantities.
Anyway, for what it's worth. Phenolic compounds are more soluble in alkaline solution and less soluble in acidic solution. The "harsh detergent" mentioned in the article is probably very basic (alkaline). The sports drinks most people use are rather acidic, owing to citric acid, etc.
The upshot is that if you put your bottle away with water in it, dump it out and refill with fresh before you go out.
