    It would seem we have found an atmospheric organism that replicates without DNA in meteor born cells falling as Red Rain...Whatcha think?

    MSM has not told us about this, so it must be a hoax? ha ha ha

    OTOH, we do get prolific information every time trump farts...and even an analysis. It seems he has a russian diet.

    Seriously, it appears interesting, a single cell replicating life form without the mandatory dna. If true, how long will it take the field of biology to edit text books? And how would a non dna self replicating single cell organism change current faith and beliefs?

    Well, there goes that it's settled science BS again....

    It would seem to me that this could be an extremely big deal.

    This isn't new.

    They've been sampling the upper atmosphere for a long time and are finding huge amounts of organic material entering from space.

    There are 100 billion stars in our galaxy. There are about 100 billion estimated galaxies observable.

    Yet we assume we're all there is.

    It's preposterous.

    A replicating cell with no DNA is definitely something new.

    There are viruses on earth that are RNA only.

    Anucleate cells exist in your own body.

    Yeah and they fall in rain all the time after meteors explode.

    That's cool. But how are they going to figure out if it's a threat to humanity unless they test it on humans???

    It has been tested on many thousands of humans who walked in the rain.

    I am aware that much organic matter is in space and in asteroids....this is a replicating cell without DNA. Perhaps you do not quite understand what that means?

    It would be interesting to see what kind of advanced animals might evolve from the DNA-less bacteria. And find out how they reproduce. But I don't have the time for that kind of wait.

    That's one unconfirmed claim from the events. There appear to be other, arguably better supported, hypotheses but they wouldn't make as dramatic television.

    Note that I'm only presenting Wikipedia as a starting point and not anything definitive. It's hardly perfect but it's still an infinitely better source than trash infotainment television clips. :cool:

    Did you miss the part where there are a lot of known organisms on earth that are RNA based and not DNA based?

    According to that he doesn't even have the training to test for DNA :roll:

    Regarding the "absence" of DNA, Louis admits he has no training in biology,[54][56] and has not reported the use of any standard microbiology growth medium to culture and induce germination and growth of the spores, basing his claim of "biological growth" on light absorption measurements following aggregation by supercritical fluids,[43] an inert physical observation. Both his collaborators, Wickramasinghe[57] and Milton Wainwright[25] independently extracted and confirmed the presence of DNA from the spores. The absence of DNA was key to Louis and Kumar's hypothesis that the cells were of extraterrestrial origins.[39]

    Louis' only reported attempt to stain the spores' DNA was by the use of malachite green, which is generally used to stain bacterial endospores, not algal spores,[58] whose primary function of their cell wall and their impermeability is to ensure its own survival through periods of environmental stress. They are therefore resistant to ultraviolet and gamma radiation, desiccation, lysozyme, temperature, starvation and chemical disinfectants. Visualizing algal spore DNA under a light microscope can be difficult due to the impermeability of the highly resistant spore wall to dyes and stains used in normal staining procedures. The spores' DNA is tightly packed, encapsulated and desiccated, therefore, the spores must first be cultured in suitable growth medium and temperature to first induce germination, then cell growth followed by reproduction before staining the DNA.[54]

    As far as I have seen ulterior explanations such as dust, algae, spores...etc..have been ruled out and potassium testing has also ruled out DNA/RNA.

    Nope...I also note the data indicating potassium testing has ruled out DNA/RNA.

    They Rule The Universe.
    Even known to incorporate DNA that may benefit a particular circumstance.

    Where did they evolve first?

    After they take control

    Sadly, evolutionarily limited.

    No one has made a "mechanical tentacle". Cool, huh.
    If we understood how they worked, we could make one.

    Imagine an advanced cephlopod that could do independent tasks with each tentacle.
    Consider, Oxygen from water is just not as efficient as Oxygen from atmosphere.
    And they can't handle the atmosphere.



    The tardigrade is a multicellular animal that can withstand the trauma of space.
    Suitable for meteorite spread.

    Nothing in the Wikipedia article references ruling out the presence of DNA and it doesn’t mention potassium at all. Where are you getting that from?

    The quotes (with references) suggest, at best, a difference of opinion on the question;

    “Parts of the CESS/TBGRI report were supported by Milton Wainwright at Sheffield University, who, together with Chandra Wickramasinghe, has studied stratospheric spores.[1][23] In March 2006 Wainwright said the particles were similar in appearance to spores of a rust fungus,[24] later saying that he had confirmed the presence of DNA,[25] and reported their similarity to algal spores, and found no evidence to suggest that the rain contained dust, sand, fat globules, or blood.”

    “In 2003 Godfrey Louis and Santhosh Kumar, physicists at the Mahatma Gandhi University in Kottayam, Kerala, posted an article entitled "Cometary panspermia explains the red rain of Kerala"[39] in the non-peer reviewed arXiv web site… Their work indicated that the particles were of biological origin (consistent with the CESS report), however, they invoked the panspermia hypothesis to explain the presence of cells in a supposed fall of meteoric material.[40][41][42] Additionally, using ethidium bromide they were unable to detect DNA or RNA in the particles.”

    So you’re not going to say where you saw all those other possible explanations being ruled out and potassium testing ruling out the presence of DNA? :cool:
