Files and fossils



Not dinosaurs, but very neat article from Astrobiology that I thought might
be appropriate given some of the discussion concerning the place of
photographs/image-files contra actual specimens that has been going on here
recently.  The article is here:

http://www.astrobio.net/news/article415.html

It concerns devising a test to distnguish stromatolites from non-organic
stromatolite-like structures.  The test devised by the scientists mentioned
in the article works as follows: "create a digital image of the rock; then
compress the image file. The more the file shrinks, the more likely it is
that life was responsible for building the layers."

Cool stuff.  The rest is at the site.

Cheers,
