NASA discovers new life

[dice]

...but I, and probably the rest of the scientific world, did not expect it to be some Earthly discovery.

I like how you just lumped yourself in with the scientific community. I bet you're the leading authority on chillaxin' in Under Armor.

 

Arsenic based life? Interesting.

Yeah...I saw what I did but was too lazy to change it. Either way, I might as well be a f*cking genius because the idiots around here screaming "Its a wikileaks diversion!!!" are probably the most retarded people I have ever seen grace the forum.

I see my post is really getting on your nerves, hence I'm the only one who mentioned wikileaks. I'm terribly sorry if I look like an idiot in your eyes, I'll try harder next time to meet your standards.

The wikileaks shenanigans weren't just known yesterday, the owner threatened to leak documents for months, like you said for Nasa announcing this weeks ago. Also note I'm not a conspiracy freak, I guess it was just a coincidance and do not believe in big brother and other crap, but I do know that life isn't fair and there are stuff covered from the public for a reason.

The one thing I really don't get is that why couldn't those bacteria just addapted to the high levels or arsen in the water.

Wow. You sir just brought a whole new level of stupid to the internet.

We share a common ancestor with this organism. If we didn't, the story would be be a lot bigger.

That's the thing, though. We don't know. With everything else we could tell, using common elements in RNA or DNA. With this stuff, we can't be certain of it.

I don't understand how we don't know. The text says they are a member of a common group of bacteria. This only gets interesting when the bacteria incorporated arsenic when deprived of phosphorus. So in "normal" conditions, they are just like any regular arsenic-tolerating bacteria.

If it was like that, it wouldn't be so damn important.

Take biology textbook. Drive corner into eye socket until a consistency of jam is reached. Use remaining eye to read biology textbook.

 

 

 

 

....I know, I know, Tetsuo beat me to the punch.

You could also say DNA or just call it NA since we don't have any other NAs in our cells than D- and RNA, K^2, since both, mRNA and tRNA are only part of the PBS and basicly are the same as a single DNA string with only one differnce: every thymidin on the DNA is translated into a uracil molecule while the transscription is running since otherwise the ribosoms woulnd't be able to handle with the mRNA since they don't 'know how to' handle with tymidin at all.

But PH is a standard element of each nucleotid and it also appears in huge amount as ATP which is needed during the replication. But this is the first lifeform which does not need PH to duplicate its DNA in anyway but uses arsenic instead. Actualy you can say its like your classmate drinks mercury instead of water to survive since his body can handle with it. Its a bit exegerated but its a similiar system.

Hmm.

GNA is not known to occur naturally.

hmmmm

don't even try it with LNA, its a modified peptid of the RNA

I know what I'm talking about

Just because something is synthetic doesn't mean it should be disregarded. It's like the transuranium elements.

Point is, it's more accurate, especially considering the synthetic ones.

You're kidding right?

I don't see any connection between synthetic NAs and what was this post about then? I'll make sure you will understand it:

 

 

...since we don't have any other NAs in our cells than D- and RNA...

 

Got it?

NASA didn't discover anything. They only funded this. This microbiologist found it, and it doesn't seem like entirely new life. It's part of a family of bacteria that we already knew existed. The scientist discovered a variant of it that manages to substitute arsenic for phosphorus.

Again. It's phosphorus we are talking about. Substituting arsenic for phosphorus is almost as fundamental as substituting silicon for carbon. It's a completely different life form.

It's not, the article was bullsh*t essentially.
