Skip to comments.Nasa raises hopes of finding extra-terrestrials, discovery of 'alien' bacteria, survives in arsenic

Incredible microbe found in California lake
Nasa scientists are set to announce that bacteria have been discovered that can survive in arsenic, an element previously thought too toxic to support life, it can be revealed.
In a press conference scheduled for tomorrow evening, researchers will unveil the discovery of the incredible microbe - which substitutes arsenic for phosphorus to sustain its growth - in a lake in California.
The remarkable discovery raises the prospect that life could exist on other planets which do not have phosphorus in the atmosphere, which had previously been thought vital for life to begin.
But it will come as a major disappointment for those who had hoped Nasa was about to announce that it had found life on other planets.
Nasa sparked alien hysteria around the world with its announcement of a major press conference to be held tomorrow.
It induced feverish debate as to whether scientists were about to announce that they had discovered life on other worlds.
But after The Sun broke the embargo on the story this morning, it can be revealed that the truth is rather closer to home.

Interesting, but then they discovered nothing elsewhere, just that some Earth bacteria can live in arsenic.
I’m pretty sure I’ve smelled the odor of that bacteria on a New York City subway.
Oh no, here's comes the Title Police!
LibWhacker, you are hearby charged with violation of Chapter LXIV, Verse XLII of the Free Republic Posting Code:
Your sentence commences now.
What is interesting is that there is life on earth that is totally unrelated (no evolutionary conection).
This discovery seems to be another example.
How many completely different types of bacteria are there?
To me, that greatly reduces the possibility of evolution as an explanation for the origin of life....
Totally unrelated? Got a citation for that?
Every living organism uses the “Universal Code” or a slight variation of it, that ‘translates’ DNA “genes” into the Amino Acid sequence of a functioning protein molecular machine.
Moreover every living species has similar variations of the same ubiquitous “housekeeping” genes that perform essential cellular functions.
I wish they had said something about its DNA. Is its DNA unrelated to anything else seen on Earth? I’m guessing not. That’s why ‘alien’ was in quotes.
NASA desperately trying to validate its existence to Evolutionists.
But bacteria are not the stuff of alien fantasies.
The Lord’s works are truly miraculous.
I call dibs on all the arsenic planets.
Clearly this article was written without a clue. To wit: “... do not have phosphorus in the atmosphere.”
Yeppers, who knew that *gaseous* phosphorous (or compounds thereof) has LONG been a recognized prerequisite for life?!?!
Hmmm. Let me think back to 9th grade biology. Nope. 10th grade chemistry? Nope.
Geesh. Where do they get these writers?
Here are some generally accepted facts: The phosphorus cycle differs from many other biogeochemical cycles because it does *NOT* involve the atmosphere in any significant way. Phosphorus and phosphorus-based compounds are usually solids at normal temperatures and pressuresfound on Earth, and any phosphorus in the atmosphere is usually only present in the form of dust particles.
Phosphorus - which is an essential nutrient - is usually found in the form of the phosphate ions (PO43- and HPO42-). It is an important component of nucleic acid molecules (DNA & RNA) and of the cellular energy carrier ATP. Phosphorus is also an important building block of bones and teeth, where it is found in the form of calcium phosphate.
Most phosphates originate as salts in ocean sediments or in rocks. Over time, geological uplift brings these sediments to the surface, and weathering releases the phosphate ions. Plants can then absorb these phosphates from the soil and use it in cellular processes. Phosphate taken up by plants may then be passed on to animals when the plant is consumed by herbivore that, in turn, may be consumed by carnivores. After death, the animal or plant decays, and the phosphates are returned to the soil by way of bacterial decomposition. Runoff from the land may carry leached phosphate back to the ocean, where it eventually enters sediments and is reincorporated into rock.
BTW, I did not bother to read the entire article posted here.
I'm pretty sure they do not know the answer to that. Saw something a while back that said biologists estimate the weight of all the bacteria in the earth's crust (i.e., living in solid rock, for the most part) is greater than the total weight of all the life forms living on the surface and in the oceans.
They were wrong about bacteria not being able to survive in arsenic. This has nothing to do with extra-terrestrials in any way.
This should not raise any hopes of finding any extra-terrestrials. If there are life forms on other planets, they will likely be in a form that we don’t even recognize as life.
But how will this help build up the muslims self-image????
I would guess that anything that thrives in arsenic is fairly strong.
This is a good find, and expands the possibility of discovering life in places we never would have considered looking at.
Archebacteria is a good example of an unrelated class of life.
It has a sulfur electron transport system, instead of oxygen, and is therefore unrelated to all life with an oxygen based electron transport system.
This bacteria lives at deep ocean volcanic vents. I studied it for a bit.
Are anoxyic bacteria that don't use oxygen at all (and find it quite toxic) unrelated at all to aerobic bacteria? Not according to anybody I have ever read on the subject.
Citation please, and can you address the universal DNA code and variants of the same ubiquitous “housekeeping” genes that are present with variation in ALL living species found upon the Earth?
“Archaea are members of the domain Prokarya and are in a kingdom of their own: Archaea” - first summary point of Link:
Where I tend to differ in my thinking from what is illustrated at the link - is that there was one “original cell.”
In any case it cleary shows that archaebacteria are very different - and deserve their own Kingdom of life.
NASA now has an entire bureaucracy dedicated to the field of astrobiology, but it’s main mission is to make the Islamic world feel good about itself. See http://astrobiology.nasa.gov/.
Your tax dollars at work.
Wrong link on earlier post. It should be to NASA Astrobiology Institute (NAI).
Very different is not uniquely different and unrelated.
A different Kingdom, but like Plants and Animals, they share the same “Universal Code” that translates DNA genes into functional molecular machine proteins, and have the same ubiquitous “housekeeping” genes.
Now the genes that they share in common have more (mostly) superficial differences that accumulate, but they share genes in common with all other living things on Earth. The most parsimonious explanation for this is they once shared common ancestry.
The “original cell” idea is pretty much discarded. LUCA - the last universal common ancestor is no longer thought of as a particular species or type of cell, but a community of slightly different cellular organisms that swapped genes with each other.
So, allow me to expand on ‘very different.’
Archaea are at least as biologically different from bacteria as you are from a coconut tree.
Have a nice day.
Just what we need — alien invaders who can’t be poisoned.
You as well.
Maybe I’m narrow minded, but if you can’t talk to it, pet it, or at least watch it running around, I’m not sure finding microbial life elsewhere is going to ring my bell.
OK, it will be a huge deal but some bacteria swimming in arsenic well, it only goes so far.
Here’s NASA’s “big story” about extraterrestrial life.
NASA breathlessly announces they’ve found life on Earth!
I knew it was a trump. Look that word up. All the PR bluster of a big announcement. Stirring up the old black magic UFO fever!
An interesting announcement stunk up by the faux fanfare.
Yeah, it's just another NASA hype, as you said it would be.

My answer is that, if they can do so, they can dispel, at least partially (if only in their own minds), the notion that Earth was uniquely created.
One small example of this special creation is the totally unique angularity between the Earth, Sun and Moon, which results in phenomena that occur during lunar and solar eclipses (or is it eclipsi?) that cannot be observed anywhere else in the universe.
