    Re: NASA Discovers New Life: Arsenic Bacteria With DNA Completely Alien To What We Kn

    It finally answers the long-standing question of whether life has to be "life as we know it," or if other forms of life are possible.

    In response to the OP this is no surprise and I thought we covered it pretty well yesterday when NASA was making out like they were going to make an earth shattering announcement, that now we know was all hype.

    If you do a little research you will find that there have been as many as over 16,500 discoveries of new life forms in a single year.

    As time goes on we should discover even more and very strange ones as well.

    I believe life is abundant though out the Universe and one day either the Government will announce they have proof of life on another planet, or intelligent life will present itself here with the following:

    Much better than the remake.

    Re: NASA to announce "major discovery" that could boost chances of life on other worl

    Here's Wired Magazine / Gizmodo's take on it:
    NASA Finds New Life Form | Wired Science | Wired.com

    Hours before its special news conference today, the cat is out of the bag: NASA has discovered a completely new life form that doesn’t share the biological building blocks of anything currently living on planet Earth. This changes everything.

    gizmodo_logoAt its conference today, NASA scientist Felisa Wolfe Simon will announce that NASA has found a bacteria whose DNA is completely alien to what we know today. Instead of using phosphorus, the bacteria uses arsenic. All life on Earth is made of six components: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. Every being, from the smallest amoeba to the largest whale, shares the same life stream. Our DNA blocks are all the same.

    But not this one.

    Uhh this is a pretty major discovery. It's the first time "life as we don't know it" has been found, and strongly suggests that we may be overlooking worlds that could potentially harbor life if we just assume that all life shares our biochemistry.

    This isn't just a random new species with an interesting quirk. It's a completely different TYPE of life, with a biochemistry completely different from life as we've known it.

    Just don't try and have sex with an arsenic based life form. It could be fatal!

    Maybe you should actually learn what "hard science" means before saying you're in favor of it. Anyway, a pretty huge discovery and well worth the "hype" for those that actually understand such things. The importance for NASA is pretty obvious and well explained as to why they would be involved in this kind of research. No need to get into the obvious, I think.

    Yeah, this isn't like finding a new species.

    EVERY species ever found on earth share the same 6 common building blocks in DNA, including the 16,500 new species you spoke about being found last year and every single one that came before them.

    This isn't a new species, its essentially a new form of LIFE. Its fundamentally different on a molecular level than every other living entity on the planet.

    Re: Nasa to make announcement about possible ET life find on Thursday

    NASA successfully found a species of bacteria that has replaced the phosphorous backbone in its RNA with arsenic, and the bacteria remained fully functional. This has huge potential for life on other planets.

    Searching for life on earth that challenges our preconceived notions of how life can operate is essential to understanding the potential for other life in astrobiology. NASA has a huge amount of resources dedicated to visiting the most extreme places on earth in search of life.

    A good example that I recently watched a documentary about is the Crystal Cave: YouTube - Naica Crystal Cave - Mexico 1/5

    This NYT story gives a rather different account; according to this, it's a bacterium which was fed arsenic and swapped out phosphorous for it.

    Which, of course, is still significant, but they apparently didn't discover it that way.

    Re: NASA Discovers New Life: Arsenic Bacteria With DNA Completely Alien To What We Kn

    They made it a point to stress right off the bat with the press conference that the bacteria substituted arsenic for phosphorous in its DNA, it is not a new form of life it is an adaptation of existing life. It does still have profound implications though, since it illustrates that life can exist in conditions previously thought hostile to it.

    I want to find more info and a detailed written account of their findings, to find out when this substitution took place, was it in the lab or prior.. this is still unclear, and I do not have the time to spare atm to really dig deeply into it -if anyone can come up with details (not journalist interpretations please) that would be great.
