Panspermia Gets Another Boost

Panspermia gets another boost.

For those who don’t know panspermia is the theory that life may not have started here on earth. It might have come on comets or meteoric dust particles that drift into the earth’s gravity well and then into the atmosphere.

The new boost is a test recently done where they applied plasmid DNA molecules to the outside of body panels of a spacecraft before launching. Then they checked after re-entry. All the panels they had painted with DNA still had salvageable DNA. And when they checked most of this DNA was still able to transmit genetic information to bacterial and connective tissue!

Now this was plasmid DNA, not a spore. It ‘survived’ launch, space and re-entry into the atmosphere. Not too shabby for a molecule.

Most things I do involve computers. Nowadays that sounds stupid to hear because everyone uses computers. Except I was saying that before the IBM PC came on the scene. (hint: my first programs were entered on punch cards in an IBM-29) Now I mostly use them. Mostly to provide a community service in my small town. Because I could when it was asked and still can. And I'm a wannabe writer. Various books in various states of incompleteness. A few short stories. Might do more of that.
