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. "

    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?

  5. Re:What's their budget? by greenhide · · Score: 2

    NASA does have a low budget for a agency, but you have to consider just how many people it actually serves with those dollars. While you could technically argue, "all of humanity", so far tests in space have not, in my mind, led to any huge improvements in human life. Before I get flamed to pieces, I just want to point out that while NASA certainly is doing a lot of good, the Department of Education has a more immediate and obvious positive (hopefully!) effect on the nation as a whole, and it serves millions and millions of children. Its budget is only 56 billion dollars, about 4 times as much as NASA's.

    14 billion dollars is a lot of money. I believe that NASA deserves it, even if sometimes it seems that they sometimes do experiments in space just for the hell of it or for publicity. However, I also think that the size of their current budget is about right.

      Of course it raises questions. These issues are probably being investigated. Scientists cannot wait until they "know everything" because we will never know everything. Note that this is something he said during a presentation. Scientists often conversationally give a glimpse of recent results, especially if they might spark interest. It's not premature at all.

      Note also that this is a newspaper article, not a scientific article, thus all of the attention-grabbing language. The article's author was only reporting on one bit of a presentation. What probably happened in this case (and generally in cases where the press blows something out of proportion, though they didn't do it here) was that he said something like this: "We took great precautions to avoid contamination. The results imply that the bacteria were extraterrestrial. Studies of these bacteria will yield more information." And so on.

      Be sure that you consider the source before making quick judgements. And remember that newspaper article reports of new scientific issues are often written by people who don't understand the topic. Due to space limitations, they never give you all of the details, and often get those that they include wrong. i.e. Grain of salt.

    Extraordinary claims require extraordinary evidence.

    New Evidence Of Living Bacteria From Space
    Cardiff - July 29, 2001

    Claims of evidence of living bacterial cells entering the Earth's upper atmosphere from space has come from a joint project involving Indian and UK scientists.

    The first positive identification of extraterrestrial microbial life will be reported on Sunday, 29 July 2001 at the Astrobiology session of the 46th Annual SPIE meeting in San Diego, USA by Professor Chandra Wickramasinghe of Cardiff University. He will speak on behalf of an international team led by Professor Jayant Narlikar, Director of the Inter-Universities Centre for Astronomy and Astrophysics in Pune, India.

    Samples of stratospheric air were collected on 21 January 2001 under the most stringent aseptic conditions by Indian scientists using the Indian Space Research Organisation's (ISRO) cryogenic sampler payload flown on balloons from the Tata Institute Balloon Launching facility in Hyderabad. Part of the samples sent to Cardiff were analysed by a team at Cardiff University led by Professor David Lloyd and assisted by Melanie Harris.

    Commenting on the results, Professor Wickramasinghe said: "There is now unambiguous evidence for the presence of clumps of living cells in air samples from as high as 41 kilometres, well above the local tropopause (16 km), above which no air from lower down would normally be transported."

    The detection was made using a fluorescent cyanine dye which is only taken up by the membranes of living cells. The variation with height of the distribution of such cells indicates strongly that the clumps of bacterial cells are falling from space. The daily input of such biological material is provisionally estimated as about one third of a tonne over the entire planet.

    This new evidence provides strong support for the Panspermia theory of Sir Fred Hoyle and Chandra Wickramasinghe.

    "We have argued for more than two decades that terrestrial life was brought down to Earth by comets and that cometary material containing microorganisms must still be reaching us in large quantities," said Professor Wickramasinghe.
