Ahoy, shipmates!

Perhaps a heads-up is in order on this forum. In a bit less than 24 hours from now, there will be a news conference at the NASA Headquarters ”to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life”, ref. http://www.nasa.gov/home/hqnews/2010/nov/HQ_M10-167_Astrobiology.html.

I think I’ll see NASA television, http://www.nasa.gov/multimedia/nasatv/index.html, at 7pm UTC tomorrow Thursday night.

Speculation department seems to be available in Cafe SETI: http://setiathome.berkeley.edu/forum_thread.php?id=62142.

Get ready! Perhaps someone more cleaver has figured out how to find an ET signal in the RF haystack. Certainly, this project seems to spend more time rearranging cables and hardware than producing noteworthy results (just my impression, of course).

Perhaps, if something interesting is introduced on 12/2 we should change Seti's name to Search for Astrobiology (SAB); it might get some funding then!

Rumor Roundup: Has NASA Discovered Alien Life?

Published December 01, 2010

| FoxNews.com


A NASA press release announcing "an astrobiology finding" -- something that will impact the search for extraterrestrial life -- has sent shockwaves through the blogosphere.

So NASA can just call a news conference, with no proof, say that life exists so place else???

HMMMMMM......We know that life can exist in extreme conditions here on earth.... we want real life forms....Like us, or better ????? not pea soup life.....

Maybe this is just the litttle bay steps that the goverment will use to revel that we are not alone in the galaxy or this dimension

the truth is out there, and no body here wants to tell the truth because of religion, or politics

So Bill Barnes, of UFO Hunters, may not be a nut case after all.
Baby steps. HMMMMMMMMMMMMMMMM??? The announcement, may go with this article.

Estimated Number of Stars May Triple

Published: December 1, 2010






It really is full of stars.

Scientists said Wednesday that the number of stars in the universe had been seriously undercounted, and they estimated that there could be three times as many stars out there as had been thought.

The Sun newspaper in the UK broke the news embargo early. Now its all over the internet.

This is the news;
bacteria has been found at the bottom of Mono Lake in California's Yosemite National Park which is rich in arsenic - usually poisonous to life

Story; http://www.telegraph.co.uk/science/space/8174040/Life-as-we-dont-know-it-discovery-could-prove-existence-of-aliens.html

---------------
So they found arsenic based life in Mono lake, California. To be honest, i'm not sure just how significant that is, so we will have to wait for the NASA experts to tell us exactly why it merited such a bold press announcement. I call it hyping up a less than average science discovery. This discovery does NOT get us any closer to detecting other life in the universe.

Astro-Biology ?

It will probably be one of these:

Evidence of ammonia or other precursor componds to amino acid formation found floating in a gas cloud.

Wobble of a star that suggests a planet that might be in the temperate zone for supporting life.

Fossils of bacilli or other primitive life found in a meterite.


I would be pleased if it were more electrifying than these.

I've been reading widely about the subject of today's NASA press conference; speculation, journalistic leaks, and inferences based on those scientists participating, and their current work. It seems possible that an earlier line of life on Earth, wholly independent from ours, has been discovered at California's Mono Lake. Arsenic would replace the functions of chemically similar phosphorus. Phosphorus is widely used in all previously known life, from DNA and RNA to ATP (adenosine triphosphate, used in energy transport in cells) and phospholipids, which make up cell membranes. A substitution of all these molecules with arsenic-based alternatives would produce something very strange indeed, essentially an 'alien', older, independent form of life, right here on Earth.

Arsenic based life forms! I look forward to the press conference to explain the details, but this IMO is a major step forward in Biology. It also lends some weight to the argument that some astrobiologists insist life doesn't have to be based on the perceived building blocks of known life (carbon, nitrogen, hydrogen, oxygen, sulphur and phosphorus), expanding the chances of life elsewhere by enormous amounts!

I read about this announcement on the online mag The Register the bacterium in question is related to E-coli and is capable of using both Arsenic and Phosphorus now I'm of to NASA web site to see what all the excitement was about.

As it turns out, the bacteria concerned is of a known type (G F A J-1), a holomonodaceae proteobacteria. This seems to argue against the much-repeated talk of a separate 'tree of life'. Dr. Wolfe-Simon's work *does* appear to expand the range of chemicals that life can employ, and thus the range of environments in which it can occur. It indicates that elements currently thought essential to life may not be. The possibility is raised that life may admit of *other* elemental substitutions. Generally speaking, life looks even likelier to occur throughout the universe than it did yesterday. Michael

With half cryptic fashion Nasa just admited that life exist every possible corners of universe. With that basis if oxygen based bacterias manage to achieve mammal level of complexity then arsenic or anything based bacterias very likely should achieve their level of "mammals" within same time frame of 0.5 billion years or little more.

Even some decade old documentary showed that biologists were discovering bacterias in volcano acid rivers deep inside underground caves.

The arsenic tolerant bugs NASA publicity is getting a rather harsh review from fellow scientists:

Microbe gets toxic response

Days after an announcement that a strain of bacteria can apparently use arsenic in place of phosphorous to build its DNA and other biomolecules — an ability unknown in any other organism — some scientists are questioning the finding and taking issue with how it was communicated to non-specialists. ...

But data in the paper, they argue, suggest that it is just as likely that the microbe isn't using the arsenic, but instead is scavenging every possible phosphate molecule while fighting off arsenic toxicity. The claim at a NASA press briefing that the bacterium represents a new chemistry of life is at best premature, they say.

"It's a great story about adaptation, but it's not ET," ...



On the parallel topic of life here on Earth, if only the Climate Deniers could see how quickly scientific reviews question anything questionable...
