Grad vor ein paar Tagen beim Blick auf das nach wie vor in unmittelbarer Bettnähe gelegene The Art of Prolog (gerade in halbmüdem Zustand grandioses Schlafmittel^*) gefragt, wie Ehud Shapiros DNA-Computing-Research vorangehen möge: Offensichtlich gut.

Yaakov Benenson, Binyamin Gil, Uri Ben-Dor, [create Rivka Adar] & Ehud Shapiro: An autonomous molecular computer for logical control of gene expression

"Here we describe an autonomous biomolecular computer that, at least in vitro, logically analyses the levels of messenger RNA species, and in response produces a molecule capable of affecting levels of gene expression. The computer operates at a concentration of close to a trillion computers per microlitre and consists of three programmable modules: a computation module, that is, a stochastic molecular automaton; an input module, by which specific mRNA levels or point mutations regulate software molecule concentrations, and hence automaton transition probabilities; and an output module, capable of controlled release of a short single-stranded DNA molecule."
