Synthesis must be faster than degradation in the origin of life.
So somehow the UV is a more powerful force for synthesis than
degradation.
But how.

I've often talked about how life has evolved on four specific paths that can be called food in / waste out. Two paths or options to food in. Two paths or options to waste out.
The four options are
1 Nurturing* taken in.
2 Non nurturing (waste) blocked out.

Scientists Develop New Method to Investigate Origin of Life
(PhysOrg.com) -- Scientists at Penn State have developed a new computational
method that they say will help them to understand how life began on Earth.
The team's method has the potential to trace the evolutionary histories ...

Should life be defined as a single entity or a collection of species and
independent organisms. Either way can be valid. Light is considered both
wave and particle. And to accept one or the other definitions of life is not
science, it's assuming without proof.

Report: cells "from space" have unusual makeup

In microscopic scale chemical reactions are reversible - the dominant
direction depends of parameters (like ATPase H+).
Myosin can change ATP into movement. It's functions are too directed,
too complicated to be reversed in practice.

I have been reading a paper by Richared Lenski on a long running
experiment using e coli bacteria.
He says that they have taken a sample and frozen it every 500
generations.

I was just reading about the part protein-part RNA structure of ribosomes
and how the two different materials fit together structurally and was just
wondering: anything else in the cell like that?
