Bioengineers add cooperative molecules to their toolkit for programming signal processing
(PHYSorg.com Biology)

Elaborate molecular networks inside living cells enable them to sense and process many signals from the environment to perform desired cellular functions. Synthetic biologists have been able to reconstruct and mimic simpler forms of this cellular signal processing. But now, a new toolset powered by self-assembling molecules and predictive modeling will allow researchers to construct the complex computation and signal processing found in eukaryotic organisms, including human cells.
