Some Physical Aspects of the Origin of Life and of Artificial Cells
Dr. Albert Libchaber, Rockefeller

We show first how a temperature gradient can lead to giant DNA accumulation by thermophoresis and to DNA sequence amplification in a convection set-up. Non-equilibrium thermodynamics can thus help to solve some nagging problems of critical concentration and sequence selection in a prebiotic soup. We show that a vesicle bioreactor can function for many days in an homeostatis state producing proteins. This is a first necessary step to artificial cells. The next step will be vesicle replication.
