Physicists Find Clue as To Why the DNA Double Helix Twists To the Right
New submitter Annanag writes Most organic molecules have left- or right-handed versions, mirror images of each other, just like gloves. For some reason, life always seems to favor one version over the other — the DNA double helix in its standard form always twists like a right-handed screw, for example. But why this preference for left or right happens has always been a mystery. Now, in an experiment that took 13 years to perfect, physicists have found hints that this asymmetry of life could have been caused by electrons from nuclear decay in the early days of evolution.
Depending on how you define "life", yes. In fact, almost certainly, regardless of which definition of "life" you choose. Selection can occur in any kind of chemical or physical process in which produces similar but not always identical results. There's nothing special about the particular chemical processes we call "life", nor some magic line in the sand you can draw and say "this is life, and this isn't" -- it gets rather fuzzy on the edges, and the distinction between life and other chemical processes is as arbitrary as the distinction between which celestial bodies we decide to call "planets" and which we decide don't qualify. Nature doesn't care much for our arbitrary distinctions.

If there's anything I learned from Star Trek TOS, is that no matter what planet you land on, you can always hook up with the local humanoid females.
