“NASA will hold a news conference at 2 p.m. EST (11am PST) on Thursday, Dec. 2, to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life. Astrobiology is the study of the origin, evolution, distribution and future of life in the universe.” Watch it HERE live.
NASA Watch blog theorizes it is "Arsenic-based biochemistry" regarding "the implications for the origin of life on Earth, how it may have happened more than once on our planet, and the implications for life arising elsewhere in the universe." Noting that "NASA has not found life on any other world."
Astrobiology Magazine goes a little further to discuss potential "Slime Worlds"
Other theories are being spread that "they've discovered arsenic on Titan and maybe even detected chemical evidence of bacteria utilizing it for photosynthesis..."
I myself am hoping for something supermassively larger, perhaps a planet eating sentient ala Galactus...

Anticipating the news, I think, is mostly just a form of entertainment. TV presenters discovered this long ago, and now it's everywhere -- SOON we're going to show you SOMETHING just works as a media strategy.
But from the point of view of gaining knowledge, the real stuff, well, I'd just as soon wait till 2pm. (And probs so could this post?)
Hype almost always leads to disappointment, after all, because the hypers know that their work won't really be checked.

I read the post as NSA being the agency involved instead of NASA, which didn't correct itself in my brain until I clicked the link to the thread. I was thinking this is it, we're gonna meet aliens now, and given who is announcing it there is a good chance this won't be a pleasant announcement. The NSA is going to reveal itself as doing something far beyond what most people imagined an intel agency would do, and it's so obvious the most secretive branch of our intelligence services be involved with this kind of thing.
Except they weren't.
OK, so back to the boring truth ... what is it the aliens are made out of now? Asbestos? Absinthe?
Is the punchline that the aliens are us? Or that soylent green is people? That would be a problem, because it's so very delicious and born with original sin ...

That word should have new meaning for all of us today. We can't be consumed by our petty differences anymore. We will be united in our common interests. Perhaps it's fate that today is the Fourth of July, and you will once again be fighting for our freedom… Not from tyranny, oppression, or persecution… but from annihilation. We're fighting for our right to live. To exist. And should we win the day, the Fourth of July will no longer be known as an American holiday, but as the day when the world declared in one voice: We will not go quietly into the night! We will not vanish without a fight! We're going to live on! We're going to survive! Today we celebrate our Independence Day!

Here's a writeup of what the announcement is set to be about.
I should say it's rather more exciting than simply finding extremophile bacteria. This appears to mean that the phrase "life as we know it" means something different now than it did previously. Sure, it's only bacteria, and it's on Earth, but there it is.

The total number of stars in the Universe "is likely three times bigger than realized." Yale University astronomer Pieter van Dokkum says there are "possibly trillions of Earths orbiting these stars," dramatically increasing the possibility of finding alien civilizations.OK, so we've found a huge new amount of mass in the universe, yeah? So... How much does this reduce the need for Dark Matter? What does this tell us about such things? Is it miniscule compared to the amount of Dark Matter we hypothesize or does it take a big chunk out of the missing matter or even completely eliminate it???

Link to the Nature.com article for the extremely lazy.
Felisa Wolfe-Simon, a geomicrobiologist and NASA Astrobiology Research Fellow based at the US Geological Survey in Menlo Park, California, and her colleagues report online today in Science that a member of the Halomonadaceae family of proteobacteria can use arsenic in place of phosphorus.posted by statolith at 9:55 AM on December 2, 2010 [1 favorite]
Color me not disappointed. If the arsenic information is accurate, this is really huge. Up to today, we had evidence for only one chemical basis for life. Now we have two data points, which makes it hard to avoid the conclusion that life has the ability to harness a great variety of building blocks for its seamy, self-perpetuating purposes. Like so many discoveries in the history of astronomy and cosmology, we once again discover that we have overestimated our privileged place in the universe, and that far more is possible than we've previously dreamt of in our philosophy. Couple this with the news from the other day about how we've underestimated the number of stars by 3x, and it's been quite a week.

