Bacteria @ 41km

Makarand writes " According to this article in The Times of India, air samples collected using balloon-borne cryosamplers at altitudes of around 25 miles contained bacteria that are believed extra terrestrial. This was revealed recently by legendary Indian astrophysicist Jayant Narlikar, who supervised the experiments last year. The article throws light on the brilliant Indian efforts to find if there is anyone out there. Here is an older article announcing the launch of this project. "

sounds dubious

[tps12]

If I collected stuff with a balloon, I'd probably hold off on assuming its extra-terrestriality. Unless it's some kind of super space balloon, but I don't think we have those yet.

And what's with the repeated mention of the guy's Indian-ness? Can we try to keep the nationalism out of Science, please? (Oh, wait, I guess that would be "multiculturalism," since he's swarthy.) And what's with calling him "legendary?" That sounds almost like WWF (or whatever it's called these days).

In any case, this sounds like only so much limelight-grabbing. I'm placing my bet now on peer review punching a hole in this guy's metaphorical balloon.

Personally, I think it's a response to the general anti-Indian bashing that Indians apparently face on most international newsgroups. Add the fact that India is only now coming out of its socialist hibernation and you have a perfect situation for some oh-I'm-so-Indian chest beating. (Disclaimer:That's not a troll. I might have something in common with Indians.)

But you're right; I agree that's a tad too gooey. Science is beyond nationalism and even (presumed) patriotism.

As for the experiment, I've read about this before. Andromeda Strain anyone? :-D

True, but this article only gives more ammunition to the anti-Indian bashers. I wouldn't want to be associated with this guy:

a) He's not the first person to make this claim about extraterrestrial microbes.

b) This isn't good science. What, he sticks a balloon above some theoretical "barrier" in the atmosphere, finds some microbes, and then claims they MUST be extraterrestrial? That's a silly claim.

I agree: dubious seems to be the correct attitude for now. The authors have a manuscript on line, linked from the Indians' UK collaborators at Cardiff Centre for Astrobiology but I can't find any indication any of this has been published in a peer reviewed journal. The evidence in the mss is:

1) some electron micrographs showing some clumpy things (putatively cells) and

2) the fact that some clumpy things in their samples can be dyed with flourscent dyes that stain the membranes of viable Earth bacteria.

While I might accept this as weak evidence there are some unknown organisms at high altitude, it is far from proving they are extraterrestial! Besides, why do they assume that an extraterrestial organism would have the same type of cell membrane as an Earth bacterial cell?

Let me get this straight...

[BigChigger]

These bacteria are 41km from Earth, a bazillion light years from somewhere else, thus, they are from somewhere else.

good logic.

No explanation != Amazing Discovery

[helix400]

Here is the text of the article explaining what was found:

The probes sucked air at four different heights. Some bacteria were found in the air samples. These were not common contaminants.

Nor had they been used in the laboratory where the test was held. Moreover, no such growth was found on control membranes.

Now how in the world does this mean its extraterrestial?

DNA?

[BCGlorfindel]

I wonder, does this "extraterrestrial" life have DNA in it? If it does shouldn't that raise a few questions? Like perhaps contamination from terrestrial sources? Attention grabbing headlines like this are rather unscientific if they are so premature as to not even do basic tests.

Extraordinary claims...

[stefanlasiewski]

Extraordinary claims require extraordinary evidence.

Which is more likely: That bacteria from Earth managed to travel 41km into the sky sometime in the last 4.5 billion years, and then survived in that environment; or that bacteria travelled millions-trillions of miles through space from some other system and just happened to find Earths atmosphere?

Hey, I like the "intergalactic spores" theory as much as anybody, but I think this scientist is ignoring the obvious.

Bacteria already found in clouds

[TheLink]

There's already plenty of existing evidence of bacteria in clouds, why do they think it's extraterrestial?

Makes me wonder why the astrophysicist is called legendary.
