(Updated) NASA’S Big Announcement: Scientists Discover Arsenic-Based Life Form

WASHINGTON (The Blaze/AP) — Scientists have discovered a strange bacteria that can use arsenic as one of its nutrients, a discovery some speculate is the big announcement NASA is set to unveil at 2 p.m. E.T.*
The finding widens the possibilities for finding different forms of life here on Earth and possibly on other planets or moons. The unusual bacteria was found in a lake in California.
Six major elements have long been considered essential for life — carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur.
But the researchers found that the bacteria is able to continue to grow after substituting arsenic for phosphorous.
Ariel Anbar, a co-author of the report, said “it makes you wonder what else is possible.”
Earlier today, the Huffington Post published a story saying that the newly-discovered life form is NASA’s bug announcement.
“The news has leaked now,” HuffPo writes, “and while the discovery is not extraterrestrial life, NASA has indeed uncovered an entirely new life form on our planet that “doesn’t share the biological building blocks of anything currently living.”
*UPDATE from NASA:
NASA-funded astrobiology research has changed the fundamental knowledge about what comprises all known life on Earth.
Researchers conducting tests in the harsh environment of Mono Lake in California have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism substitutes arsenic for phosphorus in its cell components.
“The definition of life has just expanded,” said Ed Weiler, NASA‘s associate administrator for the Science Mission Directorate at the agency’s Headquarters in Washington. “As we pursue our efforts to seek signs of life in the solar system, we have to think more broadly, more diversely and consider life as we do not know it.”
This finding of an alternative biochemistry makeup will alter biology textbooks and expand the scope of the search for life beyond Earth. The research is published in this week’s edition of Science Express.

Posted on December 2, 2010 at 3:01pmI love how half the comments on here are about the actual article, and half is about “argh, damn progressives need to eat arsenic!”
Not bashing, but i just find it funny.
Anyways, It is actually a big find. I personally think that if we ever found any kind of extraterrestrial life that has similar intelligence to us, it would either 1) Bring every human being together, as humans would instantly think these new alien lifeforms are threats, or 2) We would continue to bicker, and the aliens would either pick a side or do away with us entirely. I could be wrong of course, but it’d be nice (or scary) to imagine.

NASA is angry at Obama for declaring that their primary objective is to help Muslims. They’re angry that Obama has cut funding declaring, “We’ve already been to the moon.” Today’s announcement by NASA is purely political. They need funding. They’re trying to restore the public trust that Obama has damaged. They want Americans to feel like NASA is deserving of the huge budget that they have so they felt like they had to report something.
This news would typically be buried in the science section of most websites. NASA called a big press conference because of the huge hits that they’ve taken politically under Obama.

I was tempted to agree with your first post on the thread, as this is quite important in the big scheme of things and I’ve said as much on the thread (as have others), then I scrolled down and saw your attacks, smears and sneering.
If you wish to not perpetuate the image of the bitter, angry leftist I strongly urge you to consider developing the capacity for true tolerance. Even if others are intolerant towards you, your example of tolerance can change minds and convert souls. Being angry and bitter does nothing but close down any chance of helping others understand.

Posted on December 2, 2010 at 2:29pmOk, I’m not a scientist so this might seem dumb. Is it possible that the bacteria started out as a carbon based lifeform and over time adapted to the environment since it was “using arsenic as one of its nutrients”? If there was mostly arsenic available wouldn’t it naturally evolve towards being an arsenic based life form?

Yes, that’s conceivable. Adaptation to the surrounding, and a dose of millions of years of “if it don‘t kill ya’, it makes ya’ stronger” and badda bing, a being that can replace phosphorus in its genetics with arsenic if required.

Most likely we’d be talking extra-solar. Extra terrestrial means that it comes from the solar system, just not earth. A distinction some weenie made to me years ago. :)
I strongly suspect anything originating in this solar system would hold a lot of common traits with life here, even if it is strangely different in many respects. The solar system coalesced out of the same basic cloud after all (elements).

Posted on December 2, 2010 at 3:20pmCouldn’t agree more Tess. I’ve been saying for as long as I can remember that scientists are foolish when they talk about how they need to find water on another planet. Life on EARTH needs(as far as we know) water to be sustainable. But what makes us think that other life would need water? Now, if they want to talk about whether WE could live and colonize somewhere, sure. But life?
The universe is so massive and diverse that life could be spawned out of almost anything. Water and the other elements in our atmosphere and air might be required for life, or they might not. I’d bet on not.

Biologists now group life into three Domains: Bacteria, Archaea, and Eukarya.
Bacteria should be obvious.
Eukarya is complex single-celled organisms and all multi-celled organisms.
Archaea is what I think you’re talking about. Mostly extremophiles, regarded as being somewhere mid-way between Bacteria and Eukarya in evolutionary terms.
However, the discovery here is that these bacteria actually incorporate arsenic as a substitute for phosphorous in their important molecules and proteins. Interesting because phosphorous is very important in membranes and DNA and in metabolism.
