E. Coli could never have started producing human insulin without a genetic modification. A tomato could and have naturally evolved to have 3 carpels. With selective breeding we just used that mutation because it gave us bigger fruits.
What you're saying here is that there's no difference between possible and impossible.
They couldn't have any control because it was an observational study aka not really even worth talking about unless there is a really sensible mechanism that explains it or you're a scientist studying glaucoma who's thinking about designing a animal or human experimental trial.disgruntledgamer said:If it's not associated with other caffeine products than perhaps it's linked to something else in the coffee. Should of had a decaff control.
The reason why there isn't really a difference between GM and selective breeding is because all living things (that we know of) make their proteins and DNA out of the same building blocks.Yopaz said:So there's no difference in introducing genes that would never ever occur in in an organism and using genes already present in the organism?canadamus_prime said:We're still talking about producing plants and animals with traits we desire, so no.Yopaz said:The difference is that you strengthen genetic expression that was already present in the organism you are modifying rather than introducing a foreign gene that never required the existence of any natural occurrence of the gene.

I have studied cell biology so there's no need to treat me like I'm some ignorant kid here. We're all made of the same building blocks? Seriously?

any GM food we make could only be as different from a natural food as say two video games made in the same engine by different developers.
That is to say there is alot of potential for difference but only really to the extent that one is trying to make one.
That being said when we make a game (GMO) in the engine (DNA) we should probably test for bugs (negative health effects) but we shouldn't mistake that for being a fundamental flaw in the process it is just a possible outcome of introducing a new element into a complex system.

I don't really see your point, If I drank an human insulin solution made from e.coli and a human insulin solution made from a human pancreas they'd have the same effect on me if they were pure enough. (Not that drinking insulin makes any sense.)Yopaz said:I have studied cell biology so there's no need to treat me like I'm some ignorant kid here. We're all made of the same building blocks?

I can breed carrots for all my life, and let my children and grandchildren keep breeding them. No matter what we do, that plant will never be able to produce human insulin. It doesn't need to gene, so it will never occur in its genetic code. No matter how hard you breed, you can't force a difference the plant wouldn't be able to do in nature.
You say there is potential for a difference. Getting E. Coli to produce insulin is one of the biggest breakthroughs in dealing with IDDM and clearly an example that the difference is there.
I agree, there's no sense in drinking insulin. We get insulin by using injections.antipirate said:I don't really see your point, If I drank an human insulin solution made from e.coli and a human insulin solution made from a human pancreas they'd have the same effect on me if they were pure enough.

How about this:
I have a purple eggplant and a pink eggplant the genetic difference between the two happens to be only a single DNA nucleotide and for no reason in particular I want to turn the purple eggplant's progeny pink so I artificially modify that single nucleotide so that now I have two identical lines of eggplant that are nutritionally identical even though one was genetically modified.
That brings me back to my point: It isn't the fact that a food was genetically modified that is the problem it is the implications of the specific genetic modification that was undertaken.
Therefore any new genetic modification should be tested to see if it is safe but there isn't any broader problem than that.
You say "it will never occur", then immediately follow that up with "you can't force a difference the plant wouldn't be able to do in nature." What kind of an silliness is that?Yopaz said:I have studied cell biology so there's no need to treat me like I'm some ignorant kid here. We're all made of the same building blocks? Seriously?

"We" can't change crap with breeding. All we can do is pick which seeds go back in the soil. If we want to boost our odds a little we can pick the seeds that display the most genetic instability.Yopaz said:Now your example. Yes, we can change the colour and the size of a crop with both GMO and breeding, in this process GMO is simply faster. However the example I mentioned is impossible by breeding. Adding genes to an organism is only possible with GMO. Amplifying gene expression can be done with both.
Do you see the difference or do I need to give you an analogy fit to tell a kid?
Actually it is an impossibility for a carrot to start producing human insulin because the mechanisms around producing insulin requires extremely specific reaction mechanics. The glucose metabolism is also so widely different from plants and animals that it's out of the question. Plants store their polysaccharides as cellulose while we store them as glycogen. Insulin signals to the body that we''ll start assembling glucose molecules. There probability that a plant will change its entire physiology, and turn millions of years of years of evolution in a random mutation is about as big as me having a kid with wings that actually allows him to fly.Webb Myers said:You say "it will never occur", then immediately follow that up with "you can't force a difference the plant wouldn't be able to do in nature."

Sure, the likelihood of a spontaneous mutation producing insulin in a carrot is astronomically low. But there are about 100 Billion carrots grown EVERY YEAR. We don't test every carrot grown for insulin content, but it would not be the least bit surprising for some Ukrainian farmer to discover that the "spontaneous remission" of his diabetes was due to the carrots he grows in his garden.

"Adding genes to an organism is only possible with GMO." Yes, but WE don't have to be the ones doing the genetic modifications. Nature does trillions of genetic modifications a day without our help.
What's my point? I am genuinely pleased to see rational, scientific discussion taking place, but don't use the words "never" or "impossible" when you mean "very, very, unlikely". The universe is very, very, very, very, very, very, very, very large place, so "never" probably means "just a few dozen times this month".

The study links people who consume more than 500 mg of caffeine to glaucoma. You want to know why? It's not the caffeine; it's the dehydration from having that much in your system.
To put this in perspective:
The absolute darkest cup of coffee you can buy is 200 mg of caffeine. A Starbucks latte (which is made of soymilk and ESPRESSO) is 125 mg. We're talking about 2-5 cups of coffee depending on darkness of roast, or
To sum up--if you're drinking 500+ mg of coffee on a regular basis, glaucoma is the LEAST of your problems. I'd be more worried about heart conditions.
Even if you were drinking the 500mg per day, nothing in the abstract for that study indicated to me it's actually worth worrying about. You can see my last post if you want details, but unless the absolute risk shoots to something ridiculous like 50% from 1-2%, which is highly doubtful, it's probably not worth giving up coffee.Covarr said:"500mg or more of caffeine per day"
That's a lot. What of people who have a cup or two before work in the morning and leave it at that? I consume an average of maybe 150-200mg a day.
P.S. Thanks
