''Engineering ways to make biological systems perform computation is one of the core goals of synthetic biology. We generally work at the DNA level, engineering systems to function using BioBricks. In most biological systems, protein-protein interactions are where the majority of processing takes place. We design proteins to accomplish computation would allow for systems to function on a much faster timescale than the current transcription-translation paradigm. These are some of the challenges that face teams entering projects into the Information Processing track in iGEM.''  [http://2014.igem.org/Tracks/Information_Processing (iGEM)]

=== Pattern Emergence ===
We implement a cellular automaton in bacterial colonies. Each bacterial colony is a core, computing an XOR gate. A sensor device detects the inputs, HSL molecules. Then, the cell integrates the signal through a logic gate, performed by proteins, the serine integrases. A necessary post processing step generates the production of HSL molecules. Meanwhile, GFP, a visual read out, longlastingly indicates the state of the well. The produced signal then propagates in a directive fashion through a millifluidic chip. This iterative process faces the challenges of leakiness, cross-talk, protein-level computation and diffusion.
