you should look at this piece of information
As if space travel was not
already filled with enough dangers, a new study out today in the journal PLOS
ONE shows that cosmic radiation -- which would bombard astronauts on deep
space missions to places like Mars -- could accelerate the onset of
Alzheimer's disease.
In a forced game of molecular tug-of war, some strings
of atoms can act like a lever, accelerating reactions 1000 times faster than
other molecules. The discovery suggests that scientists could use these
molecular levers to drive chemical and mechanical reactivity among atoms and
ultimately engineer more efficient materials.
As it is for humans, zinc is
essential for a wide range of basic cellular processes. Zinc-binding
proteins, primarily located in the cell nucleus, are involved in the
regulation of gene transcription.

One approach
to understanding components in living organisms is to attempt to create them
artificially, using principles of chemistry, engineering and genetics. A
suite of powerful techniques -- collectively referred to as synthetic biology
-- have been used to produce self-replicating molecules, artificial pathways
in living systems and organisms bearing synthetic genomes.