NASA needs more funding. We're not going to find aliens by sifting through terrestrial lakes or spying with telescopes. Everybody knows the way to do it is to build a great big rocket ship, go to another planet with the intent to obtain phlebotinum, and then be surprised.
Hopefully the alien surprise will be wacky fun, and not gruesome carnage. Either way though, we need rocket ships. Sleek 1950s ones with fins.

Hopefully the alien surprise will be wacky fun, and not gruesome carnage. Either way though, we need rocket ships. Sleek 1950s ones with fins.

They're not aliens. They're Arsenic-Americans.
And, I should note, they were here before the white man.

I'm confused. It's way past the conference time, and I have been flying down the Highway of Tears, listening to CBC radio all day with bated breath, but nary a peep. So what new, incredibly momentous, Stop The Presses! you must hear this! thing actually happened?

PareiodoliaticBoy: What they found is a species of bacteria living in Mona Lake that uses arsenic in its backbone instead of phosphorous. They alo claimed that it was Life without phosphorous.
This finding was actually covered by Through the Wormhole earlier this summer, and NASA's press conference was mostly confirmation.
The question that wasn't answered explicitly is whether this bacteria is a member of our domain of life that's just using a chemical hack to keep its DNA stable in an extreme environment, or wether this bateria has NO phosphorous in its metabolism at all. The latter would suggest that it's from a completely separate domain, outside our tree.
That would make it as alien to us as bug eyed monsters from Zeta Zeticuli. Obviously NASA needs another decade of funding to figure this out.

er, sorry, the Through the Wormhole episode should link here. It's also a lot more watchable than that segment of the NASA press conference, which features the same biologist, but painfully unedited.

clarknova: This summary says that the bacteria are probably descended from the same phosphorus-using cells we are:
Astrobiologists found the arsenic-based bacteria while looking for a possible "second genesis" of life on Earth. […] Last year study leader Felisa Wolfe-Simon of NASA's Astrobiology Institute published a paper suggesting that one possible version of Life 2.0 would be a creature that chemically substitutes arsenic for phosphorus.posted by hattifattener at 7:37 PM on December 2, 2010
[…]
Despite their oddity, however, [the GFAJ-1 strain found in Mono Lake] are genetically too similar to ordinary life to truly be descendents of a second genesis. "This is not Life 2.0," Davies said.
So the microbes survived with no phosphorus in high levels of arsenic. The small amounts of phosphorus naturally found in the DNA is replaced by arsenic. Nothing like that has existed until now. They are not found in nature, this was done in a lab, though the microbes originally came from an arsenic rich lake. None of this has really been proven to a point or evaluated by other scientists yet. And we were told about it an irritating, overly narrative, and pretentious way by the lady scientist.

As I said, none of this is even mildly surprising. As for the incredibly over the top analogy that this would be like KENNEDY'S ASSASSINATION, this is nothing like that, actually. It`s more like my sister announcing that her 1970 Barbie Dream House is fetching 12% more on EBay than when she bought it.

Lots of skepticism at that Guardian tracker page Rhomboid linked above. Steven Benner is getting quoted a lot:
But Steven Benner, a distinguished fellow at the Foundation for Applied Molecular Evolution in Gainesville, Fla., remains skeptical. If you "replace all the phosphates by arsenates," in the backbone of DNA, he said, "every bond in that chain is going to hydrolyze [react with water and fall apart] with a half-life on the order of minutes, say 10 minutes." So "if there is an arsenate equivalent of DNA in that bug, it has to be seriously stabilized" by some as-yet-unknown mechanism, Benner said.
and
"I do not see any simple explanation for the reported results that is broadly consistent with other information well known to chemistry," he says....Benner didn’t dismiss the experiment out of hand, though, saying that it would be straightforward to do more tests on the alleged arsenic-DNA molecules to see if that’s what they really are.

