Advances in recent time in Von-neumann self replication idea I have read about Von-neumann self replication from  Theory of Self-reproducing automata, which are lecture notes reconstructed from lectures in book of the same name. Theory of Self-reproducing automata


  Its looks really interesting that neumann has formalize this even far before the discovery of DNA. I'm looking the work now from biological perspective and the work by Jeremy England his paper on Statistical Physics of Self-Replication and other similar work in irreversible biological process.


The work that Von-neumann did was around 50's. Is there any recent relevant work in this field based on the neumann's work. One that i could see is Enhancing the Robustness of
Self-Replication Processes 

Thank You.
For those who don't know, I am the world's only producer of a von Neumann 29-state self-replicating cellular automaton.
Indeed, respecting vNCA, I am the world's expert.  Ask Sayama (U Binghamton), Reggia(U of Maryland), or Adamatzky (U of South of England).
While DW may be a moderator, he does not know anything about von Neumann's cellular automata, I dare say he has not designed such self-replicators, and he certainly had not designed a machine zygote.  For my design of a machine zygote, see here:

One more thing, it is 29 states, not 28.
