Cool story but I am more than a little sceptical. Some of the cells tested positive for DNA and the other cells may be red blood cells which would not have DNA but also would not reproduce.

I would love to read the paper and not have to rely on a reporter's account of what he got from it. It is strange that the paper was published in an Astrophysics journal (Astrophysics and Space Science ) rather than in Nature, The Scientist, or AMS Journal for Microbiology.

Red Blood Cells wouldnt survive contact with water.. They would lyse because they are hypertonic to water.. Those cant be red blood cells.

Additionally, there is no way they would survive 600 degrees F.

If you believe that they came from space and dismiss the idea that the cells are terrestrial. There is no real evidence that they survive at 600 degrees other than the author's word.

Umm, the researcher posted his findings in a peer reviewed journal... He did tests on them, and they survived temperatures of 600 degrees.. Nontheless, they cant be red blood cells, because they explode when they come into contact with water.

Microbiology experiments conducted by a solid-state physicist and peer reviewed by other physicists? The only experiment done by a microbiologist showed DNA.

Also, RBCs don't necessarily lyse in distilled water. Every experiement I have done in which I had to lyse RBCs, I had to use a lysis buffer or add PBS to the solution

Sorry bro. I have a Master's in Microbiology and Molecular Biology and, while I'd love to suspend my beliefs and buy into the alien theory, I think there is another explaination

Well, they are still waiting for the results from replicated experiments on the specimen..

But, Red Blood Cells dont have strong enough cell walls to allow for the excess of water that will try to pour into the cell.. How on earth could they "rain" from a cloud?

I don't know my friend but I remain suspicious. I'll wait for the Micro experiments.

they may indead be some sort of bacteria like substance from outer space, that would mean it is alien life because of the pure definition of life. Very interesting. on a side note, they really dont look like red blood cells.

What if it is a toxic virus...it could kill us all like in that movie, "The Blob." :eek:

There are mixed cells. If anyone is interested, the full paper can be found here (http://arxiv.org/abs/astro-ph/0601022). There are lots more pictures. The paper concentrates more on the 'red rain' than the science of figuring out what the cells are and the analysis of nucleic acids (negative) was later disproven on at least one sample that was tested by a Micro lab.

It remains a mystery. It will be interesting to see what a full analysis will yield.

Here's the latest analysis (http://www.astrobiology.cf.ac.uk/redrain.html) and pictures showing the formation of daughter cells (http://en.wikipedia.org/wiki/Daughter_cell).

The study is ongoing and is being done by Cardiff University. Analysis of the parent and daughter cells show the presumptive presence of DNA.


Further work in progress has yeilded positive for DNA using DAPI staining in the cells and daughters. However, this identification is not yet fully confirmed, and might be considered equivocal. We hope to pursue our efforts in extracting DNA (if it exists), amplifying it and carrying out genetic sequencing, but his work takes time.
If you look at the daughter cells, they appear to have some type of dark mass in the center of the cell. Could be organelles (http://en.wikipedia.org/wiki/Organelles)...Eukaryotic (http://en.wikipedia.org/wiki/Eukaryote) cells, perhaps...eukaryotic cells with cell walls (http://en.wikipedia.org/wiki/Cell_wall)?

Given that they can allegedly survive at high temps (http://en.wikipedia.org/wiki/Extremeophile) and their odd structure, I am guessing archaea
(http://en.wikipedia.org/wiki/Archaea)

the red rain reminds me of the spores from the Pern series