Anything can be a poison given the right conditions. What we do know for sure is that life is ubiquitous. There are undoubtedly life forms that we won't ever be able to comprehend or perceive. For all we know the colour blue is a life form. Perhaps the universe is a life form, as any pot-smoker can testify. It's pretty much a given that other life forms throughout the universe will be based on entirely different processes from the ones which we know. That scientists have shown one other possibility is neither surprising, nor worthy of such breathless histrionics. Interesting? Sure, but hardly world-shattering; which is why this announcement of old research didn't even make the CBC news.

Glad you're so amused Marisa. The story finally hit CBC's Quirks and Quarks today. Dr. Oremland's analysis is that science fiction speculation has yet again shown to be more aligned with reality than established scientific dogma, and that this experiment clearly opens the door to the long-mooted possibility that the chemical basis for life will likely be far more broadly based than our current limited understand has shown. He also comments on poisons and toxicity, and how these concepts are, in fact, relative. While conservatively almost - yet not quite - dismissing the long-standing SF idea of silicon-based life forms, he does conject that Selenium might be the next candidate for this kind of experiment.
Scientists have always wondered, though, if it might be possible to have life based on a different set of chemicals, either here on Earth or possibly "out there." And the answer, as of this week, seems to be yes.
As suggested, the takeaway for this is that internet rumour-mongers were hauling in a half-filled net. Neither Dr. Oremland, nor anyone at the steady CBC, was even close to being overboard enough to liken the significance of this to the Kennedy assassination. The broadcast can be listened to here.

Rosie Redfield at the University of British Columbia wrote a critical review of this paper. Her conclusion:
Bottom line: Lots of flim-flam, but very little reliable information. The mass spec measurements may be very well done (I lack expertise here), but their value is severely compromised by the poor quality of the inputs. If this data was presented by a PhD student at their committee meeting, I'd send them back to the bench to do more cleanup and controls...posted by grouse at 8:14 AM on December 5, 2010 [1 favorite]
I don't know whether the authors are just bad scientists or whether they're unscrupulously pushing NASA's 'There's life in outer space!' agenda. I hesitate to blame the reviewers, as their objections are likely to have been overruled by Science's editors in their eagerness to score such a high-impact publication.
Alex Bradley at Harvard contributes his analysis of this finding:

A story in Slate: "This Paper Should Not Have Been Published"
Nature: "Researchers question the science behind last week's revelation of arsenic-based life."
Nature: "Researchers question the science behind last week's revelation of arsenic-based life."
Felisa Wolfe-Simon, a NASA astrobiology research fellow at the US Geological Survey in Menlo Park, California, and the study's lead author, refused to address criticisms. "We are not going to engage in this sort of discussion," she wrote in an e-mail to Nature. "Any discourse will have to be peer-reviewed in the same manner as our paper was, and go through a vetting process so that all discussion is properly moderated."posted by grouse at 10:10 AM on December 7, 2010 [1 favorite]
But Jonathan Eisen, a microbiologist at the University of California, Davis, calls this "ludicrous", after a NASA press release drew media attention with claims of an "astrobiology finding that will impact the search for evidence of extraterrestrial life", a theme that Wolfe-Simon echoed at the briefing. "It is absurd for them to say that they are only going have the discussion in the scientific literature, when they started it," he says.
A comment by the author of the Slate article:
The authors of the paper declined my invitations to address their scientific critics in my Slate article, saying that such an exchange should only take place in a peer-reviewed journal. This afternoon, one of them, Ron Ormeland, gave a lecture at the Carnegie Institution, streamed live on NASA’s web site, in which he explicitly referred to exactly the criticisms raised by the people I wrote about. And then, after his talk, he fielded questions from Carnegie scientists, who asked exactly the same kinds of questions raised by the scientists in my article.posted by grouse at 2:50 PM on December 7, 2010
