Life at molecular scale

Recently there are more and more amazing results in techniques allowing the visualization of life at molecular scale. Instead of the old story about soups of species of molecules, now we can see individual molecules in living cells [1], or that the coiled DNA has a complex chemical configuration, or that axons and dendrites interact in a far more complex way than imagined before. Life is based on a complex tangle of evolving individuals, from the molecular scale onwards.

To me, this gives hope that at some point chemists will start to  consider seriously the possibility to build such structures, such molecular computers [4] from first principles.
