Physicist Derives Laws of Thermodynamics For Life Itself

Physicist Derives Laws of Thermodynamics For Life Itself:  His idea is to examine every combination of states that are possible in this box and to consult an omniscient microbiologist about whether each state represents a bacterium or not. In that way, it ought to be possible, at least in principle, to gain an idea of the statistical physics involved.

Next, he asks the microbiologist to take another look at the box after a period that is roughly equivalent to the time it takes for bacteria to divide...

This sets an important bound on what is thermodynamically possible in this system: in effect, England derives the second law of thermodynamics for the system...

First replicating creature spawned in life simulator - physics-math - 16 June 2010 - New Scientist

First replicating creature spawned in life simulator - physics-math - 16 June 2010 - New Scientist: "The 'offspring' is identical to its parent, but it has shifted up and slightly to the left - another first for Life: every other known pattern moves along one of the eight compass points, but Gemini travels across the grid in a north by north-west direction."

Self-starter: Life got going all on its own

the genetic code is the inevitable consequence of affinities between the molecular building blocks of RNA and those of the proteins they code for. If he's right, it will explain why individual triplets always code for the same amino acids, whether in a virus or a human.
