Evolution of Information and Complexity in an Ever-Expanding Universe

Using the usual definitions of information and entropy in quantum gravity and statistical mechanics and the existing views about the relation between information and complexity, we examine the evolution of complexity in an ever expanding universe.

The Expanding Polymerase Universe

Escherichia coli DNA polymerase I (pol I), discovered by Arthur Kornberg and colleagues in 1956. Thirteen years later, Paula de Lucia and John Cairns, at Stony Brook, New York, isolated an E. coli mutant, polA (its designation being a play on de Lucia’s first name, as proposed to Cairns by Julian Gross) that seemed to have less than 1% of the normal pol I activity. From this strain, a new DNA-p...
