NASA Finds New Life
Damn it, I thought I was going to read that Nasa found aliens living on another planet.
Same here. But hey, new life, that's at least something.
Don't let your own misconceptions about what the revelation "should" have been. This is one of the single greatest scientific discoveries in our recorded history. We have a life form on our own planet that exists without the components found in all other life on the planet.
Of the hundreds of millions of different life forms on this planet, this is the only one that is genetically unrelated in any way. Crazy.
Wow, they were right in the movie Evolution!
At least we know we just need a little selenium to kill them if they try to take over.
So correct me if I'm wrong, but this bacteria could be from another planet, right?
What else could explain it? Could it be a newly created life form, or has it sat in that lake (and that lake only) since the beginning of time?
I guess we'll find out at the conference, which is about an hour away.
Oh SWEET. That's pretty cool.
Perhaps from a meteor?
I hope it gets super powers from earths yellow sun!
Funny thing is I was watching a documentary a week ago about a scientist who was looking for 'alien' DNA on earth, while her friend/colleague was busy with the space project looking for 'known' DNA on Mars, and she was going to Mono Lake and try to find it, because the odds would probably be the highest.
I know this is supposedly a big scientific deal: it's the first organism we've ever found that does not share the DNA all other lifeforms share. Still, I can't help but feel it's not that super big a deal..after all, the difference in this organism's DNA is that it replaced one toxic materal, fosfor, with another one, arsenicum, that on some levels looks alot like fosfor.
This still doesn't really say anything about how in space, or on our planet, there could be organisms made of fully different materials..this organism still sort of tried to play by 'the rules' but found a replacing part. In short: next time we are looking for life on other planets, we could still very much encounter organisms but not know it because we're still searching 'too close to home'.
I don't want to piss all over the scientists..it's great work and we wouldn't be as advanced as we are without science, but consider me a bit underwhelmed.
I guess it's possible the organism is sort of 'new', but maybe it was able to live more freely in the past? It's been suggested that the air just had higher concentrates of arsenicum during Napoleon's time(so he wasn't killed being poisoned by it), so maybe the organism evolved in a similar time, but eventually had to settle for the only place on Earth where it was still possible to sustain itself? I know nothing about this...
As much as omg alien crash sounds totally awesome, I wouldn't bet on it.
There is currently no evidence to indicate this bacteria did not develop naturally on earth, so there really isn't any reason to say it came from a meteor or whatever. What this discovery DOES show is that there is a wider range of conditions than previously thought under which life can develop, and the actual forms of life that have been observed to exist are now expanded. This means it just became somewhat more likely that life of some kind exists elsewhere in the universe, even if none has been observed at this time.
Agreed, so mind boggling it hurts.
Can someone change the thread title to "NASA discovers new form of life on Earth?" this title seems a bit misleading
But other than that this is incredible! This is why I love science!
I'd love to study Astrobiology one day.
This also means the science textbooks in my school are even more outdated than previously thought.
Hell, I'd love to study Quantum Mechanics but the math would kill me 10 times over! LOL!
cool. a arsenic based life form.
time for a horror movie. any takers?
This is pretty damn major. All these tests carried out for bacterial life on mars (even on the moon) would have to be repeated with a wider spectrum in order to be certain, and even then - the mere existence of this lifeform proves that there could be many different bases for organic life - maybe even on spectrums undetectable to humans at our level of development.
It seems like such a really tiny thing (especially backed by the initial reaction I had of "Oh, it's not even alien.") - but in reality the implications are collosal. :O
Apparently this whole thing isn't quite as spectacular as we thought.

They're part of the same evolutionary tree as we are. They're unique, but they're not alien to this planet or the life on it.
Yeah, see, I've always considered aliens to be life from other planets. Life that originates from Earth, no matter what it's made from, doesn't classify as aliens to me. Sure it's cool that it's different and new and unusual, but not life on other planets material.
Blue Gender, and so it begins....
I always suspected that our definition of a life form couldn't be just one thing.
