Scientists have discovered a way of recognizing the signs of life in rock formations. Essentially: 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.
Although biological stromatolites and non-biological stromatolite-look-alike structures appear similar to the human eye, the biological origin of stromatolites makes them more ordered, more highly patterned. And it is this patterning that, while hard for the human eye to discern, is readily detected by the compression algorithm. Non-biological stromatolite-like structures are more random, less patterned and therefore less compressible.
An online test is here. Hm, interesting. Is higher life forms more or less compressible? Would the ultimate life forms be the most compressible and embeddable? Does all of life reduce to a beautiful little formula?

Fixed term elections, mndaatory requirement for everyone to vote in elections, local income tax, goverment funding for all major parties, referendums on major issues such as new EU treaty, abolishment of Royalty involvement in politics, public to vote for all members of House of Lords and of course proportional representation should all be required in a modern, democratic, fair nation.

I’ve been trying to add the blogfrog widgets to my blog but for some reason they wo&278n1#;t work. Holly is trying to figure out why. It looks like a neat program. Just wish I could get it to work. [link] [url=http://bqommiqptqu.com]bqommiqptqu[/url] [link=http://addijnu.com]addijnu[/link]
